In MySQL, you need to use the FLUSH PRIVILEGES command after making changes to the user privileges directly in the grant tables (such as mysql.user, mysql.db, etc.) through INSERT, UPDATE, or DELETE statements. This command reloads the privilege tables in memory, ensuring that the changes take effect immediately. However, if you use the GRANT, REVOKE, or SET PASSWORD commands, a manual flush is not necessary, as these commands automatically update the privileges.

What does an anonymous account mean in MySQL?

In MySQL, an anonymous account refers to a user account that does not have a specified username. It is created when a user connects to the database without providing a username, allowing access based on the privileges associated with the anonymous user. This can be useful for granting limited access to users who do not need to authenticate with specific credentials. However, relying on anonymous accounts can pose security risks, and it's generally recommended to use explicit user accounts with defined privileges.
