Laravel Eloquent "WHERE NOT IN"

Question

Query Builder:

DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();

Eloquent:

SomeModel::select(..)->whereNotIn('book_price', [100,200])->get();

You can use WhereNotIn in following way also:

ModelName::whereNotIn('book_price', [100,200])->get(['field_name1','field_name2']);

This will return collection of Record with specific fields

I had problems making a sub query until I added the method ->toArray() to the result, I hope it helps more than one since I had a good time looking for the solution.

Example

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

Query Builder:

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

Eloquent:

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

The dynamic way of implement whereNotIn:

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

You can use this example for dynamically calling the Where NOT IN

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

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