Someone wrote a function called GetEmployeeCount that deletes all employees from the database, executes it, rolls back the transaction, and returns the result. Technically, ExecuteNonQuery() does return the number of affected rows, so you'd get your employee count. Just, you know, with a brief moment of existential terror for the entire database before the rollback kicks in. It's like counting how many people are in a room by kicking everyone out and seeing how many complained, then using a time machine to undo it. Sure, it works. But your DBA is going to have questions when they see those transaction logs.
