Hi,
Is it possible to return the following (parameterized) qyery from a sql or
plpsql function, and if so, what is the syntax?
SELECT{ (SELECT COUNT(klantnummer) FROM abo_klt WHERE
abonnement = $1),
(SELECT SUM(aantal_abonnementen)FROM abo_klt WHERE
OK, to answer my own question (typo's possible, works here ;-)):
CREATE TYPE abonnementartikelheader AS (col1 int4, col2 int4);
CREATE OR REPLACE FUNCTION getabonnementartikelheader(int4)
RETURNS SETOF abonnementartikelheader AS
'
select
(SELECT COUNT(klantnummer)::int4 FROM abo_klt
