You should put trans as your primary file, and then do an outer join, giving
you just the records you need.

Subject: Update "orphan" entries with SQL
I have a master file with the following keyfields:
mcono, mcust, mtickn, mdate
And a transaction file:
tcono, tcust, ttickn, ttdate, tprod, tunits, tsts
The transaction file matches to the master file:
mcono=tcono, mcust=tcust, mtickn=ttickn, mdate=ttdate
What I need to do is to update the tsts field to "O" if there is no matching
master entry for the transaction record. Here's what I have for the
selection:
select * from trans where not exists (select * from master where mcono=tcono
and mcust=tcust and mtickn=ttickn and mdate=tdate)
How do I adjust that so that I update the tsts field?
Thanks!
