Convert sysdate to a julian date 'YYDDD' format to a number format

Hi
I need to be able to convert sysdate to a julian date 'YYDDD' and update the julian as a number data type. Thanks for your help.

Hi,
Use TO_CHAR to get a string representation of a date, such as '110008'.
Use TO_NUMBER to get a NUMBER represnetation of that string.
SELECT TO_NUMBER ( TO_CHAR (SYSDATE, 'YYDDD'))
FROM dual

It looks like you accidentally posted 3 copies of the same question, and then, after you realized the msitake, marked them as "Answered". That's very considerate of you. It would be even better if you changed the subject line of all but one of them to "Duplicate - Sorry!"; the remaining one you can leave as "Unanswered" until it really is.

Convert string (in a Julian Date format) to a date in CR XI Release 2

How do you convert a string field entered in a database as a Julian date " 10109 , 09008. ,,," to
print on a report as date?
09008 would be 01/08/09
10109 04/19/10

A small correction to Brian's formula:
NumberVar myYear;
NumberVar myDays;
myYear := ToNumber( {table.JULIAN} [1 to 2]);
myDays := TONUMBER({table.JULIAN} [3 to 5]);
(Date (myYear, 1, 1) + myDays) - 1;
The result for '09008' will be 01/08/9, by adding ToText, you can get the result in the desired format of 01/08/09.
totext((Date (myYear, 1, 1) + myDays) - 1, "MM/dd/yy");
Here is an alternate solution without having to create variables:
totext(dateserial(tonumber(X[1 to 2]),1,tonumber(X[3 to 5])),"MM/dd/yy");
where X is the julian date in string.

Function module to convert calender date to Julian date format

Hi,
Is there any FM which can convert Calendaer Date to <b>Julian Date</b> format?
Thanks.
Regards,
Madhu

It is not a func mod... but it is pretty straight forward.
data: julian_day(3) type n,
date_aux type d,
date_I_need type d.
first day of the year
concatenate date_I_need(4) '0101' into date_aux.
julian_day = date_I_need - date_aux.
julian_day = julian_day + 1.

Julian Date for use in Document ID

Can anyone show me how I can convert a date field into a Julian date(YYDDD)? Essentially I just want to have this converted into a variable that I will concatenate with other values that will be used in generating unique doc ID.
Additionally anyone have thoughts on how I can ensure the doc ID is globally unique w/o using getUID?
I have never done anything with a Julian date before so I am at a loss.....

Hi,
to display a julian date you can use the J symbol in your display pattern:
date{YYJ} to display January the 3rd 2015 as 153 (3rd day in 2015)
or
date{YYJJJ} to display January the 3rd 2015 as 15003 (with leading zeros)
To reuse the formatted Date in a script use the formattedValue instead of the rawValue.

thanks a lot....for intrest....
I have found some details about the Julian calendar as follows:
The Julian date for 2006: JAN: 01:12:01:59 is 2453737.00138
245 represent the year digits for year 2006
3737 represent the date fir 1 Jan
.00138 represents the time for 12:01:59
Julian date change as per every day 12 noon it increase one digit in it.
As per ref from
http://www.aavso.org/observing/aids/jdcalendar.shtml
Also chk this calendar where Julian date is 20. October 2006 for 02 November 2006
As per ref from
http://www.calendar.sk/julian_calendar-en.php
I have tried the pure �GregorianCalendar� class from jdk1.4 API and its setGregorianChange method but not getting as per the expected Julian date format. Using the �setGregorianChange()� i have setting the cutover date to Long.MAX_VALUE it means GregorianCalendar now have to act as per the Julian calendar ...so after setting the cutover date it return me changed date using �getGregorianChange()� but that was not the Julian date of the current date...as expected or as per above both scenario. Even though the last two digits are nowhere equal to the actual Julian date.
Program
GregorianCalendar cal = new GregorianCalendar();
cal.setGregorianChange(new Date(Long.MAX_VALUE)); // setting the calendar to act as a pure Julian calendar.
// cal.set(Calendar.DATE, new Date().getDate()); // seting the current date
// Date todayJD = cal.getGregorianChange(); // getting the changed date after the setGregorianChange
Date todayJD = cal.getTime(); // getting the calculated time of today�s Julian date
SimpleDateFormat sdfJulianDate = new SimpleDateFormat("yyDDD");
SimpleDateFormat sdfJuliandayOfYear = new SimpleDateFormat("DDD");
System.out.println("today Date = " + new Date());
System.out.println("Today as julian date = " + sdfJulianDate.format(todayJD));
System.out.println("Today as day of year = " + sdfJuliandayOfYear.format(todayJD));
OUTPUT:
USING : Date todayJD = cal.getGregorianChange();
Today Date = Thu Nov 02 15:17:05 IST 2006
Today as julian date = 94229
Today as day of year = 229
USING : cal.set(Calendar.DATE, new Date().getDate());
Today Date = Thu Nov 02 15:19:22 IST 2006
Today as julian date = 06319
Today as day of year = 319
USING : Date todayJD = cal.getTime();
Today Date = Thu Nov 02 15:17:59 IST 2006
Today as julian date = 06306
Today as day of year = 306
There is one another concept i found to get the Julian day of the year as per the Julian day chart mention on nasa site (http://angler.larc.nasa.gov/armsgp/JulianDayChart.html) and i m getting the moth of the year that is 306 for nov 02 2006 using getTime() method in above code then the out put is right for Julian day. But it was not as per the expected Julian date format. So in conclusion we can only able to retrieve the day of year for the Julian calendar. hope their will be a solution for this problem in java api ....else we allways have to depend upon the third party api that was not accepteble some times.....
Kindly chk chart on the site

Julian dates

I have a file that reads in date
MMDDYYYY from the user.
I need to pass this parameter somewhere to convert it
into a julian date. I will later use this julian date to query a database based on the start and ending date criteria.
How do I make the conversion?

How to Convert Normal XML date or Oracle date to JDE Julian Date

We can do a simple mathematical step in XSLT :
'xpath20:format-dateTime(xpath20:current-dateTime(),"[Y0001][d001]") - 1900000'
Or in SQL :
Select to_char(sysdate,'YYYYDDD')-1900000 from dual;
Julian Date is: Year in 4 digits, YYYY, and Number of days in 3 digits, DDD
JDE Julian Date is Julian Date -1900000 (ie it counts Julian date from 1900 Year)
"[Y0001][d001]” returns date in Year in 4 digit + number of days in 3 digits. This is the Julian date.
Subtracting 1900000 ( ie YR ’1900’ & DAY ‘000’) gives the required JDE Julian Date.

How to convert sysdate to the format dd-mon-yyyy

how to convert sysdate to the format dd-mon-yyyy

<how to convert sysdate to the format dd-mon-yyyy>
This question is better answered by thinking about about how Oracle dates work. SYSDATE is a pseudocolumn (function without any arguments) that returns a date value: it already is a date. Oracle date values are stored not as we see them, say 'DD-MON-YY', but as a series of bytes with the different date components from the millennium down to the second. We NEVER see dates as they are stored but use the formats for automatic conversion.
To display a date the way you want use TO_CHAR() with an edit mask or as others suggested change your NLS_DATE_FORMAT (thought I advise against this as most systems use DD-MON-YY and porting queries from other systems or even OTN can easily break). To change a converted string back to a date use TO_DATE() with an edit mask.

Hello,
searching the Internet I found this formula how to convert Gregorian Date to Julian Date:
http://aa.usno.navy.mil/faq/docs/JD_Formula.php
Converting this to PowerShell and running with "Run .Net Script" Activity works:
Why not simple use "Format Date/Time Activity" to use the Gregorian dates?
The example above will return 201307232 as "Format Result" now.

How do I convert an 8 bit serial data string I have received (say 01110101) into decimal format??

When you have your front panel displayed, you should a whole palette of controls that you can place on the front panel. If the palette is not displayed, thne just right click on your mouse and it should appear. The upper left most set of controls on the palette is Numeric. Go there and select Numeric Indicator to display a numeric output. On the diagram, you can also right click the output 1 and select Create>Indicator. The format string is %b (as in boy) for a binary string. As I said, this should be the value for the format string input. You can right click on the Scan From String and select Edit Scan String. This will bring up a dialog box in which you pick what you want to do (Scan Number) and how you want to do it (Scan Binary Integer
It sounds like you really need to take a course in LabVIEW programming. There are are links here to NI classes and some on-line tutorials.
