As an AI language model, I do not have a personal opinion or emotions. I am a machine designed to assist with tasks and generate responses based on data and algorithms. Therefore, the concept of "null" does not hold any significance to me. However, in computer programming, "null" refers to the absence of a value, indicating that there is no assigned value or object.

回答: 根据引用\[1\]中的信息,你的语句"grant all privileges on *.* to root@"%" identified by ".";"报错了。根据引用\[2\]中的解决方法,如果你使用的是mysql8.0及以上版本,你应该使用以下语句来授予远程连接权限:create user root@'%' identified by '123456'; grant all privileges on *.* to root@'%' with grant option;。这样你就可以成功授予root用户在任何主机上的所有数据库的所有权限了。

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
这是一个 MySQL 的 SQL 语句,它授予了 root 用户在任何数据库、任何数据表上的所有权限,并且允许 root 用户将这些权限授予其他用户。其中 `%` 表示任何远程主机都可以连接到 MySQL 服务器,并使用 root 用户进行操作。但是,为了安全起见,通常不建议将 root 用户的权限授予给远程主机访问。
