oracle中分页查询教程

select *

from ( select rownum as rowno, t.*

from table t where rownum <= page*size) table_aliaswhere table_alias.rowno > (page-1)*size;

有order by语句的分页:select *

from ( select rownum as rowno,r.*

from( select * from table t

order by t.element asc

) r

where rownum <= page*size

) table_alias

where table_alias.rowno > (page-1)*size;

上限条件必须放在子查询，而下限条件必须放在外层查询 (rownum总是从1开始的，第一条不满足去掉的话，第二条的rownum 又成了1)。

顺便提一下 :mysql中分页查询sql格式是：select * from table limit m,n;

其中m是每页起始页码，n是每页显示的条数，m =( pagenum - 1) *n
