You're missing the specification of the foreign key, not to mention
spelling the CASCADE clause backwards. Try
ALTER TABLE A ADD FOREIGN KEY(AA) REFERENCES B(BB) ON DELETE CASCADE
Got it right in the Subject: and my many attempts, just not in the
body :-)
The column already had the foreign key, I never thought to add it
again. I was only thinking of modifying the minimum necessary.
Yeah, unfortunately there's no support for modifying constraints.
