存储过程： 

CREATE OR REPLACE PROCEDURE p_query_cs (
p_infotype IN VARCHAR2,
p_fromareacode IN VARCHAR2,
p_toareacode IN VARCHAR2,
p_keytype IN NUMBER,
r_cursor1 OUT sys_refcursor, --结果集
r_cursor2 OUT sys_refcursor --结果集
)
IS
BEGIN
OPEN r_cursor1 FOR
SELECT *
FROM permit_menu; 

OPEN r_cursor2 FOR
SELECT *
FROM permit_privilege;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;
WHEN OTHERS
THEN
RAISE;
END p_query_cs;
