参考:
先设置grant_skip_tables
1. use mysql
2. update user set authentication_string='' where user='root' 如果这个字段有值,先置为空
3. flush privileges 刷新权限表
4.ALTER user 'root'@'localhost' IDENTIFIED BY 'Tianya1234' 修改root 密码

1、首先,选中一个数据库world,为了防止破坏其他的数据库表,这里新建一张数据库表t_people_info,如下图所示。
2、创建t_people_info数据库表,可以查看下表结构,使用SQL语句或直接点击进行查看表结构。
3、接着,在world数据库找到”事件“菜单项,鼠标右键”创建事件...“,如下图所示,输入事件名称,单击”创建“。
4、就会生成insert_data事件,如下图所示。
5、接着,编写insert_data事件,每10秒钟向t_people_info插入一条数据。
6、最后查看事件的状态,调用事件运行成功。
