Subject AW: [firebird-support] Re: Possible bug with CHECK constraint
Author Steffen Heil
Hi, Ann.

> The standard says that immediate constraints should be evaluated AFTER the
action, not before,
so a standard compliant system would reject your update. Firebird evaluates
constraints before the action, not after.

Is there a reason for this?
I think that decition was made for a reason, but I don't see it.
Without a reason you would not violate the standard, would you?

$18/volume I really ought to get myself a copy. And so should you, all of
you.

I agree, but where can I get it for that price???

Regards,
Steffen
