ここに詳細テーブルから削除しようとしています。詳細テーブルに3つのレコードがあり、詳細テーブルから1つのレコードを削除するだけではなく、他の2つのレコードにも影響しません在庫表で.. 唯一の最初のレコードをこのコードの動作正しく、それはディテール表から削除クエリのためでは動作しないと在庫表で行わないことに...ここで

<?php 
include("include/config.inc.php"); 


$purchaseMasterId = isset($_REQUEST['purchaseMasterId']) ? $_REQUEST['purchaseMasterId'] : 0; 

if($purchaseMasterId > 0) { 
    $k = 0; 
    $selectMaster = "SELECT purchasedetail.purchaseMasterId, colorId, 
          totalkg, purchaseDetailId, partyId 
        FROM purchasedetail 
         JOIN purchasemaster ON 
          purchaseMaster.purchaseMasterId = purchasedetail.purchaseMasterId 
        WHERE purchasedetail.purchaseMasterId = ".$_REQUEST['purchaseMasterId']; 

    $selectMasterRes = mysql_query($selectMaster); 
    while($purRow = mysql_fetch_array($selectMasterRes)) { 
     $purchaseDetailId = $purRow['purchaseDetailId']; 
     $purchaseMasterId = $purRow['purchaseMasterId']; 
     $colorId   = $purRow['colorId'];
