请问在oracle下如何实现sql server的如下功能？
CREATE   FUNCTION   CheckGoodsNo   (@GoodNo   varchar(20))    
RETURNS   @Goods   TABLE
(
    tableid   varchar(6),
    tablename   varchar(26)  
)
AS
BEGIN
            insert   @Goods
                select   distinct   'a001 '   as   AA,   '客户商品价格档 '   as   BB  
                FROM   a
                WHERE   a002=@GoodNo  
            ......                    
            RETURN          
END

------解决方案--------------------
--上面的有点错误

CREATE OR REPLACE PROCEDURE ll_02 (
p_GoodNo in varchar2(20),
p_cursor OUT sys_refcursor) IS
BEGIN
OPEN p_cursor FOR
select distinct 'a001 ' as AA, '客户商品价格档 ' as BB
FROM a
WHERE a002=p_GoodNo;

END ll_02;
