This took me a while, and brought me to some new dark corners of XS code :)

No, you do not need Dumper. In fact, you should never need Dumper. Data::Dumper is for debugging, not for production code. But that aside. The code I showed you should have worked from the perl side of view. $sth->{NAME_lc} returns a reference to a list, but in this case, as it is a statement handle from DBI, it is not a plain reference, but a reference with magig attached, and Text::CSV_XS cannot deal with that (yet). So the solution might be:

$csv->print (*STDOUT, [@{$sth->{NAME_lc}}]);

Which dereferences the reference to a list, and puting it back in an anonymous array again. That line would deserve some comment in production code :)

So, your final code should look like this:

my $csv = Text::CSV_XS->new ({ binary => 1, eol => "\r\n" });
$csv->print (*STDOUT, [@{$_read_sth->{NAME}}]);
while (my $row = $_read_sth->fetchall_arrayref) {
    # If you need to add other headers ...
    $csv->print (*STDOUT, [qw( some different header )]) if $needed;
    # print the data fetched
    $csv->print (*STDOUT, $row);  
    }
