如何將輸出結果更改爲零的sql腳本？

Question

這是我的腳本

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 

結果是

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 

我想讓第二行（392）的值只有0。我在這裏使用SQL 2000。

該查詢會給你想要的結果：

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 

可是我最好還是要做到這一點的客戶端，而不是服務器端
