Subject: [PATCH] Database: Add missing `AS` after `INNER JOIN` in some
 queries.

While `AS` is an optional keyword in SQL, it is commonly considered best practice to include it for better readability and compatibility. This also makes the queries more consistent with other queries using aliases in core.

Follow-up to [6359], [30238].

Props costdev, domainsupport.
Fixes #54769.
