Pyodbc连接给出奇怪的错误

Question

I am getting strange error while trying to connect to Teradata from Python Pyodbc.

The code i used

import pyodbc
pyodbc.pooling=False
conn=pyodbc.connect('DRIVER={ 
TeradataDriver16.20};DBCNAME=DBCNAME;UID=user_id;
PWD=Password;QUIETMODE=YES;database=databse;')

The above connection is successful. Now I am trying to run the below query

cursor = conn.cursor()
cursor.execute("SELECT TOP 10 * FROM DB_NAME")
tables = cursor.fetchall()    

This results in following error

Error: ('HY000', '[HY000] 䑛瑡䑡物捥嵴佛䉄⁃楬嵢唠楮潣敤挠湯敶瑲牥戠晵敦\u2072

\x00\x00\x00\x00\x00\x00(\x00\x00\x00 (0) (SQLExecDirectW)') 

Any pointers in solving this would be appreciated.

I cannot recreate your error with pyodbc. Could you try Teradata's own official package 'teradata' and see if you get similar behaviour.

pip install teradata

And then

import teradata

udaExec = teradata.UdaExec (appName="HelloWorld", version="1.0",
            logConsole=False)

with udaExec.connect(method="odbc",system=DBCNAME,  
                     driver="TeradataDriver16.20",
                     database=DBCNAME, username=user_id,
                     password=Password) as session: 
    for row in session.execute("SELECT TOP 10 * FROM DB_NAME"):
        print(row)
