Try this:
select * from emp_table where rownum <= 5
or
select * from emp_table where rownum between 1 and 5

SELECT * FROM emp
WHERE hiredate >= (SELECT hiredate FROM emp a WHERE 5 = --change the '5' to chose more vals
(SELECT COUNT(DISTINCT(hiredate))
FROM emp b
WHERE b.hiredate > a.hiredate)
AND ROWNUM < 2 AND hiredate IS NOT NULL);
