在MySQL 5.7中，刪除了mysql.user表字段中的password字段，現在該字段名稱為'authentication_string'。

首先選擇數據庫：

mysql>use mysql;

然后顯示表格：

mysql>show tables;

您將找到用戶表，現在讓我們看一下它的字段：

mysql> describe user;

+------------------------+-----------------------------------+------+-----+-----------------------+-------+

45 rows in set (0.00 sec)

驚喜！沒有名為“ password”的字段，而密碼為“ authentication_string”。因此，只需執行以下操作：

update user set authentication_string=password('1111') where user='root';

現在，一切都會好的。

與MySQL 5.6相比，變化非常廣泛：MySQL 5.7的新增功能
