Our tool to practice SQL uses a JavaScript implementation of SQLite. The database is created in your browser and you can change and add tables and values within individual tables. Feel free to use any SQL command and change the Database as much as you like.

To restore the Database to it’s original state, simply click the “Reset” button. If you like to change data and practice across browser sessions, you can download the database to your local machine and upload it later to continue.

All changes are stored on your machine and each user has their own copy of the original database.

Full functionality of our tool is supported by all modern browsers with enabled JavaScript.
