Isn't it *supposed* to mis UNcommitted changes from other transactions?
Well, if the "uncommited change" is a DELETE of the row that
allowed the constraint check to pass, then when this delete is
commited, your data is no longer consistent.
The DELETE should block, no?
Why ?
Foreign keys put an ON DELETE trigger on the referenced table
Foreign keys that silently, automatic DELETE records?
Did I read that correctly?
besides checking the referencing column on insert/update... If you just
implement a constraint, you only get half the functionality.
But when I define a FK *constraint*, that's all I *want*!
