Calculated columns to get difference between two dates with half day

Hi,
So there is the problem I'm using a calculated column to track the number of day when an employee make a vacation request. I'm already taking weekends of the case but now I would need to be able to ask for only a half day off.
How could I perform that without taking out my first requirement?
Just in case there is my current formula:
=IF(AND((WEEKDAY([EndDate],2))<(WEEKDAY([StartDate],2)),((WEEKDAY([StartDate],2))-(WEEKDAY([EndDate],2)))>1),(((DATEDIF([StartDate],[EndDate],"D")+1))-(FLOOR((DATEDIF([StartDate],[EndDate],"D")+1)/7,1)*2)-2),
Thanks for your answers :)

Hi amber,
you can simple calculate.
try this:
DATA: date1 like sy-datum,
date2 like sy-datum.
data I type i.
date1 = '20070301'.
date2 = '20070228'.
i = date1 - date2.
write: / date1, date2, i.
date1 = sy-datum.
date2 = sy-datum - 30.
i = date1 - date2.
write: / date1, date2, i.

i want to get difference between two date into text Item :P36_C in On Change java script.
i have two Date Item :P36_A and :P36_B .i have extract these date value from table then difference comes into Text Field :P36_C.
Now i want if i change Date into Item :P36_A or Item :P36_B then Defference between two date Should Come into Item :P36_C .
So i have use Java Script Code to do this
<script>
function diffdat(){
    function getVal(item){
   if($x(item).value != "")
     return parseFloat($x(item).value);
   else
     return 0;
    $x('P36_C').value =
getval((TO_DATE('P36_B', 'DD-MON-YYYY'))-
getval(TO_DATE('P36_A', 'DD-MON-YYYY')))+1;
</script>
i have put this into Item HTML Form Element Attributes
onChange="javascript:diffdat();"it's not woring .
How to work that Code with dates.
Thanks

You can always create your own difference function based on your own criteria. You can modify this to suit your needs.
CREATE OR REPLACE FUNCTION CALC_OFFICE_DAYS(date1 DATE, date2 DATE)
RETURN NUMBER
IS
v_begin_date DATE := date1;
v_end_date DATE := date2;
v_office_start_time VARCHAR2(10) := '09:30 AM';
v_office_end_time VARCHAR2(10) := '06:30 PM';
v_comp_begin_time DATE;
v_comp_end_time DATE;
v_days PLS_INTEGER := 0;
v_hrs NUMBER := 0;
v_ttltm NUMBER;
BEGIN
select trunc(v_end_date) - trunc(v_begin_date)
into v_days
from dual;
select to_date(to_char(sysdate,'DD-MM-YYYY')||' '||to_char(v_begin_date,'HH24:MI'),'DD-MM-YYYY HH24:MI')
into v_comp_begin_time
from dual;
select to_date(to_char(sysdate,'DD-MM-YYYY')||' '||to_char(v_end_date,'HH24:MI'),'DD-MM-YYYY HH24:MI')
into v_comp_end_time
from dual;
select (v_comp_end_time - v_comp_begin_time)/24 into v_hrs from dual;
IF v_hrs > 4 then
v_ttltm := v_days + .5;
ELSE
v_ttltm := v_days;
END IF;
return v_ttltm;
END;
As has been noted, this question is best posted on the PL/SQL forum.

hi,
try this.....
DateFormat formatter = new SimpleDateFormat("E MMM dd HH:mm:ss Z yyyy");
Date date = (Date)formatter.parse(dateStr); //// dateStr <- from date value (that is string value)
Date dateto = (Date)formatter.parse(datetostr); //// datetostr <- to date value (to date getting from as a string)
Calendar cal = Calendar.getInstance();
cal.setTime(date);
Calendar calto = Calendar.getInstance();
calto.setTime(dateto);
fromDate = cal.get(Calendar.DATE) + "/" + (cal.get(Calendar.MONTH) + 1) + "/" + cal.get(Calendar.YEAR);
toDate = calto.get(Calendar.DATE) + "/" + (calto.get(Calendar.MONTH) + 1) + "/" + calto.get(Calendar.YEAR);
// System.out.println("from Date : " + fromDate);

Hi
To break the diff between 2 dates into days, hours, minutes, sec -- you can use the following:
select to_char( created, 'dd-mon-yyyy hh24:mi:ss' ),
trunc( sysdate-created ) "Dy",
trunc( mod( (sysdate-created)*24, 24 ) ) "Hr",
trunc( mod( (sysdate-created)*24*60, 60 ) ) "Mi",
trunc( mod( (sysdate-created)*24*60*60, 60 ) ) "Sec",
to_char( sysdate, 'dd-mon-yyyy hh24:mi:ss' ),
sysdate-created "Tdy",
(sysdate-created)*24 "Thr",
(sysdate-created)*24*60 "Tmi",
(sysdate-created)*24*60*60 "Tsec"

Calculate the Difference Between two dates excluding weekends and Holidays

Hi,
We need to calculate the difference between the two dates by excluding the Local public holidays (It is global and varies across countries) and weekends should not be included in calculation for a business day in OBIEE.
We have two dates: Open date and close date when ever close date is null we are calculating age based on taking the current timestamp and need to exclude the weekends and Holidays when ever the close date is null.
Ex:
Col1 col2 Total
11/9/2010 2:46:38 PM Null 13
11/2/2010 8:06:26 PM 11/3/2010 5:37:03 PM 1
(In the Total we shouldn't include the weekends,holidays)
Please let me know how to calculate the difference between two dates by excluding the weekends and holidays.
Thanks

I wanted to know how do you calculate the number of days between two dates

i wanted to know how do you calculate the number of days between two dates in java ? i get both the dates from the database. i guess there are many issues like leap year and Febuary having diff no of months ..etc.

thanks..
I solve my problem as
public class MyExample {
    public static void main(String a[]) {
        String stdate = "2009-03-01";
        java.sql.Date currentDate = new java.sql.Date(System.currentTimeMillis());
        java.sql.Date preDate = java.sql.Date.valueOf(stdate);
        System.out.println(currentDate);
        System.out.println(preDate);
//        int dateCom = preDate.compareTo(currentDate);
//        System.out.println(dateCom);
        long diff = currentDate.getTime() - preDate.getTime();
        int days = (int) Math.floor(diff / (24 * 60 * 60 * 1000));
         System.out.println(days);

Calculate difference between two dates/times

Hi all,
Is there any function module to calculate difference between two dates/times which are in TIMESTAMPL format.
I need to know how many millisconde(second,minutes, hours... )there is between these two times.
Please, It is urgent
Thank you all.
Karim

hi,
try the following function
CALL FUNCTION 'CCU_TIMESTAMP_DIFFERENCE'
      EXPORTING
           timestamp1 = timestamp1
           timestamp2 = timestamp2
      IMPORTING
           difference = diff
      EXCEPTIONS
           OTHERS     = 1.
the above function gives the difference in seconds...
try the following code to set the resolution to milliseconds..
SET RUN TIME CLOCK RESOLUTION LOW
check the thread for details:
SET RUN TIME CLOCK RESOLUTION?
all the best!!!

Calculate the difference between two dates

I would like to calculate the difference between two dates in PL/SQL and return the result as a number of days expressed as an integer value.

Denes,
A fair point, I should really have posted this on the SQL forum (I'm new to the forum as well as PL/SQL) but thanks for responding anyway. It does raise a question as to how to implement this in ApEx though.
I have created the function and am calling it as shown below from the source window of a form. The source type is 'PL/SQL expression or function' and the expression in the source window of the form is:
calc_date_difference (:p26_c_payment, :p26_c_rec)
The two parameters being passed are of type date but I'm not sure how to handle the ruturned number and populate the form in ApEx with this value.
Is it possible to do it this way or am I taking completely the wrong approach?
Regards
Sandy
This is not ApEx related but SQL related:
CREATE OR REPLACE FUNCTION calc_date_difference (
p_date_1   VARCHAR2,
p_date_2   VARCHAR2
RETURN NUMBER
v_difference   NUMBER;
v_sql_err      VARCHAR2 (4000);
BEGIN
v_difference := TRUNC (TO_DATE (p_date_1)) - TRUNC
(TO_DATE (p_date_2));
RETURN v_difference;
CEPTION
WHEN OTHERS
THEN
v_sql_err := SQLERRM || CHR (10) || CHR (10) ||
SQLCODE;
ND calc_date_difference;and
