Welcome! This is my personal journey through the book SQL for Mere Mortals by Michael J. Hernandez and John L. Viescas. I'm using this repo to post my progress, notes, and solutions as I work through the book's exercises and examples. It's a hands-on learning log more than anything else! 🛠️📚
I used SQL in my day to day job, this book helps clear up any missing gaps :)
SQL for Mere Mortals is a beginner-friendly, practical introduction to relational databases and SQL. It explains the fundamentals in a clear, non-intimidating way—perfect for folks who are new to databases or want a solid refresher.
This repository includes:
- ✅ Completed exercises from the book
- 📝 Notes and observations as I go
- 💡 My takeaways and key concepts per chapter
Each folder or file corresponds to chapters or specific sets of exercises.
I'm learning by doing—and sharing. Posting my solutions here keeps me accountable and helps me solidify what I’m learning. If you're also going through the book, feel free to browse or even follow along!
⚠️ Disclaimer: These are my answers and interpretations as I learn. They may not be perfect, and that's okay—this repo is part of the learning process.
If you're learning too, here's how you might use this:
- Compare your solutions with mine
- Review SQL concepts and examples from a learner's perspective
- Watch the progression as concepts build over time
- SQL (Standard SQL syntax used throughout)
- TSQL for specific queries (the book promotes all SQL variants, but I am using TSQL.)
I'll update this regularly as I move through the chapters. Keep an eye on the commit history to see what's new!
This is a personal learning project, so I’m not accepting pull requests—but feel free to open an issue if you spot a mistake or have a question. I'm always up for learning more.
