Hi,
I've created a function like this :
CREATE FUNCTION tester(INT4)
RETURNS BOOL AS
'
DECLARE
r RECORD;
p ALIAS FOR $1;
BEGIN
SELECT INTO r
id_dpt
FROM dpts
WHERE id_dpt=p;
IF NOT FOUND THEN
RETURN FALSE;
ELSE
RETURN TRUE;
END IF;
END;
'
LANGUAGE 'plpgsql';
All is ok at creation.
But now , how can i use my function ? i would like a thing like :
SELECT tester(14) AS ok;
But is make a Postgresql parser error
How to do then ??
Thanks for any help or links (other than the postgresql.org website...) !
;)
Regards,
Fred
