The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Maybe, but in this case, UNION is still the right way to go... Why bother to have to map to the correct field when a union will combine the two initial datasets into one result...

Subject: RE: can this be done with SQL - a record is one file or the
other
I suppose, in the not too distant future, you could run:
select
case when hdvoucher is null then advoucher else hdvoucher
end as voucher,
case when hdvendor is null then advendor else hdvendor end
as vendor,
case when hdinvoice is null then adinvoice else hdinvoice end
as invoice,
case when hdpostingdate is null then adpostingdate else
hdpostingdate end as postingdate
from qtemp.apohd full outer join qtemp.aphhd
on hdvoucher=advoucher and (
hdvoucher=1235 or advoucher=1235)
