SQL stands for Structured Query Language and is the language used to interact with relational databases - and, increasingly, non-relational databases as well! The basics of set-oriented, declarative SQL are picked up quickly. You can then spend the rest of your life deepening your expertise in this rich language. One way to do that is with our weekly SQL tournament quizzes, most of them written by our amazing SQL Quizmaster, Kim Berg Hansen.

Each Saturday, we publish a brand-new quiz on SQL that is part of our tournament series and available for play in the coming week. This means you can play competitively, ranked against other developers, or you can take the quiz simply to strengthen your knowledge of SQL.
Dev Gym quizzes, workouts and classes offer a form of "active learning": watching a video or reading a blog post
is a great way to learn,
but think about it. If you want to get stronger, you can't just read a book about lifting weights.
If you want to get more flexible, watching a video about stretching will only get you so far.
To get better at writing code, you need to write code and you need to be able to read/understand code.
Take our quizzes to strengthen your code comprehension skills and keep key language features fresh in your mind and fingertips.
