Νίκος, I am glad that you solved the problem.
I am not using mysql but postgresql. When I get a problem using python to communicate with the database, one of my first steps will be to determine whether the error is a python (maybe psycopg-related) related error or a database error. What I do then is to use the string python is sending to the database and try to run that on the commandline interface to the database (psgl) or something like pgadmin3. Mysql have similar tools. Once you have determined that it a database related problem, it should be easy to sort it out on that side. If it works on the database the rest of the problem should be solved on the python side. Maybe this approach would have saved you some time. Regards Johann -- Because experiencing your loyal love is better than life itself, my lips will praise you.
