Sql 使用左联接和分组依据时显示第二个子表值

我有三个表类别、产品和Sku，它们有父子关系

我想要第一个产品记录，其中产品id的所有sku必须与sku表中的产品id相匹配，而类别id的所有产品必须与产品表中的类别id相匹配

现在这里的问题是我想在这里显示sku id和类别id。有可能吗

以下是查询：

SELECT cat.category_id FROM Category cat
LEFT JOIN(
  SELECT product.product_id
  FROM Product product
  LEFT JOIN Sku sku ON product.sku_id = sku.sku_details_id
  GROUP BY product.product_id
  HAVING COUNT(product.product_id) = COUNT(sku.sku_details_id)
  ) childProduct ON cat.product_id = childProduct.product_id
  GROUP BY cat.category_id
  HAVING COUNT(cat.category_id) = COUNT(childProduct.product_id)

样本数据

结果应该是

请从表中发布一些记录also@HiteshRakhadia，不客气。如果你发现这个答案很有用并且解决了你的问题，那么接受这个答案。这将帮助某人。嗨，我得到了sku id，但我也得到了不必要的类别id。因为如果我按值添加另一个组，那么得到的结果是change@HiteshRakhadia，检查更新的答案。希望这是你想要的。@HiteshRakhadia，你检查了吗。它是否有用？
