Laravel using Sum and Groupby

I would like to fetch sum of quantity in each month, so that I can display on bar chart quantities against month

This is what I thought but didn't workout

 $data1 = Borrow::groupBy(function($d) {
 return Carbon::parse($d->created_at)->format('m')->sum('quantity');
 })->get();

My table structure

Schema::create('borrows', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('member_id');
        $table->integer('book_id');
        $table->integer('quantity');
        $table->integer('status')->default(0);
        $table->timestamps();
    });

that a collection group by not an eloquent groupby

if you want to do it with eloquent, gotta:

 $data1 = Borrow::selectRaw('SUM(quantity) as qt, MONTH(created_at) as borrowMonth')
      ->groupBy('borrowMonth')->get();

if you want to do it with the collection groupBy method, you should first do the get, then the groupBy.

As in, though im not sure what you're trying to accomplish with what you do inside the callback..

 $data1 = Borrow::get()->groupBy(function($d) {
 return Carbon::parse($d->created_at)->format('m')->sum('quantity');
 });

try this query , you will get month wise count :

use DB;


 $month_wise_count=DB::table("borrows")
        ->select(DB::raw('CONCAT(MONTHNAME(created_at), "-",  YEAR(created_at)) AS month_year'),
                DB::raw("MONTH(created_at) as month , YEAR(created_at) as year"),
                DB::raw("(COUNT(*)) as total_records"),
                DB::row("(SUM('quantity') as total_value"))
        ->orderBy(DB::raw("MONTH(created_at),YEAR(created_at)"))
        ->groupBy(DB::raw("MONTH(created_at),YEAR(created_at)"))
        ->get();
