Can't you just specify a Where clause in the definition of the single class mapping.

If I only want to get a specific type of address from the database and I don't have a subclass, NHibernate wouldn't return the correct result. It would return all rows, instead of just the rows with the specific address_type_code. I just looked at the release notes for NH 2.0 and it looks like this scenario is supported. Added [ Table per subclass, using a discriminator ] Support to Nhibernate http://ayende.com/Blog/archive/2008/03/31/NHibernate-2.0-Alpha-is-out.as px unfortunately, I can't upgrade to NH 2.0. I understand NH might not consider this a valid use case, but I definitely consider it a valid use case. peter On Sep 26, 11:20 am, "Fabio Maulo" <[EMAIL PROTECTED]> wrote: > Why you think that it is a bug ?If a class don't have a <subclass> (mean you > have only one value for discriminator and that mean don't have nothing to > discriminate), why NH must add the discriminator clause ? > > 2008/9/26 Peter Lin <[EMAIL PROTECTED]> > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "nhusers" group.
