Hi,
I have a problem with transaction
handling. What I need to do is execute an INSERT command that would
not be canceled by the
RAISE EXCEPTION command in AFTER UPDATE TRIGGER. A piece of code:
BEGIN
-- some computations
bledne := (SELECT g.q_sumka('Poz.' || lps || ' - min. cena: ' || cena || ' '
|| waluta ||'; ') FROM g.m_lista WHERE idf = NEW.id);
IF EXISTS (SELECT 1 FROM g.m_lista WHERE idf = NEW.id) THEN
RAISE EXCEPTION 'CENY NIE SPELNIAJA WARUNKOW! %', rtrim(bledne);
BEGIN
INSERT INTO g.m_proba VALUES (1,2); -- this is the operation I need to
perform but the RAISE EXCEPTION above cancels it out
PREPARE TRANSACTION 'a';
COMMIT PREPARED 'a';
END;
END IF;
I tried to do it as shown above, with PREPARE and COMMIT but it's not
working.
