Scan结果映射错误

[zzuts]

执行 insert on duplicate key update price = price + 0 之后，再执行Scan()方法，结果映射错误。会直接扫描数据库全部记录

CREATE TABLE `products` (
  `id` bigint NOT NULL AUTO_INCREMENT,
  `created_at` datetime(3) DEFAULT NULL,
  `updated_at` datetime(3) DEFAULT NULL,
  `deleted_at` datetime(3) DEFAULT NULL,
  `code` varchar(255) DEFAULT NULL,
  `price` bigint DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `idx_code` (`code`)
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci

先创建两条记录

db.Create(&Product{Code: "D41", Price: 100})
db.Create(&Product{Code: "D42", Price: 100})

执行insert on duplicate key update语句

dst := &Product{
		Code:  "D42",
		Price: 0,
	}
tx := db.Begin()
	tx = tx.Table(dst.Name()).Clauses(clause.OnConflict{Columns: []clause.Column{{Name: "code"}}, DoUpdates: clause.Assignments(map[string]interface{}{"price": gorm.Expr("price + ?", dst.Price)})}).Create(dst)
	p := make([]Product, 0, 10)
	tx.Scan(&p)
fmt.Printf("tx scan ||%+v\n", p)
	tx.Commit()

如果on duplicate key update 执行的是 price = price+ 0 这样无改动的语句时，后面再执行Scan。会把sql中所有记录扫出来，Debug()一下，发现执行的是SELECT * FROMproductsWHEREproducts.deleted_at IS NULL
