mysql限制sql查詢時間的方法：

今天

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

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

查詢本季資料

select * from ht_invoice_information where QUARTER(create_date)=QUARTER(now());

查詢上季資料

select * from ht_invoice_information where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

查詢本年資料

select * from ht_invoice_information where YEAR(create_date)=YEAR(NOW());

查詢上年度資料

select * from ht_invoice_information where year(create_date)=year(date_sub(now(),interval 1 year));

查詢目前這週的資料

SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,’%Y-%m-%d’)) = YEARWEEK(now());

查詢上週的資料

SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,’%Y-%m-%d’)) = YEARWEEK(now())-1;

查詢上個月的資料

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

查詢目前月份的資料

select name,submittime from enterprise where date_format(submittime,’%Y-%m’)=date_format(now(),’%Y-%m’)
