Question

我尝试在Tableau中重新创建一个视图作为SQL中的视图。它需要我基于月份来旋转表格，不仅要求总和金额，还需要按保证金加总，还要创建保证金％行。所需的输出是

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%

我可以根据月份进行调整，但是如何在一个数据透视表中执行两次总结以及如何包含一个percenatge行呢？

到目前为止

代码

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

不是我做过的最漂亮的SQL。但这似乎有用......

它的作用是通过生成边距线并添加总列来建立您已完成的工作使用此行和总计，我们可以计算保证金的百分比。分组SETS允许我生成多行，小计和总计，因为我知道生成的唯一额外行将具有空类，所以我能够在null时将类的名称设置为margin。

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'

SQL：包含总和和百分比的数据透视表
