Database Administrators Stack Exchange is a question and answer site for database professionals who wish to improve their database skills and learn from others in the community. It's 100% free, no registration required.

Looking for a incremental SQL course that would likely be similar to the this Ruby Koan course; which is in fact inspired by the book, "The Little Lisper", which uses a short questions/simple answers style of learning.

Basically the format is short questions are within a well defined context, with a simple answer, that incrementally building and leveraging the student's knowledge within the subject matter, while keeping the to the short questions/simple answers style of learning.

Also, I just wanted to note that I know there are a number of ways to learn SQL, but I'm looking for an existing implementation of this way. This style provides a fixed-path with stepping stones, and if you do not finish a set of questions, you're not allowed to go on, and even if you were able to find a way to cheat this, it would just make things harder, not easier; meaning it's not just free-form learning with information present small packets.

w3schools.com/sql/default.asp ? –  gbn Feb 13 '12 at 14:33
    
@gbn: No, did you look at the Ruby Koan course I linked to? The W3Schools context does not follow the “short questions/simple answers style of learning”, unless I'm missing something. –  blunders Feb 13 '12 at 14:41
    
no, but it's a way to learn SQL that is free in short digestible chunks –  gbn Feb 13 '12 at 14:42
    
@gbn: I see, so it's more about providing a fixed-path with stepping stones than about free-form learning. Basically, if you don't finish a section of a lesson, you're not able to go on. –  blunders Feb 13 '12 at 14:47
    
for SQL, it may be better –  gbn Feb 13 '12 at 14:58

Have a look at:

This seems to be what you are looking for.

Not exactly question and answer type, but this is the best SQL tutorial I have seen so far: http://sol.gfxile.net/galaxql.html

+1 @yogirk: I tried it out, and agree it's nice. That said, within less than 5-mins of installing it I ran across one bug; the load file function referenced a file that does not exist. Also, on the first page of the tutorial it asks you to figure out how many seconds are in a day, but never says at any point to the user how to do it, or infer it from other examples; the answer being "SELECT 24*60*60". So, basically after those issues I stopped trying it, might try it more later, but also agree it not the format I describe; which leads to the student internalizing that material I believe. –  blunders Feb 13 '12 at 19:12
