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) <= 17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 userwhere 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 1LIMIT 0 , 30注:关于MySQL日期查询语句分析的内容就先介绍到这里,更多相关文章的可以留意
