In this challenge you will write several MySQL queries to combine data by using the UNION set operator. First, you will develop a query that combines data from two result sets. Next, you will develop more specific queries that will combine result sets by removing and retaining duplicates. Finally, you will explore queries that will sort the combined result sets. Note: Once you begin a challenge you will not be able to pause, save, or return to your progress. Please ensure you have set aside enough time to complete the challenge before you start.
