(Groovy Expression) Get the no. of days between two dates
Hi All,
I am using ADF-BC-11g to create an entity object with 2 specific columns ActualDate and EstimatedDate both of Date type. I also want an additional field DaysBetweenTwoDates showing the difference between these two dates. Hence, I add another attribute DaysBetweenTwoDates in my entity object and after removing the Persistent property, I modify the expression field as ActualDate - EstimatedDate. When I test my AM, I get an error as below:
*(oracle.jbo.JboException) JBO-29000: Unexpected exception caught: groovy.lang.MissingMethodException, msg=No signature of method: java.sql.Date.minus() is applicable for argument types: (java.sql.Date) values: {2009-04-01}*
Can anyone please tell me how to achieve the same?
Please note that I can not add a new column DaysBetweenTwoDates in the table nor can I have a new VO attribute subtracting and storing the difference as there are some logical and refreshing constraints.
Any suggestions would be really helpful.
Thanks
Neeraj
Thanks John,
Oops...I did not think on this ground at all. Thanks for directing towards right direction. However, just to know, is that possible anyways thorugh groovy expression? Do we have any docs where we can search for the functions available in groovy expression?

Neeraj

I wanted to know how do you calculate the number of days between two dates
i wanted to know how do you calculate the number of days between two dates in java ? i get both the dates from the database. i guess there are many issues like leap year and Febuary having diff no of months ..etc.
thanks..
I solve my problem as
public class MyExample {
public static void main(String a[]) {
String stdate = "2009-03-01";
java.sql.Date currentDate = new java.sql.Date(System.currentTimeMillis());
java.sql.Date preDate = java.sql.Date.valueOf(stdate);
System.out.println(currentDate);
System.out.println(preDate);
// int dateCom = preDate.compareTo(currentDate);
// System.out.println(dateCom);
long diff = currentDate.getTime() - preDate.getTime();
int days = (int) Math.floor(diff / (24 * 60 * 60 * 1000));
System.out.println(days);

SQL to count the number of days between two dates
Does any one have or know how to count the number of days/weeks between 2 dates.
I have thought about using MONTHS_BETWEEN, but do not know how to make it accurate down to one day?
Any suggestions would be appreciated.here are the different queries I came up with to do this, you may want to check it for perticular cases involving Sun and Sat as start and end dates.
select to_number(to_char(to_date('21-JUL-00','dd-mon-yy'), 'ww'))
- to_number(to_char(to_date('10-JUL-00','dd-mon-yy'), 'ww')) from dual;
select (Next_Day(to_date('21-JUL-00','dd-mon-yy')-1, 'Sunday')
- Next_Day(to_date('10-JUL-00','dd-mon-yy')-1, 'Sunday'))/7 from dual;
select (Next_Day(to_date('21-JUL-00','dd-mon-yy')-6, 'Sunday')

How can I calculate the maximum number of days between two dates in a range of dates?
I have a column of dates spanning the couse of a few months. I would like to know if I can calculate the maximum number of days between each row and display the highest number. I currently have another column that calculates the days betwen the rows and I am currently just looking at the totals and highlighting the highest period.
Is this possible? Any help or suggestions are appreciated.
Thank you,
TrevorThis sounds totally possible, Can you post a screen shot of your table to make responding more focused? If you mean you want to:
A) compute the difference (in days) between two date in the same row, then
B) find the max duration (in days)
Here is my take on this problem:
D2 = C2-B2
select D2 and fill down
F1=MAX(D)
to perform the conditional formatting (to highlight the max duration) select column D, then set up conditional formatting as shown in the 1st image -
Calculate Difference in Days Between two Dates
Hi,
I'm trying to figure out how to calculate the difference in days between two dates using JavaScript in LiveCycle. (JavaScript knowledge = minimal)
Where "Start_Date" and "Current_Date" are the names of the two dates in the Hierarchy palette. (both Date/Time Field)
*Current date is using the Object > Value > Runtime Property > Current Date/Time
I need a Text or Numeric field displaying the difference in days. (Difference_in_Days)
I've noticed the following code being pretty standard amongst other responses:
var
Start_Date = new Date(Start_Date);
var
Current_Date = new Date(Current_Date);
var
nAgeMilliseconds = Current_Date.getTime() - Start_Date.getTime();
var
nMilliSecondsPerYear = 365 * 24 * 60 * 60 * 1000;
I know there's code missing, and the above code might not be correct.
Please advise.Where "DateField01" = user entered date field
Where "DateFiled02" = Current Date/Time (Runtime Property)
where "Subform" = the subform containing DateField01
My script now resembles:
var oneDay = 24*60*60*1000;
var firstDate = new Date(Subform.DateField01.rawValue);
var secondDate = new Date(DateField02.rawValue);
(firstDate.getTime() - secondDate.getTime()) / oneDay;
I tried adding:
app.alert(String(diffDays));
Although I assume the reason I didn't get an error is because DateField01 is empty when the form is opened.
If I swap in actual dates instead of fields it works perfectly.
When I use the fields I have no information populating after I enter a date in "DateField01" -

getTime returns millsecond value of date object and the difference divided by no of milliseconds in a day should fetch you the difference in terms of days.This doesn't respect the DST. Use java.util.Calendar. -
How to query the number of working days between two dates
I'm looking for a solution to calculate the number of <i>working</i> days between two dates that I can use in a formated search.
Calculating the total number of days is pretty straight forward but does anyone know how to take into account the settings in the HLD1 (Holiday Dates) table?Hi Eric,
If you are purely looking to exclude holidays defined in the HLD1 table, then you should be able to do it with the following query
NOTE: The following query is an example using OINV table and the fields DOCDATE and DOCDUEDATE for a Particular DOCNUM 'xxx'
If you planning to use within the SAP module then replace DOCDATE and DOCDUEDATE with dynamic field references $[$x.x.x]
SELECT DATEDIFF(DAY,T0.DOCDATE,T0.DOCDUEDATE)-
(SELECT COUNT(STRDATE) FROM HLD1 WHERE STRDATE >= T0.DOCDATE AND STRDATE <= T0.DOCDUEDATE)
FROM OINV T0
WHERE T0.DOCNUM = xxx

How to calculate number of days between two date in Template design?
Hello guys
I have a situation where I have to create a template that returns data, and one of the thing of the existing report is that there is a column that is actually the number of days between start date and end date columns..
So in template, how would I be able to do the same? I have start date and end date columns on the template, now when I created another column using expression like end date - start date and preview the template, I am getting errors saying :
Caused by: oracle.xdo.parser.v2.XPathException: Cannot convert 03/31/2009 to number.

ThanksHi
There is an extension function you can use, from the javadoc:
date_diff
public static long date_diff(java.lang.String format,
java.lang.String fromDate,
java.lang.String toDate,
java.lang.String locStr,
java.lang.String tzID)
Method to get the difference between two dates in the given locale. The dates need to be in "yyyy-MM-dd" format. This function supports only Gregorian calendar.
Parameters:
format - the format to which the difference is required; allowed formats are y (for Year), m(for month), w(for week), d(for day), h(for hour), mi(for minute), s(for seconds) and ms(for milliseconds)
fromDate - the first date
toDate - the second date
locStr - locale string -> lang-Territory
tzID - timezone ID ->http://java.sun.com/j2se/1.4.2/docs/api/java/util/TimeZone.html
Returns:
the difference in dates in the desired format
For example
<?xdoxslt:date_diff(‘d’,’2009-09-14’, ‘2009-09-20’,’en-US’,1)?>
give a result of 6
You can substitute in columns for the dates, just remember the date format required.

How to retrieve day between two dates?
Hi all,
Hope doing well,
sir i am retrieving day between two dates in sql server like this.
select datediff(day,'2012-10-03 00:00:00.000','2012-10-05 00:00:00.000')
and getting result that is: 2
but how this type of query i'll use in oracle?
thanks,Just do minus

If you want just the differences in days (Neglecting time part)
diff := trunc(date2)-trunc(date1); -
Find Exact number of days between two dates
How can get the exact number of days between two dates?
An example of business days calculation in SQL */
/* The algorythm is: */
/* 1) Take the absolute difference between the dates */
/* to_date('&todate') - to_date('&frdate') */
/* 2) Subtract the weekends (number of weeks in the range */
/* TRUNC(to_date('&todate'),'D') = 1st day of week that */
/* end of period is in */
/* TRUNC(to_date('&frdate'),'D') = Last day of week that */
/* start of period is in */
/* So subtracting these two gives the number of days */
/* between the two dates but including all of the days in */
/* the weeks that the dates start and end in. When this */
/* number is divided by 7 it gives the number of weeks. */
/* Multiplying by 2 gives the number of weekend days. */
/* 3) Subtract 1 day if the ending date is on a saturday */
/* DECODE(to_char(to_date('&todate'),'D'),7,-1,0) */

Calculate business day between two dates
Hi Guys
I need the count of business days between two dates
Date1, Date2 i need the count only business day (exclude sartuday&sunday)
If date1 is null or nothing i need to pass 0
If date2 is null or nothing i need to pass 0
help on thisHi,
To achive this within SSRS, go to the report code window and add the below
Function getBusinessDaysCount(ByVal tFrom As Date, ByVal tTo As Date) As Integer
Dim tCount As Integer
Dim tProcessDate As Date = tFrom
For x as Integer= 1 To DateDiff(DateInterval.Day, tFrom, tTo) + 1
If Not (tProcessDate.DayOfWeek = DayOfWeek.Saturday Or tProcessDate.DayOfWeek = DayOfWeek.Sunday) Then
tCount = tCount + 1
End If
tProcessDate = DateAdd(DateInterval.Day, 1, tProcessDate)
Next
Return tCount
End Function
In the textbox where you need to display the value, add the below expression
=Code.getBusinessDaysCount(parameters!StartDate.Value,parameters!EndDate.Value)
It is assumed the you want to pass the two days from parameters named Startdate and EndDate. If not, modify the expression with required values.

Working days between two date fields and Changing Factory Calendar
Hi,
I have to calculate working days between two date fields excluding the weekends and public holidays for Switzerland.
I have written the routine using factory calender and its working fine except for two problems now:
1. If any one of the date field is empty then teh rsult should be zero.
2. And the below code is working from 1996 but my cleints wants it to work for years before 1996 as well.
I also tried to change the Start date in SCAL for factory calendar but it says enter values between 1995 to 2020.
I am new to ABAP. Please help me how i can achieve these for below code.
DATA: IT_HOLIDAYS type TABLE OF ISCAL_DAY,
IS_HOLIDAYS TYPE ISCAL_DAY.
DATA: T_DATE TYPE SY-DATUM,
P_DATE TYPE SY-DATUM.
DATA : X_DATE(4) TYPE C.
DATA: CNT TYPE I.
REFRESH : IT_HOLIDAYS.
CLEAR : IT_HOLIDAYS.
T_DATE = SOURCE_FIELDS-/BIC/ZCCCHP812.
P_DATE = SOURCE_FIELDS-/BIC/ZCCCHP810.
CALL FUNCTION 'HOLIDAY_GET'

OTHERS = 5.
DESCRIBE TABLE IT_HOLIDAYS LINES CNT.
X_DATE = T_DATE - P_DATE - CNT.
RESULT = X_DATE.
Please help

Try this function module 'DURATION_DETERMINE'.
Give the factory calendar and unit as DAY
