How can I join two tables, which are located two different SQL Server instances, in one query?
Solution
The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:
SELECT *
FROM server1table
INNER JOIN server2.database.dbo.server2table ON .....
OTHER TIPS
You can create a linked server and reference the table in the other instance using its fully qualified Server.Catalog.Schema.Table name.
If you are using SQL Server try Linked Server
