Sorry for the long message, but there's a lot of context. I've tried
to factor the problem out and then provide supporting stuff for the
interested. Zope 2.7.6, Python 2.4.1 (Python 2.3.5 behaves in the same
In summary, the problem is that a query run as a test from the ZMI of
select * from <dtml-var udb>.tablename
fails on the second batch whereas
select * from foo.tablename
works fine for all batches.
The relevant Zope code distributed with Zope 2.7.6-final had a bug in
it which was discussed earlier on the list. The distributed code did
not terminate batching properly. The problematic code was in
and the fix was to patch the two link expressions to have a missing
element, that is,
<a href="&dtml-URL;?query_start=&dtml-next-sequence-start-number; \
&query=<dtml-var query url_quote missing="">">
which seemed to resolve the problem.
BUT, there is now a second problem. When the query is dynamic, the
second batch fails on a key error -- for the example above, it would
fail with a
> Z SQL Method at /testfolder/batchcheck External Editor
> Error, exceptions.KeyError: 'udb' SQL used:
> Could not render the query template!
message in the ZMI. However, REQUEST has the proper value for the key
according to the Error Log:
It's pretty clear that the query is being passed as an empty string due
to the key error. Presumably the query should be rendered and saved in
a persistent manner throughout the batching process. It is not clear
to me where this should be done. Any help in localizing and fixing the
problem would be appreciated.
