Selecting data from two different servers in SQL Server

Question

How can I select data in the same query from two different databases that are on two different servers in SQL Server?

Answer 1

Simplified solution for adding linked servers

First server

EXEC sp_addlinkedserver @server='ip,port\instancename'

Second Login

EXEC sp_addlinkedsrvlogin 'ip,port\instancename', 'false', NULL, 'remote_db_loginname', 'remote_db_pass'

Execute queries from linked to local db

INSERT INTO Tbl (Col1, Col2, Col3)
SELECT Col1, Col2, Col3
FROM [ip,port\instancename].[linkedDBName].[linkedTblSchema].[linkedTblName]
