Hi,
Can you please give the answers for these questions.


1. When we use select in DB2 whether it will collect a set of records.Is it to avoid this we are using cursor,ie to fetch 1 record at atime.
How all we can define cursor,is it possible through Working- storage section and procedure division.What is the difference between two?
2.While we are defining a GDG we are using the term (chronolagical ly and functionally related datasets)what is meant by chronological .

Yes to Process all the record return by query we use cursor & there is no
difference between cursor defining in Working- storage section and procedure division But it should always define before OPEN Cursor stmt

Thanks Ekta...

Regarding 2nd question..
When we try to explain a GDG we will define it as "group of datasets which are chronologically and functionally related".In this what is the significance of the word 'chronological'.

regards,
indu

The term 'Chronological' means order of occurence.In case of GDG you can see that the versions are in an order.For example,you have a daily updated GDG ,then the latest version will be today's data and previous version will be yesterday's data and so on..

Thanks,
Muthuvel.
