Hi all. I've come across a problem with delete cascade. I have three tables A, B and C. Table B has a foreign key on A with delete cascade. Table C has a foreign key on B with delete cascade. So, we have this reference chain: C->B->A All three tables have an 'on delete' trigger. My problem is, when I delete a row from A, the delete triggers are fired in the order A then B then C, which is the opposite of what I expected (the row from B should be deleted before the A one, or the reference constraint would break).
The "on delete cascade" are (sort of) implemented with system triggers. So deleting a row from A triggers a delete on B where fkey=X and so on.
This happens with 'after' and 'before' triggers. I really need the order to be C then B then A.
