Hi,

I'm deleting a record in parent table, inorder to delete all the records in child tables related to the parent key if i use on delete cascade will it delete all the records in child tables? Here the records are spread into different tables from one segment(ims). In ims he is deleting the record then that record will be deleted. to do the same in db2 if i mention ondelete cascade will all the records pertaining to that parent record will be deleted or not?

Thanks in advance and Wish you Happy New year.

Nadh,

Your child tables should be defined with DELETE CASCADE when they are created. This allows the rows to be deleted from the child table when the parent key is deleted

Hope this helps...

Cheers
