mysql实现oracle中的ROWNUM

实现分页的话

SELECT @rownum :=@rownum + 1 rownum,name

FROM

(SELECT @rownum := ((pageNo-1)*pageSize),name

FROM

mytest

LIMIT (pageNo-1)*pageSize,pageSize

) t

select *

from

( select *

from

(select *

from emp

where sal is not null

order by sal desc)a

where rownum<=3*3

order by sal )a

order by sal desc

limit 0,3

select * from table limit m,n

其中m是指记录开始的index，从0开始，表示第一条记录

n是指从第m 1条开始，取n条。

select * from tablename limit 100,50

即取出第101条至第150条，50条记录
