Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. import pypyodbc.
2. try to connect.

What is the expected output? What do you see instead?
A connection object.

What version of the product are you using? On what operating system?
pypyodbc-1.0.11 / python2.7.2 / linux

Please provide any additional information below.
Fresh install.  All I'm trying to do is start a connection.  See log attached.  
I get the same error with MS-SQL (Driver SQL Server Native Client 11.0) as well.

Worth noting that this works fine with pyodbc

Same result with latest from Git.

Can you provide additional information, such as 64bit , 32bit information ?

Original comment by jiangwen...@gmail.com on 1 Apr 2013 at 10:50

GoogleCodeExporter commented 8 years ago 
Yep, 64bit CentOS 6.1 with 64-bit Python 2.7.2.

GoogleCodeExporter commented 8 years ago 
Also tried with 64-bit CentOS 6.3, RHEL 6.1 and Python 3.2.3.  All give the 
same error.

Can you check what would be the output if you add ansi=False?
conn = pypyodbc.connect('DRIVER={MySQL ODBC 5.1 
Driver};SERVER=myserver;DATABASE=mydb;UID=user;PWD=password',ansi=False,ansi=Fal
se,unicode_results=Fase)

Do you mean ansi=True?  False is default.  If I do =True, it connects ok, but 
then all my results come back encoded like:

u'\udc80\udc75\udc40\udc65'

conn = pypyodbc.connect('DRIVER={MySQL ODBC 5.1 
Driver};SERVER=myserver;DATABASE=mydb;UID=user;PWD=password',ansi=False,unicode_
results=False)

Gives me the same error...

conn = pypyodbc.connect('DRIVER={MySQL ODBC 5.1 
Driver};SERVER=myserver;DATABASE=mydb;UID=user;PWD=password',ansi=True,unicode_r
esults=False)

Still gives me unicode results.

And if you try and print one of the unicode results:

UnicodeEncodeError: 'latin-1' codec can't encode characters in position 0-3: 
ordinal not in range(256)

I will install a CentOS 64bit and try that.

Thanks!  Just so you get the same setup:

$ odbcinst --version

$ cat /etc/odbcinst.ini

It works fine on my Ubuntu box at home, so might well be a CentOS / RHEL issue.

Original comment by cyborg10...@gmail.com on 1 Apr 2013 at 8:10

GoogleCodeExporter commented 8 years ago 
is your ubuntu at home 64 bit?

Original comment by jiangwen...@gmail.com on 1 Apr 2013 at 11:18

GoogleCodeExporter commented 8 years ago 
Yes

Hi, Finally I'm not able to setup CentOS, so I would like to suggest two quick 
changes you can have a try.

First step:
-Open pypyodbc.py, text replace "if status == 0 and 'SQL_WCHART_CONVERT' in 
output:" to "if True:" .This will only make one change in Line 479.

Have a try.

Second step:
-If that doesn't work, text replace all "utf_16" to "utf_32" and all 
"utf_16_le" to "utf_32"

And then try again.

Hope that works.

The fist test results in:
>>> import pypyodbc
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/scratch/Python/lib/python2.7/site-packages/pypyodbc.py", line 518, in <module>
    raise OdbcLibraryError('Using narrow Python build with ODBC library '
pypyodbc.OdbcLibraryError: 'Using narrow Python build with ODBC library 
expecting wide unicode is not supported.'

And the second (with or without the first) results in the same issue as before.

This works fine on the same box with 3.3.1, so it could be an issue with 2.7.2.

2.7.4 has the same issue
