python - Python SQLAlchemy pyodbc.Error: ('HY000', '驱动程序没有提供错误！')

问题描述

大家好，我现在正在使用 Pandas 和 MSSQL。我工作正常，但最近在 SQlalchemy 更新后，当我尝试通过 df.to_sql 将信息上传到数据库时出现以下错误

pyodbc.Error: ('HY000', '驱动程序没有提供错误！')

我的连接定义如下

engine = create_engine('mssql+pyodbc://Reporter:******@localhost:1433/SourcingDb?driver=SQL+Server')

df.to_sql('ProductivityDeck', con=engine, if_exists='replace', index= False)

我得到的完整错误是这个

Traceback (most recent call last):

文件“C:\Python\Python36\lib\site-packages\sqlalchemy\engine\base.py”，第 1182 行，在 _execute_context 上下文中）文件“C:\Python\Python36\lib\site-packages\sqlalchemy\engine\ default.py"，第 470 行，在 do_execute cursor.execute(statement, parameters) pyodbc.Error: ('HY000', '驱动程序没有提供错误！')

上述异常是以下异常的直接原因：

    cursor.execute(statement, parameters)

我试图回滚到较低版本的 SqlAlchemy，更新 Windows 中的 ODBC 驱动程序并升级 python 安装，它不断回来。

有关如何解决此问题的任何想法？

解决方案

好的，对于 pandas 23 中的一个已知错误，这是一个“静默错误，降级到 v22 会使错误消失，您可以上传 1000 多行。
