I’ve been trying to get a handle on SQL, but I’m running into a bit of a roadblock. I understand that SQL is essential for managing and querying databases, but I really want to practice my skills in a hands-on way. The issue is that many platforms that offer SQL courses either charge a fee or require a subscription, which isn’t feasible for me right now. I’m looking for free resources where I can not only learn the theory but also get real practice through exercises or projects. It would be great to find a platform that allows me to work with actual databases and write queries. I’ve checked a couple of websites, but they all seem to have limitations or hidden costs. I’m also concerned about the quality of the resources; I want to ensure I’m learning the right techniques and best practices. Ideally, I’d prefer an interactive environment, where I can write SQL code and see immediate results, rather than just reading through tutorials. Does anyone have recommendations for free platforms or tools where I can practice SQL effectively? Any advice would be greatly appreciated!
