在 SQL 服务器查询中获取按月数据

Question

我正在尝试按月获取数据，因为我已经创建了查询，但结果中有一些重复记录，如下所示，使用 SQL 服务器。

SELECT DM.deptdesc, 
   PIM.itemcode, 
   PIM.itemdesc, 
   Isnull(Sum(IM.issuedqty), 0) AS 'Issued', 
   Datename(month, IM.dt)       AS MONTH, 
   Year(IM.dt)                  AS year 
FROM  poitemmaster AS PIM 
   inner JOIN issuematerial AS IM 
                ON PIM.itemcode = IM.itemcode 
   LEFT OUTER JOIN departmentmaster AS DM 
                ON PIM.deptcode = DM.deptcode 
WHERE  PIM.itemcode = 'ICMEL00001' 
GROUP  BY DM.deptdesc, 
      PIM.itemcode, 
      PIM.itemdesc, 
      IM.issuedqty, 
      Datename(month, IM.dt), 
      Year(IM.dt)

我的查询return这个数据

但我想要这个

我想要按月计算的数量总和。我应该为此做什么？

Answer 1

从group by中移除issuedqty列，并在列列表中的相同列中添加一个SUM()

SELECT DM.deptdesc, 
   PIM.itemcode, 
   PIM.itemdesc, 
   Sum(ISNULL(IM.issuedqty, 0) AS 'Issued', 
   Datename(month, IM.dt)       AS MONTH, 
   Year(IM.dt)                  AS year 
FROM  poitemmaster AS PIM 
   inner JOIN issuematerial AS IM 
                ON PIM.itemcode = IM.itemcode 
   LEFT OUTER JOIN departmentmaster AS DM 
                ON PIM.deptcode = DM.deptcode 
WHERE  PIM.itemcode = 'ICMEL00001' 
GROUP  BY DM.deptdesc, 
      PIM.itemcode, 
      PIM.itemdesc, 
      Datename(month, IM.dt), 
      Year(IM.dt)
