David, I have talked with the people of Oracle and they told me that:
El problema radica en la diferencia del comportamiento default de los simbolos, Oracle transforma todo a mayusculas, postgres a minusculas.
En el momento de resolver la query, esta se transforma en
select field from table@link
-> select "A1"."FIELD" from "TABLE" A1
Como el ultimo alias posgres lo transforma a minusculas este es equivalente a
-> select "A1"."FIELD" from "TABLE" "a1"
El cual no puede resolver.
TRANSLATING:
THE PROBLEM IS THE DIFFERENT BEHAVIOR OF THE DEFAULT SIMBOLS, ORACLE TRANSFORMS EVERYTHING TO UPPERCASES, POSTGRES TO LOWECASES.
WHEN THEY TRY TO RESOLVE THE QUERY ITS´ TRANSLATE FROM:
TO:
TO SELECT "A1"."FIELD" FROM "TABLE" A1
BECAUSE THE LAST ALIAS POSTGRES TRANSLATES TO LOWERCASE THIS IS EQUIVALENT TO:
SELECT "A1"."FIELD" FROM "TABLE" "a1"
THE WICH ONE CANNOT BE RESOLVE.
THEY ARE ASKING ME IF THERE IS A WAY TO CHANGE THIS BEHAVIOR.
You have already told me that there is not a way around so they are going to declare this as a bug.
Using Oracle 8.1.6 I was never successful in accessing a PostgreSQL database. Examination of the log files revealed that the Oracle ODBC driver uses double quotes "" inconsistently creating and then calling a table alias. There was no way around this, so it was impossible to access the PostgreSQL database from Oracle. I posted these findings on the OTN Heterogeneous Services discussion group and was told I needed to contact Oracle support. I moved on to other projects and I have not tried again with later versions of the Oracle ODBC driver. If you find a way to get Oracle to talk to PostgreSQL please let me know.

Hi, when I use the psqlODBC with MS-Access I´ve got not problems but when I try to use it with Oracle the next message appears:
SELECT * FROM "ORACLE"."TABLITA"@POSGRES
*
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this
message:
[Generic Connectivity Using ODBC]Record &SQLREC has no fields. Loading failed
ORA-02063: preceding 2 lines from POSGRES
Altougth I´ve got already fields in the tables, I´ve tried with differnt kind of datatypes varchar char int numeric....but the problem persist
Any Idea???
Thanks in advance
