基於同一視圖中的另一列在SQL視圖中插入總和

Question

我正嘗試在用戶中爲SQL創建一個視圖。 （如下所示）在這裏，我想Sum dbo.WipPartBook.QtySupplied的值，當列dbo.WipPartBook.Job的值是相同的。

SELECT  TOP (100) PERCENT dbo.vwSTKCF.StockCode, dbo.vwSTKCF.Cavity, dbo.vwSTKCF.Mass, dbo.vwSTKCF.Material, dbo.WipPartBook.Job, 
        dbo.WipPartBook.QtySupplied, dbo.WipPartBook.TrnDate 
FROM   dbo.WipPartBook INNER JOIN 
        dbo.InvMaster INNER JOIN 
        dbo.WipMaster ON dbo.InvMaster.StockCode = dbo.WipMaster.StockCode ON dbo.WipPartBook.Job = dbo.WipMaster.Job LEFT OUTER JOIN 
        dbo.vwSTKCF ON dbo.InvMaster.StockCode = dbo.vwSTKCF.StockCode 
WHERE  (dbo.vwSTKCF.StockCode = 'SC2020-01-00') 
ORDER BY dbo.vwSTKCF.StockCode 

Answer 1

您使用的是哪種SQL Server版本？如果它是當前一個你應該考慮的窗口功能，允許，除其他外，通過「分組」列（dbo.WipPartBook.Job）分區總數 看看這裏的介紹：Microsoft BOL

編輯：增加了一個（未經測試）例如：

SELECT  TOP (100) PERCENT dbo.vwSTKCF.StockCode, dbo.vwSTKCF.Cavity, dbo.vwSTKCF.Mass, dbo.vwSTKCF.Material, dbo.WipPartBook.Job, 
       dbo.WipPartBook.QtySupplied, dbo.WipPartBook.TrnDate, 

SUM(dbo.WipPartBook.QtySupplied) OVER (PARTITION BY dbo.WipPartBook.Job) AS Total 

FROM   dbo.WipPartBook INNER JOIN 
       dbo.InvMaster INNER JOIN 
       dbo.WipMaster ON dbo.InvMaster.StockCode = dbo.WipMaster.StockCode ON dbo.WipPartBook.Job = dbo.WipMaster.Job LEFT OUTER JOIN 
       dbo.vwSTKCF ON dbo.InvMaster.StockCode = dbo.vwSTKCF.StockCode 
WHERE  (dbo.vwSTKCF.StockCode = 'SC2020-01-00') 
ORDER BY dbo.vwSTKCF.StockCode 

Answer 2

SELECT dbo.WipPartBook.Job, sum(dbo.WipPartBook.QtySupplied)  
    FROM dbo.WipMaster  
    JOIN dbo.WipPartBook 
      ON dbo.WipPartBook.Job = dbo.WipMaster.Job 
WHERE dbo.WipMaster.StockCode = 'SC2020-01-00' 
GROUP BY dbo.WipPartBook.Job 
Order BY dbo.WipPartBook.Job
