[!INCLUDE SQL Server]
Grants permissions on system objects such as system stored procedures, extended stored procedures, functions, and views.

GRANT { SELECT | EXECUTE } ON [ sys. ] system_object TO principal
[ ; ]
The sys qualifier is required only when you're referring to catalog views and dynamic management views.
Specifies the object on which permission is being granted.
Specifies the principal to which the permission is being granted.
This statement can be used to grant permissions on certain stored procedures, extended stored procedures, table-valued functions, scalar functions, views, catalog views, compatibility views, INFORMATION_SCHEMA views, dynamic management views, and system tables that are installed by [!INCLUDE ssNoVersion]. Each of these system objects exists as a unique record in the resource database of the server (mssqlsystemresource). The resource database is read-only. A link to the object is exposed as a record in the sys schema of every database. Permission to execute or select a system object can be granted, denied, and revoked.
Granting permission to execute or select an object doesn't necessarily convey all the permissions required to use the object. Most objects perform operations for which extra permissions are required. For example, a user that is granted EXECUTE permission on sp_addlinkedserver can't create a linked server unless the user is also a member of the sysadmin fixed server role.
Default name resolution resolves unqualified procedure names to the resource database. Therefore, the sys qualifier is only required when you're specifying catalog views and dynamic management views.
Granting permissions on triggers and on columns of system objects isn't supported.
Permissions on system objects are preserved during upgrades of [!INCLUDE ssNoVersion].
You must be in the master database to grant permissions, and the principal you grant the permissions to must be a user in the master database. That is, if they're server-level permissions, you can't grant them to server principals, only database principals.
System objects are visible in the sys.system_objects catalog view. The permissions on system objects are visible in the sys.database_permissions catalog view in the master database.
The following query returns information about permissions of system objects:
SELECT *
FROM master.sys.database_permissions AS dp
INNER JOIN sys.system_objects AS so
ON dp.major_id = so.object_id
WHERE dp.class = 1 AND so.parent_object_id = 0;
GORequires CONTROL SERVER permission.
The following example grants the [!INCLUDE ssNoVersion] login Sylvester1 permission to select a view that lists [!INCLUDE ssNoVersion] logins. The example then grants the extra permission that is required to view metadata on [!INCLUDE ssNoVersion] logins that the user doesn't own.
USE master;
GO
GRANT SELECT ON sys.sql_logins TO Sylvester1;
GRANT VIEW SERVER STATE to Sylvester1;
GOThe following example grants EXECUTE permission on xp_readmail to Sylvester1.
USE master;
GO
GRANT EXECUTE ON xp_readmail TO Sylvester1;
GO
