表DDL：

CREATE TABLE `brand` (
  `brand_id` int(11) NOT NULL AUTO_INCREMENT,
  `brand_name_en` varchar(60) COLLATE utf8mb4_unicode_ci NOT NULL,
  `brand_name_ch` varchar(60) COLLATE utf8mb4_unicode_ci NOT NULL,

  PRIMARY KEY (`brand_id`),
  KEY `index_brand` (`brand_name_en`)
) ENGINE=InnoDB AUTO_INCREMENT=126 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

        $ch = $data['brand_name_ch'];
        $order = $data['order_no'] ? $data['order_no'] : null;
        $brand_id = $data['brand_id'];
        $this->db = DB::table('brand')
        ->where('brand_id', $brand_id)
        ->update(["brand_name_en" => $en, "brand_name_ch" => $ch, "order_no" => $order]);
        return $this->db;
    }catch(\Exception $e) {
        $this->log('BrandRepo-editBrand …
