Linked Object to SQL-View to Oracle Table through MSDAORA

wakestar

Following situation:
SQL-Server 2000
Linked Server to Oracle through MS OLE DB Provider for Oracle

SQL-Server throws an Error when trying to show records in SQL Enterprise Manager:
'IRowset::GetNextRows' returned 0x80004005...

The sql view looked like:
SELECT Fieldname, Fieldname2
FROM ORACLESERVER..NAVISION.SOMETABLE

After changing the sql view to
SELECT *
FROM OPENQUERY(ORACLESERVER, 'SELECT Fieldname, Fieldname2 from NAVISION.SOMETABLE')

the error message disappeared and the Enterprise Manager now shows the records.

The funny thing is that
- the first view worked before and *suddenly* stopped working ..( at least that's what the client says)
- this error only appears when the oracle table is empty (both sql views work correctly when records exist on the oracle side)

Any explanations?
My guess is: buggy msdaora

Could it be because of a .NET upgrade?

Microsoft .NET Framework 3.5 SP1 - Update "KB963707" was installed... 1st of july :-k :-k :-k


Now i'm getting a new error since I have switched to OPENQUERY:

'MSDAORA' IRowsetChange::SetData returned 0x80004005

SQL:
UPDATE NAVISION.SOMETABLE WITH (REPEATABLEREAD) SET .....

When the users tries to modify the table from navision

Is there a way to get rid of the 'REPEATABLEREAD' and replace with something similar which Oracle accepts?

I can't modify the oracle data at all.. (with or without OPENQUERY)
