Php Magento升级，从1.4.0.2到1.7.0.2的层价格出现错误

获取以下错误：

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`catalog_product_entity_tier_price`, CONSTRAINT `FK_6E08D719F0501DD1D8E6D4EFF2511C85` FOREIGN KEY (`customer_group_id`) REFERENCES `customer_group` (`customer_group_id`) ON DEL)

我不知道如何解决这个问题。有什么帮助吗

当我检查数据库时，customer_组有四行，就像任何其他magento安装一样，其中as catalog_product_entity_tier_price完全为空

客户组表转储：

 CREATE TABLE IF NOT EXISTS `customer_group` (
 `customer_group_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Customer Group Id',
 `customer_group_code` varchar(32) NOT NULL COMMENT 'Customer Group Code',
 `tax_class_id` int(10) unsigned NOT NULL DEFAULT '0' COMMENT 'Tax Class Id',
  PRIMARY KEY (`customer_group_id`)
  ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COMMENT='Customer Group' AUTO_INCREMENT=5 ;

--
-- Dumping data for table `customer_group`
--

INSERT INTO `customer_group` (`customer_group_id`, `customer_group_code`, `tax_class_id`) VALUES
(1, 'General', 3),
(2, 'Wholesale', 3),
(3, 'Retailer', 3),
(4, 'NOT LOGGED IN', 3);

目录\产品\实体\层级\价格转储：

请帮我解决这个问题。（使用magento 1.7.0.2）

谢谢。

好的，挖了一个多小时后，我找到了原因

在

customer\u group表中

，

未登录

组

customer\u group\u id

必须为0。但在这个表中，是4导致了这个问题

将id更改为0后，它现在可以正常工作
