Supporting NULL able column

[Michael W Powell]

Hello,

How do I define a custom type which supports NULL. Defined as a user domain (ULONG) basically a simple NUMERIC(), so perhaps the NHibernate.SqlTypes.SqlTypeFactory.UInt64 is an appropriate basis, but what to do with the ulong? (csharp language level).

Thank you!

Best,

Michael W. Powell

I haven’t used Nhibernate for a while, but I had a similar problem with a custom field, and to do solve it I created a custom user type (class IUserType), these links explain how to do it:
