Hi, many thanks for this suggestion. But the problem with this is that you have to know which columns are returned when you call the function.

Is there any way to achieve something similar in PostreSQL? testing=# CREATE OR REPLACE FUNCTION public.rr(p INTEGER) RETURNS SETOF RECORD LANGUAGE plpgsql AS $function$ BEGIN IF p = 1 THEN RETURN NEXT ('k1'::TEXT, 'v1'::TEXT); RETURN NEXT ('k2'::TEXT, 'v2'::TEXT); ELSE RETURN NEXT (23::INTEGER, 42::INTEGER, 'abc'::TEXT); RETURN NEXT (42::INTEGER, 23::INTEGER, 'xyz'::TEXT); END IF; RETURN; END; $function$; CREATE FUNCTION testing=# SELECT * FROM rr(2) f(a INTEGER, b INTEGER, c TEXT); a | b | c ----+----+----- 23 | 42 | abc 42 | 23 | xyz (2 rows) testing=# SELECT * FROM rr(1) f(x TEXT, y TEXT); x | y ----+---- k1 | v1 k2 | v2 (2 rows) Regards, Christoph -- Spare Space
