Problems with PostgreSQL DBI-Link / DBD-ODBC

["Pit M." <fmi-soft@xxxxxx>]

I have the following problem with PostgreSQL and hope you guys can help 
me out in this matter: I try to get a remote connection to any database 
(e.g. MS-SQL or MS Access) using DBI-Link and DBD:ODBC. My problem is, 
that everything seems fine so far, however I don't know how to use the 
parameters for "make_accessor_functions()". I searched the net for it, 
but can only find samples for Perl-Scripting, but I need a sample for 
using it directly in SQL.

This is what I've come up so far. Hope you can point me to the right 
direction.

SELECT make_accessor_functions(
    'dbi:ODBC:Northwind::dbi_link.data_source,
    'sa'::text,
    NULL::text,
    '---
AutoCommit: 1
RaiseError: 1
'::dbi_link.yaml,
    NULL::dbi_link.yaml,
    NULL::text,
    NULL, ::text,
    'Northwind'::text
);


I have a ODBC connection named "Northwind".

The error message I'm always receiving (for the MS-SQL sample) is:

ERROR: error from Perl function: error from Perl function: duplicate key 
violates unique constraint "dbi_connection_data_source_key" at line 94. 
at line 35.
SQL state: XX000

I'm using following components under Windows XP
postgresql-8.2.5-1
pgadmin3-1.8.0
DBI-1.59
dbi-link-2.0.0
DBD-ODBC-1.05

Thanks in advance.
