Select rownum,empno,ename,sal from(select rownum,empno,ename,sal from emp order by sal) having rownum=&n;

Use the top-analysis feature which introduce from oracle 8i:

SELECT rownum, empno, ename, sal
FROM (SELECT empno, ename, sal from emp 
           ORDER BY sal )
WHERE rownum < n; (n=any valid integer)

Thanks,

SELECT LEVEL, MIN(Sal)
FROM Emp
WHERE LEVEL = &LevelNo
CONNECT BY PRIOR Sal < Sal
GROUP BY LEVEL

TO find out nth LOWEST value, e.g. salary from emp table without using ROWNUM & DESC/ASC

SELECT DISTINCT (a.sal) FROM EMP A
WHERE &N = (SELECT COUNT (DISTINCT (b.sal))
                       FROM EMP B
                       WHERE a.sal >= b.sal);
