Oracle Thin Client Error when Inserting

Question

Cold Fusion 8 fully patched on Windows Server 2008 fully
patched
Oracle 8.1.7.1 on Linux as DB with Network Option
(encryption)
Oracle Client 10.2.0.3 Thin Client (tried with ojdbc14 and
ojdbc12 classes)
SELECT, DELETE, UPDATE statements all work just fine.
When an INSERT statement is sent to the DB it is processed
(the insert is made and committed!) but we are getting a database
error message "Typlänge größer als Höchstwert"
which translates approximately to typ length is larger than the
limit.
Several threads show this as a problem when the return from
the db is too large but this is definately not the case (a simple
insert of one small row).
The SQL that is run at the DB includes a suffix of "RETURNING
ROWID" which is not part of our SQL and is apparently added by CF
or the thin client. We do not handle the return value (we tried but
that did not help either).
Due to the fact that the INSERT is actually made and
committed, we assume the problem must be at the client end and not
in the database.
This is a blocking problem and appears to be confined to CF 8
with the Thin Client.
CF 8 with an ODBC connection to the same DB works OK.
Be very glad for any help as we want to go to production with
this environment.
Cheers

I noticed in LiveDocs for
cfquery
for CF 8 that the
result parameter is a little different than described for
CF7 in that it mentions the ROWID being returned for Oracle insert
statements.
What happens when you try including a result parameter (even
if you don't end up using the result_name.ROWID variable)?
result Optional Name for the structure in which cfquery
returns the result variables. For more information, see Usage.
The cfquery tag also returns the following result variables
in a structure. You can access these variables with a prefix of the
name you specified in the result attribute. For example, if you
assign the name myResult to the result attribute, you would
retrieve the name of the SQL statement that was executed by
accessing #myResult.sql#. The result attribute provides a way for
functions or CFCs that are called from multiple pages, possibly at
the same time, to avoid overwriting results of one call with
another. The result variable of INSERT queries contains a key-value
pair that is the automatically generated ID of the inserted row;
this is available only for databases that support this feature. If
more than one record was inserted, the value can be a list of IDs.
The key name is database-specific.
result_name.ROWID Oracle only. The ID of an inserted row.
This is not the primary key of the row, although you can retrieve
rows based on this ID.
I have a hunch that there are differences between Oracle 8i
and 10g in how the rowid value is being "returned".
