Use Python 2.4.3 (MSI installer) and SQLObject 0.7.1 installed with python setup.py install from tar.gz on WinXP. Connect to MySQL 4.1.11 server on another machine and create the table in a database (read on below):

Create a class from the database:

__connection__='mysql://user:pass@sql_server_host/dbname'
import sqlobject as SO
class Termek(SO.SQLObject):
class sqlmeta:
fromDatabase=True
idName='sorszam'

You should get the following exception:

    Fixed in the SVN in the revision 1997 in hte trunk, r1998 in
    the 0.7 branch. Meanwhile replace the offending line with:

    if self.kw.get('use_unicode') and colClass is
    col.StringCol:
