  How to calculate the number of months between two dates

  Opening date: 20/02/2014

  Closing date: 20/03/2015

  Terms of months: 13

  How I get the year and subtract and multiply by 12 and then add it to the difference of the month? Sorry that I am not well versed in the scripts.

  Thanks in advance.

  In this way, you have provided the example. You can change the constant string to the necessary code to get the value of a field. You can add additional to prevent code by using the code until the two fields have a non-null value.

• Calculate the number of days between two dates

  Hello

  Can someone help please change my formcalc script to calculate the number of working days between two date fields.  My script currently calculates the total number of days between two dates, including the weekends which must be excluded from the total.

  If

  (HasValue (Start_Date1) & HasValue (End_Date1)) then

  $

  = Date2Num (End_Date1, "YYYY-MM-DD" "en_IE") - Date2Num (Start_Date1, "YYYY-MM-DD" "en_IE") + 1

  on the other

  ""

  endif

  Any help will be most appreciated.

  Thank you.

  Check...

  (1) you said that you put the script on the event «days1» calculate My sample imitates the variable names used in the original message, "Start_Date1" and "End_Date1". If the names of variables for the start and end dates are different, you will need to modify the script to account for these names.

  (2) the Date2Num functions in the calculation of the "totalDays" use the date format "YYYY-MM-DD". If your date habits differ from "YYYY-MM-DD" FormCalc will complain.

  I use the version of database Oracle 11.2.1. I would like to calculate the number of fiscal month of a date.
  
  For example:

  SELECT mydate, EXTRACT (MONTH FROM (ADD_MONTHS (mydate, -3))) fiscal_month

• Calculate the number of fringes

  Is anyone know the feasibility of the use of the Machine Vision or LabView to calculate the number of fringes in each region? (Attached image). I want to count how many white line on each region. For example, on the attached picture, there are about 6 regions and each region will display the number of the white line in their own region. For information, I have V8.5 of LabView and NI Vision Assistant V8.5. Please, give me some ideas on how to solve it.

  Thank you.

• Calculate the number of days remaining until the next anniversary. Help, please!

  Hi guys,.

  I'm new to the forum and to the development of BB. So please do not judge harshly if the answer to my question seems obvious.

  I need to calculate the number of days until the next birthday (taking into account any valid birth date)

  After looking at the API and the forum search, I realized that I could

  calculate the difference between two dates in milliseconds and then divide the delta of the value of a day in milliseconds. That is to say:

  birthdayCalendar.set (Calendar.YEAR, those);

  Date1 = birthdayCalendar.getTime () .getTime ();

  date2 = System.currentTimeMillis ();

  Delta = date1 - date2

  numOfDays = delta\DateTimeUtilities.ONEDAY

  Here's my question. How do I create a valid date1 what about leap years?

  Maybe there's a better way to solve this problem?

  Any help is greatly appreciated.

  I agree that the determination of the number of days between today and Feb. 29 could be a little difficult, if it is not a leap year.  I suspect that the calendar has a certain built-in mechanism to compensate for this, but your solution to choose a date is better.

  DST has a role to play, and Yes, the calendar makes up for it.  Let us take two dates, for example (before DST) March 1 and June 1 (after the DST).  If you take a calendar and set the same hour, minute, etc., they are all the same except for dates, then subtract one from the other, and then divide by the number of milliseconds in 1 hour, you calculate the number of hours between the same time on two different days.  You will find that it is not a multiple of 24 hours - because there is actually an hour less than the number of days since the clocks move forward (in the northern hemisphere anyway...),

  In your case, you are not calculating the number of hours, you calculate the number of days.  But you will be dividing by [24 * (time in an hour)].  If you take [23 * (time in an hour)] and divide it by [24 * (time in an hour)], using arithmetic on integers, you will end up 0.  The easiest to get around this, who also works for the end of the DST too, is to simply add one hour to the date before the division.

  Hope that makes sense...

• Essbase calc script to determine the number of occurrence

  Hello

  is it possible within a calc script to determine the number of occurrence of a value in the account dimension?

  I have an account called ranks which can contain any value between 1 and 10.  I would like to know how many times each value is repeated for a specific cost center.  It's in a database of planning BSO.

  Thanks in advance for your contributions...

  CL

  This isn't the typical calculation you would do in an OLAP architecture, but yes it is certainly possible.

  you will need to create 10 accounts such as occurrence_of_1, occurrence_of_2 etc.

  Then you increment them according to the value of the 5th year.

  Don't forget to put in your calculation!

  Hello

  So, you want to count the distinct months for 6 months before (not included) the given month; is this fair?

  Here's one way:

  VARIABLE month VARCHAR2 (2)

  Year VARIABLE VARCHAR2 (4)

  EXEC: months: = '4';

  EXEC: year: "2014"; =

  WITH got_end_date AS

  (

  SELECT TO_DATE (: month |) '/' || : year

  , ' MM/YYYY ".

  ) AS end_date

  OF the double

  )

  SELECT a.empid

  , COUNT (DISTINCT

  CASE

  WHEN a.unpaid > 0

  THEN TRUNC (a.payrolldate, 'MONTH')

  END

  ), Cnt

  Of attendancesheet one

  JOIN e-got_end_date WE a.payrolldate > = ADD_MONTHS (e.end_date-6)

  AND a.payrolldate< >

  GROUP BY a.empid

  ORDER BY a.empid

  ;

  If you use a WHERE clause to exclude the lines with some outstanding = 0 (or unpaid is NULL), then you would get no output for employees like empid = 2 in this example.  A WHERE clause ignores an entire line, so I used an expression BOX just a value.

• Basic conditional script based on the number of lines in a text layer?

  Just received help here to write a conditional script by using the font size of a text layer. Thank you all for this.

  The next hurdle is a conditional script using the number of lines in a text layer in the differential. Far as I can tell it not the layer details which specify the number of lines. Just '\r' for a return in the idTxt descriptor. Nothing seems to stand for a soft return as far as I can tell. I'll probably have to be able to count the lines with soft and hard returns.

  Any thoughts?

  I was playing around with this a bit and here is a small script to determine the number of rows. This is based on the self in the head, that I calculated to environ.108 times the size of the font.

  #target photoshop
  app.preferences.rulerUnits = Units.POINTS;
  var doc = activeDocument
  var tL = doc.activeLayer
  var h = tL.bounds[3]-tL.bounds[1]
  var per = ((h/5)-(tL.textItem.size))/tL.textItem.size
  var num = h/(tL.textItem.size *1.108)
  
  alert(Math.round( num))

• Get the number of month, week and day between 2 dates

  Hi all
  
  Is it possible to display the number of months, weeks and days between 2 dates? by using only the SQL or PL/SQL...
  
  Entry:
  Date: October 1, 2010
  Date: October 19, 2010
  
  I want output like below (assuming starts the week from Monday to Sunday in oracle).
  
  October 1, 2010-(since it's in the middle of the week)
  October 2, 2010-(since it's in the middle of the week)
  October 3, 2010-(since it's in the middle of the week)
  40. (4 Oct-10 Oct falls into the 40th week of the year)
  41. (11 Oct-17 Oct falls into the 41st week of the year)
  October 18, 2010-(since it's in the middle of the week)
  October 19, 2010-(since it's in the middle of the week)
  
  
  Note: If there is a month between the date, the number of the month should be displayed.
  End of the month, the remaining date included with a full week, then the week of the year number should
  displayed. After posting the week, remaining dates should be displayed as it is...
  
  
  Appreciate your help...

• Calculate the previous three months

  I want to calculate the past 3 months on the basis of sysdate in 3 separate columns. I get the previous month by executing the following SQL statement:

  select EXTRACT(MONTH FROM TRUNC(SYSDATE,'MONTH')-1)mn1 from dual

  The current month is July, then how can I get 05, 04 as output.

  Hello

  Just remove TRUNC...

  select EXTRACT(MONTH FROM (SYSDATE))-1 mn1,EXTRACT(MONTH FROM (SYSDATE))-2 mn2,EXTRACT(MONTH FROM (SYSDATE))-3 mn3 from dual;
