Question

所以我在.net中为图表构建查询。我的问题是，我不知道如何将月份加到下个月。所以这是我在下面的查询以及我从中获得的内容。

Answer 1

您可以使用count() over()

执行此操作

select 
     [Year]      = datepart(year , LastModified)
   , [Month]     = datepart(Month, LastModified) 
   , [MonthName] = datename(Month, LastModified) 
   , DeployedThisMonth = count(*)
   , DeployedSoFar = count(*) over (
        order by datepart(year , LastModified)
               , datepart(Month, LastModified)
     )
  from [InventoryDatabase].[dbo].[Hardware_RefreshList]
  where Asset_Type = 'Laptop' 
    and status = 'Completed' 
    and Department != 'snbc' 
    and datepart(year, LastModified) = 2017
  group by 
      datepart(Month, LastModified)
    , datepart(year, LastModified)
    , Month(LastModified)
    , datename(Month, LastModified)
    --, dateadd(month, datediff(month, 0, LastModified), 0)
  order by datepart(Month, LastModified)

Microsoft SQL每月添加到查询
