// whereRaw$orders = DB::table('orders')    ->whereRaw('price > IF(state = "TX", ?, 100)', [200])    ->get();// havingRawProduct::groupBy('category_id')->havingRaw('COUNT(*) > 1')->get();// orderByRawUser::where('created_at', '>', '2016-01-01')  ->orderByRaw('(updated_at - created_at) desc')  ->get();

// Instead of$users = User::all();foreach ($users as $user) { }// You can doUser::chunk(100, function ($users) {    foreach ($users as $user) {        // ...    }});

$result = $products->whereNull('category_id')->update(['category_id' => 2]);

// you can pass an array of parameters to orWhere() Usual way$q->where('a', 1);$q->orWhere('b', 2);$q->orWhere('c', 3);$q->where('a', 1);$q->orWhere(['b' => 2, 'c' => 3]);
