SQLMentor is a free, educational platform designed to help developers, data engineers, and database administrators learn and practice SQL across multiple database systems including Oracle SQL, PostgreSQL, PL/SQL, SQL Server, SQL*Loader, and IBM DB2.
The platform provides learning tracks, certification practice exams, an in-browser SQL editor, and a general SQL quiz — all at no cost and without requiring account registration.
All written content, SQL examples, quiz questions, certification practice questions, code samples, and educational materials on SQLMentor are the intellectual property of SQLMentor unless otherwise noted. This includes all text, graphics, and compilation of content.
SQLMentor uses several open-source libraries, each governed by their own licenses:
"Oracle", "Oracle SQL", "PL/SQL", "SQL*Loader" are registered trademarks of Oracle Corporation. "PostgreSQL" is a trademark of PostgreSQL Global Development Group. "SQL Server" is a trademark of Microsoft Corporation. "IBM DB2" is a trademark of IBM Corporation. SQLMentor is not affiliated with, endorsed by, or sponsored by any of these organizations.
The certification practice exams on SQLMentor (including 1Z0-071, 1Z0-082, 1Z0-149, DP-300, and PG-A) are created for educational and practice purposes only. They are not affiliated with, endorsed by, or sourced from Oracle, Microsoft, or the PostgreSQL Global Development Group.
The SQL editor runs entirely in your browser using sql.js (SQLite compiled to WebAssembly). All query execution happens client-side — no data is sent to or stored on any server.
The editor is provided as-is for learning and experimentation. It simulates multiple SQL dialects but may not fully replicate the behavior of production database systems. Do not rely on it for production use cases.
All content on SQLMentor is provided for educational purposes. While we strive for accuracy, SQL syntax, database behavior, and best practices evolve. Always verify information against official documentation for your specific database version.
