oracle分页有通用写法

oracle分页有通用写法,假设一页5行
select * from （
    select t.*,rownum from (
        select * from table1 where condition order by column) t )
    where rownum>(pangeNow-1)*5 and rownum<=(pageNow)*5

如果基础查询不需要排序，可以省掉一层嵌套
select * from （
    select t.*,rownum from table1 t where condition )
    where rownum>(pangeNow-1)*5 and rownum<=(pageNow)*5
