NHibernate - How to store UInt32 in database

Question

What is the best way to map UInt32 type to sql-server int type with NHibernate.

The value is a picture width/height so negative value are not make sense here.

I'm a year late, but since I had the same question and found a different answer I thought I'd add it. It seems simpler. Maybe it has a flaw I haven't discovered yet.

I'm using NHibernate 3.0, Visual Studio 2005, and .NET 2.0.x.

I found I could use .NET's UInt32 class and not include the type attribute in the hbm.xml.

// .NET 2.0 Property syntax
public class MyClass
{
   // NHibernate needs public virtual properties. 
   private UInt32 _Id;
   public virtual UInt32 Id { get { return (_Id); } set { _Id = value; } }
}


// hbml.xml

   



// SQL to create the table
CREATE TABLE `PumpConnection` (
`Id` **INT**(10) **UNSIGNED** NOT NULL AUTO_INCREMENT,
)
