sql - 如何将输出结果更改为 sql 脚本的零？

Question

这是我的脚本

   SELECT a.iPriority_num AS [TransNUM],b.sItem_nm as [Item],a.mSellingPrice_amt AS [aMT],
        SUM(c.mCash_amt) AS [CASH]
        ,SUM(c.mCCard_amt) AS [CC]
        ,SUM(c.mEPS_amt) AS [CEPS]
        ,SUM(c.mGCheque_amt) AS [GC]
        ,SUM(c.mCheque_amt) AS [OTHERS]
    FROM Table1 a
    LEFT JOIN Table2 b
    ON a.sPlu_cd=b.sPlu_cd
    LEFT JOIN Table3 c
    ON  a.iPriority_num=c.iPriority_num AND
    a.iBranch_num=c.iBranch_num 
    AND b.iCompany_typ=c.iCompany_typ
   WHERE a.IAPPLY_DT BETWEEN 20130701 AND 20130731
    AND a.iBranch_num=14
    AND a.iStatus_typ=1
    AND a.sSellUnit_CD='PC'
    AND a.IPRIORITY_NUM=118271
   GROUP BY 
   a.iPriority_num,b.sItem_nm,a.mSellingPrice_amt

结果是

   TransNUM Item  Price     Cash      CC      EPS    GC      others        
   118271   Item1 204.0000  392.0000 .0000  .0000   .0000   .0000
   118271   Item2 188.0000  392.0000 .0000  .0000   .0000   .0000

我只想将第二行（392）的值设为 0。我在这里使用 sql 2000。

此查询将给出您想要的结果：

SELECT a.iPriority_num AS [TransNUM],b.sItem_nm as [Item],a.mSellingPrice_amt AS [aMT],
      [CASH] = CASE WHEN ROW_NUMBER () OVER 
                  (ORDER BY a.iPriority_num,b.sItem_nm,a.mSellingPrice_amt) = 2 
               THEN 0 ELSE SUM(c.mCash_amt) END
      ,SUM(c.mCCard_amt) AS [CC]
      ,SUM(c.mEPS_amt) AS [CEPS]
      ,SUM(c.mGCheque_amt) AS [GC]
      ,SUM(c.mCheque_amt) AS [OTHERS]
 FROM Table1 a
 LEFT JOIN Table2 b
 ON a.sPlu_cd=b.sPlu_cd
 LEFT JOIN Table3 c
 ON  a.iPriority_num=c.iPriority_num AND
 a.iBranch_num=c.iBranch_num 
 AND b.iCompany_typ=c.iCompany_typ
WHERE a.IAPPLY_DT BETWEEN 20130701 AND 20130731
 AND a.iBranch_num=14
 AND a.iStatus_typ=1
 AND a.sSellUnit_CD='PC'
 AND a.IPRIORITY_NUM=118271
GROUP BY 
a.iPriority_num,b.sItem_nm,a.mSellingPrice_amt

但我最好在客户端而不是服务器端执行此操作
