Hi @jb. This tracker is for reporting bugs in the core Python language. While it's possible that what you're experiencing is due to a bug in core Python, on the information given it's likely that the problem is either in your own code, or in whatever database driver code you're using. In either case, I'm afraid this tracker is not the appropriate place to seek help.

For general debugging help, you could try any of the various dedicated Python groups and mailing lists (for example, discuss.python.org), or something like Stack Overflow. Be prepared to give details of exactly what you did, what you expected to happen, and what actually happened, along with code that will help others reproduce your issue.

I'm going to close here - currently, there's nothing useful that the Python core team can do with this report. The issue can be re-opened with more information after further investigation, if that investigation produces reasonable grounds to suspect a core Python bug.
