hi *,
the query as follows....

select dbms_rowid.rowid_row_number(rowid),rownum from scott.emp;

dbms_rowid.rowid_row_number(rowid)	rownum
----------------------------------	------
				0	1
				1	2
				2	3
				3	4

4 rows selected.

Why the first column(dbms_rowid......) starts from 0 and second col.(rownum) from 1?

TIA.
Regards..
