[Zope] Problems inserting into MySQL

[Ed Leafe]

	I'm working on a site whose data is stored in MySQL. So far I've 
had no problems with the database connection, but one just came up. The 
user fills in a form, and the submit calls a Python script that formats 
the data and passes it to the Z SQL Method that contains the INSERT INTO 
command. The only data access is this single INSERT command, and it 
succeeds, at least in the sense that the data is properly inserted into 
the table. But I get this ugly and hard to understand error message:

   <H2>Site Error</H2>
   <P>An error was encountered while publishing this resource.
   </P>
   <P><STRONG>_mysql_exceptions.NotSupportedError</STRONG></P>

   Sorry, a site error occurred.<p>

	OK, I get that something's wrong, but how do I go about figuring 
out the problem? I tried using the src__=1 trick to view the generated 
SQL statement, and that was fine: if I plugged it into a MySQL GUI 
interface, it ran without problem. And even running through Zope, the 
data does get properly inserted into the table. So what's up with this 
error message?
