SQL Server 2005: how to add a linked server

 

 

A linked server is a virtual server that has been defined to SQL Server 2005 with all the information required to access an OLE DB data source. A linked server name is defined by using the sp_addlinkedserver system stored procedure.

EXEC sp_addlinkedserver

       @server=’SERVER_NAME’

       @srvproduct=’’

       @provider=’SQLNCLI’

       @datasrc=’SERVER_NAME’

 

Local SQL Server logins are mapped to logins in the linked server by using sp_addlinkedsrvlogin.

The SQL Script below connects a specific login to the linked server by using different user credentials

EXEC sp_addlinkedsrvlogin 'REMOTE_SERVER_NAME', 'false', 'LOCAL USERID', 'REMOTE USERID', 'REMOTE PASSWORD'

 

The sp_serveroption system stored procedure is used to set server options for remote servers and linked servers. The SQL script below enables a linked server for distributed query access, which can be used only for sys.server entries added through sp_addlinkedserver.

EXEC sp_serveroption ‘REMOTE_SERVER_NAME’, ‘data access’, ‘true’

 

sp_linkedservers
 -- Returns the list of linked servers defined in the local server.
