Subtracting two timestamps and showing the number of hours between them.

Hello Folks,
What I have is two tables, each of them has a timestamp column. I want to do a select with a join that will show a column with the number of hours between the two times.
(I have added the columns as timestamp(0) since I have no need for the decimals)
Here's what I have:
table one name: conc_test
table one info:
P_DATE-------JOB_NO-----MIX---POUR_NO----AMB_T---CONC_T--SLUMP---AIR---DENSITY---CYL_CAST_TIME
09-MAR-10---9-12-796-----80----100309A------2.5--------16----------135------2.5----2501-------09-MAR-10 10.00.00 AM
table two name: rls_break
table two info:
JOB_NO----POUR_NO-----CYL_ID----SPEC_STR---STR----MIX---BREAK_D_T
9-12-796---100309A----100309A1------20-----------27-----80----10-MAR-10 07.15.00 AM
(I put the --- between the columns so it would be more legible for forum reading, fyi)
This is what I was trying to do:
select
rls_break.cyl_id "Cylinder ID",
rls_break.mix "Mix",
trunc(rls_break.break_d_t-conc_test.cyl_cast_time) "Age",
rls_break.spec_str "Specified Strength",
rls_break.str "Specimen Strength"
from rls_break inner join conc_test on rls_break.pour_no = conc_test.pour_no
where pour_no = '100309A';
I want the "Age" column to show the total number of hours between the cast time (column cyl_cast_time from conc_test) and the break time (column break_d_t from rls_break)
Thank's for any and all help.

(I put the --- between the columns so it would be more legible for forum reading, fyi)Please put the tag before and after your examples.

How to use TextField to add two numbers and show the result.

hi everybody
i would like to use JTextField to get addtion of two Numbers,
for example i am trying to type any integer numbers in JTextField like 7
and press JButton, called( +) to add anthor number like 7 and press JButton called(=) to get addtion fo
7 + 7 = 14, at same JTextField.
so there will be two buttons, one for (+),other for (=).
i have implement ActionListener in (+) button ,to get Text from JTextField (with getText() method),
now how do i use same getText() method to get the next number that i will add it with previous number in
(+) button and get the result whenever i press (=).
1-type integer number like (4) in TextField.
2-press addition button(+) to get text by using getText() method and clear TextField.
3-type anthor integer number like(6).
4-press (=) button to get the number (6) by using getText() method, calculate 4 + 6 and show the result at same TextField (10).
i hope it is so clear
thank u in advance for any advice and suggestion.

Use your first button to
String x = JTField.getText();
int y = Integer.parseInt(x);
this will get your first value on your + button. Make sure you initialise the int beforehand incase nothing is put in (ie error prevention) then clear the JTField prob using setText(""). Repeat the process for the = button using different variables and add them normally and output the result.
If your putting more than 1 arithmetic button on the GUI then you'll need to distinguish between them!!!

Get number of hours between two dates and two hours using factory calendar

Hello all,
I have the following requirement: I need to calculate the number of hours between two dates and two hours (start date- finish date and start hour-finish hour) or timestamps using a factory calendar. I must program it on CRM environment.
Does anybody know a function module that makes it?
Thanks in advance.

FM to find the difference in the number of hours

hi all,
is there any function module to find out the difference between two time stamps on two different dates. say if an activity starts on 09/05/2007 at 11:23:24 and ends on 09/08/2008 at 14:24:26. it needs to find the number of hours between the two. for this case it should be:
75:01:02 hours:mins:secs.
or a FM which works in a way similar to the above functionality.

Hi,
Use FM SD_CALC_DURATION_FROM_DATETIME
but this will not give the seconds difference

Workflows: How to set a workflow variable that is the difference in hours between now and a created date

I'm trying to create a variable that contains the number of hours between the item created date and Now. When i use TODAY, it seems to set the time at 12:00 rather than the time now - so that throws the hours off. Any ideas?
ajw

Hi ajw,
According to your description, my understanding is that you want to calculate the hours between the item created date and now.
It seems to be not an OOB way to implement your requirement, to get the current time, you need to create a custom workflow activity for SharePoint 2010 workflow. About creating custom workflow activity, you can refer to the links below:
http://msdn.microsoft.com/en-us/library/hh872790(v=office.14).aspx
http://blogs-sharepoint-ashutoshmisra.blogspot.in/2013/02/create-custom-workflow-action-for.html
Or, you can use a third party solution to achieve your requriement.
Here are some similar posts for you to take a look at:

Count number of hours between dates excluding holidays/weekends

Hello all
I havent worked with dates extensively and was recently asked to create a report where Im looking for the number of hours between two dates only counting business days.
So for example I have data as follows
Created 2011-03-30 15:00:00
Processed 2011-03-30 15:03:46
Fulfilled 2011-04-01 17:25:02
Mailed     2011-04-01 17:45:00
For a total of looking from the CREATED and MAILED dates
50 hours 45 minutes
Im also trying to exclude weekends and holidays, i was reading around and was actually able to also find a table of dates where I have the main date, HOLIDAY_IND column and WEEKDAY_IND column
So the calender table i have looks similar to
CALENDER_DATE HOLIDAY_IND WEEKDAY_IND
2011-03-31 Y Y
2011-04-01 N Y
2011-04-02 N N
Im really quite stumped as to where to begin
I was thinking of trying to write it with PL/SQL but i dont have the proper user access to create procedures/functions, so looks like straight up SQL
Any help appreciated!

Hi,
Depeneding on your data and your requirements, you can do something like this:
SELECT     created_DATE,
,     mailed_date
,     24 * ( (mailed_date - created_date)
            SELECT COUNT (*)
            FROM        table_o_dates
            WHERE    main_date > created_date
            AND        main_date < TRUNC (mailed_date)
            AND        (   holiday_ind = 'Y'
                     OR weekday_ind = 'N'
           )               AS hours_between
FROM     table_x
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.
What do you want to do if created_date or mailed_date is not a work day? Include examples in you data and results.

Although my ipod shows the number of steps, calories, and time, it no longer is saving it to the history. also when I open the history it takes me to May 2010 instead of the current date. Any ideas on how to get it to start recording the history again?

How can i take the number of a random process to use it in math´s and show the solution to the user?

i wrote this function and i try to show the number of seconds the user was to early or to late to click the stopbutton to the user.
its about to hit stop intuitiv while in the background ther is a random number already made but the user dont know or see it.
the eyes opens in a random between 100 and 40000 millisec. if they open up the user should click stop without seeing them. so its intuitiv.
i just tryed.
this code is on the mc with the eyes to let them open randomly. it is on the second frame at the main time code. 1st frame is the start button and a small description. on the second the stop button and the closed eyes with the script down here as i already said. and on the 3rd frame is the end wher it should be shown to the user. thats how i tryed. please let me know any suggestions and or other solutions to my problem! If you need to see my flashfile to help me just let me know. i send it to you or something :-)

Finder issues and Get Info refusing to show the number of files on items on the main hard drive.

I am having finder issues. Mostly on the main hard drive. It takes ages to find things and I get the spinning wheel every time I open a folder.
So I moved all of my files to a external drive. When I had finished transfering I hit get info on the files on the external drive and on the same folder on the main drive. To ensure that it has copied over all the files. Because it was acting up and not copying all the files.
Get Info refuses to show the number of files within the folders on the main hard drive. It hasppily tells me everything on any of the external drives.
I have reset, the imac. I have re indexed 3 times. I have deleted the finder plist files. I have reset finder using terminal commands. I have moved nearly everything off the main hard drive. But nothing is working.
Can anyone offer any suggestions as to what could be causing my finder and get info issues.
Any help wpuld be appreciated.

Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Back up all data.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
sudo find ~ $TMPDIR.. -exec chflags nouchg,nouappnd,noschg,nosappnd {} + -exec chown $UID {} + -exec chmod +rw {} + -exec chmod -N {} + -type d -exec chmod +x {} + 2>&-
This time you'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button
Select
 ▹ Restart
from the menu bar.

Have you tried HELP in FINDER? If you open HELP and enter 'displays' in the field in the upper right hand corner you will get a list of topics on setting up monitors. Specifically read 'Setting up multiple displays to show the same image' and 'Setting up multiple displays as an extended desktop'.

Is there a way to hide and show the whole 3D viewer with javascript?

I'm trying to set up a pdf so that the person who's reading it can use a button to switch between a picture of the product and a 3D model of the same. The idea is that the two ways of illustrating the product can be in the same space, so that there's still room to put enough text on the front page. I have spent about three hours trying to figure this out.
Even if I hide the model withtin the 3D viewer and make the background transparent, the 3D viewer is still there, intercepting mouse clicks and showing the toolbar.
I've tried modfiying the Annot3D, by moving it off the page, because the javascript reference says that the "rect" property of Annot3D can be written, but the viewer just stays in the same location.
Is there any way to get the whole thing to go away with one button click and come back with another?
Thank you for your help and patience,
Daniel,
PS - In the past I've placed product drawings and pictures in the same place by putting them on separate layers, but I can't figure out how to get the 3D display attached to a layer.

One way you could get the same effect is to use separate pages. Disable the mouse scroll for switching pages and instead use buttons to go from one page to the other. The user will get the impression that the annotation has appeared and disappeared.
Another hack is to use the product information as the icon on the annotation, so just disable it when you want to show the product information and make sure it lines up with an overlay of surrounding product information.

How do you show the number of days per month?

How do you show the number of days per month?
I am working on a budget. I want to know how much to amortize each month to fund an investment. Income comes monthly, but expenses leave in days, or weeks. The number of days and weeks in months vary.
I want to figure out income and expenses per day, per month and per year, so I know how much can be invested each month, week or day. For a start I would like a formula that shows how many days are in each month?

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);
}

Subtracting two timestamps and showing the number of hours between them.
