Add days to date (integer format)

Hi all

I'm trying to add days to a date that is in numbers.

Suppose I have a date 20140331 and if I add + 1 to her I me 20140332. How can I get 20140401 in digital format using pl/sql query.

Also, I should be able to add any number of days existing dates to get the correct date. The example above is just a sample.

Thank you

Hello

Here is an example showing how easy it is to use the arithmetic of dates with DATEs:

CREATE TABLE table_x

(x_id PRIMARY KEY NUMBER

x_date DATE

);

ALTER SESSION SET NLS_DATE_FORMAT = 'YYYYMMDD ';

INSERT INTO table_x (x_id, x_date) VALUES (1, TO_DATE ('20140331', 'YYYYMMDD'));

INSERT INTO table_x (x_id, x_date) VALUES (2, SYSDATE);

SELECT x.*

x_date + 1 tomorrow

x_date + 10 AS ten_days

FROM table_x x

ORDER BY x_id;

Output:

X_ID X_DATE TOMORROW TEN_DAYS

---------- -------- -------- --------

1 20140331 20140401 20140410

2 20150219 20150220 20150301

Date arithmetic is also easy and intuitive, when using the DATEs as a number arithmetic is using numbers.

  • Add days to date

    Hello

    I'm sure it's something simple I'm missing :-)

    Here is the js that I use. 

    var dateToNumber is Date2Num (form1.page2.page2Date.rawValue, "MM/DD/YYYY");.

    var datePlusDays = dateToNumber + firstRowWeek.rawValue * 7;

    var boosterDate is Num2Date (datePlusDays, "MM/DD/YYYY");.

    Form1.Page2.invoiceTable.Row1.boosterDate1.RawValue = boosterDate;

    Everything I'm doing is take a date and add a few days according to what a person selects a list drop-down list.  The date that I use is of the

    $.rawValue = num2date (Date (), ' MM/DD/YYYY')

    I don't know why I can not work properly.  Any help would be appreciated.

    Justin

    This could be done in this way:

    $ = Num2Date(Date2Num(form1.page2.page2Date.formattedValue, "MM/DD/YYYY") + firstRowWeek * 7, "MM/DD/YYYY")

  • Add days to a Date/time stored

    Hello

    Here's what I'm trying to do.

    I am trying to add a field of records called #Warranty_Dump_Info.Reference # on a domain registration
    called #Warranty_Dump_Info.Purchase_Date # and get a later date representing the date of expiry of a factory warranty.

    #Warranty_Dump_Info.Reference # is a numeric value (30, 90, 180, etc.) that represents the number of days covered by the warranty and the #Warranty_Dump_Info.Purchase_Date # is the date/time value (example: 2009-01-01 00:00:00)

    I can get the date/time format (time deleted).
    with the help of < foutput > #dateformat(Warranty_Dump_Info.Purchase_Date, "mm-dd-yyy") # < / output >

    However, I can't seem to add the number of days value of #Warranty_Dump_Info.Reference # or to display
    in the right format of date (time stripped).

    I tried the time of #Warranty_Dump_Info.Purchase_Date # stripping and then saving them as a variable, then
    always using the Functionadds on the variable, but it fails to strip the time according to the results.

  • How can I add days to a Date value in a Script time?

    How can I add days to a Date value in a Script (XPATH) time?

    XPATH:

    Add Date:

    xs:dateTime($yourCurrentDateVar) + xs:dayTimeDuration($yourDuration)
    

    Difference in date:

    move "fn:days-from-duration(xs:dayTimeDuration(xs:date($yourCurrentDateVar) - xs:date($yourPrevDateVar)))" to $diff;
    

    You did not mention the version of the Framework, you can take advantage of the Business Service (BS) to perform Date calculations, for example, for FW2.2.x, you can use BS: C1-DateMath with such options as the 'Resistance' to add to the Date, "DIFF" for Date-Diff and FW4.x, you can use BS: F1-DateMath with options such as "F1AD" to add to the Date etc.

  • How to add days, hours, minutes and seconds to a date?

    Hello

    I have the following problem.

    For example, if

    Part 2, help information on the Format mask item property; you will need to make sure that you set the property correctly.

    Sorry, I had to drill two answers but my first attempt surpassed the eligible characters in an answer ;-)

    Format Mask property
    Description
    
    Specifies the display format and input accepted for data in text items.

    Usage Notes
    
    Valid format masks for character strings, numbers and dates are described in the following tables.
    Character Strings
    The following table describes valid format masks for character strings. 
    
    Element     Example     Description
    FM     FMXX99     Fill mode:  accept string as typed, do not right justify.  Allows end user input string to be shorter than the format mask.
    X     XXXX     Any alphabetic, numeric, or special character.  End user input string must be exact length specified by format mask.
    9     9999     Numeric characters only.  End user input string must be exact length specified by format mask.
    A     AAAA     Alphabetic characters only.  End user input string must be exact length specified by format mask.
    Character String Examples
    
    Format Mask     Description
    XXAA     Will accept: --ab, abcd, 11ab; will not accept: --11, ab11, or ab--(must use XX to accept hyphens and other special characters).
    XXXX     Will accept any combination of alphabetic, numeric, or special characters: --ab, abcd, 11ab, --11, ab11, or ab--.  Will accept 1234 or abcd; will not accept 123 or abc.  (To accept input string shorter than mask, use FMXXXX.)
    FMXX99     Will accept ab12, ab1, ab followed by two spaces; will not accept 12ab or abcd.  (To produce the Form Builder Version 3.0 Alpha datatype, use FMAAAAAA.)
    n     To embed additional characters such as a hyphen (-) or a comma (,), surround the character with double-quotes (").
    n     Embedded characters are separate from text item values and are not collated along with text item values, even when the end user enters them. 
    
    NUMBERS
    
    The following table describes valid format masks for numbers.
    
    Element     Example     Description
    9     9999     Number of nines determines display width.  Any leading zeros will be displayed as blanks.
    0     0999     Display leading zeros.
    0     9990     Display zero value as zero, not blank.
    $     $9999     Prefix value with dollar sign.
    B     B9999     Display zero value as blank, not "0".
    MI     9999MI     Display "-" after a negative value.
    PR     9999PR     Display a negative value in .
    comma     9,999     Display a comma in this position.  For correct behavior in multilingual applications, substitute G to return the appropriate group (thousands) separator.
    period     99.99     Display a decimal point in this position. For correct behavior in multilingual applications, substitute D to return the appropriate decimal separator.
    E     9.999EEEE     Display in scientific notation (format must contain exactly four "E"s).
    FM      FM999     Fill mode: accept string as typed, do not right justify.
    n     When you mask a number with nines (9), Form Builder adds a space in front of the number to accommodate the plus (+) or minus (-) sign.  However, since the plus sign is not displayed, it appears as if Form Builder adds a space in front of the number.  (The minus sign is displayed.)
    n     To embed additional characters such as a hyphen (-) or a comma (,), surround the character with double-quotes (").
    n     Embedded characters are separate from text item values and are not collated along with text item values, even when the end user enters them. 
    
    NUMBER Examples
    
    Format Mask     Description
    FM099"-"99"-"9999     Displays the social security number as formatted, including hyphens, even if end user enters only nine digits.To create a Social Security column, create an 11-character column, set to fixed length, with a format mask of 099"-"99"-"9999.  This mask will accommodate Social Security numbers that begin with zero, accepting 012-34-5678 or 012345678 (both stored as 012345678).
    99999PR     Accepts -123; reformats as <123>.
    999MI     Accepts -678; reformats as 678-.
    9.999EEEE     Displays as 1.00E+20.
    How Forms handles length mismatches
    
    If a runtime user enters a numeric string that exceeds the format mask specification, the value will be rejected.  For example:
    
    Format Mask     User enters     Result
    99.9     321.0     Invalid
    99.9     21.01     Invalid
    99.9     21.1     21.1
    99.9     01.1     1.1
    In contrast, if a numeric value fetched from the database exceeds the format mask specification for its display field, the value is displayed, but truncated, with rounding, to fit the mask.  (The item itself within the Forms application retains its full value.)  For example, if the database held the value 2.0666, and the format mask was 99.9, the value displayed to the user would be 2.1.  However, the value of the item within the form would be the full 2.0666. 
    
    Dates
    
    The following table describes valid format masks for dates.
    
    Element     Description
    YYYY or SYYYY     4-digit year; "S" prefixes "BC" date with "-".
    YYY or YY or Y     Last 3, 2, or 1 digits of year.
    Y,YYY     Year with comma in this position.
    BC or AD     BC/AD indicator.
    B.C. or A.D.     BD/AD indicator with periods.
    RR     Defaults to correct century.  Deduces the century from a date entered by comparing the 2 digit year entered with the year and century to which the computer's internal clock is set.   Years 00-49 will be given the 21st century (the year 2000), and years from 50-99 will be given the 20th century (the year 1900).
    MM     Month (01-12; JAN = 01).
    MONTH     Name of month, padded with blanks to length of 9 characters.
    MON     Name of month, 3-letter abbreviation.
    DDD     Day of year (1-366).
    DD     Day of month (1-31).
    D     Day of week (1-7; Sunday=1).
    DAY     Name of day, padded with blanks to length of 9 characters.
    DY     Name of day, 3-letter abbreviation.
    J     Julian day; the number of days since January 1, 4712 BC.
    AM or PM     Meridian indicator.
    A.M. or P.M.     Meridian indicator with periods.
    HH or HH12     Hour of day (1-12).
    HH24     Hour of day (0-23).
    MI     Minute (0-59).
    SS     Second (0-59).
    SSSSS     Seconds past midnight (0-86399).
    /. , .     Punctuation is reproduced in the result.
    "..."     Quoted string is reproduced in the result.
    FM     Fill mode: assumes implied characters such as O or space; displays significant characters left justified.  Allows end user input to be shorter than the format mask.  (Use in conjunction with FX to require specific delimiters.)
    FX     All date literals must match the format mask exactly, including delimiters.
    n     When you prefix a date mask with FX, the end user must enter the date exactly as you define the mask, including the specified delimiters:  
    
    Date Examples
    
    Format Mask     Description
    FXDD-MON-YY     Will accept 12-JAN-94, but will not accept 12.JAN.94 or 12/JAN/94 because the delimiters do not match the mask. Will not accept 12JAN94 because there are no delimiters.  Will accept 01-JAN-94 but will not accept 1-JAN-94.
    FMDD-MON-YY     Will accept 01-JAN-94.  Will also accept the entry of other delimiters, for example 01/JAN/94 and 01 JAN 94.  However, will not accept 01JAN94.  Will accept 1-JAN-94, converting it to 01-JAN-94.
    DD-MON-YY     Will accept 12.JAN.94, 12/JAN/94 or 12-JAN-94. Note: Any delimiter characters will be accepted, but if delimiters are omitted by the end user, this mask will interpret date characters as a delimiters.  Will accept 12-JAN94, (but will erroneously interpret as 12-JAN-04); but will not accept 12JAN94, because "AN" is not a valid month name.
    n     Use of a format mask only affects how the data looks.  Form Builder stores full precision, regardless of how the data is presented.
    n     Embedded characters are separate from text item values and are not collated along with text item values, even when the end user enters them.
    n     To embed additional characters such as a hyphen (-) or a comma (,), surround the character with double-quotes (").  Note, however, that double-quotes themselves cannot be used as a character.  In other words, trying to achieve output of DD"MM by specifying a mask of DD"""MM would not work.
    
    Format Mask     Description
    FMMONTH" "DD", "YYYY     Displays the text item data in the specified date format: JANUARY 12, 1994, including the appropriate blank spaces and comma.
    FMDD-MONTH-YYYY     Displays as 12-JANUARY-1994.
    DY-DDD-YYYY     Displays as WED-012-1994.  Note: for input validation including day of the week, a mask that allows specific determination of the day is required, such as this example or DY-DD-MM-YY.
    n     When you use day of the week formats, be sure that the data  includes day of the week information.  To avoid illogical masks, display also either the day of the year (1-366) or the month in some format. 
    
    Format Mask     Description
    DD-MONTH-YYYY     Displays as 12-JANUARY-1994.
    DY-DDD-YYYY     Displays as WED-012-1994.
    DY-DD-MON-YY     Displays as WED-12-JAN-94.  Be sure to include month.  Avoid masks such as DY-DD-YY, which could generate an error.
    NLS Format Masks
    
    The following table describes valid National Language Support (NLS) format masks.
    
    Element     Example     Description
    C     C999     Returns the international currency  symbol.
    L     L9999     Returns the local currency  symbol.
    D     99D99     Returns the decimal separator.
    G     9G999     Returns the group (thousands) separator.
    comma     9,999     Displays a comma in this position.
    period     9.999     Displays a decimal point in this position. Displays a decimal point in this position.
    NLS Format Mask Examples
    
    Format Mask     Description
    L99G999D99     Displays the local currency symbol, group, and decimal separators:  if NLS_LANG=American, this item displays as $1,600.00; if NLS_LANG=Norwegian, this item displays as Kr.1.600,00.
    C99G999D99     Displays the appropriate international currency symbol: if NLS_LANG=American, this item displays as USD1,600.00; if NLS_LANG=French, this item displays as FRF1.600,00.

  • Date/time format and different regions

    I'm developing an application in this case to the United States on the English LV2009 software.  This application will be installed in many parts of the world, and I just discovered a problem with the date and time that I try to understand.  A screenshot of the application running on a Chinese computer is attached.  At the top right there is a 'results save location' which has a month and year added file name.  I use the date/time format with modifiers for the name of the month and the year in 4 digits (%B %Y).  On my PC, it displays in July 2010, but on Chinese computer it 7 01.  In addition, the reason that it says wrong serial number is that I compare the SN 2-digit year, and it seems to enter it correctly.

    On my PC, I tried to change my date settings in Windows and it doesn't seem to affect the production, as it does on Chinese computer.  I know there is a UTC Boolean selector which can be activated.  That will make a difference in the way that the date is displayed by this function?

    This is one of the few issues I encountered when developing a program for several regions, but it is currently the only one, I have not yet solved.

    I would expect month name to be specific langauge.

    For example, the word April in French is April and is abbreviated Apr. I would use a number instead of the name.

    The thai calendar + 543 years compared to the Western calendar, so a PC Thai could show a specific locale of 2553-07-13 date. Your computer may display 13/07/2010. I'm sure that the year of the Chinese calendar is different from that of the Western calendar.

    Using UTC should force LabVIEW to use the Gregorian calendar, based on the ISO-8601standard.

    Because your users work with technology and would probably recognize a Gregorian day/month/year combo I would stick with % Y_ m_ % d. % and UTC = TRUE.

    I contributed a VI to the community OR that you could use if you wish. It has many options and is based on ISO-8601

  • changing dynamic date/time format

    How can I set a Date/time format) of a textbox (behave like a phone number format, where the user enters only numbers, but it shows another way of my choice.)

    Download the new Date object
    var a = event.target.value;

    Kai var = util.scand ("YYYYMMDD", a);

    xDate var = util.printd ("yyyy/mm/dd", anyway);

    Event.Target.Value = xDate;

    It does not work.

    Text type fields have scripts that control the key sequence, validation and formatting. You only play with the formatting.

    You could create a script to strike to allow the entry of the date with or without the "/" but you then have to write a script of presentation and validation. Posting date is not just month 1-12 and day 1-31, because some months have 28, 29, 30 or 31 days depending on the month and year combinations.

  • Failed to get the disk partition information when you add the new data store

    Hello

    Update my ESX to version 4 Update 1 (4.0.0, 256968). Now, I'm trying to add a new data store to a cluster in vCenter and receive the following error message when I will review the current structure of the disc "error when configuring the host: failed to get the disk partition information. When I click back, then next, there's no error message but in the formatting window, I get the error "Object reference" not set to an instance of an object.

    I see this question has been asked before, but I can't seem to find an appropriate response. Anyone? The interface using CLI instead of vCenter isn't an option (alignment VMFS, workload and so on)

    I use Dell R900 with an EMC Symmetrix VMax SAN

    The size of the LUN I want to add is 741 GB

    Concerning

    Marius Aulie

    If you have a virtual machine for Windows test, you could do the following, to ensure that the logic unit number has a clean partition table:

    -set the LUN as a GROSS physical to virtual machine device

    -Run diskpart, select the drive and run the CLEAN command

    -detach the LUN to the virtual machine

    -try to create the data on the LUN VMFS store

    The size of the block of the data store where the VM test can be a problem with the above. Due to the size of the LUN, the size of the block of the data store must be at least 4 MB. Attach the LUN to a physical test system could be an alternative.

    I would be very grateful for any input or advice help...

    Well Yes...

    ASPvb script

    Thanks for the control of Mr Adobe - it seems that someone in the development of the production misnamed the file source DateTime in the Formats.xml file.

    The formats.xml file is a reference to the source file as DateTime Date/time NOT

    Remove the slash in the file reference name and everything works fine...

    See the path of file-
    C:\Program Files\Adobe\Adobe Dreamweaver CS3\configuration\ServerFormats\ASP_Vbs\Formats.xml

    Now to return to developing countries... What Date/time/Frustration!

  • Re: How to restore data after format disk?

    Hi, people

    I need your help to restore some important data which disappeared after formatting the hard drive.
    I have not any backup that was my mistake.
    Everyone's help is appreciated.

    Thank you all.

    Hi mate

    I don t think you will be able to do.
    Usually, data are lost after you have formatted the HARD drive.
    Of course, there are some different applications that could help recover some data for example. Data Recovery Wizard, but it is not cheap software.

    But I found this:
