MySQL 的 YEARWEEK 是獲取年份和週數的一個函數，函數形式爲 YEARWEEK(date[,mode])

例如 2010-3-14 ，禮拜天

SELECT YEARWEEK('2010-3-14') 返回 11
SELECT YEARWEEK('2010-3-14',1) 返回 10

其中第二個參數是 mode ，具體指的意思以下：

Mode	First day of week	Range	Week 1 is the first week …
0	Sunday	0-53	with a Sunday in this year
1	Monday	0-53	with more than 3 days this year
2	Sunday	1-53	with a Sunday in this year
3	Monday	1-53	with more than 3 days this year
4	Sunday	0-53	with more than 3 days this year
5	Monday	0-53	with a Monday in this year
6	Sunday	1-53	with more than 3 days this year
7	Monday	1-53	with a Monday in this year

查詢當前這周的數據

           SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now()); 
         

查詢上週的數據

           SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1; 
         

查詢當前月份的數據

           select name,submittime from enterprise   where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m') 
         

查詢距離當前如今6個月的數據

           select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now(); 
         

查詢上個月的數據

           select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m'); 
         
           select * from `user` where DATE_FORMAT(pudate,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m') ; 
         
           select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = WEEKOFYEAR(now()); 
         
           select * from user where MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()); 
         
           select * from [user] where YEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = YEAR(now()) and MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()); 
         
           select * from [user] where pudate between 上月最後一天 and 下月第一天;
