Question

我已经回顾了其他类似的问题，但我的查询中没有Where条款，这让我对如何解决它感到困惑。

INSERT INTO #tmpCombined  
SELECT A.Region  
    , 'MyLocation' AS 'Location'  
    , c.Id AS 'CompID'  
    , c.Name AS 'CompName'  
    , 'Cash' AS 'Context'  
    , isnull( sum( CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END,0 )) AS 'ZeroDays0'  
    , isnull( sum( CASE WHEN T.TranAge >= 1 and CASE WHEN T.TranAge < 8 THEN 1 ELSE 0 END ), 0 ) AS '1to7Days'  
    , isnull( sum( CASE WHEN T.TranAge >=  8 and CASE WHEN T.TranAge < 16 THEN 1 ELSE 0 END ), 0 ) AS '8to15Days'  
    , isnull( sum( CASE WHEN T.TranAge >=  16 and CASE WHEN T.TranAge < 20 THEN 1 ELSE 0 END ), 0 ) AS '16to20Days'  
    , isnull( sum( CASE WHEN T.TranAge >=  20 THEN 1 ELSE 0 END ), 0 ) AS '20DaysPlus'  
    , COUNT(1) AS 'Total'  
    , A.Level as 'Level'  
    , sum(T.USDDifference) AS 'USDRevaluation'  
    from MyLocation.dbo.Company C  
    inner join #tmpCashTBResults T on T.CompanyId = C.Id  
    inner join #tmpCashAccounts A on T.CompanyId = A.CompanyId  
    group by A.Region, C.Id, C.Name, A.Level

Answer 1

T.TranAge＆gt; = 0时的情况和T.TranAge＆lt;时的情况1那么1

这应该是

 CASE 
    WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1
 ...

这是使用CASE ... WHEN构造指定复合条件的语法。

Answer 2

这一点：

THEN 1 ELSE 0 END,0 )) AS 'ZeroDays0'

应该是

THEN 1 ELSE 0 END) ,0 ) AS 'ZeroDays0'

也许？

Answer 3

你在,0错误的地方，改变这个：

isnull( sum( CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END,0 ))

为：

isnull( sum( CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END), 0)

此外，您的case语句错误，条件中不应该有另一个case。改变那些看起来像这样的人;

CASE WHEN T.TranAge >= 0 and CASE WHEN T.TranAge < 1 THEN 1 ELSE 0 END

为：

CASE WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1 ELSE 0 END

Answer 4

请对您的案件情况进行更改：

, isnull( sum( CASE WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1 ELSE 0 END ),0) AS 'ZeroDays0'

Answer 5

对于ZeroDays0列，您传递,0作为SUM函数的参数，而不是ISNULL。

Answer 6

您的查询中要解决的问题

不推荐使用单引号别名。习惯使用方括号，或者当别名很好时保留它们
当您已经使用SUM(CASE.. WHEN.. THEN 1 ELSE 0 END)时，CASE语句的本质是它永远不会为NULL，因此用ISNULL包装它是多余的。
CASE的基本结构是CASE WHEN <condition> THEN <value>。这里的<condition>可以是任何表达式，甚至是多重比较。

更正并重新格式化的查询：

  INSERT INTO #tmpCombined  
  SELECT A.Region  
       , 'MyLocation' AS Location  
       , c.Id AS CompID  
       , c.Name AS CompName  
       , 'Cash' AS Context  
       , sum( CASE WHEN T.TranAge >= 0 and T.TranAge < 1 THEN 1 ELSE 0 END) AS ZeroDays0  
       , sum( CASE WHEN T.TranAge >= 1 and T.TranAge < 8 THEN 1 ELSE 0 END) AS [1to7Days]  
       , sum( CASE WHEN T.TranAge >= 8 and T.TranAge < 16 THEN 1 ELSE 0 END) AS [8to15Days]  
       , sum( CASE WHEN T.TranAge >= 16 and T.TranAge < 20 THEN 1 ELSE 0 END) AS [16to20Days]  
       , sum( CASE WHEN T.TranAge >= 20 THEN 1 ELSE 0 END) AS [20DaysPlus]  
       , COUNT(1) AS Total  
       , A.Level as Level  
       , sum(T.USDDifference) AS USDRevaluation  
    from MyLocation.dbo.Company C  
    join #tmpCashTBResults T on T.CompanyId = C.Id  
    join #tmpCashAccounts A on T.CompanyId = A.CompanyId  
group by A.Region, C.Id, C.Name, A.Level;

在预期条件的上下文中指定的非布尔类型的表达式，在'，'附近
