SQL - случай, когда на той же строке

Question

У меня есть проблема с запросом, который включает в себя несколько Whens тематических

 SELECT DISTINCT 
      ,-1*(SUM(ISNULL(DB.[Commission_Bal],0)) + SUM(ISNULL(UP.AMOUNT,0))) AS [Commission_Bal] 
      ,DATEDIFF(DAY,DB_CD.Create_Date,'20170123') AS Days_In_Neg_Bal 
      ,CASE WHEN DOC.DocumentTypeCode = 'MCS30' THEN DOC.DocumentDate END AS '30 Day Letter' 
      ,CASE WHEN DOC.DocumentTypeCode = 'MCS60' THEN DOC.DocumentDate END AS '60 Day Letter' 
      ,CASE WHEN DOC.DocumentTypeCode = 'MCS90' THEN DOC.DocumentDate END AS '90 Day Letter' 
      ,CASE WHEN DOC.DocumentTypeCode = 'MCS20' THEN DOC.DocumentDate END AS '120 Day Letter' 
      ,DB.[Cycle_Date] 

Он возвращает отдельные строки, но я хотел бы результат, чтобы иметь их на той же строке. Она возвращает верхнее изображение, но я хотел бы, чтобы вернуть результаты, близкие к нижнему изображению

Answer 1

Сделать это условное объединение

SELECT (-1*(SUM(ISNULL(DB.[Commission_Bal],0)) + SUM(ISNULL(UP.AMOUNT,0))))/count(*) AS [Commission_Bal] 
     ,DATEDIFF(DAY,DB_CD.Create_Date,'20170123') AS Days_In_Neg_Bal 
     ,Max(CASE WHEN DOC.DocumentTypeCode = 'MCS30' THEN DOC.DocumentDate END) AS '30 Day Letter' 
     ,Max(CASE WHEN DOC.DocumentTypeCode = 'MCS60' THEN DOC.DocumentDate END) AS '60 Day Letter' 
     ,Max(CASE WHEN DOC.DocumentTypeCode = 'MCS90' THEN DOC.DocumentDate END) AS '90 Day Letter' 
     ,Max(CASE WHEN DOC.DocumentTypeCode = 'MCS20' THEN DOC.DocumentDate END) AS '120 Day Letter' 
     ,DB.[Cycle_Date] 
From YourTable 
Group By -1*(SUM(ISNULL(DB.[Commission_Bal],0)) + SUM(ISNULL(UP.AMOUNT,0))) 
     ,DATEDIFF(DAY,DB_CD.Create_Date,'20170123') 
     ,DB.[Cycle_Date] 

EDIT - Вариант 2:

Select [Commission_Bal] 
     ,[Days_In_Neg_Bal] 
     ,[30 Day Letter] = max([30 Day Letter]) 
     ,[60 Day Letter] = max([60 Day Letter]) 
     ,[60 Day Letter] = max([90 Day Letter]) 
     ,[120 Day Letter] = max([120 Day Letter]) 
     ,[Cycle_Date] 
From (
     SELECT DISTINCT 
        -1*(SUM(ISNULL(DB.[Commission_Bal],0)) + SUM(ISNULL(UP.AMOUNT,0))) AS [Commission_Bal] 
        ,DATEDIFF(DAY,DB_CD.Create_Date,'20170123') AS Days_In_Neg_Bal 
        ,CASE WHEN DOC.DocumentTypeCode = 'MCS30' THEN DOC.DocumentDate END AS '30 Day Letter' 
        ,CASE WHEN DOC.DocumentTypeCode = 'MCS60' THEN DOC.DocumentDate END AS '60 Day Letter' 
        ,CASE WHEN DOC.DocumentTypeCode = 'MCS90' THEN DOC.DocumentDate END AS '90 Day Letter' 
        ,CASE WHEN DOC.DocumentTypeCode = 'MCS20' THEN DOC.DocumentDate END AS '120 Day Letter'

      From YourTable 
     ) A 
Group By [Commission_Bal] 
     ,[Days_In_Neg_Bal]
