SQL trainer is an interactive sandbox for learning and practicing SQL queries in an Android application.

The app comes with a full-fledged database that includes real tables and ready-made data sets. You can not only complete prepared tasks from a large list with three levels of difficulty (easy, medium, and hard), but also create your own queries, explore the structure of the tables, and add, modify, or delete data.

Practice your skills with select, where, join, group by, and other key SQL constructs such as insert, update, and delete.
You can even create your own tables and write queries for them without worrying about breaking anything the database can be reset to its original state at any time.

The app includes reference materials on SQL and helpful tips, making it suitable both for beginners and for users with some experience.
