DetachedCriteria.forClass also loads the subclass as well

Hi All,

I have two classes A and B, with class B is the sub class of class A. These two classes are mapped to two tables (table TA and TB) independently.

Right now looks like if I want to do a query to get just the records in table TA which Class A maps against. When I use the following
DetachedCriteria.forClass(A.class)

The returned result sets include both instances of Class A as well as Class B. Also I can see there are two sql queries have been issued by Hibernate to database with one sql queries table TA and another one for table TB.

Is there a way I can let Hibernate know that only the specified class( not its subclasses) need to be returned?

Thanks a lot for any idea you might have on this.

-Harriet

Please note the workaround mentioned, i.e. using the discriminator directly.
