Re: Oracle Heterogenous Services Error

Sorry to step into this so late, but when I saw that you were using oracle 10g I
did not think it relevant. Please see the attached set of emails exchanged a few
years back regarding this topic, and a TAR that Oracle says they have completed.
Since my initial effort I have not again attempted to use Oracle HS with
PostgreSQL.

Yes I do the TAR númber is: 13953728.6

We are in touch (I hope they release the patch soon, while, the systems area in
my company are going to develope a kind of non real-time "replication" program.

Greetings

Alejandro.

Thank you so much for forwarding this information. The fix for them is simple.
Have the ODBC translation layer either always use double quotes or never use
them. If you have a TAR number from oracle I would appreciate knowing it so I
can find out when this problem is resolved. As it turns out, the future project
I was exploring the Oracle to PostgreSQL communications link for is happening
now. ODBC would certainly make things easier.

Thanks again.

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:
SELECT FIELD FROM TABLE@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.

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

As I said before. psqlODBC get PGADMIN instead of pgadmin. There are two ways:
1) say Oracle to don't uppercase the username
2) create PGADMIN user in postgresql backend - to create this
   user you have to spcify the username in double quotes
   (somethink like this: create user "PGADMIN").

It isn't psqlODBC problem.
