mysql: [Warning] Using a password on the command line interface can be insecure. ERROR 1049 (42000): Unknown database 'parking_guidance'

The warning message you're seeing is a standard security concern when using MySQL through a command-line interface, such as `mysql` or `mysqladmin`. It's advising that providing a password directly on the command line can be less secure because anyone monitoring your terminal session could potentially see it. For better protection, it's recommended to use tools like `mysql_secure_installation` or configuration files with hashed passwords.

The error message `ERROR 1049 (42000): Unknown database 'parking_guidance'` indicates that MySQL cannot find the database you are trying to access. Here's what you can do to resolve this issue:

1. **Check if the database exists:** Use the `SHOW DATABASES;` command to ensure that the 'parking_guidance' database is indeed not present in your current setup.

2. **Create the database:** If it doesn't exist, run the following command to create it:

   CREATE DATABASE parking_guidance;

3. **Grant privileges:** If you have not already done so, you'll need to grant privileges to your user account to access this new database. For example:

   GRANT ALL PRIVILEGES ON parking_guidance.* TO 'your_username'@'localhost' IDENTIFIED BY 'your_password';

Replace 'your_username' and 'your_password' with your actual MySQL credentials.

4. **Switch to the new database:** After granting privileges, use `USE parking_guidance;` to switch to the newly created database.

5. **Confirm connection:** Double-check that you can connect to the 'parking_guidance' database without any errors by running a simple query.

If you've already created the database and granted privileges, check for typos in the database name or user credentials. Make sure they match exactly as you specified them.
