SQL Fiddle is a free website that you can use to demonstrate and save a query example in any one of 13 different DMBSs (as of this posting) including two different versions of SQL Server (2008 & 2012).
First you set up your work environment and “Build Schema”.
Then you can put in your query, run it, and see the output and even the execution plan.
At this point you can copy the link (for example the above at http://www.sqlfiddle.com/#!6/dbd09/1) and share it with others who can see it. You will see a lot of this on dba.stackexchange.com as it’s a great way to display a problem.
It’s also a good way to share demonstrations. I’m not sure I would want to us it to demo a stress test though ;).
