Remarks

Fixed server roles are defined at the server level and have permissions to perform specific server-level administrative activities. Fixed server roles can't be added, removed, or changed.

To add or removed members from server roles, see ALTER SERVER ROLE.

All logins are a member of public. sp_helpsrvrole doesn't recognize the public role because, internally, SQL Server doesn't implement public as a role.

sp_helpsrvrole doesn't take a user-defined server role as an argument. To list the user-defined server roles, see the examples in ALTER SERVER ROLE.

Permissions

Requires membership in the public role.
