我有一张这样的桌子：

Date   | Expedition Name | Invoice
___________________________________________
4/6/12 | Starsindo       | X001908
4/6/12 | Starsindo       | X001900
4/6/12 | De Ros indah    | X002008
4/6/12 | De Ros indah    | X002108
4/6/12 | De Ros indah    | X002208
4/6/12 | Starsindo       | X002308
4/6/12 | Starsindo       | X002408
4/6/12 | Starsindo       | X002508 
4/6/12 | Japex           | X002608

我刚刚创建了这个查询，但仍然感到困惑：

Select  * From tb_exp_expor  Order By nama_exp_expor DESC
