Red-Gate [SQL Data Compare][1] will do this. Just create a blank data base with the same schema, and run a compare against the original and the blank database. It will generate scripts to insert all of your test data.

Verging on religious but I would say that you're painting an overly grim picture of the state of modern OOP.
