` package main

"gorm.io/gorm/clause"
)
type TT struct {
ID int gorm:"not null;primaryKey;comment:id"

}
func main() { var dsn = "xx:xx@tcp(xx:xx)/test?autocommit=true&charset=utf8mb4,utf8&loc=Local&parseTime=true&writeTimeout=30s&readTimeout=60s&timeout=10s" dbConn, err := gorm.Open(mysql.Open(dsn), &gorm.Config{}) if err != nil { fmt.Println(err) return } if err := dbConn.AutoMigrate(&TT{}); err != nil { fmt.Println(err) return } var t = TT{ ID: 1, Name: "a", CreateTime: time.Now(), UpdateTime: time.Now(), } if err = dbConn.Clauses(clause.OnConflict{UpdateAll: true}).Create(&t).Error; err != nil { fmt.Println(err) return } t.UpdateTime = time.Now().Add(10 * time.Second) if err = dbConn.Clauses(clause.OnConflict{UpdateAll: true}).Create(&t).Error; err != nil { fmt.Println(err) return } var t2 TT if err = dbConn.First(&t2).Error; err != nil { fmt.Println(err) return } if t2.UpdateTime.Format("2006-01-02 15:04:05") != t.UpdateTime.Format("2006-01-02 15:04:05") { fmt.Printf("expect %s but %s", t.UpdateTime.Format("2006-01-02 15:04:05"), t2.UpdateTime.Format("2006-01-02 15:04:05")) } } `
数据库中的表结构
CREATE TABLEtts(idbigint(20) NOT NULL AUTO_INCREMENT COMMENT 'id',namevarchar(191) NOT NULL DEFAULT '' COMMENT '任务名',update_timedatetime(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3) COMMENT '更新时间',create_timedatetime(3) NOT NULL DEFAULT CURRENT_TIMESTAMP(3) COMMENT '创建时间',
PRIMARY KEY (id),
KEYidx_update_time(update_time)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4
结果：
update_time字段并没有被更新
