1.mysql查询当天的数据

6.mysql查询上月的数据
select * from table where PERIOD_DIFF(date_format(now(),'%Y%m') , date_format(时间字段,'%Y%m')) =1
7.mysql查询本年的数据

10.mysql查询近五分钟的数据
SELECT * FROM table WHERE 时间字段 >= DATE_SUB(now(),INTERVAL 5 MINUTE)
额外知识：
NOW(),CURRENT_DATE(),SYSDATE(),CURTIME(),CURRENT_TIMESTAMP()区别
注：CURRENT_TIMESTAMP是NOW的同义词，也就是说两者是相同的。
SYSDATE函数返回的是执行到当前函数时的时间，而NOW返回的是执行SQL语句时的时间。
1 、 查看当天日期
select current_date();
2、 查看当天时间
select current_time();
3、查看当天时间日期
select current_timestamp();
4、查询当天记录
select * from 表名 where to_days(时间字段名) = to_days(now());
5、查询昨天记录
SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) – TO_DAYS( 时间字段名) <= 1
6、查询7天的记录
SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名)
7、查询近30天的记录
SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(时间字段名)
8、查询本月的记录
SELECT * FROM 表名 WHERE DATE_FORMAT( 时间字段名, ‘%Y%m’ ) = DATE_FORMAT( CURDATE( ) , ‘%Y%m’ )
9、查询上一月的记录
SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , ‘%Y%m’ ) , date_format( 时间字段名, ‘%Y%m’ ) ) =1
10、查询本季度数据
select * from 表名 where QUARTER(create_date)=QUARTER(now());
11、查询上季度数据
select * from 表名 where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));
12、查询本年数据
select * from 表名 where YEAR(create_date)=YEAR(NOW());
13、查询上年数据
select * from 表名 where year(create_date)=year(date_sub(now(),interval 1 year));
14、查询当前这周的数据
SELECT * FROM 表名 WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());
15、查询上周的数据
SELECT * FROM 表名 WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;
16、查询当前月份的数据
select * from 表名 where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')
17、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();
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
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());
#查询上年数据
select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));
查询当前这周的数据
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;
查询当前月份的数据
select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')
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();
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 *

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
where date(regdate) = curdate();
select * from test where year(regdate)=year(now()) and month(regdate)=month(now()) and day(regdate)=day(now())
SELECT date( c_instime ) ,curdate( )
FROM `t_score`
