   exit();
}

$query "SELECT name, zip FROM hotel.city ORDER BY name";
if (
$stmt maxdb_prepare($link$query)) {

   
/* execute query */
   
maxdb_stmt_execute($stmt);

   
/* bind result variables */
   
maxdb_stmt_bind_result($stmt$name$code);

   
/* store result */
   
maxdb_stmt_store_result($stmt);

   
/* seek to row no. 5 */
   
maxdb_stmt_data_seek($stmt5);

   
/* fetch values */
   
maxdb_stmt_fetch($stmt);

   
printf ("City: %s  Zip: %s\n"$name$code);

   
/* close statement */
   
maxdb_stmt_close($stmt);
}
