----------------------------------

    Resolution: Not A Bug

As this is not a bug in Asterisk, I'm going to go ahead and close this out as "Not a bug". However, please feel free to comment on this issue with any feedback you receive from the MySQL team, as that will help others who run into this problem with the MySQL ODBC connector.
