FK / PK relationships across databases?
Posted on 2013-01-14
I have an MS SQL 2008 R2 instance. There are 3 databases; I will say db_1, db_2 and db_3. I want db_2 to hold all the common information like users, email addresses, and some other metadata, then the other 2 db's will be for 2 separate front end transactional applications. Is there a way to enforce PK / FK constraints across databases in the same MS SQL server instance?
