as of now i haven't mentioned any inverse attribute.But hiberante only updating child foreign keys.Due to this it was generating many update statements while updating time.I want to reduce those calls by using inverse=true.I have tested like that also but child table was not updating with parent key.What might be the problem.
Please anybody help me!
Best Regards,
Murali.
