SELECT DATE_FORMAT(LAST_DAY(CURDATE()), '%Y-%m-%d 23:59:59')
           

某個月有多少天：

SELECT DAY(LAST_DAY('2018-06-01'));

============================================================================================

今天

select * from 表名 where to_days(時間字段名) = to_days(now());      

昨天

SELECT * FROM 表名 WHERE TO_DAYS( NOW( ) ) - TO_DAYS( 時間字段名) <= 1      

近7天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(時間字段名)      

近30天

SELECT * FROM 表名 where DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(時間字段名)      

本月

SELECT * FROM 表名 WHERE DATE_FORMAT( 時間字段名, '%Y%m' ) = DATE_FORMAT( CURDATE( ) , '%Y%m' )      

上一月

SELECT * FROM 表名 WHERE PERIOD_DIFF( date_format( now( ) , '%Y%m' ) , date_format( 時間字段名, '%Y%m' ) ) =1      

查詢本季度資料

查詢上年資料

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

查詢目前這周的資料

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

查詢上周的資料
