PostgreSQL function returning multiple result sets

Question

Is it possible to return multiple result sets from a Postgres function, like in MSSQL:

CREATE PROCEDURE test

AS

SELECT * FROM first_table

SELECT * FROM se         


        

Answer 1

CREATE OR REPLACE FUNCTION "pr_GetCustomersAndOrders"()
RETURNS SETOF refcursor AS
$BODY$DECLARE
customerRC refcursor;
orderRC refcursor;
BEGIN
open customerRC FOR
SELECT * FROM customers;
RETURN NEXT customerRC;

open orderRC FOR
SELECT * FROM orders;
RETURN NEXT orderRC;
RETURN;
END;$BODY$
LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION "pr_GetCustomersAndOrders"() OWNER TO postgres;

I.o.w. using refcursors :)
