Question

我有两个总和查询

SUM(
    CASE 
        WHEN re.ReApType = 'Allocation' AND re.ReAppType = 'E' AND re.YearID = '2015'
            THEN re.ReCapitalAmount + re.ReRevenueAmount
        ELSE
            0 
    END
) AS RevisedAllocationExcess,
SUM(
    CASE 
        WHEN re.ReApType = 'Allocation' AND re.ReAppType = 'S' AND re.YearID = '2015' 
            THEN re.ReCapitalAmount + re.ReRevenueAmount
        ELSE
            0 
    END
) AS RevisedAllocationSurrender

我想总结这两个问题。请告诉我如何总结它们并在第三栏中显示重新开始。 感谢

Answer 1

要获取两列的SUM，请修改CASE表达式：

SUM(
    CASE 
        WHEN re.ReApType = 'Allocation' AND re.ReAppType IN('E','S') AND re.YearID = '2015' 
            THEN re.ReCapitalAmount + re.ReRevenueAmount
        ELSE
            0 
    END
) 

Answer 2

将该部分代码放入子查询中：

select
  t.RevisedAllocationExcess,
  t.RevisedAllocationSurrender,
  t.RevisedAllocationExcess + t.RevisedAllocationSurrender as RevisedTotal
from
(
  select
    ...
    SUM(...) as RevisedAllocationExcess,
    SIM(...) as RevisedAllocationSurrender
) t

或CTE：

;with cteReviseTotals as
(
  select
    ...
    SUM(...) as RevisedAllocationExcess,
    SIM(...) as RevisedAllocationSurrender
)
select
  t.RevisedAllocationExcess,
  t.RevisedAllocationSurrender,
  t.RevisedAllocationExcess + t.RevisedAllocationSurrender as RevisedTotal
from cteReviseTotals t

Answer 3

试试这个

SUM(
    CASE 
        WHEN re.ReApType = 'Allocation' AND re.ReAppType = 'E' AND re.YearID = '2015'
            THEN re.ReCapitalAmount + re.ReRevenueAmount
        ELSE
            0 
    END
) AS RevisedAllocationExcess,
SUM(
    CASE 
        WHEN re.ReApType = 'Allocation' AND re.ReAppType = 'S' AND re.YearID = '2015' 
            THEN re.ReCapitalAmount + re.ReRevenueAmount
        ELSE
            0 
    END
) AS RevisedAllocationSurrender,
RevisedAllocationExcess+RevisedAllocationSurrender RevisedSum

希望这会有所帮助......
