Question

我正在尝试使用doctrine / orm 2.5.1进行简单的->find()。

查询非常简单：

$this->get('order_repository')->find(10);

但这会产生一个复杂的查询：

SELECT s0_.number AS number_0，s0_.state AS state_1，s0_.completed_at AS completed_at_2，s0_.items_total AS items_total_3，s0_.adjustments_total AS adjustment_total_4，s0_.total AS total_5，s0_.created_at AS created_at_6，s0_.updated_at AS updated_at_7，s0_.deleted_at AS deleted_at_8，s0_.id AS id_9，s0_.expires_at AS expires_at_10，s1_.currency AS currency_11，s1_.checkout_state AS checkout_state_12，s1_.payment_state AS payment_state_13，s1_.shipping_state AS shipping_state_14，s2_.quantity AS quantity_15， s2_.unit_price AS unit_price_16，s2_.adjustments_total AS adjustment_total_17，s2_.total AS total_18，s2_.is_immutable AS is_immutable_19，s2_.id AS id_20，s1_.channel_id AS channel_id_21，s1_.shipping_address_id AS shipping_address_id_22，s1_.billing_address_id AS billing_address_id_23，s1_。 customer_id AS customer_id_24，s1_.offer_id AS offer_id_25，s2_.order_id AS order_id_26，s2_.variant_id AS variant_id_27 FROM sylius_order s1_ LEFT JOIN sylius_order_item s2_ ON s1_.id = s 2_.order_id WHERE（s1_.id = 10）AND（s1_.deleted_at IS NULL）'

出现以下错误：

SQLSTATE [42S22]：找不到列：1054'字段列表'中的未知列's0_.number'

我可以看到s0_没有在查询的任何地方定义。这些别名是从学说中自动生成的，我只是不明白为什么它使用s0_然后将其跳到FROM上的s1_，其中包含s0 _上提到的列。*

Answer 1

我在同一个问题上花了一个小时;你可能犯了和我一样的错误。

我遇到的问题是.yml模式定义。在我定义表格之间关系的部分中，我有这个目标实体：

targetEntity: mlEmailNotif

而不是

targetEntity: MlEmailNotif

所以小写＆＃39; m＆＃39; make doctrine为新表创建一个新别名（php比较区分大小写）。

Answer 2

问题出在这里：SELECT s0_.number as number_0 - 看来列号没有定义，或者映射（注释，yml，php）和架构（mysql）之间存在差异。

如果运行php app / console doctrine，那么是否有任何SQL命令：schema：update --dump-sql？如果是，则必须根据映射的实体更新架构。

使用错误的表别名
