The following code is not meaningfull but it's an extract of what I'm trying to do: CREATE TABLE foo ( field1 INTEGER ); CREATE OR REPLACE FUNCTION trigger_foo() RETURNS TRIGGER AS' DECLARE ~ my_field TEXT; ~ my_stat TEXT; BEGIN ~ my_field = TG_ARGV[0]; ~ my_stat = ''SELECT field1 FROM foo where field1 = NEW.'' || my_field; ~ EXECUTE my_stat; ~ RETURN NEW; END; ' LANGUAGE 'plpgsql'; CREATE TRIGGER check_foo BEFORE INSERT ON foo FOR EACH ROW EXECUTE PROCEDURE trigger_foo('field1'); insert into foo values ( 3 ); I got the error in the subject, it's like the EXECUTE open another contest and forget that is inside a rule. Any idea someone ?
