SQL：數據透視表，其中包括總和和百分比

我試圖重新創建Tableau中的視圖作爲SQL中的視圖。它要求我旋轉基於一個月一個表，不僅總結了量，但我還需要通過保證金進行總結，並創建一個保證金％row.The所需的輸出是SQL：數據透視表，其中包括總和和百分比

BUSINESS_UNIT CLASS   JANUARY FEBRUARY MARCH 
202   Cost of Sales 100 (null)  60 
202   Revenue   200 80   (null) 
202   Margin   x  xx   xxx 
202   Margin %   x%  xx%   xxx%

我可以透視基於一個月，但如何在一個數據透視表中執行兩次總計，我怎麼去包括一個percenatge行呢？

代碼到目前爲止

SELECT 
    * 
FROM 
    (SELECT 
      [Business_Unit] 
      ,[Class] 
      ,Month as Period 
      ,[Amount] 
      --,Margin        
     FROM [sample_table] 
     where [Class] in ('Revenue','Cost of Sales'))AS T 
    PIVOT(SUM(Amount) 
      FOR Period IN ([January],[February],[March])) as Pvt

我不明白保證金％。這是3個月的總和的百分比嗎？因此，1月將是（300/440）或68.1％2月將是18.18 3月13.63？ – xQbert 2014-09-22 14:33:52

不是最漂亮的SQL我已經做到了。但這似乎工作...

它的作用是建立在你已經通過產生一個邊界線並增加了總列使用這條線，總那麼我們可以計算出％做了什麼的保證金。分組SETS允許我生成多行，小計和總計，因爲我知道生成的唯一附加行會有一個空類，所以我能夠在空類時將類的名稱設置爲邊界。

WITH CTE AS (
    SELECT 
     Business_Unit 
     ,case when class is NULL then 'Margin' else class end as Class 
     ,Sum(January) as January 
     ,Sum(February) as February 
     ,Sum(March) as march 
     ,Sum(coalesce(January,0)+coalesce(February,0)+coalesce(March,0)) as Total 
    FROM (
     SELECT 
     * 
     FROM 
     (SELECT 
       [Business_Unit] 
       ,[Class] 
       ,Month as Period 
       ,[Amount] 
       --,Margin        
      FROM [sample_table] 
      where [Class] in ('Revenue','Cost of Sales'))AS T 
     PIVOT(SUM(Amount) 
       FOR Period IN ([January],[February],[March])) as Pvt 
    ) as Base 
    GROUP BY Grouping sets 
    ((Business_Unit,Class,January,February,March, 
     coalesce(January,0)+coalesce(February,0)+coalesce(March,0)) 
    ,(Business_Unit) 
    )) 
    SELECT * 
    FROM CTE UNION 
    SELECT Business_Unit 
     ,'Margin %' 
     ,January*100.00/Total 
     ,February*100.00/Total 
     ,March*100.00/Total 
     ,Total*100.00/Total 
    FROM CTE 
    WHERE CLASS='Margin'
