这是我希望将其放入的格式。对于特定年份，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为我们提供了开始日期，DateTime Completed为我们提供了完成时间。
例如第一个。它的完成时间为14:39，而第二个时间则为5th day 15:29。第三个是2nd day 13:40
非常感谢你的建议和指导。如果你能指出我正确的方向，我将非常感激。
SQL或SSRS解决方案是理想的。

您可以按小时分组持续时间：
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。如果您想在结束时间分组（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投射到目前为止：
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])
