So... You are saying, people should beware of DBAs (Database Administrators... AKA DB Gods) having the possibility to do SQL injection? Riighhtt... And why should they go through the trouble of exploiting a webapp to manipulate data in the DB? They're DBAs... As in they already CAN manipulate the data in the database since they sort of ADMINISTER it!
