在存儲過程中使用Group By子句

Question

我有一個存儲過程，其中iam將InvoiceValue作爲一個字段。我有不同的發票值對應於1個fileid.I想要獲得與每個fileid對應的發票值的總和。在這裏使用組？ 這裏是我的存儲過程

set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
GO 
ALTER Procedure [dbo].[rptGGM] 
(
    @FromDate varchar(50), 
    @ToDate varchar(50), 
    @PartyID int, 
    @WID int 

) 

As 
DECLARE @WhereStr VarChar(800) 

SET @FromDate = LTRIM(RTRIM(@FromDate)) 
SET @ToDate = LTRIM(RTRIM(@ToDate)) 

SET @WhereStr = 
    CASE @WID 
     WHEN 23 THEN 'WHERE G.PartyID='+LTRIM(str(@PartyID)) +' AND ((D.ATASea >='''+@FromDate+''' And D.ATASea<='''+@ToDate+'''))' 
     WHEN 7 THEN 'WHERE G.PartyID='+LTRIM(str(@PartyID)) +' AND ((D.ATASea >='''+@FromDate+''' And D.ATASea<='''+@ToDate+''')) AND A.WorkID='+LTRIM(str(@WID)) 
     WHEN 6 THEN 'WHERE G.PartyID='+LTRIM(str(@PartyID)) +' AND ((D.ATASea >='''+@FromDate+''' And D.ATASea<='''+@ToDate+''')) AND A.WorkID='+LTRIM(str(@WID)) 
     WHEN 11 THEN 'WHERE G.PartyID='+LTRIM(str(@PartyID)) +' AND ((D.ATASea >='''+@FromDate+''' And D.ATASea<='''+@ToDate+''')) AND A.WorkID='+LTRIM(str(@WID)) 
     WHEN 12 THEN 'WHERE G.PartyID='+LTRIM(str(@PartyID)) +' AND ((D.ATASea >='''+@FromDate+''' And D.ATASea<='''+@ToDate+''')) AND A.WorkID='+LTRIM(str(@WID)) 

    END

這裏最快的實施方法是，不使用GROUP BY。我會在你的SELECT中使用一個SubQuery來執行發票的SUM。

取出LEFT JOIN到發票，然後relace在選擇L.Amount符合子查詢如下

(SELECT SUM(Amount) FROM Invoice WHERE Invoice.FileID = A.FileID and Invoice.Incoterm = 'CIF') [Invoice Value] 

如果您想使用GROUP BY執行SUM，那麼你要麼需要GROUP在您選擇的所有其他列上，或者在VIEW中（可能嵌套）執行GROUP。
