small webpage is grabbing some contactdata.
i have a shell script which drops and recreates datatbase
and the cat the following with
cat sql_commands | psql kontaktdaten
last thing i added was the telephone check
and it seems that the backend just dont care about it.
but i do believe that i did a mistake anywhere else, os i go and search for
it.
>>> file sql_commands
\connect - janning
CREATE TABLE kontakte (
kontakte_id serial,
empfaenger text,
anrede text,
name text,
vorname text,
email text,
telefon text,
firma text,
nachricht text,
aufmerksam text,
newsletter text
);
CREATE FUNCTION check_kontakte () RETURNS OPAQUE AS '
BEGIN
IF NEW.anrede = ''0'' THEN
NEW.anrede := NULL;
END IF;
IF NEW.aufmerksam = ''0'' THEN
NEW.aufmerksam := NULL;
END IF;
IF NEW.telefon ISNULL THEN
RAISE EXCEPTION ''Bitte geben Sie ihre Telefonnumer an'';
RETURN NULL;
END IF;
RETURN NEW;
END;
' LANGUAGE 'plpgsql';
CREATE TRIGGER if_kontakte BEFORE INSERT OR UPDATE ON kontakte
FOR EACH ROW EXECUTE PROCEDURE check_kontakte();
