Are you referring to GRANT ALTER ON objectname?
If so means that the user will be allowed to make changes on the object.
If a table then he can drop, add or modify columns.
If a view then he can change the view definition.
If a function or stored procedure he can change the code.

No, in sql server there is an 'alter settings' option you can grant  like Grant alter settings to [<prinsiple>]  the ssms screen shot of the property I am talking about. image attached.

I see. That means who have rights on ALTER SETTINGS can change any setting for the current SQL Server instance.
Basically you give permission to someone to execute the sp_configure.

reson I ask is we have not seen or noticed this option until we went to ssms 2014
Vitor MontalvãoMSSQL Senior EngineerCommented:
You can find that at least in SQL Server 2008R2. I don't have any previous version here so I can't confirm for SQL Server 2005.

ALTER SETTINGS

      Grants or denies the ability to execute sp_configure and change settings. Also grants or denies the ability to execute RECONFIGURE afterwards. This permissions is granted by default to members of the serveradmin and sysadmin fixed server role.

Found elsewhere. It's also a securable in SQL2005, but of course the client tools, especially management studio and drivers have to know and support this to see it there.

Bye, Olaf.
