本文介绍了mysql查询今天、昨天、7天、近30天、本月、上一月数据的方法，参考代码已给出：

　　1.今天

　　select * from 表名 where to_days(时间字段名) = to_days(now());

　　2.昨天

　　SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 时间字段名) <= 1

　　3.7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

　　#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));

　　8.查询当前这周的数据

　　参考代码如下所示：

　　SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now());

　　8.查询上周的数据

　　参考代码如下所示：

　　SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;

　　10.查询当前月份的数据

　　参考代码如下所示：

　　select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')

　　11.查询距离当前现在6个月的数据

　　参考代码如下所示：

　　select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();

　　12.查询上个月的数据

　　参考代码如下所示：

　　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
