Hi,
I was wondering if there is an easy way to get a seq number column (1, 2, ....) for a select statement.
select empno, ename, 'seq' from emp
order by ename
==RESULTS==
empno ename seq

Hmm, it works for me.
SQL> select empno, ename, dname, rownum seq
  2  from (select empno, ename, dname
  3        from   emp e,
  4               dept d
  5        where  e.deptno = d.deptno
  6        order by ename
  7  );
     EMPNO ENAME      DNAME                 SEQ
