James,

It would help to provide the definitions of the entities.  It all depends on how you setup the restricting qualifiers and primary keys.  Do all 3 have the same associated table?

OK -

When I just the SQL...

It actually does three selects and not one.
It does a select for each of the children entities and then for the parent class.

Why? I am just asking or fetching the parentClass. Why does it want to also search by Qualifier of the subclasses?

Thanks
James
