有時(shí)我們面要統(tǒng)計(jì)一下數(shù)據(jù)庫中指定日期的數(shù)據(jù),如常用的,今天,昨天,明天,本周、上周、本月、上個(gè)月份的數(shù)據(jù),除了我們可以使用strtotime來算還可以參考下面方法.

今天:select * from 表名 where to_days(時(shí)間字段名)=to_days(now()); 

昨天:SELECT * FROM `表名` where TO_DAYS(NOW()) – TO_DAYS(時(shí)間字段名) = 1;

/*DATEDIFF(now() , FROM_UNIXTIME(`時(shí)間字段名`)) = 1; //時(shí)間字段 存儲(chǔ)類型為時(shí)間戳*/

7天:SELECT * FROM `表名` where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(時(shí)間字段名);

/*DATEDIFF(now() , FROM_UNIXTIME(`時(shí)間字段名`)) = 7; //時(shí)間字段 存儲(chǔ)類型為時(shí)間戳*/

近30天:SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(時(shí)間字段名);

本月:SELECT * FROM 表名 WHERE DATE_FORMAT(時(shí)間字段名, '%Y%m' = DATE_FORMAT(CURDATE(), '%Y%m'; 

查詢當(dāng)前這周的數(shù)據(jù):SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now()); 

查詢上周的數(shù)據(jù):SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1; 

查詢當(dāng)前月份的數(shù)據(jù):select name,submittime from enterprise   where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m') 

查詢距離當(dāng)前現(xiàn)在6個(gè)月的數(shù)據(jù):select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now(); 

查詢上個(gè)月的數(shù)據(jù),代碼如下:

1. select name,submittime from enterprise   where date_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m')  
2.     
3. select * from `user` where DATE_FORMAT(pudate,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m') ;  
4.    
5. select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = WEEKOFYEAR(now())  
6.    
7. select *   
8. from user  
9. where MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now())  
10.    
11. select *   
12. from [user]   
13. where YEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = YEAR(now())  
14. and MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()) --Vevb.com 
15.    
16. select *   
17. from [user]   
18. where pudate between  

上月最后一天 and 下月第一天.
