No friends,
rownum is one of the column name of table like
emp_no,emp_name etc. if u have not rownum column in ur
table,how to solve it.
we can retrieve this record through physical location that
is using rowid not rownum.
select min(rowid) from emp not in(select min(rowid) from
emp not in(select min(rowid) from emp));
