调试Magento扩展中的SQL语法错误

我是Magento的新手，在调试最近安装的扩展时遇到了这个错误。我试图理解日志，但不知道到底是什么问题。有人能告诉我根据下面的日志从哪里开始调试吗

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AS `query_id`, `s`.`product_id`, MATCH (s.data_index) AGAINST ('' IN BOOLEAN MOD' at line 1

如果您有一个模型，它正在执行查询，并且您想知道将生成什么样的SQL，那么您有一些选择， 我最喜欢的是使用下面的

$collection = Mage::getModel('customcodes/code')->getCollection()
->addFieldToSelect('code')
->addFieldToFilter('order_id',array('eq'=>247938))
->addFieldToFilter('code_type',array('eq'=>'CODESQAC'));

$sql=$collection->getSelect（）->

然后，$sql就可以了

SELECT `main_table`.`code` FROM `custom_codes` AS `main_table` WHERE (`order_id` = 247938) AND (`code_type` = 'CODESQAC')

现在，您可以通过magnet语法来了解为什么它不会像您看到的那样拉取结果或抛出错误。 听起来您知道Magento代码的来源，因此使用此方法将帮助您确定它们使用的语法是否不正确

另外，检查代码中是否有硬编码的表名，而不是使用Magento工厂方法和/或调用特定的表名，而不是使用以下类似的方法来获取实际的表名（您可以有一个表名前缀，而原始代码可以是硬编码的）

下面是一个使用硬编码表名而不是使用配置来获取表名的示例（对于表名前缀）

$collection->getSelect()->joinLeft(array('sfoa'=>'sales_flat_order_address'), 'main_table.entity_id = sfoa.parent_id and sfoa.address_type = \'billing\'', array('sfoa.company'));

正确的方法应该是这样

$resource = Mage::getSingleton('core/resource');
$sales_table = $resource->getTableName('sales/order_address');

$collection->getSelect()->joinLeft(array('sfoa'=>$sales_table), 'main_table.entity_id = sfoa.parent_id and sfoa.address_type = \'billing\'', array('sfoa.company'));

希望这能帮助您检查错误的语法，并最终检查实际SQL的创建方式和内容

看看这个。

$resource = Mage::getSingleton('core/resource');
$sales_table = $resource->getTableName('sales/order_address');

$collection->getSelect()->joinLeft(array('sfoa'=>$sales_table), 'main_table.entity_id = sfoa.parent_id and sfoa.address_type = \'billing\'', array('sfoa.company'));
