Laravel - 比日期语法更少/更大的地方

This is not showing the correct count. What is the correct syntax ?

$this->data['Tasks'] = \DB::table('tb_tasks')->where('Status', 'like', 'Open%')->whereDate('DeadLine', '>', 'CURDATE()')->count();

Use a Carbon instance:

$this->data['Tasks'] = \DB::table('tb_tasks')->where('Status', 'like', 'Open%')->whereDate('DeadLine', '>', Carbon::now())->count();

Use DB::raw:

->where('datefield', '>', \DB::raw('NOW()'))
