مساعدة في كود المسح

السلام عليكم ..

مشكلتي بسيطة ..

عندي اكثر من مفتاح اساسي في الجدول

وهم

room_code

from

to

لان اختيار الغرف او حجزها يعتمد علي التاريخ ايضا ولا يتكرر

ما اريد فعلة علي الكود التالي هو اضافة from و to علي الـ 'room_code'

اي عندما يمسح يمسح عندما 'room_code' = from = to

if ((isset($_GET['room_code'])) && ($_GET['room_code'] != "")) {
  $deleteSQL = sprintf("DELETE FROM tbl_rooms WHERE room_code=%s",
                       GetSQLValueString($_GET['room_code'], "text"));

الكود كامل

<?php require_once('Connections/GoldenCityTravel.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

if ((isset($_GET['room_code'])) && ($_GET['room_code'] != "")) {
  $deleteSQL = sprintf("DELETE FROM tbl_rooms WHERE room_code=%s",
                       GetSQLValueString($_GET['room_code'], "text")





					   );


  mysql_select_db($database_GoldenCityTravel, $GoldenCityTravel);
  $Result1 = mysql_query($deleteSQL, $GoldenCityTravel) or die(mysql_error());
}
  $deleteGoTo = "list_rooms.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";
    $deleteGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $deleteGoTo));
