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 1 MONTH) <= date(column_time);
查询指定天数
select * from table where DATE_SUB(CURDATE(), INTERVAL 2 DAY) <= date(column_time);
