今天

select * from 表名 where to_days(時間欄位名) = to_days(now());

昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 時間欄位名) <= 1

近7天

SELECT * FROM 表名 where DATE_SUB(CURDATE(),INTERVAL 7 DAY) <= date(時間欄位名)

近30天

SELECT * FROM 表名 where DATE_SUB(CURDATE(),INTERVAL 30 DAY) <= date(時間欄位名)

本月

SELECT * FROM 表名 WHERE DATE_FORMAT( 時間欄位名,'%Y%m' ) = DATE_FORMAT( CURDATE( ),'%Y%m' )

上一月

SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ),'%Y%m' ),date_format( 時間欄位名,'%Y%m' ) ) =1

查詢本季度資料

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());

查詢上季度資料

select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

查詢本年資料

select * from `ht_invoice_information` where YEAR(create_date)=YEAR(NOW());

查詢上年資料

select * from `ht_invoice_information` where year(create_date)=year(date_sub(now(),interval 1 year));

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,'%Y-%m-%d')) = YEARWEEK(now())-1;

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 

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();

PS:下面看下mysql如何查詢當天資訊？

原來不是太熟悉SQL查詢語句，什麼都是用到了再去查去找，還好網路提供給我們很多支援。今天又用到了一個語句，一時間真想不出怎麼解決，到網上看了看，感覺就有一個，怎麼那麼簡單啊。需要積累的東西真是太多了。

今天就把我這個簡單的問題記錄下來吧!算是一個積累：

mysql查詢當天的所有資訊：

select * from test where year(regdate)=year(now()) and month(regdate)=month(now()) and day(regdate)=day(now())

這個有一些繁瑣，還有簡單的寫法：

select * from table where date(regdate) = curdate();

date()函式獲取日期部分,扔掉時間部分，然後與當前日期比較即可
