Load & Display 1 Row From DBI - Best Pract ice?

I'm using HTML::Template from CGI::Application.  My template is getting
data via a SQL query where exactly one row
retrieved, and it is displayed using <TMPL_LOOP>.

What is the proper way set & display values returned from DBI when only
one row is printed?  I think the method described below may have a
better alternative.
 

Currently showing all records using a loop:

1. $template->param(
2.  RESULTS => $self->dbh->selectall_arrayref('
3.    SELECT age, day FROM table WHERE id = ?',
4.    { Slice => {} },
5.    $self->session->param('id') )
6. );


Template:

1. <TMPL_LOOP NAME="RESULTS">
2.   <TMPL_VAR NAME="age"><TMPL_VAR NAME="day">
3. </TMPL_LOOP>


-Thanks
