大家好我现在正在使用Pandas和MSSQL。我有好的工作,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,我收到以下错误

pyodbc.Error :(' HY000','驱动程序未提供错误!')

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)

我得到的完整错误就是这个

Traceback (most recent call last):

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

上述异常是导致以下异常的直接原因:

我曾尝试回滚到较低版本的SqlAlchemy,在Windows中更新ODBC驱动程序并升级python安装并继续回来。

有关如何解决此问题的任何想法?

好的,这是“pandas 23中已知错误的无声错误,降级到v22会导致错误消失,您可以上传1000多行。

答案 1 :(得分:0)

我有相同的错误(“ HY000”,“驱动程序未提供错误!”)。一些StackOverflow线程上的现有解决方案没有帮助。

就我而言,错误来自pyodbc.connect()

我最终重新安装了python和依赖项,问题消失了。

答案 2 :(得分:0)

pyodbc.connect('Driver={ODBC Driver 17 for SQL Server};')

换司机对我有用!
