说我必须遵循:

Select OrderID = 
    Case OrderID 
        When 1 Then 'Customer1'
        When 2 Then 'Customer2'
        When 3 Then 'Customer2'
        Else 'Unknown Customer'
    End 
From OrdersPlaced

是否可以添加或执行以下操作:

Select OrderID = 
    Case OrderID 
        When 1 Then 'Customer1'
        When 2 Or 3 Then 'Customer2'
        Else 'Unknown Customer'
    End 
From OrdersPlaced
