There +# wouldn't be a problem if people could stick to purely numeric version +# numbers: just split on period and compare the numbers as tuples. +# However, people insist on putting letters into their version numbers; +# the most common purpose seems to be: +# - indicating a "pre-release" version +# ('alpha', 'beta', 'a', 'b', 'pre', 'p') +# - indicating a post-release patch ('p', 'pl', 'patch') +# but of course this can't cover all version number schemes, and there's +# no way to know what a programmer means without asking him. +# +# The problem is what to do with letters (and other non-numeric +# characters) in a version number. The current implementation does the +# obvious and predictable thing: keep them as strings and compare +# lexically within a tuple comparison. This has the desired effect if +# an appended letter sequence implies something "post-release": +# eg. "0.99" < "0.99pl14" < "1.0", and "5.001" < "5.001m" < "5.002". +# +# However, if letters in a version number imply a pre-release version, +# the "obvious" thing isn't correct. Eg. you would expect that +# "1.5.1" < "1.5.2a2" < "1.5.2", but under the tuple/lexical comparison +# implemented here, this just isn't so. +# +# Two possible solutions come to mind. The first is to tie the +# comparison algorithm to a particular set of semantic rules, as has +# been done in the StrictVersion class above. This works great as long +# as everyone can go along with bondage and discipline. Hopefully a +# (large) subset of Python module programmers will agree that the +# particular flavour of bondage and discipline provided by StrictVersion +# provides enough benefit to be worth using, and will submit their +# version numbering scheme to its domination. The free-thinking +# anarchists in the lot will never give in, though, and something needs +# to be done to accommodate them. +# +# Perhaps a "moderately strict" version class could be implemented that +# lets almost anything slide (syntactically), and makes some heuristic +# assumptions about non-digits in version number strings. This could +# sink into special-case-hell, though; if I was as talented and +# idiosyncratic as Larry Wall, I'd go ahead and implement a class that +# somehow knows that "1.2.1" < "1.2.2a2" < "1.2.2" < "1.2.2pl3", and is +# just as happy dealing with things like "2g6" and "1.13++". I don't +# think I'm smart enough to do it right though. +# +# In any case, I've coded the test suite for this module (see +# ../test/test_version.py) specifically to fail on things like comparing +# "1.2a2" and "1.2". That's not because the *code* is doing anything +# wrong, it's because the simple, obvious design doesn't match my +# complicated, hairy expectations for real-world version numbers.

It converts the function's parameter signature into command-line arguments, and automatically runs the function if the module was called as `__main__`. In effect, it lets your create a smart main function. + +```python +from autocommand import autocommand + +# This program takes exactly one argument and echos it. +@autocommand(__name__) +def echo(thing): + print(thing) +``` + +``` +$ python echo.py hello +hello +$ python echo.py -h +usage: echo [-h] thing + +positional arguments: + thing + +optional arguments: + -h, --help show this help message and exit +$ python echo.py hello world # too many arguments +usage: echo.py [-h] thing +echo.py: error: unrecognized arguments: world +``` + +As you can see, autocommand converts the signature of the function into an argument spec. When you run the file as a program, autocommand collects the command-line arguments and turns them into function arguments. The function is executed with these arguments, and then the program exits with the return value of the function, via `sys.exit`. Autocommand also automatically creates a usage message, which can be invoked with `-h` or `--help`, and automatically prints an error message when provided with invalid arguments. + +### Types + +You can use a type annotation to give an argument a type. Any type (or in fact any callable) that returns an object when given a string argument can be used, though there are a few special cases that are described later. + +```python +@autocommand(__name__) +def net_client(host, port: int): + ... +``` + +Autocommand will catch `TypeErrors` raised by the type during argument parsing, so you can supply a callable and do some basic argument validation as well. + +### Trailing Arguments + +You can add a `*args` parameter to your function to give it trailing arguments. The command will collect 0 or more trailing arguments and supply them to `args` as a tuple. If a type annotation is supplied, the type is applied to each argument. + +```python +# Write the contents of each file, one by one +@autocommand(__name__) +def cat(*files): + for filename in files: + with open(filename) as file: + for line in file: + print(line.rstrip()) +``` + +``` +$ python cat.py -h +usage: ipython [-h] [file [file ...]] + +positional arguments: + file + +optional arguments: + -h, --help show this help message and exit +``` + +### Options + +To create `--option` switches, just assign a default.

Pass `add_nos=True` to `autocommand` to enable this. + +``` + @autocommand(__name__, add_nos=True) + def example(verbose=False): + pass +``` + +``` +$ python example.py -h +usage: ipython [-h] [-v] [--no-verbose] + +optional arguments: + -h, --help show this help message and exit + -v, --verbose + --no-verbose +``` + +Using the `--no-` version of a switch will pass the opposite value in as a function argument. If multiple switches are present, the last one takes precedence. + +#### Files + +If the default value is a file object, such as `sys.stdout`, then autocommand just looks for a string, for a file path. It doesn't do any special checking on the string, though (such as checking if the file exists); it's better to let the client decide how to handle errors in this case. Instead, it provides a special context manager called `smart_open`, which behaves exactly like `open` if a filename or other openable type is provided, but also lets you use already open files: + +```python +from autocommand import autocommand, smart_open +import sys + +# Write the contents of stdin, or a file, to stdout +@autocommand(__name__) +def write_out(infile=sys.stdin): + with smart_open(infile) as f: + for line in f: + print(line.rstrip()) + # If a file was opened, it is closed here. If it was just stdin, it is untouched. +``` + +``` +$ echo "Hello World!" | python write_out.py | tee hello.txt +Hello World! +$ python write_out.py --infile hello.txt +Hello World! +``` + +### Descriptions and docstrings + +The `autocommand` decorator accepts `description` and `epilog` kwargs, corresponding to the `description `_ and `epilog `_ of the `ArgumentParser`. If no description is given, but the decorated function has a docstring, then it is taken as the `description` for the `ArgumentParser`. You can also provide both the description and epilog in the docstring by splitting it into two sections with 4 or more - characters. + +```python +@autocommand(__name__) +def copy(infile=sys.stdin, outfile=sys.stdout): + ''' + Copy an the contents of a file (or stdin) to another file (or stdout) + ---------- + Some extra documentation in the epilog + ''' + with smart_open(infile) as istr: + with smart_open(outfile, 'w') as ostr: + for line in istr: + ostr.write(line) +``` + +``` +$ python copy.py -h +usage: copy.py [-h] [-i INFILE] [-o OUTFILE] + +Copy an the contents of a file (or stdin) to another file (or stdout) + +optional arguments: + -h, --help show this help message and exit + -i INFILE, --infile INFILE + -o OUTFILE, --outfile OUTFILE + +Some extra documentation in the epilog +$ echo "Hello World" | python copy.py --outfile hello.txt +$ python copy.py --infile hello.txt --outfile hello2.txt +$ python copy.py --infile hello2.txt +Hello World +``` + +### Parameter descriptions + +You can also attach description text to individual parameters in the annotation. To attach both a type and a description, supply them both in any order in a tuple + +```python +@autocommand(__name__) +def copy_net( + infile: 'The name of the file to send', + host: 'The host to send the file to', + port: (int, 'The port to connect to')): + + ''' + Copy a file over raw TCP to a remote destination. + ''' + # Left as an exercise to the reader +``` + +### Decorators and wrappers + +Autocommand automatically follows wrapper chains created by `@functools.wraps`. This means that you can apply other wrapping decorators to your main function, and autocommand will still correctly detect the signature. + +```python +from functools import wraps +from autocommand import autocommand + +def print_yielded(func): + ''' + Convert a generator into a function that prints all yielded elements + ''' + @wraps(func) + def wrapper(*args, **kwargs): + for thing in func(*args, **kwargs): + print(thing) + return wrapper + +@autocommand(__name__, + description= 'Print all the values from START to STOP, inclusive, in steps of STEP', + epilog= 'STOP and STEP default to 1') +@print_yielded +def seq(stop, start=1, step=1): + for i in range(start, stop + 1, step): + yield i +``` + +``` +$ seq.py -h +usage: seq.py [-h] [-s START] [-S STEP] stop + +Print all the values from START to STOP, inclusive, in steps of STEP + +positional arguments: + stop + +optional arguments: + -h, --help show this help message and exit + -s START, --start START + -S STEP, --step STEP + +STOP and STEP default to 1 +``` + +Even though autocommand is being applied to the `wrapper` returned by `print_yielded`, it still retreives the signature of the underlying `seq` function to create the argument parsing. + +### Custom Parser + +While autocommand's automatic parser generator is a powerful convenience, it doesn't cover all of the different features that argparse provides. If you need these features, you can provide your own parser as a kwarg to `autocommand`: + +```python +from argparse import ArgumentParser +from autocommand import autocommand + +parser = ArgumentParser() +# autocommand can't do optional positonal parameters +parser.add_argument('arg', nargs='?') +# or mutually exclusive options +group = parser.add_mutually_exclusive_group() +group.add_argument('-v', '--verbose', action='store_true') +group.add_argument('-q', '--quiet', action='store_true') + +@autocommand(__name__, parser=parser) +def main(arg, verbose, quiet): + print(arg, verbose, quiet) +``` + +``` +$ python parser.py -h +usage: write_file.py [-h] [-v | -q] [arg] + +positional arguments: + arg + +optional arguments: + -h, --help show this help message and exit + -v, --verbose + -q, --quiet +$ python parser.py +None False False +$ python parser.py hello +hello False False +$ python parser.py -v +None True False +$ python parser.py -q +None False True +$ python parser.py -vq +usage: parser.py [-h] [-v | -q] [arg] +parser.py: error: argument -q/--quiet: not allowed with argument -v/--verbose +``` + +Any parser should work fine, so long as each of the parser's arguments has a corresponding parameter in the decorated main function. The order of parameters doesn't matter, as long as they are all present. Note that when using a custom parser, autocommand doesn't modify the parser or the retrieved arguments. This means that no description/epilog will be added, and the function's type annotations and defaults (if present) will be ignored. + +## Testing and Library use + +The decorated function is only called and exited from if the first argument to `autocommand` is `'__main__'` or `True`. If it is neither of these values, or no argument is given, then a new main function is created by the decorator. This function has the signature `main(argv=None)`, and is intended to be called with arguments as if via `main(sys.argv[1:])`. The function has the attributes `parser` and `main`, which are the generated `ArgumentParser` and the original main function that was decorated. This is to facilitate testing and library use of your main. Calling the function triggers a `parse_args()` with the supplied arguments, and returns the result of the main function. Note that, while it returns instead of calling `sys.exit`, the `parse_args()` function will raise a `SystemExit` in the event of a parsing error or `-h/--help` argument. + +```python + @autocommand() + def test_prog(arg1, arg2: int, quiet=False, verbose=False): + if not quiet: + print(arg1, arg2) + if verbose: + print("LOUD NOISES") + + return 0 + + print(test_prog(['-v', 'hello', '80'])) +``` + +``` +$ python test_prog.py +hello 80 +LOUD NOISES +0 +``` + +If the function is called with no arguments, `sys.argv[1:]` is used. This is to allow the autocommand function to be used as a setuptools entry point. + +## Exceptions and limitations + +- There are a few possible exceptions that `autocommand` can raise. All of them derive from `autocommand.AutocommandError`. + + - If an invalid annotation is given (that is, it isn't a `type`, `str`, `(type, str)`, or `(str, type)`, an `AnnotationError` is raised. The `type` may be any callable, as described in the `Types`_ section. + - If the function has a `**kwargs` parameter, a `KWargError` is raised. + - If, somehow, the function has a positional-only parameter, a `PositionalArgError` is raised. This means that the argument doesn't have a name, which is currently not possible with a plain `def` or `lambda`, though many built-in functions have this kind of parameter. + +- There are a few argparse features that are not supported by autocommand. + + - It isn't possible to have an optional positional argument (as opposed to a `--option`). POSIX thinks this is bad form anyway. + - It isn't possible to have mutually exclusive arguments or options + - It isn't possible to have subcommands or subparsers, though I'm working on a few solutions involving classes or nested function definitions to allow this. + +## Development + +Autocommand cannot be important from the project root; this is to enforce separation of concerns and prevent accidental importing of `setup.py` or tests. To develop, install the project in editable mode: + +``` +$ python setup.py develop +``` + +This will create a link to the source files in the deployment directory, so that any source changes are reflected when it is imported. diff --git a/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/RECORD b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/RECORD new file mode 100644 index 0000000000000000000000000000000000000000..8cd7450980bb1cf4d7646611ae6d64b6a9853b35 --- /dev/null +++ b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/RECORD @@ -0,0 +1,13 @@ +autocommand-2.2.2.dist-info/INSTALLER,sha256=5hhM4Q4mYTT9z6QB6PGpUAW81PGNFrYrdXMj4oM_6ak,2 +autocommand-2.2.2.dist-info/LICENSE,sha256=reeNBJgtaZctREqOFKlPh6IzTdOFXMgDSOqOJAqg3y0,7634 +autocommand-2.2.2.dist-info/METADATA,sha256=OADZuR3O6iBlpu1ieTgzYul6w4uOVrk0P0BO5TGGAJk,15006 +autocommand-2.2.2.dist-info/RECORD,, +autocommand-2.2.2.dist-info/REQUESTED,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 +autocommand-2.2.2.dist-info/WHEEL,sha256=2wepM1nk4DS4eFpYrW1TTqPcoGNfHhhO_i5m4cOimbo,92 +autocommand-2.2.2.dist-info/top_level.txt,sha256=AzfhgKKS8EdAwWUTSF8mgeVQbXOY9kokHB6kSqwwqu0,12 +autocommand/__init__.py,sha256=zko5Rnvolvb-UXjCx_2ArPTGBWwUK5QY4LIQIKYR7As,1037 +autocommand/autoasync.py,sha256=AMdyrxNS4pqWJfP_xuoOcImOHWD-qT7x06wmKN1Vp-U,5680 +autocommand/autocommand.py,sha256=hmkEmQ72HtL55gnURVjDOnsfYlGd5lLXbvT4KG496Qw,2505 +autocommand/automain.py,sha256=A2b8i754Mxc_DjU9WFr6vqYDWlhz0cn8miu8d8EsxV8,2076 +autocommand/autoparse.py,sha256=WVWmZJPcbzUKXP40raQw_0HD8qPJ2V9VG1eFFmmnFxw,11642 +autocommand/errors.py,sha256=7aa3roh9Herd6nIKpQHNWEslWE8oq7GiHYVUuRqORnA,886 diff --git a/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/REQUESTED b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/REQUESTED new file mode 100644 index 0000000000000000000000000000000000000000..e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 diff --git a/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/WHEEL b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/WHEEL new file mode 100644 index 0000000000000000000000000000000000000000..57e3d840d59a650ac5bccbad5baeec47d155f0ad --- /dev/null +++ b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/WHEEL @@ -0,0 +1,5 @@ +Wheel-Version: 1.0 +Generator: bdist_wheel (0.38.4) +Root-Is-Purelib: true +Tag: py3-none-any + diff --git a/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/top_level.txt b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/top_level.txt new file mode 100644 index 0000000000000000000000000000000000000000..dda5158ff6d263927861b19ef5a5d183d2aa77ed --- /dev/null +++ b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand-2.2.2.dist-info/top_level.txt @@ -0,0 +1 @@ +autocommand diff --git a/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand/__init__.py b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand/__init__.py new file mode 100644 index 0000000000000000000000000000000000000000..73fbfca6b36927c6371839df3dfe733bebb2066f --- /dev/null +++ b/python/user_packages/Python313/site-packages/setuptools/_vendor/autocommand/__init__.py @@ -0,0 +1,27 @@ +# Copyright 2014-2016 Nathan West +# +# This file is part of autocommand. +# +# autocommand is free software: you can redistribute it and/or modify +# it under the terms of the GNU Lesser General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# autocommand is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Includes ``passes`` and ``raises`` decorators to replace the result of a wrapped function by a boolean indicating the outcome of the exception trap. See `this keyring commit `_ for an example of it in production. +- ``suppress`` simply enables ``contextlib.suppress`` as a decorator. +- ``on_interrupt`` is a decorator used by CLI entry points to affect the handling of a ``KeyboardInterrupt``.

+
+When writing desktop application, finding the right location to store user data
+and configuration varies per platform. Even for single-platform apps, there
+may by plenty of nuances in figuring out the right location.
+
+For example, if running on macOS, you should use::
+
+    ~/Library/Application Support/
+
+If on Windows (at least English Win) that should be::
+
+    C:\Documents and Settings\\Application Data\Local Settings\\
+
+or possibly::
+
+    C:\Documents and Settings\\Application Data\\
+
+for `roaming profiles `_ but that is another story.
+
+On Linux (and other Unices), according to the `XDG Basedir Spec`_, it should be::
+
+    ~/.local/share/
+
+.. _XDG Basedir Spec: https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html
+
+``platformdirs`` to the rescue
+==============================
+
+This kind of thing is what the ``platformdirs`` package is for.
+``platformdirs`` will help you choose an appropriate:
+
+- user data dir (``user_data_dir``)
+- user config dir (``user_config_dir``)
+- user cache dir (``user_cache_dir``)
+- site data dir (``site_data_dir``)
+- site config dir (``site_config_dir``)
+- user log dir (``user_log_dir``)
+- user documents dir (``user_documents_dir``)
+- user downloads dir (``user_downloads_dir``)
+- user pictures dir (``user_pictures_dir``)
+- user videos dir (``user_videos_dir``)
+- user music dir (``user_music_dir``)
+- user desktop dir (``user_desktop_dir``)
+- user runtime dir (``user_runtime_dir``)
+
+And also:
+
+- Is slightly opinionated on the directory names used. Look for "OPINION" in
+  documentation and code for when an opinion is being applied.
+
+Example output

+
+Note: Some android apps like Termux and Pydroid are used as shells. These
+apps are used by the end user to emulate Linux environment. Presence of
+``SHELL`` environment variable is used by Platformdirs to differentiate
+between general android apps and android apps used as shells. Shell android
+apps also support ``XDG_*`` environment variables.

+
+``PlatformDirs`` for convenience
+================================
+
+.. code-block:: pycon
+
+    >>> from platformdirs import PlatformDirs
+    >>> dirs = PlatformDirs("SuperApp", "Acme")
+    >>> dirs.user_data_dir
+    '/Users/trentm/Library/Application Support/SuperApp'
+    >>> dirs.user_config_dir
+    '/Users/trentm/Library/Application Support/SuperApp'
+    >>> dirs.user_cache_dir
+    '/Users/trentm/Library/Caches/SuperApp'
+    >>> dirs.site_data_dir
+    '/Library/Application Support/SuperApp'
+    >>> dirs.site_config_dir
+    '/Library/Application Support/SuperApp'
+    >>> dirs.user_cache_dir

+    >>> dirs.user_log_dir

+    '/Users/trentm/Movies'
+    >>> dirs.user_music_dir
+    '/Users/trentm/Music'
+    >>> dirs.user_desktop_dir
+    '/Users/trentm/Desktop'
+    >>> dirs.user_runtime_dir
+    '/Users/trentm/Library/Caches/TemporaryItems/SuperApp'
+
+Per-version isolation
+=====================
+
+If you have multiple versions of your app in use that you want to be
+able to run side-by-side, then you may want version-isolation for these
+dirs::
+
+    >>> from platformdirs import PlatformDirs
+    >>> dirs = PlatformDirs("SuperApp", "Acme", version="1.0")
+    >>> dirs.user_data_dir
+    '/Users/trentm/Library/Application Support/SuperApp/1.0'
+    >>> dirs.user_config_dir
+    '/Users/trentm/Library/Application Support/SuperApp/1.0'
+    >>> dirs.user_cache_dir
+    '/Users/trentm/Library/Caches/SuperApp/1.0'
+    >>> dirs.site_data_dir
+    '/Library/Application Support/SuperApp/1.0'
+    >>> dirs.site_config_dir
+    '/Library/Application Support/SuperApp/1.0'
+    >>> dirs.user_log_dir
+    '/Users/trentm/Library/Logs/SuperApp/1.0'
+    >>> dirs.user_documents_dir
+    '/Users/trentm/Documents'
+    >>> dirs.user_downloads_dir
+    '/Users/trentm/Downloads'
+    >>> dirs.user_pictures_dir
+    '/Users/trentm/Pictures'
+    >>> dirs.user_videos_dir
+    '/Users/trentm/Movies'
+    >>> dirs.user_music_dir
+    '/Users/trentm/Music'
+    >>> dirs.user_desktop_dir
+    '/Users/trentm/Desktop'
+    >>> dirs.user_runtime_dir
+    '/Users/trentm/Library/Caches/TemporaryItems/SuperApp/1.0'
+
+Be wary of using this for configuration files though; you'll need to handle
+migrating configuration files manually.
+
+Why this Fork?
+==============
+
+This repository is a friendly fork of the wonderful work started by
+`ActiveState `_ who created
+``appdirs``, this package's ancestor.
+
+Maintaining an open source project is no easy task, particularly
+from within an organization, and the Python community is indebted
+to ``appdirs`` (and to Trent Mick and Jeff Rouse in particular) for
+creating an incredibly useful simple module, as evidenced by the wide
+number of users it has attracted over the years.
+
+Nonetheless, given the number of long-standing open issues
+and pull requests, and no clear path towards `ensuring
+that maintenance of the package would continue or grow
+`_, this fork was
+created.
+
+Contributions are most welcome.

+
+## Intro
+
+Tomli is a Python library for parsing [TOML](https://toml.io).
+Version 2.4.0 and later are compatible with [TOML v1.1.0](https://toml.io/en/v1.1.0).
+Older versions are [TOML v1.0.0](https://toml.io/en/v1.0.0) compatible.
+
+A version of Tomli, the `tomllib` module,
+was added to the standard library in Python 3.11
+via [PEP 680](https://www.python.org/dev/peps/pep-0680/).
+Tomli continues to provide a backport on PyPI for Python versions
+where the standard library module is not available
+and that have not yet reached their end-of-life.
+
+Tomli uses [mypyc](https://github.com/mypyc/mypyc)
+to generate binary wheels for most of the widely used platforms,
+so Python 3.11+ users may prefer it over `tomllib` for improved performance.
+Pure Python wheels are available on any platform and should perform the same as `tomllib`.
+
+## Installation
+
+```bash
+pip install tomli
+```
+
+## Usage
+
+### Parse a TOML string
+
+```python
+import tomli
+
+toml_str = """
+[[players]]
+name = "Lehtinen"
+number = 26
+
+[[players]]
+name = "Numminen"
+number = 27
+"""
+
+toml_dict = tomli.loads(toml_str)
+assert toml_dict == {
+    "players": [{"name": "Lehtinen", "number": 26}, {"name": "Numminen", "number": 27}]
+}
+```
+
+### Parse a TOML file
+
+```python
+import tomli
+
+with open("path_to_file/conf.toml", "rb") as f:
+    toml_dict = tomli.load(f)
+```
+
+The file must be opened in binary mode (with the `"rb"` flag).
+Binary mode will enforce decoding the file as UTF-8 with universal newlines disabled,
+both of which are required to correctly parse TOML.
+
+### Handle invalid TOML
+
+```python
+import tomli
+
+try:
+    toml_dict = tomli.loads("]] this is invalid TOML [[")
+except tomli.TOMLDecodeError:
+    print("Yep, definitely not valid.")
+```
+
+Note that error messages are considered informational only.
+They should not be assumed to stay constant across Tomli versions.
+
+### Construct `decimal.Decimal`s from TOML floats
+
+```python
+from decimal import Decimal
+import tomli
+
+toml_dict = tomli.loads("precision-matters = 0.982492", parse_float=Decimal)
+assert isinstance(toml_dict["precision-matters"], Decimal)
+assert toml_dict["precision-matters"] == Decimal("0.982492")
+```
+
+Note that `decimal.Decimal` can be replaced with another callable that converts a TOML float from string to a Python type.
+The `decimal.Decimal` is, however, a practical choice for use cases where float inaccuracies can not be tolerated.
+
+Illegal types are `dict` and `list`, and their subtypes.
+A `ValueError` will be raised if `parse_float` produces illegal types.
+
+### Building a `tomli`/`tomllib` compatibility layer
+
+Python versions 3.11+ ship with a version of Tomli:
+the `tomllib` standard library module.
+To build code that uses the standard library if available,
+but still works seamlessly with Python 3.6+,
+do the following.
+
+Instead of a hard Tomli dependency, use the following
+[dependency specifier](https://packaging.python.org/en/latest/specifications/dependency-specifiers/)
+to only require Tomli when the standard library module is not available:
+
+```
+tomli >= 1.1.0 ; python_version < "3.11"
+```
+
+Then, in your code, import a TOML parser using the following fallback mechanism:
+
+```python
+import sys
+
+if sys.version_info >= (3, 11):
+    import tomllib
+else:
+    import tomli as tomllib
+
+tomllib.loads("['This parses fine with Python 3.6+']")
+```
+
+## FAQ
+
+### Why this parser?
+
+- it's lil'
+- pure Python with zero dependencies
+- the fastest pure Python parser [\*](#pure-python):
+  18x as fast as [tomlkit](https://pypi.org/project/tomlkit/),
+  2.1x as fast as [toml](https://pypi.org/project/toml/)
+- outputs [basic data types](#how-do-toml-types-map-into-python-types) only
+- 100% spec compliant: passes all tests in
+  [toml-lang/toml-test](https://github.com/toml-lang/toml-test)
+  test suite
+- thoroughly tested: 100% branch coverage
+
+### Is comment preserving round-trip parsing supported?
+
+No.
+
+The `tomli.loads` function returns a plain `dict` that is populated with builtin types and types from the standard library only.
+Preserving comments requires a custom type to be returned so will not be supported,
+at least not by the `tomli.loads` and `tomli.load` functions.
+
+Look into [TOML Kit](https://github.com/sdispater/tomlkit) if preservation of style is what you need.
+
+### Is there a `dumps`, `write` or `encode` function?
+
+[Tomli-W](https://github.com/hukkin/tomli-w) is the write-only counterpart of Tomli, providing `dump` and `dumps` functions.
+
+The core library does not include write capability, as most TOML use cases are read-only, and Tomli intends to be minimal.
+
+### How do TOML types map into Python types?
+
+| TOML type        | Python type         | Details                                                      |
+| ---------------- | ------------------- | ------------------------------------------------------------ |

+wheel
+=====
+
+This is a command line tool for manipulating Python wheel files, as defined in
+`PEP 427`_. It contains the following functionality:
+
+* Convert ``.egg`` archives into ``.whl``
+* Unpack wheel archives
+* Repack wheel archives
+* Add or remove tags in existing wheel archives
+
+.. _PEP 427: https://www.python.org/dev/peps/pep-0427/
+
+Historical note
+---------------
+
+This project used to contain the implementation of the setuptools_ ``bdist_wheel``
+command, but as of setuptools v70.1, it no longer needs ``wheel`` installed for that to
+work. Thus, you should install this **only** if you intend to use the ``wheel`` command
+line tool!
+
+.. _setuptools: https://pypi.org/project/setuptools/
+
+Documentation
+-------------
+
+The documentation_ can be found on Read The Docs.
+
+.. _documentation: https://wheel.readthedocs.io/
+
+Code of Conduct
+---------------
+
+Everyone interacting in the wheel project's codebases, issue trackers, chat
+rooms, and mailing lists is expected to follow the `PSF Code of Conduct`_.
+

+    3. The pyver from the egg-info data should be ignored, as it is
+       constructed from the version of Python used to build the installer,
+       which is irrelevant - the installer filename is correct here (even to
+       the point that when it's not there, any version is implied).
+    4. The architecture must be taken from the installer filename, as it is
+       not included in the egg-info data.
+    5. Architecture-neutral installers still have an architecture because the

+IMPORTANT: DO NOT IMPORT THIS MODULE DIRECTLY.
+THIS IS ONLY KEPT IN PLACE FOR BACKWARDS COMPATIBILITY WITH
+setuptools.command.bdist_wheel.
+
+This module contains function to analyse dynamic library
+headers to extract system information
+
+Currently only for MacOSX
+
+Library file on macosx system starts with Mach-O or Fat field.
+This can be distinguish by first 32 bites and it is called magic number.
+Proper value of magic number is with suffix _MAGIC. Suffix _CIGAM means
+reversed bytes order.
+Both fields can occur in two types: 32 and 64 bytes.
+
+FAT field inform that this library contains few version of library
+(typically for different types version). It contains
+information where Mach-O headers starts.
+
+Each section started with Mach-O header contains one library
+(So if file starts with this field it contains only one version).
+
+After filed Mach-O there are section fields.
+Each of them starts with two fields:
+cmd - magic number for this command
+cmdsize - total size occupied by this section information.
+
+In this case only sections LC_VERSION_MIN_MACOSX (for macosx 10.13 and earlier)
+and LC_BUILD_VERSION (for macosx 10.14 and newer) are interesting,
+because them contains information about minimal system version.
+
+Important remarks:
+- For fat files this implementation looks for maximum number version.
+  It not check if it is 32 or 64 and do not compare it with currently built package.
+  So it is possible to false report higher version that needed.
+- All structures signatures are taken form macosx header files.
+- I think that binary format will be more stable than `otool` output.
+  and if apple introduce some changes both implementation will need to be updated.
+- The system compile will set the deployment target no lower than
+  11.0 for arm64 builds. For "Universal 2" builds use the x86_64 deployment
+  target when the arm64 target is 11.0.

+A pathlib-compatible Zipfile object wrapper. Official backport of the standard library
+`Path object `_.
+
+
+Compatibility
+=============
+
+New features are introduced in this third-party library and later merged
+into CPython. The following table indicates which versions of this library
+were contributed to different versions in the standard library:
+
+.. list-table::

+    from ``setuptools.Command``.
+
+    When creating an :pep:`editable wheel <660>`, ``setuptools`` will try to evaluate
+    custom ``build`` subcommands using the following procedure:
+
+    1. ``setuptools`` will set the ``editable_mode`` attribute to ``True``
+    2. ``setuptools`` will execute the ``run()`` command.
+
+       .. important::
+          Subcommands **SHOULD** take advantage of ``editable_mode=True`` to adequate
+          its behaviour or perform optimisations.
+
+          For example, if a subcommand doesn't need to generate an extra file and
+          all it does is to copy a source file into the build directory,
+          ``run()`` **SHOULD** simply "early return".
+
+          Similarly, if the subcommand creates files that would be placed alongside
+          Python files in the final distribution, during an editable install
+          the command **SHOULD** generate these files "in place" (i.e. write them to
+          the original source directory, instead of using the build directory).
+          Note that ``get_output_mapping()`` should reflect that and include mappings
+          for "in place" builds accordingly.
+
+    3. ``setuptools`` use any knowledge it can derive from the return values of
+       ``get_outputs()`` and ``get_output_mapping()`` to create an editable wheel.
+       When relevant ``setuptools`` **MAY** attempt to use file links based on the value
+       of ``get_output_mapping()``. Alternatively, ``setuptools`` **MAY** attempt to use
+       :doc:`import hooks ` to redirect any attempt to import
+       to the directory with the original source code and other files built in place.
+
+    Please note that custom sub-commands **SHOULD NOT** rely on ``run()`` being
+    executed (or not) to provide correct return values for ``get_outputs()``,
+    ``get_output_mapping()`` or ``get_source_files()``. The ``get_*`` methods should
+    work independently of ``run()``.

+    A way of thinking about this is that the files saved under ``build_lib``
+    would be eventually copied to one of the directories in :obj:`site.PREFIXES`
+    upon installation.
+
+    A command that produces platform-independent files (e.g. compiling text templates

+
+        This leads to an ambiguous overall configuration. If you want to distribute this
+        package, please make sure that {importable!r} is explicitly added
+        to the `packages` configuration field.
+
+        Alternatively, you can also rely on setuptools' discovery methods
+        (for example by using `find_namespace_packages(...)`/`find_namespace:`
+        instead of `find_packages(...)`/`find:`).
+
+        You can read more about "package discovery" on setuptools documentation page:

+        If you don't want {importable!r} to be distributed and are
+        already explicitly excluding {importable!r} via
+        `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`,
+        you can try to use `exclude_package_data`, or `include-package-data=False` in
+        combination with a more fine grained `package-data` configuration.

+"""Utility functions to expand configuration directives or special values
+(such glob patterns).
+
+We can split the process of interpreting configuration files into 2 steps:
+
+1. The parsing the file contents from strings to value objects
+   that can be understand by Python (for example a string with a comma
+   separated list of keywords into an actual Python list of strings).
+
+2. The expansion (or post-processing) of these values according to the
+   semantics ``setuptools`` assign to them (for example a configuration field
+   with the ``file:`` directive should be expanded from a list of file paths to
+   a single string with the contents of those files concatenated)
+
+This module focus on the second step, and therefore allow sharing the expansion
+functions among several configuration file formats.

See the "External Dialects" list on the +:ref:`dialect_toplevel` page. + +.. _mssql_identity: + +Auto Increment Behavior / IDENTITY Columns +------------------------------------------ + +SQL Server provides so-called "auto incrementing" behavior using the +``IDENTITY`` construct, which can be placed on any single integer column in a +table. SQLAlchemy considers ``IDENTITY`` within its default "autoincrement" +behavior for an integer primary key column, described at +:paramref:`_schema.Column.autoincrement`. This means that by default, +the first integer primary key column in a :class:`_schema.Table` will be +considered to be the identity column - unless it is associated with a +:class:`.Sequence` - and will generate DDL as such:: + + from sqlalchemy import Table, MetaData, Column, Integer + + m = MetaData() + t = Table( + "t", + m, + Column("id", Integer, primary_key=True), + Column("x", Integer), + ) + m.create_all(engine) + +The above example will generate DDL as: + +.. sourcecode:: sql + + CREATE TABLE t ( + id INTEGER NOT NULL IDENTITY, + x INTEGER NULL, + PRIMARY KEY (id) + ) + +For the case where this default generation of ``IDENTITY`` is not desired, +specify ``False`` for the :paramref:`_schema.Column.autoincrement` flag, +on the first integer primary key column:: + + m = MetaData() + t = Table( + "t", + m, + Column("id", Integer, primary_key=True, autoincrement=False), + Column("x", Integer), + ) + m.create_all(engine) + +To add the ``IDENTITY`` keyword to a non-primary key column, specify +``True`` for the :paramref:`_schema.Column.autoincrement` flag on the desired +:class:`_schema.Column` object, and ensure that +:paramref:`_schema.Column.autoincrement` +is set to ``False`` on any integer primary key column:: + + m = MetaData() + t = Table( + "t", + m, + Column("id", Integer, primary_key=True, autoincrement=False), + Column("x", Integer, autoincrement=True), + ) + m.create_all(engine) + +.. versionchanged:: 1.4 Added :class:`_schema.Identity` construct + in a :class:`_schema.Column` to specify the start and increment + parameters of an IDENTITY. These replace + the use of the :class:`.Sequence` object in order to specify these values. + +.. deprecated:: 1.4 + + The ``mssql_identity_start`` and ``mssql_identity_increment`` parameters + to :class:`_schema.Column` are deprecated and should we replaced by + an :class:`_schema.Identity` object. Specifying both ways of configuring + an IDENTITY will result in a compile error. + These options are also no longer returned as part of the + ``dialect_options`` key in :meth:`_reflection.Inspector.get_columns`. + Use the information in the ``identity`` key instead. + +.. deprecated:: 1.3 + + The use of :class:`.Sequence` to specify IDENTITY characteristics is + deprecated and will be removed in a future release. Please use + the :class:`_schema.Identity` object parameters + :paramref:`_schema.Identity.start` and + :paramref:`_schema.Identity.increment`. + +.. versionchanged:: 1.4 Removed the ability to use a :class:`.Sequence` + object to modify IDENTITY characteristics. :class:`.Sequence` objects + now only manipulate true T-SQL SEQUENCE types. + +.. note:: + + There can only be one IDENTITY column on the table. When using + ``autoincrement=True`` to enable the IDENTITY keyword, SQLAlchemy does not + guard against multiple columns specifying the option simultaneously. The + SQL Server database will instead reject the ``CREATE TABLE`` statement. + +.. note:: + + An INSERT statement which attempts to provide a value for a column that is + marked with IDENTITY will be rejected by SQL Server. In order for the + value to be accepted, a session-level option "SET IDENTITY_INSERT" must be + enabled. The SQLAlchemy SQL Server dialect will perform this operation + automatically when using a core :class:`_expression.Insert` + construct; if the + execution specifies a value for the IDENTITY column, the "IDENTITY_INSERT" + option will be enabled for the span of that statement's invocation.However, + this scenario is not high performing and should not be relied upon for + normal use. If a table doesn't actually require IDENTITY behavior in its + integer primary key column, the keyword should be disabled when creating + the table by ensuring that ``autoincrement=False`` is set. + +Controlling "Start" and "Increment" +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Specific control over the "start" and "increment" values for +the ``IDENTITY`` generator are provided using the +:paramref:`_schema.Identity.start` and :paramref:`_schema.Identity.increment` +parameters passed to the :class:`_schema.Identity` object:: + + from sqlalchemy import Table, Integer, Column, Identity + + test = Table( + "test", + metadata, + Column( + "id", Integer, primary_key=True, Identity(start=100, increment=10) + ), + Column("name", String(20)), + ) + +The CREATE TABLE for the above :class:`_schema.Table` object would be: + +.. sourcecode:: sql + + CREATE TABLE test ( + id INTEGER NOT NULL IDENTITY(100,10) PRIMARY KEY, + name VARCHAR(20) NULL, + ) + +.. note:: + + The :class:`_schema.Identity` object supports many other parameter in + addition to ``start`` and ``increment``. These are not supported by + SQL Server and will be ignored when generating the CREATE TABLE ddl. + +.. versionchanged:: 1.3.19 The :class:`_schema.Identity` object is + now used to affect the + ``IDENTITY`` generator for a :class:`_schema.Column` under SQL Server. + Previously, the :class:`.Sequence` object was used. As SQL Server now + supports real sequences as a separate construct, :class:`.Sequence` will be + functional in the normal way starting from SQLAlchemy version 1.4. + + +Using IDENTITY with Non-Integer numeric types +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +SQL Server also allows ``IDENTITY`` to be used with ``NUMERIC`` columns. To +implement this pattern smoothly in SQLAlchemy, the primary datatype of the +column should remain as ``Integer``, however the underlying implementation +type deployed to the SQL Server database can be specified as ``Numeric`` using +:meth:`.TypeEngine.with_variant`:: + + from sqlalchemy import Column + from sqlalchemy import Integer + from sqlalchemy import Numeric + from sqlalchemy import String + from sqlalchemy.ext.declarative import declarative_base + + Base = declarative_base() + + + class TestTable(Base): + __tablename__ = "test" + id = Column( + Integer().with_variant(Numeric(10, 0), "mssql"), + primary_key=True, + autoincrement=True, + ) + name = Column(String) + +In the above example, ``Integer().with_variant()`` provides clear usage +information that accurately describes the intent of the code. The general +restriction that ``autoincrement`` only applies to ``Integer`` is established +at the metadata level and not at the per-dialect level. + +When using the above pattern, the primary key identifier that comes back from +the insertion of a row, which is also the value that would be assigned to an +ORM object such as ``TestTable`` above, will be an instance of ``Decimal()`` +and not ``int`` when using SQL Server. The numeric return type of the +:class:`_types.Numeric` type can be changed to return floats by passing False +to :paramref:`_types.Numeric.asdecimal`. To normalize the return type of the +above ``Numeric(10, 0)`` to return Python ints (which also support "long" +integer values in Python 3), use :class:`_types.TypeDecorator` as follows:: + + from sqlalchemy import TypeDecorator + + + class NumericAsInteger(TypeDecorator): + "normalize floating point return values into ints" + + impl = Numeric(10, 0, asdecimal=False) + cache_ok = True + + def process_result_value(self, value, dialect): + if value is not None: + value = int(value) + return value + + + class TestTable(Base): + __tablename__ = "test" + id = Column( + Integer().with_variant(NumericAsInteger, "mssql"), + primary_key=True, + autoincrement=True, + ) + name = Column(String) + +.. _mssql_insert_behavior: + +INSERT behavior +^^^^^^^^^^^^^^^^ + +Handling of the ``IDENTITY`` column at INSERT time involves two key +techniques. The most common is being able to fetch the "last inserted value" +for a given ``IDENTITY`` column, a process which SQLAlchemy performs +implicitly in many cases, most importantly within the ORM. + +The process for fetching this value has several variants: + +* In the vast majority of cases, RETURNING is used in conjunction with INSERT + statements on SQL Server in order to get newly generated primary key values: + + .. sourcecode:: sql + + INSERT INTO t (x) OUTPUT inserted.id VALUES (?) + + As of SQLAlchemy 2.0, the :ref:`engine_insertmanyvalues` feature is also + used by default to optimize many-row INSERT statements; for SQL Server + the feature takes place for both RETURNING and-non RETURNING + INSERT statements. + + .. versionchanged:: 2.0.10 The :ref:`engine_insertmanyvalues` feature for + SQL Server was temporarily disabled for SQLAlchemy version 2.0.9 due to + issues with row ordering. As of 2.0.10 the feature is re-enabled, with + special case handling for the unit of work's requirement for RETURNING to + be ordered. + +* When RETURNING is not available or has been disabled via + ``implicit_returning=False``, either the ``scope_identity()`` function or + the ``@@identity`` variable is used; behavior varies by backend: + + * when using PyODBC, the phrase ``; select scope_identity()`` will be + appended to the end of the INSERT statement; a second result set will be + fetched in order to receive the value. Given a table as:: + + t = Table( + "t", + metadata, + Column("id", Integer, primary_key=True), + Column("x", Integer), + implicit_returning=False, + ) + + an INSERT will look like: + + .. sourcecode:: sql + + INSERT INTO t (x) VALUES (?); select scope_identity() + + * Other dialects such as pymssql will call upon + ``SELECT scope_identity() AS lastrowid`` subsequent to an INSERT + statement. If the flag ``use_scope_identity=False`` is passed to + :func:`_sa.create_engine`, + the statement ``SELECT @@identity AS lastrowid`` + is used instead. + +A table that contains an ``IDENTITY`` column will prohibit an INSERT statement +that refers to the identity column explicitly. The SQLAlchemy dialect will +detect when an INSERT construct, created using a core +:func:`_expression.insert` +construct (not a plain string SQL), refers to the identity column, and +in this case will emit ``SET IDENTITY_INSERT ON`` prior to the insert +statement proceeding, and ``SET IDENTITY_INSERT OFF`` subsequent to the +execution. Given this example:: + + m = MetaData() + t = Table( + "t", m, Column("id", Integer, primary_key=True), Column("x", Integer) + ) + m.create_all(engine) + + with engine.begin() as conn: + conn.execute(t.insert(), {"id": 1, "x": 1}, {"id": 2, "x": 2}) + +The above column will be created with IDENTITY, however the INSERT statement +we emit is specifying explicit values. In the echo output we can see +how SQLAlchemy handles this: + +.. sourcecode:: sql + + CREATE TABLE t ( + id INTEGER NOT NULL IDENTITY(1,1), + x INTEGER NULL, + PRIMARY KEY (id) + ) + + COMMIT + SET IDENTITY_INSERT t ON + INSERT INTO t (id, x) VALUES (?, ?) + ((1, 1), (2, 2)) + SET IDENTITY_INSERT t OFF + COMMIT + + + +This is an auxiliary use case suitable for testing and bulk insert scenarios. + +SEQUENCE support +---------------- + +The :class:`.Sequence` object creates "real" sequences, i.e., +``CREATE SEQUENCE``: + +.. sourcecode:: pycon+sql + + >>> from sqlalchemy import Sequence + >>> from sqlalchemy.schema import CreateSequence + >>> from sqlalchemy.dialects import mssql + >>> print( + ... CreateSequence(Sequence("my_seq", start=1)).compile( + ... dialect=mssql.dialect() + ... ) + ... ) + {printsql}CREATE SEQUENCE my_seq START WITH 1 + +For integer primary key generation, SQL Server's ``IDENTITY`` construct should +generally be preferred vs. sequence. + +.. tip:: + + The default start value for T-SQL is ``-2**63`` instead of 1 as + in most other SQL databases. Users should explicitly set the + :paramref:`.Sequence.start` to 1 if that's the expected default:: + + seq = Sequence("my_sequence", start=1) + +.. versionadded:: 1.4 added SQL Server support for :class:`.Sequence` + +.. versionchanged:: 2.0 The SQL Server dialect will no longer implicitly + render "START WITH 1" for ``CREATE SEQUENCE``, which was the behavior + first implemented in version 1.4. + +MAX on VARCHAR / NVARCHAR +------------------------- + +SQL Server supports the special string "MAX" within the +:class:`_types.VARCHAR` and :class:`_types.NVARCHAR` datatypes, +to indicate "maximum length possible". The dialect currently handles this as +a length of "None" in the base type, rather than supplying a +dialect-specific version of these types, so that a base type +specified such as ``VARCHAR(None)`` can assume "unlengthed" behavior on +more than one backend without using dialect-specific types. + +To build a SQL Server VARCHAR or NVARCHAR with MAX length, use None:: + + my_table = Table( + "my_table", + metadata, + Column("my_data", VARCHAR(None)), + Column("my_n_data", NVARCHAR(None)), + ) + +Collation Support +----------------- + +Character collations are supported by the base string types, +specified by the string argument "collation":: + + from sqlalchemy import VARCHAR + + Column("login", VARCHAR(32, collation="Latin1_General_CI_AS")) + +When such a column is associated with a :class:`_schema.Table`, the +CREATE TABLE statement for this column will yield: + +.. sourcecode:: sql + + login VARCHAR(32) COLLATE Latin1_General_CI_AS NULL + +LIMIT/OFFSET Support +-------------------- + +MSSQL has added support for LIMIT / OFFSET as of SQL Server 2012, via the +"OFFSET n ROWS" and "FETCH NEXT n ROWS" clauses. SQLAlchemy supports these +syntaxes automatically if SQL Server 2012 or greater is detected. + +.. versionchanged:: 1.4 support added for SQL Server "OFFSET n ROWS" and + "FETCH NEXT n ROWS" syntax. + +For statements that specify only LIMIT and no OFFSET, all versions of SQL +Server support the TOP keyword. This syntax is used for all SQL Server +versions when no OFFSET clause is present. A statement such as:: + + select(some_table).limit(5) + +will render similarly to: + +.. sourcecode:: sql + + SELECT TOP 5 col1, col2.. FROM table + +For versions of SQL Server prior to SQL Server 2012, a statement that uses +LIMIT and OFFSET, or just OFFSET alone, will be rendered using the +``ROW_NUMBER()`` window function. A statement such as:: + + select(some_table).order_by(some_table.c.col3).limit(5).offset(10) + +will render similarly to: + +.. sourcecode:: sql + + SELECT anon_1.col1, anon_1.col2 FROM (SELECT col1, col2, + ROW_NUMBER() OVER (ORDER BY col3) AS + mssql_rn FROM table WHERE t.x = :x_1) AS + anon_1 WHERE mssql_rn > :param_1 AND mssql_rn <= :param_2 + :param_1 + +Note that when using LIMIT and/or OFFSET, whether using the older +or newer SQL Server syntaxes, the statement must have an ORDER BY as well, +else a :class:`.CompileError` is raised. + +.. _mssql_comment_support: + +DDL Comment Support +-------------------- + +Comment support, which includes DDL rendering for attributes such as +:paramref:`_schema.Table.comment` and :paramref:`_schema.Column.comment`, as +well as the ability to reflect these comments, is supported assuming a +supported version of SQL Server is in use. If a non-supported version such as +Azure Synapse is detected at first-connect time (based on the presence +of the ``fn_listextendedproperty`` SQL function), comment support including +rendering and table-comment reflection is disabled, as both features rely upon +SQL Server stored procedures and functions that are not available on all +backend types. + +To force comment support to be on or off, bypassing autodetection, set the +parameter ``supports_comments`` within :func:`_sa.create_engine`:: + + e = create_engine("mssql+pyodbc://u:p@dsn", supports_comments=False) + +.. versionadded:: 2.0 Added support for table and column comments for + the SQL Server dialect, including DDL generation and reflection. + +.. _mssql_isolation_level: + +Transaction Isolation Level +--------------------------- + +All SQL Server dialects support setting of transaction isolation level +both via a dialect-specific parameter +:paramref:`_sa.create_engine.isolation_level` +accepted by :func:`_sa.create_engine`, +as well as the :paramref:`.Connection.execution_options.isolation_level` +argument as passed to +:meth:`_engine.Connection.execution_options`. +This feature works by issuing the +command ``SET TRANSACTION ISOLATION LEVEL `` for +each new connection. + +To set isolation level using :func:`_sa.create_engine`:: + + engine = create_engine( + "mssql+pyodbc://scott:tiger@ms_2008", isolation_level="REPEATABLE READ" + ) + +To set using per-connection execution options:: + + connection = engine.connect() + connection = connection.execution_options(isolation_level="READ COMMITTED") + +Valid values for ``isolation_level`` include: + +* ``AUTOCOMMIT`` - pyodbc / pymssql-specific +* ``READ COMMITTED`` +* ``READ UNCOMMITTED`` +* ``REPEATABLE READ`` +* ``SERIALIZABLE`` +* ``SNAPSHOT`` - specific to SQL Server + +There are also more options for isolation level configurations, such as +"sub-engine" objects linked to a main :class:`_engine.Engine` which each apply +different isolation level settings. See the discussion at +:ref:`dbapi_autocommit` for background. + +.. seealso:: + + :ref:`dbapi_autocommit` + +.. _mssql_reset_on_return: + +Temporary Table / Resource Reset for Connection Pooling +------------------------------------------------------- + +The :class:`.QueuePool` connection pool implementation used +by the SQLAlchemy :class:`.Engine` object includes +:ref:`reset on return ` behavior that will invoke +the DBAPI ``.rollback()`` method when connections are returned to the pool. +While this rollback will clear out the immediate state used by the previous +transaction, it does not cover a wider range of session-level state, including +temporary tables as well as other server state such as prepared statement +handles and statement caches. An undocumented SQL Server procedure known +as ``sp_reset_connection`` is known to be a workaround for this issue which +will reset most of the session state that builds up on a connection, including +temporary tables. + +To install ``sp_reset_connection`` as the means of performing reset-on-return, +the :meth:`.PoolEvents.reset` event hook may be used, as demonstrated in the +example below. The :paramref:`_sa.create_engine.pool_reset_on_return` parameter +is set to ``None`` so that the custom scheme can replace the default behavior +completely. The custom hook implementation calls ``.rollback()`` in any case, +as it's usually important that the DBAPI's own tracking of commit/rollback +will remain consistent with the state of the transaction:: + + from sqlalchemy import create_engine + from sqlalchemy import event + + mssql_engine = create_engine( + "mssql+pyodbc://scott:tiger^5HHH@mssql2017:1433/test?driver=ODBC+Driver+17+for+SQL+Server", + # disable default reset-on-return scheme + pool_reset_on_return=None, + ) + + + @event.listens_for(mssql_engine, "reset") + def _reset_mssql(dbapi_connection, connection_record, reset_state): + if not reset_state.terminate_only: + dbapi_connection.execute("{call sys.sp_reset_connection}") + + # so that the DBAPI itself knows that the connection has been + # reset + dbapi_connection.rollback() + +.. versionchanged:: 2.0.0b3 Added additional state arguments to + the :meth:`.PoolEvents.reset` event and additionally ensured the event + is invoked for all "reset" occurrences, so that it's appropriate + as a place for custom "reset" handlers. Previous schemes which + use the :meth:`.PoolEvents.checkin` handler remain usable as well. + +.. seealso:: + + :ref:`pool_reset_on_return` - in the :ref:`pooling_toplevel` documentation + +Nullability +----------- +MSSQL has support for three levels of column nullability. The default +nullability allows nulls and is explicit in the CREATE TABLE +construct: + +.. sourcecode:: sql + + name VARCHAR(20) NULL + +If ``nullable=None`` is specified then no specification is made. In +other words the database's configured default is used. This will +render: + +.. sourcecode:: sql + + name VARCHAR(20) + +If ``nullable`` is ``True`` or ``False`` then the column will be +``NULL`` or ``NOT NULL`` respectively. + +Date / Time Handling +-------------------- +DATE and TIME are supported. Bind parameters are converted +to datetime.datetime() objects as required by most MSSQL drivers, +and results are processed from strings if needed. +The DATE and TIME types are not available for MSSQL 2005 and +previous - if a server version below 2008 is detected, DDL +for these types will be issued as DATETIME. + +.. _mssql_large_type_deprecation: + +Large Text/Binary Type Deprecation +---------------------------------- + +Per +`SQL Server 2012/2014 Documentation `_, +the ``NTEXT``, ``TEXT`` and ``IMAGE`` datatypes are to be removed from SQL +Server in a future release. SQLAlchemy normally relates these types to the +:class:`.UnicodeText`, :class:`_expression.TextClause` and +:class:`.LargeBinary` datatypes. + +In order to accommodate this change, a new flag ``deprecate_large_types`` +is added to the dialect, which will be automatically set based on detection +of the server version in use, if not otherwise set by the user. The +behavior of this flag is as follows: + +* When this flag is ``True``, the :class:`.UnicodeText`, + :class:`_expression.TextClause` and + :class:`.LargeBinary` datatypes, when used to render DDL, will render the + types ``NVARCHAR(max)``, ``VARCHAR(max)``, and ``VARBINARY(max)``, + respectively. This is a new behavior as of the addition of this flag. + +* When this flag is ``False``, the :class:`.UnicodeText`, + :class:`_expression.TextClause` and + :class:`.LargeBinary` datatypes, when used to render DDL, will render the + types ``NTEXT``, ``TEXT``, and ``IMAGE``, + respectively. This is the long-standing behavior of these types. + +* The flag begins with the value ``None``, before a database connection is + established. If the dialect is used to render DDL without the flag being + set, it is interpreted the same as ``False``. + +* On first connection, the dialect detects if SQL Server version 2012 or + greater is in use; if the flag is still at ``None``, it sets it to ``True`` + or ``False`` based on whether 2012 or greater is detected. + +* The flag can be set to either ``True`` or ``False`` when the dialect + is created, typically via :func:`_sa.create_engine`:: + + eng = create_engine( + "mssql+pymssql://user:pass@host/db", deprecate_large_types=True + ) + +* Complete control over whether the "old" or "new" types are rendered is + available in all SQLAlchemy versions by using the UPPERCASE type objects + instead: :class:`_types.NVARCHAR`, :class:`_types.VARCHAR`, + :class:`_types.VARBINARY`, :class:`_types.TEXT`, :class:`_mssql.NTEXT`, + :class:`_mssql.IMAGE` + will always remain fixed and always output exactly that + type. + +.. _multipart_schema_names: + +Multipart Schema Names +---------------------- + +SQL Server schemas sometimes require multiple parts to their "schema" +qualifier, that is, including the database name and owner name as separate +tokens, such as ``mydatabase.dbo.some_table``. These multipart names can be set +at once using the :paramref:`_schema.Table.schema` argument of +:class:`_schema.Table`:: + + Table( + "some_table", + metadata, + Column("q", String(50)), + schema="mydatabase.dbo", + ) + +When performing operations such as table or component reflection, a schema +argument that contains a dot will be split into separate +"database" and "owner" components in order to correctly query the SQL +Server information schema tables, as these two values are stored separately. +Additionally, when rendering the schema name for DDL or SQL, the two +components will be quoted separately for case sensitive names and other +special characters. Given an argument as below:: + + Table( + "some_table", + metadata, + Column("q", String(50)), + schema="MyDataBase.dbo", + ) + +The above schema would be rendered as ``[MyDataBase].dbo``, and also in +reflection, would be reflected using "dbo" as the owner and "MyDataBase" +as the database name. + +To control how the schema name is broken into database / owner, +specify brackets (which in SQL Server are quoting characters) in the name. +Below, the "owner" will be considered as ``MyDataBase.dbo`` and the +"database" will be None:: + + Table( + "some_table", + metadata, + Column("q", String(50)), + schema="[MyDataBase.dbo]", + ) + +To individually specify both database and owner name with special characters +or embedded dots, use two sets of brackets:: + + Table( + "some_table", + metadata, + Column("q", String(50)), + schema="[MyDataBase.Period].[MyOwner.Dot]", + ) + +.. versionchanged:: 1.2 the SQL Server dialect now treats brackets as + identifier delimiters splitting the schema into separate database + and owner tokens, to allow dots within either name itself. + +.. _legacy_schema_rendering: + +Legacy Schema Mode +------------------ + +Very old versions of the MSSQL dialect introduced the behavior such that a +schema-qualified table would be auto-aliased when used in a +SELECT statement; given a table:: + + account_table = Table( + "account", + metadata, + Column("id", Integer, primary_key=True), + Column("info", String(100)), + schema="customer_schema", + ) + +this legacy mode of rendering would assume that "customer_schema.account" +would not be accepted by all parts of the SQL statement, as illustrated +below: + +.. sourcecode:: pycon+sql + + >>> eng = create_engine("mssql+pymssql://mydsn", legacy_schema_aliasing=True) + >>> print(account_table.select().compile(eng)) + {printsql}SELECT account_1.id, account_1.info + FROM customer_schema.account AS account_1 + +This mode of behavior is now off by default, as it appears to have served +no purpose; however in the case that legacy applications rely upon it, +it is available using the ``legacy_schema_aliasing`` argument to +:func:`_sa.create_engine` as illustrated above. + +.. deprecated:: 1.4 + + The ``legacy_schema_aliasing`` flag is now + deprecated and will be removed in a future release. + +.. _mssql_indexes: + +Clustered Index Support +----------------------- + +The MSSQL dialect supports clustered indexes (and primary keys) via the +``mssql_clustered`` option. This option is available to :class:`.Index`, +:class:`.UniqueConstraint`. and :class:`.PrimaryKeyConstraint`. +For indexes this option can be combined with the ``mssql_columnstore`` one +to create a clustered columnstore index. + +To generate a clustered index:: + + Index("my_index", table.c.x, mssql_clustered=True) + +which renders the index as ``CREATE CLUSTERED INDEX my_index ON table (x)``. + +To generate a clustered primary key use:: + + Table( + "my_table", + metadata, + Column("x", ...), + Column("y", ...), + PrimaryKeyConstraint("x", "y", mssql_clustered=True), + ) + +which will render the table, for example, as: + +.. sourcecode:: sql + + CREATE TABLE my_table ( + x INTEGER NOT NULL, + y INTEGER NOT NULL, + PRIMARY KEY CLUSTERED (x, y) + ) + +Similarly, we can generate a clustered unique constraint using:: + + Table( + "my_table", + metadata, + Column("x", ...), + Column("y", ...), + PrimaryKeyConstraint("x"), + UniqueConstraint("y", mssql_clustered=True), + ) + +To explicitly request a non-clustered primary key (for example, when +a separate clustered index is desired), use:: + + Table( + "my_table", + metadata, + Column("x", ...), + Column("y", ...), + PrimaryKeyConstraint("x", "y", mssql_clustered=False), + ) + +which will render the table, for example, as: + +.. sourcecode:: sql + + CREATE TABLE my_table ( + x INTEGER NOT NULL, + y INTEGER NOT NULL, + PRIMARY KEY NONCLUSTERED (x, y) + ) + +Columnstore Index Support +------------------------- + +The MSSQL dialect supports columnstore indexes via the ``mssql_columnstore`` +option. This option is available to :class:`.Index`. It be combined with +the ``mssql_clustered`` option to create a clustered columnstore index. + +To generate a columnstore index:: + + Index("my_index", table.c.x, mssql_columnstore=True) + +which renders the index as ``CREATE COLUMNSTORE INDEX my_index ON table (x)``. + +To generate a clustered columnstore index provide no columns:: + + idx = Index("my_index", mssql_clustered=True, mssql_columnstore=True) + # required to associate the index with the table + table.append_constraint(idx) + +the above renders the index as +``CREATE CLUSTERED COLUMNSTORE INDEX my_index ON table``. + +.. versionadded:: 2.0.18 + +MSSQL-Specific Index Options +----------------------------- + +In addition to clustering, the MSSQL dialect supports other special options +for :class:`.Index`. + +INCLUDE +^^^^^^^ + +The ``mssql_include`` option renders INCLUDE(colname) for the given string +names:: + + Index("my_index", table.c.x, mssql_include=["y"]) + +would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)`` + +.. _mssql_index_where: + +Filtered Indexes +^^^^^^^^^^^^^^^^ + +The ``mssql_where`` option renders WHERE(condition) for the given string +names:: + + Index("my_index", table.c.x, mssql_where=table.c.x > 10) + +would render the index as ``CREATE INDEX my_index ON table (x) WHERE x > 10``. + +.. versionadded:: 1.3.4 + +Index ordering +^^^^^^^^^^^^^^ + +Index ordering is available via functional expressions, such as:: + + Index("my_index", table.c.x.desc()) + +would render the index as ``CREATE INDEX my_index ON table (x DESC)`` + +.. seealso:: + + :ref:`schema_indexes_functional` + +Compatibility Levels +-------------------- +MSSQL supports the notion of setting compatibility levels at the +database level. This allows, for instance, to run a database that +is compatible with SQL2000 while running on a SQL2005 database +server. ``server_version_info`` will always return the database +server version information (in this case SQL2005) and not the +compatibility level information. Because of this, if running under +a backwards compatibility mode SQLAlchemy may attempt to use T-SQL +statements that are unable to be parsed by the database server. + +.. _mssql_triggers: + +Triggers +-------- + +SQLAlchemy by default uses OUTPUT INSERTED to get at newly +generated primary key values via IDENTITY columns or other +server side defaults. MS-SQL does not +allow the usage of OUTPUT INSERTED on tables that have triggers. +To disable the usage of OUTPUT INSERTED on a per-table basis, +specify ``implicit_returning=False`` for each :class:`_schema.Table` +which has triggers:: + + Table( + "mytable", + metadata, + Column("id", Integer, primary_key=True), + # ..., + implicit_returning=False, + ) + +Declarative form:: + + class MyClass(Base): + # ... + __table_args__ = {"implicit_returning": False} + +.. _mssql_rowcount_versioning: + +Rowcount Support / ORM Versioning +--------------------------------- + +The SQL Server drivers may have limited ability to return the number +of rows updated from an UPDATE or DELETE statement. + +As of this writing, the PyODBC driver is not able to return a rowcount when +OUTPUT INSERTED is used. Previous versions of SQLAlchemy therefore had +limitations for features such as the "ORM Versioning" feature that relies upon +accurate rowcounts in order to match version numbers with matched rows. + +SQLAlchemy 2.0 now retrieves the "rowcount" manually for these particular use +cases based on counting the rows that arrived back within RETURNING; so while +the driver still has this limitation, the ORM Versioning feature is no longer +impacted by it. As of SQLAlchemy 2.0.5, ORM versioning has been fully +re-enabled for the pyodbc driver. + +.. versionchanged:: 2.0.5 ORM versioning support is restored for the pyodbc + driver. Previously, a warning would be emitted during ORM flush that + versioning was not supported. + + +Enabling Snapshot Isolation +--------------------------- + +SQL Server has a default transaction +isolation mode that locks entire tables, and causes even mildly concurrent +applications to have long held locks and frequent deadlocks. +Enabling snapshot isolation for the database as a whole is recommended +for modern levels of concurrency support. This is accomplished via the +following ALTER DATABASE commands executed at the SQL prompt: + +.. sourcecode:: sql + + ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON + + ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON + +Background on SQL Server snapshot isolation is available at +https://msdn.microsoft.com/en-us/library/ms175095.aspx. + +""" #

The application then specifies the name +of this datasource, which encompasses details such as the specific ODBC driver +in use as well as the network address of the database. Assuming a datasource +is configured on the client, a basic DSN-based connection looks like:: + + engine = create_engine("mssql+pyodbc://scott:tiger@some_dsn") + +Which above, will pass the following connection string to PyODBC: + +.. sourcecode:: text + + DSN=some_dsn;UID=scott;PWD=tiger + +If the username and password are omitted, the DSN form will also add +the ``Trusted_Connection=yes`` directive to the ODBC string. + +Hostname Connections +^^^^^^^^^^^^^^^^^^^^ + +Hostname-based connections are also supported by pyodbc. These are often +easier to use than a DSN and have the additional advantage that the specific +database name to connect towards may be specified locally in the URL, rather +than it being fixed as part of a datasource configuration. + +When using a hostname connection, the driver name must also be specified in the +query parameters of the URL. As these names usually have spaces in them, the +name must be URL encoded which means using plus signs for spaces:: + + engine = create_engine( + "mssql+pyodbc://scott:tiger@myhost:port/databasename?driver=ODBC+Driver+17+for+SQL+Server" + ) + +The ``driver`` keyword is significant to the pyodbc dialect and must be +specified in lowercase. + +Any other names passed in the query string are passed through in the pyodbc +connect string, such as ``authentication``, ``TrustServerCertificate``, etc. +Multiple keyword arguments must be separated by an ampersand (``&``); these +will be translated to semicolons when the pyodbc connect string is generated +internally:: + + e = create_engine( + "mssql+pyodbc://scott:tiger@mssql2017:1433/test?" + "driver=ODBC+Driver+18+for+SQL+Server&TrustServerCertificate=yes" + "&authentication=ActiveDirectoryIntegrated" + ) + +The equivalent URL can be constructed using :class:`_sa.engine.URL`:: + + from sqlalchemy.engine import URL + + connection_url = URL.create( + "mssql+pyodbc", + username="scott", + password="tiger", + host="mssql2017", + port=1433, + database="test", + query={ + "driver": "ODBC Driver 18 for SQL Server", + "TrustServerCertificate": "yes", + "authentication": "ActiveDirectoryIntegrated", + }, + ) + +Pass through exact Pyodbc string +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +A PyODBC connection string can also be sent in pyodbc's format directly, as +specified in `the PyODBC documentation +`_, +using the parameter ``odbc_connect``. A :class:`_sa.engine.URL` object +can help make this easier:: + + from sqlalchemy.engine import URL + + connection_string = "DRIVER={SQL Server Native Client 10.0};SERVER=dagger;DATABASE=test;UID=user;PWD=password" + connection_url = URL.create( + "mssql+pyodbc", query={"odbc_connect": connection_string} + ) + + engine = create_engine(connection_url) + +.. _mssql_pyodbc_access_tokens: + +Connecting to databases with access tokens +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Some database servers are set up to only accept access tokens for login. For +example, SQL Server allows the use of Azure Active Directory tokens to connect +to databases. This requires creating a credential object using the +``azure-identity`` library. More information about the authentication step can be +found in `Microsoft's documentation +`_. + +After getting an engine, the credentials need to be sent to ``pyodbc.connect`` +each time a connection is requested. One way to do this is to set up an event +listener on the engine that adds the credential token to the dialect's connect +call. This is discussed more generally in :ref:`engines_dynamic_tokens`. For +SQL Server in particular, this is passed as an ODBC connection attribute with +a data structure `described by Microsoft +`_. + +The following code snippet will create an engine that connects to an Azure SQL +database using Azure credentials:: + + import struct + from sqlalchemy import create_engine, event + from sqlalchemy.engine.url import URL + from azure import identity + + # Connection option for access tokens, as defined in msodbcsql.h + SQL_COPT_SS_ACCESS_TOKEN = 1256 + TOKEN_URL = "https://database.windows.net/" # The token URL for any Azure SQL database + + connection_string = "mssql+pyodbc://@my-server.database.windows.net/myDb?driver=ODBC+Driver+17+for+SQL+Server" + + engine = create_engine(connection_string) + + azure_credentials = identity.DefaultAzureCredential() + + + @event.listens_for(engine, "do_connect") + def provide_token(dialect, conn_rec, cargs, cparams): + # remove the "Trusted_Connection" parameter that SQLAlchemy adds + cargs[0] = cargs[0].replace(";Trusted_Connection=Yes", "") + + # create token credential + raw_token = azure_credentials.get_token(TOKEN_URL).token.encode( + "utf-16-le" + ) + token_struct = struct.pack( + f"`_, + stating that a connection string when using an access token must not contain + ``UID``, ``PWD``, ``Authentication`` or ``Trusted_Connection`` parameters. + +.. _azure_synapse_ignore_no_transaction_on_rollback: + +Avoiding transaction-related exceptions on Azure Synapse Analytics +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Azure Synapse Analytics has a significant difference in its transaction +handling compared to plain SQL Server; in some cases an error within a Synapse +transaction can cause it to be arbitrarily terminated on the server side, which +then causes the DBAPI ``.rollback()`` method (as well as ``.commit()``) to +fail. The issue prevents the usual DBAPI contract of allowing ``.rollback()`` +to pass silently if no transaction is present as the driver does not expect +this condition. The symptom of this failure is an exception with a message +resembling 'No corresponding transaction found. (111214)' when attempting to +emit a ``.rollback()`` after an operation had a failure of some kind. + +This specific case can be handled by passing ``ignore_no_transaction_on_rollback=True`` to +the SQL Server dialect via the :func:`_sa.create_engine` function as follows:: + + engine = create_engine( + connection_url, ignore_no_transaction_on_rollback=True + ) + +Using the above parameter, the dialect will catch ``ProgrammingError`` +exceptions raised during ``connection.rollback()`` and emit a warning +if the error message contains code ``111214``, however will not raise +an exception. + +.. versionadded:: 1.4.40 Added the + ``ignore_no_transaction_on_rollback=True`` parameter. + +Enable autocommit for Azure SQL Data Warehouse (DW) connections +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Azure SQL Data Warehouse does not support transactions, +and that can cause problems with SQLAlchemy's "autobegin" (and implicit +commit/rollback) behavior. We can avoid these problems by enabling autocommit +at both the pyodbc and engine levels:: + + connection_url = sa.engine.URL.create( + "mssql+pyodbc", + username="scott", + password="tiger", + host="dw.azure.example.com", + database="mydb", + query={ + "driver": "ODBC Driver 17 for SQL Server", + "autocommit": "True", + }, + ) + + engine = create_engine(connection_url).execution_options( + isolation_level="AUTOCOMMIT" + ) + +Avoiding sending large string parameters as TEXT/NTEXT +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +By default, for historical reasons, Microsoft's ODBC drivers for SQL Server +send long string parameters (greater than 4000 SBCS characters or 2000 Unicode +characters) as TEXT/NTEXT values. TEXT and NTEXT have been deprecated for many +years and are starting to cause compatibility issues with newer versions of +SQL_Server/Azure. For example, see `this +issue `_. + +Starting with ODBC Driver 18 for SQL Server we can override the legacy +behavior and pass long strings as varchar(max)/nvarchar(max) using the +``LongAsMax=Yes`` connection string parameter:: + + connection_url = sa.engine.URL.create( + "mssql+pyodbc", + username="scott", + password="tiger", + host="mssqlserver.example.com", + database="mydb", + query={ + "driver": "ODBC Driver 18 for SQL Server", + "LongAsMax": "Yes", + }, + ) + +Pyodbc Pooling / connection close behavior +------------------------------------------ + +PyODBC uses internal `pooling +`_ by +default, which means connections will be longer lived than they are within +SQLAlchemy itself. As SQLAlchemy has its own pooling behavior, it is often +preferable to disable this behavior. This behavior can only be disabled +globally at the PyODBC module level, **before** any connections are made:: + + import pyodbc + + pyodbc.pooling = False + + # don't use the engine before pooling is set to False + engine = create_engine("mssql+pyodbc://user:pass@dsn") + +If this variable is left at its default value of ``True``, **the application +will continue to maintain active database connections**, even when the +SQLAlchemy engine itself fully discards a connection or if the engine is +disposed. + +.. seealso:: + + `pooling `_ - + in the PyODBC documentation. + +Driver / Unicode Support +------------------------- + +PyODBC works best with Microsoft ODBC drivers, particularly in the area +of Unicode support on both Python 2 and Python 3. + +Using the FreeTDS ODBC drivers on Linux or OSX with PyODBC is **not** +recommended; there have been historically many Unicode-related issues +in this area, including before Microsoft offered ODBC drivers for Linux +and OSX. Now that Microsoft offers drivers for all platforms, for +PyODBC support these are recommended. FreeTDS remains relevant for +non-ODBC drivers such as pymssql where it works very well. + + +Rowcount Support +---------------- + +Previous limitations with the SQLAlchemy ORM's "versioned rows" feature with +Pyodbc have been resolved as of SQLAlchemy 2.0.5. See the notes at +:ref:`mssql_rowcount_versioning`. + +.. _mssql_pyodbc_fastexecutemany: + +Fast Executemany Mode +--------------------- + +The PyODBC driver includes support for a "fast executemany" mode of execution +which greatly reduces round trips for a DBAPI ``executemany()`` call when using +Microsoft ODBC drivers, for **limited size batches that fit in memory**. The +feature is enabled by setting the attribute ``.fast_executemany`` on the DBAPI +cursor when an executemany call is to be used. The SQLAlchemy PyODBC SQL +Server dialect supports this parameter by passing the +``fast_executemany`` parameter to +:func:`_sa.create_engine` , when using the **Microsoft ODBC driver only**:: + + engine = create_engine( + "mssql+pyodbc://scott:tiger@mssql2017:1433/test?driver=ODBC+Driver+17+for+SQL+Server", + fast_executemany=True, + ) + +.. versionchanged:: 2.0.9 - the ``fast_executemany`` parameter now has its + intended effect of this PyODBC feature taking effect for all INSERT + statements that are executed with multiple parameter sets, which don't + include RETURNING.

See that method for usage examples. + +.. versionchanged:: 2.0 The mssql+pyodbc dialect now defaults to using + ``use_setinputsizes=True`` for all statement executions with the exception of + cursor.executemany() calls when fast_executemany=True.

MariaDB + :normal_support: 5.6+ / 10+ + :best_effort: 5.0.2+ / 5.0.2+ + +Supported Versions and Features +------------------------------- + +SQLAlchemy supports MySQL starting with version 5.0.2 through modern releases, +as well as all modern versions of MariaDB. See the official MySQL +documentation for detailed information about features supported in any given +server release. + +.. versionchanged:: 1.4 minimum MySQL version supported is now 5.0.2. + +MariaDB Support +~~~~~~~~~~~~~~~ + +The MariaDB variant of MySQL retains fundamental compatibility with MySQL's +protocols however the development of these two products continues to diverge. +Within the realm of SQLAlchemy, the two databases have a small number of +syntactical and behavioral differences that SQLAlchemy accommodates automatically. +To connect to a MariaDB database, no changes to the database URL are required:: + + + engine = create_engine( + "mysql+pymysql://user:pass@some_mariadb/dbname?charset=utf8mb4" + ) + +Upon first connect, the SQLAlchemy dialect employs a +server version detection scheme that determines if the +backing database reports as MariaDB. Based on this flag, the dialect +can make different choices in those of areas where its behavior +must be different. + +.. _mysql_mariadb_only_mode: + +MariaDB-Only Mode +~~~~~~~~~~~~~~~~~ + +The dialect also supports an **optional** "MariaDB-only" mode of connection, which may be +useful for the case where an application makes use of MariaDB-specific features +and is not compatible with a MySQL database. To use this mode of operation, +replace the "mysql" token in the above URL with "mariadb":: + + engine = create_engine( + "mariadb+pymysql://user:pass@some_mariadb/dbname?charset=utf8mb4" + ) + +The above engine, upon first connect, will raise an error if the server version +detection detects that the backing database is not MariaDB. + +When using an engine with ``"mariadb"`` as the dialect name, **all mysql-specific options +that include the name "mysql" in them are now named with "mariadb"**. This means +options like ``mysql_engine`` should be named ``mariadb_engine``, etc. Both +"mysql" and "mariadb" options can be used simultaneously for applications that +use URLs with both "mysql" and "mariadb" dialects:: + + my_table = Table( + "mytable", + metadata, + Column("id", Integer, primary_key=True), + Column("textdata", String(50)), + mariadb_engine="InnoDB", + mysql_engine="InnoDB", + ) + + Index( + "textdata_ix", + my_table.c.textdata, + mysql_prefix="FULLTEXT", + mariadb_prefix="FULLTEXT", + ) + +Similar behavior will occur when the above structures are reflected, i.e. the +"mariadb" prefix will be present in the option names when the database URL +is based on the "mariadb" name. + +.. versionadded:: 1.4 Added "mariadb" dialect name supporting "MariaDB-only mode" + for the MySQL dialect. + +.. _mysql_connection_timeouts: + +Connection Timeouts and Disconnects +----------------------------------- + +MySQL / MariaDB feature an automatic connection close behavior, for connections that +have been idle for a fixed period of time, defaulting to eight hours. +To circumvent having this issue, use +the :paramref:`_sa.create_engine.pool_recycle` option which ensures that +a connection will be discarded and replaced with a new one if it has been +present in the pool for a fixed number of seconds:: + + engine = create_engine("mysql+mysqldb://...", pool_recycle=3600) + +For more comprehensive disconnect detection of pooled connections, including +accommodation of server restarts and network issues, a pre-ping approach may +be employed. See :ref:`pool_disconnects` for current approaches. + +.. seealso:: + + :ref:`pool_disconnects` - Background on several techniques for dealing + with timed out connections as well as database restarts. + +.. _mysql_storage_engines: + +CREATE TABLE arguments including Storage Engines +------------------------------------------------ + +Both MySQL's and MariaDB's CREATE TABLE syntax includes a wide array of special options, +including ``ENGINE``, ``CHARSET``, ``MAX_ROWS``, ``ROW_FORMAT``, +``INSERT_METHOD``, and many more. +To accommodate the rendering of these arguments, specify the form +``mysql_argument_name="value"``. For example, to specify a table with +``ENGINE`` of ``InnoDB``, ``CHARSET`` of ``utf8mb4``, and ``KEY_BLOCK_SIZE`` +of ``1024``:: + + Table( + "mytable", + metadata, + Column("data", String(32)), + mysql_engine="InnoDB", + mysql_charset="utf8mb4", + mysql_key_block_size="1024", + ) + +When supporting :ref:`mysql_mariadb_only_mode` mode, similar keys against +the "mariadb" prefix must be included as well. The values can of course +vary independently so that different settings on MySQL vs. MariaDB may +be maintained:: + + # support both "mysql" and "mariadb-only" engine URLs + + Table( + "mytable", + metadata, + Column("data", String(32)), + mysql_engine="InnoDB", + mariadb_engine="InnoDB", + mysql_charset="utf8mb4", + mariadb_charset="utf8", + mysql_key_block_size="1024", + mariadb_key_block_size="1024", + ) + +The MySQL / MariaDB dialects will normally transfer any keyword specified as +``mysql_keyword_name`` to be rendered as ``KEYWORD_NAME`` in the +``CREATE TABLE`` statement. A handful of these names will render with a space +instead of an underscore; to support this, the MySQL dialect has awareness of +these particular names, which include ``DATA DIRECTORY`` +(e.g. ``mysql_data_directory``), ``CHARACTER SET`` (e.g. +``mysql_character_set``) and ``INDEX DIRECTORY`` (e.g. +``mysql_index_directory``). + +The most common argument is ``mysql_engine``, which refers to the storage +engine for the table. Historically, MySQL server installations would default +to ``MyISAM`` for this value, although newer versions may be defaulting +to ``InnoDB``. The ``InnoDB`` engine is typically preferred for its support +of transactions and foreign keys. + +A :class:`_schema.Table` +that is created in a MySQL / MariaDB database with a storage engine +of ``MyISAM`` will be essentially non-transactional, meaning any +INSERT/UPDATE/DELETE statement referring to this table will be invoked as +autocommit. It also will have no support for foreign key constraints; while +the ``CREATE TABLE`` statement accepts foreign key options, when using the +``MyISAM`` storage engine these arguments are discarded. Reflecting such a +table will also produce no foreign key constraint information. + +For fully atomic transactions as well as support for foreign key +constraints, all participating ``CREATE TABLE`` statements must specify a +transactional engine, which in the vast majority of cases is ``InnoDB``. + +Partitioning can similarly be specified using similar options. +In the example below the create table will specify ``PARTITION_BY``, +``PARTITIONS``, ``SUBPARTITIONS`` and ``SUBPARTITION_BY``:: + + # can also use mariadb_* prefix + Table( + "testtable", + MetaData(), + Column("id", Integer(), primary_key=True, autoincrement=True), + Column("other_id", Integer(), primary_key=True, autoincrement=False), + mysql_partitions="2", + mysql_partition_by="KEY(other_id)", + mysql_subpartition_by="HASH(some_expr)", + mysql_subpartitions="2", + ) + +This will render: + +.. sourcecode:: sql + + CREATE TABLE testtable ( + id INTEGER NOT NULL AUTO_INCREMENT, + other_id INTEGER NOT NULL, + PRIMARY KEY (id, other_id) + )PARTITION BY KEY(other_id) PARTITIONS 2 SUBPARTITION BY HASH(some_expr) SUBPARTITIONS 2 + +Case Sensitivity and Table Reflection +------------------------------------- + +Both MySQL and MariaDB have inconsistent support for case-sensitive identifier +names, basing support on specific details of the underlying +operating system. However, it has been observed that no matter +what case sensitivity behavior is present, the names of tables in +foreign key declarations are *always* received from the database +as all-lower case, making it impossible to accurately reflect a +schema where inter-related tables use mixed-case identifier names. + +Therefore it is strongly advised that table names be declared as +all lower case both within SQLAlchemy as well as on the MySQL / MariaDB +database itself, especially if database reflection features are +to be used. + +.. _mysql_isolation_level: + +Transaction Isolation Level +--------------------------- + +All MySQL / MariaDB dialects support setting of transaction isolation level both via a +dialect-specific parameter :paramref:`_sa.create_engine.isolation_level` +accepted +by :func:`_sa.create_engine`, as well as the +:paramref:`.Connection.execution_options.isolation_level` argument as passed to +:meth:`_engine.Connection.execution_options`. +This feature works by issuing the +command ``SET SESSION TRANSACTION ISOLATION LEVEL `` for each new +connection. For the special AUTOCOMMIT isolation level, DBAPI-specific +techniques are used. + +To set isolation level using :func:`_sa.create_engine`:: + + engine = create_engine( + "mysql+mysqldb://scott:tiger@localhost/test", + isolation_level="READ UNCOMMITTED", + ) + +To set using per-connection execution options:: + + connection = engine.connect() + connection = connection.execution_options(isolation_level="READ COMMITTED") + +Valid values for ``isolation_level`` include: + +* ``READ COMMITTED`` +* ``READ UNCOMMITTED`` +* ``REPEATABLE READ`` +* ``SERIALIZABLE`` +* ``AUTOCOMMIT`` + +The special ``AUTOCOMMIT`` value makes use of the various "autocommit" +attributes provided by specific DBAPIs, and is currently supported by +MySQLdb, MySQL-Client, MySQL-Connector Python, and PyMySQL. Using it, +the database connection will return true for the value of +``SELECT @@autocommit;``. + +There are also more options for isolation level configurations, such as +"sub-engine" objects linked to a main :class:`_engine.Engine` which each apply +different isolation level settings. See the discussion at +:ref:`dbapi_autocommit` for background. + +.. seealso:: + + :ref:`dbapi_autocommit` + +AUTO_INCREMENT Behavior +----------------------- + +When creating tables, SQLAlchemy will automatically set ``AUTO_INCREMENT`` on +the first :class:`.Integer` primary key column which is not marked as a +foreign key:: + + >>> t = Table( + ... "mytable", metadata, Column("mytable_id", Integer, primary_key=True) + ... ) + >>> t.create() + CREATE TABLE mytable ( + id INTEGER NOT NULL AUTO_INCREMENT, + PRIMARY KEY (id) + ) + +You can disable this behavior by passing ``False`` to the +:paramref:`_schema.Column.autoincrement` argument of :class:`_schema.Column`. +This flag +can also be used to enable auto-increment on a secondary column in a +multi-column key for some storage engines:: + + Table( + "mytable", + metadata, + Column("gid", Integer, primary_key=True, autoincrement=False), + Column("id", Integer, primary_key=True), + ) + +.. _mysql_ss_cursors: + +Server Side Cursors +------------------- + +Server-side cursor support is available for the mysqlclient, PyMySQL, +mariadbconnector dialects and may also be available in others. This makes use +of either the "buffered=True/False" flag if available or by using a class such +as ``MySQLdb.cursors.SSCursor`` or ``pymysql.cursors.SSCursor`` internally. + + +Server side cursors are enabled on a per-statement basis by using the +:paramref:`.Connection.execution_options.stream_results` connection execution +option:: + + with engine.connect() as conn: + result = conn.execution_options(stream_results=True).execute( + text("select * from table") + ) + +Note that some kinds of SQL statements may not be supported with +server side cursors; generally, only SQL statements that return rows should be +used with this option. + +.. deprecated:: 1.4 The dialect-level server_side_cursors flag is deprecated + and will be removed in a future release. Please use the + :paramref:`_engine.Connection.stream_results` execution option for + unbuffered cursor support. + +.. seealso:: + + :ref:`engine_stream_results` + +.. _mysql_unicode: + +Unicode +------- + +Charset Selection +~~~~~~~~~~~~~~~~~ + +Most MySQL / MariaDB DBAPIs offer the option to set the client character set for +a connection. This is typically delivered using the ``charset`` parameter +in the URL, such as:: + + e = create_engine( + "mysql+pymysql://scott:tiger@localhost/test?charset=utf8mb4" + ) + +This charset is the **client character set** for the connection. Some +MySQL DBAPIs will default this to a value such as ``latin1``, and some +will make use of the ``default-character-set`` setting in the ``my.cnf`` +file as well. Documentation for the DBAPI in use should be consulted +for specific behavior. + +The encoding used for Unicode has traditionally been ``'utf8'``. However, for +MySQL versions 5.5.3 and MariaDB 5.5 on forward, a new MySQL-specific encoding +``'utf8mb4'`` has been introduced, and as of MySQL 8.0 a warning is emitted by +the server if plain ``utf8`` is specified within any server-side directives, +replaced with ``utf8mb3``. The rationale for this new encoding is due to the +fact that MySQL's legacy utf-8 encoding only supports codepoints up to three +bytes instead of four. Therefore, when communicating with a MySQL or MariaDB +database that includes codepoints more than three bytes in size, this new +charset is preferred, if supported by both the database as well as the client +DBAPI, as in:: + + e = create_engine( + "mysql+pymysql://scott:tiger@localhost/test?charset=utf8mb4" + ) + +All modern DBAPIs should support the ``utf8mb4`` charset. + +In order to use ``utf8mb4`` encoding for a schema that was created with legacy +``utf8``, changes to the MySQL/MariaDB schema and/or server configuration may be +required. + +.. seealso:: + + `The utf8mb4 Character Set \ + `_ - \ + in the MySQL documentation + +.. _mysql_binary_introducer: + +Dealing with Binary Data Warnings and Unicode +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +MySQL versions 5.6, 5.7 and later (not MariaDB at the time of this writing) now +emit a warning when attempting to pass binary data to the database, while a +character set encoding is also in place, when the binary data itself is not +valid for that encoding: + +.. sourcecode:: text + + default.py:509: Warning: (1300, "Invalid utf8mb4 character string: + 'F9876A'") + cursor.execute(statement, parameters) + +This warning is due to the fact that the MySQL client library is attempting to +interpret the binary string as a unicode object even if a datatype such +as :class:`.LargeBinary` is in use. To resolve this, the SQL statement requires +a binary "character set introducer" be present before any non-NULL value +that renders like this: + +.. sourcecode:: sql + + INSERT INTO table (data) VALUES (_binary %s) + +These character set introducers are provided by the DBAPI driver, assuming the +use of mysqlclient or PyMySQL (both of which are recommended). Add the query +string parameter ``binary_prefix=true`` to the URL to repair this warning:: + + # mysqlclient + engine = create_engine( + "mysql+mysqldb://scott:tiger@localhost/test?charset=utf8mb4&binary_prefix=true" + ) + + # PyMySQL + engine = create_engine( + "mysql+pymysql://scott:tiger@localhost/test?charset=utf8mb4&binary_prefix=true" + ) + +The ``binary_prefix`` flag may or may not be supported by other MySQL drivers. + +SQLAlchemy itself cannot render this ``_binary`` prefix reliably, as it does +not work with the NULL value, which is valid to be sent as a bound parameter. +As the MySQL driver renders parameters directly into the SQL string, it's the +most efficient place for this additional keyword to be passed. + +.. seealso:: + + `Character set introducers `_ - on the MySQL website + + +ANSI Quoting Style +------------------ + +MySQL / MariaDB feature two varieties of identifier "quoting style", one using +backticks and the other using quotes, e.g. ```some_identifier``` vs. +``"some_identifier"``. All MySQL dialects detect which version +is in use by checking the value of :ref:`sql_mode` when a connection is first +established with a particular :class:`_engine.Engine`. +This quoting style comes +into play when rendering table and column names as well as when reflecting +existing database structures. The detection is entirely automatic and +no special configuration is needed to use either quoting style. + + +.. _mysql_sql_mode: + +Changing the sql_mode +--------------------- + +MySQL supports operating in multiple +`Server SQL Modes `_ for +both Servers and Clients. To change the ``sql_mode`` for a given application, a +developer can leverage SQLAlchemy's Events system. + +In the following example, the event system is used to set the ``sql_mode`` on +the ``first_connect`` and ``connect`` events:: + + from sqlalchemy import create_engine, event + + eng = create_engine( + "mysql+mysqldb://scott:tiger@localhost/test", echo="debug" + ) + + + # `insert=True` will ensure this is the very first listener to run + @event.listens_for(eng, "connect", insert=True) + def connect(dbapi_connection, connection_record): + cursor = dbapi_connection.cursor() + cursor.execute("SET sql_mode = 'STRICT_ALL_TABLES'") + + + conn = eng.connect() + +In the example illustrated above, the "connect" event will invoke the "SET" +statement on the connection at the moment a particular DBAPI connection is +first created for a given Pool, before the connection is made available to the +connection pool. Additionally, because the function was registered with +``insert=True``, it will be prepended to the internal list of registered +functions. + + +MySQL / MariaDB SQL Extensions +------------------------------ + +Many of the MySQL / MariaDB SQL extensions are handled through SQLAlchemy's generic +function and operator support:: + + table.select(table.c.password == func.md5("plaintext")) + table.select(table.c.username.op("regexp")("^[a-d]")) + +And of course any valid SQL statement can be executed as a string as well. + +Some limited direct support for MySQL / MariaDB extensions to SQL is currently +available. + +* INSERT..ON DUPLICATE KEY UPDATE: See + :ref:`mysql_insert_on_duplicate_key_update` + +* SELECT pragma, use :meth:`_expression.Select.prefix_with` and + :meth:`_query.Query.prefix_with`:: + + select(...).prefix_with(["HIGH_PRIORITY", "SQL_SMALL_RESULT"]) + +* UPDATE with LIMIT:: + + update(...).with_dialect_options(mysql_limit=10, mariadb_limit=10) + +* DELETE + with LIMIT:: + + delete(...).with_dialect_options(mysql_limit=10, mariadb_limit=10) + + .. versionadded:: 2.0.37 Added delete with limit + +* optimizer hints, use :meth:`_expression.Select.prefix_with` and + :meth:`_query.Query.prefix_with`:: + + select(...).prefix_with("/*+ NO_RANGE_OPTIMIZATION(t4 PRIMARY) */") + +* index hints, use :meth:`_expression.Select.with_hint` and + :meth:`_query.Query.with_hint`:: + + select(...).with_hint(some_table, "USE INDEX xyz") + +* MATCH + operator support:: + + from sqlalchemy.dialects.mysql import match + + select(...).where(match(col1, col2, against="some expr").in_boolean_mode()) + + .. seealso:: + + :class:`_mysql.match` + +INSERT/DELETE...RETURNING +------------------------- + +The MariaDB dialect supports 10.5+'s ``INSERT..RETURNING`` and +``DELETE..RETURNING`` (10.0+) syntaxes. ``INSERT..RETURNING`` may be used +automatically in some cases in order to fetch newly generated identifiers in +place of the traditional approach of using ``cursor.lastrowid``, however +``cursor.lastrowid`` is currently still preferred for simple single-statement +cases for its better performance. + +To specify an explicit ``RETURNING`` clause, use the +:meth:`._UpdateBase.returning` method on a per-statement basis:: + + # INSERT..RETURNING + result = connection.execute( + table.insert().values(name="foo").returning(table.c.col1, table.c.col2) + ) + print(result.all()) + + # DELETE..RETURNING + result = connection.execute( + table.delete() + .where(table.c.name == "foo") + .returning(table.c.col1, table.c.col2) + ) + print(result.all()) + +.. versionadded:: 2.0 Added support for MariaDB RETURNING + +.. _mysql_insert_on_duplicate_key_update: + +INSERT...ON DUPLICATE KEY UPDATE (Upsert) +------------------------------------------ + +MySQL / MariaDB allow "upserts" (update or insert) +of rows into a table via the ``ON DUPLICATE KEY UPDATE`` clause of the +``INSERT`` statement. A candidate row will only be inserted if that row does +not match an existing primary or unique key in the table; otherwise, an UPDATE +will be performed. The statement allows for separate specification of the +values to INSERT versus the values for UPDATE. + +SQLAlchemy provides ``ON DUPLICATE KEY UPDATE`` support via the MySQL-specific +:func:`.mysql.insert()` function, which provides +the generative method :meth:`~.mysql.Insert.on_duplicate_key_update`: + +.. sourcecode:: pycon+sql + + >>> from sqlalchemy.dialects.mysql import insert + + >>> insert_stmt = insert(my_table).values( + ... id="some_existing_id", data="inserted value" + ... ) + + >>> on_duplicate_key_stmt = insert_stmt.on_duplicate_key_update( + ... data=insert_stmt.inserted.data, status="U" + ... ) + >>> print(on_duplicate_key_stmt) + {printsql}INSERT INTO my_table (id, data) VALUES (%s, %s) + ON DUPLICATE KEY UPDATE data = VALUES(data), status = %s + + +Unlike PostgreSQL's "ON CONFLICT" phrase, the "ON DUPLICATE KEY UPDATE" +phrase will always match on any primary key or unique key, and will always +perform an UPDATE if there's a match; there are no options for it to raise +an error or to skip performing an UPDATE. + +``ON DUPLICATE KEY UPDATE`` is used to perform an update of the already +existing row, using any combination of new values as well as values +from the proposed insertion. These values are normally specified using +keyword arguments passed to the +:meth:`_mysql.Insert.on_duplicate_key_update` +given column key values (usually the name of the column, unless it +specifies :paramref:`_schema.Column.key` +) as keys and literal or SQL expressions +as values: + +.. sourcecode:: pycon+sql + + >>> insert_stmt = insert(my_table).values( + ... id="some_existing_id", data="inserted value" + ... ) + + >>> on_duplicate_key_stmt = insert_stmt.on_duplicate_key_update( + ... data="some data", + ... updated_at=func.current_timestamp(), + ... ) + + >>> print(on_duplicate_key_stmt) + {printsql}INSERT INTO my_table (id, data) VALUES (%s, %s) + ON DUPLICATE KEY UPDATE data = %s, updated_at = CURRENT_TIMESTAMP + +In a manner similar to that of :meth:`.UpdateBase.values`, other parameter +forms are accepted, including a single dictionary: + +.. sourcecode:: pycon+sql + + >>> on_duplicate_key_stmt = insert_stmt.on_duplicate_key_update( + ... {"data": "some data", "updated_at": func.current_timestamp()}, + ... ) + +as well as a list of 2-tuples, which will automatically provide +a parameter-ordered UPDATE statement in a manner similar to that described +at :ref:`tutorial_parameter_ordered_updates`. Unlike the :class:`_expression.Update` +object, +no special flag is needed to specify the intent since the argument form is +this context is unambiguous: + +.. sourcecode:: pycon+sql + + >>> on_duplicate_key_stmt = insert_stmt.on_duplicate_key_update( + ... [ + ... ("data", "some data"), + ... ("updated_at", func.current_timestamp()), + ... ] + ... ) + + >>> print(on_duplicate_key_stmt) + {printsql}INSERT INTO my_table (id, data) VALUES (%s, %s) + ON DUPLICATE KEY UPDATE data = %s, updated_at = CURRENT_TIMESTAMP + +.. versionchanged:: 1.3 support for parameter-ordered UPDATE clause within + MySQL ON DUPLICATE KEY UPDATE + +.. warning:: + + The :meth:`_mysql.Insert.on_duplicate_key_update` + method does **not** take into + account Python-side default UPDATE values or generation functions, e.g. + e.g. those specified using :paramref:`_schema.Column.onupdate`. + These values will not be exercised for an ON DUPLICATE KEY style of UPDATE, + unless they are manually specified explicitly in the parameters. + + + +In order to refer to the proposed insertion row, the special alias +:attr:`_mysql.Insert.inserted` is available as an attribute on +the :class:`_mysql.Insert` object; this object is a +:class:`_expression.ColumnCollection` which contains all columns of the target +table: + +.. sourcecode:: pycon+sql + + >>> stmt = insert(my_table).values( + ... id="some_id", data="inserted value", author="jlh" + ... ) + + >>> do_update_stmt = stmt.on_duplicate_key_update( + ... data="updated value", author=stmt.inserted.author + ... ) + + >>> print(do_update_stmt) + {printsql}INSERT INTO my_table (id, data, author) VALUES (%s, %s, %s) + ON DUPLICATE KEY UPDATE data = %s, author = VALUES(author) + +When rendered, the "inserted" namespace will produce the expression +``VALUES()``. + +.. versionadded:: 1.2 Added support for MySQL ON DUPLICATE KEY UPDATE clause + + + +rowcount Support +---------------- + +SQLAlchemy standardizes the DBAPI ``cursor.rowcount`` attribute to be the +usual definition of "number of rows matched by an UPDATE or DELETE" statement. +This is in contradiction to the default setting on most MySQL DBAPI drivers, +which is "number of rows actually modified/deleted". For this reason, the +SQLAlchemy MySQL dialects always add the ``constants.CLIENT.FOUND_ROWS`` +flag, or whatever is equivalent for the target dialect, upon connection. +This setting is currently hardcoded. + +.. seealso:: + + :attr:`_engine.CursorResult.rowcount` + + +.. _mysql_indexes: + +MySQL / MariaDB- Specific Index Options +----------------------------------------- + +MySQL and MariaDB-specific extensions to the :class:`.Index` construct are available. + +Index Length +~~~~~~~~~~~~~ + +MySQL and MariaDB both provide an option to create index entries with a certain length, where +"length" refers to the number of characters or bytes in each value which will +become part of the index. SQLAlchemy provides this feature via the +``mysql_length`` and/or ``mariadb_length`` parameters:: + + Index("my_index", my_table.c.data, mysql_length=10, mariadb_length=10) + + Index("a_b_idx", my_table.c.a, my_table.c.b, mysql_length={"a": 4, "b": 9}) + + Index( + "a_b_idx", my_table.c.a, my_table.c.b, mariadb_length={"a": 4, "b": 9} + ) + +Prefix lengths are given in characters for nonbinary string types and in bytes +for binary string types. The value passed to the keyword argument *must* be +either an integer (and, thus, specify the same prefix length value for all +columns of the index) or a dict in which keys are column names and values are +prefix length values for corresponding columns. MySQL and MariaDB only allow a +length for a column of an index if it is for a CHAR, VARCHAR, TEXT, BINARY, +VARBINARY and BLOB. + +Index Prefixes +~~~~~~~~~~~~~~ + +MySQL storage engines permit you to specify an index prefix when creating +an index. SQLAlchemy provides this feature via the +``mysql_prefix`` parameter on :class:`.Index`:: + + Index("my_index", my_table.c.data, mysql_prefix="FULLTEXT") + +The value passed to the keyword argument will be simply passed through to the +underlying CREATE INDEX, so it *must* be a valid index prefix for your MySQL +storage engine. + +.. seealso:: + + `CREATE INDEX `_ - MySQL documentation + +Index Types +~~~~~~~~~~~~~ + +Some MySQL storage engines permit you to specify an index type when creating +an index or primary key constraint. SQLAlchemy provides this feature via the +``mysql_using`` parameter on :class:`.Index`:: + + Index( + "my_index", my_table.c.data, mysql_using="hash", mariadb_using="hash" + ) + +As well as the ``mysql_using`` parameter on :class:`.PrimaryKeyConstraint`:: + + PrimaryKeyConstraint("data", mysql_using="hash", mariadb_using="hash") + +The value passed to the keyword argument will be simply passed through to the +underlying CREATE INDEX or PRIMARY KEY clause, so it *must* be a valid index +type for your MySQL storage engine. + +More information can be found at: + +https://dev.mysql.com/doc/refman/5.0/en/create-index.html + +https://dev.mysql.com/doc/refman/5.0/en/create-table.html + +Index Parsers +~~~~~~~~~~~~~ + +CREATE FULLTEXT INDEX in MySQL also supports a "WITH PARSER" option. This +is available using the keyword argument ``mysql_with_parser``:: + + Index( + "my_index", + my_table.c.data, + mysql_prefix="FULLTEXT", + mysql_with_parser="ngram", + mariadb_prefix="FULLTEXT", + mariadb_with_parser="ngram", + ) + +.. versionadded:: 1.3 + + +.. _mysql_foreign_keys: + +MySQL / MariaDB Foreign Keys +----------------------------- + +MySQL and MariaDB's behavior regarding foreign keys has some important caveats. + +Foreign Key Arguments to Avoid +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Neither MySQL nor MariaDB support the foreign key arguments "DEFERRABLE", "INITIALLY", +or "MATCH". Using the ``deferrable`` or ``initially`` keyword argument with +:class:`_schema.ForeignKeyConstraint` or :class:`_schema.ForeignKey` +will have the effect of +these keywords being rendered in a DDL expression, which will then raise an +error on MySQL or MariaDB. In order to use these keywords on a foreign key while having +them ignored on a MySQL / MariaDB backend, use a custom compile rule:: + + from sqlalchemy.ext.compiler import compiles + from sqlalchemy.schema import ForeignKeyConstraint + + + @compiles(ForeignKeyConstraint, "mysql", "mariadb") + def process(element, compiler, **kw): + element.deferrable = element.initially = None + return compiler.visit_foreign_key_constraint(element, **kw) + +The "MATCH" keyword is in fact more insidious, and is explicitly disallowed +by SQLAlchemy in conjunction with the MySQL or MariaDB backends. This argument is +silently ignored by MySQL / MariaDB, but in addition has the effect of ON UPDATE and ON +DELETE options also being ignored by the backend. Therefore MATCH should +never be used with the MySQL / MariaDB backends; as is the case with DEFERRABLE and +INITIALLY, custom compilation rules can be used to correct a +ForeignKeyConstraint at DDL definition time. + +Reflection of Foreign Key Constraints +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Not all MySQL / MariaDB storage engines support foreign keys. When using the +very common ``MyISAM`` MySQL storage engine, the information loaded by table +reflection will not include foreign keys. For these tables, you may supply a +:class:`~sqlalchemy.ForeignKeyConstraint` at reflection time:: + + Table( + "mytable", + metadata, + ForeignKeyConstraint(["other_id"], ["othertable.other_id"]), + autoload_with=engine, + ) + +.. seealso:: + + :ref:`mysql_storage_engines` + +.. _mysql_unique_constraints: + +MySQL / MariaDB Unique Constraints and Reflection +---------------------------------------------------- + +SQLAlchemy supports both the :class:`.Index` construct with the +flag ``unique=True``, indicating a UNIQUE index, as well as the +:class:`.UniqueConstraint` construct, representing a UNIQUE constraint. +Both objects/syntaxes are supported by MySQL / MariaDB when emitting DDL to create +these constraints. However, MySQL / MariaDB does not have a unique constraint +construct that is separate from a unique index; that is, the "UNIQUE" +constraint on MySQL / MariaDB is equivalent to creating a "UNIQUE INDEX". + +When reflecting these constructs, the +:meth:`_reflection.Inspector.get_indexes` +and the :meth:`_reflection.Inspector.get_unique_constraints` +methods will **both** +return an entry for a UNIQUE index in MySQL / MariaDB. However, when performing +full table reflection using ``Table(..., autoload_with=engine)``, +the :class:`.UniqueConstraint` construct is +**not** part of the fully reflected :class:`_schema.Table` construct under any +circumstances; this construct is always represented by a :class:`.Index` +with the ``unique=True`` setting present in the :attr:`_schema.Table.indexes` +collection. + + +TIMESTAMP / DATETIME issues +--------------------------- + +.. _mysql_timestamp_onupdate: + +Rendering ON UPDATE CURRENT TIMESTAMP for MySQL / MariaDB's explicit_defaults_for_timestamp +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +MySQL / MariaDB have historically expanded the DDL for the :class:`_types.TIMESTAMP` +datatype into the phrase "TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE +CURRENT_TIMESTAMP", which includes non-standard SQL that automatically updates +the column with the current timestamp when an UPDATE occurs, eliminating the +usual need to use a trigger in such a case where server-side update changes are +desired. + +MySQL 5.6 introduced a new flag `explicit_defaults_for_timestamp +`_ which disables the above behavior, +and in MySQL 8 this flag defaults to true, meaning in order to get a MySQL +"on update timestamp" without changing this flag, the above DDL must be +rendered explicitly. Additionally, the same DDL is valid for use of the +``DATETIME`` datatype as well. + +SQLAlchemy's MySQL dialect does not yet have an option to generate +MySQL's "ON UPDATE CURRENT_TIMESTAMP" clause, noting that this is not a general +purpose "ON UPDATE" as there is no such syntax in standard SQL. SQLAlchemy's +:paramref:`_schema.Column.server_onupdate` parameter is currently not related +to this special MySQL behavior. + +To generate this DDL, make use of the :paramref:`_schema.Column.server_default` +parameter and pass a textual clause that also includes the ON UPDATE clause:: + + from sqlalchemy import Table, MetaData, Column, Integer, String, TIMESTAMP + from sqlalchemy import text + + metadata = MetaData() + + mytable = Table( + "mytable", + metadata, + Column("id", Integer, primary_key=True), + Column("data", String(50)), + Column( + "last_updated", + TIMESTAMP, + server_default=text( + "CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP" + ), + ), + ) + +The same instructions apply to use of the :class:`_types.DateTime` and +:class:`_types.DATETIME` datatypes:: + + from sqlalchemy import DateTime + + mytable = Table( + "mytable", + metadata, + Column("id", Integer, primary_key=True), + Column("data", String(50)), + Column( + "last_updated", + DateTime, + server_default=text( + "CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP" + ), + ), + ) + +Even though the :paramref:`_schema.Column.server_onupdate` feature does not +generate this DDL, it still may be desirable to signal to the ORM that this +updated value should be fetched. This syntax looks like the following:: + + from sqlalchemy.schema import FetchedValue + + + class MyClass(Base): + __tablename__ = "mytable" + + id = Column(Integer, primary_key=True) + data = Column(String(50)) + last_updated = Column( + TIMESTAMP, + server_default=text( + "CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP" + ), + server_onupdate=FetchedValue(), + ) + +.. _mysql_timestamp_null: + +TIMESTAMP Columns and NULL +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +MySQL historically enforces that a column which specifies the +TIMESTAMP datatype implicitly includes a default value of +CURRENT_TIMESTAMP, even though this is not stated, and additionally +sets the column as NOT NULL, the opposite behavior vs. that of all +other datatypes: + +.. sourcecode:: text + + mysql> CREATE TABLE ts_test ( + -> a INTEGER, + -> b INTEGER NOT NULL, + -> c TIMESTAMP, + -> d TIMESTAMP DEFAULT CURRENT_TIMESTAMP, + -> e TIMESTAMP NULL); + Query OK, 0 rows affected (0.03 sec) + + mysql> SHOW CREATE TABLE ts_test; + +---------+----------------------------------------------------- + | Table | Create Table + +---------+----------------------------------------------------- + | ts_test | CREATE TABLE `ts_test` ( + `a` int(11) DEFAULT NULL, + `b` int(11) NOT NULL, + `c` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, + `d` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, + `e` timestamp NULL DEFAULT NULL + ) ENGINE=MyISAM DEFAULT CHARSET=latin1 + +Above, we see that an INTEGER column defaults to NULL, unless it is specified +with NOT NULL. But when the column is of type TIMESTAMP, an implicit +default of CURRENT_TIMESTAMP is generated which also coerces the column +to be a NOT NULL, even though we did not specify it as such. + +This behavior of MySQL can be changed on the MySQL side using the +`explicit_defaults_for_timestamp +`_ configuration flag introduced in +MySQL 5.6. With this server setting enabled, TIMESTAMP columns behave like +any other datatype on the MySQL side with regards to defaults and nullability. + +However, to accommodate the vast majority of MySQL databases that do not +specify this new flag, SQLAlchemy emits the "NULL" specifier explicitly with +any TIMESTAMP column that does not specify ``nullable=False``. In order to +accommodate newer databases that specify ``explicit_defaults_for_timestamp``, +SQLAlchemy also emits NOT NULL for TIMESTAMP columns that do specify +``nullable=False``. The following example illustrates:: + + from sqlalchemy import MetaData, Integer, Table, Column, text + from sqlalchemy.dialects.mysql import TIMESTAMP + + m = MetaData() + t = Table( + "ts_test", + m, + Column("a", Integer), + Column("b", Integer, nullable=False), + Column("c", TIMESTAMP), + Column("d", TIMESTAMP, nullable=False), + ) + + + from sqlalchemy import create_engine + + e = create_engine("mysql+mysqldb://scott:tiger@localhost/test", echo=True) + m.create_all(e) + +output: + +.. sourcecode:: sql + + CREATE TABLE ts_test ( + a INTEGER, + b INTEGER NOT NULL, + c TIMESTAMP

For use within Oracle Database, two options are +available, which are the use of IDENTITY columns (Oracle Database 12 and above +only) or the association of a SEQUENCE with the column. + +Specifying GENERATED AS IDENTITY (Oracle Database 12 and above) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Starting from version 12, Oracle Database can make use of identity columns +using the :class:`_sql.Identity` to specify the autoincrementing behavior:: + + t = Table( + "mytable", + metadata, + Column("id", Integer, Identity(start=3), primary_key=True), + Column(...), + ..., + ) + +The CREATE TABLE for the above :class:`_schema.Table` object would be: + +.. sourcecode:: sql + + CREATE TABLE mytable ( + id INTEGER GENERATED BY DEFAULT AS IDENTITY (START WITH 3), + ..., + PRIMARY KEY (id) + ) + +The :class:`_schema.Identity` object support many options to control the +"autoincrementing" behavior of the column, like the starting value, the +incrementing value, etc. In addition to the standard options, Oracle Database +supports setting :paramref:`_schema.Identity.always` to ``None`` to use the +default generated mode, rendering GENERATED AS IDENTITY in the DDL. It also supports +setting :paramref:`_schema.Identity.on_null` to ``True`` to specify ON NULL +in conjunction with a 'BY DEFAULT' identity column. + +Using a SEQUENCE (all Oracle Database versions) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Older version of Oracle Database had no "autoincrement" feature: SQLAlchemy +relies upon sequences to produce these values. With the older Oracle Database +versions, *a sequence must always be explicitly specified to enable +autoincrement*. This is divergent with the majority of documentation examples +which assume the usage of an autoincrement-capable database. To specify +sequences, use the sqlalchemy.schema.Sequence object which is passed to a +Column construct:: + + t = Table( + "mytable", + metadata, + Column("id", Integer, Sequence("id_seq", start=1), primary_key=True), + Column(...), + ..., + ) + +This step is also required when using table reflection, i.e. autoload_with=engine:: + + t = Table( + "mytable", + metadata, + Column("id", Integer, Sequence("id_seq", start=1), primary_key=True), + autoload_with=engine, + ) + +.. versionchanged:: 1.4 Added :class:`_schema.Identity` construct + in a :class:`_schema.Column` to specify the option of an autoincrementing + column. + +.. _oracle_isolation_level: + +Transaction Isolation Level / Autocommit +---------------------------------------- + +Oracle Database supports "READ COMMITTED" and "SERIALIZABLE" modes of +isolation. The AUTOCOMMIT isolation level is also supported by the +python-oracledb and cx_Oracle dialects. + +To set using per-connection execution options:: + + connection = engine.connect() + connection = connection.execution_options(isolation_level="AUTOCOMMIT") + +For ``READ COMMITTED`` and ``SERIALIZABLE``, the Oracle Database dialects sets +the level at the session level using ``ALTER SESSION``, which is reverted back +to its default setting when the connection is returned to the connection pool. + +Valid values for ``isolation_level`` include: + +* ``READ COMMITTED`` +* ``AUTOCOMMIT`` +* ``SERIALIZABLE`` + +.. note:: The implementation for the + :meth:`_engine.Connection.get_isolation_level` method as implemented by the + Oracle Database dialects necessarily force the start of a transaction using the + Oracle Database DBMS_TRANSACTION.LOCAL_TRANSACTION_ID function; otherwise no + level is normally readable. + + Additionally, the :meth:`_engine.Connection.get_isolation_level` method will + raise an exception if the ``v$transaction`` view is not available due to + permissions or other reasons, which is a common occurrence in Oracle Database + installations. + + The python-oracledb and cx_Oracle dialects attempt to call the + :meth:`_engine.Connection.get_isolation_level` method when the dialect makes + its first connection to the database in order to acquire the + "default"isolation level. This default level is necessary so that the level + can be reset on a connection after it has been temporarily modified using + :meth:`_engine.Connection.execution_options` method. In the common event + that the :meth:`_engine.Connection.get_isolation_level` method raises an + exception due to ``v$transaction`` not being readable as well as any other + database-related failure, the level is assumed to be "READ COMMITTED". No + warning is emitted for this initial first-connect condition as it is + expected to be a common restriction on Oracle databases. + +.. versionadded:: 1.3.16 added support for AUTOCOMMIT to the cx_Oracle dialect + as well as the notion of a default isolation level + +.. versionadded:: 1.3.21 Added support for SERIALIZABLE as well as live + reading of the isolation level. + +.. versionchanged:: 1.3.22 In the event that the default isolation + level cannot be read due to permissions on the v$transaction view as + is common in Oracle installations, the default isolation level is hardcoded + to "READ COMMITTED" which was the behavior prior to 1.3.21. + +.. seealso:: + + :ref:`dbapi_autocommit` + +Identifier Casing +----------------- + +In Oracle Database, the data dictionary represents all case insensitive +identifier names using UPPERCASE text. This is in contradiction to the +expectations of SQLAlchemy, which assume a case insensitive name is represented +as lowercase text. + +As an example of case insensitive identifier names, consider the following table: + +.. sourcecode:: sql + + CREATE TABLE MyTable (Identifier INTEGER PRIMARY KEY) + +If you were to ask Oracle Database for information about this table, the +table name would be reported as ``MYTABLE`` and the column name would +be reported as ``IDENTIFIER``. Compare to most other databases such as +PostgreSQL and MySQL which would report these names as ``mytable`` and +``identifier``. The names are **not quoted, therefore are case insensitive**. +The special casing of ``MyTable`` and ``Identifier`` would only be maintained +if they were quoted in the table definition: + +.. sourcecode:: sql + + CREATE TABLE "MyTable" ("Identifier" INTEGER PRIMARY KEY) + +When constructing a SQLAlchemy :class:`.Table` object, **an all lowercase name +is considered to be case insensitive**. So the following table assumes +case insensitive names:: + + Table("mytable", metadata, Column("identifier", Integer, primary_key=True)) + +Whereas when mixed case or UPPERCASE names are used, case sensitivity is +assumed:: + + Table("MyTable", metadata, Column("Identifier", Integer, primary_key=True)) + +A similar situation occurs at the database driver level when emitting a +textual SQL SELECT statement and looking at column names in the DBAPI +``cursor.description`` attribute. A database like PostgreSQL will normalize +case insensitive names to be lowercase:: + + >>> pg_engine = create_engine("postgresql://scott:tiger@localhost/test") + >>> pg_connection = pg_engine.connect() + >>> result = pg_connection.exec_driver_sql("SELECT 1 AS SomeName") + >>> result.cursor.description + (Column(name='somename', type_code=23),) + +Whereas Oracle normalizes them to UPPERCASE:: + + >>> oracle_engine = create_engine("oracle+oracledb://scott:tiger@oracle18c/xe") + >>> oracle_connection = oracle_engine.connect() + >>> result = oracle_connection.exec_driver_sql( + ... "SELECT 1 AS SomeName FROM DUAL" + ... ) + >>> result.cursor.description + [('SOMENAME', , 127, None, 0, -127, True)] + +In order to achieve cross-database parity for the two cases of a. table +reflection and b. textual-only SQL statement round trips, SQLAlchemy performs a step +called **name normalization** when using the Oracle dialect. This process may +also apply to other third party dialects that have similar UPPERCASE handling +of case insensitive names. + +When using name normalization, SQLAlchemy attempts to detect if a name is +case insensitive by checking if all characters are UPPERCASE letters only; +if so, then it assumes this is a case insensitive name and is delivered as +a lowercase name. + +For table reflection, a tablename that is seen represented as all UPPERCASE +in Oracle Database's catalog tables will be assumed to have a case insensitive +name. This is what allows the ``Table`` definition to use lower case names +and be equally compatible from a reflection point of view on Oracle Database +and all other databases such as PostgreSQL and MySQL:: + + # matches a table created with CREATE TABLE mytable + Table("mytable", metadata, autoload_with=some_engine) + +Above, the all lowercase name ``"mytable"`` is case insensitive; it will match +a table reported by PostgreSQL as ``"mytable"`` and a table reported by +Oracle as ``"MYTABLE"``. If name normalization were not present, it would +not be possible for the above :class:`.Table` definition to be introspectable +in a cross-database way, since we are dealing with a case insensitive name +that is not reported by each database in the same way. + +Case sensitivity can be forced on in this case, such as if we wanted to represent +the quoted tablename ``"MYTABLE"`` with that exact casing, most simply by using +that casing directly, which will be seen as a case sensitive name:: + + # matches a table created with CREATE TABLE "MYTABLE" + Table("MYTABLE", metadata, autoload_with=some_engine) + +For the unusual case of a quoted all-lowercase name, the :class:`.quoted_name` +construct may be used:: + + from sqlalchemy import quoted_name + + # matches a table created with CREATE TABLE "mytable" + Table( + quoted_name("mytable", quote=True), metadata, autoload_with=some_engine + ) + +Name normalization also takes place when handling result sets from **purely +textual SQL strings**, that have no other :class:`.Table` or :class:`.Column` +metadata associated with them. This includes SQL strings executed using +:meth:`.Connection.exec_driver_sql` and SQL strings executed using the +:func:`.text` construct which do not include :class:`.Column` metadata. + +Returning to the Oracle Database SELECT statement, we see that even though +``cursor.description`` reports the column name as ``SOMENAME``, SQLAlchemy +name normalizes this to ``somename``:: + + >>> oracle_engine = create_engine("oracle+oracledb://scott:tiger@oracle18c/xe") + >>> oracle_connection = oracle_engine.connect() + >>> result = oracle_connection.exec_driver_sql( + ... "SELECT 1 AS SomeName FROM DUAL" + ... ) + >>> result.cursor.description + [('SOMENAME', , 127, None, 0, -127, True)] + >>> result.keys() + RMKeyView(['somename']) + +The single scenario where the above behavior produces inaccurate results +is when using an all-uppercase, quoted name. SQLAlchemy has no way to determine +that a particular name in ``cursor.description`` was quoted, and is therefore +case sensitive, or was not quoted, and should be name normalized:: + + >>> result = oracle_connection.exec_driver_sql( + ... 'SELECT 1 AS "SOMENAME" FROM DUAL' + ... ) + >>> result.cursor.description + [('SOMENAME', , 127, None, 0, -127, True)] + >>> result.keys() + RMKeyView(['somename']) + +For this case, a new feature will be available in SQLAlchemy 2.1 to disable +the name normalization behavior in specific cases. + + +.. _oracle_max_identifier_lengths: + +Maximum Identifier Lengths +-------------------------- + +SQLAlchemy is sensitive to the maximum identifier length supported by Oracle +Database. This affects generated SQL label names as well as the generation of +constraint names, particularly in the case where the constraint naming +convention feature described at :ref:`constraint_naming_conventions` is being +used. + +Oracle Database 12.2 increased the default maximum identifier length from 30 to +128. As of SQLAlchemy 1.4, the default maximum identifier length for the Oracle +dialects is 128 characters. Upon first connection, the maximum length actually +supported by the database is obtained. In all cases, setting the +:paramref:`_sa.create_engine.max_identifier_length` parameter will bypass this +change and the value given will be used as is:: + + engine = create_engine( + "oracle+oracledb://scott:tiger@localhost:1521?service_name=freepdb1", + max_identifier_length=30, + ) + +If :paramref:`_sa.create_engine.max_identifier_length` is not set, the oracledb +dialect internally uses the ``max_identifier_length`` attribute available on +driver connections since python-oracledb version 2.5. When using an older +driver version, or using the cx_Oracle dialect, SQLAlchemy will instead attempt +to use the query ``SELECT value FROM v$parameter WHERE name = 'compatible'`` +upon first connect in order to determine the effective compatibility version of +the database. The "compatibility" version is a version number that is +independent of the actual database version. It is used to assist database +migration. It is configured by an Oracle Database initialization parameter. The +compatibility version then determines the maximum allowed identifier length for +the database. If the V$ view is not available, the database version information +is used instead. + +The maximum identifier length comes into play both when generating anonymized +SQL labels in SELECT statements, but more crucially when generating constraint +names from a naming convention. It is this area that has created the need for +SQLAlchemy to change this default conservatively. For example, the following +naming convention produces two very different constraint names based on the +identifier length:: + + from sqlalchemy import Column + from sqlalchemy import Index + from sqlalchemy import Integer + from sqlalchemy import MetaData + from sqlalchemy import Table + from sqlalchemy.dialects import oracle + from sqlalchemy.schema import CreateIndex + + m = MetaData(naming_convention={"ix": "ix_%(column_0N_name)s"}) + + t = Table( + "t", + m, + Column("some_column_name_1", Integer), + Column("some_column_name_2", Integer), + Column("some_column_name_3", Integer), + ) + + ix = Index( + None, + t.c.some_column_name_1, + t.c.some_column_name_2, + t.c.some_column_name_3, + ) + + oracle_dialect = oracle.dialect(max_identifier_length=30) + print(CreateIndex(ix).compile(dialect=oracle_dialect)) + +With an identifier length of 30, the above CREATE INDEX looks like: + +.. sourcecode:: sql + + CREATE INDEX ix_some_column_name_1s_70cd ON t + (some_column_name_1, some_column_name_2, some_column_name_3) + +However with length of 128, it becomes:: + +.. sourcecode:: sql + + CREATE INDEX ix_some_column_name_1some_column_name_2some_column_name_3 ON t + (some_column_name_1, some_column_name_2, some_column_name_3) + +Applications which have run versions of SQLAlchemy prior to 1.4 on Oracle +Database version 12.2 or greater are therefore subject to the scenario of a +database migration that wishes to "DROP CONSTRAINT" on a name that was +previously generated with the shorter length. This migration will fail when +the identifier length is changed without the name of the index or constraint +first being adjusted. Such applications are strongly advised to make use of +:paramref:`_sa.create_engine.max_identifier_length` in order to maintain +control of the generation of truncated names, and to fully review and test all +database migrations in a staging environment when changing this value to ensure +that the impact of this change has been mitigated. + +.. versionchanged:: 1.4 the default max_identifier_length for Oracle Database + is 128 characters, which is adjusted down to 30 upon first connect if the + Oracle Database, or its compatibility setting, are lower than version 12.2. + + +LIMIT/OFFSET/FETCH Support +-------------------------- + +Methods like :meth:`_sql.Select.limit` and :meth:`_sql.Select.offset` make use +of ``FETCH FIRST N ROW / OFFSET N ROWS`` syntax assuming Oracle Database 12c or +above, and assuming the SELECT statement is not embedded within a compound +statement like UNION. This syntax is also available directly by using the +:meth:`_sql.Select.fetch` method. + +.. versionchanged:: 2.0 the Oracle Database dialects now use ``FETCH FIRST N + ROW / OFFSET N ROWS`` for all :meth:`_sql.Select.limit` and + :meth:`_sql.Select.offset` usage including within the ORM and legacy + :class:`_orm.Query`. To force the legacy behavior using window functions, + specify the ``enable_offset_fetch=False`` dialect parameter to + :func:`_sa.create_engine`. + +The use of ``FETCH FIRST / OFFSET`` may be disabled on any Oracle Database +version by passing ``enable_offset_fetch=False`` to :func:`_sa.create_engine`, +which will force the use of "legacy" mode that makes use of window functions. +This mode is also selected automatically when using a version of Oracle +Database prior to 12c. + +When using legacy mode, or when a :class:`.Select` statement with limit/offset +is embedded in a compound statement, an emulated approach for LIMIT / OFFSET +based on window functions is used, which involves creation of a subquery using +``ROW_NUMBER`` that is prone to performance issues as well as SQL construction +issues for complex statements. However, this approach is supported by all +Oracle Database versions. See notes below. + +Notes on LIMIT / OFFSET emulation (when fetch() method cannot be used) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If using :meth:`_sql.Select.limit` and :meth:`_sql.Select.offset`, or with the +ORM the :meth:`_orm.Query.limit` and :meth:`_orm.Query.offset` methods on an +Oracle Database version prior to 12c, the following notes apply: + +* SQLAlchemy currently makes use of ROWNUM to achieve + LIMIT/OFFSET; the exact methodology is taken from + https://blogs.oracle.com/oraclemagazine/on-rownum-and-limiting-results . + +* the "FIRST_ROWS()" optimization keyword is not used by default. To enable + the usage of this optimization directive, specify ``optimize_limits=True`` + to :func:`_sa.create_engine`. + + .. versionchanged:: 1.4 + + The Oracle Database dialect renders limit/offset integer values using a + "post compile" scheme which renders the integer directly before passing + the statement to the cursor for execution. The ``use_binds_for_limits`` + flag no longer has an effect. + + .. seealso:: + + :ref:`change_4808`. + +.. _oracle_returning: + +RETURNING Support +----------------- + +Oracle Database supports RETURNING fully for INSERT, UPDATE and DELETE +statements that are invoked with a single collection of bound parameters (that +is, a ``cursor.execute()`` style statement; SQLAlchemy does not generally +support RETURNING with :term:`executemany` statements). Multiple rows may be +returned as well. + +.. versionchanged:: 2.0 the Oracle Database backend has full support for + RETURNING on parity with other backends. + + +ON UPDATE CASCADE +----------------- + +Oracle Database doesn't have native ON UPDATE CASCADE functionality. A trigger +based solution is available at +https://web.archive.org/web/20090317041251/https://asktom.oracle.com/tkyte/update_cascade/index.html + +When using the SQLAlchemy ORM, the ORM has limited ability to manually issue +cascading updates - specify ForeignKey objects using the +"deferrable=True, initially='deferred'" keyword arguments, +and specify "passive_updates=False" on each relationship(). + +Oracle Database 8 Compatibility +------------------------------- + +.. warning:: The status of Oracle Database 8 compatibility is not known for + SQLAlchemy 2.0. + +When Oracle Database 8 is detected, the dialect internally configures itself to +the following behaviors: + +* the use_ansi flag is set to False. This has the effect of converting all + JOIN phrases into the WHERE clause, and in the case of LEFT OUTER JOIN + makes use of Oracle's (+) operator. + +* the NVARCHAR2 and NCLOB datatypes are no longer generated as DDL when + the :class:`~sqlalchemy.types.Unicode` is used - VARCHAR2 and CLOB are issued + instead. This because these types don't seem to work correctly on Oracle 8 + even though they are available. The :class:`~sqlalchemy.types.NVARCHAR` and + :class:`~sqlalchemy.dialects.oracle.NCLOB` types will always generate + NVARCHAR2 and NCLOB. + + +Synonym/DBLINK Reflection +------------------------- + +When using reflection with Table objects, the dialect can optionally search +for tables indicated by synonyms, either in local or remote schemas or +accessed over DBLINK, by passing the flag ``oracle_resolve_synonyms=True`` as +a keyword argument to the :class:`_schema.Table` construct:: + + some_table = Table( + "some_table", autoload_with=some_engine, oracle_resolve_synonyms=True + ) + +When this flag is set, the given name (such as ``some_table`` above) will be +searched not just in the ``ALL_TABLES`` view, but also within the +``ALL_SYNONYMS`` view to see if this name is actually a synonym to another +name. If the synonym is located and refers to a DBLINK, the Oracle Database +dialects know how to locate the table's information using DBLINK syntax(e.g. +``@dblink``). + +``oracle_resolve_synonyms`` is accepted wherever reflection arguments are +accepted, including methods such as :meth:`_schema.MetaData.reflect` and +:meth:`_reflection.Inspector.get_columns`. + +If synonyms are not in use, this flag should be left disabled. + +.. _oracle_constraint_reflection: + +Constraint Reflection +--------------------- + +The Oracle Database dialects can return information about foreign key, unique, +and CHECK constraints, as well as indexes on tables. + +Raw information regarding these constraints can be acquired using +:meth:`_reflection.Inspector.get_foreign_keys`, +:meth:`_reflection.Inspector.get_unique_constraints`, +:meth:`_reflection.Inspector.get_check_constraints`, and +:meth:`_reflection.Inspector.get_indexes`. + +.. versionchanged:: 1.2 The Oracle Database dialect can now reflect UNIQUE and + CHECK constraints. + +When using reflection at the :class:`_schema.Table` level, the +:class:`_schema.Table` +will also include these constraints. + +Note the following caveats: + +* When using the :meth:`_reflection.Inspector.get_check_constraints` method, + Oracle Database builds a special "IS NOT NULL" constraint for columns that + specify "NOT NULL". This constraint is **not** returned by default; to + include the "IS NOT NULL" constraints, pass the flag ``include_all=True``:: + + from sqlalchemy import create_engine, inspect + + engine = create_engine( + "oracle+oracledb://scott:tiger@localhost:1521?service_name=freepdb1" + ) + inspector = inspect(engine) + all_check_constraints = inspector.get_check_constraints( + "some_table", include_all=True + ) + +* in most cases, when reflecting a :class:`_schema.Table`, a UNIQUE constraint + will **not** be available as a :class:`.UniqueConstraint` object, as Oracle + Database mirrors unique constraints with a UNIQUE index in most cases (the + exception seems to be when two or more unique constraints represent the same + columns); the :class:`_schema.Table` will instead represent these using + :class:`.Index` with the ``unique=True`` flag set. + +* Oracle Database creates an implicit index for the primary key of a table; + this index is **excluded** from all index results. + +* the list of columns reflected for an index will not include column names + that start with SYS_NC. + +Table names with SYSTEM/SYSAUX tablespaces +------------------------------------------- + +The :meth:`_reflection.Inspector.get_table_names` and +:meth:`_reflection.Inspector.get_temp_table_names` +methods each return a list of table names for the current engine. These methods +are also part of the reflection which occurs within an operation such as +:meth:`_schema.MetaData.reflect`. By default, +these operations exclude the ``SYSTEM`` +and ``SYSAUX`` tablespaces from the operation. In order to change this, the +default list of tablespaces excluded can be changed at the engine level using +the ``exclude_tablespaces`` parameter:: + + # exclude SYSAUX and SOME_TABLESPACE, but not SYSTEM + e = create_engine( + "oracle+oracledb://scott:tiger@localhost:1521/?service_name=freepdb1", + exclude_tablespaces=["SYSAUX", "SOME_TABLESPACE"], + ) + +.. _oracle_float_support: + +FLOAT / DOUBLE Support and Behaviors +------------------------------------ + +The SQLAlchemy :class:`.Float` and :class:`.Double` datatypes are generic +datatypes that resolve to the "least surprising" datatype for a given backend. +For Oracle Database, this means they resolve to the ``FLOAT`` and ``DOUBLE`` +types:: + + >>> from sqlalchemy import cast, literal, Float + >>> from sqlalchemy.dialects import oracle + >>> float_datatype = Float() + >>> print(cast(literal(5.0), float_datatype).compile(dialect=oracle.dialect())) + CAST(:param_1 AS FLOAT) + +Oracle's ``FLOAT`` / ``DOUBLE`` datatypes are aliases for ``NUMBER``. Oracle +Database stores ``NUMBER`` values with full precision, not floating point +precision, which means that ``FLOAT`` / ``DOUBLE`` do not actually behave like +native FP values. Oracle Database instead offers special datatypes +``BINARY_FLOAT`` and ``BINARY_DOUBLE`` to deliver real 4- and 8- byte FP +values. + +SQLAlchemy supports these datatypes directly using :class:`.BINARY_FLOAT` and +:class:`.BINARY_DOUBLE`. To use the :class:`.Float` or :class:`.Double` +datatypes in a database agnostic way, while allowing Oracle backends to utilize +one of these types, use the :meth:`.TypeEngine.with_variant` method to set up a +variant:: + + >>> from sqlalchemy import cast, literal, Float + >>> from sqlalchemy.dialects import oracle + >>> float_datatype = Float().with_variant(oracle.BINARY_FLOAT(), "oracle") + >>> print(cast(literal(5.0), float_datatype).compile(dialect=oracle.dialect())) + CAST(:param_1 AS BINARY_FLOAT) + +E.g. to use this datatype in a :class:`.Table` definition:: + + my_table = Table( + "my_table", + metadata, + Column( + "fp_data", Float().with_variant(oracle.BINARY_FLOAT(), "oracle") + ), + ) + +DateTime Compatibility +---------------------- + +Oracle Database has no datatype known as ``DATETIME``, it instead has only +``DATE``, which can actually store a date and time value. For this reason, the +Oracle Database dialects provide a type :class:`_oracle.DATE` which is a +subclass of :class:`.DateTime`. This type has no special behavior, and is only +present as a "marker" for this type; additionally, when a database column is +reflected and the type is reported as ``DATE``, the time-supporting +:class:`_oracle.DATE` type is used. + +.. _oracle_table_options: + +Oracle Database Table Options +----------------------------- + +The CREATE TABLE phrase supports the following options with Oracle Database +dialects in conjunction with the :class:`_schema.Table` construct: + + +* ``ON COMMIT``:: + + Table( + "some_table", + metadata, + ..., + prefixes=["GLOBAL TEMPORARY"], + oracle_on_commit="PRESERVE ROWS", + ) + +* + ``COMPRESS``:: + + Table( + "mytable", metadata, Column("data", String(32)), oracle_compress=True + ) + + Table("mytable", metadata, Column("data", String(32)), oracle_compress=6) + + The ``oracle_compress`` parameter accepts either an integer compression + level, or ``True`` to use the default compression level. + +* + ``TABLESPACE``:: + + Table("mytable", metadata, ..., oracle_tablespace="EXAMPLE_TABLESPACE") + + The ``oracle_tablespace`` parameter specifies the tablespace in which the + table is to be created. This is useful when you want to create a table in a + tablespace other than the default tablespace of the user. + + .. versionadded:: 2.0.37 + +.. _oracle_index_options: + +Oracle Database Specific Index Options +-------------------------------------- + +Bitmap Indexes +~~~~~~~~~~~~~~ + +You can specify the ``oracle_bitmap`` parameter to create a bitmap index +instead of a B-tree index:: + + Index("my_index", my_table.c.data, oracle_bitmap=True) + +Bitmap indexes cannot be unique and cannot be compressed. SQLAlchemy will not +check for such limitations, only the database will. + +Index compression +~~~~~~~~~~~~~~~~~ + +Oracle Database has a more efficient storage mode for indexes containing lots +of repeated values. Use the ``oracle_compress`` parameter to turn on key +compression:: + + Index("my_index", my_table.c.data, oracle_compress=True) + + Index( + "my_index", + my_table.c.data1, + my_table.c.data2, + unique=True, + oracle_compress=1, + ) + +The ``oracle_compress`` parameter accepts either an integer specifying the +number of prefix columns to compress, or ``True`` to use the default (all +columns for non-unique indexes, all but the last column for unique indexes). + +.. _oracle_vector_datatype: + +VECTOR Datatype +--------------- + +Oracle Database 23ai introduced a new VECTOR datatype for artificial intelligence +and machine learning search operations. The VECTOR datatype is a homogeneous array +of 8-bit signed integers, 8-bit unsigned integers (binary), 32-bit floating-point +numbers, or 64-bit floating-point numbers. + +A vector's storage type can be either DENSE or SPARSE. A dense vector contains +meaningful values in most or all of its dimensions. In contrast, a sparse vector +has non-zero values in only a few dimensions, with the majority being zero. + +Sparse vectors are represented by the total number of vector dimensions, an array +of indices, and an array of values where each value’s location in the vector is +indicated by the corresponding indices array position. All other vector values are +treated as zero. + +The storage formats that can be used with sparse vectors are float32, float64, and +int8. Note that the binary storage format cannot be used with sparse vectors. + +Sparse vectors are supported when you are using Oracle Database 23.7 or later. + +.. seealso:: + + `Using VECTOR Data + `_ - in the documentation + for the :ref:`oracledb` driver. + +.. versionadded:: 2.0.41 - Added VECTOR datatype + +.. versionadded:: 2.0.43 - Added DENSE/SPARSE support + +CREATE TABLE support for VECTOR +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +With the :class:`.VECTOR` datatype, you can specify the number of dimensions, +the storage format, and the storage type for the data. Valid values for the +storage format are enum members of :class:`.VectorStorageFormat`. Valid values +for the storage type are enum members of :class:`.VectorStorageType`. If +storage type is not specified, a DENSE vector is created by default. + +To create a table that includes a :class:`.VECTOR` column:: + + from sqlalchemy.dialects.oracle import ( + VECTOR, + VectorStorageFormat, + VectorStorageType, + ) + + t = Table( + "t1", + metadata, + Column("id", Integer, primary_key=True), + Column( + "embedding", + VECTOR( + dim=3, + storage_format=VectorStorageFormat.FLOAT32, + storage_type=VectorStorageType.SPARSE, + ), + ), + Column(...), + ..., + ) + +Vectors can also be defined with an arbitrary number of dimensions and formats. +This allows you to specify vectors of different dimensions with the various +storage formats mentioned below. + +**Examples** + +* In this case, the storage format is flexible, allowing any vector type data to be + inserted, such as INT8 or BINARY etc:: + + vector_col: Mapped[array.array] = mapped_column(VECTOR(dim=3)) + +* The dimension is flexible in this case, meaning that any dimension vector can + be used:: + + vector_col: Mapped[array.array] = mapped_column( + VECTOR(storage_format=VectorStorageType.INT8) + ) + +* Both the dimensions and the storage format are flexible.

It was superseded by +python-oracledb which should be used instead. + +DSN vs. Hostname connections +----------------------------- + +cx_Oracle provides several methods of indicating the target database. The +dialect translates from a series of different URL forms. + +Hostname Connections with Easy Connect Syntax +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Given a hostname, port and service name of the target database, for example +from Oracle Database's Easy Connect syntax then connect in SQLAlchemy using the +``service_name`` query string parameter:: + + engine = create_engine( + "oracle+cx_oracle://scott:tiger@hostname:port?service_name=myservice&encoding=UTF-8&nencoding=UTF-8" + ) + +Note that the default driver value for encoding and nencoding was changed to +“UTF-8” in cx_Oracle 8.0 so these parameters can be omitted when using that +version, or later. + +To use a full Easy Connect string, pass it as the ``dsn`` key value in a +:paramref:`_sa.create_engine.connect_args` dictionary:: + + import cx_Oracle + + e = create_engine( + "oracle+cx_oracle://@", + connect_args={ + "user": "scott", + "password": "tiger", + "dsn": "hostname:port/myservice?transport_connect_timeout=30&expire_time=60", + }, + ) + +Connections with tnsnames.ora or to Oracle Autonomous Database +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Alternatively, if no port, database name, or service name is provided, the +dialect will use an Oracle Database DSN "connection string". This takes the +"hostname" portion of the URL as the data source name. For example, if the +``tnsnames.ora`` file contains a TNS Alias of ``myalias`` as below: + +.. sourcecode:: text + + myalias = + (DESCRIPTION = + (ADDRESS = (PROTOCOL = TCP)(HOST = mymachine.example.com)(PORT = 1521)) + (CONNECT_DATA = + (SERVER = DEDICATED) + (SERVICE_NAME = orclpdb1) + ) + ) + +The cx_Oracle dialect connects to this database service when ``myalias`` is the +hostname portion of the URL, without specifying a port, database name or +``service_name``:: + + engine = create_engine("oracle+cx_oracle://scott:tiger@myalias") + +Users of Oracle Autonomous Database should use this syntax. If the database is +configured for mutural TLS ("mTLS"), then you must also configure the cloud +wallet as shown in cx_Oracle documentation `Connecting to Autononmous Databases +`_. + +SID Connections +^^^^^^^^^^^^^^^ + +To use Oracle Database's obsolete System Identifier connection syntax, the SID +can be passed in a "database name" portion of the URL:: + + engine = create_engine( + "oracle+cx_oracle://scott:tiger@hostname:port/dbname" + ) + +Above, the DSN passed to cx_Oracle is created by ``cx_Oracle.makedsn()`` as +follows:: + + >>> import cx_Oracle + >>> cx_Oracle.makedsn("hostname", 1521, sid="dbname") + '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=1521))(CONNECT_DATA=(SID=dbname)))' + +Note that although the SQLAlchemy syntax ``hostname:port/dbname`` looks like +Oracle's Easy Connect syntax it is different. It uses a SID in place of the +service name required by Easy Connect. The Easy Connect syntax does not +support SIDs. + +Passing cx_Oracle connect arguments +----------------------------------- + +Additional connection arguments can usually be passed via the URL query string; +particular symbols like ``SYSDBA`` are intercepted and converted to the correct +symbol:: + + e = create_engine( + "oracle+cx_oracle://user:pass@dsn?encoding=UTF-8&nencoding=UTF-8&mode=SYSDBA&events=true" + ) + +.. versionchanged:: 1.3 the cx_Oracle dialect now accepts all argument names + within the URL string itself, to be passed to the cx_Oracle DBAPI. As + was the case earlier but not correctly documented, the + :paramref:`_sa.create_engine.connect_args` parameter also accepts all + cx_Oracle DBAPI connect arguments. + +To pass arguments directly to ``.connect()`` without using the query +string, use the :paramref:`_sa.create_engine.connect_args` dictionary. +Any cx_Oracle parameter value and/or constant may be passed, such as:: + + import cx_Oracle + + e = create_engine( + "oracle+cx_oracle://user:pass@dsn", + connect_args={ + "encoding": "UTF-8", + "nencoding": "UTF-8", + "mode": cx_Oracle.SYSDBA, + "events": True, + }, + ) + +Note that the default driver value for ``encoding`` and ``nencoding`` was +changed to "UTF-8" in cx_Oracle 8.0 so these parameters can be omitted when +using that version, or later. + +Options consumed by the SQLAlchemy cx_Oracle dialect outside of the driver +-------------------------------------------------------------------------- + +There are also options that are consumed by the SQLAlchemy cx_oracle dialect +itself. These options are always passed directly to :func:`_sa.create_engine` +, such as:: + + e = create_engine( + "oracle+cx_oracle://user:pass@dsn", coerce_to_decimal=False + ) + +The parameters accepted by the cx_oracle dialect are as follows: + +* ``arraysize`` - set the cx_oracle.arraysize value on cursors; defaults + to ``None``, indicating that the driver default should be used (typically + the value is 100). This setting controls how many rows are buffered when + fetching rows, and can have a significant effect on performance when + modified. + + .. versionchanged:: 2.0.26 - changed the default value from 50 to None, + to use the default value of the driver itself. + +* ``auto_convert_lobs`` - defaults to True; See :ref:`cx_oracle_lob`. + +* ``coerce_to_decimal`` - see :ref:`cx_oracle_numeric` for detail. + +* ``encoding_errors`` - see :ref:`cx_oracle_unicode_encoding_errors` for detail. + +.. _cx_oracle_sessionpool: + +Using cx_Oracle SessionPool +--------------------------- + +The cx_Oracle driver provides its own connection pool implementation that may +be used in place of SQLAlchemy's pooling functionality. The driver pool +supports Oracle Database features such dead connection detection, connection +draining for planned database downtime, support for Oracle Application +Continuity and Transparent Application Continuity, and gives support for +Database Resident Connection Pooling (DRCP). + +Using the driver pool can be achieved by using the +:paramref:`_sa.create_engine.creator` parameter to provide a function that +returns a new connection, along with setting +:paramref:`_sa.create_engine.pool_class` to ``NullPool`` to disable +SQLAlchemy's pooling:: + + import cx_Oracle + from sqlalchemy import create_engine + from sqlalchemy.pool import NullPool + + pool = cx_Oracle.SessionPool( + user="scott", + password="tiger", + dsn="orclpdb", + min=1, + max=4, + increment=1, + threaded=True, + encoding="UTF-8", + nencoding="UTF-8", + ) + + engine = create_engine( + "oracle+cx_oracle://", creator=pool.acquire, poolclass=NullPool + ) + +The above engine may then be used normally where cx_Oracle's pool handles +connection pooling:: + + with engine.connect() as conn: + print(conn.scalar("select 1 from dual")) + +As well as providing a scalable solution for multi-user applications, the +cx_Oracle session pool supports some Oracle features such as DRCP and +`Application Continuity +`_. + +Note that the pool creation parameters ``threaded``, ``encoding`` and +``nencoding`` were deprecated in later cx_Oracle releases. + +Using Oracle Database Resident Connection Pooling (DRCP) +-------------------------------------------------------- + +When using Oracle Database's DRCP, the best practice is to pass a connection +class and "purity" when acquiring a connection from the SessionPool. Refer to +the `cx_Oracle DRCP documentation +`_. + +This can be achieved by wrapping ``pool.acquire()``:: + + import cx_Oracle + from sqlalchemy import create_engine + from sqlalchemy.pool import NullPool + + pool = cx_Oracle.SessionPool( + user="scott", + password="tiger", + dsn="orclpdb", + min=2, + max=5, + increment=1, + threaded=True, + encoding="UTF-8", + nencoding="UTF-8", + ) + + + def creator(): + return pool.acquire( + cclass="MYCLASS", purity=cx_Oracle.ATTR_PURITY_SELF + ) + + + engine = create_engine( + "oracle+cx_oracle://", creator=creator, poolclass=NullPool + ) + +The above engine may then be used normally where cx_Oracle handles session +pooling and Oracle Database additionally uses DRCP:: + + with engine.connect() as conn: + print(conn.scalar("select 1 from dual")) + +.. _cx_oracle_unicode: + +Unicode +------- + +As is the case for all DBAPIs under Python 3, all strings are inherently +Unicode strings. In all cases however, the driver requires an explicit +encoding configuration. + +Ensuring the Correct Client Encoding +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The long accepted standard for establishing client encoding for nearly all +Oracle Database related software is via the `NLS_LANG +`_ environment +variable. Older versions of cx_Oracle use this environment variable as the +source of its encoding configuration. The format of this variable is +Territory_Country.CharacterSet; a typical value would be +``AMERICAN_AMERICA.AL32UTF8``. cx_Oracle version 8 and later use the character +set "UTF-8" by default, and ignore the character set component of NLS_LANG. + +The cx_Oracle driver also supported a programmatic alternative which is to pass +the ``encoding`` and ``nencoding`` parameters directly to its ``.connect()`` +function. These can be present in the URL as follows:: + + engine = create_engine( + "oracle+cx_oracle://scott:tiger@tnsalias?encoding=UTF-8&nencoding=UTF-8" + ) + +For the meaning of the ``encoding`` and ``nencoding`` parameters, please +consult +`Characters Sets and National Language Support (NLS) `_. + +.. seealso:: + + `Characters Sets and National Language Support (NLS) `_ + - in the cx_Oracle documentation. + + +Unicode-specific Column datatypes +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The Core expression language handles unicode data by use of the +:class:`.Unicode` and :class:`.UnicodeText` datatypes. These types correspond +to the VARCHAR2 and CLOB Oracle Database datatypes by default. When using +these datatypes with Unicode data, it is expected that the database is +configured with a Unicode-aware character set, as well as that the ``NLS_LANG`` +environment variable is set appropriately (this applies to older versions of +cx_Oracle), so that the VARCHAR2 and CLOB datatypes can accommodate the data. + +In the case that Oracle Database is not configured with a Unicode character +set, the two options are to use the :class:`_types.NCHAR` and +:class:`_oracle.NCLOB` datatypes explicitly, or to pass the flag +``use_nchar_for_unicode=True`` to :func:`_sa.create_engine`, which will cause +the SQLAlchemy dialect to use NCHAR/NCLOB for the :class:`.Unicode` / +:class:`.UnicodeText` datatypes instead of VARCHAR/CLOB. + +.. versionchanged:: 1.3 The :class:`.Unicode` and :class:`.UnicodeText` + datatypes now correspond to the ``VARCHAR2`` and ``CLOB`` Oracle Database + datatypes unless the ``use_nchar_for_unicode=True`` is passed to the dialect + when :func:`_sa.create_engine` is called. + + +.. _cx_oracle_unicode_encoding_errors: + +Encoding Errors +^^^^^^^^^^^^^^^ + +For the unusual case that data in Oracle Database is present with a broken +encoding, the dialect accepts a parameter ``encoding_errors`` which will be +passed to Unicode decoding functions in order to affect how decoding errors are +handled. The value is ultimately consumed by the Python `decode +`_ function, and +is passed both via cx_Oracle's ``encodingErrors`` parameter consumed by +``Cursor.var()``, as well as SQLAlchemy's own decoding function, as the +cx_Oracle dialect makes use of both under different circumstances. + +.. versionadded:: 1.3.11 + + +.. _cx_oracle_setinputsizes: + +Fine grained control over cx_Oracle data binding performance with setinputsizes +------------------------------------------------------------------------------- + +The cx_Oracle DBAPI has a deep and fundamental reliance upon the usage of the +DBAPI ``setinputsizes()`` call. The purpose of this call is to establish the +datatypes that are bound to a SQL statement for Python values being passed as +parameters. While virtually no other DBAPI assigns any use to the +``setinputsizes()`` call, the cx_Oracle DBAPI relies upon it heavily in its +interactions with the Oracle Database client interface, and in some scenarios +it is not possible for SQLAlchemy to know exactly how data should be bound, as +some settings can cause profoundly different performance characteristics, while +altering the type coercion behavior at the same time. + +Users of the cx_Oracle dialect are **strongly encouraged** to read through +cx_Oracle's list of built-in datatype symbols at +https://cx-oracle.readthedocs.io/en/latest/api_manual/module.html#database-types. +Note that in some cases, significant performance degradation can occur when +using these types vs. not, in particular when specifying ``cx_Oracle.CLOB``. + +On the SQLAlchemy side, the :meth:`.DialectEvents.do_setinputsizes` event can +be used both for runtime visibility (e.g. logging) of the setinputsizes step as +well as to fully control how ``setinputsizes()`` is used on a per-statement +basis. + +.. versionadded:: 1.2.9 Added :meth:`.DialectEvents.setinputsizes` + + +Example 1 - logging all setinputsizes calls +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The following example illustrates how to log the intermediary values from a +SQLAlchemy perspective before they are converted to the raw ``setinputsizes()`` +parameter dictionary. The keys of the dictionary are :class:`.BindParameter` +objects which have a ``.key`` and a ``.type`` attribute:: + + from sqlalchemy import create_engine, event + + engine = create_engine("oracle+cx_oracle://scott:tiger@host/xe") + + + @event.listens_for(engine, "do_setinputsizes") + def _log_setinputsizes(inputsizes, cursor, statement, parameters, context): + for bindparam, dbapitype in inputsizes.items(): + log.info( + "Bound parameter name: %s SQLAlchemy type: %r DBAPI object: %s", + bindparam.key, + bindparam.type, + dbapitype, + ) + +Example 2 - remove all bindings to CLOB +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The ``CLOB`` datatype in cx_Oracle incurs a significant performance overhead, +however is set by default for the ``Text`` type within the SQLAlchemy 1.2 +series. This setting can be modified as follows:: + + from sqlalchemy import create_engine, event + from cx_Oracle import CLOB + + engine = create_engine("oracle+cx_oracle://scott:tiger@host/xe") + + + @event.listens_for(engine, "do_setinputsizes") + def _remove_clob(inputsizes, cursor, statement, parameters, context): + for bindparam, dbapitype in list(inputsizes.items()): + if dbapitype is CLOB: + del inputsizes[bindparam] + +.. _cx_oracle_lob: + +LOB Datatypes +-------------- + +LOB datatypes refer to the "large object" datatypes such as CLOB, NCLOB and +BLOB. Modern versions of cx_Oracle is optimized for these datatypes to be +delivered as a single buffer. As such, SQLAlchemy makes use of these newer type +handlers by default. + +To disable the use of newer type handlers and deliver LOB objects as classic +buffered objects with a ``read()`` method, the parameter +``auto_convert_lobs=False`` may be passed to :func:`_sa.create_engine`, +which takes place only engine-wide. + +.. _cx_oracle_returning: + +RETURNING Support +----------------- + +The cx_Oracle dialect implements RETURNING using OUT parameters. +The dialect supports RETURNING fully. + +Two Phase Transactions Not Supported +------------------------------------ + +Two phase transactions are **not supported** under cx_Oracle due to poor driver +support. The newer :ref:`oracledb` dialect however **does** support two phase +transactions. + +.. _cx_oracle_numeric: + +Precision Numerics +------------------ + +SQLAlchemy's numeric types can handle receiving and returning values as Python +``Decimal`` objects or float objects. When a :class:`.Numeric` object, or a +subclass such as :class:`.Float`, :class:`_oracle.DOUBLE_PRECISION` etc. is in +use, the :paramref:`.Numeric.asdecimal` flag determines if values should be +coerced to ``Decimal`` upon return, or returned as float objects. To make +matters more complicated under Oracle Database, the ``NUMBER`` type can also +represent integer values if the "scale" is zero, so the Oracle +Database-specific :class:`_oracle.NUMBER` type takes this into account as well. + +The cx_Oracle dialect makes extensive use of connection- and cursor-level +"outputtypehandler" callables in order to coerce numeric values as requested. +These callables are specific to the specific flavor of :class:`.Numeric` in +use, as well as if no SQLAlchemy typing objects are present. There are +observed scenarios where Oracle Database may send incomplete or ambiguous +information about the numeric types being returned, such as a query where the +numeric types are buried under multiple levels of subquery. The type handlers +do their best to make the right decision in all cases, deferring to the +underlying cx_Oracle DBAPI for all those cases where the driver can make the +best decision. + +When no typing objects are present, as when executing plain SQL strings, a +default "outputtypehandler" is present which will generally return numeric +values which specify precision and scale as Python ``Decimal`` objects. To +disable this coercion to decimal for performance reasons, pass the flag +``coerce_to_decimal=False`` to :func:`_sa.create_engine`:: + + engine = create_engine("oracle+cx_oracle://dsn", coerce_to_decimal=False) + +The ``coerce_to_decimal`` flag only impacts the results of plain string +SQL statements that are not otherwise associated with a :class:`.Numeric` +SQLAlchemy type (or a subclass of such). + +.. versionchanged:: 1.2 The numeric handling system for cx_Oracle has been + reworked to take advantage of newer cx_Oracle features as well + as better integration of outputtypehandlers. + +""" # noqa +from __future__ import annotations + +import decimal +import random +import re + +from . import base as oracle +from .base import OracleCompiler +from .base import OracleDialect +from .base import OracleExecutionContext +from .types import _OracleDateLiteralRender +from ... import exc +from ... import util +from ...engine import cursor as _cursor +from ...engine import interfaces +from ...engine import processors +from ...sql import sqltypes +from ...sql._typing import is_sql_compiler + +# source: +# https://github.com/oracle/python-cx_Oracle/issues/596#issuecomment-999243649 +_CX_ORACLE_MAGIC_LOB_SIZE = 131072 + + +class _OracleInteger(sqltypes.Integer): + def get_dbapi_type(self, dbapi): + # see https://github.com/oracle/python-cx_Oracle/issues/ + # 208#issuecomment-409715955 + return int + + def _cx_oracle_var(self, dialect, cursor, arraysize=None): + cx_Oracle = dialect.dbapi + return cursor.var( + cx_Oracle.STRING, + 255, + arraysize=arraysize if arraysize is not None else cursor.arraysize, + outconverter=int, + ) + + def _cx_oracle_outputtypehandler(self, dialect): + def handler(cursor, name, default_type, size, precision, scale): + return self._cx_oracle_var(dialect, cursor) + + return handler + + +class _OracleNumeric(sqltypes.Numeric): + is_number = False + + def bind_processor(self, dialect): + if self.scale == 0: + return None + elif self.asdecimal: + processor = processors.to_decimal_processor_factory( + decimal.Decimal, self._effective_decimal_return_scale + ) + + def process(value): + if isinstance(value, (int, float)): + return processor(value) + elif value is not None and value.is_infinite(): + return float(value) + else: + return value + + return process + else: + return processors.to_float + + def result_processor(self, dialect, coltype): + return None + + def _cx_oracle_outputtypehandler(self, dialect): + cx_Oracle = dialect.dbapi + + def handler(cursor, name, default_type, size, precision, scale): + outconverter = None + + if precision: + if self.asdecimal: + if default_type == cx_Oracle.NATIVE_FLOAT: + # receiving float and doing Decimal after the fact + # allows for float("inf") to be handled + type_ = default_type + outconverter = decimal.Decimal + else: + type_ = decimal.Decimal + else: + if self.is_number and scale == 0: + # integer. cx_Oracle is observed to handle the widest + # variety of ints when no directives are passed, + # from 5.2 to 7.0.

It features a default +"thin" client mode that requires no dependencies, and an optional "thick" mode +that uses Oracle Client libraries. It supports SQLAlchemy features including +two phase transactions and Asyncio. + +Python-oracle is the renamed, updated cx_Oracle driver. Oracle is no longer +doing any releases in the cx_Oracle namespace. + +The SQLAlchemy ``oracledb`` dialect provides both a sync and an async +implementation under the same dialect name. The proper version is +selected depending on how the engine is created: + +* calling :func:`_sa.create_engine` with ``oracle+oracledb://...`` will + automatically select the sync version:: + + from sqlalchemy import create_engine + + sync_engine = create_engine( + "oracle+oracledb://scott:tiger@localhost?service_name=FREEPDB1" + ) + +* calling :func:`_asyncio.create_async_engine` with ``oracle+oracledb://...`` + will automatically select the async version:: + + from sqlalchemy.ext.asyncio import create_async_engine + + asyncio_engine = create_async_engine( + "oracle+oracledb://scott:tiger@localhost?service_name=FREEPDB1" + ) + + The asyncio version of the dialect may also be specified explicitly using the + ``oracledb_async`` suffix:: + + from sqlalchemy.ext.asyncio import create_async_engine + + asyncio_engine = create_async_engine( + "oracle+oracledb_async://scott:tiger@localhost?service_name=FREEPDB1" + ) + +.. versionadded:: 2.0.25 added support for the async version of oracledb. + +Thick mode support +------------------ + +By default, the python-oracledb driver runs in a "thin" mode that does not +require Oracle Client libraries to be installed. The driver also supports a +"thick" mode that uses Oracle Client libraries to get functionality such as +Oracle Application Continuity. + +To enable thick mode, call `oracledb.init_oracle_client() +`_ +explicitly, or pass the parameter ``thick_mode=True`` to +:func:`_sa.create_engine`. To pass custom arguments to +``init_oracle_client()``, like the ``lib_dir`` path, a dict may be passed, for +example:: + + engine = sa.create_engine( + "oracle+oracledb://...", + thick_mode={ + "lib_dir": "/path/to/oracle/client/lib", + "config_dir": "/path/to/network_config_file_directory", + "driver_name": "my-app : 1.0.0", + }, + ) + +Note that passing a ``lib_dir`` path should only be done on macOS or +Windows. On Linux it does not behave as you might expect. + +.. seealso:: + + python-oracledb documentation `Enabling python-oracledb Thick mode + `_ + +Connecting to Oracle Database +----------------------------- + +python-oracledb provides several methods of indicating the target database. +The dialect translates from a series of different URL forms. + +Given the hostname, port and service name of the target database, you can +connect in SQLAlchemy using the ``service_name`` query string parameter:: + + engine = create_engine( + "oracle+oracledb://scott:tiger@hostname:port?service_name=myservice" + ) + +Connecting with Easy Connect strings +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +You can pass any valid python-oracledb connection string as the ``dsn`` key +value in a :paramref:`_sa.create_engine.connect_args` dictionary. See +python-oracledb documentation `Oracle Net Services Connection Strings +`_. + +For example to use an `Easy Connect string +`_ +with a timeout to prevent connection establishment from hanging if the network +transport to the database cannot be established in 30 seconds, and also setting +a keep-alive time of 60 seconds to stop idle network connections from being +terminated by a firewall:: + + e = create_engine( + "oracle+oracledb://@", + connect_args={ + "user": "scott", + "password": "tiger", + "dsn": "hostname:port/myservice?transport_connect_timeout=30&expire_time=60", + }, + ) + +The Easy Connect syntax has been enhanced during the life of Oracle Database. +Review the documentation for your database version. The current documentation +is at `Understanding the Easy Connect Naming Method +`_. + +The general syntax is similar to: + +.. sourcecode:: text + + [[protocol:]//]host[:port][/[service_name]][?parameter_name=value{¶meter_name=value}] + +Note that although the SQLAlchemy URL syntax ``hostname:port/dbname`` looks +like Oracle's Easy Connect syntax, it is different. SQLAlchemy's URL requires a +system identifier (SID) for the ``dbname`` component:: + + engine = create_engine("oracle+oracledb://scott:tiger@hostname:port/sid") + +Easy Connect syntax does not support SIDs. It uses services names, which are +the preferred choice for connecting to Oracle Database. + +Passing python-oracledb connect arguments +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Other python-oracledb driver `connection options +`_ +can be passed in ``connect_args``. For example:: + + e = create_engine( + "oracle+oracledb://@", + connect_args={ + "user": "scott", + "password": "tiger", + "dsn": "hostname:port/myservice", + "events": True, + "mode": oracledb.AUTH_MODE_SYSDBA, + }, + ) + +Connecting with tnsnames.ora TNS aliases +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +If no port, database name, or service name is provided, the dialect will use an +Oracle Database DSN "connection string". This takes the "hostname" portion of +the URL as the data source name. For example, if the ``tnsnames.ora`` file +contains a `TNS Alias +`_ +of ``myalias`` as below: + +.. sourcecode:: text + + myalias = + (DESCRIPTION = + (ADDRESS = (PROTOCOL = TCP)(HOST = mymachine.example.com)(PORT = 1521)) + (CONNECT_DATA = + (SERVER = DEDICATED) + (SERVICE_NAME = orclpdb1) + ) + ) + +The python-oracledb dialect connects to this database service when ``myalias`` is the +hostname portion of the URL, without specifying a port, database name or +``service_name``:: + + engine = create_engine("oracle+oracledb://scott:tiger@myalias") + +Connecting to Oracle Autonomous Database +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Users of Oracle Autonomous Database should use either use the TNS Alias URL +shown above, or pass the TNS Alias as the ``dsn`` key value in a +:paramref:`_sa.create_engine.connect_args` dictionary. + +If Oracle Autonomous Database is configured for mutual TLS ("mTLS") +connections, then additional configuration is required as shown in `Connecting +to Oracle Cloud Autonomous Databases +`_. In +summary, Thick mode users should configure file locations and set the wallet +path in ``sqlnet.ora`` appropriately:: + + e = create_engine( + "oracle+oracledb://@", + thick_mode={ + # directory containing tnsnames.ora and cwallet.so + "config_dir": "/opt/oracle/wallet_dir", + }, + connect_args={ + "user": "scott", + "password": "tiger", + "dsn": "mydb_high", + }, + ) + +Thin mode users of mTLS should pass the appropriate directories and PEM wallet +password when creating the engine, similar to:: + + e = create_engine( + "oracle+oracledb://@", + connect_args={ + "user": "scott", + "password": "tiger", + "dsn": "mydb_high", + "config_dir": "/opt/oracle/wallet_dir", # directory containing tnsnames.ora + "wallet_location": "/opt/oracle/wallet_dir", # directory containing ewallet.pem + "wallet_password": "top secret", # password for the PEM file + }, + ) + +Typically ``config_dir`` and ``wallet_location`` are the same directory, which +is where the Oracle Autonomous Database wallet zip file was extracted. Note +this directory should be protected. + +Using python-oracledb Connection Pooling +---------------------------------------- + +The python-oracledb driver provides its own connection pool implementation that +may be used in place of SQLAlchemy's pooling functionality. The driver pool +gives support for high availability features such as dead connection detection, +connection draining for planned database downtime, support for Oracle +Application Continuity and Transparent Application Continuity, and gives +support for `Database Resident Connection Pooling (DRCP) +`_. + +To take advantage of python-oracledb's pool, use the +:paramref:`_sa.create_engine.creator` parameter to provide a function that +returns a new connection, along with setting +:paramref:`_sa.create_engine.pool_class` to ``NullPool`` to disable +SQLAlchemy's pooling:: + + import oracledb + from sqlalchemy import create_engine + from sqlalchemy import text + from sqlalchemy.pool import NullPool + + # Uncomment to use the optional python-oracledb Thick mode. + # Review the python-oracledb doc for the appropriate parameters + # oracledb.init_oracle_client() + + pool = oracledb.create_pool( + user="scott", + password="tiger", + dsn="localhost:1521/freepdb1", + min=1, + max=4, + increment=1, + ) + engine = create_engine( + "oracle+oracledb://", creator=pool.acquire, poolclass=NullPool + ) + +The above engine may then be used normally. Internally, python-oracledb handles +connection pooling:: + + with engine.connect() as conn: + print(conn.scalar(text("select 1 from dual"))) + +Refer to the python-oracledb documentation for `oracledb.create_pool() +`_ +for the arguments that can be used when creating a connection pool. + +.. _drcp: + +Using Oracle Database Resident Connection Pooling (DRCP) +-------------------------------------------------------- + +When using Oracle Database's Database Resident Connection Pooling (DRCP), the +best practice is to specify a connection class and "purity". Refer to the +`python-oracledb documentation on DRCP +`_. +For example:: + + import oracledb + from sqlalchemy import create_engine + from sqlalchemy import text + from sqlalchemy.pool import NullPool + + # Uncomment to use the optional python-oracledb Thick mode. + # Review the python-oracledb doc for the appropriate parameters + # oracledb.init_oracle_client() + + pool = oracledb.create_pool( + user="scott", + password="tiger", + dsn="localhost:1521/freepdb1", + min=1, + max=4, + increment=1, + cclass="MYCLASS", + purity=oracledb.PURITY_SELF, + ) + engine = create_engine( + "oracle+oracledb://", creator=pool.acquire, poolclass=NullPool + ) + +The above engine may then be used normally where python-oracledb handles +application connection pooling and Oracle Database additionally uses DRCP:: + + with engine.connect() as conn: + print(conn.scalar(text("select 1 from dual"))) + +If you wish to use different connection classes or purities for different +connections, then wrap ``pool.acquire()``:: + + import oracledb + from sqlalchemy import create_engine + from sqlalchemy import text + from sqlalchemy.pool import NullPool + + # Uncomment to use python-oracledb Thick mode. + # Review the python-oracledb doc for the appropriate parameters + # oracledb.init_oracle_client() + + pool = oracledb.create_pool( + user="scott", + password="tiger", + dsn="localhost:1521/freepdb1", + min=1, + max=4, + increment=1, + cclass="MYCLASS", + purity=oracledb.PURITY_SELF, + ) + + + def creator(): + return pool.acquire(cclass="MYOTHERCLASS", purity=oracledb.PURITY_NEW) + + + engine = create_engine( + "oracle+oracledb://", creator=creator, poolclass=NullPool + ) + +Engine Options consumed by the SQLAlchemy oracledb dialect outside of the driver +-------------------------------------------------------------------------------- + +There are also options that are consumed by the SQLAlchemy oracledb dialect +itself. These options are always passed directly to :func:`_sa.create_engine`, +such as:: + + e = create_engine("oracle+oracledb://user:pass@tnsalias", arraysize=500) + +The parameters accepted by the oracledb dialect are as follows: + +* ``arraysize`` - set the driver cursor.arraysize value. It defaults to + ``None``, indicating that the driver default value of 100 should be used. + This setting controls how many rows are buffered when fetching rows, and can + have a significant effect on performance if increased for queries that return + large numbers of rows. + + .. versionchanged:: 2.0.26 - changed the default value from 50 to None, + to use the default value of the driver itself. + +* ``auto_convert_lobs`` - defaults to True; See :ref:`oracledb_lob`. + +* ``coerce_to_decimal`` - see :ref:`oracledb_numeric` for detail. + +* ``encoding_errors`` - see :ref:`oracledb_unicode_encoding_errors` for detail. + +.. _oracledb_unicode: + +Unicode +------- + +As is the case for all DBAPIs under Python 3, all strings are inherently +Unicode strings. + +Ensuring the Correct Client Encoding +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +In python-oracledb, the encoding used for all character data is "UTF-8". + +Unicode-specific Column datatypes +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The Core expression language handles unicode data by use of the +:class:`.Unicode` and :class:`.UnicodeText` datatypes. These types correspond +to the VARCHAR2 and CLOB Oracle Database datatypes by default. When using +these datatypes with Unicode data, it is expected that the database is +configured with a Unicode-aware character set so that the VARCHAR2 and CLOB +datatypes can accommodate the data. + +In the case that Oracle Database is not configured with a Unicode character +set, the two options are to use the :class:`_types.NCHAR` and +:class:`_oracle.NCLOB` datatypes explicitly, or to pass the flag +``use_nchar_for_unicode=True`` to :func:`_sa.create_engine`, which will cause +the SQLAlchemy dialect to use NCHAR/NCLOB for the :class:`.Unicode` / +:class:`.UnicodeText` datatypes instead of VARCHAR/CLOB. + +.. versionchanged:: 1.3 The :class:`.Unicode` and :class:`.UnicodeText` + datatypes now correspond to the ``VARCHAR2`` and ``CLOB`` Oracle Database + datatypes unless the ``use_nchar_for_unicode=True`` is passed to the dialect + when :func:`_sa.create_engine` is called. + + +.. _oracledb_unicode_encoding_errors: + +Encoding Errors +^^^^^^^^^^^^^^^ + +For the unusual case that data in Oracle Database is present with a broken +encoding, the dialect accepts a parameter ``encoding_errors`` which will be +passed to Unicode decoding functions in order to affect how decoding errors are +handled. The value is ultimately consumed by the Python `decode +`_ function, and +is passed both via python-oracledb's ``encodingErrors`` parameter consumed by +``Cursor.var()``, as well as SQLAlchemy's own decoding function, as the +python-oracledb dialect makes use of both under different circumstances. + +.. versionadded:: 1.3.11 + + +.. _oracledb_setinputsizes: + +Fine grained control over python-oracledb data binding with setinputsizes +------------------------------------------------------------------------- + +The python-oracle DBAPI has a deep and fundamental reliance upon the usage of +the DBAPI ``setinputsizes()`` call. The purpose of this call is to establish +the datatypes that are bound to a SQL statement for Python values being passed +as parameters. While virtually no other DBAPI assigns any use to the +``setinputsizes()`` call, the python-oracledb DBAPI relies upon it heavily in +its interactions with the Oracle Database, and in some scenarios it is not +possible for SQLAlchemy to know exactly how data should be bound, as some +settings can cause profoundly different performance characteristics, while +altering the type coercion behavior at the same time. + +Users of the oracledb dialect are **strongly encouraged** to read through +python-oracledb's list of built-in datatype symbols at `Database Types +`_ +Note that in some cases, significant performance degradation can occur when +using these types vs. not. + +On the SQLAlchemy side, the :meth:`.DialectEvents.do_setinputsizes` event can +be used both for runtime visibility (e.g. logging) of the setinputsizes step as +well as to fully control how ``setinputsizes()`` is used on a per-statement +basis. + +.. versionadded:: 1.2.9 Added :meth:`.DialectEvents.setinputsizes` + + +Example 1 - logging all setinputsizes calls +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The following example illustrates how to log the intermediary values from a +SQLAlchemy perspective before they are converted to the raw ``setinputsizes()`` +parameter dictionary. The keys of the dictionary are :class:`.BindParameter` +objects which have a ``.key`` and a ``.type`` attribute:: + + from sqlalchemy import create_engine, event + + engine = create_engine( + "oracle+oracledb://scott:tiger@localhost:1521?service_name=freepdb1" + ) + + + @event.listens_for(engine, "do_setinputsizes") + def _log_setinputsizes(inputsizes, cursor, statement, parameters, context): + for bindparam, dbapitype in inputsizes.items(): + log.info( + "Bound parameter name: %s SQLAlchemy type: %r DBAPI object: %s", + bindparam.key, + bindparam.type, + dbapitype, + ) + +Example 2 - remove all bindings to CLOB +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +For performance, fetching LOB datatypes from Oracle Database is set by default +for the ``Text`` type within SQLAlchemy. This setting can be modified as +follows:: + + + from sqlalchemy import create_engine, event + from oracledb import CLOB + + engine = create_engine( + "oracle+oracledb://scott:tiger@localhost:1521?service_name=freepdb1" + ) + + + @event.listens_for(engine, "do_setinputsizes") + def _remove_clob(inputsizes, cursor, statement, parameters, context): + for bindparam, dbapitype in list(inputsizes.items()): + if dbapitype is CLOB: + del inputsizes[bindparam] + +.. _oracledb_lob: + +LOB Datatypes +-------------- + +LOB datatypes refer to the "large object" datatypes such as CLOB, NCLOB and +BLOB. Oracle Database can efficiently return these datatypes as a single +buffer. SQLAlchemy makes use of type handlers to do this by default. + +To disable the use of the type handlers and deliver LOB objects as classic +buffered objects with a ``read()`` method, the parameter +``auto_convert_lobs=False`` may be passed to :func:`_sa.create_engine`. + +.. _oracledb_returning: + +RETURNING Support +----------------- + +The oracledb dialect implements RETURNING using OUT parameters. The dialect +supports RETURNING fully. + +Two Phase Transaction Support +----------------------------- + +Two phase transactions are fully supported with python-oracledb. (Thin mode +requires python-oracledb 2.3). APIs for two phase transactions are provided at +the Core level via :meth:`_engine.Connection.begin_twophase` and +:paramref:`_orm.Session.twophase` for transparent ORM use. + +.. versionchanged:: 2.0.32 added support for two phase transactions + +.. _oracledb_numeric: + +Precision Numerics +------------------ + +SQLAlchemy's numeric types can handle receiving and returning values as Python +``Decimal`` objects or float objects. When a :class:`.Numeric` object, or a +subclass such as :class:`.Float`, :class:`_oracle.DOUBLE_PRECISION` etc. is in +use, the :paramref:`.Numeric.asdecimal` flag determines if values should be +coerced to ``Decimal`` upon return, or returned as float objects. To make +matters more complicated under Oracle Database, the ``NUMBER`` type can also +represent integer values if the "scale" is zero, so the Oracle +Database-specific :class:`_oracle.NUMBER` type takes this into account as well. + +The oracledb dialect makes extensive use of connection- and cursor-level +"outputtypehandler" callables in order to coerce numeric values as requested. +These callables are specific to the specific flavor of :class:`.Numeric` in +use, as well as if no SQLAlchemy typing objects are present. There are +observed scenarios where Oracle Database may send incomplete or ambiguous +information about the numeric types being returned, such as a query where the +numeric types are buried under multiple levels of subquery.

The +syntax is the same, +using ``host=:`` combinations as additional query string arguments; +however, there is no default port, so all hosts must have a complete port number +present, otherwise an exception is raised:: + + engine = create_async_engine( + "postgresql+asyncpg://user:password@/dbname?host=HostA:5432&host=HostB:5432&host=HostC:5432" + ) + +For complete background on this syntax, see :ref:`psycopg2_multi_host`. + +.. versionadded:: 2.0.18 + +.. seealso:: + + :ref:`psycopg2_multi_host` + +.. _asyncpg_prepared_statement_cache: + +Prepared Statement Cache +-------------------------- + +The asyncpg SQLAlchemy dialect makes use of ``asyncpg.connection.prepare()`` +for all statements. The prepared statement objects are cached after +construction which appears to grant a 10% or more performance improvement for +statement invocation. The cache is on a per-DBAPI connection basis, which +means that the primary storage for prepared statements is within DBAPI +connections pooled within the connection pool. The size of this cache +defaults to 100 statements per DBAPI connection and may be adjusted using the +``prepared_statement_cache_size`` DBAPI argument (note that while this argument +is implemented by SQLAlchemy, it is part of the DBAPI emulation portion of the +asyncpg dialect, therefore is handled as a DBAPI argument, not a dialect +argument):: + + + engine = create_async_engine( + "postgresql+asyncpg://user:pass@hostname/dbname?prepared_statement_cache_size=500" + ) + +To disable the prepared statement cache, use a value of zero:: + + engine = create_async_engine( + "postgresql+asyncpg://user:pass@hostname/dbname?prepared_statement_cache_size=0" + ) + +.. versionadded:: 1.4.0b2 Added ``prepared_statement_cache_size`` for asyncpg. + + +.. warning:: The ``asyncpg`` database driver necessarily uses caches for + PostgreSQL type OIDs, which become stale when custom PostgreSQL datatypes + such as ``ENUM`` objects are changed via DDL operations. Additionally, + prepared statements themselves which are optionally cached by SQLAlchemy's + driver as described above may also become "stale" when DDL has been emitted + to the PostgreSQL database which modifies the tables or other objects + involved in a particular prepared statement. + + The SQLAlchemy asyncpg dialect will invalidate these caches within its local + process when statements that represent DDL are emitted on a local + connection, but this is only controllable within a single Python process / + database engine. If DDL changes are made from other database engines + and/or processes, a running application may encounter asyncpg exceptions + ``InvalidCachedStatementError`` and/or ``InternalServerError("cache lookup + failed for type ")`` if it refers to pooled database connections which + operated upon the previous structures. The SQLAlchemy asyncpg dialect will + recover from these error cases when the driver raises these exceptions by + clearing its internal caches as well as those of the asyncpg driver in + response to them, but cannot prevent them from being raised in the first + place if the cached prepared statement or asyncpg type caches have gone + stale, nor can it retry the statement as the PostgreSQL transaction is + invalidated when these errors occur. + +.. _asyncpg_prepared_statement_name: + +Prepared Statement Name with PGBouncer +-------------------------------------- + +By default, asyncpg enumerates prepared statements in numeric order, which +can lead to errors if a name has already been taken for another prepared +statement. This issue can arise if your application uses database proxies +such as PgBouncer to handle connections. One possible workaround is to +use dynamic prepared statement names, which asyncpg now supports through +an optional ``name`` value for the statement name. This allows you to +generate your own unique names that won't conflict with existing ones. +To achieve this, you can provide a function that will be called every time +a prepared statement is prepared:: + + from uuid import uuid4 + + engine = create_async_engine( + "postgresql+asyncpg://user:pass@somepgbouncer/dbname", + poolclass=NullPool, + connect_args={ + "prepared_statement_name_func": lambda: f"__asyncpg_{uuid4()}__", + }, + ) + +.. seealso:: + + https://github.com/MagicStack/asyncpg/issues/837 + + https://github.com/sqlalchemy/sqlalchemy/issues/6467 + +.. warning:: When using PGBouncer, to prevent a buildup of useless prepared statements in + your application, it's important to use the :class:`.NullPool` pool + class, and to configure PgBouncer to use `DISCARD `_ + when returning connections. The DISCARD command is used to release resources held by the db connection, + including prepared statements. Without proper setup, prepared statements can + accumulate quickly and cause performance issues. + +Disabling the PostgreSQL JIT to improve ENUM datatype handling +--------------------------------------------------------------- + +Asyncpg has an `issue `_ when +using PostgreSQL ENUM datatypes, where upon the creation of new database +connections, an expensive query may be emitted in order to retrieve metadata +regarding custom types which has been shown to negatively affect performance. +To mitigate this issue, the PostgreSQL "jit" setting may be disabled from the +client using this setting passed to :func:`_asyncio.create_async_engine`:: + + engine = create_async_engine( + "postgresql+asyncpg://user:password@localhost/tmp", + connect_args={"server_settings": {"jit": "off"}}, + ) + +.. seealso:: + + https://github.com/MagicStack/asyncpg/issues/727 + +""" # noqa + +from __future__ import annotations + +from collections import deque +import decimal +import json as _py_json +import re +import time + +from . import json +from . import ranges +from .array import ARRAY as PGARRAY +from .base import _DECIMAL_TYPES +from .base import _FLOAT_TYPES +from .base import _INT_TYPES +from .base import ENUM +from .base import INTERVAL +from .base import OID +from .base import PGCompiler +from .base import PGDialect +from .base import PGExecutionContext +from .base import PGIdentifierPreparer +from .base import REGCLASS +from .base import REGCONFIG +from .types import BIT +from .types import BYTEA +from .types import CITEXT +from ... import exc +from ... import pool +from ... import util +from ...connectors.asyncio import AsyncAdapt_terminate +from ...engine import AdaptedConnection +from ...engine import processors +from ...sql import sqltypes +from ...util.concurrency import asyncio +from ...util.concurrency import await_fallback +from ...util.concurrency import await_only + + +class AsyncpgARRAY(PGARRAY): + render_bind_cast = True + + +class AsyncpgString(sqltypes.String): + render_bind_cast = True + + +class AsyncpgREGCONFIG(REGCONFIG): + render_bind_cast = True + + +class AsyncpgTime(sqltypes.Time): + render_bind_cast = True + + +class AsyncpgBit(BIT): + render_bind_cast = True + + +class AsyncpgByteA(BYTEA): + render_bind_cast = True + + +class AsyncpgDate(sqltypes.Date): + render_bind_cast = True + + +class AsyncpgDateTime(sqltypes.DateTime): + render_bind_cast = True + + +class AsyncpgBoolean(sqltypes.Boolean): + render_bind_cast = True + + +class AsyncPgInterval(INTERVAL): + render_bind_cast = True + + @classmethod + def adapt_emulated_to_native(cls, interval, **kw): + return AsyncPgInterval(precision=interval.second_precision) + + +class AsyncPgEnum(ENUM): + render_bind_cast = True + + +class AsyncpgInteger(sqltypes.Integer): + render_bind_cast = True + + +class AsyncpgSmallInteger(sqltypes.SmallInteger): + render_bind_cast = True + + +class AsyncpgBigInteger(sqltypes.BigInteger): + render_bind_cast = True + + +class AsyncpgJSON(json.JSON): + def result_processor(self, dialect, coltype): + return None + + +class AsyncpgJSONB(json.JSONB): + def result_processor(self, dialect, coltype): + return None + + +class AsyncpgJSONIndexType(sqltypes.JSON.JSONIndexType): + pass + + +class AsyncpgJSONIntIndexType(sqltypes.JSON.JSONIntIndexType): + __visit_name__ = "json_int_index" + + render_bind_cast = True + + +class AsyncpgJSONStrIndexType(sqltypes.JSON.JSONStrIndexType): + __visit_name__ = "json_str_index" + + render_bind_cast = True + + +class AsyncpgJSONPathType(json.JSONPathType): + def bind_processor(self, dialect): + def process(value): + if isinstance(value, str): + # If it's already a string assume that it's in json path + # format.

postgresql + :name: PostgreSQL + :normal_support: 9.6+ + :best_effort: 9+ + +.. _postgresql_sequences: + +Sequences/SERIAL/IDENTITY +------------------------- + +PostgreSQL supports sequences, and SQLAlchemy uses these as the default means +of creating new primary key values for integer-based primary key columns. When +creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for +integer-based primary key columns, which generates a sequence and server side +default corresponding to the column. + +To specify a specific named sequence to be used for primary key generation, +use the :func:`~sqlalchemy.schema.Sequence` construct:: + + Table( + "sometable", + metadata, + Column( + "id", Integer, Sequence("some_id_seq", start=1), primary_key=True + ), + ) + +When SQLAlchemy issues a single INSERT statement, to fulfill the contract of +having the "last insert identifier" available, a RETURNING clause is added to +the INSERT statement which specifies the primary key columns should be +returned after the statement completes. The RETURNING functionality only takes +place if PostgreSQL 8.2 or later is in use. As a fallback approach, the +sequence, whether specified explicitly or implicitly via ``SERIAL``, is +executed independently beforehand, the returned value to be used in the +subsequent insert. Note that when an +:func:`~sqlalchemy.sql.expression.insert()` construct is executed using +"executemany" semantics, the "last inserted identifier" functionality does not +apply; no RETURNING clause is emitted nor is the sequence pre-executed in this +case. + + +PostgreSQL 10 and above IDENTITY columns +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +PostgreSQL 10 and above have a new IDENTITY feature that supersedes the use +of SERIAL. The :class:`_schema.Identity` construct in a +:class:`_schema.Column` can be used to control its behavior:: + + from sqlalchemy import Table, Column, MetaData, Integer, Computed + + metadata = MetaData() + + data = Table( + "data", + metadata, + Column( + "id", Integer, Identity(start=42, cycle=True), primary_key=True + ), + Column("data", String), + ) + +The CREATE TABLE for the above :class:`_schema.Table` object would be: + +.. sourcecode:: sql + + CREATE TABLE data ( + id INTEGER GENERATED BY DEFAULT AS IDENTITY (START WITH 42 CYCLE), + data VARCHAR, + PRIMARY KEY (id) + ) + +.. versionchanged:: 1.4 Added :class:`_schema.Identity` construct + in a :class:`_schema.Column` to specify the option of an autoincrementing + column. + +.. note:: + + Previous versions of SQLAlchemy did not have built-in support for rendering + of IDENTITY, and could use the following compilation hook to replace + occurrences of SERIAL with IDENTITY:: + + from sqlalchemy.schema import CreateColumn + from sqlalchemy.ext.compiler import compiles + + + @compiles(CreateColumn, "postgresql") + def use_identity(element, compiler, **kw): + text = compiler.visit_create_column(element, **kw) + text = text.replace("SERIAL", "INT GENERATED BY DEFAULT AS IDENTITY") + return text + + Using the above, a table such as:: + + t = Table( + "t", m, Column("id", Integer, primary_key=True), Column("data", String) + ) + + Will generate on the backing database as: + + .. sourcecode:: sql + + CREATE TABLE t ( + id INT GENERATED BY DEFAULT AS IDENTITY, + data VARCHAR, + PRIMARY KEY (id) + ) + +.. _postgresql_ss_cursors: + +Server Side Cursors +------------------- + +Server-side cursor support is available for the psycopg2, asyncpg +dialects and may also be available in others. + +Server side cursors are enabled on a per-statement basis by using the +:paramref:`.Connection.execution_options.stream_results` connection execution +option:: + + with engine.connect() as conn: + result = conn.execution_options(stream_results=True).execute( + text("select * from table") + ) + +Note that some kinds of SQL statements may not be supported with +server side cursors; generally, only SQL statements that return rows should be +used with this option. + +.. deprecated:: 1.4 The dialect-level server_side_cursors flag is deprecated + and will be removed in a future release. Please use the + :paramref:`_engine.Connection.stream_results` execution option for + unbuffered cursor support. + +.. seealso:: + + :ref:`engine_stream_results` + +.. _postgresql_isolation_level: + +Transaction Isolation Level +--------------------------- + +Most SQLAlchemy dialects support setting of transaction isolation level +using the :paramref:`_sa.create_engine.isolation_level` parameter +at the :func:`_sa.create_engine` level, and at the :class:`_engine.Connection` +level via the :paramref:`.Connection.execution_options.isolation_level` +parameter. + +For PostgreSQL dialects, this feature works either by making use of the +DBAPI-specific features, such as psycopg2's isolation level flags which will +embed the isolation level setting inline with the ``"BEGIN"`` statement, or for +DBAPIs with no direct support by emitting ``SET SESSION CHARACTERISTICS AS +TRANSACTION ISOLATION LEVEL `` ahead of the ``"BEGIN"`` statement +emitted by the DBAPI. For the special AUTOCOMMIT isolation level, +DBAPI-specific techniques are used which is typically an ``.autocommit`` +flag on the DBAPI connection object. + +To set isolation level using :func:`_sa.create_engine`:: + + engine = create_engine( + "postgresql+pg8000://scott:tiger@localhost/test", + isolation_level="REPEATABLE READ", + ) + +To set using per-connection execution options:: + + with engine.connect() as conn: + conn = conn.execution_options(isolation_level="REPEATABLE READ") + with conn.begin(): + ... # work with transaction + +There are also more options for isolation level configurations, such as +"sub-engine" objects linked to a main :class:`_engine.Engine` which each apply +different isolation level settings. See the discussion at +:ref:`dbapi_autocommit` for background. + +Valid values for ``isolation_level`` on most PostgreSQL dialects include: + +* ``READ COMMITTED`` +* ``READ UNCOMMITTED`` +* ``REPEATABLE READ`` +* ``SERIALIZABLE`` +* ``AUTOCOMMIT`` + +.. seealso:: + + :ref:`dbapi_autocommit` + + :ref:`postgresql_readonly_deferrable` + + :ref:`psycopg2_isolation_level` + + :ref:`pg8000_isolation_level` + +.. _postgresql_readonly_deferrable: + +Setting READ ONLY / DEFERRABLE +------------------------------ + +Most PostgreSQL dialects support setting the "READ ONLY" and "DEFERRABLE" +characteristics of the transaction, which is in addition to the isolation level +setting. These two attributes can be established either in conjunction with or +independently of the isolation level by passing the ``postgresql_readonly`` and +``postgresql_deferrable`` flags with +:meth:`_engine.Connection.execution_options`. The example below illustrates +passing the ``"SERIALIZABLE"`` isolation level at the same time as setting +"READ ONLY" and "DEFERRABLE":: + + with engine.connect() as conn: + conn = conn.execution_options( + isolation_level="SERIALIZABLE", + postgresql_readonly=True, + postgresql_deferrable=True, + ) + with conn.begin(): + ... # work with transaction + +Note that some DBAPIs such as asyncpg only support "readonly" with +SERIALIZABLE isolation. + +.. versionadded:: 1.4 added support for the ``postgresql_readonly`` + and ``postgresql_deferrable`` execution options. + +.. _postgresql_reset_on_return: + +Temporary Table / Resource Reset for Connection Pooling +------------------------------------------------------- + +The :class:`.QueuePool` connection pool implementation used +by the SQLAlchemy :class:`.Engine` object includes +:ref:`reset on return ` behavior that will invoke +the DBAPI ``.rollback()`` method when connections are returned to the pool. +While this rollback will clear out the immediate state used by the previous +transaction, it does not cover a wider range of session-level state, including +temporary tables as well as other server state such as prepared statement +handles and statement caches. The PostgreSQL database includes a variety +of commands which may be used to reset this state, including +``DISCARD``, ``RESET``, ``DEALLOCATE``, and ``UNLISTEN``. + + +To install +one or more of these commands as the means of performing reset-on-return, +the :meth:`.PoolEvents.reset` event hook may be used, as demonstrated +in the example below. The implementation +will end transactions in progress as well as discard temporary tables +using the ``CLOSE``, ``RESET`` and ``DISCARD`` commands; see the PostgreSQL +documentation for background on what each of these statements do. + +The :paramref:`_sa.create_engine.pool_reset_on_return` parameter +is set to ``None`` so that the custom scheme can replace the default behavior +completely. The custom hook implementation calls ``.rollback()`` in any case, +as it's usually important that the DBAPI's own tracking of commit/rollback +will remain consistent with the state of the transaction:: + + + from sqlalchemy import create_engine + from sqlalchemy import event + + postgresql_engine = create_engine( + "postgresql+psycopg2://scott:tiger@hostname/dbname", + # disable default reset-on-return scheme + pool_reset_on_return=None, + ) + + + @event.listens_for(postgresql_engine, "reset") + def _reset_postgresql(dbapi_connection, connection_record, reset_state): + if not reset_state.terminate_only: + dbapi_connection.execute("CLOSE ALL") + dbapi_connection.execute("RESET ALL") + dbapi_connection.execute("DISCARD TEMP") + + # so that the DBAPI itself knows that the connection has been + # reset + dbapi_connection.rollback() + +.. versionchanged:: 2.0.0b3 Added additional state arguments to + the :meth:`.PoolEvents.reset` event and additionally ensured the event + is invoked for all "reset" occurrences, so that it's appropriate + as a place for custom "reset" handlers. Previous schemes which + use the :meth:`.PoolEvents.checkin` handler remain usable as well. + +.. seealso:: + + :ref:`pool_reset_on_return` - in the :ref:`pooling_toplevel` documentation + +.. _postgresql_alternate_search_path: + +Setting Alternate Search Paths on Connect +------------------------------------------ + +The PostgreSQL ``search_path`` variable refers to the list of schema names +that will be implicitly referenced when a particular table or other +object is referenced in a SQL statement. As detailed in the next section +:ref:`postgresql_schema_reflection`, SQLAlchemy is generally organized around +the concept of keeping this variable at its default value of ``public``, +however, in order to have it set to any arbitrary name or names when connections +are used automatically, the "SET SESSION search_path" command may be invoked +for all connections in a pool using the following event handler, as discussed +at :ref:`schema_set_default_connections`:: + + from sqlalchemy import event + from sqlalchemy import create_engine + + engine = create_engine("postgresql+psycopg2://scott:tiger@host/dbname") + + + @event.listens_for(engine, "connect", insert=True) + def set_search_path(dbapi_connection, connection_record): + existing_autocommit = dbapi_connection.autocommit + dbapi_connection.autocommit = True + cursor = dbapi_connection.cursor() + cursor.execute("SET SESSION search_path='%s'" % schema_name) + cursor.close() + dbapi_connection.autocommit = existing_autocommit + +The reason the recipe is complicated by use of the ``.autocommit`` DBAPI +attribute is so that when the ``SET SESSION search_path`` directive is invoked, +it is invoked outside of the scope of any transaction and therefore will not +be reverted when the DBAPI connection has a rollback. + +.. seealso:: + + :ref:`schema_set_default_connections` - in the :ref:`metadata_toplevel` documentation + +.. _postgresql_schema_reflection: + +Remote-Schema Table Introspection and PostgreSQL search_path +------------------------------------------------------------ + +.. admonition:: Section Best Practices Summarized + + keep the ``search_path`` variable set to its default of ``public``, without + any other schema names. Ensure the username used to connect **does not** + match remote schemas, or ensure the ``"$user"`` token is **removed** from + ``search_path``. For other schema names, name these explicitly + within :class:`_schema.Table` definitions. Alternatively, the + ``postgresql_ignore_search_path`` option will cause all reflected + :class:`_schema.Table` objects to have a :attr:`_schema.Table.schema` + attribute set up. + +The PostgreSQL dialect can reflect tables from any schema, as outlined in +:ref:`metadata_reflection_schemas`. + +In all cases, the first thing SQLAlchemy does when reflecting tables is +to **determine the default schema for the current database connection**. +It does this using the PostgreSQL ``current_schema()`` +function, illustated below using a PostgreSQL client session (i.e. using +the ``psql`` tool): + +.. sourcecode:: sql + + test=> select current_schema(); + current_schema + ---------------- + public + (1 row) + +Above we see that on a plain install of PostgreSQL, the default schema name +is the name ``public``. + +However, if your database username **matches the name of a schema**, PostgreSQL's +default is to then **use that name as the default schema**. Below, we log in +using the username ``scott``. When we create a schema named ``scott``, **it +implicitly changes the default schema**: + +.. sourcecode:: sql + + test=> select current_schema(); + current_schema + ---------------- + public + (1 row) + + test=> create schema scott; + CREATE SCHEMA + test=> select current_schema(); + current_schema + ---------------- + scott + (1 row) + +The behavior of ``current_schema()`` is derived from the +`PostgreSQL search path +`_ +variable ``search_path``, which in modern PostgreSQL versions defaults to this: + +.. sourcecode:: sql + + test=> show search_path; + search_path + ----------------- + "$user", public + (1 row) + +Where above, the ``"$user"`` variable will inject the current username as the +default schema, if one exists. Otherwise, ``public`` is used. + +When a :class:`_schema.Table` object is reflected, if it is present in the +schema indicated by the ``current_schema()`` function, **the schema name assigned +to the ".schema" attribute of the Table is the Python "None" value**. Otherwise, the +".schema" attribute will be assigned the string name of that schema. + +With regards to tables which these :class:`_schema.Table` +objects refer to via foreign key constraint, a decision must be made as to how +the ``.schema`` is represented in those remote tables, in the case where that +remote schema name is also a member of the current ``search_path``. + +By default, the PostgreSQL dialect mimics the behavior encouraged by +PostgreSQL's own ``pg_get_constraintdef()`` builtin procedure. This function +returns a sample definition for a particular foreign key constraint, +omitting the referenced schema name from that definition when the name is +also in the PostgreSQL schema search path. The interaction below +illustrates this behavior: + +.. sourcecode:: sql + + test=> CREATE TABLE test_schema.referred(id INTEGER PRIMARY KEY); + CREATE TABLE + test=> CREATE TABLE referring( + test(> id INTEGER PRIMARY KEY, + test(> referred_id INTEGER REFERENCES test_schema.referred(id)); + CREATE TABLE + test=> SET search_path TO public, test_schema; + test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM + test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n + test-> ON n.oid = c.relnamespace + test-> JOIN pg_catalog.pg_constraint r ON c.oid = r.conrelid + test-> WHERE c.relname='referring' AND r.contype = 'f' + test-> ; + pg_get_constraintdef + --------------------------------------------------- + FOREIGN KEY (referred_id) REFERENCES referred(id) + (1 row) + +Above, we created a table ``referred`` as a member of the remote schema +``test_schema``, however when we added ``test_schema`` to the +PG ``search_path`` and then asked ``pg_get_constraintdef()`` for the +``FOREIGN KEY`` syntax, ``test_schema`` was not included in the output of +the function. + +On the other hand, if we set the search path back to the typical default +of ``public``: + +.. sourcecode:: sql + + test=> SET search_path TO public; + SET + +The same query against ``pg_get_constraintdef()`` now returns the fully +schema-qualified name for us: + +.. sourcecode:: sql + + test=> SELECT pg_catalog.pg_get_constraintdef(r.oid, true) FROM + test-> pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n + test-> ON n.oid = c.relnamespace + test-> JOIN pg_catalog.pg_constraint r ON c.oid = r.conrelid + test-> WHERE c.relname='referring' AND r.contype = 'f'; + pg_get_constraintdef + --------------------------------------------------------------- + FOREIGN KEY (referred_id) REFERENCES test_schema.referred(id) + (1 row) + +SQLAlchemy will by default use the return value of ``pg_get_constraintdef()`` +in order to determine the remote schema name. That is, if our ``search_path`` +were set to include ``test_schema``, and we invoked a table +reflection process as follows:: + + >>> from sqlalchemy import Table, MetaData, create_engine, text + >>> engine = create_engine("postgresql+psycopg2://scott:tiger@localhost/test") + >>> with engine.connect() as conn: + ... conn.execute(text("SET search_path TO test_schema, public")) + ... metadata_obj = MetaData() + ... referring = Table("referring", metadata_obj, autoload_with=conn) + + +The above process would deliver to the :attr:`_schema.MetaData.tables` +collection +``referred`` table named **without** the schema:: + + >>> metadata_obj.tables["referred"].schema is None + True + +To alter the behavior of reflection such that the referred schema is +maintained regardless of the ``search_path`` setting, use the +``postgresql_ignore_search_path`` option, which can be specified as a +dialect-specific argument to both :class:`_schema.Table` as well as +:meth:`_schema.MetaData.reflect`:: + + >>> with engine.connect() as conn: + ... conn.execute(text("SET search_path TO test_schema, public")) + ... metadata_obj = MetaData() + ... referring = Table( + ...

But in fact, there's no need to understand any of it if + you just stick to the simplest use pattern: leave the ``search_path`` set + to its default of ``public`` only, never refer to the name ``public`` as + an explicit schema name otherwise, and refer to all other schema names + explicitly when building up a :class:`_schema.Table` object. The options + described here are only for those users who can't, or prefer not to, stay + within these guidelines. + +.. seealso:: + + :ref:`reflection_schema_qualified_interaction` - discussion of the issue + from a backend-agnostic perspective + + `The Schema Search Path + `_ + - on the PostgreSQL website. + +INSERT/UPDATE...RETURNING +------------------------- + +The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and +``DELETE..RETURNING`` syntaxes. ``INSERT..RETURNING`` is used by default +for single-row INSERT statements in order to fetch newly generated +primary key identifiers. To specify an explicit ``RETURNING`` clause, +use the :meth:`._UpdateBase.returning` method on a per-statement basis:: + + # INSERT..RETURNING + result = ( + table.insert().returning(table.c.col1, table.c.col2).values(name="foo") + ) + print(result.fetchall()) + + # UPDATE..RETURNING + result = ( + table.update() + .returning(table.c.col1, table.c.col2) + .where(table.c.name == "foo") + .values(name="bar") + ) + print(result.fetchall()) + + # DELETE..RETURNING + result = ( + table.delete() + .returning(table.c.col1, table.c.col2) + .where(table.c.name == "foo") + ) + print(result.fetchall()) + +.. _postgresql_insert_on_conflict: + +INSERT...ON CONFLICT (Upsert) +------------------------------ + +Starting with version 9.5, PostgreSQL allows "upserts" (update or insert) of +rows into a table via the ``ON CONFLICT`` clause of the ``INSERT`` statement. A +candidate row will only be inserted if that row does not violate any unique +constraints. In the case of a unique constraint violation, a secondary action +can occur which can be either "DO UPDATE", indicating that the data in the +target row should be updated, or "DO NOTHING", which indicates to silently skip +this row. + +Conflicts are determined using existing unique constraints and indexes. These +constraints may be identified either using their name as stated in DDL, +or they may be inferred by stating the columns and conditions that comprise +the indexes. + +SQLAlchemy provides ``ON CONFLICT`` support via the PostgreSQL-specific +:func:`_postgresql.insert()` function, which provides +the generative methods :meth:`_postgresql.Insert.on_conflict_do_update` +and :meth:`~.postgresql.Insert.on_conflict_do_nothing`: + +.. sourcecode:: pycon+sql + + >>> from sqlalchemy.dialects.postgresql import insert + >>> insert_stmt = insert(my_table).values( + ... id="some_existing_id", data="inserted value" + ... ) + >>> do_nothing_stmt = insert_stmt.on_conflict_do_nothing(index_elements=["id"]) + >>> print(do_nothing_stmt) + {printsql}INSERT INTO my_table (id, data) VALUES (%(id)s, %(data)s) + ON CONFLICT (id) DO NOTHING + {stop} + + >>> do_update_stmt = insert_stmt.on_conflict_do_update( + ... constraint="pk_my_table", set_=dict(data="updated value") + ... ) + >>> print(do_update_stmt) + {printsql}INSERT INTO my_table (id, data) VALUES (%(id)s, %(data)s) + ON CONFLICT ON CONSTRAINT pk_my_table DO UPDATE SET data = %(param_1)s + +.. seealso:: + + `INSERT ..

In this use, + if the constraint has a name, it is used directly. Otherwise, if the + constraint is unnamed, then inference will be used, where the expressions + and optional WHERE clause of the constraint will be spelled out in the + construct. This use is especially convenient + to refer to the named or unnamed primary key of a :class:`_schema.Table` + using the + :attr:`_schema.Table.primary_key` attribute: + + .. sourcecode:: pycon+sql + + >>> do_update_stmt = insert_stmt.on_conflict_do_update( + ... constraint=my_table.primary_key, set_=dict(data="updated value") + ... ) + >>> print(do_update_stmt) + {printsql}INSERT INTO my_table (id, data) VALUES (%(id)s, %(data)s) + ON CONFLICT (id) DO UPDATE SET data = %(param_1)s + +The SET Clause +^^^^^^^^^^^^^^^ + +``ON CONFLICT...DO UPDATE`` is used to perform an update of the already +existing row, using any combination of new values as well as values +from the proposed insertion.

For simple cases with some +degree of cross-backend compatibility, the :meth:`.Operators.match` operator +may also be used. + +.. _postgresql_simple_match: + +Simple plain text matching with ``match()`` +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The :meth:`.Operators.match` operator provides for cross-compatible simple +text matching. For the PostgreSQL backend, it's hardcoded to generate +an expression using the ``@@`` operator in conjunction with the +``plainto_tsquery()`` PostgreSQL function. + +On the PostgreSQL dialect, an expression like the following:: + + select(sometable.c.text.match("search string")) + +would emit to the database: + +.. sourcecode:: sql + + SELECT text @@ plainto_tsquery('search string') FROM table + +Above, passing a plain string to :meth:`.Operators.match` will automatically +make use of ``plainto_tsquery()`` to specify the type of tsquery. This +establishes basic database cross-compatibility for :meth:`.Operators.match` +with other backends. + +.. versionchanged:: 2.0 The default tsquery generation function used by the + PostgreSQL dialect with :meth:`.Operators.match` is ``plainto_tsquery()``. + + To render exactly what was rendered in 1.4, use the following form:: + + from sqlalchemy import func + + select(sometable.c.text.bool_op("@@")(func.to_tsquery("search string"))) + + Which would emit: + + .. sourcecode:: sql + + SELECT text @@ to_tsquery('search string') FROM table + +Using PostgreSQL full text functions and operators directly +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Text search operations beyond the simple use of :meth:`.Operators.match` +may make use of the :data:`.func` namespace to generate PostgreSQL full-text +functions, in combination with :meth:`.Operators.bool_op` to generate +any boolean operator. + +For example, the query:: + + select(func.to_tsquery("cat").bool_op("@>")(func.to_tsquery("cat & rat"))) + +would generate: + +.. sourcecode:: sql + + SELECT to_tsquery('cat') @> to_tsquery('cat & rat') + + +The :class:`_postgresql.TSVECTOR` type can provide for explicit CAST:: + + from sqlalchemy.dialects.postgresql import TSVECTOR + from sqlalchemy import select, cast + + select(cast("some text", TSVECTOR)) + +produces a statement equivalent to: + +.. sourcecode:: sql + + SELECT CAST('some text' AS TSVECTOR) AS anon_1 + +The ``func`` namespace is augmented by the PostgreSQL dialect to set up +correct argument and return types for most full text search functions. +These functions are used automatically by the :attr:`_sql.func` namespace +assuming the ``sqlalchemy.dialects.postgresql`` package has been imported, +or :func:`_sa.create_engine` has been invoked using a ``postgresql`` +dialect.

This can be used to produce the +``SELECT ... FROM ONLY``, ``UPDATE ONLY ...``, and ``DELETE FROM ONLY ...`` +syntaxes. It uses SQLAlchemy's hints mechanism:: + + # SELECT ... FROM ONLY ... + result = table.select().with_hint(table, "ONLY", "postgresql") + print(result.fetchall()) + + # UPDATE ONLY ... + table.update(values=dict(foo="bar")).with_hint( + "ONLY", dialect_name="postgresql" + ) + + # DELETE FROM ONLY ... + table.delete().with_hint("ONLY", dialect_name="postgresql") + +.. _postgresql_indexes: + +PostgreSQL-Specific Index Options +--------------------------------- + +Several extensions to the :class:`.Index` construct are available, specific +to the PostgreSQL dialect. + +.. _postgresql_covering_indexes: + +Covering Indexes +^^^^^^^^^^^^^^^^ + +A covering index includes additional columns that are not part of the index key +but are stored in the index, allowing PostgreSQL to satisfy queries using only +the index without accessing the table (an "index-only scan"). This is +indicated on the index using the ``INCLUDE`` clause. The +``postgresql_include`` option for :class:`.Index` (as well as +:class:`.UniqueConstraint`) renders ``INCLUDE(colname)`` for the given string +names:: + + Index("my_index", table.c.x, postgresql_include=["y"]) + +would render the index as ``CREATE INDEX my_index ON table (x) INCLUDE (y)`` + +Note that this feature requires PostgreSQL 11 or later. + +.. seealso:: + + :ref:`postgresql_constraint_options_include` - the same feature implemented + for :class:`.UniqueConstraint` + +.. versionadded:: 1.4 - support for covering indexes with :class:`.Index`. + support for :class:`.UniqueConstraint` was in 2.0.41 + +.. _postgresql_partial_indexes: + +Partial Indexes +^^^^^^^^^^^^^^^ + +Partial indexes add criterion to the index definition so that the index is +applied to a subset of rows. These can be specified on :class:`.Index` +using the ``postgresql_where`` keyword argument:: + + Index("my_index", my_table.c.id, postgresql_where=my_table.c.value > 10) + +.. _postgresql_operator_classes: + +Operator Classes +^^^^^^^^^^^^^^^^ + +PostgreSQL allows the specification of an *operator class* for each column of +an index (see +https://www.postgresql.org/docs/current/interactive/indexes-opclass.html). +The :class:`.Index` construct allows these to be specified via the +``postgresql_ops`` keyword argument:: + + Index( + "my_index", + my_table.c.id, + my_table.c.data, + postgresql_ops={"data": "text_pattern_ops", "id": "int4_ops"}, + ) + +Note that the keys in the ``postgresql_ops`` dictionaries are the +"key" name of the :class:`_schema.Column`, i.e. the name used to access it from +the ``.c`` collection of :class:`_schema.Table`, which can be configured to be +different than the actual name of the column as expressed in the database. + +If ``postgresql_ops`` is to be used against a complex SQL expression such +as a function call, then to apply to the column it must be given a label +that is identified in the dictionary by name, e.g.:: + + Index( + "my_index", + my_table.c.id, + func.lower(my_table.c.data).label("data_lower"), + postgresql_ops={"data_lower": "text_pattern_ops", "id": "int4_ops"}, + ) + +Operator classes are also supported by the +:class:`_postgresql.ExcludeConstraint` construct using the +:paramref:`_postgresql.ExcludeConstraint.ops` parameter. See that parameter for +details. + +.. versionadded:: 1.3.21 added support for operator classes with + :class:`_postgresql.ExcludeConstraint`. + + +Index Types +^^^^^^^^^^^ + +PostgreSQL provides several index types: B-Tree, Hash, GiST, and GIN, as well +as the ability for users to create their own (see +https://www.postgresql.org/docs/current/static/indexes-types.html). These can be +specified on :class:`.Index` using the ``postgresql_using`` keyword argument:: + + Index("my_index", my_table.c.data, postgresql_using="gin") + +The value passed to the keyword argument will be simply passed through to the +underlying CREATE INDEX command, so it *must* be a valid index type for your +version of PostgreSQL. + +.. _postgresql_index_storage: + +Index Storage Parameters +^^^^^^^^^^^^^^^^^^^^^^^^ + +PostgreSQL allows storage parameters to be set on indexes. The storage +parameters available depend on the index method used by the index. Storage +parameters can be specified on :class:`.Index` using the ``postgresql_with`` +keyword argument:: + + Index("my_index", my_table.c.data, postgresql_with={"fillfactor": 50}) + +PostgreSQL allows to define the tablespace in which to create the index. +The tablespace can be specified on :class:`.Index` using the +``postgresql_tablespace`` keyword argument:: + + Index("my_index", my_table.c.data, postgresql_tablespace="my_tablespace") + +Note that the same option is available on :class:`_schema.Table` as well. + +.. _postgresql_index_concurrently: + +Indexes with CONCURRENTLY +^^^^^^^^^^^^^^^^^^^^^^^^^ + +The PostgreSQL index option CONCURRENTLY is supported by passing the +flag ``postgresql_concurrently`` to the :class:`.Index` construct:: + + tbl = Table("testtbl", m, Column("data", Integer)) + + idx1 = Index("test_idx1", tbl.c.data, postgresql_concurrently=True) + +The above index construct will render DDL for CREATE INDEX, assuming +PostgreSQL 8.2 or higher is detected or for a connection-less dialect, as: + +.. sourcecode:: sql + + CREATE INDEX CONCURRENTLY test_idx1 ON testtbl (data) + +For DROP INDEX, assuming PostgreSQL 9.2 or higher is detected or for +a connection-less dialect, it will emit: + +.. sourcecode:: sql + + DROP INDEX CONCURRENTLY test_idx1 + +When using CONCURRENTLY, the PostgreSQL database requires that the statement +be invoked outside of a transaction block. The Python DBAPI enforces that +even for a single statement, a transaction is present, so to use this +construct, the DBAPI's "autocommit" mode must be used:: + + metadata = MetaData() + table = Table("foo", metadata, Column("id", String)) + index = Index("foo_idx", table.c.id, postgresql_concurrently=True) + + with engine.connect() as conn: + with conn.execution_options(isolation_level="AUTOCOMMIT"): + table.create(conn) + +.. seealso:: + + :ref:`postgresql_isolation_level` + +.. _postgresql_index_reflection: + +PostgreSQL Index Reflection +--------------------------- + +The PostgreSQL database creates a UNIQUE INDEX implicitly whenever the +UNIQUE CONSTRAINT construct is used. When inspecting a table using +:class:`_reflection.Inspector`, the :meth:`_reflection.Inspector.get_indexes` +and the :meth:`_reflection.Inspector.get_unique_constraints` +will report on these +two constructs distinctly; in the case of the index, the key +``duplicates_constraint`` will be present in the index entry if it is +detected as mirroring a constraint. When performing reflection using +``Table(..., autoload_with=engine)``, the UNIQUE INDEX is **not** returned +in :attr:`_schema.Table.indexes` when it is detected as mirroring a +:class:`.UniqueConstraint` in the :attr:`_schema.Table.constraints` collection +. + +Special Reflection Options +-------------------------- + +The :class:`_reflection.Inspector` +used for the PostgreSQL backend is an instance +of :class:`.PGInspector`, which offers additional methods:: + + from sqlalchemy import create_engine, inspect + + engine = create_engine("postgresql+psycopg2://localhost/test") + insp = inspect(engine) # will be a PGInspector + + print(insp.get_enums()) + +.. autoclass:: PGInspector + :members: + +.. _postgresql_table_options: + +PostgreSQL Table Options +------------------------ + +Several options for CREATE TABLE are supported directly by the PostgreSQL +dialect in conjunction with the :class:`_schema.Table` construct, listed in +the following sections. + +.. seealso:: + + `PostgreSQL CREATE TABLE options + `_ - + in the PostgreSQL documentation. + +``INHERITS`` +^^^^^^^^^^^^ + +Specifies one or more parent tables from which this table inherits columns and +constraints, enabling table inheritance hierarchies in PostgreSQL. + +:: + + Table("some_table", metadata, ..., postgresql_inherits="some_supertable") + + Table("some_table", metadata, ..., postgresql_inherits=("t1", "t2", ...)) + +``ON COMMIT`` +^^^^^^^^^^^^^ + +Controls the behavior of temporary tables at transaction commit, with options +to preserve rows, delete rows, or drop the table. + +:: + + Table("some_table", metadata, ..., postgresql_on_commit="PRESERVE ROWS") + +``PARTITION BY`` +^^^^^^^^^^^^^^^^ + +Declares the table as a partitioned table using the specified partitioning +strategy (RANGE, LIST, or HASH) on the given column(s). + +:: + + Table( + "some_table", + metadata, + ..., + postgresql_partition_by="LIST (part_column)", + ) + +``TABLESPACE`` +^^^^^^^^^^^^^^ + +Specifies the tablespace where the table will be stored, allowing control over +the physical location of table data on disk. + +:: + + Table("some_table", metadata, ..., postgresql_tablespace="some_tablespace") + +The above option is also available on the :class:`.Index` construct. + +``USING`` +^^^^^^^^^ + +Specifies the table access method to use for storing table data, such as +``heap`` (the default) or other custom access methods. + +:: + + Table("some_table", metadata, ..., postgresql_using="heap") + +.. versionadded:: 2.0.26 + +``WITH OIDS`` +^^^^^^^^^^^^^ + +Enables the legacy OID (object identifier) system column for the table, which +assigns a unique identifier to each row. + +:: + + Table("some_table", metadata, ..., postgresql_with_oids=True) + +``WITHOUT OIDS`` +^^^^^^^^^^^^^^^^ + +Explicitly disables the OID system column for the table (the default behavior +in modern PostgreSQL versions). + +:: + + Table("some_table", metadata, ..., postgresql_with_oids=False) + +.. _postgresql_constraint_options: + +PostgreSQL Constraint Options +----------------------------- + +The following sections indicate options which are supported by the PostgreSQL +dialect in conjunction with selected constraint constructs. + + +``NOT VALID`` +^^^^^^^^^^^^^ + +Allows a constraint to be added without validating existing rows, improving +performance when adding constraints to large tables. This option applies +towards CHECK and FOREIGN KEY constraints when the constraint is being added +to an existing table via ALTER TABLE, and has the effect that existing rows +are not scanned during the ALTER operation against the constraint being added. + +When using a SQL migration tool such as `Alembic `_ +that renders ALTER TABLE constructs, the ``postgresql_not_valid`` argument +may be specified as an additional keyword argument within the operation +that creates the constraint, as in the following Alembic example:: + + def update(): + op.create_foreign_key( + "fk_user_address", + "address", + "user", + ["user_id"], + ["id"], + postgresql_not_valid=True, + ) + +The keyword is ultimately accepted directly by the +:class:`_schema.CheckConstraint`, :class:`_schema.ForeignKeyConstraint` +and :class:`_schema.ForeignKey` constructs; when using a tool like +Alembic, dialect-specific keyword arguments are passed through to +these constructs from the migration operation directives:: + + CheckConstraint("some_field IS NOT NULL", postgresql_not_valid=True) + + ForeignKeyConstraint( + ["some_id"], ["some_table.some_id"], postgresql_not_valid=True + ) + +.. versionadded:: 1.4.32 + +.. seealso:: + + `PostgreSQL ALTER TABLE options + `_ - + in the PostgreSQL documentation. + +.. _postgresql_constraint_options_include: + +``INCLUDE`` +^^^^^^^^^^^ + +This keyword is applicable to both a ``UNIQUE`` constraint as well as an +``INDEX``. The ``postgresql_include`` option available for +:class:`.UniqueConstraint` as well as :class:`.Index` creates a covering index +by including additional columns in the underlying index without making them +part of the key constraint. This option adds one or more columns as a "payload" +to the index created automatically by PostgreSQL for the constraint. For +example, the following table definition:: + + Table( + "mytable", + metadata, + Column("id", Integer, nullable=False), + Column("value", Integer, nullable=False), + UniqueConstraint("id", postgresql_include=["value"]), + ) + +would produce the DDL statement + +.. sourcecode:: sql + + CREATE TABLE mytable ( + id INTEGER NOT NULL, + value INTEGER NOT NULL, + UNIQUE (id) INCLUDE (value) + ) + +Note that this feature requires PostgreSQL 11 or later. + +.. versionadded:: 2.0.41 - added support for ``postgresql_include`` to + :class:`.UniqueConstraint`, to complement the existing feature in + :class:`.Index`. + +.. seealso:: + + :ref:`postgresql_covering_indexes` - background on ``postgresql_include`` + for the :class:`.Index` construct. + + +Column list with foreign key ``ON DELETE SET`` actions +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Allows selective column updates when a foreign key action is triggered, limiting +which columns are set to NULL or DEFAULT upon deletion of a referenced row. +This applies to :class:`.ForeignKey` and :class:`.ForeignKeyConstraint`, the +:paramref:`.ForeignKey.ondelete` parameter will accept on the PostgreSQL +backend only a string list of column names inside parenthesis, following the +``SET NULL`` or ``SET DEFAULT`` phrases, which will limit the set of columns +that are subject to the action:: + + fktable = Table( + "fktable", + metadata, + Column("tid", Integer), + Column("id", Integer), + Column("fk_id_del_set_null", Integer), + ForeignKeyConstraint( + columns=["tid", "fk_id_del_set_null"], + refcolumns=[pktable.c.tid, pktable.c.id], + ondelete="SET NULL (fk_id_del_set_null)", + ), + ) + +.. versionadded:: 2.0.40 + + +.. _postgresql_table_valued_overview: + +Table values, Table and Column valued functions, Row and Tuple objects +----------------------------------------------------------------------- + +PostgreSQL makes great use of modern SQL forms such as table-valued functions, +tables and rows as values. These constructs are commonly used as part +of PostgreSQL's support for complex datatypes such as JSON, ARRAY, and other +datatypes. SQLAlchemy's SQL expression language has native support for +most table-valued and row-valued forms. + +.. _postgresql_table_valued: + +Table-Valued Functions +^^^^^^^^^^^^^^^^^^^^^^^ + +Many PostgreSQL built-in functions are intended to be used in the FROM clause +of a SELECT statement, and are capable of returning table rows or sets of table +rows. A large portion of PostgreSQL's JSON functions for example such as +``json_array_elements()``, ``json_object_keys()``, ``json_each_text()``, +``json_each()``, ``json_to_record()``, ``json_populate_recordset()`` use such +forms. These classes of SQL function calling forms in SQLAlchemy are available +using the :meth:`_functions.FunctionElement.table_valued` method in conjunction +with :class:`_functions.Function` objects generated from the :data:`_sql.func` +namespace. + +Examples from PostgreSQL's reference documentation follow below: + +* ``json_each()``: + + .. sourcecode:: pycon+sql + + >>> from sqlalchemy import select, func + >>> stmt = select( + ... func.json_each('{"a":"foo", "b":"bar"}').table_valued("key", "value") + ... ) + >>> print(stmt) + {printsql}SELECT anon_1.key, anon_1.value + FROM json_each(:json_each_1) AS anon_1 + +* ``json_populate_record()``: + + .. sourcecode:: pycon+sql + + >>> from sqlalchemy import select, func, literal_column + >>> stmt = select( + ... func.json_populate_record( + ... literal_column("null::myrowtype"), '{"a":1,"b":2}' + ... ).table_valued("a", "b", name="x") + ... ) + >>> print(stmt) + {printsql}SELECT x.a, x.b + FROM json_populate_record(null::myrowtype, :json_populate_record_1) AS x + +* ``json_to_record()`` - this form uses a PostgreSQL specific form of derived + columns in the alias, where we may make use of :func:`_sql.column` elements with + types to produce them. The :meth:`_functions.FunctionElement.table_valued` + method produces a :class:`_sql.TableValuedAlias` construct, and the method + :meth:`_sql.TableValuedAlias.render_derived` method sets up the derived + columns specification: + + .. sourcecode:: pycon+sql + + >>> from sqlalchemy import select, func, column, Integer, Text + >>> stmt = select( + ... func.json_to_record('{"a":1,"b":[1,2,3],"c":"bar"}') + ... .table_valued( + ... column("a", Integer), + ... column("b", Text), + ... column("d", Text), + ... ) + ... .render_derived(name="x", with_types=True) + ... ) + >>> print(stmt) + {printsql}SELECT x.a, x.b, x.d + FROM json_to_record(:json_to_record_1) AS x(a INTEGER, b TEXT, d TEXT) + +* ``WITH ORDINALITY`` - part of the SQL standard, ``WITH ORDINALITY`` adds an + ordinal counter to the output of a function and is accepted by a limited set + of PostgreSQL functions including ``unnest()`` and ``generate_series()``. The + :meth:`_functions.FunctionElement.table_valued` method accepts a keyword + parameter ``with_ordinality`` for this purpose, which accepts the string name + that will be applied to the "ordinality" column: + + .. sourcecode:: pycon+sql + + >>> from sqlalchemy import select, func + >>> stmt = select( + ... func.generate_series(4, 1, -1) + ... .table_valued("value", with_ordinality="ordinality") + ... .render_derived() + ... ) + >>> print(stmt) + {printsql}SELECT anon_1.value, anon_1.ordinality + FROM generate_series(:generate_series_1, :generate_series_2, :generate_series_3) + WITH ORDINALITY AS anon_1(value, ordinality) + +.. versionadded:: 1.4.0b2 + +.. seealso:: + + :ref:`tutorial_functions_table_valued` - in the :ref:`unified_tutorial` + +.. _postgresql_column_valued: + +Column Valued Functions +^^^^^^^^^^^^^^^^^^^^^^^ + +Similar to the table valued function, a column valued function is present +in the FROM clause, but delivers itself to the columns clause as a single +scalar value. PostgreSQL functions such as ``json_array_elements()``, +``unnest()`` and ``generate_series()`` may use this form. Column valued functions are available using the +:meth:`_functions.FunctionElement.column_valued` method of :class:`_functions.FunctionElement`: + +* ``json_array_elements()``: + + .. sourcecode:: pycon+sql + + >>> from sqlalchemy import select, func + >>> stmt = select( + ... func.json_array_elements('["one", "two"]').column_valued("x") + ... ) + >>> print(stmt) + {printsql}SELECT x + FROM json_array_elements(:json_array_elements_1) AS x + +* ``unnest()`` - in order to generate a PostgreSQL ARRAY literal, the + :func:`_postgresql.array` construct may be used: + + .. sourcecode:: pycon+sql + + >>> from sqlalchemy.dialects.postgresql import array + >>> from sqlalchemy import select, func + >>> stmt = select(func.unnest(array([1, 2])).column_valued()) + >>> print(stmt) + {printsql}SELECT anon_1 + FROM unnest(ARRAY[%(param_1)s, %(param_2)s]) AS anon_1 + + The function can of course be used against an existing table-bound column + that's of type :class:`_types.ARRAY`: + + .. sourcecode:: pycon+sql + + >>> from sqlalchemy import table, column, ARRAY, Integer + >>> from sqlalchemy import select, func + >>> t = table("t", column("value", ARRAY(Integer))) + >>> stmt = select(func.unnest(t.c.value).column_valued("unnested_value")) + >>> print(stmt) + {printsql}SELECT unnested_value + FROM unnest(t.value) AS unnested_value + +.. seealso:: + + :ref:`tutorial_functions_column_valued` - in the :ref:`unified_tutorial` + + +Row Types +^^^^^^^^^ + +Built-in support for rendering a ``ROW`` may be approximated using +``func.ROW`` with the :attr:`_sa.func` namespace, or by using the +:func:`_sql.tuple_` construct: + +.. sourcecode:: pycon+sql + + >>> from sqlalchemy import table, column, func, tuple_ + >>> t = table("t", column("id"), column("fk")) + >>> stmt = ( + ... t.select() + ... .where(tuple_(t.c.id, t.c.fk) > (1, 2)) + ... .where(func.ROW(t.c.id, t.c.fk) < func.ROW(3, 7)) + ... ) + >>> print(stmt) + {printsql}SELECT t.id, t.fk + FROM t + WHERE (t.id, t.fk) > (:param_1, :param_2) AND ROW(t.id, t.fk) < ROW(:ROW_1, :ROW_2) + +.. seealso:: + + `PostgreSQL Row Constructors + `_ + + `PostgreSQL Row Constructor Comparison + `_ + +Table Types passed to Functions +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +PostgreSQL supports passing a table as an argument to a function, which is +known as a "record" type.

https://pypi.org/project/psycopg/ + +``psycopg`` is the package and module name for version 3 of the ``psycopg`` +database driver, formerly known as ``psycopg2``. This driver is different +enough from its ``psycopg2`` predecessor that SQLAlchemy supports it +via a totally separate dialect; support for ``psycopg2`` is expected to remain +for as long as that package continues to function for modern Python versions, +and also remains the default dialect for the ``postgresql://`` dialect +series. + +The SQLAlchemy ``psycopg`` dialect provides both a sync and an async +implementation under the same dialect name.

+-------------------------- + +Keyword arguments that are specific to the SQLAlchemy psycopg2 dialect +may be passed to :func:`_sa.create_engine()`, and include the following: + + +* ``isolation_level``: This option, available for all PostgreSQL dialects, + includes the ``AUTOCOMMIT`` isolation level when using the psycopg2 + dialect. This option sets the **default** isolation level for the + connection that is set immediately upon connection to the database before + the connection is pooled. This option is generally superseded by the more + modern :paramref:`_engine.Connection.execution_options.isolation_level` + execution option, detailed at :ref:`dbapi_autocommit`. + + .. seealso:: + + :ref:`psycopg2_isolation_level` + + :ref:`dbapi_autocommit` + + +* ``client_encoding``: sets the client encoding in a libpq-agnostic way, + using psycopg2's ``set_client_encoding()`` method. + + .. seealso:: + + :ref:`psycopg2_unicode` + + +* ``executemany_mode``, ``executemany_batch_page_size``, + ``executemany_values_page_size``: Allows use of psycopg2 + extensions for optimizing "executemany"-style queries. See the referenced + section below for details. + + .. seealso:: + + :ref:`psycopg2_executemany_mode` + +.. tip:: + + The above keyword arguments are **dialect** keyword arguments, meaning + that they are passed as explicit keyword arguments to :func:`_sa.create_engine()`:: + + engine = create_engine( + "postgresql+psycopg2://scott:tiger@localhost/test", + isolation_level="SERIALIZABLE", + ) + + These should not be confused with **DBAPI** connect arguments, which + are passed as part of the :paramref:`_sa.create_engine.connect_args` + dictionary and/or are passed in the URL query string, as detailed in + the section :ref:`custom_dbapi_args`. + +.. _psycopg2_ssl: + +SSL Connections +--------------- + +The psycopg2 module has a connection argument named ``sslmode`` for +controlling its behavior regarding secure (SSL) connections. The default is +``sslmode=prefer``; it will attempt an SSL connection and if that fails it +will fall back to an unencrypted connection. ``sslmode=require`` may be used +to ensure that only secure connections are established. Consult the +psycopg2 / libpq documentation for further options that are available. + +Note that ``sslmode`` is specific to psycopg2 so it is included in the +connection URI:: + + engine = sa.create_engine( + "postgresql+psycopg2://scott:tiger@192.168.0.199:5432/test?sslmode=require" + ) + +Unix Domain Connections +------------------------ + +psycopg2 supports connecting via Unix domain connections. When the ``host`` +portion of the URL is omitted, SQLAlchemy passes ``None`` to psycopg2, +which specifies Unix-domain communication rather than TCP/IP communication:: + + create_engine("postgresql+psycopg2://user:password@/dbname") + +By default, the socket file used is to connect to a Unix-domain socket +in ``/tmp``, or whatever socket directory was specified when PostgreSQL +was built. This value can be overridden by passing a pathname to psycopg2, +using ``host`` as an additional keyword argument:: + + create_engine( + "postgresql+psycopg2://user:password@/dbname?host=/var/lib/postgresql" + ) + +.. warning:: The format accepted here allows for a hostname in the main URL + in addition to the "host" query string argument. **When using this URL + format, the initial host is silently ignored**. That is, this URL:: + + engine = create_engine( + "postgresql+psycopg2://user:password@myhost1/dbname?host=myhost2" + ) + + Above, the hostname ``myhost1`` is **silently ignored and discarded.** The + host which is connected is the ``myhost2`` host. + + This is to maintain some degree of compatibility with PostgreSQL's own URL + format which has been tested to behave the same way and for which tools like + PifPaf hardcode two hostnames. + +.. seealso:: + + `PQconnectdbParams \ + `_ + +.. _psycopg2_multi_host: + +Specifying multiple fallback hosts +----------------------------------- + +psycopg2 supports multiple connection points in the connection string. +When the ``host`` parameter is used multiple times in the query section of +the URL, SQLAlchemy will create a single string of the host and port +information provided to make the connections. Tokens may consist of +``host::port`` or just ``host``; in the latter case, the default port +is selected by libpq. In the example below, three host connections +are specified, for ``HostA::PortA``, ``HostB`` connecting to the default port, +and ``HostC::PortC``:: + + create_engine( + "postgresql+psycopg2://user:password@/dbname?host=HostA:PortA&host=HostB&host=HostC:PortC" + ) + +As an alternative, libpq query string format also may be used; this specifies +``host`` and ``port`` as single query string arguments with comma-separated +lists - the default port can be chosen by indicating an empty value +in the comma separated list:: + + create_engine( + "postgresql+psycopg2://user:password@/dbname?host=HostA,HostB,HostC&port=PortA,,PortC" + ) + +With either URL style, connections to each host is attempted based on a +configurable strategy, which may be configured using the libpq +``target_session_attrs`` parameter. Per libpq this defaults to ``any`` +which indicates a connection to each host is then attempted until a connection is successful. +Other strategies include ``primary``, ``prefer-standby``, etc. The complete +list is documented by PostgreSQL at +`libpq connection strings `_. + +For example, to indicate two hosts using the ``primary`` strategy:: + + create_engine( + "postgresql+psycopg2://user:password@/dbname?host=HostA:PortA&host=HostB&host=HostC:PortC&target_session_attrs=primary" + ) + +.. versionchanged:: 1.4.40 Port specification in psycopg2 multiple host format + is repaired, previously ports were not correctly interpreted in this context. + libpq comma-separated format is also now supported. + +.. versionadded:: 1.3.20 Support for multiple hosts in PostgreSQL connection + string. + +.. seealso:: + + `libpq connection strings `_ - please refer + to this section in the libpq documentation for complete background on multiple host support. + + +Empty DSN Connections / Environment Variable Connections +--------------------------------------------------------- + +The psycopg2 DBAPI can connect to PostgreSQL by passing an empty DSN to the +libpq client library, which by default indicates to connect to a localhost +PostgreSQL database that is open for "trust" connections. This behavior can be +further tailored using a particular set of environment variables which are +prefixed with ``PG_...``, which are consumed by ``libpq`` to take the place of +any or all elements of the connection string. + +For this form, the URL can be passed without any elements other than the +initial scheme:: + + engine = create_engine("postgresql+psycopg2://") + +In the above form, a blank "dsn" string is passed to the ``psycopg2.connect()`` +function which in turn represents an empty DSN passed to libpq. + +.. versionadded:: 1.3.2 support for parameter-less connections with psycopg2. + +.. seealso:: + + `Environment Variables\ + `_ - + PostgreSQL documentation on how to use ``PG_...`` + environment variables for connections. + +.. _psycopg2_execution_options: + +Per-Statement/Connection Execution Options +------------------------------------------- + +The following DBAPI-specific options are respected when used with +:meth:`_engine.Connection.execution_options`, +:meth:`.Executable.execution_options`, +:meth:`_query.Query.execution_options`, +in addition to those not specific to DBAPIs: + +* ``isolation_level`` - Set the transaction isolation level for the lifespan + of a :class:`_engine.Connection` (can only be set on a connection, + not a statement + or query). See :ref:`psycopg2_isolation_level`. + +* ``stream_results`` - Enable or disable usage of psycopg2 server side + cursors - this feature makes use of "named" cursors in combination with + special result handling methods so that result rows are not fully buffered. + Defaults to False, meaning cursors are buffered by default. + +* ``max_row_buffer`` - when using ``stream_results``, an integer value that + specifies the maximum number of rows to buffer at a time. This is + interpreted by the :class:`.BufferedRowCursorResult`, and if omitted the + buffer will grow to ultimately store 1000 rows at a time. + + .. versionchanged:: 1.4 The ``max_row_buffer`` size can now be greater than + 1000, and the buffer will grow to that size. + +.. _psycopg2_batch_mode: + +.. _psycopg2_executemany_mode: + +Psycopg2 Fast Execution Helpers +------------------------------- + +Modern versions of psycopg2 include a feature known as +`Fast Execution Helpers \ +`_, which +have been shown in benchmarking to improve psycopg2's executemany() +performance, primarily with INSERT statements, by at least +an order of magnitude. + +SQLAlchemy implements a native form of the "insert many values" +handler that will rewrite a single-row INSERT statement to accommodate for +many values at once within an extended VALUES clause; this handler is +equivalent to psycopg2's ``execute_values()`` handler; an overview of this +feature and its configuration are at :ref:`engine_insertmanyvalues`. + +.. versionadded:: 2.0 Replaced psycopg2's ``execute_values()`` fast execution + helper with a native SQLAlchemy mechanism known as + :ref:`insertmanyvalues `. + +The psycopg2 dialect retains the ability to use the psycopg2-specific +``execute_batch()`` feature, although it is not expected that this is a widely +used feature. The use of this extension may be enabled using the +``executemany_mode`` flag which may be passed to :func:`_sa.create_engine`:: + + engine = create_engine( + "postgresql+psycopg2://scott:tiger@host/dbname", + executemany_mode="values_plus_batch", + ) + +Possible options for ``executemany_mode`` include: + +* ``values_only`` - this is the default value. SQLAlchemy's native + :ref:`insertmanyvalues ` handler is used for qualifying + INSERT statements, assuming + :paramref:`_sa.create_engine.use_insertmanyvalues` is left at + its default value of ``True``. This handler rewrites simple + INSERT statements to include multiple VALUES clauses so that many + parameter sets can be inserted with one statement. + +* ``'values_plus_batch'``- SQLAlchemy's native + :ref:`insertmanyvalues ` handler is used for qualifying + INSERT statements, assuming + :paramref:`_sa.create_engine.use_insertmanyvalues` is left at its default + value of ``True``. Then, psycopg2's ``execute_batch()`` handler is used for + qualifying UPDATE and DELETE statements when executed with multiple parameter + sets. When using this mode, the :attr:`_engine.CursorResult.rowcount` + attribute will not contain a value for executemany-style executions against + UPDATE and DELETE statements. + +.. versionchanged:: 2.0 Removed the ``'batch'`` and ``'None'`` options + from psycopg2 ``executemany_mode``. Control over batching for INSERT + statements is now configured via the + :paramref:`_sa.create_engine.use_insertmanyvalues` engine-level parameter. + +The term "qualifying statements" refers to the statement being executed +being a Core :func:`_expression.insert`, :func:`_expression.update` +or :func:`_expression.delete` construct, and **not** a plain textual SQL +string or one constructed using :func:`_expression.text`. It also may **not** be +a special "extension" statement such as an "ON CONFLICT" "upsert" statement. +When using the ORM, all insert/update/delete statements used by the ORM flush process +are qualifying. + +The "page size" for the psycopg2 "batch" strategy can be affected +by using the ``executemany_batch_page_size`` parameter, which defaults to +100. + +For the "insertmanyvalues" feature, the page size can be controlled using the +:paramref:`_sa.create_engine.insertmanyvalues_page_size` parameter, +which defaults to 1000. An example of modifying both parameters +is below:: + + engine = create_engine( + "postgresql+psycopg2://scott:tiger@host/dbname", + executemany_mode="values_plus_batch", + insertmanyvalues_page_size=5000, + executemany_batch_page_size=500, + ) + +.. seealso:: + + :ref:`engine_insertmanyvalues` - background on "insertmanyvalues" + + :ref:`tutorial_multiple_parameters` - General information on using the + :class:`_engine.Connection` + object to execute statements in such a way as to make + use of the DBAPI ``.executemany()`` method. + + +.. _psycopg2_unicode: + +Unicode with Psycopg2 +---------------------- + +The psycopg2 DBAPI driver supports Unicode data transparently. + +The client character encoding can be controlled for the psycopg2 dialect +in the following ways: + +* For PostgreSQL 9.1 and above, the ``client_encoding`` parameter may be + passed in the database URL; this parameter is consumed by the underlying + ``libpq`` PostgreSQL client library:: + + engine = create_engine( + "postgresql+psycopg2://user:pass@host/dbname?client_encoding=utf8" + ) + + Alternatively, the above ``client_encoding`` value may be passed using + :paramref:`_sa.create_engine.connect_args` for programmatic establishment with + ``libpq``:: + + engine = create_engine( + "postgresql+psycopg2://user:pass@host/dbname", + connect_args={"client_encoding": "utf8"}, + ) + +* For all PostgreSQL versions, psycopg2 supports a client-side encoding + value that will be passed to database connections when they are first + established. The SQLAlchemy psycopg2 dialect supports this using the + ``client_encoding`` parameter passed to :func:`_sa.create_engine`:: + + engine = create_engine( + "postgresql+psycopg2://user:pass@host/dbname", client_encoding="utf8" + ) + + .. tip:: The above ``client_encoding`` parameter admittedly is very similar + in appearance to usage of the parameter within the + :paramref:`_sa.create_engine.connect_args` dictionary; the difference + above is that the parameter is consumed by psycopg2 and is + passed to the database connection using ``SET client_encoding TO + 'utf8'``; in the previously mentioned style, the parameter is instead + passed through psycopg2 and consumed by the ``libpq`` library. + +* A common way to set up client encoding with PostgreSQL databases is to + ensure it is configured within the server-side postgresql.conf file; + this is the recommended way to set encoding for a server that is + consistently of one encoding in all databases:: + + # postgresql.conf file + + # client_encoding = sql_ascii # actually, defaults to database + # encoding + client_encoding = utf8 + +Transactions +------------ + +The psycopg2 dialect fully supports SAVEPOINT and two-phase commit operations. + +.. _psycopg2_isolation_level: + +Psycopg2 Transaction Isolation Level +------------------------------------- + +As discussed in :ref:`postgresql_isolation_level`, +all PostgreSQL dialects support setting of transaction isolation level +both via the ``isolation_level`` parameter passed to :func:`_sa.create_engine` +, +as well as the ``isolation_level`` argument used by +:meth:`_engine.Connection.execution_options`. When using the psycopg2 dialect +, these +options make use of psycopg2's ``set_isolation_level()`` connection method, +rather than emitting a PostgreSQL directive; this is because psycopg2's +API-level setting is always emitted at the start of each transaction in any +case. + +The psycopg2 dialect supports these constants for isolation level: + +* ``READ COMMITTED`` +* ``READ UNCOMMITTED`` +* ``REPEATABLE READ`` +* ``SERIALIZABLE`` +* ``AUTOCOMMIT`` + +.. seealso:: + + :ref:`postgresql_isolation_level` + + :ref:`pg8000_isolation_level` + + +NOTICE logging +--------------- + +The psycopg2 dialect will log PostgreSQL NOTICE messages +via the ``sqlalchemy.dialects.postgresql`` logger. When this logger +is set to the ``logging.INFO`` level, notice messages will be logged:: + + import logging + + logging.getLogger("sqlalchemy.dialects.postgresql").setLevel(logging.INFO) + +Above, it is assumed that logging is configured externally. If this is not +the case, configuration such as ``logging.basicConfig()`` must be utilized:: + + import logging + + logging.basicConfig() # log messages to stdout + logging.getLogger("sqlalchemy.dialects.postgresql").setLevel(logging.INFO) + +.. seealso:: + + `Logging HOWTO `_ - on the python.org website + +.. _psycopg2_hstore: + +HSTORE type +------------ + +The ``psycopg2`` DBAPI includes an extension to natively handle marshalling of +the HSTORE type. The SQLAlchemy psycopg2 dialect will enable this extension +by default when psycopg2 version 2.4 or greater is used, and +it is detected that the target database has the HSTORE type set up for use. +In other words, when the dialect makes the first +connection, a sequence like the following is performed: + +1. Request the available HSTORE oids using + ``psycopg2.extras.HstoreAdapter.get_oids()``. + If this function returns a list of HSTORE identifiers, we then determine + that the ``HSTORE`` extension is present. + This function is **skipped** if the version of psycopg2 installed is + less than version 2.4. + +2. If the ``use_native_hstore`` flag is at its default of ``True``, and + we've detected that ``HSTORE`` oids are available, the + ``psycopg2.extensions.register_hstore()`` extension is invoked for all + connections. + +The ``register_hstore()`` extension has the effect of **all Python +dictionaries being accepted as parameters regardless of the type of target +column in SQL**. The dictionaries are converted by this extension into a +textual HSTORE expression. If this behavior is not desired, disable the +use of the hstore extension by setting ``use_native_hstore`` to ``False`` as +follows:: + + engine = create_engine( + "postgresql+psycopg2://scott:tiger@localhost/test", + use_native_hstore=False, + ) + +The ``HSTORE`` type is **still supported** when the +``psycopg2.extensions.register_hstore()`` extension is not used. It merely +means that the coercion between Python dictionaries and the HSTORE +string format, on both the parameter side and the result side, will take +place within SQLAlchemy's own marshalling logic, and not that of ``psycopg2`` +which may be more performant. + +""" # noqa +from __future__ import annotations + +import collections.abc as collections_abc +import logging +import re +from typing import cast + +from . import ranges +from ._psycopg_common import _PGDialect_common_psycopg +from ._psycopg_common import _PGExecutionContext_common_psycopg +from .base import PGIdentifierPreparer +from .json import JSON +from .json import JSONB +from ... import types as sqltypes +from ... import util +from ...util import FastIntFlag +from ...util import parse_user_argument_for_enum + +logger = logging.getLogger("sqlalchemy.dialects.postgresql") + + +class _PGJSON(JSON): + def result_processor(self, dialect, coltype): + return None + + +class _PGJSONB(JSONB): + def result_processor(self, dialect, coltype): + return None + + +class _Psycopg2Range(ranges.AbstractSingleRangeImpl): + _psycopg2_range_cls = "none" + + def bind_processor(self, dialect): + psycopg2_Range = getattr( + cast(PGDialect_psycopg2, dialect)._psycopg2_extras, + self._psycopg2_range_cls, + ) + + def to_range(value): + if isinstance(value, ranges.Range): + value = psycopg2_Range( + value.lower, value.upper, value.bounds, value.empty + ) + return value + + return to_range + + def result_processor(self, dialect, coltype): + def to_range(value): + if value is not None: + value = ranges.Range( + value._lower, + value._upper, + bounds=value._bounds if value._bounds else "[)", + empty=not value._bounds, + ) + return value + + return to_range + + +class _Psycopg2NumericRange(_Psycopg2Range): + _psycopg2_range_cls = "NumericRange" + + +class _Psycopg2DateRange(_Psycopg2Range): + _psycopg2_range_cls = "DateRange" + + +class _Psycopg2DateTimeRange(_Psycopg2Range): + _psycopg2_range_cls = "DateTimeRange" + + +class _Psycopg2DateTimeTZRange(_Psycopg2Range): + _psycopg2_range_cls = "DateTimeTZRange" + + +class PGExecutionContext_psycopg2(_PGExecutionContext_common_psycopg): + _psycopg2_fetched_rows = None + + def post_exec(self): + self._log_notices(self.cursor) + + def _log_notices(self, cursor): + # check also that notices is an iterable, after it's already + # established that we will be iterating through it.

A type named ``"BIGINT"``, +``"SPECIAL_INT"`` or even ``"XYZINTQPR"``, will be considered by SQLite to be +of "integer" affinity. However, **the SQLite autoincrement feature, whether +implicitly or explicitly enabled, requires that the name of the column's type +is exactly the string "INTEGER"**. Therefore, if an application uses a type +like :class:`.BigInteger` for a primary key, on SQLite this type will need to +be rendered as the name ``"INTEGER"`` when emitting the initial ``CREATE +TABLE`` statement in order for the autoincrement behavior to be available. + +One approach to achieve this is to use :class:`.Integer` on SQLite +only using :meth:`.TypeEngine.with_variant`:: + + table = Table( + "my_table", + metadata, + Column( + "id", + BigInteger().with_variant(Integer, "sqlite"), + primary_key=True, + ), + ) + +Another is to use a subclass of :class:`.BigInteger` that overrides its DDL +name to be ``INTEGER`` when compiled against SQLite:: + + from sqlalchemy import BigInteger + from sqlalchemy.ext.compiler import compiles + + + class SLBigInteger(BigInteger): + pass + + + @compiles(SLBigInteger, "sqlite") + def bi_c(element, compiler, **kw): + return "INTEGER" + + + @compiles(SLBigInteger) + def bi_c(element, compiler, **kw): + return compiler.visit_BIGINT(element, **kw) + + + table = Table( + "my_table", metadata, Column("id", SLBigInteger(), primary_key=True) + ) + +.. seealso:: + + :meth:`.TypeEngine.with_variant` + + :ref:`sqlalchemy.ext.compiler_toplevel` + + `Datatypes In SQLite Version 3 `_ + +.. _sqlite_transactions: + +Transactions with SQLite and the sqlite3 driver +----------------------------------------------- + +As a file-based database, SQLite's approach to transactions differs from +traditional databases in many ways. Additionally, the ``sqlite3`` driver +standard with Python (as well as the async version ``aiosqlite`` which builds +on top of it) has several quirks, workarounds, and API features in the +area of transaction control, all of which generally need to be addressed when +constructing a SQLAlchemy application that uses SQLite. + +Legacy Transaction Mode with the sqlite3 driver +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The most important aspect of transaction handling with the sqlite3 driver is +that it defaults (which will continue through Python 3.15 before being +removed in Python 3.16) to legacy transactional behavior which does +not strictly follow :pep:`249`. The way in which the driver diverges from the +PEP is that it does not "begin" a transaction automatically as dictated by +:pep:`249` except in the case of DML statements, e.g. INSERT, UPDATE, and +DELETE. Normally, :pep:`249` dictates that a BEGIN must be emitted upon +the first SQL statement of any kind, so that all subsequent operations will +be established within a transaction until ``connection.commit()`` has been +called. The ``sqlite3`` driver, in an effort to be easier to use in +highly concurrent environments, skips this step for DQL (e.g. SELECT) statements, +and also skips it for DDL (e.g. CREATE TABLE etc.) statements for more legacy +reasons. Statements such as SAVEPOINT are also skipped. + +In modern versions of the ``sqlite3`` driver as of Python 3.12, this legacy +mode of operation is referred to as +`"legacy transaction control" `_, and is in +effect by default due to the ``Connection.autocommit`` parameter being set to +the constant ``sqlite3.LEGACY_TRANSACTION_CONTROL``. Prior to Python 3.12, +the ``Connection.autocommit`` attribute did not exist. + +The implications of legacy transaction mode include: + +* **Incorrect support for transactional DDL** - statements like CREATE TABLE, ALTER TABLE, + CREATE INDEX etc. will not automatically BEGIN a transaction if one were not + started already, leading to the changes by each statement being + "autocommitted" immediately unless BEGIN were otherwise emitted first. Very + old (pre Python 3.6) versions of SQLite would also force a COMMIT for these + operations even if a transaction were present, however this is no longer the + case. +* **SERIALIZABLE behavior not fully functional** - SQLite's transaction isolation + behavior is normally consistent with SERIALIZABLE isolation, as it is a file- + based system that locks the database file entirely for write operations, + preventing COMMIT until all reader transactions (and associated file locks) + have completed. However, sqlite3's legacy transaction mode fails to emit BEGIN for SELECT + statements, which causes these SELECT statements to no longer be "repeatable", + failing one of the consistency guarantees of SERIALIZABLE. +* **Incorrect behavior for SAVEPOINT** - as the SAVEPOINT statement does not + imply a BEGIN, a new SAVEPOINT emitted before a BEGIN will function on its + own but fails to participate in the enclosing transaction, meaning a ROLLBACK + of the transaction will not rollback elements that were part of a released + savepoint. + +Legacy transaction mode first existed in order to facilitate working around +SQLite's file locks. Because SQLite relies upon whole-file locks, it is easy to +get "database is locked" errors, particularly when newer features like "write +ahead logging" are disabled. This is a key reason why ``sqlite3``'s legacy +transaction mode is still the default mode of operation; disabling it will +produce behavior that is more susceptible to locked database errors. However +note that **legacy transaction mode will no longer be the default** in a future +Python version (3.16 as of this writing). + +.. _sqlite_enabling_transactions: + +Enabling Non-Legacy SQLite Transactional Modes with the sqlite3 or aiosqlite driver +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Current SQLAlchemy support allows either for setting the +``.Connection.autocommit`` attribute, most directly by using a +:func:`._sa.create_engine` parameter, or if on an older version of Python where +the attribute is not available, using event hooks to control the behavior of +BEGIN. + +* **Enabling modern sqlite3 transaction control via the autocommit connect parameter** (Python 3.12 and above) + + To use SQLite in the mode described at `Transaction control via the autocommit attribute `_, + the most straightforward approach is to set the attribute to its recommended value + of ``False`` at the connect level using :paramref:`_sa.create_engine.connect_args``:: + + from sqlalchemy import create_engine + + engine = create_engine( + "sqlite:///myfile.db", connect_args={"autocommit": False} + ) + + This parameter is also passed through when using the aiosqlite driver:: + + from sqlalchemy.ext.asyncio import create_async_engine + + engine = create_async_engine( + "sqlite+aiosqlite:///myfile.db", connect_args={"autocommit": False} + ) + + The parameter can also be set at the attribute level using the :meth:`.PoolEvents.connect` + event hook, however this will only work for sqlite3, as aiosqlite does not yet expose this + attribute on its ``Connection`` object:: + + from sqlalchemy import create_engine, event + + engine = create_engine("sqlite:///myfile.db") + + + @event.listens_for(engine, "connect") + def do_connect(dbapi_connection, connection_record): + # enable autocommit=False mode + dbapi_connection.autocommit = False + +* **Using SQLAlchemy to emit BEGIN in lieu of SQLite's transaction control** (all Python versions, sqlite3 and aiosqlite) + + For older versions of ``sqlite3`` or for cross-compatiblity with older and + newer versions, SQLAlchemy can also take over the job of transaction control. + This is achieved by using the :meth:`.ConnectionEvents.begin` hook + to emit the "BEGIN" command directly, while also disabling SQLite's control + of this command using the :meth:`.PoolEvents.connect` event hook to set the + ``Connection.isolation_level`` attribute to ``None``:: + + + from sqlalchemy import create_engine, event + + engine = create_engine("sqlite:///myfile.db") + + + @event.listens_for(engine, "connect") + def do_connect(dbapi_connection, connection_record): + # disable sqlite3's emitting of the BEGIN statement entirely. + dbapi_connection.isolation_level = None + + + @event.listens_for(engine, "begin") + def do_begin(conn): + # emit our own BEGIN. sqlite3 still emits COMMIT/ROLLBACK correctly + conn.exec_driver_sql("BEGIN") + + When using the asyncio variant ``aiosqlite``, refer to ``engine.sync_engine`` + as in the example below:: + + from sqlalchemy import create_engine, event + from sqlalchemy.ext.asyncio import create_async_engine + + engine = create_async_engine("sqlite+aiosqlite:///myfile.db") + + + @event.listens_for(engine.sync_engine, "connect") + def do_connect(dbapi_connection, connection_record): + # disable aiosqlite's emitting of the BEGIN statement entirely. + dbapi_connection.isolation_level = None + + + @event.listens_for(engine.sync_engine, "begin") + def do_begin(conn): + # emit our own BEGIN. aiosqlite still emits COMMIT/ROLLBACK correctly + conn.exec_driver_sql("BEGIN") + +.. _sqlite_isolation_level: + +Using SQLAlchemy's Driver Level AUTOCOMMIT Feature with SQLite +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +SQLAlchemy has a comprehensive database isolation feature with optional +autocommit support that is introduced in the section :ref:`dbapi_autocommit`. + +For the ``sqlite3`` and ``aiosqlite`` drivers, SQLAlchemy only includes +built-in support for "AUTOCOMMIT".

The Python sqlite3 driver supports this mode under modern Python +3 versions. The SQLAlchemy pysqlite driver supports this mode of use by +specifying "uri=true" in the URL query string. The SQLite-level "URI" is kept +as the "database" portion of the SQLAlchemy url (that is, following a slash):: + + e = create_engine("sqlite:///file:path/to/database?mode=ro&uri=true") + +.. note:: The "uri=true" parameter must appear in the **query string** + of the URL. It will not currently work as expected if it is only + present in the :paramref:`_sa.create_engine.connect_args` + parameter dictionary. + +The logic reconciles the simultaneous presence of SQLAlchemy's query string and +SQLite's query string by separating out the parameters that belong to the +Python sqlite3 driver vs. those that belong to the SQLite URI. This is +achieved through the use of a fixed list of parameters known to be accepted by +the Python side of the driver. For example, to include a URL that indicates +the Python sqlite3 "timeout" and "check_same_thread" parameters, along with the +SQLite "mode" and "nolock" parameters, they can all be passed together on the +query string:: + + e = create_engine( + "sqlite:///file:path/to/database?" + "check_same_thread=true&timeout=10&mode=ro&nolock=1&uri=true" + ) + +Above, the pysqlite / sqlite3 DBAPI would be passed arguments as:: + + sqlite3.connect( + "file:path/to/database?mode=ro&nolock=1", + check_same_thread=True, + timeout=10, + uri=True, + ) + +Regarding future parameters added to either the Python or native drivers. new +parameter names added to the SQLite URI scheme should be automatically +accommodated by this scheme. New parameter names added to the Python driver +side can be accommodated by specifying them in the +:paramref:`_sa.create_engine.connect_args` dictionary, +until dialect support is +added by SQLAlchemy. For the less likely case that the native SQLite driver +adds a new parameter name that overlaps with one of the existing, known Python +driver parameters (such as "timeout" perhaps), SQLAlchemy's dialect would +require adjustment for the URL scheme to continue to support this. + +As is always the case for all SQLAlchemy dialects, the entire "URL" process +can be bypassed in :func:`_sa.create_engine` through the use of the +:paramref:`_sa.create_engine.creator` +parameter which allows for a custom callable +that creates a Python sqlite3 driver level connection directly. + +.. versionadded:: 1.3.9 + +.. seealso:: + + `Uniform Resource Identifiers `_ - in + the SQLite documentation + +.. _pysqlite_regexp: + +Regular Expression Support +--------------------------- + +.. versionadded:: 1.4 + +Support for the :meth:`_sql.ColumnOperators.regexp_match` operator is provided +using Python's re.search_ function. SQLite itself does not include a working +regular expression operator; instead, it includes a non-implemented placeholder +operator ``REGEXP`` that calls a user-defined function that must be provided. + +SQLAlchemy's implementation makes use of the pysqlite create_function_ hook +as follows:: + + + def regexp(a, b): + return re.search(a, b) is not None + + + sqlite_connection.create_function( + "regexp", + 2, + regexp, + ) + +There is currently no support for regular expression flags as a separate +argument, as these are not supported by SQLite's REGEXP operator, however these +may be included inline within the regular expression string. See `Python regular expressions`_ for +details. + +.. seealso:: + + `Python regular expressions`_: Documentation for Python's regular expression syntax. + +.. _create_function: https://docs.python.org/3/library/sqlite3.html#sqlite3.Connection.create_function + +.. _re.search: https://docs.python.org/3/library/re.html#re.search + +.. _Python regular expressions: https://docs.python.org/3/library/re.html#re.search + + + +Compatibility with sqlite3 "native" date and datetime types +----------------------------------------------------------- + +The pysqlite driver includes the sqlite3.PARSE_DECLTYPES and +sqlite3.PARSE_COLNAMES options, which have the effect of any column +or expression explicitly cast as "date" or "timestamp" will be converted +to a Python date or datetime object. The date and datetime types provided +with the pysqlite dialect are not currently compatible with these options, +since they render the ISO date/datetime including microseconds, which +pysqlite's driver does not. Additionally, SQLAlchemy does not at +this time automatically render the "cast" syntax required for the +freestanding functions "current_timestamp" and "current_date" to return +datetime/date types natively. Unfortunately, pysqlite +does not provide the standard DBAPI types in ``cursor.description``, +leaving SQLAlchemy with no way to detect these types on the fly +without expensive per-row type checks. + +Keeping in mind that pysqlite's parsing option is not recommended, +nor should be necessary, for use with SQLAlchemy, usage of PARSE_DECLTYPES +can be forced if one configures "native_datetime=True" on create_engine():: + + engine = create_engine( + "sqlite://", + connect_args={ + "detect_types": sqlite3.PARSE_DECLTYPES | sqlite3.PARSE_COLNAMES + }, + native_datetime=True, + ) + +With this flag enabled, the DATE and TIMESTAMP types (but note - not the +DATETIME or TIME types...confused yet ?) will not perform any bind parameter +or result processing. Execution of "func.current_date()" will return a string. +"func.current_timestamp()" is registered as returning a DATETIME type in +SQLAlchemy, so this function still receives SQLAlchemy-level result +processing. + +.. _pysqlite_threading_pooling: + +Threading/Pooling Behavior +--------------------------- + +The ``sqlite3`` DBAPI by default prohibits the use of a particular connection +in a thread which is not the one in which it was created. As SQLite has +matured, it's behavior under multiple threads has improved, and even includes +options for memory only databases to be used in multiple threads. + +The thread prohibition is known as "check same thread" and may be controlled +using the ``sqlite3`` parameter ``check_same_thread``, which will disable or +enable this check. SQLAlchemy's default behavior here is to set +``check_same_thread`` to ``False`` automatically whenever a file-based database +is in use, to establish compatibility with the default pool class +:class:`.QueuePool`. + +The SQLAlchemy ``pysqlite`` DBAPI establishes the connection pool differently +based on the kind of SQLite database that's requested: + +* When a ``:memory:`` SQLite database is specified, the dialect by default + will use :class:`.SingletonThreadPool`. This pool maintains a single + connection per thread, so that all access to the engine within the current + thread use the same ``:memory:`` database - other threads would access a + different ``:memory:`` database. The ``check_same_thread`` parameter + defaults to ``True``. +* When a file-based database is specified, the dialect will use + :class:`.QueuePool` as the source of connections. at the same time, + the ``check_same_thread`` flag is set to False by default unless overridden. + + .. versionchanged:: 2.0 + + SQLite file database engines now use :class:`.QueuePool` by default. + Previously, :class:`.NullPool` were used. The :class:`.NullPool` class + may be used by specifying it via the + :paramref:`_sa.create_engine.poolclass` parameter. + +Disabling Connection Pooling for File Databases +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Pooling may be disabled for a file based database by specifying the +:class:`.NullPool` implementation for the :func:`_sa.create_engine.poolclass` +parameter:: + + from sqlalchemy import NullPool + + engine = create_engine("sqlite:///myfile.db", poolclass=NullPool) + +It's been observed that the :class:`.NullPool` implementation incurs an +extremely small performance overhead for repeated checkouts due to the lack of +connection reuse implemented by :class:`.QueuePool`. However, it still +may be beneficial to use this class if the application is experiencing +issues with files being locked. + +Using a Memory Database in Multiple Threads +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +To use a ``:memory:`` database in a multithreaded scenario, the same +connection object must be shared among threads, since the database exists +only within the scope of that connection. The +:class:`.StaticPool` implementation will maintain a single connection +globally, and the ``check_same_thread`` flag can be passed to Pysqlite +as ``False``:: + + from sqlalchemy.pool import StaticPool + + engine = create_engine( + "sqlite://", + connect_args={"check_same_thread": False}, + poolclass=StaticPool, + ) + +Note that using a ``:memory:`` database in multiple threads requires a recent +version of SQLite. + +Using Temporary Tables with SQLite +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Due to the way SQLite deals with temporary tables, if you wish to use a +temporary table in a file-based SQLite database across multiple checkouts +from the connection pool, such as when using an ORM :class:`.Session` where +the temporary table should continue to remain after :meth:`.Session.commit` or +:meth:`.Session.rollback` is called, a pool which maintains a single +connection must be used. Use :class:`.SingletonThreadPool` if the scope is +only needed within the current thread, or :class:`.StaticPool` is scope is +needed within multiple threads for this case:: + + # maintain the same connection per thread + from sqlalchemy.pool import SingletonThreadPool + + engine = create_engine("sqlite:///mydb.db", poolclass=SingletonThreadPool) + + + # maintain the same connection across all threads + from sqlalchemy.pool import StaticPool + + engine = create_engine("sqlite:///mydb.db", poolclass=StaticPool) + +Note that :class:`.SingletonThreadPool` should be configured for the number +of threads that are to be used; beyond that number, connections will be +closed out in a non deterministic way. + + +Dealing with Mixed String / Binary Columns +------------------------------------------------------ + +The SQLite database is weakly typed, and as such it is possible when using +binary values, which in Python are represented as ``b'some string'``, that a +particular SQLite database can have data values within different rows where +some of them will be returned as a ``b''`` value by the Pysqlite driver, and +others will be returned as Python strings, e.g. ``''`` values. This situation +is not known to occur if the SQLAlchemy :class:`.LargeBinary` datatype is used +consistently, however if a particular SQLite database has data that was +inserted using the Pysqlite driver directly, or when using the SQLAlchemy +:class:`.String` type which was later changed to :class:`.LargeBinary`, the +table will not be consistently readable because SQLAlchemy's +:class:`.LargeBinary` datatype does not handle strings so it has no way of +"encoding" a value that is in string format. + +To deal with a SQLite table that has mixed string / binary data in the +same column, use a custom type that will check each row individually:: + + from sqlalchemy import String + from sqlalchemy import TypeDecorator + + + class MixedBinary(TypeDecorator): + impl = String + cache_ok = True + + def process_result_value(self, value, dialect): + if isinstance(value, str): + value = bytes(value, "utf-8") + elif value is not None: + value = bytes(value) + + return value + +Then use the above ``MixedBinary`` datatype in the place where +:class:`.LargeBinary` would normally be used. + +.. _pysqlite_serializable: + +Serializable isolation / Savepoints / Transactional DDL +------------------------------------------------------- + +A newly revised version of this important section is now available +at the top level of the SQLAlchemy SQLite documentation, in the section +:ref:`sqlite_transactions`. + + +.. _pysqlite_udfs: + +User-Defined Functions +---------------------- + +pysqlite supports a `create_function() `_ +method that allows us to create our own user-defined functions (UDFs) in Python and use them directly in SQLite queries. +These functions are registered with a specific DBAPI Connection. + +SQLAlchemy uses connection pooling with file-based SQLite databases, so we need to ensure that the UDF is attached to the +connection when it is created. That is accomplished with an event listener:: + + from sqlalchemy import create_engine + from sqlalchemy import event + from sqlalchemy import text + + + def udf(): + return "udf-ok" + + + engine = create_engine("sqlite:///./db_file") + + + @event.listens_for(engine, "connect") + def connect(conn, rec): + conn.create_function("udf", 0, udf) + + + for i in range(5): + with engine.connect() as conn: + print(conn.scalar(text("SELECT UDF()"))) + +""" #

Does not affect :class:`.Column` objects that + are mapped explicitly in the :paramref:`.Mapper.properties` + dictionary. + + This parameter is typically useful with imperative mappings + that keep the :class:`.Table` object separate.

For dealing with reflected tables, a more flexible + approach to automating a naming scheme is to intercept the + :class:`.Column` objects as they are reflected; see the section + :ref:`mapper_automated_reflection_schemes` for notes on this usage + pattern. + + :param concrete: If True, indicates this mapper should use concrete + table inheritance with its parent mapper. + + See the section :ref:`concrete_inheritance` for an example. + + :param confirm_deleted_rows: defaults to True; when a DELETE occurs + of one more rows based on specific primary keys, a warning is + emitted when the number of rows matched does not equal the number + of rows expected. This parameter may be set to False to handle the + case where database ON DELETE CASCADE rules may be deleting some of + those rows automatically. The warning may be changed to an + exception in a future release. + + :param eager_defaults: if True, the ORM will immediately fetch the + value of server-generated default values after an INSERT or UPDATE, + rather than leaving them as expired to be fetched on next access. + This can be used for event schemes where the server-generated values + are needed immediately before the flush completes. + + The fetch of values occurs either by using ``RETURNING`` inline + with the ``INSERT`` or ``UPDATE`` statement, or by adding an + additional ``SELECT`` statement subsequent to the ``INSERT`` or + ``UPDATE``, if the backend does not support ``RETURNING``. + + The use of ``RETURNING`` is extremely performant in particular for + ``INSERT`` statements where SQLAlchemy can take advantage of + :ref:`insertmanyvalues `, whereas the use of + an additional ``SELECT`` is relatively poor performing, adding + additional SQL round trips which would be unnecessary if these new + attributes are not to be accessed in any case. + + For this reason, :paramref:`.Mapper.eager_defaults` defaults to the + string value ``"auto"``, which indicates that server defaults for + INSERT should be fetched using ``RETURNING`` if the backing database + supports it and if the dialect in use supports "insertmanyreturning" + for an INSERT statement.

In most cases can be left as ``None``. + + :param legacy_is_orphan: Boolean, defaults to ``False``. + When ``True``, specifies that "legacy" orphan consideration + is to be applied to objects mapped by this mapper, which means + that a pending (that is, not persistent) object is auto-expunged + from an owning :class:`.Session` only when it is de-associated + from *all* parents that specify a ``delete-orphan`` cascade towards + this mapper. The new default behavior is that the object is + auto-expunged when it is de-associated with *any* of its parents + that specify ``delete-orphan`` cascade.

If the primary key attributes local to this + table are unloaded, then a SELECT must be emitted in order to + validate these attributes; note that the primary key columns + of a joined-table subclass are not part of the "primary key" of + the object as a whole. + + Note that a value of ``True`` is **always** forced onto the + subclass mappers; that is, it's not possible for a superclass + to specify passive_deletes without this taking effect for + all subclass mappers. + + .. seealso:: + + :ref:`passive_deletes` - description of similar feature as + used with :func:`_orm.relationship` + + :paramref:`.mapper.passive_updates` - supporting ON UPDATE + CASCADE for joined-table inheritance mappers + + :param passive_updates: Indicates UPDATE behavior of foreign key + columns when a primary key column changes on a joined-table + inheritance mapping. Defaults to ``True``. + + When True, it is assumed that ON UPDATE CASCADE is configured on + the foreign key in the database, and that the database will handle + propagation of an UPDATE from a source column to dependent columns + on joined-table rows. + + When False, it is assumed that the database does not enforce + referential integrity and will not be issuing its own CASCADE + operation for an update. The unit of work process will + emit an UPDATE statement for the dependent columns during a + primary key change. + + .. seealso:: + + :ref:`passive_updates` - description of a similar feature as + used with :func:`_orm.relationship` + + :paramref:`.mapper.passive_deletes` - supporting ON DELETE + CASCADE for joined-table inheritance mappers + + :param polymorphic_load: Specifies "polymorphic loading" behavior + for a subclass in an inheritance hierarchy (joined and single + table inheritance only). Valid values are: + + * "'inline'" - specifies this class should be part of + the "with_polymorphic" mappers, e.g. its columns will be included + in a SELECT query against the base. + + * "'selectin'" - specifies that when instances of this class + are loaded, an additional SELECT will be emitted to retrieve + the columns specific to this subclass. The SELECT uses + IN to fetch multiple subclasses at once. + + .. versionadded:: 1.2 + + .. seealso:: + + :ref:`with_polymorphic_mapper_config` + + :ref:`polymorphic_selectin` + + :param polymorphic_on: Specifies the column, attribute, or + SQL expression used to determine the target class for an + incoming row, when inheriting classes are present. + + May be specified as a string attribute name, or as a SQL + expression such as a :class:`_schema.Column` or in a Declarative + mapping a :func:`_orm.mapped_column` object. It is typically + expected that the SQL expression corresponds to a column in the + base-most mapped :class:`.Table`:: + + class Employee(Base): + __tablename__ = "employee" + + id: Mapped[int] = mapped_column(primary_key=True) + discriminator: Mapped[str] = mapped_column(String(50)) + + __mapper_args__ = { + "polymorphic_on": discriminator, + "polymorphic_identity": "employee", + } + + It may also be specified + as a SQL expression, as in this example where we + use the :func:`.case` construct to provide a conditional + approach:: + + class Employee(Base): + __tablename__ = "employee" + + id: Mapped[int] = mapped_column(primary_key=True) + discriminator: Mapped[str] = mapped_column(String(50)) + + __mapper_args__ = { + "polymorphic_on": case( + (discriminator == "EN", "engineer"), + (discriminator == "MA", "manager"), + else_="employee", + ), + "polymorphic_identity": "employee", + } + + It may also refer to any attribute using its string name, + which is of particular use when using annotated column + configurations:: + + class Employee(Base): + __tablename__ = "employee" + + id: Mapped[int] = mapped_column(primary_key=True) + discriminator: Mapped[str] + + __mapper_args__ = { + "polymorphic_on": "discriminator", + "polymorphic_identity": "employee", + } + + When setting ``polymorphic_on`` to reference an + attribute or expression that's not present in the + locally mapped :class:`_schema.Table`, yet the value + of the discriminator should be persisted to the database, + the value of the + discriminator is not automatically set on new + instances; this must be handled by the user, + either through manual means or via event listeners. + A typical approach to establishing such a listener + looks like:: + + from sqlalchemy import event + from sqlalchemy.orm import object_mapper + + + @event.listens_for(Employee, "init", propagate=True) + def set_identity(instance, *arg, **kw): + mapper = object_mapper(instance) + instance.discriminator = mapper.polymorphic_identity + + Where above, we assign the value of ``polymorphic_identity`` + for the mapped class to the ``discriminator`` attribute, + thus persisting the value to the ``discriminator`` column + in the database. + + .. warning:: + + Currently, **only one discriminator column may be set**, typically + on the base-most class in the hierarchy. "Cascading" polymorphic + columns are not yet supported. + + .. seealso:: + + :ref:`inheritance_toplevel` + + :param polymorphic_identity: Specifies the value which + identifies this particular class as returned by the column expression + referred to by the :paramref:`_orm.Mapper.polymorphic_on` setting. As + rows are received, the value corresponding to the + :paramref:`_orm.Mapper.polymorphic_on` column expression is compared + to this value, indicating which subclass should be used for the newly + reconstructed object. + + .. seealso:: + + :ref:`inheritance_toplevel` + + :param properties: A dictionary mapping the string names of object + attributes to :class:`.MapperProperty` instances, which define the + persistence behavior of that attribute. Note that + :class:`_schema.Column` + objects present in + the mapped :class:`_schema.Table` are automatically placed into + ``ColumnProperty`` instances upon mapping, unless overridden. + When using Declarative, this argument is passed automatically, + based on all those :class:`.MapperProperty` instances declared + in the declared class body. + + .. seealso:: + + :ref:`orm_mapping_properties` - in the + :ref:`orm_mapping_classes_toplevel` + + :param primary_key: A list of :class:`_schema.Column` + objects, or alternatively string names of attribute names which + refer to :class:`_schema.Column`, which define + the primary key to be used against this mapper's selectable unit. + This is normally simply the primary key of the ``local_table``, but + can be overridden here. + + .. versionchanged:: 2.0.2 :paramref:`_orm.Mapper.primary_key` + arguments may be indicated as string attribute names as well. + + .. seealso:: + + :ref:`mapper_primary_key` - background and example use + + :param version_id_col: A :class:`_schema.Column` + that will be used to keep a running version id of rows + in the table. This is used to detect concurrent updates or + the presence of stale data in a flush. The methodology is to + detect if an UPDATE statement does not match the last known + version id, a + :class:`~sqlalchemy.orm.exc.StaleDataError` exception is + thrown. + By default, the column must be of :class:`.Integer` type, + unless ``version_id_generator`` specifies an alternative version + generator. + + .. seealso:: + + :ref:`mapper_version_counter` - discussion of version counting + and rationale. + + :param version_id_generator: Define how new version ids should + be generated.

Its behavior is fairly idiosyncratic + and is not really intended for general use. End users should + stick with using :meth:`.UpdateBase.returning` in order to + add RETURNING clauses to their INSERT, UPDATE and DELETE + statements. + + Normally, a single row INSERT statement will automatically populate the + :attr:`.CursorResult.inserted_primary_key` attribute when executed, + which stores the primary key of the row that was just inserted in the + form of a :class:`.Row` object with column names as named tuple keys + (and the :attr:`.Row._mapping` view fully populated as well). The + dialect in use chooses the strategy to use in order to populate this + data; if it was generated using server-side defaults and / or SQL + expressions, dialect-specific approaches such as ``cursor.lastrowid`` + or ``RETURNING`` are typically used to acquire the new primary key + value. + + However, when the statement is modified by calling + :meth:`.UpdateBase.return_defaults` before executing the statement, + additional behaviors take place **only** for backends that support + RETURNING and for :class:`.Table` objects that maintain the + :paramref:`.Table.implicit_returning` parameter at its default value of + ``True``.

The RETURNING clause of the INSERT, UPDATE or + DELETE statement is therefore controlled by only one of these methods + at a time. + + The :meth:`.UpdateBase.return_defaults` method differs from + :meth:`.UpdateBase.returning` in these ways: + + 1. :meth:`.UpdateBase.return_defaults` method causes the + :attr:`.CursorResult.returned_defaults` collection to be populated + with the first row from the RETURNING result.
