MySQL 按时间查询

 

　　1.今天

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

　　2.昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 时间字段名) <= 1

　　3.近7天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名)

　　4.当月

SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, \'%Y%m\' ) = DATE_FORMAT( CURDATE( ) , \'%Y%m\' )

　　5.上月

SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , \'%Y%m\' ) , date_format( 时间字段名, \'%Y%m\' ) ) =1

　　6.本季度

select * from `表名` where QUARTER(时间字段)=QUARTER(now());

　　7.上季度

select * from `表名` where QUARTER(时间字段)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

　　8.今年

select * from `表名` where YEAR(时间字段)=YEAR(NOW());

　　9.去年

select * from `表名` where year(时间字段)=year(date_sub(now(),interval 1 year));

　　10.本周

select * from 表名 WHERE YEARWEEK(date_format(时间字段,\'%Y-%m-%d\')) = YEARWEEK(now());

　　11.上周

select * from 表名 WHERE YEARWEEK(date_format(字段名,\'%Y-%m-%d\')) = YEARWEEK(now())-1;

　　12.近6个月

select * from 表名 where 字段名 between date_sub(now(),interval 6 month) and now();
