I’m using Postgres with Golang via pgx
I’ve a trigger function something like the following:
CREATE OR REPLACE FUNCTION foo()
RETURNS TRIGGER AS
$$
BEGIN
IF (bar = 'baz') THEN
-- something
ELSE
RAISE EXCEPTION 'oops error';
END IF;
RETURN NEW;
END;
$$
LANGUAGE plpgsql;
How do I check for oops error
in Go code?
The way I’m doing it now is:
errOops := errors.New("ERROR: oops error (SQLSTATE P0001)")
err := myDBFunc()
if errors.Is(err, errOops) {
}
But I wonder if there’s a better way other than relying on the hardcoded message.

Should have read the Wiki: Error Handling in
pgx
So I can do:
or something similar.
You can find that information in appendix A of the documentation: it will be a
raise_exception
, and the SQLSTATE isP0001
.
