I want to write a trigger that updates a different row on the same
table. It's pretty basic: before the any row in his table updated I
want to set a only row that has the value true to false. I keep getting
this error:
SQL statement "update theirry.articles set master_featured = false where
master_featured = true"
PL/pgSQL function "master_featured_maintenance" line 4 at SQL statement
My basic trigger:
CREATE OR REPLACE FUNCTION theirry.master_featured_maintenance()
RETURNS TRIGGER AS
$master_featured_maintenance$ DECLARE master_feature boolean; BEGIN update theirry.articles
set master_featured = false where master_featured = true; END;
$master_featured_maintenance$
LANGUAGE plpgsql;
CREATE TRIGGER master_featured_maintenance
BEFORE INSERT OR UPDATE ON theirry.articles FOR EACH ROW EXECUTE PROCEDURE theirry.master_featured_maintenance();
Thanks in advance,
J
