如何在数据存储中包含从oracle源到平面文件(目标)的列名？

import cx_Oracle
import csv

# 连接到Oracle数据库
connection = cx_Oracle.connect("username/password@hostname:port/service_name")

# 创建游标
cursor = connection.cursor()

# 执行查询语句
query = "SELECT column1, column2, column3 FROM table_name"
cursor.execute(query)

# 获取查询结果和列名
results = cursor.fetchall()
column_names = [desc[0] for desc in cursor.description]

# 导出数据到CSV文件
with open('output.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile)
    
    # 写入列名
    writer.writerow(column_names)
    
    # 写入数据
    writer.writerows(results)

# 关闭游标和数据库连接
cursor.close()
connection.close()
