Replace "your_database_name", "your_username", "your_password", "your_host", and "your_port" with your actual database credentials.

Remember to replace the placeholder values with your actual database credentials and customize the table name and columns according to your specific schema. This example assumes a direct connection; for production environments, consider using environment variables for sensitive information and error handling for robustness.
