i have worked with dkubb and here is how i interpret and boil it down:

  my $dbh =DBI->connect(
        "dbi:$dbidriver(RaiseError=>1,Taint=>1):dbname=$dbname;host=$d
+bhost", "$dbusername", "$dbpassword", );
   

    my $statement= "select name from names";
    my $sth = $dbh->prepare($statement);
    $sth->execute();

##grab all rows as array ref

    my $site = $sth->fetchall_arrayref;

    $sth->finish;

    $dbh->disconnect;

    my %stuff;

##push everything into a hash

    foreach my $site_in ( @{$site} ) {

        push @{ $stuff{view} },
          {       
            name => $site_in->[0], 
          };

    }
#load file
  my $template = HTML::Template->new(
        filename          => catfile( foo.tmpl ),
        die_on_bad_params => 0
    );
#load in hash
    $template->param( {%stuff} );
#print out
    print $template->output;

this is foo.tmpl:

<table>
<tr><td>name</td></tr>
<tmpl_loop name=view>

<tr>           
<td><tmpl_var name=name></td>
</tr>

</tmpl_loop>

sorry if anything catches n breaks, i had to pull a lot of this out of some subroutines i used to break up the workload
