我如何使用OVER和ORDER BY

Question

我无法理解此代码的错误。

CODE：

SELECT 
    CariID, HesapID, BTrh, BCinsiID, BNo, Acklm, VdTrh, mTrh, BorcT, AlacakT, 
    SUM(BorcT) OVER (PARTITION BY CariID, HesapID ORDER BY BTrh, BNo, mTrh) AS TopBorcT, 
    SUM(AlacakT) OVER (PARTITION BY CariID, HesapID ORDER BY BTrh, BNo, mTrh) AS TopAlacakT 
FROM 
    tCariH 

错误：

Msg 102, Level 15, State 1, Line 3

Incorrect syntax near 'order'.

Answer 1

有了这样SUM聚合函数，you don't use ORDER BY in the OVER clause - 你只需要使用PARTITION功能。该ORDER用于排名功能：

只需修改以消除你都聚集在ORDER，你应该罚款。

Answer 2

ID  AccountID  Quantity 
1   1    10   Sum = 10 
2   1    5    = 10 + 5 = 15 
3   1    2    = 10 + 5 + 2 = 17 
4   2    7    = 7 
5   2    3    = 7 + 3 = 10 

SELECT ID, AccountID, Quantity, 
     SUM(Quantity) OVER (PARTITION BY AccountID) AS TopBorcT, 
FROM tCariH

显然，这在SQL Server 2008中不支持，但它是在SQL Server支持2012
