MySQL数据库中SQL对日期查询相关操作

标签：nbsp   for   diff   div   submit   class   date()   时间戳   enter   

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~~~
