Is there a way to try out sql commands like jsfiddle.net [closed]

Question

I'm really impress by jsfiddle.net where we get to try out html/css/js right in front of us.
Does anyone know of a similar set of screens for sql where you could get to try out commands and build tables in a similar 'virtual' environment.
Of course I would like it to support all the different flavors too - mySQL, SQLserver, DB2, Oracle, Postgres, etc. And each of their various versions too please (yes I am smiling and really wishing here).

Answer 1

This might be one option that covers all the vendors, but you can't create your own tables etc.

Another is http://sqlize.com/ which does let you create tables, though it is only mySQL.
