Symfony

Question

所以我使用制造商包提供的 make:entity 命令在 Symfony 中创建了 4 个实体。然后我使用 make:migration 命令获取 Symfony 生成的迁移文件但是当我尝试运行命令 doctrine:migrations:migrate 它输出这个错误：

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 'groups (id INT AUTO_INCREMENT NOT NULL, ort_id INT NOT NULL, confession VARCHAR(' at line 1

我不知道为什么它会输出错误，因为这个文件是由 Symfony 使用 make:migration 命令自动生成的，但这是它生成的迁移文件

groups 是 MySQL 中的保留关键字，有关此类关键字的完整列表，请参阅 https://dev.mysql.com/doc/refman/8.0/en/keywords.html。

您应该引用 table 名称（带反引号），或者在您的实体中使用另一个 table 名称（这是更好的解决方案，因为这样可以避免在未来）
