Adds a login as a member of a fixed server role.
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Use ALTER SERVER ROLE instead.
Applies to: SQL Server (SQL Server 2008 through current version).
When a login is added to a fixed server role, the login gains the permissions associated with that role.
The role membership of the sa login and public cannot be changed.
Use sp_addrolemember to add a member to a fixed database or user-defined role.
sp_addsrvrolemember cannot be executed within a user-defined transaction.
The following example adds the Windows login Corporate\HelenS to the sysadmin fixed server role.
EXEC sp_addsrvrolemember 'Corporate\HelenS', 'sysadmin'; GO
