Also FWIW if I use the same example to connect to my MySQL 4.1 server I get a different exception

Title:
  InterfaceError truncated column

Status in oursql:
  New

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.
