$this->node = \DB::table('permission')
                ->select('permission.id','object.name as object_name','permission.created_at','object.id as object_id')
                ->join('object','object.id','=','permission.object_id')
                ->join('action','action.id','permission.action_id')
                ->where('permission.person_id',$this->person['id'])
                ->groupBy('permission.object_id')
                ->orderBy('permission.created_at','desc')
                ->paginate(5);

Laravel Framework报告错误：

QueryException in Connection.PHP line 761: sqlSTATE[42000]: Syntax
error or access violation: 1055 ‘permission.id’ isn’t in GROUP
BY (sql: select permission.id,object.name as object_name,
permission.created_at,object.id as object_id from
permission inner join object on object.id =
permission.object_id inner join action on action.id =
permission.action_id where permission.person_id = 1 group by
permission.object_id order by permission.created_at desc limit
5 offset 0)

我在AppServiceProvider中添加了一个Eloquent调试函数DB :: listen：

use Illuminate\Support\Facades\DB;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //
         DB::listen(function ($query) {

            echo "<pre>";
            print_r($query->sql);
            echo "</pre>";

            // $query->sql
            // $query->bindings
            // $query->time
        });
    }
    ...

它确实打印了这个SQL查询：

select  `permission`.`id`,`object`.`name` as `object_name`,`permission`.`created_at`,`object`.`id` as `object_id` 
from `permission` 
inner join `object` on `object`.`id` = `permission`.`object_id` 
inner join `action` on `action`.`id` = `permission`.`action_id` 
where `permission`.`person_id` = 1 
group by `permission`.`object_id` 
order by `permission`.`created_at` desc 
limit 5 offset 0

这在MysqL中通过PHPMyAdmin有效,这里是查询的输出：

即便如此,我直接在MysqL命令中测试它确实工作得很好,看看MysqL输出：

任何的想法？

谢谢
