Holidays inconsistency

Question

hi all,
i've the following problem: i've a table called holiday_tab as follows:
hol_serial hol_desc hol_date hol_days --------------------------------------------------------------------- the above table contains the dates of the official dates but doesn't contain weekend dates.
when employee take a holiday for 30 days for example i've to calculate only the working days not including weekends and official holiday..how can i avoid calculating the holiday twice if for example 20/1 is weekend and also it is official holiday i want only to let working days=29 instead of 28

Answer 1

Yeah, I thought of a better way.
Lets say you have a structure containing the official_holidays . Let's say it is a table off_hol (off_date date).
For a specific holiday, (hol_days div 7) should give the number of weekends contained in the holiday.
So.
declare
v_off_days pls_integer;
hol_days_no pls_integer;
begin
--count the offical holidays which are not in a weekend
Select count(off_date)
into v_off_days
from off_hol
where off_date between (hol_date, hol_date + hol_days)
and to_char(off_date,'DAY') not in ('SATURDAY','SUNDAY');
-- * 2 'cause I supposed Saturday and Sunday is free. :)
hol_days_no := hol_days -
(hol_days div 7) * 2 - v_off_days;
end;
Surely this one looks better.
