Free SQL Help for Devs, DBAs, and the Curious

SQLSupport.org is a technical knowledge hub built for people who develop, design, maintain, and troubleshoot production database systems. This site exists to provide clear, practical guidance for database administrators, developers, architects, and engineers who need answers that actually work.

Every article on this site is written from real world experience. The content comes from years spent designing, repairing, tuning, and maintaining enterprise database systems. These are not recycled vendor tutorials. These are field tested solutions based on real failures, real constraints, and real performance demands.

This site focuses on practical topics such as

Performance tuning for large production systems
Index and query optimization
Backup and recovery strategies
High availability and disaster recovery
ETL pipeline design and troubleshooting
Security and compliance design
Architecture patterns that scale
Common production failures and how to fix them

There is no paywall and no gated content. There are no sales pitches and no sponsored posts. SQLSupport.org exists for one purpose

To provide free, accurate, production grade technical guidance to anyone who works with data.

New content is added regularly and existing articles are continuously refined as new techniques and platform changes appear. The goal is not to publish content for traffic. The goal is to publish content that helps people solve real problems.

If you see something that could be improved, corrected, or clarified, your feedback is welcome. This site improves through real world experience shared by real professionals.

If you are responsible for systems that must be reliable, secure, and fast, this site was built for you.
