如何将原始 SQL 查询的结果传递到 Symfony2 中查看

Question

我有这段代码在我的控制器中使用原始 SQL 查询：

        $sql1 = "SELECT completion_date FROM enviro_figures_upload GROUP BY YEAR(completion_date), MONTH(completion_date) DESC;";

        $activeDate = $this->getDoctrine()->getManager()->getConnection()->prepare($sql1);
        $activeDate->execute();
        $activeDate->fetchAll();

此代码然后将数据传递到视图，然后在下拉日期选择器中使用该视图。但是，即使在数据库上运行 SQL 查询 returns 我需要的结果，也没有结果传递给视图。为了将此数据传递给视图，我缺少什么？

Answer 1

$activeDate->execute(); $activeDate->fetchAll(); This code then passes the data to the view ...

此代码不会将数据传递给查看，您必须在 render 方法中通过数组选项传递数据才能查看..

像这样：

$sql1 = "SELECT completion_date FROM enviro_figures_upload GROUP BY YEAR(completion_date), MONTH(completion_date) DESC;";

$activeDate = $this->getDoctrine()->getManager()->getConnection()->prepare($sql1);
$activeDate->execute();

$result = $activeDate->fetchAll();

return $this->render('TEMPLATE_PATH', [
    'result' => $result
]);
