I've gotta be missing something or smoking too much crack.
Well, I don't really find that beaming up effects my coding adversely, so my guess is that you're missing something.
Just a hunch, but I bet you have newlines attached to the values in
@usercodelist. FWIW, you ought to prepare that statement once with a placeholder, and repeatedly execute it.
Try this:
my $SQL = "UPDATE mytable SET subscribed = '0',
unsubscribedby = 'SYSTEM'
WHERE usercode = ? AND unsubscribedby = ''";
my $sth = $DBH->prepare( $SQL );
foreach my $md5 ( @usercodelist ) {
chomp $md5; # I'm assuming a newlines is bungling your update
$sth->execute( $md5 ) or die "Can't execute $SQL";
}
