Python3.3.2 + pyodbc in Ubuntu 13.10 does not work #381

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Installed: python, python-dev, python3, python3-dev, g++, gcc, unixODBC, 
unixODBC-dev

2. Follow the steps in https://code.google.com/p/pyodbc/wiki/Building
  a. python setup.py build
  b. sudo python setup.py install

3. Try to exec a query:

$ python
Python 3.3.2+ (default, Feb 28 2014, 00:52:16)
[GCC 4.8.1] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyodbc
>>> pyodbc.version
'3.0.7'
>>> con = 
pyodbc.connect("DRIVER={NetezzaSQL};SERVERNAME=1.1.1.1;PORT=5480;DATABASE=dbname
;USERNAME=user;PASSWORD=pass")
>>> cursor = con.cursor()
>>> cursor.execute('SELECT MAX(CONNECT_TIME) FROM V_CONNECTION')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.ProgrammingError: ('42000', '[42000] ERROR:  \'S\'\nerror    ^ found "S" 
(at char 1) expecting a keyword (27) (SQLExecDirectW)')

What is the expected output? What do you see instead?

Expected output: query results (it works on Windows with python3+pyodbc and in 
this same Ubuntu server using python2.7+pyodbc).

However, it shows the following error:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.ProgrammingError: ('42000', '[42000] ERROR:  \'S\'\nerror    ^ found "S" 
(at char 1) expecting a keyword (27) (SQLExecDirectW)')

What version of the product are you using? On what operating system?

This is the result of the build, perhaps it is useful.

Same issue on Ubuntu 15.4 with Python 3.4 and latest PyODBC.

Same code works on windows under python 3.2.

wanted to follow up. In my case the ODBC driver (NetezzaSQL) was set to use 
UTF8. I first though the issue was either a UC2 or UC4 build of Python. Both 
made no difference. Switching the driver to UTF16 
(UnicodeTranslationOption=utf16) fixed the issue for me.
