If for whatever reason you need to drop all of your tables, and cannot delete an recreate the schema... run this and spool it's output into another sql script...

The first thing that you when you want to come here is type in their address in the address bar of your internet browser and hit go and the website appears... seems simple enough, but there are a few things going on behind the scenes
