如何从Native SQL读取包含多个字段的SQL

import mysql.connector

# 连接数据库
cnx = mysql.connector.connect(user='username', password='password',
                              host='localhost', database='database_name')

# 构建SQL查询语句
query = "SELECT field1, field2, field3 FROM table_name"

# 执行SQL查询
cursor = cnx.cursor()
cursor.execute(query)

# 处理查询结果
results = []
for (field1, field2, field3) in cursor:
    result = {
        'field1': field1,
        'field2': field2,
        'field3': field3
    }
    results.append(result)

# 关闭数据库连接
cursor.close()
cnx.close()

# 打印查询结果
for result in results:
    print(result)
