Php MySQL上具有特殊字符列的Doctrine findBy（）

我有一个MySQL表，其简短描述如下

+-----------------------------------+---------------+------+-----+---------+----------------+
| Field                             | Type          | Null | Key | Default | Extra          |
+-----------------------------------+---------------+------+-----+---------+----------------+
| id                                | bigint(20)    | NO   | PRI | NULL    | auto_increment |
| trailer_number                    | varchar(20)   | YES  | MUL | NULL    |                |
| discount_structure (%)            | decimal(10,2) | NO   |     | NULL    |                |
| net_purchase_price                | decimal(10,2) | NO   |     | NULL    |                |
| capitalised_extras                | decimal(10,2) | NO   |     | NULL    |                |
| maximum_write-off_period (Months) | int(11)       | NO   |     | NULL    |                |
| maximum_write-off_period (KMS)    | int(11)       | NO   |     | NULL    |                |
| residual_value (%)                | decimal(10,2) | NO   |     | NULL    |                |
| interest_rate (%)                 | decimal(10,2) | NO   |     | NULL    |                |
| insurance (%)                     | decimal(10,2) | NO   |     | NULL    |                |
| coastal_wholesale_price_of_fuel   | decimal(10,2) | NO   |     | NULL    |                |
+-----------------------------------+---------------+------+-----+---------+----------------+

为了处理列名中的

（%）

等，我必须在SQL调用中使用反勾号

SELECT 
    t0.trailer_number AS trailer_number_1, 
    t0.`discount_structure (%)` AS discount_structure_68, 
    t0.net_purchase_price AS net_purchase_price_69, 
    t0.capitalised_extras AS capitalised_extras_70, 
    t0.`maximum_write-off_period (Months)` AS maximum_writeoff_periodMonths_71, 
    t0.`maximum_write-off_period (KMS)` AS maximum_writeoff_periodKMS_72, 
    t0.`residual_value (%)` AS residual_value_73, 
    t0.`interest_rate (%)` AS interest_rate_74, 
    t0.`insurance (%)` AS insurance_75, 
    t0.coastal_wholesale_price_of_fuel AS coastal_wholesale_price_of_fuel_76, 
    t0.id AS id_77 
FROM fox.trailer t0 WHERE t0.deleted = 0

在我的实体中，我已将反勾号添加到我的列名中，例如

/**
 * @var string
 * @ORM\Column(name="`discount_structure (%)`", type="decimal", precision=10, scale=2, nullable=false)
 */
private $discountStructure;

我打电话的时候

$trailes=$this->em->getRepository（'FoxBundle:Trailer'）->findBydeleted（0）

我得到以下错误

[Doctrine\DBAL\Exception\SyntaxErrorException]

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%) AS discount_structure_68, t0.net_purchase_price AS net_purchase_price_69, t0.' at line 1

我没有数据库，因此无法更改列名。
我还可以做些什么来让findBy（）函数工作吗？
在实体列名中添加反勾号确实有效

/**
 * @var string
 * @ORM\Column(name="`discount_structure (%)`", type="decimal", precision=10, scale=2, nullable=false)
 */
private $discountStructure;

您必须记住清除缓存

php bin/console cache:clear 
php bin/console cache:clear --env=prod 
php bin/console doctrine:cache:clear-metadata 
php bin/console doctrine:cache:clear-query 
php bin/console doctrine:cache:clear-result

这不是一个答案，因为你知道如何解决你的错误，但在某种程度上避免了这些事情，如果你只是使用简单的名字（这是无论如何建议），你不会有任何问题。只需保持平面a-z/u，没有花哨的符号。如果你真的想，你甚至可以在简单的名称后面加上“百分比”之类的后缀。@JennevanderMeer我也会将只使用的字母数字字符减半，但我没有创建数据库，只有对它的读取权限，所以我不能更改列名。我只做了一个小测试
name=“`name（%）`
，还有一个findAll，效果很好，所以我不认为这是问题所在，repo函数findbydeletted做什么？@JennevanderMeer刚刚测试findAll（）对我也有效。findByColumnName（“参数”）允许您按特定条件进行筛选。在我的例子中，我希望记录没有被标记为已删除（即deleted=false）。我不确定它在后台是如何做到的。我无法重现这一点，即使在我的测试实体中添加一个已删除的属性并执行findByDeleted也能正常工作。恐怕您必须在stacktrace/symfony调试工具栏中做一些真正深入的挖掘，它可能会告诉您更多信息（如果单击图标，您可以看到查询详细信息）。您还可以尝试一件小事（我认为这不会在内部改变任何东西），那就是尝试
…->findBy（['deleted'=>0]）并且可能更新？我的测试实例来自大约两周前。但我从来没有真正深入到这么深，所以除了这个，我也没有想法
