This document is applicable only to high-availability instances of RDS for SQL Server 2012 and later versions.

Currently, linked server creation has the following constraints:

  • You cannot create a linked server on the RDS console.
  • Creating a linked server with a series of storage procedures is complex.
  • You cannot create a linked server using DNS and the corresponding IP address.

Despite the constraints, this document provides a simple method of creating a linked server. 

DECLARE
        @linked_server_name sysname = N'my_link_server',
        @data_source sysname = N'***********', --style: 10.1.10.1,1433
        @user_name sysname = N'****' ,
        @password nvarchar(128) = N'**********',
        @link_server_options xml
        = N'
            <rds_linked_server>
                <config option="data access">true</config>
                <config option="rpc">true</config>
                <config option="rpc out">true</config>
            </rds_linked_server>

        EXEC sp_rds_add_linked_server
            @linked_server_name,
            @data_source,
            @user_name,
            @password,
            @link_server_options
