[Zope] More ZMySQLDA troubleshooting w/ Zope 2.0.0

[ben andrew fulton]

OK, so I figured out what it is that the interface doesn't seem to like
about my queries. First, a recap of the general error and traceback:

---

Error, exceptions.KeyError: unhandled 

SQL used:

select sessioncode
from users
limit 10

Traceback (innermost last):

After some trial and error, I discovered that db.py is apparently
bombing on columns of type bigint and mediumint. "sessioncode" in the
above example is a bigint column type, and if I select a char, decimal,
or smallint column instead, the query runs fine (although an unsigned
smallint will come back with an "L" appended to each number). I'm now
using MySQL version 3.22.25-log after upgrading my Debian installation
to unstable for the hell of it. Any idea what might be causing this
problem, and if there's a workaround I can implement in my query? Will
the MySQL db interface for Python that was just released into beta
handle this situation better?

Thanks, I hope I'm closing in on a solution,
