Question

在以下两个SELECT语句中，我想比较这两个语句的输出，以获得金额不匹配的IDs。

第一个语句中的GROUP BY和SUM似乎使事情变得复杂：

SELECT CreditAHID,
SUM(Debit) as CCDebit,
SUM(Credit) as CCCredit,
FROM FS_2015_June.dbo.CCs
GROUP BY CreditAHID

SELECT ID as CreditAHID,
JuneDebit as AHDebit,
JuneCredit as AHCredit,
FROM FS_2015_2016.dbo.AHs

有没有办法将它们组合成这样的东西？

SELECT ID ... WHERE (CCDebit != AHDebit) OR (CCCredit != AHCredit)

Answer 1

您可以尝试使用CTE：

WITH cte as (
SELECT CreditAHID,
SUM(Debit) as CCDebit,
SUM(Credit) as CCCredit,
FROM FS_2015_June.dbo.CCs
GROUP BY CreditAHID
), cte2 as (
SELECT ID as CreditAHID,
JuneDebit as AHDebit,
JuneCredit as AHCredit,
FROM FS_2015_2016.dbo.AHs)

SELECT * FROM cte
UNION
SELECT * FROM cte2
WHERE CCDebit <> AHDebit and CCCredit <> AHCredit

Answer 2

请尝试以下查询：

SELECT
    ResultSet1.*
    , ResultSet2.*
FROM (
    SELECT CreditAHID
        ,SUM(Debit) AS CCDebit
        ,SUM(Credit) AS CCCredit
    FROM FS_2015_June.dbo.CCs
    GROUP BY CreditAHID
    ) ResultSet1
INNER JOIN (
    SELECT ID AS CreditAHID
        ,JuneDebit AS AHDebit
        ,JuneCredit AS AHCredit
    FROM FS_2015_2016.dbo.AHs
    ) ResultSet2 ON ResultSet1.CreditAHID = ResultSet2.CreditAHID
WHERE ResultSet1.CCDebit <> ResultSet2.AHDebit
    AND ResultSet1.CCCredit <> ResultSet2.AHCredit

此查询将返回两个结果的组合，其中CreditAHID在两个结果中匹配，并且CCDebit和CCCredit分别不等于AHDebit和AHCredit。

Answer 3

您可以简单地写为：

select T1.CreditAHID as [CCs], T2.CreditAHID as [AHs]
from (
SELECT CreditAHID,
SUM(Debit) as CCDebit,
SUM(Credit) as CCCredit,
FROM FS_2015_June.dbo.CCs
GROUP BY CreditAHID) T1
full Join (
SELECT ID as CreditAHID,
JuneDebit as AHDebit,
JuneCredit as AHCredit,
FROM FS_2015_2016.dbo.AHs) T2 
on T1.CreditAHID = T2.CreditAHID
where T1.CCDebit <> AHDebit 
and T1.CCCredit <> T2.AHCredit

Answer 4

您可以像这样使用EXCEPT：

SELECT CreditAHID,
SUM(Debit) as CCDebit,
SUM(Credit) as CCCredit,
FROM FS_2015_June.dbo.CCs
GROUP BY CreditAHID
EXCEPT
SELECT ID as CreditAHID,
JuneDebit as AHDebit,
JuneCredit as AHCredit,
FROM FS_2015_2016.dbo.AHs

注意，EXCEPT返回左输入查询中不是由右输入查询输出的不同行。因此，如果第二个查询包含更多行，则应首先引用它。

Answer 5

您可以尝试使用旧的不存在和这样的：

SELECT CreditAHID, SUM(Debit) as CCDebit, SUM(Credit) as CCCredit
   FROM FS_2015_June.dbo.CCs c
GROUP BY CreditAHID
having not exists 
       (SELECT 1
          FROM FS_2015_2016.dbo.AHs
         where ID = c.CreditAHID and 
        (Sum(c.Debit) = JuneDebit or Sum(c.Credit) = JuneCredit))
