Try this:

It’s *much* faster than passing `--unreachable`, though it doesn’t show you all the unreachable commits, only the tips of the tree.

Reduced to the essential distinction, identity matters for entities, but does not matter for value objects. For example, someone's Name is a value object.

Script everything (object creation, etc) and store those scripts in source control. How do the changes get there? It's part of the standard practice of how things are done. Need to add a table? Write a CREATE TABLE script. Update a sproc? Edit the stored procedure script.
I prefer one script per object. |

For the most part, external drives aren't a good option - unless your database is really small.
Other than some of the options others have listed, you can also use UNC/Network shares as a great 'off-box' option.

The standard method to attack this problem is to consider one block of data, hopefully at least twice the actual frequency (taking more data isn't bad, so it's good to overestimate a bit), then take the [FFT][1] and guess that the frequency corresponds to the largest number in the resulting FFT spectrum.
By the way,... |
Even with the same currency, you may have to display values with a different format (separators for instance), so I would recommend that you associate a LOCALE instead of the currency only with your values.
You can use a simple Integer to hold the LCID (locale ID).

You could do the truncate after the 'create if not exists'.
That way it will always exist... and always be empty at that point.

It is legal. We use it sometime to provide a default value which we might want to ignore.

In the above case it will construct an empty error code object if no `error_code` is passed to the function. |
If you are using .Net web controls then it is sometimes a lot easier just to use classes as .Net alters web contol div id's at run time (where they are using runat="server").

Yes, as MySQL doesn't support function-based indexes (like `ADD INDEX myIndex(LENGTH(text)))`, you'll need a new int column and define a [trigger][1] to auto-update it after inserts and updates.

It is not possible, since String is a final class in Java.
