MySQL查询的方式很多，下面为您介绍的MySQL查询实现的是查询本周、上周、本月、上个月份的数据，如果您对MySQL查询方面感兴趣的话，不妨一看。
　　
　　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

　　java 获取时间戳 2010-11-11 09:18:50| 分类： java | 标签： |字号大中小 订阅 .
　　
　　 Date date = new Date();
　　 long time = date.getTime();
　　
　　//mysq 时间戳只有10位 要做处理
　　 String dateline = time + "";
　　 dateline = dateline.substring(0, 10);
