SQL子查询返回的两行的总和

Question

我创建了以下SQL查询

SELECT ae.[intEntitlementID] 
      ,SUM(decIncrease) - SUM([decDecrease]) as quantity
                ,(SELECT SUM([decCredit]) - SUM([decDebit]) as value
                FROM [tblMonetaryValueEvent]
                where [intEntitlementID] = ae.intEntitlementID
                and intSchemeYear <= @intSchemeYear
                group by intEntitlementID) AS VALUE
    ,(SUM(decIncrease) - SUM([decDecrease])) *
                (SELECT SUM([decCredit]) - SUM([decDebit]) as value
                FROM [tblMonetaryValueEvent]
                where [intEntitlementID] = ae.intEntitlementID
                and intSchemeYear <= @intSchemeYear
                group by intEntitlementID) AS TOTAL



  FROM [tblAllocationEvent] ae

  where ae.intBusinessID = @intBusinessID
  and ae.intSchemeYear <= @intSchemeYear
  group by ae.intEntitlementID

  HAVING SUM(decIncrease) - SUM([decDecrease]) > 0

哪个返回以下内容

我现在需要在TOTAL列中找到两行的总和。

我希望输出以下数据。 73046.908322 + 1150.946103

有人对如何求和子查询返回的两个结果有任何提示吗？

谢谢

Answer 1

使用ROLLUP

SELECT i, count(*) as c, sum(i) as s
FROM TEST
WHERE i<5
GROUP BY ROLLUP(i)

给予：

i   c   s
1   1   1
2   1   2
3   1   3
4   1   4
NULL    4   10

Answer 2

正如@mkRabbani所说，您可以改善查询条件... 我想下一个可能是 -更具可读性 -表现更好（但我无法测试，因为没有数据）

所以，未经测试！：

WITH sums AS (
  SELECT 
    ae.[intEntitlementID]
    ,SUM(decIncrease)-SUM(decDecrease) AS quantity 
    ,SUM(decCredit)-SUM(decDebit) As value
  FROM [tblAllocationEvent] ae
  INNER JOIN [tblMonetaryValueEvent] ON [intEntitlementID] = ae.intEntitlementID
                                  and intSchemeYear <= ae.intSchemeYear
  where ae.intBusinessID = @intBusinessID
  and ae.intSchemeYear <= @intSchemeYear
  group by ae.intEntitlementID
)
SELECT
  intEntitlementID
  ,quantity
  ,value
  ,quantity * value as Total
FROM sums
