sql - Magento SQL 查询：获取所有“单独不可见”的简单产品

Question

我希望直接在 Magento 数据库上编写一个 SQL 查询，以获取所有具有“单独不可见”可见性属性的简单产品，我相信其值为 1。

有人能帮忙吗？到目前为止，我发现表中设置了可见性值

catalog_product_entity_int

但一直无法进一步进步。谢谢

没有 ORM有很多理由不这样做，所有这些都可能（或可能不）适用于您的需求（存储过滤器、从正确的表中读取数据等）。至少，您可以使用产品集合对象来构建您将运行的查询：

$coll = Mage::getModel('catalog/product')->getCollection();
$coll->addAttributeToFilter('visibility' , Mage_Catalog_Model_Product_Visibility::VISIBILITY_NOT_VISIBLE);
echo $coll->getSelect();

结果查询将如下所示：

SELECT `e`.*, IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) AS `visibility`
FROM `catalog_product_entity` AS `e`
INNER JOIN `catalog_product_entity_int` AS `at_visibility_default`
    ON (`at_visibility_default`.`entity_id` = `e`.`entity_id`)
    AND (`at_visibility_default`.`attribute_id` = '526')
    AND `at_visibility_default`.`store_id` = 0
LEFT JOIN `catalog_product_entity_int` AS `at_visibility` ON (`at_visibility`.`entity_id` = `e`.`entity_id`)
    AND (`at_visibility`.`attribute_id` = '526')
    AND (`at_visibility`.`store_id` = 1)
WHERE (IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) = '1')

我希望这可能未经测试。

$sql = "SELECT * FROM catalog_product_entity_int WHERE visibility=1";
$connection = Mage::getSingleton('core/resource')->getConnection('core_read');
foreach ($connection->fetchAll($sql) as $arraytest) {
    echo $arraytest['name'];
}
