Take the SQL challenge! Solve everyday problems, and have fun while doing it!

Practice SQL like never before. We have collected all of our Monthly SQL Challenges published in 2020 into one SQL course. With over 160 interactive exercises in one place, you can keep your SQL skills fresh by practicing SQL in real-life scenarios.

We publish SQL Challenges every month on These mini-courses have 5 to 10 SQL exercises. They are perfect for practicing your newly acquired knowledge and going beyond our course offerings.

We broke the convention of ordinary exercises to give you more unique tasks, each related to a specific topic. You will have the opportunity to play the role of a snowboarder looking for the perfect destination for the holidays, a stargazer, a car repair shop owner, and a bakery owner.

You can also practice SQL while traveling around the USA, looking for the perfect pizza place in Chicago, or designing a garden. We have created 12 different topics in which SQL can be unexpectedly helpful. Check out what else we came up with!

Some SQL Challenges will be easier. Others are more difficult. However, do not be intimidated. If you know the basics of SQL (e.g., you have completed our SQL Basics course), you will surely do well.

The exercises are designed to be challenging but doable for beginners. Remember, if you have a problem with something, you can always get hints or support. When you encounter difficulties, you will learn what you need to focus on and go over again.

What are you waiting for? Practice SQL, and have fun!
