Hi all,

How do I forumlate the below query without using the UNION clause?

SELECT H1.OID HISTORIEOID,FAHRZEUG.AMTLICHESKENNZEICHEN,
FAHRZEUG.OID,
H1.PRODUKT,H1.AUFTRAGSPOSITIONSNR,H1.MYTECHOBJEKT
FROM FAHRZEUG,HISTORIE H1
WHERE FAHRZEUG.OID = H1.MYTECHOBJEKT(+)
AND TO_DATE(H1.DATUMSTR,'YYYY-MM-DD') = (select
max(TO_DATE(H1.DATUMSTR,'yyyy-mm-dd'))
from historie ,FAHRZEUG WHERE FAHRZEUG.OID = HISTORIE.MYTECHOBJEKT AND
HISTORIE.MYTECHOBJEKT=H1.MYTECHOBJEKT)
AND H1.PRODUKT IN('HU', 'AU')
UNION
SELECT H1.OID HISTORIEOID,FAHRZEUG.AMTLICHESKENNZEICHEN,
FAHRZEUG.OID,
H1.PRODUKT,H1.AUFTRAGSPOSITIONSNR,H1.MYTECHOBJEKT
FROM FAHRZEUG,HISTORIE H1
WHERE FAHRZEUG.OID = H1.MYTECHOBJEKT(+) AND H1.PRODUKT IN('DS', 'NFZ',
'BES', 'DekraSiegel', '700000', '700202');

I can't use the union clause because I am using an Object-Relationship tool
called Cocobase which doesn't support the UNION clause.  Any help in this
regard is very much appreciated.

Thanks and Regards,

Ranganath
