Hi there! It's part seven of our T-SQL course already. Wow! You're pretty skilled by now, but there are still some things left that you should know before you finish the course.

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

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