每个项目编号的值总和？

Question

我写了sql server query，它给了我这个结果

在这里您可以看到ITEMNO在重复，我想要对TOTALQUANTITYUSE和TOTALQUANTITYSALE两列的itemno求和。 例如，我只希望在每个itemno上输入一个条目，例如ITEMNO 220415在单行中仅显示一次，并且此项目编号的值总和将显示在一行上。希望您理解。

SELECT a.ITEMNO,(COUNT(a.ITEMNO)*a.QTY) as 'Total Quantity USE', 
(COUNT(WR.ITEMEMPNO)*WR.QTY) AS 'Total Quantity Sale'
 FROM InvItems a
  inner join WRKTRANS WR ON WR.ITEMEMPNO=a.ITEMNO
  inner join InvHdr HR ON HR.INVTYPE =a.TYPE
  WHERE a.ITEMNO IS NOT NULL AND a.TYPE='3'
  group by a.ITEMNO,WR.QTY,a.QTY

Answer 1

类似的事情应该起作用（基于itemno汇总记录并显示总和）-

;WITH CTE AS (
    SELECT a.ITEMNO,(COUNT(a.ITEMNO)*a.QTY) as 'Total Quantity USE', 
    (COUNT(WR.ITEMEMPNO)*WR.QTY) AS 'Total Quantity Sale'
     FROM InvItems a
      inner join WRKTRANS WR ON WR.ITEMEMPNO=a.ITEMNO
      inner join InvHdr HR ON HR.INVTYPE =a.TYPE
      WHERE a.ITEMNO IS NOT NULL AND a.TYPE='3'
      group by a.ITEMNO,WR.QTY,a.QTY)
    SELECT ITEMNO,SUM([Total Quantity USE]),SUM([Total Quantity Sale])
    FROM CTE
    GROUP BY ITEMNO

Answer 2

SELECT ItemNo, SUM([Total Quantity USE]) AS "Total Quantity USE", SUM([Total Quantity Sale]) AS "Total Quantity Sale"
FROM (your_query) AS q
GROUP BY ItemNo

Answer 3

使用整合功能

    select itemno,sum([Total Quantity USE] totalQty),
   sum( [Total Quantity Sale] ) as TotalSale,
   count(itemno) as total_iteam from yourtable t    
    group by  itemno 

Answer 4

您需要编写多个CTE语句，以便在SELECT语句中具有额外的属性。 @Abhishek代码中的附加内容很少，请检查以下内容。
