nhibernate fluent bool to smallint mapping

问题:

In my application I have a bool property named DisplayIndicator. In the database (DB2) it's correspondence is DISPL_IND column of type smallint. The correspondence is the following: [DisplayINdicator=True, DISPL_IND=1] and [DisplayINdicator=False, DISPL_IND=0] Is it possible to map using nhibernate fluence the bool property to smallint?

回答1:

I figured it out, after Frans's advise. I created a class that represents nhibernate user type used to map boolean type to short type:

public class BooleanAsShortType : IUserType

To the mapping, I added a CustomType property and now it looks like this:

Map(x => x.DisplayIndicator, "DSPL_IND").CustomType< BooleanAsShortType >();

回答2:

You could implement IUserType on a class and convert bool to short and back and apply it to the field where you need it.
