推荐答案

我能想到的最好方法是通过 sp_addlinkedserver .您需要确保使用任何帐户添加链接(通过 sp_addlinkedsrvlogin )有权访问您要加入的表，但是一旦链接建立，您就可以按名称调用服务器，即:

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 .....
