 mysql日期与时间查询语句：查询当年、查询本年、查询当月、查询本周

当天  select * from 表名 where to_days(时间字段名) = to_days(now());

昨天  select * from 表名 where to_days( now( ) ) – to_days( 时间字段名) <= 1

一周  select * from 表名 where date_sub(curdate(), interval 7 day) <= date(时间字段名)

近30天 select * from 表名 where date_sub(curdate(), interval 30 day) <= date(时间字段名)

本月   select * from 表名 where date_format( 时间字段名, ‘%y%m’ ) = date_format( curdate( ) , ‘%y%m’ )

上一月  select * from 表名 where period_diff( date_format( now( ) , ‘%y%m’ ) , date_format( 时间字段名, ‘%y%m’ ) ) =1
