New Monthly SQL Practice for January 2025!

Ready for a new advanced SQL challenge? This time, you will help Sven, a manager at a telecommunications company in Norway. Get ready to dive into the world of SQL queries as you help Sven gain important insights into his customers. Welcome to the January SQL Practice course!

In our January 2025 SQL Practice, you will meet Sven. He is a manager at a telecommunications company in Norway. Sven has hired you, an SQL specialist, to help him build a series of queries using his database. Help him gain important insights into how his services are doing. Which plan is the most popular? How much data do his customers use each month? You will find all the answers in the data. You just need to figure out how to get them out of the database using SQL.

This SQL Practice is at an advanced level and is aimed at those who have finished our Window Functions course or otherwise have equivalent knowledge. If you are not yet comfortable working with window functions, check out our interactive window functions course and then come back here for more practice.

Our interactive SQL course is a great way to test your skills and put what you have learned so far into practice. The exercises are fun, so you do not get bored while learning. And thanks to the interactive online console, you write real SQL queries and see their results. There is nothing to install or set 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. LearnSQL.com 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 featuring 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. You can copy most of the SQL queries you write in these exercises and use them in your own projects. This is what they call a hands-on SQL course!

Who is this course 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.
