[Zope] Direct SQL-Method traversal

[Stefan Bund]

I have implemented a simple ZSQL-Method (fetch) which takes one argument, a
record number (nr). As far as I understand the ZSQL Manual, I should
be able to write URL's of the form

fetch/nr/<number>/showit

where showit is a DTML-Document which can access the result of the
fetch query. How do I access this result?  I tried to use the column
names (like <!--#var shortname-->, where shortname is a result column
name), but Zope gave me a Key Error. What is the correct syntax to
access the result columns of such a query?

Stefan.
