MySql分层查询，如何从1到n获取序列

Question

有没有办法让MySQL查询得到与Oracle的

相同的结果

 WITH t(n) AS 
(
    SELECT 1
    FROM DUAL
    UNION ALL
    SELECT n+1 FROM t WHERE n < 5
)
SELECT * FROM t;
 or
select level
from dual
connect by level < 100

以下是我在MySQL SQL中的想法

select *
from
  (select @level := ifnull(@level,1) +1  as prev
  )a
where a.prev < 100;

但子查询不会动态执行
