Set Operators

The Set operators combine the results of the two queries into one result. The INTERSECT returns all the distinct rows selected by both queries. The MINUS returns all discrete rows selected by the first query but not by the second. The UNION returns all the discrete rows selected by either query. The UNION ALL returns all the rows selected by either query, involving all the duplicates.
