Hi all! I am interested in sql and studied a lot of materials on this topic on the Internet, but I lacked confidence in my qualifications. Wanting more practice, I turned to Google for problems and came across a resource called sqltest.online. This site is great for those who want to test and improve their sql skills. No matter your experience level, you’ll find a wide range of challenges here, from simple to complex.
I especially liked the variety of problems of varying difficulty, allowing you to test knowledge at different levels. You can choose a language (Russian or English) and start solving problems without preliminary database settings.
The site presents more than 200 problems in 17 categories of various databases. New tasks are constantly being added, making learning even more fun for everyone.
No registration is required, just go to the site and start solving problems. The site also has an active community in the Telegram channel, where you can discuss interesting points, share experiences and get help.
One of the advantages of sqltest.online is its accessibility. You can use the platform at any convenient time, which is especially valuable. This allows you to develop skills in using SQL in your free time or between tasks.
In addition to self-help tasks, the site also offers educational materials for a deeper understanding of sql. This helps not only to test your knowledge, but also to deepen your study, broaden your horizons and improve your skills.
I recommend anyone who wants to improve their sql skills to join this project. I myself solved about 30 problems and was satisfied with my choice. I felt that my professional skills began to develop. So, if you are interested in this, I recommend paying attention to this platform!
