$grace=20;
$conn = ociLogon('username', 'pwd','host');
if (!$conn) {
$e = ocierror();
print htmlentities($e['message']);
exit;
$query = "udpate product set status_dtm = (status_dtm)+20 where product_no = $quantity";
$stid = ociparse($conn, $query);
if (!$stid) {
$e = ocierror($conn);
print htmlentities($e['message']);
exit;
$r = ociexecute($stid, OCI_DEFAULT);
if (!$r) {
$e = ocierror($stid);
echo htmlentities($e['message']);
exit;
print '<table border="1">';
while (ocifetchinto($stid, $row, OCI_ASSOC)) {
print '<tr>';
     foreach ($row as $item) {
print '<td>'.($item?htmlentities($item):' ').'</td>';
print '</tr>';

Answer 1

$query = "udpate product set status_dtm =
(status_dtm)+20 where product_no = $quantity";It says "udpate" instead of "update" :-)
