Members of the Microsoft SQL Server fixed database role db_denydatareader are denied permission to see data from any user table in the database. For more information about adding members to a database role, see AddMember Method.
If TRUE, the user mapping the login authenticating the client application connection is a member of the db_denydatareader role.
