1. How do I run a basic SELECT query in this online MySQL compiler?

Use the SELECT statement to retrieve data from a table.

To retrieve specific columns:

You can also filter records:

Enter the query in the Code Editor, click Run, and review the returned rows in the Output screen.

Yes. You can create sample tables, insert data, and test supported MySQL joins within the online environment.

After adding records, you can test an INNER JOIN:

This is useful for learning how relational tables work together.

No. You can use this Online MySQL Compiler / SQL Runner directly from your browser without installing MySQL Workbench, XAMPP, or a local MySQL server for supported exercises.

A local or hosted MySQL environment may still be required for production databases, persistent data, authentication, backups, large datasets, external application connections, or advanced server administration.

Yes. MySQL is a relational database management system (RDBMS). It stores structured data in tables made up of rows and columns, and relationships between tables can be created using keys.

For example:

You can then connect the related data with a join:

This relational model makes MySQL useful for backend applications, content management systems, e-commerce platforms, dashboards, and many other structured-data projects.
