Looking for an alternative way of teaching SQL, and wondering if there is a free/web-based game that requires knowledge of SQL to win. If possible, the game should not only be fun, but also track how much SQL the player knows.
You can try to win via SQL if you'll get up on the top of rating. Every SQL exercise solved shall put up you in rating.
I don't know of a gamified SQL learning tool, but I'll recommend The Manga Guide To Databases as a way to cut through the boredom factor. It's a fast read, even for retro-technical managers, and does a quick survey of how to design and use a DB.
