Sorry for the last post, finger error.
Anyways, I find all types of example like this:
CREATE FUNCTION somefunc() RETURNS INTEGER AS
I'm looking for an example of a function that will prevent an insert
based on a pattern match. Is this possible and if so DO I need to return
something? I guess to sum to it up, I need a function that will match a
pattern and then a trigger that will not allow an insert based on what
that function matches.
I'm sure I am just making this harder than it really is...
