Calculating the difference between 2 dates that ristrict 0CALDAY

Hello.
Is there an oppotunity to calculate the difference between 2 dates, that restrict the characteristic 0CALDAY.
If i make the formula with
1. type - replacement path
2. interval use - difference
than the difference could be calculated wrong(example 20070301 and 20070101 - result 201)
Is there another way do solve the problem?
Best regards,
Andrey

Hi,
as you said, you need to create 2 formula variables.Both of them should have Replacement path as the preocessing type. And then use a formula to do the difference above 2 formula varibles.
Now check these settings for both variables:
Replacement Path
Replace Variable with: Key
For Intervals Use: From Value
Currencies and Units
Dimension ID: Date
Then it should work

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

Calculate the difference between Creation date and key date

Hello
I want to calculate the difference between creation date of the document with key date(todays date). How can i do that in the query designer. Also then I want to restrict my key figure on this difference if it is =10..please can someone suggest what can be done
thanks

Hi Grame...
For the days calculation ..
I suggest you to use replacement path ..
I have the reference that you can see the sample. The case of samples is also about day calculation.

What is the difference between delivery date and actual goods issue date?

Hi ,
Can you please tell me the difference between Delivery date and Actual goods issue date ?
Delivery data can be be greater than goods issue date?
Thanks,

Hi Ajay,
Delivery date means its the original date on which the delivery should be done.Actual goods Issue date is the date on which goods to be delivered according to the purchase order.There can be delay in the delivery so we maintain 2 objects.
Yes delivery date can be greater than Goods Issue date.
Hope this clears

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..

Getting the difference between 2 dates

Hi,
I am creating a Date object (using today;s day, month and year. hours and minutes come from a config file) and getting the difference between this date and the current date and time.
My code is as follows:
I am passing 07:30 into the method as the parameter aSstart_time.
Calendar newCalendar = Calendar.getInstance(Locale.UK);
 SimpleDateFormat dtformat = new SimpleDateFormat("dd-MM-yy HH:mm");
 int lIYear = newCalendar.get(newCalendar.YEAR);
 int lIMonth = newCalendar.get(newCalendar.MONTH);
 int lIDay = newCalendar.get(newCalendar.DAY_OF_MONTH);
 String lSstartHrs = aSstart_time.substring(0,aSstart_time.indexOf(":"));
 //System.out.println(">>>>>>>>> THE HOURS IS: " + lSstartHrs);
 String lSstartMins = aSstart_time.substring(aSstart_time.indexOf(":")+1,aSstart_time.length());
 //System.out.println(">>>>>>>>> THE MINS IS: " + lSstartMins);
 java.util.Date ldStartTime = new java.util.Date(lIYear,lIMonth,lIDay, Integer.parseInt(lSstartHrs),Integer.parseInt(lSstartMins));
 System.out.println("Year: " + lIYear);
 System.out.println("Month: " + lIMonth);
 System.out.println("Day: " + lIDay);
 System.out.println("Hour: " + Integer.parseInt(lSstartHrs));
 System.out.println("Min: " + Integer.parseInt(lSstartMins));
 System.out.println("The number of milliseconds for current time is: " + newCalendar.getTime().getTime());
 System.out.println("The number of milliseconds for 07:30 is: " + ldStartTime.getTime());
 System.out.println("calendar time: " + dtformat.format(newCalendar.getTime()).toString());
 System.out.println("created time: " + dtformat.format(ldStartTime).toString());
 if(newCalendar.getTime().getTime() < ldStartTime.getTime()){
 System.out.println("The current time is less than the config time (07:30)");
 else{
 System.out.println("The time is greater than 07:30");
 }When I run this program at 10:06am I get the following output:
Year: 2006
Month: 1
Day: 15
Hour: 7
Min: 30
The number of milliseconds for current time is: 1139997962321
The number of milliseconds for 07:30 is: 61098132600000
calendar time: 15-02-06 10:06
created time: 15-02-06 07:30
The current time is less than the config time (07:30)
The Date.gettime() method should measure the number of milliseconds after 01-01-1970 so the number of milliseconds for the current time (10:06am) should be greater than the number of milliseconds for 07:30. A you can see in the above output this is not the case.
Anybody have any idea why this is happening. Am I using the .gettime() method for the correct purpose.
Any ideas or suggestions would be greatly appreciated.
Thanks

It is beacause Calendar use fully defined year as parameter, so Calendar.set(year + 1900, month, date, hrs, min) is (almost) equivalent to new Date(year, month, date, hrs, min)Example: int year = 85; // old way of specifying a year in a Date
 int month = 3;
 int date = 12;
 int hrs = 12;
 int min = 0;
 Calendar cal = Calendar.getInstance();
 cal.set(year + 1900, month, date, hrs, min);
 Date d = new Date(year, month, date, hrs, min);
 System.out.println(d);
 System.out.println(cal.getTime());You will obtain the same date (except seconds and miliseconds in this case, as they probably won't be zero with Calendar.getInstance(); )

hi,
try this.....

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);

What is the Difference Between Sys Date and Effective Date ??

Hi Gurus,
Can any one pls let me know What is the Difference Between Sys Date and Effective Date ??
with regards
User600722

EFFECTIVE DATE usually refers to a date-tracked record (although not exclusively).
Date-tracked records in Oracle HR have an EFFECTIVE START DATE and an EFFECTIVE END DATE. The record is 'EFFECTIVE' between these dates. In reports, you often use SYSDATE to compare to these two dates to find the CURRENT effective record, e.g. SYSDATE BETWEEN EFFECTIVE START DATE AND EFFECTIVE END DATE.
When you make changes to a HR record, you can choose between DATE TRACKING options, such as CORRECT or UPDATE (there are others too). CORRECT will overwrite the record and replace the data with your changes. This is normally used when you need to correct something that is wrong. UPDATE will create a new version of the record from the EFFECTIVE START DATE you choose. It will also set the EFFECTIVE END DATE of the previous record to the day before your new record's EFFECTIVE START DATE. That enables a history of records to be maintained so you can see what your data looked like at ay one point in time.

Tim

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
SQL> SELECT calc_date_difference ('23.01.2007',
'20.01.2007') diff

Facing problem while calculating the difference between the two dates?

Hi
I am using this code to calculate the difference between the two dates :
import java.util.Calendar;
import java.util.*;
public class DateDifferentExample
public static void main(String[] args)
// Creates two calendars instances
Calendar cal1 = Calendar.getInstance();
Calendar cal2 = Calendar.getInstance();
// Set the date for both of the calendar instance
cal1.set(2006, 12, 30);
cal2.set(2007, 05, 03);
// Get the represented date in milliseconds
long milis1 = cal1.getTimeInMillis(); // getting error here
long milis2 = cal2.getTimeInMillis(); // getting error here
// Calculate difference in milliseconds
long diff = milis2 - milis1;
// Calculate difference in seconds
long diffSeconds = diff / 1000;
// Calculate difference in minutes
long diffMinutes = diff / (60 * 1000);
// Calculate difference in hours
long diffHours = diff / (60 * 60 * 1000);
// Calculate difference in days
long diffDays = diff / (24 * 60 * 60 * 1000);
System.out.println("In milliseconds: " + diff + " milliseconds.");
System.out.println("In seconds: " + diffSeconds + " seconds.");
System.out.println("In minutes: " + diffMinutes + " minutes.");
System.out.println("In hours: " + diffHours + " hours.");
System.out.println("In days: " + diffDays + " days.");
but i am getting this error :
The method getTimeInMillis() from the type calendar is not visible
Please suggest!!

// Get the represented date in milliseconds
long milis1 = cal1.getTime().getTime(); // getting error here
long milis2 = cal2.getTime().getTime(); // getting error here Hope this works for you!!

The Difference between "Cell Data" and "Dimension Data"?

What is the difference between the tab "Cell Data" and "Dimension Data" in SSAS?

Article quote: " SSAS provides the way to secure analysis services database/cube data from unauthorized access. Analysis services provides secure access by creating object called "roles". After creation of role, user's windows login credential can be used
to enroll into particular role because analysis services identifies user from their windows login credentials . You can protect your data in roles at two levels:
1) Dimension level
2) Cell level
If user has been assigned more than one role, analysis services loop through all assigned roles after login. Analysis services finds all permission level for the particular user and union all the permission levels.
If two roles has contradictory access for user then particular access will be allowed. Suppose role1 says Australia data access and role2 denies Australia data access then access to Australia data will be allowed. "
