Magento SQL在多商店中使用正确的活动类别获取产品sku

Question

我正在获取产品sku，该产品在该产品的类别上显示在网站上。

输出：

+-------------+------------+
| sku         | category_n |
+-------------+------------+
|      855202 |      test1 |
|     87972_k |      test2 |
|      887997 |      test1 |
+-------------+------------+

我看过这些表：

catalog_category_product
catalog_product_entity
catalog_category_entity
catalog_category_entity_varchar

查询仅返回一个SKU就给我很多行，我得到了大约100条记录。我看不到哪一个是当前处于活动状态的正确类别。

SELECT
    * 
FROM
    "catalog_category_product" as ccp 
JOIN
    "catalog_product_entity" as cpe ON "cpe.entity_id" = "ccp.product_id"
JOIN  
    "catalog_category_entity" as cat ON "cat.entity_id" = "ccp.category_id"
JOIN 
    "catalog_category_entity_varchar" as cv on cat.entity_id = cv."entity_id"
