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
