Consider the relational schemapart(part_id, name, cost)subpart(part_id, subpart_id, count)where the primary-key attributes are underlined. A tuple (p1, p2, 3) in the subpartrelation denotes that the part with part_id p2 is a direct subpart of the partwith part_id p1, and p1 has 3 copies of p2. Note that p2 may itself have furthersubparts. Write a recursive SQL query that outputs the names of all subparts ofthe part with part-id 'P-100'.
