>I want to know how I can access a database for which I have no permissions. When I perform an insert, it fires a trigger that calls other procedures which reference a database to which I have no permissions to access and I receive an error. Therefore, I want to know if you can tell me which user name and password I can use to access the database.

You cannot access a database you don't have permissions to. You have to obtain proper credentials in order to do that.
