将 SQL Server 2016 表移动到另一个数据库并使用原始名称使用同义词访问它

Question

For integration purposes I want to move a table to a different database B ( on the same server ) and then create a synonym of the table on the original database A so that all the objects referring to the table can still work as before the move. The problem I'm having is that to create the synonym I first have to delete the local table which It's not easy as it has several objects depending on it. Is there an easier way other than recreating ALL the depending objects to achieve this? In other words is there a way to "turn off the dependency check", drop the table, create the synonym and ... reactivate the dependencies which now find the synonym?

Hope it makes sense, thanks!

Answer 1

I'm afraid I have to drop this idea. Probably "converting" the table into a synonym could be done by first dropping all the foreign keys, deleting the table and then creating the synonym; after this views referring to the table would work fine reading data from the other database through the synonym BUT I could not recreate the foreign keys as I now learn that you can not create foreign keys on a synonym ( similarly Cross database foreign keys are not supported ). due to this my whole idea is not gonna work and I will have to look into merging the two databases.

For sake of details: the table contains user accounts which need to be shared between two systems using two different databases; both systems must be able to add, update and delete user accounts and both systems have several tables which are referring to user records and which need a way to check referral integrity, foreign keys are required.

thanks for the attention.
