Question

我有这个选择Case SQL语句，用于计算给定数量的总体积。

SELECT
DropshipPackinglist.CaseNumber as 'CASE NO.',  
DropshipPackinglist.ItemNumber as 'BOM NO.', 
DropshipPackinglist.Quantity as 'QTY',
                      CASE 
                      WHEN DropshipPackinglist.Quantity >=31 and DropshipPackinglist.Quantity <= 36 then '1090x730x1460'
                      WHEN DropshipPackinglist.Quantity >=25 and DropshipPackinglist.Quantity <= 30  then '1090x730x1230'
                      WHEN DropshipPackinglist.Quantity >=19 and DropshipPackinglist.Quantity <= 24  then '1090x730x1000'
                      WHEN DropshipPackinglist.Quantity >=13 and DropshipPackinglist.Quantity <= 18  then '1090x720x790'
                      WHEN DropshipPackinglist.Quantity >=7 and DropshipPackinglist.Quantity <= 17  then '1090x720x570'
                      WHEN DropshipPackinglist.Quantity >=1 and DropshipPackinglist.Quantity <= 6  then '1090x720x350'

                      ELSE 'Unkown' 
                      end
                      as 'TOTAL VOLUME (MM3)'                                      

FROM         DropshipPackinglist INNER JOIN
                      HuaweiDescription ON DropshipPackinglist.ItemNumber = HuaweiDescription.ItemNumber

WHERE     (DropshipPackinglist.BatchCode LIKE '%0005041007100AHWA11HG')

-------------------------------------------------------------------------------------------
Result:

CaseNumber ItemNumber      Quantity  TotalVolume
1     52411573  5   1090x720x350
1     52411576  20  1090x730x1000
2     52411576  36  1090x730x1460

-------------------------------------------------------------------------------------------

现在，我想将casenumber和结果分组，只有一个总容量。

结果就是这个。

CaseNumber ItemNumber      Quantity  TotalVolume
1     52411573  5   1090x730x1230  -- sum(casenumber 1)=25
1     52411576  20  1090x730x1230  --
2     52411576  36  1090x730x1460

如何解决这个问题......谢谢。

如果每个caseNumber只需要一行，那么使用

SELECT CaseNumber, Quantity, SUM(ItemNumber) TotalVolume 
FROM (...YourOriginalQuery...)
GROUP BY CaseNumber, Quantity

如果您需要所有行但又想报告每个案例编号的总数，请使用以下查询：

SELECT CaseNumber, ItemNumber, Quantity,
                 SUM(ItemNumber) OVER(PARTITION BY CaseNumber) TotalVolume
    FROM   (SELECT DropshipPackinglist.CaseNumber, DropshipPackinglist.ItemNumber,
                                    DropshipPackinglist.Quantity,
                                    CASE
                                         WHEN DropshipPackinglist.Quantity >= 31
                                                    AND DropshipPackinglist.Quantity <= 36 THEN
                                            '1090x730x1460'
                                         WHEN DropshipPackinglist.Quantity >= 25
                                                    AND DropshipPackinglist.Quantity <= 30 THEN
                                            '1090x730x1230'
                                         WHEN DropshipPackinglist.Quantity >= 19
                                                    AND DropshipPackinglist.Quantity <= 24 THEN
                                            '1090x730x1000'
                                         WHEN DropshipPackinglist.Quantity >= 13
                                                    AND DropshipPackinglist.Quantity <= 18 THEN
                                            '1090x720x790'
                                         WHEN DropshipPackinglist.Quantity >= 7
                                                    AND DropshipPackinglist.Quantity <= 17 THEN
                                            '1090x720x570'
                                         WHEN DropshipPackinglist.Quantity >= 1
                                                    AND DropshipPackinglist.Quantity <= 6 THEN
                                            '1090x720x350'
                                         ELSE
                                            'Unkown'
                                    END AS 'TOTAL VOLUME (MM3)'

;with SuperSelect as 
(
 SELECT  dpl.CaseNumber as 'CASE NO.'
     ,dpl.ItemNumber as 'BOM NO.'
     ,dpl.Quantity as 'QTY'
     ,CASE WHEN dpl.Quantity >= 31 and dpl.Quantity <= 36 then '1090x730x1460'
     WHEN dpl.Quantity >= 25 and dpl.Quantity <= 30 then '1090x730x1230'
     WHEN dpl.Quantity >= 19 and dpl.Quantity <= 24 then '1090x730x1000'
     WHEN dpl.Quantity >= 13 and dpl.Quantity <= 18 then '1090x720x790'
     WHEN dpl.Quantity >= 7 and dpl.Quantity <= 17 then '1090x720x570'
