MySQL Root Password Reset on Windows: Why Do I Get a \'TIMESTAMP with implicit DEFAULT value is deprecated\' Warning?

Resetting MySQL Root Password on Windows: Troubleshooting Warnings

While resetting the root password for MySQL 5.6 on Windows, you may encounter the following warning:

2014-02-08 15:44:10 0 [Warning] TIMESTAMP with implicit DEFAULT value
is deprecated. Please use --explicit_defaults_for_timestamp server
option (see documentation for more details).

What Does the Warning Mean?

This warning pertains to a deprecated feature where TIMESTAMP columns were created with implicit DEFAULT values. While it doesn't necessarily indicate an error, it highlights a recommended best practice for specifying explicit defaults.

Should You Fix It?

Since the warning is not an error, it's not mandatory to fix it. You can choose to ignore it and proceed with the password reset process.

Command Window Behavior

If the command window is unresponsive after displaying the warning, you should not force-close it. The process is still running and will complete its operations. Wait for it to finish and display a message indicating completion.

Troubleshooting After Warning

Once the process completes, you may experience difficulties restarting the MySQL service. In this case, restart your Windows machine, and the service should start automatically. If you successfully use workbench functions with the new password, you can confirm that the reset was successful, and the warning was indeed just a warning.

Tips for Skipping Grant Tables

If you encounter further issues during the password reset process, you can try the following steps to skip grant tables:

1. Stop the MySQL service.
2. Go to the MySQL configuration directory.
3. Open the configuration file (e.g., my.ini).
4. Add the following line: skip-grant-tables
5. Save the changes.
6. Start the MySQL service.
7. Execute commands to update the root password.
8. Stop the MySQL service again.
9. Remove the skip-grant-tables line.
10. Start the MySQL service normally.
