Hi

A class named "B" inherit from a "A" class, i use the table per subclass strategy, so i have two table "A" and "B". "B" have a field "IdB" which is FK and PK to the "A" class.

How can i convert an instance of A in B? In sql is very simple, i add a new row in the "B" table and all is ok.....but in Nhibernate and my domain model?

Thank in advance
Giorgio

You don't do the conversion.
Types doesn't change in NHibernate.
You will probably do this using SQL command and then loading the object, though

Thank for yoru reply.... i will use a storeprocedure + trigger
