我想使用准备好的语句使用python将数据插入MySQL DB（版本5.7），但是我一直收到NotImplementedError。我在这里关注文档：https : //dev.mysql.com/doc/connector-python/en/connector-python-api-mysqlcursorprepared.html

使用python-2.7和mysql-connector-python库的8.0.11版本：

pip show mysql-connector-python
---
Metadata-Version: 2.1
Name: mysql-connector-python
Version: 8.0.11
Summary: MySQL driver written in Python
Home-page: http://dev.mysql.com/doc/connector-python/en/index.html

这是我正在运行的python脚本的清理后的版本（没有特定的主机名，用户名，密码，列或表）：

import mysql.connector
from mysql.connector.cursor import MySQLCursorPrepared

connection = mysql.connector.connect(user=username, password=password,
                                      host='sql_server_host',
                                      database='dbname')
print('Connected! getting cursor')
cursor = connection.cursor(cursor_class=MySQLCursorPrepared)
select = "SELECT * FROM table_name WHERE column1 = ?"
param = 'param1'
print('Executing statement')
cursor.execute(select, (param,))
rows = cursor.fetchall()
for row in rows:
    value = row.column1
print('value: '+ value)

运行此命令时出现此错误：

Traceback (most recent call last):
