有时我们面要统计一下数据库中指定日期的数据,如常用的,今天,昨天,明天,本周、上周、本月、上个月份的数据,除了我们可以使用strtotime来算还可以参考下面方法.
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;
/*DATEDIFF(now() , FROM_UNIXTIME(`时间字段名`)) = 1; //时间字段 存储类型为时间戳*/
7天:SELECT * FROM `表名` where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(时间字段名);
/*DATEDIFF(now() , FROM_UNIXTIME(`时间字段名`)) = 7; //时间字段 存储类型为时间戳*/
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';
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,代码如下:
- selectname,submittimefromenterprisewheredate_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(),INTERVAL1MONTH),'%Y-%m')
- select*from`user`whereDATE_FORMAT(pudate,'%Y%m')=DATE_FORMAT(CURDATE(),'%Y%m');
- select*fromuserwhereWEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d'))=WEEKOFYEAR(now())
- select*
- fromuser
- whereMONTH(FROM_UNIXTIME(pudate,'%y-%m-%d'))=MONTH(now())
- select*
- from[user]
- whereYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d'))=YEAR(now())
- andMONTH(FROM_UNIXTIME(pudate,'%y-%m-%d'))=MONTH(now())--phpfensi.com
- select*
- from[user]
- wherepudatebetween
上月最后一天and 下月第一天.
