Answer 1

i am not very good at rollup and grouping :-(, but i used analytics hope this can give you some hints and you can accommodate "break" in there,
Create Table test As
Select 1 X_id , 'a' y_id, to_date('11/12/2006','dd/mm/rrrr') "Day" From dual Union All
Select 1, 'a', to_date('11/12/2006','dd/mm/rrrr') From dual Union All
Select 1, 'p', to_date('11/12/2006','dd/mm/rrrr') From dual Union All
Select 1, 'a', to_date('3/12/2006','dd/mm/rrrr') From dual Union All
Select 1, 'p', to_date('3/12/2006','dd/mm/rrrr') From dual Union All
Select 2, 'a', to_date('11/12/2006','dd/mm/rrrr') From dual Union All
Select 2, 'p', to_date('11/12/2006','dd/mm/rrrr') From dual
