SQL减去指定天数

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 */

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;

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') ;
