Terms of Service

These terms of service govern your use of SQL Reference, a free online SQL documentation site covering 762+ statements, functions, guides, and blog articles. The content is provided as-is for informational and educational purposes; while every entry is written and reviewed against the SQL standard and real database behavior, we make no warranty that the documentation is complete or error-free, and you should test queries before relying on them in production. You are welcome to browse, search, and run queries in the playground for any purpose, and to copy individual code examples into your own projects — code examples are provided for exactly that use. Automated scraping that degrades the service for other users is not permitted. The site displays third-party advertising to cover hosting costs. Questions about these terms can be sent through the contact page; how your data is handled is described in the privacy policy.
