if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

$maxdb->query("CREATE TABLE temp.t1 LIKE hotel.city");

/* INSERT INTO .. SELECT */
$maxdb->query("INSERT INTO temp.t1 SELECT * FROM hotel.city");
printf("%s\n", $maxdb->info);

/* close connection */
$maxdb->close();
?>

   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

maxdb_query($link, "CREATE TABLE temp.t1 LIKE hotel.city");

/* INSERT INTO .. SELECT */
maxdb_query($link, "INSERT INTO temp.t1 SELECT * FROM hotel.city");
printf("%s\n", maxdb_info($link));

/* close connection */
