Codeacademy-like site for SQL?

yzT

Do you know any site similar to Codeacademy but for SQL? It's been a while (3+ years) since I used SQL, and I'd like to refresh my knowledge just in case I start to apply for BI positions

I didn't use Python for these years either, and just went through Codeacademy's tutorial and basically I refreshed everything

This is the closest thing I could think of

Back in the day, I used to use this:

SQLCourse - Interactive Online SQL Training for Beginners

Kahn Academy just released an online course, saw it come up in my news feed. Don't know if its any good or not.
