Calculating total of days

Question

Hi Everyone,
I have 2 date items:
p9_begin and p9_end
I want to show all the sundays between these two days and also the total of sundays.
I also want to show the total of days minus the sundays.
I can't seem to think of a solution to do this. I tried to loop, but it doesn't seem to work correct.
Does anyone have a suggestion?
Regards,
Diana

Hi Diana,
You could do something like:
WITH X AS (SELECT TO_DATE(:DATE1,'DD/MM/YYYY') + LEVEL - 1 THE_DATE FROM DUAL CONNECT BY TO_DATE(:DATE1,'DD/MM/YYYY') + LEVEL - 1 < TO_DATE(:DATE2,'DD/MM/YYYY'))
SELECT (SELECT COUNT(*) FROM X WHERE TO_CHAR(THE_DATE, 'DY', 'NLS_DATE_LANGUAGE=ENGLISH') = 'SUN') SUNDAYS,
(SELECT COUNT(*) FROM X WHERE TO_CHAR(THE_DATE, 'DY', 'NLS_DATE_LANGUAGE=ENGLISH') <> 'SUN') OTHERDAYS
FROM DUALwhich would give you your Sundays/non-Sundays. Or,
WITH X AS (SELECT TO_DATE(:DATE1,'DD/MM/YYYY') + LEVEL - 1 THE_DATE FROM DUAL CONNECT BY TO_DATE(:DATE1,'DD/MM/YYYY') + LEVEL - 1 < TO_DATE(:DATE2,'DD/MM/YYYY'))
SELECT THE_DATE FROM Xwould give you all of the dates.
:DATE1 is whatever item contains your "From date" and :DATE2 is your "To date"
