合併一行中不同列的計數值

Question

這是代碼和結果，我只需要顯示一行... 任何建議謝謝。

Answer 1

你可以嘗試SUM這樣

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 

Answer 2

你的問題顯得有一些錯誤，但我想你想要讓你有每個院系只有一排可以摺疊的數據。如果是這樣，你可以使用max()爲：

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
