[Zope] ODBC - 1 step forward - woops I tripped

[rgines@purina.com]

My client runs IBMs' UDB 5 database engine on OS/2 Servers with
NT clients (their choice not mine).   I'm a newbie with Zope and wanted to
understand the ODBC very well before trying to tie into UDB5 (since
my guess is that I am the first one stupid enough to try this).

So I started with something real simple.   A text file with four columns
and three records.

I can create an ODBC connection through Zope with no problem.
Going to the browse tab in the management screen actually
shows me the table with the column definitions ... so I am getting
from Zope, through the ODBC connector, through the WinNT
ODBC drivers to the text file.  Cool!

=======

Now to do real work, I create a DTML Method with the following

     <!--#var standard_html_header-->

     ....

     <dtml-in ZopeODBCTest>
       <dtml-var LAST_NAME>
     </dtml-in>

     <!--#var standard_html_footer-->


Running the 'View' returns the following result

Zope has encountered an error while publishing this resource.

           Error Type: AttributeError
           Error Value: __len__

So I ran grep on all the *.py files thinking that this might
be a rare name ... woops.    I'm still trying to figure out
DTML and haven't dove into Python yet.   Debugging
the python code (or searching for my erroneous ways
is still a week or so off .... if not more).

======

Assuming that my incredibly complicated code is buggy
(proof reading three lines of code is tough), I decided to
create a Z SQL Method with the following SQL.

     select * from ZopeTest

Well I did and I get this result when running it.

Error, sql.error: ('S1000', -1032, "[Microsoft][ODBC Text Driver] The
Microsoft Jet database engine cannot
open the file 'ZopeTest.txt'. It is already opened exclusively by another
user, or you need permission to view its
data.")


Hmmm. Access issues?   I'm logged on as a local Admin

Already openned?   The ODBC Connector gets there fine to read the tables
(or is it just reading the
schema.ini? ... not sure yet).   Nothing else that I know of has it
openned.   ... no network locks, this
is all done on a local system at this point.

=======

So much for connecting to a real database, I can't even get to a text file.

Any pointers (pointing out my stupidity) or assistance  would be greatly
appreciated.   Gracias.
