You are probably right. But for me it is simple necessary to delete all child rows when the parent table is deleted. But it does not matter if the child table entries match the parent table. The program maintains the the referential integrity on its own; except there is one entry in the child table that will not be in the parent table. This is why I can't go with a constraint.
