如何修复更新密码时遇到的1064（4200）错误？

Question

我正在尝试重新安装MySQL 5.7.12。当我尝试使用

更新root用户的密码时

Dim xl As Excel.Application
For Each xl In Applications
If xl.Visible = False Then xl.Quit
Next

我收到此错误 -

mysql> use mysql;
Database changed 
mysql> update mysql.user set password = password<'mynewpass'> where user = 'root';
