php - 订单日期查询，语法错误

Question

我想使用以下查询来订购商店下订单的日期。我想按升序执行它们，但是当我尝试测试运行时出现以下错误:

[Syntax Error] line 0, col 7: Error: Expected IdentificationVariable | ScalarExpression | AggregateExpression | FunctionDeclaration | PartialObjectExpression | "(" Subselect ")" | CaseExpression, got 'order'

$orderSales = $this->getDoctrine()->getRepository("AppBundle:Order")->createQueryBuilder('order');

    $orderSales->orderBy('order.date', 'asc');
    $orderSales = $orderSales->getQuery();
    $orderResult = $orderSales->getResult();

我在 .twig 模板中渲染 orderResult

return $this->render('admin/store/sales/adminsales.html.twig', array(
                            'orderResult' =>$orderResult
    ));

Answer 1

您应该在您的存储库中声明您的 QueryBuilder，例如 (createQueryBuilder 接受参数):

public function findOrdersByDate()
{
    $qb = $this->createQueryBuilder('o')
        ->orderBy('o.date', 'asc');

    return $qb
        ->getQuery()
        ->getResult();
}

在你的 Controller 中:

$orderResult = $this->getDoctrine()->getRepository("AppBundle:Order")->findOrdersByDate();

编辑:正如 Imanali Mamadiev 所指出的:将“order”替换为“o”以避免 SQL 关键字冲突
