I have got a plpgsql function:
CREATE FUNCTION nueva_llamada(integer, integer) RETURNS integer
as
DECLARE _operadora_id ALIAS FOR $1; _actividad_id ALIAS FOR $2; _contacto_id integer;
BEGIN
-- BEGIN;
SELECT min(id) INTO _contacto_id FROM contactos WHERE contactos.operadora_id IS NULL AND contactos.actividad_id
= _actividad_id;
UPDATE contactos SET operadora_id = _operadora_id WHERE id = _contacto_id;
-- COMMIT;
INSERT INTO llamadas (contacto_id, operadora_id, fecha) VALUES (_contacto_id, _operadora_id, now());
RETURN _contacto_id;
END
and it works right, but I need atomic execution from --BEGIN and
--COMMIT, and manual says it is not possible to have transactions in
PL/pgSQL procedures :-(
May be with LOCK TABLE?
