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.
Use a Common Table Expression to order file 1 in the preferred sequence,
then join to the CTE, returning the matched rows as one long record that
is mapped into two data structures then make comparisons between the
two data structures ?

Subject: sql v opnqryf
Hi all,
I want to compare two files : the results of a test against the results of the last test. We have an old home utility that generates an rpg matching record program. When there are key fields in both ascending and descending order, we use opnqryf in a clp that calls the rpg to temporarily reorganize the files so that matching will work.
How could this be done in sql?
Thanks
