Creating a link between two SQL servers

To create a link between two SQL Servers you need to use the sp_addlinkedserver and sp_addlinkedsrvlogin stored procedures.

First,

sp_addlinkedserver @server='DBLINK01',@srvproduct='',@provider='SQLOLEDB',@datasrc='SQL-HOU-01';

Where,
@server is the name of the link
@srvproduct is the type of product, by default SQL Server
@datasrc is the server you link to

Then, you need to set the username and password to use on the link.

sp_addlinkedsrvlogin 'DBLINK01','false',null,'sa','Pa$$w0rd';

The first parameter is the name of the link to use,
The fourth is the account of the remote server to use,
The fifth is the password for the account.
