mysql 查询 一天内 一周内 一年的数据

select * from wap_content where week(created_at) = week(now)  如果你要严格要求是某一年的，那可以这样  查询一天：  select * from table where to_days(column_time) = to_days(now());  select * from table where date(column_time) = curdate();  查询一周：  select * from table where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(column_time);  查询一个月：  select * from table where DATE_SUB(CURDATE(), INTERVAL INTERVAL 1 MONTH) <= date(column_time);
