Please do not cross-post..

If the data is in 2 schemas, as long as the logged in user has rights to each schema's tables it is much simpler than you tried..:

Select s.study.r.report_type
from schemaA.study s, schemaB.report r
where s.study_id = r.study_id Received on Thu Oct 07 2004 - 14:22:51 CDT
