如何总结的价值为每

Question

我有表如下：

ClientNUM PIECES DID 
NEWAGENC  10  5 
NEWAGENC  25  5 
WAY   30  4 
CHCAH  20  2 
AVC   21  2 

我想结果这三点的价值为每个客户端如下

CleintNUM  Pieces DID 
    NEWAGENC  35  5 
    WAY   30  4 
    CHCAH   20  2 
    AVC   21   2 

我查询

SELECT 
     CLIENTNUM, 
     DID, 
     PIECES, 
     GETDATE() AS CURRENTDATE, 
     SUM(PIECES) 
FROM Mytable 
GROUP BY CLIENTNUM, DISPID, PIECES 

那么我怎么能在我的查询中为每个CLIENTNUM做总和意思是DISTINCT For e像NEWAGENC ACH客户件具有值10和第二排25这样的作品将是10 + 25 = 35

Answer 1

通过PIECES不群，如果你想总IT

SELECT CLIENTNUM, 
     DID, 
     PIECES, 
     GETDATE() AS CURRENTDATE, 
     SUM(PIECES) 
FROM Mytable 
GROUP BY CLIENTNUM, DISPID
