It looks to me that you cut & pasted a bit to place the code in this node, but just to double check... You should only call ->disconnect() once. In DBI, you do...


$dbh = DBI->connect();

$dbh->do();
$sth = $dbh->prepare();
$sth->execute();
# And other methods for dealing with your data

$dbh->commit() or $dbh->rollback();

$dbh->disconnect();

In the code snippets you provided, you have a ->disconnect() after every ->do(). The other thing is that you seem to be using undef to mean a NULL. I am not sure if you can do that with placeholders. Just for kicks, try using '' (empty string) instead of undef and let us know.

Update: I just noticed that I gave out bad advice. The undef does not stand for a NULL but for an empty \%attr. Sorry for that.

Best regards
