MySQL中获取天、周、⽉等数据
1.今天
select * from 表名 where to_days(时间字段名) = to_days(now());
mysql中select2.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.近30天
SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(时间字段名)
5.本⽉
SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )
6.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
7.查询本季度数据
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());
8.查询上季度数据
select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));
9.查询本年数据
select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW());
10.查询上年数据
select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));
11.查询当前这周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());
12.查询上周的数据
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;
13.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
14.查询当前⽉份的数据
select name,submittime from enterprise  where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')
15.查询距离当前现在6个⽉的数据
select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();
``` select curdate(); --获取当前⽇期 select last_day(curdate()); --获取当⽉最后⼀天。 select DATE_AD
D(curdate(),interval -day(curdate())+1 day); --获取本⽉第⼀天 select date_add(curdate()-day(curdate())+1,interval 1 month); -- 获取下个⽉的第⼀天 select
DATEDIFF(date_add(curdate()-day(curdate())+1,interval 1 month ),DATE_ADD(curdate(),interval -day(curdate())+1 day)) from dual; --获取当前⽉的天数
<hr>
<hr>
查询本周所有的数据（本周第⼀天是周⼀）
SELECT * FROM task WHERE YEARWEEK(date_format(时间字段,'%Y-%m-%d'),1) = YEARWEEK(now(),1)；查询本周所有的数据（本周第⼀天是周⽇）
SELECT * FROM task WHERE YEARWEEK(date_format(时间字段,'%Y-%m-%d')) = YEARWEEK(now());
