[转].net 调用oracle存储过程返回多个记录集

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;
