[Zope] Processing ZSQL results

11 Apr 2003

      Hi all,

I should know this, but here goes anyway.  I want to retrieve data from a table
if an id that is submitted from a form is present.  If I submit three id's, but
only two are present in the table, two results are returned.  I want to trap the
missing id and display a "no data found" message.  How can I do this?

<table>
<dtml-in getResults>
   <tr><td><dtml-var ID></td</tr>
<dtml-else>
  <tr><td>No Data</td></tr>
</dtml-in>

This shows only the two results.  The <dtml-else> is triggered only if none of
the three ID's are present.

Thanks,

Mark Evans
