Hibernate version:
2.1

Hi All,

I have 2 tables A and B with primary keys A_id and B_id. Table B has 'not null' A_id column with foreign key constraint. A can han have many B's.

In A.java B is represented as a Set. If I deep fetch A object and delete some of the elements of set B and do
session.saveOrUpdate(A);
In this case, will the rows in table B get deleted as A_id is not null column defined in table B ?

Thanks
Ron

Yes, they will be deleted (provided that cascade attribute has appropriate value like 'all')
