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.

     return parseFloat($x(item).value);
   else
     return 0;
    $x('P36_C').value =
getval((TO_DATE('P36_B', 'DD-MON-YYYY'))-

</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.

[Urgent] Need help calculating difference between two dates

I'm trying to write a code to display the current day and time, then accept two dates from the user and display the difference between the two dates. To display the current date and time, I've used the SimpleDateFormatter library but I'm having difficulty calculating the difference between two dates. Could someone please help me with this?
Below is my code so far
import java.util.Date;
import java.util.Scanner;
import java.text.SimpleDateFormat;
public class DateFormatter {
     public void displayNow()
          Date todaysDate = new Date();
          SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MMM-dd HH:mm:ss");
          String formattedDate = formatter.format(todaysDate);
          System.out.println("Today's date and time is: "+formattedDate);
     public void calculateDifference(Date startDate, Date endDate)
          /* This is whre i need help! */
     public static void main(String[] args)
          DateFormatter df = new DateFormatter();
          Scanner sc = new Scanner(System.in);
          df.displayNow();
          System.out.println("Please enter a date: ");
          String date1 = sc.next();
          System.out.println("Please enter another date: ");
          String date2 = sc.next();
}The methods displayNow() and calculateDifference(Date startDate, Date endDate) are essential and cannot be skipped out.

Of course, it takes some time to learn what the intelligent questions are. You have my sympathy. Try asking questions about how to do a particular task, instead of asking people to tell you what to do. It starts to get easier after a while.
actually dude i started on this on monday.. but there were so many other stuff to do along with this.. and i did try referring up the Calendar utility but it was a bit confusing actually.. it was only after that did i come to this forum.. nor am i very good at Java.. anyhoo thanks for your sympathies :P

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);

Difference between two date in bex query

Hi all,
I need to do a difference between two date using formula variable processing type customer exit beaucause I must use factory calendar in the formula.
How can I do it?
Can you give me an example of the routine?
Thanks a lot
Gianmarco

Hi,
You can still use the same code to copy it and customize as per your need. All you need to do is to subract the dates using the class: CL_ABAP_TSTMP after converting to timestamp and resulting seconds you convert back to days....Please get help from the developers to do this...
Also, ensure that you write back this difference value to your variable so you get it on the reports for your calculations...
Cheers,

Difference between two dates

Hi
I have two date fields in the ODS..Both are characterists
1. Requested delivery date
2. Actual shipment end date.
I would like to create a calculated KF field for the difference between two dates in a query.
How can I accomplish it?
Regards

You have to make Expiration data as nav attribute and create a formula variable then only this date can be used in calculations.
refer this How to...for the same
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/72f4a790-0201-0010-5b89-a42a32223ffc

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

To find difference between two dates

Hi all,
I am new to this forum and oracle.
I want to get the difference between two dates. My query is as below...
sqlserver_utilities.datediff('YY', startdate,enddate)
I want the difference in year.
Please help me. It's really urgent.
Thanks in advance.
Regards,
Inam

Select to_char(enddate,'YY') - to_char(startdate,'YY') fromPLEASE don't do that. There are so many things wrong with it...
for example:
1). Why are you subtracting character data types?
2). What if the start date is 1999 and the end date is 2000? Do you expect to get a difference of -1?
3). What if the start date is 1 Jan 2000 and the end date is 31 Dec 2000? Do you expect to get 0 instead of 1 or .997?
4). Why would you convert dates to something else when they are inherently subtractable.
5). There are obvious points in the OP's "specification" that are vague - the best thing (after telling them to search, of course since this has been answered a million times already) would be to try to clarify the spec.

As to the data type of the data type of the difference between two date type of datas

Hi,
I have a question about the data type of the difference between two date type of datas.
There are two date type of datas as:
SSHIPMENTS.RECEIVEDATETIME
SSHIPMENTS.PROMISEDATETIME
I try to use the following SQL Script in Oracle SQL*Plus as:
SELECT CASE
WHEN (SSHIPMENTS.RECEIVEDATETIME - SSHIPMENTS.PROMISEDATETIME) < '000 01:00:00.000' THEN 'OnTime'
WHEN (SSHIPMENTS.RECEIVEDATETIME - SSHIPMENTS.PROMISEDATETIME) < '000 01:30:00.000' THEN '60-89 Minutes'
ELSE '3+ Hours'
END
FROM SSHIPMENTS;
The error message of "Invalid Number" for the '000 01:30:00.000' happens.
I don't know if the data type of the interval is wrong.
Many Thanks,
Cathy

SELECT CASE
WHEN (to_char(SSHIPMENTS.RECEIVEDATETIME,'hhmiss') - to_char(SSHIPMENTS.PROMISEDATETIME,'hh24miss')) < '010000' THEN 'OnTime'
WHEN (to_char(SSHIPMENTS.RECEIVEDATETIME,'hhmiss') - to_char(SSHIPMENTS.PROMISEDATETIME,'hh24miss'))< '000 01:30:00.000' THEN '60-89 Minutes'
ELSE '3+ Hours'
END
FROM SSHIPMENTS;
just try it out..
