In this challenge, you will write several Transact-SQL queries to summarize and group data. First, you will launch Microsoft SQL Server Management Studio (SSMS), and then you will develop a query that summarizes data by using the GROUP BY clause. Next, you will develop more specific queries that include multiple aggregate functions to summarize data. Finally, you will explore queries that filter data by using the HAVING clause. 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.
