Hello ???,

it would be nice if you included your real name in your e-mails. Have you 
looked at the ZPT documentation? It should be quite straightforward to do 
what you want but you might want to think more carefully about what that is 
and how you want it to work. The current script would seem to produce a not 
particularly helpful result and as it doesn't contain any HTML is not 
really appropriate for ZPT.

A few pointers: 
you can use Python within ZPT to get at Zope Objects
<body tal:define="results python: here.test_select();
dicts python:results.dictionaries();
keys python:results.names()">

<div tal:repeat="record dicts">
<br tal:content="record">
<span tal:repeat="key keys" tal:content="python: record[key]">
</span>
</div>
</body>

This is untested and probably flawed - it's just supposed to help.

ZPT is really about predictable layouts so having completely dynamic result 
sets is not really the best way to use it. It is however, possible as far 
as I know.
