SELECT * from 表名 where DATE_FORMAT(时间字段,"%Y-%m-%d") = DATE_ADD(输入时间,INTERVAL -1 DAY);
/** 如果需要加指定天数把-1改为指定天数即可 */
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);
/*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
select name,submittime from enterprise where date_format(submittime,‘%Y-%m‘)=date_format(DATE_SUB(curdate(), INTER VAL 1 MONTH),‘%Y-%m‘)
select * from `user` where DATE_FORMAT(pudate,‘%Y%m‘) = DATE_FORMAT(CURDATE(),‘%Y%m‘) ;
因为之前没怎么经常操作,所以留个笔记~~~
