+## Examples  
+  
+### A. Grant and revoke
+ **APPLIES TO:**  [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)], [!INCLUDE[ssSDS](../../includes/sssds-md.md)]  
+  
+The following example creates a schema, a contained database user, and a new role on a user database. It adds the user to the role, grants SELECT permission on the schema to the role, and then removes (`REVOKE`) that permission to the role.
+
+  
+```sql  
+CREATE SCHEMA Sales;  
+GO
+CREATE USER Joe without login;
+GO
+CREATE ROLE Vendors;
+GO
+ALTER ROLE Vendors ADD MEMBER Joe; 
+GO
+GRANT SELECT ON SCHEMA :: Sales TO Vendors;
+GO
+REVOKE SELECT ON SCHEMA :: Sales TO Vendors;
+GO
+ 
+```
