Howdy, I'm trying to think of the best way to handle this situation.
I've got 2 tables, X and Y Table X has a field foo varchar(20) Table Y has a field bar varchar(20) I want to enforce, that if table X.foo = 'dave' then you can't insert (or update) Y.bar = 'dave' I know this is ideally done in the app, but in the interest of time to market i'm looking into a simple DB solution. I know i can do this with a trigger, but was wondering if there was a better way, like using a constraint or a rule (seems like that would be pretty slick - but i can't wrap my head around how to make it work) Thanks Dave -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
