Here is an awesome set of our Advanced Monthly SQL Practice Sets from 2021. Enjoy!As an experienced SQL user, you already know the importance of SQL practice. To master a new skill, you need to be able to apply it in real situations. That's why we created Advanced Monthly SQL Practice Sets. We've gathered those from 2021 in one interactive SQL course.
We publish our SQL Practice Sets once a month. Each set is an interactive mini-course with 10 to 20 hands-on SQL exercises.
We know how difficult it is to gain experience in using advanced SQL functions. There simply aren’t enough online courses of this type out there. With our Monthly SQL Practice Sets, practicing writing sophisticated SQL queries has become much easier.
If you are new to SQL, perhaps start with 2021 Monthly SQL Practice Sets - Basic first. Have fun while practicing the basics; once you have mastered the basics, come back for more! And if you are a complete SQL novice, get started with this SQL Basics course.
We create our courses based on real business scenarios. We don't want to give our users abstract challenges or examples that have no real-world background. You can use the practice SQL queries you write to solve our Challenges in your real projects. See how SQL helps your business grow!
The difficulty of our SQL exercises is such that they are challenging for advanced users but not so challenging that they discourage you from learning SQL. If you have a problem somewhere or get stuck in a task, you can always get tips or ask for support.
You solve all the exercises on our online platform. You don't need to install or set anything up. All you need is your favorite web browser.
