Second this. I'm an electrical engineer who writes SQL queries daily. Knowing where your data is, how it is organized, and enough tools to do something with it: SQL, Excel, Python, R...etc is vital for making business decisions.
W3Schools has a good SQL tutorial I recommend to new engineers. After that just try to use it and use stack overflow when stumped. Easy things are easy, but some harder things can be difficult for some to grok.
