That piece of code is returning only the last id. How to get all ids using it?

I have changed it for the below code but now it is returning only the first element. Can you help me, please?

if ($id[0] eq "")
{   
    my $sql = "SELECT DISTINCT id FROM mytable WHERE active = ?";
    $id[0] =  @{$dbh->selectall_arrayref($sql,undef,'no')};
    #@id = map{ $_->[0] } @$ref;
    print join (", ", @id), "\n";
}
