This may not address your specific problem, but it may help solve it (and
potentially others). I had many problems when using MySQL with ODBC and
Zope. I switched to MySQL Python libraries and ZMySQLDA and have had no
trouble at all. Get ZMySQLDA from
http://www.zope.org/Members/adustman/Products/ZMySQLDA and then download the
MySQLdb python library. This might take care of your problem.

Subject: [Zope] MySQL Database not working well with Zope
I'm new to setting up my own Zope and MySQL
Servers, so I'm not sure if I just didn't configure it
correctly or what, but I'm now getting errors when I
try to connect to my MySQL server.
I'm currently using Zope 2.5.1 and MySQL Max
3.23.51 with the myodbc-2.50.39-nt package, and
connect to the MySQL server using the Z ODBC Database
Adapter Product. The root of my Zope installation is
J:\Zope_2-5-1\Ricepail_Com. It seems to be set up
correctly, as it was working fine at first. When I
entered some data into a table I created, it worked
fine with zope. However, when I tried to add longer
entries into a cell of type "text" (smaller,
2-sentence entries worked fine) the database stopped
working, and I'd get the following error page:
Zope Error
Zope has encountered an error while publishing this
resource.
Error Type: sql.error
Error Value: None

sql.error: (see above)
I continue to get the above message nomatter what I
do, until I restart the Zope Server.
I think that the error has to do with the Product I
installed and the size of the entry, because when I
delete the row with the long entry and restart Zope,
everything works fine again. I've tried altering what
I entered into the database, changing the length of
several of the values, but it still doesn't work when
I make the "text" entry more than about 100
characters. When I go to a command-line interface,
and try to show the contents of the database table,
everything seems to look correct.
Can somebody please help me fix this problem????
