[SQL] Possible to emulate pre-8.2 behaviour of SET CONSTRAINTS?

s, or some other technique? I'm relunctant to use SET CONSTRAINTS' 'ALL' clause in case it messes with other constraints in the system. Hope this makes sense, Simon --- Simon Kinsella Technical Director - Bluefire Systems Ltd This message has been scanned for viruses. --

[SQL] Help with distinctly non-intuitive rule behaviour

n-key violation resulting from an unmolested DELETE action even for a user who has not been soft-deleted. If as a test I change the UPDATE action so that it does something other than change the timestamp then the rule is applied. This seems pretty weird - can it be true? --- Simon
