MediumRankingDENSE_RANKfilter on rank
DENSE_RANK assigns 1 to the highest value, 2 to the next
distinct value, and so on — no gaps. That makes "the Nth highest distinct
value" a one-liner.
Task: return the employees who earn the second highest distinct salary.
Several people can tie for it. Return name and salary, ordered by name.
