I want the criteria like this.

I have 10k of rows in my table and i have to fetch first 200 rows . And
next time when i execute the same query it should fetch next 200 rows
and that should be continued .For that is there any query for my
requirement or I have to write a dynamic sql procedure for this .

In Oracle using rowid we can get the records dynamically where as in
DB2 is the facility is there or not ?

Give some guidance regarding my requirement.
