FROM emp a 
WHERE (
       SELECT COUNT(DISTINCE sal)

Answer 1

Now you try this you will get for sure:

SELECT DISTINCT sal 
    FROM emp a 
    WHERE (
           SELECT COUNT(DISTINCT sal) 
           FROM emp b 
           WHERE a.sal<=b.sal)=&n;

For your information, if you want the nth least sal:

SELECT DISTINCT sal 
FROM emp a 
WHERE (
       SELECT COUNT(DISTINCT sal) 
       FROM emp b 
       WHERE a.sal>=b.sal)=&n;
