Um, can you provide some insight into your schema?  We sniff at the
data types returned by Oracle, and try to do the right thing.  The
general number type format is:


where 'p' is the precision (total number of digits) and 's' is the
scale (or number of digits to the right of the decimal).  If 's' is
*not* zero, then we return a floating point, otherwise we try and get
Python int v. long right (basically if p > 9, then long).

I wonder if you just are using the Oracleism of NUMBER by itself,
which is hard to know what it will return.

Well, this is an Oracle issue, not a DCOracle issue.  Oracle 8/8i run
fine with shared libraries on: Linux, Solaris and HP-UX, we don't have 
an AIX box around here to test on, but I know that at some point in
the past, shared library support on AIX w/python was not correct.
