Guys, Please see the question again. It is related to
deleting different tables. I guess, the question is
intented to get the answer - ON DELETE CASCADE. We give
foreign constraints on tables and when the parent record is
deleted, the child records are automatically deleted when
you give command as ON DELETE CASCADE
