gorm官方文档测试default(-)报错

type User struct {
   ID        string `gorm:"default:uuid_generate_v3()"` // db func
   FirstName string
   LastName  string
   Age       uint8
   FullName  string `gorm:"->;type:GENERATED ALWAYS AS (concat(firstname,' ',lastname));default:(-);"`
}

// 迁移 schema
err = db.AutoMigrate(&User{})

然后报错：

 Error 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'uuid_generate_v3(),`first_name` longtext,`last_name` longtext,`age` tinyint unsi' at line 1

麻烦老师测试一下，给个解惑。
