查询构建器:

    DB::table('book_mast')
->select('book_name','dt_of_pub','pub_lang','no_page','book_price')
    ->whereNotIn('book_price', [100,200])->get();

口才:

BookMast::select('book_name','dt_of_pub','pub_lang','no_page','book_price')
->whereNotIn('book_price', [100,200])->get();

您可以使用此示例动态调用Where NOT IN

$user = User::where('company_id', '=', 1)->select('id)->get()->toArray();

$otherCompany = User::whereNotIn('id', $user)->get();

实现whereNotIn的动态方式:

 $users = User::where('status',0)->get();
    foreach ($users as $user) {
                $data[] = $user->id;
            }
    $available = User::orderBy('name', 'DEC')->whereNotIn('id', $data)->get();

或者试着在laravel里拔一下 在这里

DB::table('user')                 
          ->select('id','name')
          ->whereNotIn('id', DB::table('curses')->where('id_user', '=', $id)->pluck('user_id'))
          ->get();  

这是Laravel 7的工作变体

DB::table('user')                 
  ->select('id','name')
  ->whereNotIn('id', DB::table('curses')->where('id_user', $id)->pluck('id_user')->toArray())
  ->get();

可以通过以下方式使用WhereNotIn:

$category=DB::table('category')
          ->whereNotIn('category_id',[14 ,15])
          ->get();`enter code here`
