I learned off of Mode Analytics SQL tutorial. It's free and I use it as a reference when I forget syntax. From there, my learning style is to grind on practical questions that I would get as a data analyst.

There was a comment here about using Leetcode, Hackerrank, SQL fiddle, etc to keep learning SQL.
