You get a "Shared.DC.ZRDB.Results.Results" object.
It behaves like a list of rows representing your query result.
Each row behave like an object the attributes of which are
the columns of your query.

Use something like:

    <dtml-let ticket=maxTicketNumQuery> <!-- this calls your method! -->
      ....
      <dtml-var "ticket[0].NUM"> <!-- assumed: select max(*) as NUM ... -->
      ....
    </dtml-let>
