can anybody pls tell me logic to spliting the sql query by using rowid through dba_extent... my sql query reports are running for quite long time, for speed up the processt i need to split the query.. i heard it can be done through split the rowid's..

Already the query is tuned.... Data extraction is some millions of records..
query is reading most of data from single table. from that table, can we split the query through range between the rowid ?

We use

Select ....
From yourtable
where rownum < somenumber;

rowid is a physical location I am told.
