Problems with ORACLE - Mailing list pgsql-odbc

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???
