man you are wonderful. You are the only I guy I have seen that writes FROM before SELECT, which is how it should be

[@devsagar5812]

Alternative if interviewer ask to not to use windows functions: CREATE FUNCTION getNthHighestSalary(N INT) RETURNS INT BEGIN SET N = N-1; RETURN ( # Write your MySQL query statement below. select distinct salary from Employee order by salary desc limit 1 offset N ); END
