Hey, I'm looking to learn more back-end managing as I'm primarily a front-ender. So, maybe you could suggest some learning resources? Idealy free, but I know it's not always possible. I've already completed a couple of courses on the internet mainly https://www.bitdegree.org/course/sql-course and been on YouTube, Google (that's how I ended up here), but couldn't find anything else.

Thank you!

Although mysql is language agnostic what are you using php?

The official mysql manual is pretty good but not that user friendly. There are some examples on w3schools that are OK https://www.w3schools.com/sql/default.asp

I should add that a good Mysql GUI (not phpmysql!) is a great tool to have as you can test and practice to your heart's content. I like SQLyog - I believe they still have a community version. There are loads of other ones available for your operating system though.
