How do you "OR" criteria together when using a criteria query with hibernate? |
|java|hibernate| |
I'm trying to do a basic "OR" on three fields using a hibernate criteria query.
Example
class{
string name;
string address;
string phoneNumber;
}
I'd like to build a criteria query where my search string could match "name" or "address" or "phoneNumber".

.NET 1.1 and .NET 2.0-3.5 are entirely different frameworks, and more importantly, .NET 3.5 is just a set of extra assemblies you can add to your .NET 2.0 project - none of the core assemblies actually got changed, as far as I'm aware - and an upgraded compiler that knows about the syntax sugar called LINQ, extension m... |
Another benefit, is that a reference can never be NULL. No more exhaustive parameter checking :-). |
Class views in Django |
|python|django|view|oop| |
[Django][1] view points to a function, which can be a problem if you want to change only a bit of functionality. Yes, I could have million keyword arguments and even more if statements in the function, but I was thinking more of an object oriented approach.
For example, I have a page that displays a user. This page ... |

Here's part of my `.vimrc`:

It's not a matter of finding a leak. In case of smart-pointers it'll most probably direct to some generic place like CreateObject(), which is being called thousands of time. It's a matter of determining what place in the code didnt call Release() on ref-counted object. |

*this* is used in the assignment operator where most of the time you have to check and prevent strange (unintentional, dangerous, or just a waste of time for the program) things like:
A a;
a = a;
Your assignment operator will be written:

No, it will not. Currently, ASP.NET MVC doesn't have an inherent validation framework. So you are free to use any server/client-side validation framework you wish. |

I would familiarize myself with the problem first by reading up on some of the literature that's available on the subject.

Short of authoring your own controls, I'm afraid that the route you don't want to go (making a second, label-only page) is probably a pretty good route simply because you don't want someone running Firebug who can edit HTML on the fly to just turn off whatever control you have in place and just use the page as if they ... |

I had this same problem a few years ago and it irked me to no end.
The rules in C are more simply stated (i.e. they don't list exceptions like converting char** to const char*const*). Consequenlty, it's just not allowed. With the C++ standard, they included more rules to allow cases like this.

Yes - Unit Testing is definitely worth the effort but you should know it's not a silver bullet.

Copying rows to a table throws some flags at me. I've seen people try this before, and in every single case what they really wanted was a [System.Data.DataView][1]. You really should check to see if the [RowFilter][2] property will do what you need it to do.

No, CodeWarrior uses a different object file format than PRC-Tools. Also, the compiler support libraries are different, so even if the code could be statically linked together, it may use symbols in a different way.

If you mean

then it is impossible. And I would add that it is not always correct - how do you know if E has public no-args constructor?

An alternative method favours speed when selecting the broker over memory usage. Basically we create the list containing the same number of references to a broker instance as the specified weight.

The naive approach is to build a tree with the source node as the root and all its connections as its children. Depending on the amount of space you have, you might need to eliminate cycles as you go. You can do that with a bitmap where each bit corresponds to a distinct node in the graph. When you reach the target nod... |
UDT capability is only listed in 11g clients and the latest 64 bit client is 10.2.0.3.

You can have an "extension" on your folder, but as far as I know, windows just treats it all as the folder name and opens the folder like normal when you click on it.

It might be best not to wrap everything in an anonymous function and just hope that it is executed. You could name the function, and put its name in the body tag's onload handler. This should ensure that it's run each time the page is loaded. |
