Answer Posted / abhishek bajpai
It is not mandatory to use OVRDBF(*Yes) before OPNQRYF. You
can still use OPNQRYF without OVRDBF.
But here the pupose of the OPNQRYF won't be solved.
Opnqryf creates its own Open data path and to share the
same data path in a program we use ovrdbf share(*yes), if
we do not use ovrdbf, then program will have its own ODP,
so it will read the file from begining on which query has
been run. So, OPNQRYF selected records will have no
importance.
So, we need to use CPYFRMQRYF command and put the selected
records in to runtime file and use that file to read in
program.
