Hi there! It's part 6 of our SQL course already. Wow! You're pretty skilled right now, but there are still some things left which you should know before you finish the course.

You will now learn how to operate on entire SQL query results. By the end, you'll be able to build unions, intersections and differences of two queries. Sounds vague? Don't worry, we'll explain everything for you.

Are you ready for another lecture? Good. Let's go!
