I understand that you think you have a lot of background and that you can, therefore, just open a book or a web site, find a few syntax differences and be competent: Nothing could be further from the truth.

The reason we are reacting to you the way we are is that you are like a guy that jumps out of a plane without a parachute and after falling 25,000 feet says ... "so far so good."

I teach approximately 60 students per year at the graduate level. All have at least a CS degree and most at least 10 years in the industry working with Sybase, SQL Server, Informix, or DB2. Some have years of experience with Oracle too. Each and every one of them would find what you propose to do as ludicrous as we do. We are being harsh here to hopefully disuade you from an act as foolhardy as jumping out of an airplane without a parachute. Ignorance of what you don't know makes the task seem far simpler than it is.

The best advice is not always the advice you want to hear. And the fact that you couldn't answer the question, above, that my first year students can answer after their first 3 hour class indicates how far behind you are.
