sp_addlinkedserver [@server =] ' server ' [,] [@srvproduct =] ' product_name ']
[, ] [@provider =] ' Provider_name '] [,] [@datasrc =] ' data_source ']
[, ] [@location =] ' Location '] [,] [@provstr =] ' provider_string ']
[, ] [@catalog =] ' Catalog ']
This storage process has seven parameters, the meaning of which is as follows:
Server: The name of the connection to establish.
Srvproduct: The product name for the data source to which you want to connect. This parameter defaults to NULL.
Provider: Unique identifier of the product for the data source to which you want to connect. In the Hkey_local_machinesoftwaremicrosoftmssqlserverproviders entry in the registry, you have the name of all connection data types supported by the local server.
DATASRC: As an explanatory information for this data source. This parameter defaults to NULL.
Location: An explanation for the location of this data source. This parameter defaults to NULL.
PROVSTR: The connection string for this data source. This parameter defaults to NULL.
