Question

此代码为我提供了重复的结果。

SELECT store_sp.Partnumber
     , store_sp.ID
     , dbo.installed_sp.Installed_qty
     , dbo.store_sp.qty
FROM dbo.store_sp  
INNER JOIN dbo.installed_sp 
   ON dbo.store_sp.PartID = dbo.installed_sp.part_id 
  and store_sp.Partnumber = installed_sp.PartNumber

我该如何解决它 https://ibb.co/n38xQk

你可能想要一个GROUP BY;

这将汇总您调用的行中的数量＆＃39;重复＆＃39;。这是我们可以从您的问题中猜出的最好的，所以请尽量提供更多信息......

SELECT store_sp.Partnumber
     , store_sp.ID
     , sum(dbo.installed_sp.Installed_qty) AS TotalInstalledQuantity
     , sum(dbo.store_sp.qty) as TotalQuantity
FROM dbo.store_sp  
INNER JOIN dbo.installed_sp 
   ON dbo.store_sp.PartID = dbo.installed_sp.part_id 
  and store_sp.Partnumber = installed_sp.PartNumber
GROUP BY
     store_sp.Partnumber
     , store_sp.ID

这个查询给了我重复的数据
