所以我试图从mysql中导出一个架构/数据库，我收到了一个奇怪的错误。
我还运行了几个授权命令（见下文），我认为这些命令应该足以让我导出数据。在MySQLWorkbench上，我以grand命令中提到的用户身份登录。
任何想法我可能做错了什么？非常感谢
错误：
Unhandled exception: Error querying security information: Error executing 'SELECT * FROM mysql.user WHERE User='mydb' AND Host='myhost.com' ORDER BY User, Host'
SELECT command denied to user 'mydb'@'my-ip-here' for table 'user'.
SQL Error: 1142
授予命令：
mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
