SQL需要根据小时合并两列

Question

我有以下查询，我需要根据hour_interval合并两列Total_here和Total_there。我已经设法通过使用UNION运行两个查询，但基本上每小时创建两行（一行为'Total new'，一行为'Total_done'）。当我尝试将这两行转换为两列时，我遇到了问题。

SELECT 
    hour_interval as hours 
FROM
    SELECT  
        DATEPART(hour, person) as hour_interval,  
        COUNT(person) AS Total_person 
    FROM 
        (SELECT
             CASE
                WHEN DATEPART(hour, x.person) > 12 
                   THEN DATEADD (MINUTE, -1 * DATEPART(minute, x.person) - 1, x.person)
                WHEN DATEPART(hour, x.person) < 4  
                   THEN DATEADD (MINUTE, 55, x.person)
                ELSE x.person 
             END AS person
         FROM 
             new_table) f2

        UNION

        SELECT  DATEPART( hour , done_person ) as hour_interval_1, COUNT(done_person) AS Total_done_person FROM 
        (
            SELECT
            case when DATEPART ( hour , x.done_person ) > 12 then DATEADD (MINUTE,-1 * DATEPART ( minute , x.done_person )-1,x.done_person)
            when DATEPART ( hour , x.done_person ) < 4  then DATEADD (MINUTE, 55,x.done_person)
            else x.done_person end as done_person
            FROM done_table
        ) f3

    group by hours
