嗨，我有一个3连接表，它自然会有重复的列名，例如id。简而言之，我有3个表，分别是：
bas_role
id
name
bas_app
id
app_name
bas_role_app
id
role_id
app_id

这里是问题，我想加载bas_role_app的列ID，因此可以更轻松地完成任务。但是当我执行dd（$ app）;时，它总是返回结果，例如：
+"id": 4
+"app_name": "app"
+"app_type": null
+"description": "display app"
+"menu_name": "app"
+"menu_url": "/app"
+"menu_parent_id": null
+"role_id": 4
+"app_id": 7
+"priv_access": "N"
+"priv_insert": "N"
+"priv_delete": "N"
+"priv_update": "N"
+"priv_export": "N"
+"priv_print": "N"
+"name": "siswa"
+"remark": "study"
据此，我知道查询为进程加载了错误的ID，因为在bas_role_app中，它已达到约1100 id（虚拟数据正在发生...。）
所以我的问题是，如何加载bas_role_app的ID，以便可以在view foreach循环中使用它（而不是bas_role和bas_app的ID），并且也可以执行crud？
答案 0 :(得分：0)
尝试为您要选择的id列选择一个列别名，如下所示：
$app = DB::table('bas_role_app')
->join('bas_role_app','bas_app.id','=','bas_role_app.app_id')
->join('bas_role','bas_role_app.role_id','=','bas_role.id')
->from('bas_app')
->select('bas_app.*,bas_role_app.id as bas_role_app_id')
答案 1 :(得分：0)
没关系，显然，我必须使用display和getroleapp方法添加相同的查询，我应该更加小心
