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
