这是我想输入的格式。对于特定的年份，我们称之为2008：

Time Completed  Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
12AM    1                                           
1AM                             2               1
2AM     1           1                   1       
3AM                                             3
4AM                 342     1                   
.                                   32          34
.                   42                          
.                                               
NEXT DAY 12AM       2                   1                   
NEXT DAY 1AM                    1                           
.                                               
.                                               

…………

DateTime Entered给了我们开始的一天，DateTime Completed给了我们完成的时间。

例如第一个。它将有一个完整的时间，14:39而对于第二个它将是5th day 15:29。第三个是2nd day 13:40

非常感谢您的建议和指导。如果您能指出我正确的方向，我将不胜感激。

SQL 或 SSRS 解决方案将是理想的。

Answer 1

您可以按小时对持续时间进行分组：

select  datediff(hour, [DateTime Entered], [DateTime Completed])
,       sum(case when month([DateTime Entered] = 1 then 1 end) as Jan
,       sum(case when month([DateTime Entered] = 2 then 1 end) as Feb
,       sum(case when month([DateTime Entered] = 3 then 1 end) as Mar
,       ...
from    YourTable
group by
        datediff(hour, [DateTime Entered], [DateTime Completed])

重新阅读，似乎我可以用第二种方式阅读你的问题。如果您想按结束时间分组（即 7 月 2 日 23:00 到 7 月 3 日 01:00 将计为 25 小时），那么您可以将开始时间转换为日期：

select  datediff(hour, cast([DateTime Entered] as date), [DateTime Completed])
,       sum(case when month([DateTime Entered] = 1 then 1 end) as Jan
,       ...
from    YourTable
group by
        datediff(hour, cast([DateTime Entered] as date), [DateTime Completed])

Answer 2

编辑包括排序：
