mysql查询日期内的所有日期代码

一、MYSQL查询最近的三个月份的简便方法:

select date_format(curdate(),\'%Y-%m\') from dual 
union
select date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),\'%Y-%m\') from dual 
union 
select date_format(DATE_SUB(curdate(), INTERVAL 2 MONTH),\'%Y-%m\')  from dual 



二、sql查询两个日期内的所有日期

select * from (select @num:=@num+1,date_format(adddate(\'2018-03-11\', INTERVAL @num DAY),\'%Y-%m-%d\') as date
from user_attendance,(select @num:=0) t where adddate(\'2018-03-11\', INTERVAL @num DAY) <= date_format(\'2018-03-15\',\'%Y-%m-%d\')
order by date
)a

注意有个前提:必须要有一个表，它的数据条数大到足够支撑你要查询的天数
