Comments

SQL Server linked servers are OLE DB data sources that can be referenced using four-part names in distributed queries. SQLLinkedServers returns the properties defining the data source as a result set. Linked servers are defined to SQL Server using the sp_addlinkedserver system stored procedure. The columns of the result set are defined as follows.

SQLWCHAR

Product name for this linked server.

SRV_DATASOURCE

Provider-specific string that identifies the source of the data.

SRV_LOCATION

6

SQLWCHAR

Location argument that identifies the database to this provider.

SRV_CAT

7

SQLWCHAR

Name of the catalog containing the data on the linked server.

SRV_PROVIDERSTRING is NULL when the SRV_DATASOURCE and SRV_CAT information is sufficient to identify the source of the data to the provider.

When the linked server is a server running an instance of SQL Server, SRV_DATASOURCE is the name of the server, SRV_CATALOG is the name of the database, and SRV_LOCATION is NULL.
