New Monthly SQL Practice for October 2023!

In our October 2023 SQL Practice, you meet Sophie. She manages an online business for publishing and printing books and needs you to access and present various statistics to help her grow her business. Can you use your SQL skills to help? It should not be too hard if you have finished our SQL Basics courses or otherwise understand core SQL concepts.

Our interactive SQL course is a great way to test your skills and see if you can put what you've learned so far into practice. Our exercises are fun, so you will not get bored while learning. And thanks to the interactive online console, you write real SQL queries and see their results. You do not need to install or set anything up. A web browser and your willingness to practice SQL are enough.

Maybe this is the first time you’ve come across our Monthly SQL Practices. offers one SQL Practice each month: basic levels on even-numbered months and advanced levels on odd-numbered months. Each SQL Practice takes about an hour (or less!) and contains 5–10 exercises to help you hone your skills.

Each Monthly SQL Practice features a different business or hobby. We’ve had practices that feature family trees, a language school, a book exchange, a job agency, rental cars, stars and astronomy, auto repair, baking, pizza, movies, U.S. cities, and more.

Our exercises are based on real business scenarios. There are no abstract theories here, just everyday business problems. Most of the SQL queries you write can be copied and used in your own projects. This is what they call a hands-on SQL course!

Who is this course for? For everyone, especially beginners who need to practice SQL. We believe this is the only way you truly learn something. Knowledge is helpful only when you use it in practice.

If you are a basic SQL user who knows how to join tables and group and filter data, check your knowledge with October’s SQL Practice!

Hungry for more SQL exercises? Check out our SQL Practice track featuring over 600 interactive SQL exercises. You’ll brush up your SQL coding skills before you know it!

Have fun and start practicing SQL now with our October 2023 SQL Practice!
