It is indeed very helpful, actually my first class in CS colleague was SQL in oracle. I think that's one of the class that is most valuable to me without my realising it. Until now I still remember most of the language because I used it every day, it has similar syntax and understanding even when I convert to Mysql or Postgres. Without realising it is one of the most important fundamentals that is nailed in your head, suddenly you just understand when you look at raw SQL from your ORM to debug, what went wrong etc.
