Python 连接到 Hive

Question

我安装了 Hortonworks Hive ODBC 驱动程序并在数据源中创建了一个连接。我测试了它，它成功地工作了。

我安装了PyODBC，写了下面的代码

import os, sys, pyodbc;
con = pyodbc.connect("DSN=MyCon")

我收到错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.Error: ('HYC00', '[HYC00] [Hortonworks][ODBC] (11470) Transactions are not supported. (11470) (SQLSetConnnectAttr(SQL_ATTR_AUTOCOMMIT))')

我也试过了

import pyodbc, sys, os
pyodbc.pooling = False
pyodbc.autocommit = False
con = pyodbc.connect("DSN=MyCon")

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.Error: ('HYC00', '[HYC00] [Hortonworks][ODBC] (11470) Transactions are not supported. (11470) (SQLSetConnnectAttr(SQL_ATTR_AUTOCOMMIT))')

也试过

con = pyodbc.connect("DSN=Tenet", autocommit=False)


Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.Error: ('HYC00', '[HYC00] [Hortonworks][ODBC] (11470) Transactions are not supported. (11470) (SQLSetConnnectAttr(SQL_ATTR_AUTOCOMMIT))')

Answer 1

我解决了.....我不会删除我的问题并将答案放在这里

pyodbc.autocommit = True
con = pyodbc.connect("DSN=MyCon", autocommit=True)

这是根据这篇文章的建议完成的
