How to get a time part from Date datatype

Hi,
I would like to know how to extract the timestamp alone from DATE datatype? If my input is '27-SEP-2011 23:59:00' I need the output as 23:59:00. I am surprised to see that there are no in-built functions for this or may be I am wrong. Basically I need to remove the date part from DATE data type and get the time.Please assist.
-Thanks

There is a built-in function, TO_CHAR:
TO_CHAR (dt_col, 'HH24:MI:SS')Depending on how you plan to use the time, TRUNC is another handy built-in function:
dt_col - TRUNC (dt_col)is a NUMBER (not less than 0, but less than 1) which is suitable for many tasks, such as finding the average time.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

Select all the photos that you need to change, then click the "Photos" menu and choose "Adjust Date and Time".
If you add a year, it will adjust all the photos that you selected by adding a year (so if you accidentally select one of the photos that already has "2012", that will change to "2013").

How to get current time and date??

How to get current time and date from my PC time and date to the java application??
i use java.util.* package but got error, that is:
- java.util.* and java.sql.* class are match
- abstract class cannot be instantiated
so what can i do, pls guide...thanks...

There is a method in the System class that will return the current system time. You could also instantiate a Date, Time, Timestamp, or Calendar object, all of which get created with the system time by default.
Don't import *. Import the specific classes you need.
Next time, post the actual text of the exceptions/compile errors. If you make people guess, most just won't bother.

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

How can get 40,000 pix from old computer restored by Carbonite to new computer into PE 11 or 12?

I bought a new, faster, more storage Windows 8 computer.
I had 40,000 pix on old computer tagged with names, event, location, date with PE 11. Also several projects involving hundreds of pix.
Carbonite restored all files (250 gig) from old computer to new, and their tech support says they all are on the new computer.
I bought the new PE 12 and installed it on new computer. It has only found 4,000 pix. I don't at all like PE 12 after enjoying PE2-11 and managing all my pix with it. PE11 was clearer in the pix presentation.
Apparently when imported to the new computer, I lost the tags that went to events, location, and the person tags did not separate family from friends etc. I can't even find my projects.
I was so frustrated with PE12, that I installed PE11, but everytime I try to open the Organizer, it doesn't open.
Help. I am so frustrated. I am pretty sure before I made the transition that I had written all tags to files. When I put PE11 on the new computer, why won't it give me what I had on the old.
This is probably my 10th generation computer change, and I never had such problems before with PE.

I am using 10 and 11 instead of 11 and 12. I tried to go back and edit,
but couldn't figure out how. Sorry, typing errorC.

Hi,
Thanks for the suggestion. I've been playing around with some of the classes of the java.net package and java.io
Using the URL class i can get the content of the data from a STATIC page and output that response to file so that is does not display to the client broswer.
But this only works if the URL i give points to a static html page.
So the problem i'm getting is if i'm righting in arguments in the URL, this means that server needs to process the arguments i give and its sends back a dynamic result. Because its dynamic the URL class can not handle this and throws me an exception everytime :(
Have u ever tried to do some things like this?

1) Whenever you pivot rows to columns, no matter what version of Oracle and no matter what method you use, you have to decide in advance how many columns you are going to have and what the names of the columns are. This is a requirement of the SQL standard.
2) I use the WHERE clause to get just the data for this year
3) With EXTRACT, I get just the month without the year.
4) Using DECODE, I put every month's data into the correct column
5) Once I do all that, I can just GROUP BY order_code while SUMming all the data for each month.
