当 BLA （最后一个字段）大于 40 时，我希望它只是将所有值相加并打印41为最后一行：

如您所见，最后一行是所有内容的总和，41甚至更多。

这是我的查询：

select 
sum(case when datepart(month,[datetime entered]) = 1 then 1 end) as Jan,
sum(case when datepart(month,[datetime entered]) = 2 then 1 end) as Feb,
sum(case when datepart(month,[datetime entered]) = 3 then 1 end) as Mar,
sum(case when datepart(month,[datetime entered]) = 4 then 1 end) as Apr,
sum(case when datepart(month,[datetime entered]) = 5 then 1 end) as May,
sum(case when datepart(month,[datetime entered]) = 6 then 1 end) as Jun,
sum(case when datepart(month,[datetime entered]) = 7 then 1 end) as Jul,
sum(case when datepart(month,[datetime entered]) = 8 then 1 end) as Aug,
sum(case when datepart(month,[datetime entered]) = 9 then 1 end) as Sep,
sum(case when datepart(month,[datetime entered]) = 10 then 1 end) as Oct,
sum(case when datepart(month,[datetime entered]) = 11 then 1 end) as Nov,
sum(case when datepart(month,[datetime entered]) = 12 then 1 end) as Dec,
DATEPART(yyyy,[datetime entered]) as [Year],
 bla= CASE WHEN datediff(d, CAST([datetime entered] as DATE), CAST([datetime completed] as DATE))*24 + 
 CONVERT(CHAR(2),[datetime completed],108)
 >41 THEN 41 ELSE datediff(d, CAST([datetime entered] as DATE), CAST([datetime completed] as DATE))*24 + 
 CONVERT(CHAR(2),[datetime completed],108)  END


from [TurnAround]

where DATEPART(yyyy,[datetime entered])=2011

group by 

datediff(d, CAST([datetime entered] as DATE), CAST([datetime completed] as DATE))*24 + 
 CONVERT(CHAR(2),[datetime completed],108),

 DATEPART(yyyy,[datetime entered])

 order by bla

我如何获得第二个示例中显示的结果，其中过去的所有内容都41被求和？

非常感谢您的指导和帮助！！

我建议您BLA在考虑该条件的情况下进行计算。但是，另一种方法是将当前查询用作派生表并使用CASE：

SELECT  SUM(Jan) Jan,
        SUM(Feb) Feb,
        SUM(Mar) Mar,
        SUM(Apr) Apr,
        SUM(May) May,
        SUM(Jun) Jun,
        SUM(Jul) Jul,
        SUM(Aug) Aug,
        SUM(Sep) Sep,
        SUM(Oct) Oct,
        SUM(Nov) Nov,
        SUM(Dec) Dec,
        CASE WHEN Bla >= 41 THEN 41 ELSE Bla END Bla
FROM (Your current query here) DT
GROUP BY CASE WHEN Bla >= 41 THEN 41 ELSE Bla END;

或 CTE：

;WITH CTE AS 
(
    Your current query here
)
SELECT  SUM(Jan) Jan,
        SUM(Feb) Feb,
        SUM(Mar) Mar,
        SUM(Apr) Apr,
        SUM(May) May,
        SUM(Jun) Jun,
        SUM(Jul) Jul,
        SUM(Aug) Aug,
        SUM(Sep) Sep,
        SUM(Oct) Oct,
        SUM(Nov) Nov,
        SUM(Dec) Dec,
        CASE WHEN Bla >= 41 THEN 41 ELSE Bla END Bla
FROM CTE
GROUP BY CASE WHEN Bla >= 41 THEN 41 ELSE Bla END;

我会使用一个通用的表表达式，如下所示，虽然我不完全确定 bla 代表什么；我假设它从进入到完成的小时数：

WITH cte AS (SELECT 
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 1 THEN 1 ELSE 0 END AS Jan,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 2 THEN 1 ELSE 0 END AS Feb,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 3 THEN 1 ELSE 0 END AS Mar,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 4 THEN 1 ELSE 0 END AS Apr,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 5 THEN 1 ELSE 0 END AS May,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 6 THEN 1 ELSE 0 END AS Jun,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 7 THEN 1 ELSE 0 END AS Jul,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 8 THEN 1 ELSE 0 END AS Aug,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 9 THEN 1 ELSE 0 END AS Sep,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 10 THEN 1 ELSE 0 END AS Oct,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 11 THEN 1 ELSE 0 END AS Nov,
    CASE WHEN DATEPART(MONTH, [datetime entered]) = 12 THEN 1 ELSE 0 END AS Dec,
    DATEPART(yyyy, [datetime entered]) AS [Year],
    FLOOR(CAST([datetime completed] AS FLOAT) - CAST([datetime entered] AS FLOAT) * 24) AS bla
)
SELECT SUM(Jan) AS Jan, SUM(Feb) AS Feb, SUM(Mar) AS Mar, SUM(Apr) AS Apr, SUM(May) AS May, SUM(Jun) AS Jun, 
    SUM(Jul) AS Jul, SUM(Aug) AS Aug, SUM(Sep) AS Sep, SUM(Oct) AS Oct, SUM(Nov) AS Nov, SUM(Dec) AS Dec,
    CASE WHEN bla > 41 THEN 41 ELSE bla END AS bla
FROM cte
GROUP BY CASE WHEN bla > 41 THEN 41 ELSE bla END AS bla
ORDER BY CASE WHEN bla > 41 THEN 41 ELSE bla END AS bla
