Hibernate version:2.1.6

I have a table per hierarchy mapping.

In the "Parent" table, I have a <disciminator> column called "type", which hibernate happily reads and constructs the various derrived objects. This all works fine.

Im trying to write queries to return me a subset of the parent data, switching on these type codes.

Is this possible? If so, how?

Hibernate wants to run the query against a mapped property, but the <disciminator> isnt a property.
