Re: Problems with ORACLE

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(at)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:
SELECT FIELD FROM TABLE(at)LINK <mailto:TABLE(at)LINK>
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.

Asunto: Re: [ODBC] Problems with ORACLE

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.

Subject: [ODBC] Problems with ORACLE

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
