在mysql中对时间日期操作的函数有很多,有时我们就希望直接通过sql查询出指定日期的数据了,下面小编来给大家总结一下.
使用DATE_FORMAT方法:SELECT * FROM `ler_items` WHERE DATE_FORMAT(postTime,'%Y-%m')='2013-03'
注意:日期一定要用'',否则没有效果,其它的一些关于mysql日期查找语句,代码如下:
- mysql> select date_format(DATE_SUB(CURDATE(), INTERVAL 7 DAY),’%y%m%d’);
- +———————————————————–+
- | date_format(DATE_SUB(CURDATE(), INTERVAL 7 DAY),’%y%m%d’) |
- +———————————————————–+
- | 120416 |
- +———————————————————–+
- 1 row in set (0.00 sec)
可以获取7天前的日期,使用DATE_SUB(CURDATE(), INTERVAL 7 DAY)来获得7天前的时间,用date_format 来指定输出格式.
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 *
- 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()) //Vevb.com
- 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`
- WHERE 1
- LIMIT 0 , 30
