Erm... that only works if the minutes are in the same hour, otherwise it's not giving the difference in minutes for the time part of the date...

Oracle Date Substraction

Hi all,
I have a question regarding Date substraction. I've read somewhere that the standard unit of Date Substraction of Oracle is days. However my requirements is to have result format in hours. Example:
Date1: 1/21/2010 08:00:00 AM
Date2: 1/22/2010 10:00:00 AM
Date2 - Date1 = 1 (day). If I need to convert to hours, I can achieve by multiply it by 24. But in fact the result for this should be 26 hours.
1 more example for this:
Date1: 1/21/2010 08:00:00 AM
Date2: 1/21/2010 10:00:00 AM
Date2 - Date1 - 0 (day). While in fact it should be 2 hours.
In short, I want Date substraction to give me result in hours rather than days. Is there anyway to achieve this objective using pure SQL in Oracle? or do I have to manipulate using some kind of programming language?
I've received a reply from the other thread saying that I could get the number of hours by mulitply the number of days by 24. This is true only if Oracle stores data in format like: 1.2 days after substraction. Is this the case with Oracle?
Thank you very much.
Thanh.

Date Substract Format

I'm trying to format following query.
SELECT TO_CHAR(START_DATE, 'HH:MM:SS'), TO_CHAR(END_DATE, 'HH:MM:SS'),
TO_CHAR(END_DATE - START_DATE, 'HH:MM:SS')
FROM TIMES
Oracle returns following message:
ORA-01481: invalid number format model
Somebody knows how to convert from number to date values?
I appreciate some help
Best regards

The problem is that when you subtract two dates, Oracle returns a number -- which is the 'portion of the day' -- you can take the result and multiply it by 86400 to get the number of seconds in a day and then convert that back to a date... Once this is converted back to a date - you can then convert it to a character - with your date format... Sounds kind of sloppy - and it is, but it works..
here's the example i used (which is REALLY SLOPPY)
SELECT TO_CHAR(TO_DATE(((SYSDATE - TO_DATE('28-JUN-2002 08:00','DD-MON-YY HH24:MI')) * 86400), 'SSSSS'), 'HH:MI:SS') FROM DUAL
Now, I'll attempt yours without testing..
SELECT TO_CHAR(START_DATE, 'HH:MM:SS'), TO_CHAR(END_DATE, 'HH:MM:SS'),
TO_CHAR(TO_DATE(((END_DATE - START_DATE, 'HH:MM:SS') * 86400), 'SSSSS'), 'HH:MI:SS')
FROM TIMES
Hope this helps!

How to add minutes to date in java

I have date in string variable, i have to add/subtract minutes from it, please adivce , how i could do in java 1.5
sample data
String olddate = "12/16/2010 4:58:29 PM"
String minutes1 = "300"
i would like to get value as below for above data
String newdate ="12/16/2010 9:58:29 PM"

Use SimpleDateFormat to convert the date object to string. Once the string object converted to date object use the getTime() method to get the date in milliseconds.
Now you can easily adds/substract the date object.
Remember, the resulting long value from getTime() method is in milliseconds, to get the value in minutes you need to multiply it by 1000 and by seconds in a minutes, that is 60.
When your subtraction/adds done convert it back to date object.
This is the codes:
import java.text.SimpleDateFormat;
import java.text.ParseException;
import java.util.Date;
public class DateCalculator {
     public static void main(String[] args) throws ParseException {
          String olddate = "12/16/2010 4:58:29 PM";
          System.out.println("old Date: "+olddate);
          SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy h:mm:ss a");
          long oldDateInMillis = formatter.parse(olddate).getTime();
          String minutes1 = "300";
          String newDateAdds = formatter.format(new Date(oldDateInMillis + Long.valueOf(minutes1)*1000*60 ));
          String newDateSubstract = formatter.format(new Date(oldDateInMillis - Long.valueOf(minutes1)*1000*60 ));
          System.out.println("new Date [Additions] : "+newDateAdds);
          System.out.println("new Date [Substraction] : "+newDateSubstract);
}

Fields For Good Reciept and Issed !

Hi all,
I want the fields for the goods reciept and good issued for getting the stock for a particular material as on to date (which is my selection screen) ...
I have selected the sales data from the VBRK and VBRP tables which is for sales information and now i need to find out the Stock information. My Requirement is to maintain sales stock and to show the Turn Over Ratio ???
Can you tell me the tables and the fields where i will get them ...
I m calculating my Stock as:
Stock (as on date) = Substracted Value (Reciepts - issues ) - current stock.

In MSEG there is field for Sales order number as well as item number from that you can get the Goods issues quantity,similarly in MSEG you also have purchase order number and purchase order item numner from which you can get the goods purchased quantity by passing it to VBAP and EKPO respectively.

Substract one day to a date in a XSLT mapping

Hi,
I need to map a ENDDA field to a new field but subtracting a day, and reformatting the date, e.g
from:
<ENDDA>20090213</ENDDA>
I need:
<ENDDA>12.02.2009</ENDDA>
For reformatting, sub string and concat with . is working, but how can I substract a day, including the handling where the date is the first day of the month?
thx for your inputs

I think this will help you.
Create one UDF and insert 2 parameters.
First parameter as your date
second is number of hours 24:00:00
Code:
   //write your code here
SimpleDateFormat sd = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
SimpleDateFormat sdTarget = new SimpleDateFormat("MM/dd/yyyy");
try {
Date currentDate = sd.parse(a);
Date compareDate = sd.parse(a.substring(0,10) + " " + b);
if (currentDate.after(compareDate) )
    Calendar c = Calendar.getInstance();
c.setTime(sdTarget.parse(a));
c.add(Calendar.DATE,1);
a = sdTarget.format(c.getTime());
else
//a = "before"
a = a.substring(0,10) ;
catch(Exception e)
return a;
This might need little modification as your need.
After that use Date Transformation function which will convert date in your required format.
Thanks,
Hetal

Substract days to a date

Does somebody know a method to substract to a given date (in String format dd/mm/yyyy) a given number of days??
public String restarDias(String fecha, int dias) throws Exception {
DateFormat df = DateFormat.getDateInstance();
Date fechaD = df.parse(fecha);
return dateResult;
}.. thanks!

Hi,
you can do this easily when you define a Calendar and then apply the method:
//somewhere in code
//Calendar Cal = Calendar.getInstance();
Cal.add(Calendar.DATE,3); //to add 3 days
Cal.add(Calendar.DATE,-1);//to substract one day

How to substract two date&time values

Well,i just need to substract last visited date&time value from systemdate. The last visited date&time(from the filed named SONBULUNMAZAMANI, ) is selected from table (IHALE_KATILIMCILAR ) in the format DD-MM-RRRR HH24:MI and systemdate is in the same format. And i need to get value in minutes. Then i need to check if the value is greater then 20 minutes, finally i will update database and set IHALE_KATILIMCILAR.AKTIF=0. Here is the code i used;
DECLARE
MinDiff number;
DateTime1 ihale_katilimcilar.sonbulunmazamani%TYPE;
BEGIN
select t.sonbulunmazamani into DateTime1 from ihale_katilimcilar t where t.ihlkodu=141 and t.ihlaltktgkodu=132 and t.id_iliski=193;
MinDiff := ABS( TO_DATE( TO_CHAR(SYSDATE, 'DD-MM-RRRR') || TO_CHAR(SYSDATE , 'HH24:MI'), 'DD-MM-RRRR HH24:MI' ) - TO_DATE( TO_CHAR(DateTime1, 'DD-MM-RRRR') || TO_CHAR(DateTime1, 'HH24:MI'), 'DD-MM-RRRR HH24:MI' ) );
DBMS_OUTPUT.PUT_LINE('Difference is ' || MinDiff);
END;
However the result i get is always pointed values such as ,1895833333333333333333333333333333333333. How can i handle this?
And here is the scripts of table:

What version of SQLServer do you have? Datediff is not an Oracle built-in function.
OP:
THe difference between two dates in Oracle is in days. The decimal portion refers to partial days, so you need to convert that to the required precision. Also, both sysdate and your column are date type, and contain a time portion, so you do not need all the to_date/to_char stuff. Something like:
SQL> SELECT end_dt, start_dt, (end_dt - start_dt) * 24*60 diff
2 FROM (SELECT sysdate end_dt, TRUNC(sysdate) start_dt
3        FROM dual);
END_DT             START_DT                 DIFF

Function to get the date after substraction

Hi Gurus,
I understand that the function "RE_ADD_MONTH_TO_DATE" is used for calculate the date after added certain month(s).
But, how do I do it in the other way. What I mean here is I want to substract the date.
For example my current date is 09.05.2008, substract 3 years is 09.05.2005.
All ideas and suggestion are greatly appreciated.
Thanks.

Hi ,
u can use the same function module RE_ADD_MONTH_TO_DATE with passing months in negetive number like,
month = -36.
in the function module.

kk.

Regarding substracting dates

Can we Substract 2 dates in the format 'WW-YYYY'
to get number of weeks??

Well your criteria aren't dates, they are just strings, so you need to extract the relevant parts and put those into the SQL... e.g.
SQL> ed
Wrote file afiedt.buf
1 WITH mydates as (select '51-2008' as end_date, '24-2008' as start_date from dual)
2 -- END OF TEST DATA

4        - (to_date('01-01-'||substr(start_date,4),'DD-MM-YYYY')+(to_number(substr(start_date,1,2))*7))

Substract date from date?

hello,
i try to substract a date from sysdate and format it like 'HH24:MI:SS'.
SELECT ID
, to_char (DLC,'DD.MM.YY HH24:MI:SS') as DateLastChange
, to_char (sysdate,'DD.MM.YY HH24:MI:SS') as ToDay
, to_char ((to_date(SYSDATE,'DD.MM.YY HH24:MI:SS') - to_date (DLC ,'DD.MM.YY HH24:MI:SS'))) as Time
FROM TEST_TABLE

thank's for help

Hi Rainer,
if you are using Oracle9i, you can use Day to Second Interval.
SELECT sysdate, hiredate ,NUMTODSINTERVAL( TO_CHAR( sysdate - hiredate ), 'day' ) from emp;
It gives you even the fractional millisecond difference upto a precision of 9.
SQL> insert into emp(empno,hiredate) values( 100, sysdate-1);
SQL> select NUMTODSINTERVAL(to_char(sysdate-hiredate),'day') from emp where empno=100;
NUMTODSINTERVAL(TO_CHAR(SYSDATE-HIREDATE),'DAY')
+000000001 00:03:13.000000000

SUBSTRACTING 2 DATES TO GET THE DIFFERENCE IN MINUTES

Hi
I want to substract 2 dates and to get the difference in minutes. Can you help me with that ?
Thanks

select (sysdate - (sysdate - 10)) * 24 * 60 from dual
where
sysdate - date1
(sysdate -10) - date2
24 - number of hours per day
60 - number of minutes per hour
Is this what you need?

Check out the Calendar class.Hello Kayaman,
From a quick glance at its API, I haven't found it obvious that Calendar could fulfill such need under 10-lines algorithms. As per Joda-time's proponents, it's one of those computation that are unintuitively hard or convoluted using the stock JDK date&time classes.
If you're comfortable with Calendar, maybe you'd find it interesting to voice your opinion in this other topic: {thread:id=1982257}. Thanks in advance.
Hello OP,
apologies for plugging that discussion in your topic. But I do think it's closely related.
I noticed you marked both replies as helpful. I'd like to know your feedback on those replies: have you tried both approaches, and succeed with one, or both? Have you met difficulties with either?
Thanks, and good luck anyway.

Substract 3 monts to a date in oracle bi publisher 11g

Hey forum
I need to create a sql query data set that groups my info by fiscal year.
what I'm having on my data set sql query editor right now is something like
select YEAR ("Credit Memo"."Cm Fecha Creacion") as yearGroup
from .................
and I'm using this field for my grouping.
the problem is that my fiscal years go from apr to apr.
so i would need something like select YEAR ("Credit Memo"."Cm Fecha Creacion" - 3 monts) as yearGroup
this will pull those rows from jan,feb and march to the last year. for example YEAR(02/02/2011 - 3 monts) = 2010
I've tried things like YEAR ("Credit Memo"."Cm Fecha Creacion" - "Credit Memo"."Cm Fecha Creacion") but it happens
that i cannot subtract from a date on the sql publisher editor.
I've spent several hours browsing and googling without any sucess :(
I can't even find a list of date functions (like the "YEAR" function i'm using) for publisher sql editor. This would help a lot because maybe I can figure out some sort of alternative solution.
Any help will be SUPER welcomed
Thanks!

Thanks so much for your help!
I've used add_months against oracle databases without any problem
Sadly this publisher sql editor is not taking the same functions as a regular sql + command line :(
Do you have any other idea?
Thanks!
