Result set

Column name Data type Description
Data Source Name sysname Name of the data source.
Description varchar(255) Description of the data source.
Type int Type of data source:

1 = ODBC DSN
3 = OLE DB data source
Provider Name varchar(255) Name of the OLE DB provider. Value is NULL for ODBC DSN.

Remarks

Every SQL Server service has a user context. A user context is a set of Registry entries that includes the definitions of the ODBC data sources for the user. The user context is provided by the username under which the SQL Server is running.

For example, if the server is running under the system account user context, the data source names (DSNs) that are returned are all system DSNs that are associated with the system account. If the server is running under a private user account, only the DSNs defined for that private account of that user is returned.

Permissions

Only members of the sysadmin fixed server role can execute sp_enumdsn.
