如何在选择SQL中嵌套大小写？

Question

我有这个选择Case SQL语句来计算给定数量的totalvolume。

---

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 

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

是现在，我想组casenumber和只有一个totalvolume结果。

而结果将是这一个。

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one..thanks的问候。

;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' 
    WHEN dpl.Quantity >= 1 and dpl.Quantity <= 6 then '1090x720x350' 
    ELSE 'Unkown'

FROM DropshipPackinglist dpl 
INNER JOIN HuaweiDescription hd ON dpl.ItemNumber = hd.ItemNumber 
WHERE (dpl.BatchCode LIKE '%0005041007100AHWA11HG') 
) 
select *, sum([QTY]) over (partition by ss.[CASE NO.]) [TotalVolume] 
from SuperSelect ss

如果你需要每caseNumber只有一行，然后使用

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

如果你需要的所有行，但要还报告则总每箱数量使用以下查询：

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)' 
        FROM DropshipPackinglist 
        INNER JOIN HuaweiDescription 
        ON  DropshipPackinglist.ItemNumber = HuaweiDescription.ItemNumber 
        WHERE (DropshipPackinglist.BatchCode LIKE '%0005041007100AHWA11HG'))
