Sorry, I changed the sqlalchemy URLs, not the import statements.

FWIW I turned echo on, here's the log leading up to the second
exception:

This table is trivial:
CREATE TABLE  `rtu_prod`.`event_queue` (
  `idx` int(11) NOT NULL,
  PRIMARY KEY (`idx`),
  CONSTRAINT `event_queue_ibfk_1` FOREIGN KEY (`idx`) REFERENCES `events2` (`idx`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

every record appears to be populated with a normal int.

Title:
  InterfaceError truncated column

Bug description:
  I'm not sure if this is a bug, please bear with me.

  I just switched to oursql 0.9.2 from mysqldb 1.2.2. Running Python 2.6
  on win32. I am using SQLAlchemy 0.6.6. I didn't change my code, just
  the SQLalchemy import statements. I am now getting a bunch of
  exceptions.
