我正在尝试使用Jaydebeapi连接Mac 10.14.2 中的Teradata数据库。我收到以下错误。早些时候，我在安装Jaydebeapi时遇到了问题。经过大量的试验和错误。我将 Python 3.7 降级为 Python 3.6。以下是代码和相应的错误输出

代码

import sys
import os
import string
import jaydebeapi
from time import gmtime, strftime
from datetime import datetime, timedelta
case_detail_server ='*******'
amanita_server= '******'

database_case_detail='CASE_DETAILS_APP'
user_case_detail='****'
password_case_detail='!****'
jars= ['/Users/AppleUser/anaconda3/envs/py36/lib/tdgssconfig.jar','/Users/AppleUser/anaconda3/envs/py36/lib/terajdbc4.jar']
jclassname_case_detail='com.teradata.jdbc.TeraDriver'
case_detail_url='jdbc:teradata://xyz/DBS_PORT=1025,TMODE=ANSI,CHARSET=UTF8'

conn_case_detail=jaydebeapi.connect('com.teradata.jdbc.TeraDriver',case_detail_url,{'user': user_case_detail, 'password': password_case_detail},jars)
curs_case_detail = conn_case_detail.cursor()

curs_case_detail.execute("SELECT TOP 100 Case_Id, Case_Type_Desc FROM aca.fact_case_detail ")

错误

我重新检查了所有数据库名称和 url。发现一切都是正确的。然后，我从这里重新下载了 Teradata JDBC 驱动程序：

https://downloads.teradata.com/download/connectivity/jdbc-driver

jars=['/CorrectPath/tdgssconfig.jar','/CorrectPAth/terajdbc4.jar']

打开包装并给出了新的路径。并发现它正在工作。

奇怪的！但是，我得到了解决方案。:)
