Question

我正在使用Hibernate在mySql数据库中创建表。我有两张桌子＆＃34; conge＆＃34;和＆＃34;员工＆＃34;我有很多关系。＆＃34; conge＆＃34; table有一个雇员id的外键。

我注意到在我的表格中插入了两行＆＃34; conge＆＃34;我遇到了外键问题。我已经使用了hibernate和phpmyadmin来插入，插入两行后我总是遇到同样的问题。

这是我的错误

无法添加或更新子行：外键约束失败（concretepage。Conge，CONSTRAINT FKk1p9i6bbic92cgaad05k4smsg FOREIGN KEY（id）参考EMPLOYE （id））

谢谢，

更新我已导出数据库，这是sql文件

Answer 1

因为外键位于列ID而不是employee_id ...看：FOREIGN KEY（id）REFERENCES EMPLOYE（id））...并且您在Employee表中只有两行< / p>

带有hibernate的外键和mysql
