Thanks people, but the trigger doesnt really solve my problem. You see, there is actually a CHAIN of dependencies where B references A, C references B, D and E reference C and so on... So if i start writing triggers for all these, there'll be a huge process to follow. I'm not strictly against it, i might use it as a last resort, but i'm asking if a simple DML statement would solve my problem.
Dear Shoaib, I did mention in a note that I don't want to recreate the 2 tables with the 'on delete cascade' clause. The tables are ALREADY created and populated. And they are huge. So i cannot afford to drop and recreate them. I want an option in DML only. If that is possible that is. Thanks, Shruthi
