   exit();
}

$query = "SELECT name, cno from hotel.customer ORDER BY name";

if ($result = maxdb_query($link, $query)) {

   /* Get field information for column 'cno' */
   $finfo = maxdb_fetch_field_direct($result, 1);
 
   printf("Name:     %s\n", $finfo->name);
   printf("Table:    %s\n", $finfo->table);
   printf("max. Len: %d\n", $finfo->max_length);
   printf("Flags:    %d\n", $finfo->flags);
   printf("Type:     %d\n", $finfo->type);

   maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);
