Hi,
How do I return a result set? Is there a better way in 'plpgsql' than
the one described below?
I do not want to make a select from a function(which pretty useful in
many cases):
SELECT * FROM getfoo();
, but I want to just call the function with SELECT getfoo();
--DROP FUNCTION getfoo();
--DROP type compfoo;
CREATE TYPE compfoo AS (f1 integer,f2 integer);
CREATE OR REPLACE FUNCTION getfoo() RETURNS SETOF compfoo
AS
$BODY$
declare
ret_row record;
BEGIN
FOR ret_row IN SELECT id,mun_id FROM mytable LOOP
RETURN next ret_row;
END LOOP;
RETURN;
END;
$BODY$
LANGUAGE 'plpgsql';
