This is all well and fine, but if you're going to go commando and update a production system by hand you should have a backup plan in mind before you start. With SQL, that could be as simple as starting a transaction, doing your commando stuff, and committing it when you are satisfied. But don't do that. Why are you doing anything like that in production. Why why why.
