In database application, the times that ordering and paging the result selected according users demand is great.At first, this pager shows the ROWID in Oracle database and the relationship between ROWID and B-tree.Then, it shows the functionality of ROWNUM.At last, it shows the difference between the conventional paging method and the new paging method take use of ROWID, and makes contrast with two methods on execution cost.
