/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$query = "SELECT * FROM DUAL";
/* execute multi query */
if (maxdb_multi_query($link, $query)) {
do {
/* store first result set */
if ($result = maxdb_use_result($link)) {
while ($row = maxdb_fetch_row($result)) {
printf("%s\n", $row[0]);
}
maxdb_free_result($result);
}
/* print divider */
if (maxdb_more_results($link)) {
printf("-----------------\n");
}
} while (maxdb_next_result($link));
}
/* close connection */
maxdb_close($link);
