Not all DBDs set the statement handle before a fetch, but MySQL does. That means that you don't have to fetch *any* rows. For a purposefully verbose example: 
if (my $rows = $sth->execute) {
    if ($rows==0) {
        print "Zero rows returned";
    }
    else {
        print "$rows rows returned";
    }
}
else {
   print "Failed execute: ". $sth->errstr;
}
$sth->finish;

Note that the finish() is required here because you do no fetching. If one of the if's had a fetch, you'd omit the finish().
