What are the best platforms to learn SQL from scratch?

I've found that self-directed exploration works best for me rather than structured courses. Try building and breaking things with SQL on your own, and interact with the official documentation. You'll develop a better understanding that way than just following an instructor's path.

If you're looking for a bit of theory, you might want to check out GeekforGeeks. Their SQL tutorials have been really helpful for many people. Also, start with the basics of relational databases; understanding that foundation will pay off later.

W3Schools is another great resource for learning SQL. Their sections are quite detailed, and I always go back to it when I need to brush up on something. It’s a perfect place for beginners to get started!

You should check out Mimo! It's a free mobile app that's like Duolingo for programming, and it has a solid SQL course. I did about half of it before my college SQL class, and I felt really well-prepared. Just a heads-up, it doesn't cover setting up SQL servers, but there are plenty of great YouTube tutorials for that. Once you're comfortable with the basics, look into SQL Server Management Studio; it's a free tool from Microsoft for managing databases.
