Write an SQl Query, N can be anything
You are given a relation R with N columns of the same type.Write an SQL query that returns the tuples (perhaps more than one)having the minimum number of different values. The solution shouldhave size polynomial in N and use aggregation in an essential way.Examples: 1. R1 = {t1 : (a, a, b),(t2 : (b, a, c)}. The result ist1. 2. R2 = {t1 : (a, a, b),(t2 : (b, a, c), t3 : (b, b, b)}. Theresult is t3. A part of the solution is devising a way to uniquelyidentify tuples without introducing the notion of a tupleidentifier.
