查询中的ORDER BY与复合字段

Question

我有下一个mysql表结构：

++++++++++++++++++++++++++++++++++++
+ id + value + month + year + type +
++++++++++++++++++++++++++++++++++++

我想做下一个选择：

SELECT 
 * 
FROM 
 Table

但是ORDER BY选项。我想在YEAR-MONTH复合字段DESC上对结果进行排序。

我需要这样的东西：

SELECT 
 * 
FROM 
 Table
ORDER BY 
 YEAR-MONTH
DESC

我怎么能这样做？

Answer 1

SELECT 
    * 
FROM 
    Table
ORDER BY 
    YEAR DESC, 
    MONTH DESC

Answer 2

SELECT CONCAT( year, month ) AS _sorter, *
FROM table
ORDER BY _sorter
