合并一行中不同列中的计数值

Question

这是代码和结果，我只需要显示一行... 任何建议谢谢。

Answer 1

您的问题似乎有些错误，但我认为您要折叠数据，因此每个学院和部门只有一行。如果是这样，您可以使用max()，如下所示：

select
   College
  ,Department
  ,max(January) as January
  ,max(February) as February
  ,max(March) as March
from your_query_in_question     -- put your existing query here
group by
   College
  ,Department

Answer 2

您可以尝试这样的SUM

SELECT  college,
        department,
        COUNT(department) as departmentCount,
        SUM(CASE when datepart(month,[date]) = 1 then 1 else 0 END) as [January],
        SUM(CASE when datepart(month,[date]) = 2 then 1 else 0 END) as [February]
From rpt_school
GROUP BY college,department
