Re: query question

Two queries is probably the easiest and most straight forward way.  Write
one query that selects the records desired (either the customers desired, or
the date ranges desired) and then write another query against that output
file to get the other datum needed (either the sales records or the customer
records).

Advantages of this method is that it is easily taught to your query user
base and it is not the hog for performance some of the monolithic queries
can be,

I dont think query is what you want here. I think you really need a
sort/merge. How about using OPNQRYF instead

Greetings,
I am trying to write a query that will pull data from several files. They
do have a common field that I will use for the selection, but joining the
files on that field of course results in extraneous records in the output. I
need some way to merge the data selected instead and then sort it by
customer and date.
This is what we are looking for as output for example:
charge account activity sorted by account # and date
Customer number Date1 Item1 Purchase amount
Date1 Item2 Purchase amount
Date2 Item1 Purchase Amount
Date3 Payment amount
Date4 Item1 Purchase amount
Date5 Payment Amount
Purchases and payment history are separate files with different fields and
formats.
Am I missing the obvious here or is it not possible to do this with query?
Thanks,
-doug
