为什么当我尝试创建数据库时出现错误 3734

Question

我创建了一个图表并尝试使用正向工程，但收到错误 3734：无法添加外键约束。引用表“user”中缺少约束“fk_order_review_user1”的列“user_id”。

我删除了 2 个选项卡（“order_review”和“favorites”）并成功完成了前向工程师。我该如何解决这个问题？我是 MySQL 的初学者，所以我不明白如何调试这个问题

在 MySQL 标题“user”中 - MySQL 内的默认标题，所以我收到错误 3734。我更改了他，但如果需要，请尝试向表发出此请求：

我的项目.user
MyDB.user

（对不起我的英语）
