我有一个保存产品信息的 SQL 数据库，包括产品的名称和描述。

它目前的设置方式是这样的：

+-------------+-------------+------------------+--------------------------------+
| products_id | language_id | products_name    | products_description           |

+-------------+-------------+------------------+--------------------------------+

products_description当它相同products_id但不同时，它想通过并找出不同的地方language_id。（1 应该是英语，2 应该是德语）。如果我对此运行查询，我希望有一个简单的方法来找到 CONE DRIVE WORM REDUCER/KEGELRÄDER WORM REDUCER（所以product_idor product_name）。

我将如何使用 mysql 执行此操作？我真的不习惯做很多数据库的事情，但我需要找出这些产品中的任何一个是否得到了适当的处理。

试试这个：

SELECT DISTINCT products_id
FROM products_table -- assumed
GROUP BY products_description
  HAVING COUNT(products_id) > 1

应该为您提供一个结果，其中包含已翻译其描述的产品的产品 ID。如果您决定要使用未翻译其描述的产品的 ID，请将子句>中的测试替换为.HAVING=
