使用这个基本的 read_csv 和 to_sql 脚本时，我得到以下错误代码。有人可以解释一下我的系统做错了什么。我曾经工作过，但过了一段时间我收到了这些错误消息。我还查看了我的 MySQL 数据库，但它也可以上传 varchar(256)。

import sqlalchemy
import mysql.connector
import pandas as pd


engine = sqlalchemy.create_engine('mysql+pymysql://boaz:............./Boaz', pool_recycle=3600, echo=False)
connection_alchemy = engine.connect()

filename = r'C:\Users\Bkuijer\Documents\contact details.csv'

df = pd.read_csv(filename, delimiter=';', encoding='utf-8')

print(df)

df.to_sql('Proef', con=engine, index=False, if_exists='append')

  result = self._query(query)
