Laravel 查詢數據按照時間分組

首先取消嚴格模式：

// config/database.php
// 'strict' => true, // 嚴謹模式注釋掉

查詢構造器代碼：

//查詢構造器部分代碼
})->with(['device_field', 'device_field.device_field_log' => function($query) use($request){
            // 時間
            $time = floatval($request->input('time'));
            if($time > 8760){
                $time = 8760;
            }else if($time < 0.5){
                $time = 0.5;
            }
            // 查詢時間區間 
            // $query->whereBetween('created_at',[date("Y-m-d H:i:s", time() - ($time * 3600)),date("Y-m-d H:i:s", time())])->selectRaw("DATE_FORMAT(created_at, '%Y-%m-%d %H:%i') as date, id,device_id,device_field_id,name,created_at")->groupBy('date')->orderBy('date', 'desc');
            $query->whereBetween('created_at',[date("Y-m-d H:i:s", time() - ($time * 3600)),date("Y-m-d H:i:s", time())]);
            $query->select("*"); // 設置要查詢的字段(如果設置必須包含關聯的字段，否則數據查詢不到，如本例(device_id,device_field_id) 如：$query->select("device_id,device_field_id")
            $query->selectRaw("DATE_FORMAT(created_at, '%Y-%m-%d %H:%i') as date, id,device_id,device_field_id,name,created_at");
            $query->groupBy('date');
            $query->orderBy('date', 'desc');
        }])->get();
