> Introduce basic set operations:
> 1. Intersection: The intersection of A and B, denoted by A ∩ B, is the set of all things that are members of both A and B.
> select set_intersection(arr_a, arr_b) from dual
> 2. Union: The union of A and B, denoted by A ∪ B, is the set of all things that are members of either A or B.
> select set_union(arr_a, arr_b) from dual
> 3. Symmetric difference: the symmetric difference of two sets is the set of elements which are in either of the sets and not in their intersection.
> select set_symdiff(arr_a, arr_b) from dual
