MySQL查詢的方式很多，下面為您介紹的MySQL查詢實現的是查詢本週、上週、本月、上個月份的資料，如果您對MySQL查詢方面感興趣的話，不妨一看。

查詢當前今天的資料 
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) =date_format(now(),'%Y-%m-%d');


查詢當前這周的資料 
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())

;


查詢上週的資料
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1;


查詢當前月份的資料
select name,submittime from enterprise   where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m')


查詢距離當前現在6個月的資料
select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now()

;


查詢上個月的資料
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

預設情況下， 這個 yearweek、WEEK ( 日期 )  是 每把週日，作為一週的開始。

有的是週日開始，有的是週一開始。而工作中有的時候每週是從週六開始算的，有些資料需要按周統計，那麼那種方式比較好呢？

通過下面的研究，認為yearweek()是適合的，它返回的是 201311這樣的格式。若要把週六當做新的一週的開始，那麼就是： select yearweek(DATE_ADD(now(), INTERVAL 1 DAY)); mysql> select yearweek(DATE_ADD(now(), INTERVAL 1 DAY)); +-------------------------------------------+ | yearweek(DATE_ADD(now(), INTERVAL 1 DAY)) | +-------------------------------------------+ |                                    201311 | +-------------------------------------------+ 1 row in set mysql> select yearweek(now()); +-----------------+ | yearweek(now()) | +-----------------+ |          201310 | +-----------------+ 1 row in set mysql> 

select yearweek(now() - INTERVAL 1 DAY)    從周1開始本週計算

select yearweek('2015-02-02 11:12:00' - INTERVAL 1 DAY)

前一week的第一天：
select date_sub(curdate(),INTERVAL WEEKDAY(curdate()) + 8 DAY)

前一week的最後一天：
select date_sub(curdate(),INTERVAL WEEKDAY(curdate()) + 2 DAY)

前兩week的第一天：
select date_sub(curdate(),INTERVAL WEEKDAY(curdate()) + 15 DAY)

前兩week的最後一天：
select date_sub(curdate(),INTERVAL WEEKDAY(curdate()) + 9 DAY)
當前month的第一天：
SELECT concat(date_format(LAST_DAY(now()),’%Y-%m-’),’01′)

當前month的最後一天：
