FROM   (SELECT cast(Notes as char) AS [Adres], CaseActionDefinitionId AS [Info1], NULL AS [Numer], NULL as      [Info2], NULL AS [Mail], NULL as [Info3], NULL AS [Powód], CaseDetailId
        FROM   CaseActionHistory
        WHERE  CaseActionDefinitionId = 68
    UNION ALL
    SELECT NULL, NULL, cast(Info as char), CaseActionDefinitionId, NULL, NULL, NULL, CaseDetailId
        FROM   CaseActionHistory
        WHERE  CaseActionDefinitionId IN (54, 55, 56, 58,
                                      59, 60, 61, 62, 63)
    UNION ALL
        SELECT NULL, NULL, NULL, NULL, cast(Notes as char), CaseActionDefinitionId, NULL, CaseDetailId
        FROM   CaseActionHistory
        WHERE  CaseActionDefinitionId = 66
    UNION ALL
        SELECT NULL, NULL, NULL, NULL, NULL, NULL, cast(Description as char(100)), CaseDetailId
        FROM   CaseActionDefinition JOIN CaseActionHistory AS C ON DefinitionId = C.CaseActionDefinitionId
        WHERE  DefinitionId BETWEEN 70 AND 78) AS x
       INNER JOIN CaseDetails AS C
               ON x.CaseDetailId = C.CaseDetailsId
       INNER JOIN CaseActionHistory AS CA
               ON C.CaseDetailsId = CA.CaseDetailId
WHERE  C.ClientId = 11
GROUP  BY C.ClientCaseNumber

我遇到了sum（case）的问题。每当删除一个CaseActionHistory记录（CA.IsDeleted ='True'）时，值都会乘以x2，有时甚至更多，没有任何理由。只运行查询的某个部分：

SELECT
C.ClientCaseNumber
,Sum(CASE
        WHEN CA.CaseActionDefinitionId IN (28, 29, 30) THEN 1
        ELSE 0
    END) AS [Wezwania]
from
CaseActionHistory as CA
join CaseDetails as C on CA.CaseDetailId = C.CaseDetailsId
where C.ClientId = '11'
group by CD.ClientCaseNumber

完美地记录记录而没有任何问题。

我还需要添加一个参数

....AS x
           INNER JOIN CaseDetails AS C
                   ON x.CaseDetailId = C.CaseDetailsId
           INNER JOIN CaseActionHistory AS CA
                   ON C.CaseDetailsId = CA.CaseDetailId
    WHERE  C.ClientId = 11 and CA.IsDeleted <> 'True'
    GROUP  BY C.ClientCaseNumber

然而，这会使所有计数和所有总和都相等。但是有趣的是：

AS x
           INNER JOIN CaseDetails AS C
                   ON x.CaseDetailId = C.CaseDetailsId
           INNER JOIN CaseActionHistory AS CA
                   ON C.CaseDetailsId = CA.CaseDetailId
    WHERE  C.ClientId = 11 and CA.IsDeleted = 'True'
    GROUP  BY C.ClientCaseNumber

完美运作，并将已删除的代码汇总。

IsDeleted可以有三个值：NULL / True / False，默认为NULL。将代码设置为已删除后为True;恢复代码后返回false。

Answer 1

尝试更改

CA.IsDeleted <> 'True'

到

(CA.IsDeleted <> 'True' OR CA.IsDeleted IS NULL)

Answer 2

试试这个

(isnull(CA.IsDeleted,'')='' or CA.IsDeleted <> 'True')

满足条件时，值乘以
