Hi,
I see your point re:

>my $sth = $dbh->prepare ($query);
>$sth->execute();
># metadata information becomes available at this point ...
>printf "NUM_OF_FIELDS: %d\n", $sth->{NUM_OF_FIELDS};
>print "Note: query has no result set\n" if $sth->{NUM_OF_FIELDS} == 0;
but what I really want to do is determine at an early stage if I have any
results at all in my result set. Actual reason for this is that I'm doing a
SELECT WHERE query and scanning my entrire DB for a session ID that
matches one read from a cookie. I then want to determine if this is a valid
session id and if not re-direct the user to a page saying "unrecongnised
session id" or something.
Thanks,
Jeff
