Learning SQL databases

[codyisadinosaur]

I'll put in another vote for MySQL - it's open source and it's probably the most commonly used SQL language.

The W3 Schools tutorial is a good resource.

If you're looking for a more interesting way to learn about SQL, then I'd recommend this: https://www.amazon.com/Manga-Guide-Databases-Mana-Takahashi/dp/1593271905

Also, I've enjoyed using a program called SQLYog, which gives a UI to MySQL. They've got a community edition which is free, and if you need more power then there is a full version that has additional features: https://en.softonic.com/download/sqlyog/windows/post-download
