执行时出现异常'SELECT count(DISTINCT o0_.id) AS sclr_0 FROM Order o0_'

Question

在 Symfony 3.4.8 上使用 SonataAdminBundle 时遇到以下问题：

当我查看我的 table 的列表时，出现以下错误。

An exception occurred while executing 'SELECT count(DISTINCT o0_.id) AS sclr_0 FROM Order o0_':

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 'Order o0_' at line 1

请帮帮我...

Answer 1

Doctrine 将您的 table 名称按原样添加到查询中，没有反引号。因此，mysql 判定这是语法错误，因为 ORDER BY 是不区分大小写的保留关键字 sql。

要解决此问题，您可以在映射中重命名 table，例如

@ORM\Table(name="Order_postfix")

您还可以通过在映射 they say 中使用反引号手动转义 table 名称。像这样：

@ORM\Table(name="`Order`")
