I use this code for executing db queries like so. I am now getting the error can't call method prepare on undefined value. How an this be when I define $dbh on the line before the prepare? Is there a better way to do this in General?
my $query = "SELECT id FROM table WHERE user=$user";

    my $results=$self->query($query)->fetchrow_array;

    $sth->execute();
    return $sth;
}##END query
