is there a better way to upsert record with gorm?

i need add up values based on column its value if key has exist already.

the code below works as well. but it looks dumb if there's a lot of columns to upsert.

is there a elegant way to do same thing with gorm?

thanks for any help. ^_^

CREATE TABLE `daily_report` (
  `id` INT UNSIGNED NOT NULL AUTO_INCREMENT,
  `day` INT UNSIGNED NOT NULL,
  `orders` INT UNSIGNED NOT NULL DEFAULT 0,
  `money` DECIMAL(17,4) NOT NULL DEFAULT 0,
  `effective_amount` DECIMAL(17,4) NOT NULL DEFAULT 0,
  PRIMARY KEY (`id`) USING BTREE,
  UNIQUE `idx_day` (`day`) USING BTREE
) ENGINE=INNODB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8mb4; 


type DailyReport struct {
    Day             int64
    Orders          int
    Money           float64
    EffectiveAmount float64
}

func (d *DailyReport) Create(r []*DailyReport, db *gorm.DB) error {
    return db.Clauses(
        clause.OnConflict{
            DoUpdates: clause.Assignments(map[string]interface{}{
                "orders":           gorm.Expr("`orders` + VALUES(`orders`)"),
                "money":            gorm.Expr("`money` + VALUES(`money`)"),
                "effective_amount": gorm.Expr("`effective_amount` + VALUES(`effective_amount`)"),
            }),
        }).Create(&r).Error
}

var rows []*DailyReport
rows = append(rows, &DailyReport{
    Day:             1001,
    Orders:          10,
    Money:           2000,
    EffectiveAmount: 1000,
})
var r *DailyReport
_ = r.Create(rows, db)
