even if you know beyond reasonable doubt that there isn't any more

Do you know for sure that will always be the case? It would seem easier to plan for it now and using an array than wait for a year, or five, only to realize that something changed in the design or usage of your code and now more rows are required. If it always returns one row, then looping over it with one row shouldn't cause any problems.

"Invalid cursor state" leads me to believe that there is a problem with performing two executes on a database in quick succession. Have you done any debugging between the two executes to rule out the obvious? For example, closing the connection and re-opening, or adding a sleep, or anything like that? I'm not an expert of using DBD, but I have done similiar things to what you're showing here and haven't run into this issue. 
my $sth = $dbh->prepare("INSERT INTO tblserverattributes(hostname,attr
+name,attrvalue) VALUES (?,?,?)");

        foreach $attr( keys %{$info{'DATA'}}) {
                $sth->execute($hostname,$attr,$info{'DATA'}->{$attr});
        }

The code above shows multiple executes on a single prepare, although it's set up a bit differently than what you've got.

I hope that helps.
