Thanks for the advice. Just to clarify a little bit, I do have a few projects that I would like to work on, but my main concern right now is I don't want/need to be working on a live server.

I'm looking for a 'dummy version' that allows me to create some tables, join tables, delete tables, and mainly query these tables - without needing to setup a server to do it. The only reason I mentioned MySQL is that was the one suggestion I did receive, but after installing it, the first prompt asked for my server information and it wouldn't let me get around that first step. I would prefer to learn SQL through Microsoft SQL Server, but it seems more server-based, so I'm not sure if it would allow me the functionality to just mess around with files on my c: drive and not sending them through a linked server?

Maybe it doesn't exist, but I'm just trying to find something that will let me upload some excel worksheets and use SQL commands to mess with the data. I have all the data created, I just need the right functionality to allow for this.

And, again, forgive me if this doesn't make sense - I'm still learning all of this... I just want something to play around with, without the severity of messing stuff up on a server! 😛
