How to get the diff between two dates - # of days

Hi Experts,
I have requirement to know the difference between dates. In my presentation layer two columns as created date and updated date. I want to know the difference in # of days in the presentation services.
Please provide some pointers.
Thanks in adv
svr

Hi,
In the presentation layer you can create a column with a custom formula of this:
TIMESTAMPDIFF(SQL_TSI_DAY, datecolumn1,datecolumn2)
The result shown in the column will be the difference in days between the two dates.

Matt

How to get the difference between two dates???

HI I have two dates and I want to test if there is an hour between them.
Is there a way to compare two dates like mySQL can with dateDiff(date1,date2);
Thanks alot.

This link is now out of date as they have revamped the structure. Yep. Here it is again: http://forum.java.sun.com/thread.jsp?forum=31&thread=502686
I've also noticed that my comment regarding daylight saving was misleading. The demonstrated method for calculating difference between Dates is reliable. However, one needs to be careful when interpreting Dates in a daylight saving timezone.

How to get the difference between two HashMaps

How to get the difference between one and two and put the result in the third

My bad, difference of course means removeAll():Map<Integer,Object> first = new HashMap<Integer,Object>();

third.keySet().removeAll(second.keySet());No loops needed.

How to get the difference between two columns in a column group

Hi All,
My first time here and really new to programming. I would like to get the difference between 2 columns that are inside
a column group.
Here is my sample table below: The Column Group is PeriodNumber and can only choose 2. like 1 and 2.. I would like to have a third row which will simply calculate the difference between the amounts in PeriodNumber 1 and 2.
PeriodNumber
Account 1 2
1) Cash 10,000 15,000
2) Receivables 12,000 11,500
3) Equipment 5,000 5,500
Total Assets 27,000 32,000

Hi yabgestopa,
From your description, you want to get the difference between two columns in a column group. After testing it in my environment, we can use custom code to achieve your requirement. For more details, you can refer to the following steps:
Copy the custom code below and paste it to your report. (Right-click report>Report Properties>Code)
Dim Shared Num1 As Integer
Dim shared Num2 As Integer
Public Function GetAmount(Amount as Integer, Type as String)
If Type = "1" Then
Num1=Amount
Else
Num2=Amount
End If
Return Amount
End Function
Public Function GetDif()
Return Num1-Num2
End function
Right-click the second column to insert a third column with Outside Group-Right.
Then use the expressions below in the matrix.
=Code.GetAmount(Fields!Amount.Value,Fields!PeriodNumber.Value)
=code.GetAmount(Sum(Fields!Amount.Value),Fields!PeriodNumber.Value)
=Code.GetDif()
The report looks like below.
If you have any questions, please feel free to ask.
Thanks,

How to get the difference of two dates?

let's say i have a table named tblData and has 4 columns: data_RefNo, data_DateReported, data_TargetDate, data_Data
tblData returns 2 rows.
data_RefNo.............data_DateReported.............data_TargetDate........................data_Data
10000................10-20-2004 10:55:44 AM........10-20-2004 10:57:44 AM........Slow Response Time
10000................10-21-2004 10:55:44 AM........10-21-2004 11:55:44 AM........Bug Error
i just wana ask how to get the difference of the date_DateReported and date_TargetDate.
i tried this code but it didnot work
public Vector get_con_pf()
Vector vData = new Vector();
String query = "SELECT * FROM tblData WHERE data_RefNo= '"'10000'"'";
try
    DBConnect db = new DBConnect();
    db.openCon();
    ResultSet rs = db.execute(query);
    while (rs.next())
      vData.addElement(DATEDIFF(mi, rs.getString("st_DateReported"), rs.getString("st_TargetFinishDate")));
    db.closeCon();
catch (Exception e)
    System.out.println("Error: " + e );
return vData;
i want to return the difference of the data_DateReported and date_TargetDate, i did this
vData.addElement(DATEDIFF(mi, rs.getString("st_DateReported"), rs.getString("st_TargetFinishDate")));but it didnot work.
How do i get that? because i want to return a vector.
the code must return the values:
2 for the 1st rows because the difference is only 2 minutes, and
60 for the 2nd row.

ooops i tried this one:
query = "SELECT *, DATEDIFF(mi, data_DateReported, data_TargetDate) AS diff FROM tblData WHERE data_RefNo = '10000'";and it works.
hehehehe!!!!!!
problem solved! :)

How to find the difference between two date?

Hi,
I currently writing a date comparision program. Below is the idea analogy,
Currently i need to find how many day differences between 30 July 2003 and 22 June 2004. How can i use java to code it?
Thanks.

there doesn't seem to be a direct way but try this:int daysBetween = 0;
Calendar c = new GregorianCalendar(2004, Calendar.JULY, 30);
Calendar d = new GregorianCalendar(2003, Calendar.JUNE, 22);
while (c.get(Calendar.YEAR) != d.get(Calendar.YEAR)) {
daysBetween += 360;
d.add(Calendar.DAY_OF_YEAR, 360);
daysBetween += c.get(Calendar.DAY_OF_YEAR) - d.get(Calendar.DAY_OF_YEAR);This gives the correct result of 404 (= 8 days from June 22 to June 30 + 366 days between July 1 of 2003 and 2004 + 30 days from July 1 to July 30)

How to get the 'link' between two tables

hi pple
i need to find out HOW two tables are related.
sample tables:
SHIPS ( HULL_ID [PK] , VESSEL_NAME, GROSS_TONNAGE )
EQUIPMENT ( E_ID [PK] , HULL_ID [FK frm SHIPS], DESC )
PARTS ( PART_ID [PK] , E_ID [PK, FK frm EQUIPMENT], MANUFACTURER_ID)
--> SHIPS and PARTS are some how related thro' EQUIPMENT.
i need to get this relationship:
Ships --> Equipment (E_ID) --> PARTS
currently, i can get the direct parent and child tables of a given table using:
SELECT lpad ( ' ', 2 * ( LEVEL - 1 ) ) || table_name as Child_Tables
FROM ALL_CONSTRAINTS
START WITH R_CONSTRAINT_NAME in
select constraint_name
from all_constraints
where table_name = '%table_name%'
and constraint_type = 'P'
CONNECT BY PRIOR CONSTRAINT_NAME = R_CONSTRAINT_NAME ;
To get ALL parents:
SELECT lpad ( ' ', 2 * ( LEVEL - 1 ) ) || table_name as Parent_Tables
FROM ALL_CONSTRAINTS
where owner = 'CHARTUSER'
START WITH CONSTRAINT_NAME in
select constraint_name
from all_constraints
where table_name = '%table_name%'
and constraint_type = 'R'
CONNECT BY PRIOR R_CONSTRAINT_NAME = CONSTRAINT_NAME ;
what i need to do is:
1) get children & parents of SHIPS
2) for each element of (1), get children, parents till i get PARTS
3) so, i will get EQUIPMENT and then, PARTS.
this wud be very expensive. my appln is in Java and i will need to call these functions - that makes it more complex. is there any simpler way out?
and my main problem is to find out WHAT attributes line two tables. this wudnt be a big deal if it were just simple parent-child tables. but, how do i find out the attributes that link PARTS and SHIPS table?
any ideas? -please help.
thanks in advance

Dear Srikanth,
This tables can be used once we come to know whether its a customer or vendor line item but in our case we using the GL account as reference have to knock off the entries.How we come to know that aginst the GL whether its a customer or vendor line item.. Then it should route to this table.
Suggest me if any options are there.

How to calculate the difference between two dates?

Hello,
I would like to write some code which figures out how many days are between the Date_of_change (which is of datatype DATE, length 7 and of format DD-MON-YY) and the current date today. Then if the difference between Date_of_change and the current date is greater that 30 days for example then I would like to delete that record from the database.
Thanks

i only want to get the different part of two continuous BufferedImages and send ti over internet.
I have compared two BufferedImages by RGB (int[]), but this process wastes 400~500ms,it's terrible,:)
who has any good idea about this?
thanks

thanks ! cary ,
I have a list contained some BufferedImages gotten from AWT component,and then these images
will be transfered to client and displayed in Internet explore ,actually there are only some difference
between two continuous BufferedImages,i don't want to transfer the WHOLE image to client,SO i
want to handler every image before sending to client , at last, the different part will only be sent to client.
All these ideas will be contained this method:
* Compare the specified two BufferedImages and return the different part between them.
* @param ref the specified first image
* @param gen the specified sencond image
* @return the different part between the specified two images.
public static void BufferedImage compareBufferedImage(BufferedImage ref,BufferedImage gen){
to finish this method ,do you have any good ideas?or sample code?
