Hi 2 all!
I have such hibernate mapping:

if anyone knows how to delete records from TABLE2 without deleting corresponding records in TABLE1?

Unless Class1 is abstract, I see no serious obstacle to deletion from Table2 by raw SQL or by a separately mapped class; this appears easier than trying to change the type of an entity object from Class2 to Class1.
I hope that you have a reason for changing the type, but that's another question...
