唯一约束违反oracle错误。如何获取python中违规的insert语句？

import cx_Oracle

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

# 创建游标
cursor = connection.cursor()

# 执行插入操作
try:
    cursor.execute("INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')")
    connection.commit()
except cx_Oracle.IntegrityError as e:
    error = e.args[0]
    # 解析异常信息
    if error.code == 1:
        constraint_name = error.context.index_name
        violated_value = error.context.failed_value
        violated_columns = error.context.failed_column_names
        print(f"唯一约束 '{constraint_name}' 被违反。")
        print(f"违反约束的值为 '{violated_value}'。")
        print(f"违反约束的列为 {violated_columns}。")
    else:
        print("发生其他类型的完整性错误。")

# 关闭游标和连接
cursor.close()
connection.close()
