Oracle对没有主键的表分页

scott.emp.* from scott.emp left join (select empno id, rownum num from scott.emp) id_num on scott.emp.empno = id_num.id where id_num.num between 5 and 10;

假设遇到没有主键的表能够尝试rowid取代。rowid不会由于排序或者查询，甚至update都不会改动，因此能够借助这个字段作分页。

select scott.emp.* 
from scott.emp left join 
    (select rowid id, rownum num from scott.emp)  id_num 
    on scott.emp.rowid = id_num.id 
where id_num.num between 5 and 10;
