查询每天的数据

 SELECT COUNT(1) AS total, DATE_FORMAT(created_time,'%Y-%m-%d') AS days FROM task_execution GROUP BY days desc;

查询每周的数据

SELECT COUNT(1) AS total, WEEK(created_time) AS weeks FROM task_execution GROUP BY weeks desc;

查询每月的数据

SELECT COUNT(1) AS total, MONTH(created_time) AS months FROM task_execution GROUP BY months desc;

查询每年的数据

注意：
DATE_ADD(createTime,INTERVAL 1 DAY) 得到指定日期后一天的日期/把1改为任意数字就可以得到后N天的日期
DATE_SUB(createTime,INTERVAL 1 DAY) 得到指定日期前一天的日期/把1改为任意数字就可以得到前N天的日期
