        database='your_database'
    )

    # Create a cursor to perform database operations
    cursor = db_connection.cursor()

    # Execute the INSERT statement which may cause duplicate entry error
    insert_query = "INSERT INTO your_table (id, name) VALUES (1, 'John Doe')"
    cursor.execute(insert_query)

    # Commit the changes if no error occurred
    db_connection.commit()

except mysql.connector.Error as error:
    if error.errno == 1062:  # Error code for duplicate entry violation
        # Handle duplicate entry error
        print("Duplicate entry: The primary key already exists.")
    else:
        # Handle other database errors
        print("Database error:", error)

finally:
    # Close the cursor and database connection
    if cursor:
        cursor.close()
    if db_connection:
        db_connection.close()
