如何在 laravel 5.2 中向表“用户”插入值？

Question

我想在“用户”表中插入员工详细信息用户名、区域。

我有 CreateEmployeeController 和以下代码

createemployee.blade.php 查看文件。

当我点击菜单 Create Employee is 时会显示以下错误

Connection.php 第 662 行中的 QueryException： SQLSTATE[42000]：语法错误或访问冲突：1066 表/别名：'users' 非唯一（SQL：select * from users inner join users on users.id = users.@987654326 @ 其中users.deleted_at 为空）

控制器文件：

我无法全面了解您的问题，但据我所知，您在 join 语句中使用相同的表/列名称，您可以这样做：

$employee = CreateEmployee::join('users', 'create_employees.id','=', 'users.employee_id')->get();

希望这会有所帮助！
