如何将MySql查询转换为Magento集合：

我试图表明，哪个产品的产品价格低于50％的最终价格应该显示在网页上。

我试过下面的查询在MySql中运行正常，工作正常，我需要转换为Magento集合格式。

SELECT `e`.*, `at_category_id`.`category_id`, IF(at_status.value_id > 0, at_status.value, at_status_default.value) AS `status`, IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) AS `visibility`, `at_special_price`.`value` AS `special_price`, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price` FROM `catalog_product_entity` AS `e`
 LEFT JOIN `catalog_category_product` AS `at_category_id` ON (at_category_id.`product_id`=e.entity_id)
 INNER JOIN `catalog_product_entity_int` AS `at_status_default` ON (`at_status_default`.`entity_id` = `e`.`entity_id`) AND (`at_status_default`.`attribute_id` = '273') AND `at_status_default`.`store_id` = 0
 LEFT JOIN `catalog_product_entity_int` AS `at_status` ON (`at_status`.`entity_id` = `e`.`entity_id`) AND (`at_status`.`attribute_id` = '273') AND (`at_status`.`store_id` = 1)
 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)
 INNER JOIN `catalog_product_entity_decimal` AS `at_special_price` ON (`at_special_price`.`entity_id` = `e`.`entity_id`) AND (`at_special_price`.`attribute_id` = '567') AND (`at_special_price`.`store_id` = 0) 
 INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0 WHERE (IF(at_status.value_id > 0, at_status.value, at_status_default.value) = '1') AND (IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) = '4') AND (at_special_price.value != '') AND (at_category_id.category_id = '35') and price_index.final_price < (price_index.price * .5)

试试这个：

$select = "
    SELECT `e`.*, `at_category_id`.`category_id`, IF(at_status.value_id > 0, at_status.value, at_status_default.value) AS `status`, IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) AS `visibility`, `at_special_price`.`value` AS `special_price`, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price` FROM `catalog_product_entity` AS `e`
 LEFT JOIN `catalog_category_product` AS `at_category_id` ON (at_category_id.`product_id`=e.entity_id)
 INNER JOIN `catalog_product_entity_int` AS `at_status_default` ON (`at_status_default`.`entity_id` = `e`.`entity_id`) AND (`at_status_default`.`attribute_id` = '273') AND `at_status_default`.`store_id` = 0
 LEFT JOIN `catalog_product_entity_int` AS `at_status` ON (`at_status`.`entity_id` = `e`.`entity_id`) AND (`at_status`.`attribute_id` = '273') AND (`at_status`.`store_id` = 1)
 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)
 INNER JOIN `catalog_product_entity_decimal` AS `at_special_price` ON (`at_special_price`.`entity_id` = `e`.`entity_id`) AND (`at_special_price`.`attribute_id` = '567') AND (`at_special_price`.`store_id` = 0) 
 INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0 WHERE (IF(at_status.value_id > 0, at_status.value, at_status_default.value) = '1') AND (IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) = '4') AND (at_special_price.value != '') AND (at_category_id.category_id = '35') and price_index.final_price < (price_index.price * .5)
";

$collection = new Mage_Mymodule_Model_Mysql4_Collection();
$collection->load($select);

记得将Mage_Mymodule_Model_Mysql4_Collection更改为模块集合类或默认核心集合类

MySql转换为Magento集合格式
