select * from (select A.*,rownum rd from (select * from [tablename] where [condition] order by  [condition] ) A  where rownum<=[endpage*pagesize]) where rd>=[startpage*pagesize];

1.select * from [tablename] where [condition] order by  [condition] 

按条件对数据表进行筛选排序，作为分页的基本数据

2.select A.*,rownum rd from (select * from [tablename] where [condition] order by  [condition] ) A  where rownum<=[endpage*pagesize]

使用rownum选择小于结尾页的数据，必须对rownum采用别名

3.select * from (select A.*,rownum rd from (select * from [tablename] where [condition] order by  [condition] ) A  where rownum<=[endpage*pagesize]) where rd>=[startpage*pagesize]

在2中得到的表中选择大于开始页的数据
