Our mission & values

Personalized learning
Every learner is different. Our mentorship program adapts to your pace, goals, and skill level, from beginner to professional.
Practical first
No theory without practice. Every lesson includes real SQL you can run, real results, and real scenarios you face on the job.
Free & accessible
All our course content is completely free. We believe quality SQL education should be accessible to everyone, everywhere.
Why CodeWithSQL exists
CodeWithSQL was born from a simple observation: most SQL learning resources are either too academic or too shallow. They teach you the syntax but not the thinking. They show you SELECT statements but not how to design a database that won't fall apart at scale.
We built CodeWithSQL to bridge that gap: a platform where beginners can start from zero and progressively build real-world database skills, guided by professionals who work with SQL databases every day in enterprise environments.
Whether you're a student preparing for your first tech role, an analyst who needs to query data more effectively, or a developer who wants to understand what's happening behind the ORM, CodeWithSQL is built for you.
Meet the founder
With extensive experience in enterprise technology solutions, database architecture, and full-stack development, Muhammad Abbas founded CodeWithSQL to share practical SQL knowledge with learners worldwide.
His professional background spans Microsoft Dynamics 365, enterprise asset management (EAM), data warehousing, and cloud solutions, all of which rely heavily on well-designed SQL databases. This enterprise experience shapes how CodeWithSQL teaches: not just the syntax, but the real-world design decisions, performance trade-offs, and security considerations that matter in production systems.
Muhammad also leads DynamicUnit, an enterprise technology consultancy specializing in Dynamics 365, ERP, data, and cloud solutions for businesses across the Middle East and beyond.
How we write and check content
Lessons and SQL examples
Lessons are written for CodeWithSQL. On 7 October 2026 we ran every SQL example on the lesson pages, in page order on a fresh database, against MySQL 8.0.46, MariaDB 10.4.32, SQL Server 2025 (17.0.1135.8, Enterprise Developer Edition), SQLite 3.39.2. Each example is labelled with the engines that accepted it without an error.
Running without errors shows the syntax was accepted; it does not show that every engine returns the same result. Examples that create users or databases or change server settings are not run. PostgreSQL and Oracle were not part of the run, so no example is marked as running on them. Each chapter explains the syntax differences that matter for its topic.
Tool reviews and comparisons
Reviews, "best" and "alternatives" guides and comparisons are research-based: written from vendors' documentation, pricing and licensing pages and release notes, with the date each page was last reviewed or verified, and sources listed on pages that have them. We do not claim to have tested a product hands-on unless the page describes the test.
Star ratings shown on some reviews are editorial judgements based on that research, not benchmark scores or user ratings. Editions and prices change, so check the vendor's site before you buy.
Functions, errors, exercises and interview answers
Reference pages are written from vendor documentation and say which databases a function or behaviour applies to. Their SQL is not yet part of the automated example run described above.
Authors and corrections
