If I understand it right you need a count for every day in interval records.
I think, that the easiest way how to get right numbers (it's not much
sophisticated, but ...) is:
1. create table day_count( day_id number, day_nbr number );
2. fill table day_count with tuples where day_id starts at 1 and goes up to
max( eday of your source table), day_nbr is 0.
3. for every tuple in your source table do: update day_count set day_nbr :=
day_nbr +1 where day_id >= sday and day_id <=eday;
4. simply select
