Shameless Plug: If anyone here wants to practice their SQL, they are welcome to try my Mac app: TextQuery [1]. I built it because I wanted to quickly import CSV datasets and run SQL queries on them. I don't think there could be a more fun way to learn SQL than to jump in and start analyzing thousands of public datasets. Sure, you can use CLI/Code as well, but GUI is often faster and easier. Currently, the app is in the beta period and free-to-use. When launched, you'll get to keep the latest beta version.
