About your code. Did you slap on 'use strict;' afterwards?
Your code doesn't compile under strict. You have two undeclared variables
($sth and @row).

You have a NULL value somewhere in your fetched record. Perl translates
this to undef, so one of the elements in @row is undef. Hence the
uninitialized value (print "@row" is essentially a 'print join " ",
@row;')

'dump_results' needs to fetch records behind the scenes, so you have to
execute your statement handle again, because you already exhausted it in
your while-loop.
