SELECT BRAND_NAME,MODEL_NAME FROM TYPE left outer join MODEL on MODEL_PK =TYPE.MODEL_FK left outer join BRAND on BRAND_PK =MODEL.BRAND_FK group by BRAND.BRAND_NAME,MODEL_NAME having count(*)>1 intersect SELECT BRAND_NAME,MODEL.MODEL_NAME FROM TYPE left outer join MODEL on MODEL_PK =TYPE.MODEL_FK left outer join BRAND on BRAND_PK =MODEL.BRAND_FK where TYPE_NAME='xyz' group by BRAND.BRAND_NAME,MODEL_NAME -- Regards/Gruß, Tarlika Elisabeth Schmitz -- Regards/Gruß, Tarlika Elisabeth Schmitz
