Answer 1

I believe this should accomplish what you want, but as it will change data be sure to do a backup to ensure you can undo the changes if they're incorrect. Also, since you didn't specify the table names I assumed they're named locations and detail which is probably incorrect so you'll have to adjust the names.

UPDATE detail
SET location = locations.GeminiStoreID
FROM detail
INNER JOIN locations ON locations.AnimalStoreID = detail.location
