ERROR 1449 (HY000): The user specified as a definer ('mysql.infoschema'@'localhost') does not exist

这个错误是由于MySQL数据库中的用户定义者（definer）不存在导致的。用户定义者指的是在创建或修改存储过程、触发器等对象时指定的用户。根据引用和引用，解决这个错误的方法是创建一个名为'mysql.infoschema'的用户，并授予对所有数据库的所有权限。具体的操作步骤如下：
1. 在MySQL中执行以下命令创建用户：
CREATE USER 'mysql.infoschema'@'localhost' IDENTIFIED BY '123456';
2. 授予该用户对所有数据库的所有权限：
GRANT ALL PRIVILEGES ON *.* TO 'mysql.infoschema'@'localhost';
3. 刷新权限以使更改生效：
FLUSH PRIVILEGES;
如果你在远程连接数据库时遇到"plugin caching_sha2_password could not be loaded"错误，你可以尝试通过修改密码加密插件来解决。执行以下命令：
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

这样，你就创建了一个名为'mysql.infoschema'的用户，并为该用户授予了必要的权限，同时也解决了相关的报错信息。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
