Hi,
Can anybody please explain me the flow of the below query.
I am not able to understand how this query works.
This query is for finding the Nth highest salary..
SELECT DISTINCT (a.sal)
FROM EMP A
WHERE &N = (SELECT COUNT (DISTINCT (b.sal)) FROM EMP B
WHERE a.sal<=b.sal);
If N = 2 then second highest salary will be the o/p.
If N = 3 then third highest salary will be the o/p.
and so on..
Thanks,
Nitin
