I don't think that this code will work for you. It returns an sql database
handle, so I don't know that this will work with a gdbm database.

Although, I was looking through some of the new 4.8 docs 
(found at http://developer.akopia.com/cgi-bin/ic/dev-4.8/ictags)

and thought that you could probably use the query tag. Here is what the docs
say:

 my $sql = "select * from products order by price";
   my $result_array = $Tag->query( { sql => $sql,  },
                                   $body );
   my ($same_results, $col_name_hash, $col_name_array) =
                      $Tag->query( { sql => $sql,  },
                                   $body );

   my $result_hasharray = $Tag->query( { sql     => $sql,
                                         hashref => 'my_results',  },
                                       $body );

or similarly with positional parameters,

$Tag->query( $sql, $attribute_hash_reference, $body);

Doing your query like this should work.
