Question

我正在尝试在SQL中为用户创建一个视图。（如下图所示）在这里，我希望在dbo.WipPartBook.Job列的值相同时，将dbo.WipPartBook.QtySupplied的值加起来。

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

您使用的是哪个SQL Server版本？如果它是当前的，你应该查看窗口函数，其中包括由“分组”列（dbo.WipPartBook.Job）分区的总数。在这里查看介绍：Microsoft BOL

编辑：添加了一个（未经测试的）示例：

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

基于同一视图中的另一列在SQL视图中插入Sum
