And when you tried it what happened?

My job is working with Oracle databases. One of the best answers to many of the questions people ask is the title of this post. Oracle allows its software free for download for the purpose of development. All you need to do is get Oracle installed (either hit the Oracle documentation site or Howard J. Rogers' (dizwell) site.) Set yourself up a test case and run your command and see what happens. If you're still not sure, you can either check Oracle's support site, or, if you don't have support, visit Ask Tom. There are other Oracle sites, but those are the ones I mainly use.
