Re: problem fetching currval of sequence

Tom,

Quite right, I did mean to do an INSERT. Changing the script to do
so though I still get the error:
ERROR: gb_gb_id_seq.currval is not yet defined in this session.

foreach $id(sort keys %ACCN) {
$conn->exec(
"INSERT INTO gb (clone_id,accn,gi)
VALUES ( '$ACCN{$id}{clone_id}','$ACCN{$id}{gb}','$ACCN{$id}{gi}')";
);

$result = $conn->exec("SELECT currval('gb_gb_id_seq');");
die $conn->errorMessage unless PGRES_TUPLES_OK eq
$result->resultStatus;
$gb_id = $result->fetchrow;
$ACCN{$id}{gb_id} = $gb_id;
}
