即使我将设置“严格”设置为 false，laravel 5.5 group by 在单个列上也不起作用。我已经尝试了 mysql 工作台中的原始查询，它工作正常，但我在 laravel 上遇到此错误：

SQLSTATE[42000]: Syntax error or access violation: 1055 'hammer.vehicle.consignor_id' isn't in GROUP BY (SQL: select `vehicle`.*, `vehicle_brand`.`vehicle_brand_name`, `vehicle_model`.`vehicle_model_name`, `vehicle_variant`.`vehicle_variant_name`, `vehicle_model`.`year`, `vehicle`.`vehicle_id` from `vehicle` left join `vehicle_brand` on `vehicle_brand`.`vehicle_brand_id` = `vehicle`.`vehicle_brand_id` left join `vehicle_model` on `vehicle_model`.`vehicle_brand_id` = `vehicle_brand`.`vehicle_brand_id` left join `vehicle_variant` on `vehicle_variant`.`vehicle_model_id` = `vehicle_model`.`vehicle_model_id` group by `vehicle`.`vehicle_id` limit 10 offset 0)

这是导致错误的laravel代码

\DB::table('vehicle')
                    ->select('vehicle.*', 'vehicle_brand.vehicle_brand_name', 'vehicle_model.vehicle_model_name', 'vehicle_variant.vehicle_variant_name', 'vehicle_model.year', 'vehicle.vehicle_id')
                    ->leftJoin('vehicle_brand', 'vehicle_brand.vehicle_brand_id', '=', 'vehicle.vehicle_brand_id')
                    ->leftJoin('vehicle_model', 'vehicle_model.vehicle_brand_id', '=', 'vehicle_brand.vehicle_brand_id')
                    ->leftJoin('vehicle_variant', 'vehicle_variant.vehicle_model_id', '=', 'vehicle_model.vehicle_model_id')
                    ->where($where)
                    ->groupBy('vehicle.vehicle_id')
                    ->paginate(10);

配置“严格”中的 mysql 设置已设置为 false

我认为这是导致问题的严格模式，检查config/database.php并检查内部mysql，然后更改

'strict' => true,

至

'strict' => false,

因为正如在这个线程中提到的

如果设置为 true，那么它会在查询时添加 ONLY_FULL_GROUP_BY。

或者您可以尝试only_full_group_by通过执行以下操作来禁用该设置：

mysql> set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

正如这里建议的那样。
