[DB-SIG] Oracle interface for Windows/NT

The ODBC module has been used extensively against Oracle databases,
including the use of dates and raw values. It was quite capable and had
everything needed. It is certainly more straightforward than trying to
use oracledb on NT, which I seriously doubt anybody has done, which
means that you'd be working with something even less stable than the
ODBC module. I believe mxODBC was intended for Unix platforms. Since it
uses the same interface as the win32 ODBC module, I don't see that it
would actually provide any additional benefit, and it, too, has
certainly been used less than the win32 ODBC module.
In any case, just try it. If you run into problems, then come back here.
As Bill said, he'll gladly help out with questions. Others here will,
too, I'm sure.

Thank you for your reply. I have still not heard from anyone
actually got your oracledb module working under Windows/NT.
At your suggestion I tried the dbi and odbc modules in Pythonwin. The
documentation of these is obscure, but eventually I came upon it.
the description of the bugs and limitations and the lack of anyone
using/supporting it was not a happy discovery. I am certainly able to
connect to the oracle database and do some simple things. Have not yet
figured out what to do about date/time and raw data types. If I could
locate others using either oracledb or the mxODBC module I would feel
comfortable using one of them - but looks like I have to build one or
of oracledb or mxODBC myself - as an extension module.
In reference to this you talk about an NT-specific make file? Are you
assuming I will have to import the gnu tools and compiler to my NT
not use the Microsoft Visual C++ environment, for example? As I said in
first mail I really have no clue what I am doing on NT and don't
want to go deeply into it. So once again - please someone - share your
ready-built and ready-to-run Win32 oracledb or mxODBC module with me if
have already done this. Or at least your 10 step recipe. Also let me
who else is using the built-in dbi and odbc in PythonWin. Has anyone
any of the known bugs?
Thanks a lot in advance
Also - I think someone should remove the oramod stuff from the web pages
archive. The only files that seem to be there are patches. These date
1995 and the web page associated with the product says the author has
abandoned it. It is simply confusing to people to have out-of-date and
usupported stuff offered in the Python archives.
