Question

假设我有一个类似的集合：

$products = Mage::getModel('catalog/product')
            ->getCollection()
            ...
            ->load();

如何打印执行的实际MySQL代码？

Answer 1

您可以随时通过回显getSelect来查看您的SQL查询，如下所示：

$products = Mage::getModel('catalog/product')
        ->getCollection();
echo $products->getSelect();

要更改查询参数，请查看以下方法：

$products->addAttributeToSelect('someattribute');
$products->addAttributeToFilter('someattribute', array('eq'=>'1'));

Answer 2

您可以使用以下代码打印集合：我们可以使用getSelect()->__toString()

打印集合查询

$products = Mage::getModel(‘catalog/product’)
 ->addAttributeToFilter(‘status’, array(‘eq’ => 1));
echo $products->getSelect()->__toString();

你见过http://kuldipchudasama.wordpress.com/2012/07/16/magento-print-query-of-collection/吗？这很有效。

Answer 3

此处的大多数其他答案都表示$products->getSelect()会这样做 - 如果您要处理的只是echo，这很好，但事实上getSelect()没有＆＃ 39; t只返回一个字符串，它返回一个Varien_Db_Select对象。

在该对象上调用echo会自动触发其__toString()方法，因此您只需获取SQL字符串，但尝试将其传递给Mage::log()，您将获得更多比你预期的要好。

如果您只想记录SQL，可以使用：

Mage::log($products->getSelect()->__toString());

或者如何使用对象自己：

$products->printLogQuery(false, true); // don't echo, do log

printLogQuery在lib / Varien / Data / Collection / Db.php中定义。

Answer 4

您可以打印

$products->getSelect()->assemble();

Answer 5

如果你简单地将->load()的第一个参数设置为true，就像这样：

$products = Mage::getModel('catalog/product')
            ->getCollection()
            ...
           ->load(true);

Answer 6

我每天都在收藏品。毫无疑问，这是正确的方法。

echo $collection->getSelectSql(true);

Answer 7

步骤1-

$result_colletion = print_r($collection->getSelect()); 
Mage::log($$result_colletion, null, custom_collection.log,true);

第2步

之后登录magento admin部分并启用日志设置。请参阅下文。

System > Configuration > Developer > Log Settings

第3步 -

之后，请参阅custom_collection.log文件夹中的日志文件var/log/。

Answer 8

在Magento 2中： -

namespace <Company>\<Module>\Block\Adminhtml\Tab\Log;
class Grid 
extends \Magento\Backend\Block\Widget\Grid\Extended
{

    protected $_collectionFactory;

    /**
     * Constructor
     *
     * @param \Magento\Backend\Block\Template\Context $context
     * @param \Magento\Backend\Helper\Data $backendHelper
     * @param \<Company>\<Module>\Model\ResourceModel\Log\CollectionFactory $collectionFactory
     * @param Psr\Log\LoggerInterface $logger
     * @param array $data
     */
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,
        \<Company>\<Module>\Model\ResourceModel\Log\CollectionFactory $collectionFactory,
        \Psr\Log\LoggerInterface $logger,
        array $data = []
    ) {
        $this->_logger = $logger;
        $this->_collectionFactory = $collectionFactory;
        parent::__construct($context, $backendHelper, $data);
    }

    /**
     * {@inheritdoc}
     */
    protected function _prepareCollection()
    {
        $collection = $this->_collectionFactory->create();
        $this->_logger->info($collection->getSelect()->__toString());
        $this->setCollection($collection);
        return parent::_prepareCollection();
    }
}

请记住，收集工厂是一个魔法类，可以附加到每个类，因为Magento 1不够复杂。

Answer 9

尝试以下代码。

 $products = Mage::getModel('catalog/product')
                ->getCollection();

    echo $products->getSelect();

$ collection =“Sql Query Here”;
echo $ collection-＆gt; getSelect（） - ＆gt; __ toString（）;
