Hibernate version: 3.2

Hello,

I got a legacy database with uses Varchar2 Columns for FKs. The application using the database uses the string "-" for not existing references in one-to-one relationships instead of null.

Currently I have no idea, how to define a mapping, so that I can interpret the minus character as a null reference, accept overloading half of the hibernate type system.

Does any one faced such a problem before? How did you solved it?

I appreciate any answer.

Best Regards
