[cx-oracle-users] Supporting multiple Oracle Client versions on Win32

[Harry F. <hf...@gm...>]

Hoping for a bit of advice and apologies up front if this is a dumb
question (it may be).

Have an executable Python app built with py2exe that uses cx_Oracle
(currently one of the binary versions built for Oracle 8.x). Now in a
situation where I need to support both the Oracle 8.x client and the
9.x client (some users have 8.x, others have 9.x).

Is there a way I can do this at runtime i.e. detect the Oracle client
version and load the correct cx_Oracle version? Guess that implies
having multiple versions of the Oracle client and cx_Oracle installed
on the PC where I build the app with py2exe. What I'm hoping to
provide a single executable that will work for all Oracle client
versions.

Many thanks,

Harry
