I'm not understanding what you are trying to do here - why
would you create a new database connection for each user?

In Zope, you usually only need to add a single db connection
object (by using "Add" in the management interface, not through
code). Then you Add Z SQL Method objects, which encapsulate the
various queries you want to run. The SQL Method objects just use
the existing database connection.

If you need to trap an exception, you should probably use an
External Method - DTML does not let you handle exceptions 
directly.

Hope this helps!
