[Zope] no data matching query

[Martin Hofer]

hi out there,

is it possible to test if a database-query returned data or not?
i'm not interested in the result - data, only if there where one or more
rows matching the query...

another simple question:
is there a more simple possibility to get only the first query-match than:

<dtml-in dataquery size=1 orphan=1>

...
</dtml-in>

thanx in advance!
