查询每个小时的数据量

   SELECT HOUR(e.user_scheduling_in_time) as Hour,count(*) as Count 

    FROM tb_user_scheduling e
		
    WHERE e.user_scheduling_in_time  between '2020-07-16 00:00:00'  and '2020-07-16 23:59:59' 

    GROUP BY HOUR(e.user_scheduling_in_time) ORDER BY Hour(e.user_scheduling_in_time);

由上图可知查询正确。
