mysql查询上月，本月，上周，本周记录的sql代码


 mysql获取上月，本月，上周，本周记录

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
本季度的第一天 ，然后你可以把字符串再转换为日期。 方法很多，包括同一个函数的别名（同义词）也很多。比如CURDATE(),CURRENT_DATE(), CURRENT_DATE, NOW 等都可以返回当天
mysql教程> select CURDATE(),ELT(QUARTER(CURDATE()),

-> year(CURDATE())*1000+1001) as firstDayofQ;

用mysql语句获取本季度的第一天
本月的第一天，
date(
concat(year(curdate()),’-',month(curdate()),’-',’1′))
本周的第一天
curdate()-
WEEKDAY(curdate())
用mysql语句获取本季度的第一天
date(
concat(year(curdate()),’-',
if(quarter(curdate())=1,1,if(quarter(curdate())=2,4,if(quarter(curdate())=3,7,10))
用mysql语句获取本季度的第一天：
优化：
date(
concat(year(curdate()),’-',elt(quarter(curdate()),1,4,7,10),’-',1))
本周的第一天
date_add(date(’2009-5-29′),INTERVAL -weekday(’2009-5-29′) day)
mysql 获取当天发布文件内容sql语句
SELECT * FROM `p8_memberdata` where regdate BETWEEN (UNIX_TIMESTAMP(NOW())-86440) AND NOW()
SELECT * FROM `p8_memberdata` WHERE DATE_FORMAT(FROM_UNIXTIME(regdate),’%Y-%m-%d’)= DATE_FORMAT(NOW(),’%Y-%m-%d’) order by uid desc

查询当天的记录
select * from hb_article_view where TO_DAYS(hb_AddTime) = TO_DAYS(NOW())
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 *
