mysql 获取规定时间段内的统计数据
按年统计
SELECT count(*), DATE_FORMAT(order_info.create_time, '%Y-%m-%d') AS count_by_date FROM order_info WHERE DATE_FORMAT(order_info.create_time, '%Y') = '2017' GROUP BY count_by_date ORDER BY NULL
按月统计
SELECT count(*), DATE_FORMAT(order_info.create_time, '%Y-%m-%d') AS count_by_date FROM order_info WHERE DATE_FORMAT(order_info.create_time, '%Y-%m') = '2017-04' GROUP BY count_by_date ORDER BY NULL
具体变换可以自己根据需求变更。
