Question

我有一个查询，它返回我用于下拉日期选择器的日期列表，这是SQL查询。

SELECT `completion_date`
FROM `enviro_figures_upload`
GROUP BY YEAR( completion_date ) , MONTH( completion_date ) 
ORDER BY YEAR( completion_date ) ASC , MONTH( completion_date ) ASC

通过phpMyAdmin，查询以我需要的顺序返回我需要的结果：

在我的Symfony2应用程序中，这是我用来将这些数据提供给我的应用程序的代码：

    $sql4 = "SELECT `completion_date` FROM `enviro_figures_upload` GROUP BY YEAR(completion_date), MONTH(completion_date) ORDER BY YEAR(completion_date) ASC, MONTH(completion_date) ASC;";

    $activeDateSelect = $this->getDoctrine()->getManager()->getConnection()->prepare($sql4);
    $activeDateSelect->execute();

    $activeDate = $activeDateSelect->fetchAll();

但是，结果并没有按照正确的顺序排列。返回的结果如下：

我无法理解为什么结果会像这样改变。我该怎么办？

修改日期为VARCHAR而非DATE的字段类型。这是因为构建此功能的客户端无法更改Excel中用于创建CSV的日期格式。因此，日期以英国格式上传，然后我将日期重新格式化为当前格式。

这是fetchAll()：

的var_dump

编辑2
我通过Twig迭代结果：

{% for ad in actdate %}
     <option value="{{ad.completion_date|date('Y-m')}}">{{ad.completion_date|date('F Y')}}</option>
{% endfor %}

ORDER BY不使用Symfony2中的原始SQL查询，但适用于MySQL数据库
