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) <= 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()) 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 。
