如何从Magento中删除所有相关的产品链接？

我创建导入脚本来管理相关产品，并使用如下代码：

$product = Mage::getModel('catalog/product')->load($product_id);
$related_data = array();
related_data[$linked_product_id]['position']=1;
$product->setRelatedLinkData($related_data);
$product->save();

SQLSTATE[23000]: Integrity constraint violation: 1452
Cannot add or update a child row: a foreign key constraint fails
(`netztech`.`catalog_product_link`, CONSTRAINT
`FK_CAT_PRD_LNK_LNKED_PRD_ID_CAT_PRD_ENTT_ENTT_ID`
FOREIGN KEY (`linked_product_id`)
REFERENCES `catalog_product_entity` (`entity_id`) ON DELETE C)

 $connection = Mage::getSingleton('core/resource')->getConnection('core_write');
 $sql = "DELETE FROM `catalog_product_link` WHERE `link_type_id`=1";
 $connection->query($sql);

我得到的错误如下：

$product = Mage::getModel('catalog/product')->load($product_id);
$related_data = array();
related_data[$linked_product_id]['position']=1;
$product->setRelatedLinkData($related_data);
$product->save();

SQLSTATE[23000]: Integrity constraint violation: 1452
Cannot add or update a child row: a foreign key constraint fails
(`netztech`.`catalog_product_link`, CONSTRAINT
`FK_CAT_PRD_LNK_LNKED_PRD_ID_CAT_PRD_ENTT_ENTT_ID`
FOREIGN KEY (`linked_product_id`)
REFERENCES `catalog_product_entity` (`entity_id`) ON DELETE C)

 $connection = Mage::getSingleton('core/resource')->getConnection('core_write');
 $sql = "DELETE FROM `catalog_product_link` WHERE `link_type_id`=1";
 $connection->query($sql);

如果要从商店中删除所有相关的产品链接，easist方法如下：

$product = Mage::getModel('catalog/product')->load($product_id);
$related_data = array();
related_data[$linked_product_id]['position']=1;
$product->setRelatedLinkData($related_data);
$product->save();

SQLSTATE[23000]: Integrity constraint violation: 1452
Cannot add or update a child row: a foreign key constraint fails
(`netztech`.`catalog_product_link`, CONSTRAINT
`FK_CAT_PRD_LNK_LNKED_PRD_ID_CAT_PRD_ENTT_ENTT_ID`
FOREIGN KEY (`linked_product_id`)
REFERENCES `catalog_product_entity` (`entity_id`) ON DELETE C)

 $connection = Mage::getSingleton('core/resource')->getConnection('core_write');
 $sql = "DELETE FROM `catalog_product_link` WHERE `link_type_id`=1";
 $connection->query($sql);

当然，首先在目录\产品\链接\类型表中检查相关产品的链接id。通常为1，但最好先检查

如何对一个产品执行此操作？只需像这样扩展sql：从

目录\u产品\u链接

中删除

链接\u类型\u id

=1和

产品\u id

=您的产品\u id
