DECLARE @cookie varbinary(8000);
EXEC sp_setapprole 'Sales11', 'fdsd896#gfdbfdkjgh700mM'
    , @fCreateCookie = true, @cookie = @cookie OUTPUT;
-- The application role is now active.
SELECT USER_NAME();

EXEC sp_unsetapprole @cookie;
-- The application role is no longer active.
-- The original context has now been restored.
