Question

我正在尝试查找重复项的数量，并在两个特定日期之间将它们相加。但由于分组，无法在having上实施日期标准。

任何帮助将不胜感激。这就是我试过的

  select AssociationBarcode, 
         count(*) 
    from ContainerInstruction
group by ContainerInstruction.AssociationBarcode
  having count (*) > 1 and 
         AssociationBarcode <> ''
   where CreatedDateTime between getdate() - 1 and getdate()

Answer 1

您可以使用内联注释尝试以下查询，其中服务器作为解释：

select 
         AssociationBarcode, 
         count(*) as [count],
         sum(yourColumnWhichNeedsToBeSummed) as [Sum]
      from 
         ContainerInstruction
      -- Note that the Where clause containing dates is applied before grouping. 
      -- This also means that your count and sum will be affected by where clause.
      where 
         CreatedDateTime between getdate() - 1 and getdate() and 
         AssociationBarcode <> ''
      group by 
         ContainerInstruction.AssociationBarcode
      having 
        count (*) > 1
