根据不同的分组条件计算总数

Question

我有两个表OD和ODD。我需要找到已发货的总量，并且 对于特定的交付，每天每部分每天要运送14天。从report_date-7到report_date + 7（用于分组和汇总），printing_date将用于shipped_qty，exp_shipping_date将用于to_ship qty。

结合两个表的结果

预期产量

预期结果已纠正

我不清楚如何获得日期列在REPORT_DATE -7至REPORT_DATE + 7之间，以及分别与PRINTING_DATE和EXP_SHIP_DATE有关的qty_shipped和qty_to_ship总数。

Answer 1

我可以看到一些简化此问题的步骤。我假设您不希望使用datetime，而只考虑没有时间的日期。因此我们只需要获取带有日期的表即可，以使问题更容易解决。

第二件事，您有两个日期，并且想要按日期分组，因此让我们每个人单独分组，然后将结果集合并回去。

第三，您需要的日期范围是-7到+7。好的，让我们尝试将其分解为较小的和平，并获得一些结果。

 DECLARE @REPORT AS DATETIME='2019-06-19 01:00:01.000'
 Declare @Report_min as date=DATEADD(DAY,-7,@REPORT)
 Declare @Report_max as date=DATEADD(DAY,7,@REPORT)
 Declare @Plant as varchar(100)='1173'



 ;with ODcte as (
     --to get all our datetimes to dates only (getting the time out)
      select   
          OUTBOUNDDELIVERY 
         ,PLANT 
         ,cast(PRINTING_DATE as date) SHIP_DATE
         ,cast(EXP_SHIP_DATE as date) EXP_SHIP_DATE
      from OD_TABLE
  ),shipped as (
        --group only by shipped and get the sum
        select PLANT,PARTS,SHIP_DATE,SUM(QTY_PICKED) SHIPPED_Qty
            from ODD_TABLE ODD
                 INNER JOIN ODcte as OD ON ODD.OUTBOUNDDELIVERY = OD.OUTBOUNDDELIVERY
            WHERE PLANT = @Plant AND SHIP_DATE between  @Report_min and @Report_max 
            Group By PLANT,PARTS,SHIP_DATE
    ),Exp_ship as (
          --group only by exp to ship and get the sum
        select PLANT,PARTS,EXP_SHIP_DATE,SUM(QTY_SAP) Exp_SHIPPED_Qty
            from ODD_TABLE ODD
                 INNER JOIN ODcte as OD ON ODD.OUTBOUNDDELIVERY = OD.OUTBOUNDDELIVERY
            WHERE PLANT = @Plant AND EXP_SHIP_DATE between  @Report_min and @Report_max 
            Group By PLANT,PARTS,EXP_SHIP_DATE
    ),DateRange as (
        --lets generate a list of days
        select @Report_min [date] union all
        select dateadd(day,1,[date]) from DateRange where date<@Report_max
    ),shippedWithAllReportDays as(
    select PLANT,PARTS,DateRange.[date],SHIPPED_Qty
     From DateRange
        left outer join shipped on shipped.SHIP_DATE=DateRange.[date]
    ),exp_shippWithAllReportDays as(
        select PLANT,PARTS,DateRange.[date],Exp_SHIPPED_Qty
        From DateRange
            left outer join Exp_ship on Exp_ship.EXP_SHIP_DATE=DateRange.[date]
    )
    select 
        s.PLANT,s.PARTS,s.[date],SHIPPED_Qty,Exp_SHIPPED_Qty
     from shippedWithAllReportDays s
        left outer join exp_shippWithAllReportDays e on 
            s.PLANT=e.PLANT and
            s.PARTS=e.PARTS and
            s.[date]=e.[date]

请尝试一下，希望对您有所帮助。
