昨天
select * from 表名 where to_days( now( ) ) - to_days( 时间字段名) <= 1
近7天
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
查询本季度数据
select * from ht_invoice_information where quarter(create_date)=quarter(now());
查询上季度数据
select * from ht_invoice_information where quarter(create_date)=quarter(date_sub(now(),interval 1 quarter));
查询本年数据
select * from ht_invoice_information where year(create_date)=year(now());

select name,submittime from enterprise where yearweek(date_format(submittime,’%y-%m-%d’)) = yearweek(now());
查询上周的数据
select name,submittime from enterprise where yearweek(date_format(submittime,’%y-%m-%d’)) = yearweek(now())-1;
查询上个月的数据
select name,submittime from enterprise where date_format(submittime,’%y-%m’)=date_format(date_sub(curdate(), interval 1 month),’%y-%m’)select * from user where date_format(pudate,’%y%m’) = date_format(curdate(),’%y%m’) ;select * from user where weekofyear(from_unixtime(pudate,’%y-%m-%d’)) = weekofyear(now())select * from user where month(from_unixtime(pudate,’%y-%m-%d’)) = month(now())select * from user where year(from_unixtime(pudate,’%y-%m-%d’)) = year(now()) and month(from_unixtime(pudate,’%y-%m-%d’)) = month(now())select * from user where pudate between 上月最后一天 and 下月第一天
