Are you sure shikhar that ON DELETE UPDATE is a true sentance ?

I can see clearly from the SQL Foreign key constrain syntax that.

ON DELETE ( CASCADE | NO ACTION )
ON UPDATE ( CASCADE | NO ACTION )

So how you will apply ON DELETE UPDATE ? Which isn't accordingly true wrt syntax ?

Maybe OP meant to implement an INSTEAD OF trigger for DELETE?
I'm just guessing as OP is not so clear in his requirements. :)

No Manfred he's just want to apply cascade constrain while defining foreign key. but he's asking some what question that made me in confusion couple of times.
