聚合不應出現在WHERE子句中，即使我沒有條件，同時使用SUM

Question

我有以下查詢

SELECT A.*,SUM(ISNULL(B.DEPTRAN_DEPOSIT,0)-ISNULL(B.DEPTRAN_WITHDRAWAL,0)) as BALANCE 
FROM DEPOSITFDMASTER A 
INNER JOIN DEPOSITTRANSACTION B ON A.DEPSUBTYPE_ID=B.DEPSUBTYPE_ID AND A.FD_ID=B.DEPOSIT_DATAID WHERE SUM(ISNULL(B.DEPTRAN_DEPOSIT,0)-ISNULL(B.DEPTRAN_WITHDRAWAL,0))>10 

這個當我嘗試執行我會得到下面的錯誤。如果我刪除condtion，那麼查詢將正常工作。

An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference. 

P.S：DEPTRAN_DEPOSIT和DEPTRAN_WITHDRAWAL兩者都具有數據類型Decimal(18,2)。

任何幫助表示讚賞。

我建議你使用GROUP BY和HAVING。像這樣的東西

SELECT 
    A.* 
    ,SUM(ISNULL(B.DEPTRAN_DEPOSIT,0)-ISNULL(B.DEPTRAN_WITHDRAWAL,0)) as BALANCE 
FROM DEPOSITFDMASTER A 
INNER JOIN DEPOSITTRANSACTION B 
ON 
A.DEPSUBTYPE_ID=B.DEPSUBTYPE_ID 
AND  
A.FD_ID=B.DEPOSIT_DATAID 
GROUP BY [All columns in A] --like that A.Column1,A.COlumn2,....,A.ColumnN 
HAVING SUM(ISNULL(B.DEPTRAN_DEPOSIT,0)-ISNULL(B.DEPTRAN_WITHDRAWAL,0))>10
