What's the fastest way to learn SQL?

Question

I recently joined a startup and I didn't realize how much I would need to be able to write off-the-cuff queries to debug stuff. I came from a massive company where running adhoc queries was basically a giant no-no and never really got familiar with SQL. Any tips on the best way to pick it up quickly so I can start being more productive at work?

I like the SQL course at https://www.hackerrank.com/ see also books by https://en.wikipedia.org/wiki/Joe_Celko to learn how to write really advanced queries.

OpenAI is a better SQL query writer than any developer I&rsquo;ve worked with, and it&rsquo;s not close.
