oracle在执行SQL语句是。有同名变量怎么绑定啊

[ighack]

SELECT *
  FROM (SELECT T_GDS.OWNER_NO,
               T_GDS.GOODS_NO,
               T_GDS.GOODS_NAME,
               T_GDS.GOODS_LENGTH,
               T_GDS.GOODS_WIDTH,
               T_GDS.GOODS_HEIGHT,
                T_GDS.MARKETINGAUTHORISATIONHOLDER,
               (SELECT MIN(T_STK.DISPLAY_LOCATION)
                  FROM VIW_FD_STOCK T_STK
                 WHERE T_STK.GOODS_ID = T_GDS.GOODS_ID) DISPLAY_LOCATION
          FROM FD_GOODS T_GDS
          LEFT JOIN REC_GOODS_RST T_RST
            ON T_GDS.GOODS_ID = T_RST.GOODS_ID
         WHERE T_GDS.IS_AVAILABLE = 'Y'
           AND T_RST.LWH_MOD_FLG IS NULL
           AND T_GDS.IS_GIFT = 'N'
           AND (T_GDS.GOODS_LENGTH < = 1 OR T_GDS.GOODS_WIDTH < = 1 OR
               T_GDS.GOODS_HEIGHT < = 1)
           AND EXISTS
         (SELECT 1 FROM FD_STOCK T WHERE T.GOODS_ID = T_GDS.GOODS_ID))
 WHERE (:GOODS_NO IS NULL OR GOODS_NO LIKE '%' || :GOODS_NO || '%')
   AND (:GOODS_NAME IS NULL OR GOODS_NAME LIKE '%' || :GOODS_NAME || '%') 
   AND (:DISPLAY_LOCATION IS NULL OR DISPLAY_LOCATION LIKE '%' || :DISPLAY_LOCATION || '%') 
   ORDER BY DISPLAY_LOCATION,GOODS_NO  

我是这样做的，选生成perpareCall对像
call = conn.prepareCall(SQL);

然后换名字绑定
call.setObject("GOODS_NO", obj.get("Value"), obj.getInteger("Type"))
call.setObject("GOODS_NAME", obj.get("Value"), obj.getInteger("Type"))
call.setObject("DISPLAY_LOCATION", obj.get("Value"), obj.getInteger("Type"))

但程序报错
java.sql.SQLException: 索引中丢失 IN 或 OUT 参数:: 4

然后我有6个变量但是同名的。实际只有3个。我也绑定了三个。但还是报错。但在.NET里这个同名变量绑定是可以正常执行的

就算我把同名的变量绑定两次也不行。报同样的错误
