mysql - SQL 查询在 Web 托管上执行时出现错误，但在 localhost 上运行时没有问题

Question

我想在线上传我的项目。最近我购买了网络托管服务，并且我已经检查了我和他们的服务器的版本 - 10.1.38-MariaDB。以下查询在我的本地主机数据库服务器上运行没有问题，但是当我尝试在线运行它时，出现以下错误，为什么？

1005 - 无法创建表psyclade_project。companies(errno:150“外键约束格式不正确”)

显然问题是外键，我该如何解决它？

查询是:

如果您想使用 phpMyAdmin 中的 SQL 选项卡执行此转储，则必须取消选中“启用外键检查”框，您可以在“Go”按钮附近找到该框。
