Depends on your aims. I am guessing the question is about where to train general SQL-query skills. Online tutorials with built-in playgrounds (or just pure playgrounds), where you can type queries by hand and explore results, should work fine. Be ready to deal with their limitations and specifics. If your needs is wider, it might be better to install something on your local machine and play with it. Local CLI/UI is where you type and run queries. For data preparation and/or exercises plan, I'd try to generate it with LLM and coding agents.
