How do you find the difference in no. of days between 2 dates?

How do you find the difference in no. of days between 2 dates ?

There are 2 way to solve this: using java.util.GregorianCalendar or java.util.Date (like jesper1 suggested), depending what kind of solution You need:
        GregorianCalendar gc1 = new GregorianCalendar(2001, 01, 01, 23, 00, 00);
        GregorianCalendar gc2 = new GregorianCalendar(2001, 01, 03, 10, 00, 00);
        // 1st way using GregorianCalendar
        int diff1 = gc1.get(GregorianCalendar.DATE) - gc2.get(GregorianCalendar.DATE);
        System.out.println("Differnce: " + diff1);
        // 2nd way using Date
        int diff2 = (int)(gc1.getTime().getTime() - gc2.getTime().getTime()) / (24 * 60 * 60 * 1000);
        System.out.println("Differnce: " + diff2);Note: There are 2 days between the given dates, but exactly 1 day and 11 hours.
The first solution returns "-2", the second returns "-1".
(... and a 4th posting also won't help ...)

I am trying to check the last date (i.e. max date) and also check the penultimate date (i.e. the second to the last date). And then find the difference between the two (i.e. last date minus penultimate
date).
I would like to do that for each of the companies listed in Table 2: Tickers. I am able to do it for just one company (MSFT) using the queries below:
SELECT
[First] = MIN(ExDate),
[Last] = MAX(ExDate),
[Diff] = DATEDIFF(DAY, MIN(ExDate), MAX(ExDate))
FROM (
SELECT TOP 2 Dividends.ExDate
FROM Dividends, Tickers
WHERE Dividends.symId=Tickers.symId
AND Tickers.Symbol='MSFT'
ORDER BY ExDate DESC
) AS X
Outputs the following result:
First
Last
Diff
2012-11-13
2013-02-19
98
But what I would like instead is to be able to output something like this:
Symbol
First
Last
Diff
MSFT
2012-11-13
2013-02-19
98
AAN
2012-11-13
2012-12-14
1
X
2012-11-13
2012-12-14

Can anyone please let me know what do I need to add on my query in order to achieve the desired output?
Any help would be greatly appreciated.
Thanks in advance.

Could you try this?
create table Ticker (SymbolId int identity primary key, Symbol varchar(4))
insert into Ticker (Symbol) values ('MSFT'), ('ORCL'), ('GOOG')
create table Dividend (DividendId int identity, SymbolId int constraint FK_Dividend foreign key references Ticker(SymbolId), ExDate datetime, Amount decimal(18,4))

I want to find the difference(duration) between logon and logoff time?

i want to find the difference(duration) between logon and logoff time of below table?
can any one tell the query to find using self join?

No selfjoin, just analytical functions.
CREATE TABLe log_time
(username varchar(20),
LOGON_TIME timestamp,
LOGOFF_TIME timestamp);
insert into log_time (username,LOGON_TIME,LOGOFF_TIME) values ('HR',sysdate,null);

insert into log_time (username,LOGON_TIME,LOGOFF_TIME) values ('HR',sysdate+2,null);
insert into log_time (username,LOGON_TIME,LOGOFF_TIME) values ('HR',null,sysdate+2+14/20);
commit;

               LEAD(logoff_time,1,logon_time) OVER (PARTITION BY username ORDER BY time_to_sort) my_logoff_time,
               time_to_sort
        FROM (SELECT username,logon_time,logoff_time,NVL(logon_time,logoff_time) time_to_sort
              FROM log_time)
where LOGON_TIME is not null
ORDER BY time_to_sort;
USERNAME     LOGON_TIME     LOGOFF_TIME     MY_LOGOFF_TIME     MY_LOGOFF_TIME-LOGON_TIME     TIME_TO_SORT
HR     02.11.10 11:34:56.000000000          02.11.10 12:12:50.000000000     0 0:37:54.0     02.11.10 11:34:56.000000000
HR     04.11.10 11:34:56.000000000          05.11.10 04:22:56.000000000     0 16:48:0.0     04.11.10 11:34:56.000000000But, if that code which fills that table should better UPDATE than INSERT. You can cover much more issues. (e.g the DB crashes and you get 2 logon but no logoff in a sequence and.....)

An anyone help me to find the difference and relation between the following

Hi,
can anyone help me to find the difference and relation between the following methods of Swing :
a) validate()
b) invalidate()
c) revalidate()
d) repaint()

You'd be far ahead by opening up the API and Java turorial and your course book and learning for yourself, rather than, asking other to do your homework for you.
But if you have andwers already to go, then post them and ask if you have drawn appropriate conclusions.

Find the difference between loading and registering the drivers..

Dear Sir..
Could you please help me to find the difference between two activities..
1.Loading the drivers
2.Registering the drivers
What's the difference between loading and registeing the drivers and what activities take place by the JVM to do it all.

Dear Sir..
Could you please help me to find the difference
between two activities..
1.Loading the drivers
2.Registering the drivers
What's the difference between loading and registeing
the drivers and what activities take place by the JVM
to do it all.You load a class - it isn't specific to a driver.
That is part of java - not JDBC.
Normally JDBC drivers register themselves when the class is loaded. This is specific to the driver and has nothing to do with a user of the driver. It is only a concern to someone who must implement a driver.

Hi,
goto table COSP:
1) object-no. beginning with 'KS' refer to cost-centre
   example: 'KSKOKA4711'
   with KS, KOKA = controlling area and 4711 = cost centre
2) OBJNR beginning with 'PR' refer to projects / WBS-element

Extract Time from date and Time and Need XLMOD Funtion to find the Difference between Two Time.

X6 = "1/5/15 5:16 AM" & NOW ....................difference by Only Time
not date
X6 date and Time will be changing, Its not Constant
Dim myDateTime As DateTime = X6
            Dim myDate As String = myDateTime.ToString("dd/MM/yy")
            Dim myTime As String = myDateTime.ToString("hh:mm tt")
            Dim myDateTime1 As DateTime = Now
            Dim myDate1 As String = myDateTime1.ToString("dd/MM/yy")
            Dim myTime1 As String = myDateTime1.ToString("hh:mm tt")
Need to use this function to find the Difference between Two Time. due to 12:00 AM isuue
Function XLMod(a, b)
    ' This replicates the Excel MOD function
    XLMod = a - b * Int(a / b)
End Function
Output Required
dim dd = XLMod(myTime - myTime1)
Problem is myTime & myTime1 is String Need to convert them into Time, Later use XLMOD Funtion.

Induhar,
As an addendum to this, I thought I'd add this in also: If you have two valid DateTime objects you might consider using a class which I put together a few years ago
shown on a page of my website here.
To use it, just instantiate with two DateTime objects (order doesn't matter, it'll figure it out) and you'll then have access to the public properties. For this example, I'm just showing the .ToString method:
Option Strict On
Option Explicit On
Option Infer Off
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles MyBase.Load
Dim date1 As DateTime = Now
Dim date2 As DateTime = #1/1/1970 2:35:00 PM#
Dim howOld As New Age(date1, date2)
MessageBox.Show(howOld.ToString, "Age")
Stop
End Sub
End Class
I hope that helps, if not now then maybe at some point in the future. :)
Still lost in code, just at a little higher level.
Thanx frank, can use this in Future....

Function Module to find the Difference between two times.

Hi All,
Wud you plz let me know the Function Module to find the Difference between two times.
Input Time1( Hours:Minutes) Time2 ( Hours:Minutes)
Need Output in Hours:Minutes only . ( No seconds Needed )
Ex :
Input :
       06:00 to 18:00 Output : 12:00
and 20:00 to 06:00 Output: 10:00 with +ve sign only. No -ve sign.
Thanks,
N.L.Narayana

check this .
data : p_timel like sy-uzeit,
       p_timeh like sy-uzeit,
       diff like sy-uzeit,
       di(8) type c .
       p_timel = '200000'.
       p_timeh = '060000'.
       diff = p_timeh - p_timel.
       concatenate diff+0(2) ':' diff+2(2) into di.
       write:/ di.
also check for this.
       p_timel = '060000'.
       p_timeh = '180000'.
see if this can be implemented in ur code .
or else u can try with Fm L_TO_TIME_DIFF passing startdate enddate starttime endtime with UOM as MIN
hope this helps regards,

BCT - how to find the difference between installed BCT and the newest BCT?

Hi,
How do I find the difference between installed BCT and the newest BCT?
or find a description of the newest BCT?
Thank you.

Hi,
Thank you for your answer.
I am aware of the possibilities you mention.
I am looking for a way to find the parts of the business content that has been modified since I installed our current version WITHOUT installing anything.
That is for example:
If F&R business content has been moved from 3.x technology to 7.0
If there is changes to the F&R content at all
-> if our current version of business content already contains the newest version of Business Content for F&R, then it is not a prerequirement to an F&R project that we update business content.
The possibility to see that the only changes might be in the area of SAP HCM ...
Thank you.
