Re: [Zope] Finding out how many rows is selected in database

5 Apr 2001

      Use some variation on this:
Assume the query method is called "query1"

<!-- Execute the query -->
<dtml-let results=query1>
   <!-- display the number of rows -->
    There are <dtml-var "_.len(results)"> rows in the results.
</dtml-let>

In your case, you would probably want to assign the number of rows to a
variable - maybe with dtml-let - and use  it in a dtml-if element.
