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);
查询某几天：
关键字between 等同于 datetime >= 2010-02-02 00:00:00' and datetime <=  '2010-02-15 00:00:00';
select * from table where datetime between '2010-02-02 00:00:00' and '2010-02-15 00:00:00';
