GROUP BY에 포함하지 않고 CASE 문에 무언가를 넣는 방법

Question

일부 정보를 수집하기 위해 쿼리 작업을하고 있으며 약간의 문제가 있습니다.

본인의 쿼리에서 CASE 문을 사용하여 측정 단위를 살펴보고 단위가 하나인지 다른지 여부에 따라 계산합니다.

내 문제는 내가 특정 레코드를보고있을 때, 단지 1로만 표시하고 싶을 때 2 레코드로 표시하지만 둘 다에서 수치를 합치는 것입니다.

불행하게도 2 개의 레코드가 표시되는 이유는 내가 유닛에 그룹을 가져야하기 때문입니다. 그리고 그들은 서로 다르기 때문에 2 라인 이상으로 나뉘어져 있습니다.

내 질문은 이것이다 :

Select 
C.CaseID, 
DATEPART(Year,C.ResolvedDate) 'Year', 
DATENAME(Month,C.ResolvedDate) 'Month', 
CASE 
    WHEN 
     I.ItemGroupID IN ('FGBCTFLR','FGBCTFLD','FGBCTLIS','FGBCTSAM','FGBCTSEC') THEN 'ManufacturedCeramics' 
    WHEN 
     I.ItemGroupID = 'FGBCTGLS' THEN 'ManufacturedGlass' 
    WHEN 
     I.ItemGroupID IN ('FGFACTAG','FGFACTFLD','FGFACTFLR','FGFACTLIS','FGTOOLS') THEN 'Factored' 
End as 'Category', 
COALESCE(CASE WHEN D.UnitID = 'BOX' THEN 
    SUM(D.QtyAffected * I.BCT_Product_Qty/(1/NULLIF((convert(decimal(18,3),I.BCT_Product_Width)/1000 * convert(decimal(18,3),I.BCT_Product_Height)/1000),0))) 
ELSE 
    SUM(D.QtyAffected/(1/NULLIF((convert(decimal(18,3),I.BCT_Product_Width)/1000 * convert(decimal(18,3),I.BCT_Product_Height)/1000),0))) 
End,0) as 'M2 Affected', 
C.CostReplacementTile + C.CostRedelivery + C.CostCredit + C.CostRefixing + C.CostVoucher 'Cost' 

From BCTComplaintRegister C 

Left Join BCTComplaintProductRegister D 
On D.CaseID = C.CaseID 

Left Join InventTable I 
On I.ItemID = D.ItemID 

Left Join BCTTileSize T 
On T.TileSizeID = I.BCTTileSize 

Where 
DATEDIFF(M,C.ResolvedDate,GETDATE()) <= 12 
And C.QAOutcome IN (1,2,5) 
And C.Status = '4' 
AND C.CaseID = 'CE20300' 

Group By 
    DATEPART(Year,C.ResolvedDate), 
    DATENAME(Month,C.ResolvedDate), 
    I.ItemGroupID, 
    C.CaseID, 
    C.CostReplacementTile, 
    c.costredelivery, 
c.costcredit, 
c.costrefixing, 
c.costvoucher, 
d.unitid 

Order By 
    C.CaseId 

결과는 다음과 같습니다 :

CaseID: CE20300, CE20300 <br> 
Year: 2016, 2016<br> 
Month: April, April<br> 
Category: ManCer, ManCer<br> 
M2 Affected: 23.56, 0.81 
Cost: 2292, 2292 

(죄송합니다 여기에 테이블을 할 방법을 잘하지 않음). 한 줄로 표시하려면이 값이 필요하지만 두 값의 합계가 M2 인 경우 비용은 동일하게 유지되어야합니다.

어떻게하면됩니까?

불명의 점이 있으면 죄송합니다.

COALESCE 식을 unitid에 그룹화 된 하위 쿼리로 변환 할 수 있습니까?

Select 
C.CaseID, 
DATEPART(Year,C.ResolvedDate) 'Year',

    WHEN 
     I.ItemGroupID IN ('FGFACTAG','FGFACTFLD','FGFACTFLR','FGFACTLIS','FGTOOLS') THEN 'Factored' 
End as 'Category', 
sum(D.M2Affected) as 'M2 Affected', 
C.CostReplacementTile + C.CostRedelivery + C.CostCredit + C.CostRefixing + C.CostVoucher 'Cost'

마지막 2 개의 선택 쿼리가 작동하면 병합 할 수 있습니다.
