  • Find the difference between two date and time

    Hi friends,

    I wanted to find the difference between two date and time, but my qury is slightest error "invalid number."

    select sql_step_num,proc_name,run_seqno,start_date,end_date,(to_char(start_date,'HH24-MI-SS') - to_char(end_date,'HH24-MI-SS') ) as ed

    You try to get the feel between two char strings.
    And more difference between two dates gives a NUMBER of days.
    Try this:

  • Simple query to find the difference between 2 numbers in one column to another column

    Hello

    I would like to know the difference between 2 numbers in same column corresponding to a condition of another column. How do that?

    For example: say I have a table with 3 columns A, B and C.

    A > Varchar2

    B > Varchar2

    C > number

    A B C
    AD1
    BC2
    CB3
    DA4

    I want something like 'column value corresponding C min min (col B) result = (col A) - value of the corresponding C column (number)' without having to write 2 select statements. How do I do that?

    Thanks in advance

    Hello

    It is not very similar to your original question.  It would be better if you asked what you really want in your first post, rather than making people to time writing solutions you want not and can not use waste.  Once you see an answer to this question, will you change the question again?

    Here's a way to do what you asked:

    WITH got_lasts AS

    (

    SELECT val.thread #.

    , MAX (val.sequence #) AS last_standby_seq_received

    MAX (CASE

    WHEN val.applied = "YES".

    Hi Navin,

    TIMESTAMPDIFF function first determines the timestamp component that corresponds to the specified interval setting. For example, SQL_TSI_DAY corresponds to the day component and SQL_TSI_MONTH corresponds to the component "month".

    If you want to display the difference between two dates in days using SQL_TSI_DAY, unlike butterflies SQL_TSI_MONTH and so on...

    hope you understand...

    Hello

    If I unederstand the problem correctly, that's what you want:

    WITH       got_extrema     AS
(
     SELECT       tr_id
     ,       CAST (MIN (create_time) AS DATE)     AS start_date

     GROUP BY  tr_id
)
SELECT       tr_id
,       start_date, end_date          -- If wanted
,       24 * ( ( ( TRUNC (end_date,   'IW')          -- Count -1 day for every full week
                    - TRUNC (start_date, 'IW')
             )
           / -7
              )
            + LEAST ( end_date               -- If end_date is a Sunday
                        , TRUNC (end_date, 'IW') + 6     -- consider it 00:00:00 on Sunday
                 )
            - CASE
                      WHEN  start_date >= TRUNC (start_date, 'IW') + 6     -- If start_date is a Sunday
               THEN  TRUNC (start_date, 'IW') + 6               -- consider it 00:00:00 Sunday
               ELSE  start_date
                  END
            )     AS total_hours
FROM      got_extrema
;

    I guess that you don't need to worry about fractions of a second. As you did in the code you have posted, I am to convert the TIMESTAMP to date values, because of DATE arithmetic and functions are so much better than what is available for timestamps.

    Basically, it's just to find the number of days between start_date and end_date and multiplying by 24, with these twists:
    (a) 1 day is deducted for each week between start_date and end_date
    (b) if End_date is a Sunday, none of the end_date himself hours are counted
    (c) If start_date is a Sunday, then all the start_date himself hours are counted. Why these hours should be counted? Because 1 day is already being deducted for the week which includes start_date, which contains only this Sunday.

    TRUNC (dt, 'IW') is the beginning of the ISO week containing dt; in other words, 00:00:00 the or before the dt last Monday. This is not the NLS parameters.

    Of course, I can't test without some sample data and the exact results you want from these data. You may need a little something more If start_date and end_date are both on the same Sunday.
    Whenever you have a problem, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) of all of the tables involved.
    Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.
    Always tell what version of Oracle you are using.

  • How to calculate the difference between two numbers in text fields

    Hello, I am fairly new to this, and I am certain that I will be bothered by the simple answer is

    I do a simple calculation... total of total assets - liabilities = net worth

    I have my total assets and my total work of the liability, but is not a subtraction option in the properties of a text field for the Net of a field value.

    I don't know... not any script Java can any who help out me?

    Thank you

    Judy

    You can use the option of simplified field notation, but first your input fields names must be changed so that they do not contain spaces or punctuation. For example:

    TotalAssets - TotalLiabilities

    If you want to use JavaScript, what will be needed if you ever in more complicated calculations, you can use something like the following as the custom fields (net value) calculation script:

    (function () {}

    Get the values of the field as numbers

    var v1 = + getField("total_assets").value;

    var v2 = + getField("total_liabilities").value;

    calculate the value of this field

    Event.Value = v1 - v2;

    })();

    There are no restrictions on domain names when using JavaScript.

  • Dynamic action - Get the difference between two dates + times

    I have problems a little dynamic to work action. I'm trying to get the time between two dates with the time difference.

    Here is what I got (this is apex 4.0):

    Two date pickers + two numbers fields (date/start/end times)

    I created a dynamic action on the page who fires on the point lose focus (above points).

    The real action for the DA is the body of the PL/SQL function:
    declare
  end_date DATE;
  start_date DATE;
Begin
  start_date := to_char(:P1_START_DATE || ' ' || :P1_START_TIME, 'DD-MON-YYYY HH:MIAM');
  end_date := to_char(:P1_END_DATE || ' ' || :P1_END_TIME, 'DD-MON-YYYY HH:MIAM');
  :P1_HOURS := end_date-start_date;
End;
    When I change the values on the page, I get the following error:

    AJAX call back Server error ORA-06502: PL/SQL: digital or value error: character number conversion error to set the value.

    I'm guessing that there is a problem with the date formatting, but I can't make it work. Thanks in advance!

    Hi djston,

    because you chose the dynamic action of 'Set value' with the "Body of the PL/SQL function" type you need to return the value. Try the following code

    declare
  end_date DATE;
  start_date DATE;
Begin
  start_date := to_date(:P1_START_DATE || ' ' || :P1_START_TIME, 'DD-MM-YYYY HH:MIAM');
  end_date := to_date(:P1_END_DATE || ' ' || :P1_END_TIME, 'DD-MM-YYYY HH:MIAM');
  RETURN (end_date-start_date)*24;
End;

    and P1_REQUESTED_HOURS like 'item affected. "

  • Formula of FormCalc to make the difference between two time fields if they are populated - help please


    Hello

    I have a laptop (TotalTime1) which refers to two other cells in the updated hour-shaped (Start1 and 1 to finish).

    The formula below is intended to make the difference between the time of departure and of arrival if they are populated.

    I had to work unconditionally HasValue, but the formula was calculated when there is no value in the Start1 and Finish1 (due to the time format).

    This is the code I have, it is said that there is an error of almost the last line; I'm sorry if I'm posting this in the wrong way, I haven't posted on this forum before but this is:

    If (HasValue (Finish1) and HasValue (Start1)) then if (Time2Num (Start1.formattedValue, "HH: mm") < Time2Num (Finish1.formattedValue, "Hh: mm")) then Abs (Time2Num (Start1.formattedValue, "HH: mm")-Time2Num (Finish1.formattedValue, "HH: mm")) / (60 * 60 * 1000) another 24 - ABS (Time2Num (Finish1.formattedValue, "HH: mm")-Time2Num (Start1.formattedValue, "HH: mm")) / (60 * 60 * 1000) endif

    Any help would be appreciated.

    Cordially Fetachini

    you need an another endif at the end (you have nested statement and only 1 endif)

  • The most elegant way to get the difference between two tables - not least!

    Hello


    Simplified example of what I'm trying to achieve - I have two tables ORIGINAL and REVISED.


    My aim is to compare the two, such as; -


    When there is data in the two tables I get the difference between the Budget column, and if there is no difference, so I don't want no lines.

    When data exists in the ORIGINAL, but not in review, I want to the inverse of the current value of the Budget column.

    Where the data exist in REVISED I want the REVISED value.

    I can see how I can do this, see below, but is there a more elegant solution?

    Code current to achieve this, is there a better way?

  • How can I compare the differences between two files After Effects?

    I have a major problem.  I was working on special effects for a film.  In After Effects, when I change siggificant, I often have to register under and create a new name so I can go back to the old work if necessary.  It comes in a case, I have come back from earlier works.  If I use these two files After Effects allows you to create multiple clips of effects.  And I do not remember just where you look at it, it is better.  Does anyone know a good way to compare the differences between the files?

    One thing to keep this conversation on the right way: I know that I did a stupid thing.  I've never done this before so can we please not spend a lot of time on how to avoid this problem and stick to how we solve this problem?

    If you encounter difficulties to identify differences in the old and new versions, you can use this procedure:

    To avoid confusion, I'll call your former company and your most recent compositions CompB comps.

    CompA drag "New Comp" icon in the project window.  This will create a new temporary layout that contains the nested CompA.

    Drag in your new COMP CompB temporary ensure it aligns image for image with CompA.

    Place the top layer (CompB) difference.

    Now, when you play through the comp, you'll see differences in color at a time where the comparison and CompB are not identical.

    Basically, I need to select the sculpture and do not want to spend time manually selecting due to its complexity. I need to separate the background and the sculpture for editing on their own layers.

    Thank you

  • How to tell the difference between two dates

    Hello:

    I have a question on how to get the difference in quantities for two dates in the replies and dashboard.

    This is the scenario. I have two guests date and three columns. The first column must be the sum of the amounts for the first quick date. The second column should be the sum of the amounts for the second fast date. And the third column is the difference between the first two columns.

    Basically, I'm trying to do something similar to a function of sum of two lines but trying to get the difference between the two rows. Any help to solve this problem would be appreciated.

    Use the COLUMN FILTERS level...

    the first column with the first variable of date quick presentation of the filter

    Similarly, the second column in the second variable of quick overview of date filter

    Kind regards
