MySQL：如何在1个条件下从2个不同的表中获取结果

Question

I have 2 tables with different content and there is no way to join tables because there is no common identifier, but every table as 1 column with same content. I need to extract the content from these both colums and want to get ID's from each record that is the same. The following query extracts what I already know/have, but I don't get the ID's from the WHERE IN table.

Query

SELECT pd.products_id, pd.products_short_description 
FROM products_description pd
WHERE pd.products_short_description IN (SELECT m.manufacturers_ean FROM manufacturers m)

Result

ID | products_short_description
-------------------------------
2  | BMW

This is what I need:

ID | products_short_description | ID | manufacturers_ean
--------------------------------------------------------
2  | BMW                        | 285| BMW

FROM products_description pd
INNER JOIN manufacturers m on m.manufacturers_ean  = pd.products_short_description
