Question

我正在尝试从后端获取信息到vuejs multiselect组件。但是我很难将原始sql转换为laravel。

这是我需要转换的原始代码：

select name, users.id
from users, ( select if(user_id = $bruker, friend_id, user_id ) as venn, friends.*
from friends
where user_id = $bruker or friend_id = $bruker) as venner
where users.id = venner.venn;

我尝试了此代码，但是在组件中显示为“列表为空”。当我更改whereRaw时，我可以获得一些信息，但没有正确的信息。

$users = \DB::table('users', 
DB::raw(
"select if(user_id = $bruker, friend_id, user_id ) as venn, 
 friends.*
 from friends
 where user_id = $bruker or friend_id = $bruker) as venner
"))
->whereRaw("users.id = venner.venn")
->pluck('name');

对不起，英语不好。

我解决了我的问题。我需要做的就是使数组从查询到集合。这样我冷使用原始SQL。 maby不是最好的解决方案，但它确实有效。

代码如下：

 $bruker = \Auth::user()->id;
    $coll = \DB::select
        ("SELECT name
        from users, ( select if(user_id = $bruker, friend_id, user_id ) as venn, friends.*
        from friends
        where user_id = $bruker or friend_id = $bruker) as venner
        where users.id = venner.venn
        and accepted = 1
        ");

        $users = collect($coll)->pluck('name');

    return $users;
