Hi,
I have a pice of code which does basiccaly this:
$query = "fetch in T";
while (($res = PQexec($PG_CONN, $query)) &&
($PGRES_TUPLES_OK == PQresultStatus($res)) &&
(PQntuples($res) == 1)) {
do_stuff();
PQclear($res);
}
As you see I'm still using the old perl-interface :).
Now, this worked splendidly at home. No problems whatsoever. At home I
have 6.3.2. Now I wanted to use the same piece of code in the production
environment (PG_VERSION contains 6.1, but I think it's really 6.2). The
damned thing fails.
But it's not like it doesn't run. It run's, only after fetching 3765
rows, PQresultStatus() returns 0, which is PGRES_EMPTY_QUERY.
If I do the sme things in psql (begin; declare T cursor...; ...; fetch in
T), I have no trouble at all 'walking by' this row.
And the damned thing is that I can't even test for this special case
(PGRES_EMPTY_QUERY) and then continue, cos it's considered an error, and
all queries are ignored till the end of the transaction.
Anybody knows what's going on here?
Maarten
