Week Comparison

Question

Dear All,
I have two tables Project P and Project_allocation_details PAD .
P has budgeted hrs and PAD which has from and to date date fileds and budgeted hrs.
For example in
Table P has a project starting from 10/10/2002 with 10hrs/week
In PAD, from date 10/10/2002 , to_date = null and budgeted hr =10 means the allocation for the project is ongoing without an end with 10 hrs weekly.
I need to check each day that the current week has allocation of 10 hrs from the above PAD table ??
Whether I need to add Year as well in my select statement ?? As the dates can be in different Years ,how to do that ??
How to do that ?? Can you please help
Thanks
SJ

I'm afraid I am unable to unbderstand what it is you are trying to achieve. Some table descriptions and some sample data would help.
My sample strikes me as being too simplistic but I am at a loss to know what more you want. What do weeks have to do with anything?

CREATE TABLE prj (pid number, start_date date)
CREATE TABLE pad (pid number, start_date date, end_date date, budget number)
INSERT INTO prj VALUES (1, to_date('02-02-2002', 'DD-MM-YYYY'))
INSERT INTO prj VALUES (2, to_date('02-07-2002', 'DD-MM-YYYY'))
INSERT INTO pad VALUES (1, to_date('02-02-2002', 'DD-MM-YYYY'), to_date(null), 10)
INSERT INTO pad VALUES (2, to_date('02-07-2002', 'DD-MM-YYYY'), to_date('01-01-2003', 'DD-MM-YYYY'), 10)
INSERT INTO pad VALUES (1, to_date('02-01-2003', 'DD-MM-YYYY'), to_date(null), 20)
