I am a business user that needs to use generated sql. Unfortunately, there are few column names that needs to be changed everytime. This is an easy job for a pyton script, but those kind of things are bad in work environments, I cannot assume the guy after me knows python. That's why I am always happy to pay for software when it comes to business environments - you know you will have a good UI (if you choose well and stay away from oracle) and possibly good support.
