Mysql 无法保存最近的表！phpMyAdmin#1062-重复条目'；根'；对于键'；初级'；

所以我在workbench中制作了一个EER图：

然后我使用forward engineer创建数据库（还尝试了脚本复制方法）

这一切似乎都很好，但当我试图查看任何表时，我总是在phpMyAdmin中遇到这个错误：

我尝试导出数据库并导入，但没有改变任何东西

数据库备份：

任何帮助都将不胜感激

因此我重新启动了计算机，重新启动了以管理员身份运行的xampp，安装了服务并再次检查了phpMyAdmin，现在错误消失了

奇怪的是，这个错误只显示在使用mysql workbench脚本创建的数据库中，而不是其他数据库中。

为什么物理表中没有主键？有主键，但它在代码末尾添加了主键，这很奇怪。更改表

tblstaff\u br\u tblevents

添加主键（

tblstaff\u StaffID

，

tblevents\u EventID

），添加键

fk\u br\u EventID\u idx

（

tblevents\u EventID

），添加键

fk\u br\u StaffID\u idx

（

tblstaffid

）；
