I have two files: TOMH/LOCNMSTRPF, ADP/LOCNMSTRPF - both the same layout
and field names (the TOMH file is a backup of the ADP file). Key field for
each is called LOCN. For all records in ADP/LOCNMSTRPF, I want to update
one field ("printer") with data from the corresponding record/field in
TOMH/LOCNMSTRPF. I've tried the following SQL, but I'm getting an error:
update adp/locnmstrpf set printer=(select a.printer from tomh/locnmstrpf a,
adp/locnmstrpf b where a.locn=b.locn and a.printer<>' ' and b.printer=' ')
The error is: Result of SELECT more than one row.
Well of course it is. I know I can use RPG to do what I want, but I'd like
to know how to accomplish the same thing using only SQL. There is a way to
do this, right?
