Sandbox and Lab Environment
SQL, like any other coding language, is best learned by working hands-on with code.
With our online SQL editor, you can edit the SQL statements, and view the result in your browser:
If you want to explore more and host your project, we have a feature called Spaces that allows you to build, test and deploy static websites for free.
Here you get a secure sandbox environment called Spaces, where you can practice coding and test projects in real-time.
Spaces allow you to test, build, and deploy code. This includes a W3Schools subdomain, hosting, and secure SSL certificates.
Spaces require no installation and run directly in the browser.
Features include:
- Collaboration
- File navigator
- Terminal & log
- Package manager
- Database
- Environment manager
- Analytics
SQL Certification
W3Schools offers an end-of-pathway certification program.
Here you can take exams to get certified.
The SQL exam is a test that summarizes the W3Schools SQL syllabus.
After passing the exam you get the "Certified SQL Developer" Certification.
There are two different types of certifications:
- Non-adaptive
- Adaptive
The non-adaptive is pass or no pass.
The adaptive certification is adaptive and graded; students will get a grade from intermediate, advanced to professional.
