Why there is no datatype which only stores date (without time part)

Hi All,
Is there any specific reason for not having a data type which only stores date (without time part) in ORACLE - I am asking this because DATE (without time) is a very frequently used data type in any application.
Thanks.

Then why ORACLE is allowing to have scale and precision in a NUMBER data type. If I want to store an integer there is no harm in storin it just as NUMBER. But I habe option to give something like NUMBER(10). But in DATE, the time part is mandatory.a) because there's no need for seperate DATE and DATETIME datatatypes, and b) the time part is not 'mandatory'.
SQL> create table mytable (x date);
Table created.
SQL> insert into mytable (x) values (to_date('01/01/1980','DD/MM/YYYY'));
1 row created.
SQL>The DATE datatype contains the Time as well, to make it flexible... a single datatype that can do both things without the need for any conversion between datatypes (either explicitly or implicitly).
Yes, many application need to have fields on the screen that just show a date, such as a date of birth as you say, but that's simply a display issue, and any application interface will allow for a date format to be specified for displaying the data from the database, so in terms of such "Date only" dates, you would simply use a format mask that ignores the time portion.
There's absolutely no issue with the fact that it's just a single datatype... it causes no problems... it's perfectly flexible at being used for just dates or for dates and times... so why such a concern?

  • How to get only the date without the time in the footer of a printout?

    Is there a way to get only the date without the time in the footer of a printout?

    As far as I can tell, there's no built-in option to get the date printed without the time. It's hardcoded in a C++ file.
    As a workaround, you can enter custom text for the footer, but it would need to be updated every time the date changed. I can think of a couple ways to automate that:
    * An add-on (but I'm not aware of any add-on for this)
    * External process to push a new date into prefs.js, a settings file that stores your header/footer preferences, among others (but Firefox should be closed when you update this file, and it will be read when you restart)
    Not easy enough, I know.

  • Why there is no uttorent in app store.

    Why there is no utorrent in the app store?

    Might be because a torrent site would not meet the stringent requirements and because the app store is in business to sell apps vs. a torrent site which makes things available for free (even though they may cost money elsewhere).

  • Why can't I choose WHICH music store to shop from?

    Is there any way of changing between music stores, i.e. why can't I go from U.K to Sweden to France to wherever? If I want books from all over?
    Is it just me that's annoyed by this, I'd like to be able to switch stores like I do in real life?
    If any of you wiz's out there have got any hints, I'd be really grateful!

    Hi Terence, and thanks for a really quick answer!
    I just meant that I want to be able to find audiobooks from several stores, but when I search "my" store I only get English versions, or none. I seem to be on the UK store but I'd really like to be able to go between stores like you go between countries.. Surely my credit card(s) can't determine this? I thought it was a signing up thing? But maybe there's no way of changing stores, yet? can I hav several iTunes on my computer?
    I really don't want to be troublesome or to have any trouble, i just would really like this thing to be properly global...

  • Internal Reconciliation - which field stores date of Reconciliation

    Hi Experts,
    I am looking to produce a rerport with shows payment on account and invoices and the date that they were Internally Reconciled against each other.  Is this date stored in any table?
    I have checked the ORCT table and on Internally Reconciling a Payment On Account to and Invoice the following fields are updated:
    OpenBal
    OpenBalSc
    However, I cannot see that the date of the reconciliation is stored.  Is it marked elsewhere, perhaps in another table?
    Thanks
    Greig

    Hi Rohan,
    Thanks for the information.  However, I'm still struggling to create a query which shows what date an invoice was internally reconciled.
    If I take the OINV table, the invoice number is stored in DocEntry and DocNum.
    OITR is the Internal Reconciliation header table which is linked to the ITR1 detail table as follows:
    OITR.ReconNum = ITR1.ReconNum
    The ITR1 detail does not seem to link to the OINV table... there is a ITR1.TransId field but this does not link to OINV.
    In summary, my question is: how can I link ITR1 to OINV?
    Thanks

  • Is there a file in which OSX stores the home directory path, where to find it and how to edit it in Windows 7?

    Hi everyone,
    I have a SSD with the System and Apps on it, and another HDD containing the home directory.
    I made the mistake to rename the Volume the home directory is on whilst being logged in, the system reacted accordingly and prompted some Password requests,
    and I then tried to choose the newly named Volume in the Advanced options dialogue in Users & Groups (example seen below).
    I tried to change the name back to what it was in the hope of it all being back to normal again, but instead it's completely messed up now and I cannot login anymore (prompt: "You are unable to log in to the user account "xxxx" at this time. Logging in to the account failed because an error occurred")
    All I can do now is boot my Windows 7 and try to fix this from there, I can read/write the OSX Volumes thanks to MacDrive.
    So now the big question is:
    IS THERE A FILE containing the path to the home directory (red arrow)?
    IF SO, WHERE can I find it?
    And is there a way to edit it in Windows?
    My guess is that if I rename the Volume, AND change this path to something identical again, it might solve the issue.
    Thanks!

  • Why does CC update .png files only some of the time?

    I am creating some lower thirds from a template in PS, saving them as .png files and bringing them into the project. When I get updates from our clients, I will make those changes in the .psd, and save over the original .png file. Sometimes CC will update that file in the project without having to re-import and everything is fine. It isnt a huge hassle to just replace the file but Id like to know why it only works some of the time.

    The script only outputs the names of the services that have deployments, because the get-azuredeployment cmdlet encounter error and didn't pass the result to select cmdlet, please try the script below:

  • How can I utilize text variable in my book which only uses data merge on the first chapter?

    Hey ladies and gents, I'm trying to automate a process here and running into trouble. I have the first chapter of a book with several data merge fields (legal documents etc), and want the later chapters to pick up from what I have already merged via text variables or SOMETHING. From what I've tried, the options available to me are limited and buggy.
    Using the running header with character styles almost worked, but it removes all visual tracking in text around it (I assume this is a bug) and it only works for the first/last instance of the style. I need something that will fill in all instances.
    Here is an example of what I'm doing. In the ch1 document of my book I data merge the Name, Age and Occupation of a person. In chapter two I want to have a variable that takes the name that was merged in ch1. Any ideas? Doesn't seem possible!

    I need some solution that references live text, specifically different fields that have been data merged. This solution needs to work between documents, so your cross-reference suggestion was in the right direction. If I data merge 'Plan Name' from a CSV file into my first document and mark it with something (character style, paragraph style, text anchor etc), I want to have places in my other documents that pull that exact text from the first.
    If document 1 says 'the plan is XXXX', document 2 will copy that name, i.e. 'According to plan XXXX'. Whatever solution this is it's what I'm looking for.

  • Why do I receive messages with only a date, no subject, no from, no body, etc.?

    at varying times I receive messages with a blank subject, no entry in [from, to] no body, but a date in 1969.
    Any ideas why I receive these?

    Thank you for your help.
    I tried emptying the inbox, deleting the 2 files, and restarting TB.
    I did the same for Sent and Trash.
    I also deleted all .msf files for all inbox sub-folders and for all folders and sub-folders under "My Mail".
    the problem persists.
    My inbox has many sub-folders and sub-sub-folders should those be moved to My Mail?
    Another problem I am having. I do not know if it is related.
    I have a stack of filters that move incoming mail into folders. The stack ends with 2 filters.
    (1) a filter that checks whether FROM is from someone in my mail lists. It then moves the message into a folder called "Known Sender".
    (2) a psuedo-ELSE filter that check whether the subject contains a very improbable string. It put the message in a folder called ") Suspicious".
    Sometimes I still end up with folders in Inbox that clearly should be in the two folders, "Known Sender" or ") Suspicious".

  • How to do import of only table data without procedures and synonyms

    Hello All,
    I want to import only the tables of one database to a new database. I did a table level export of one schema. But along with it the stored procedures,synonyms, views etc are exported. Is there any way to stop them. Or is it possible to import only the tables from the dump created?
    Regards

    Hi Maran,
    Thanks for the feedback. I think I didnot specify the parafile with the table list while exporting. I am redoing it now. I shall update this post within 20 minutes.

  • HT1766 Is there way of accessing your back up data without the use of an i-phone?

    Is there a way of accessing your back up data from the computor without the use of an i-phone?

    If it wasnt activated prior icloud wont help now. Did you ever use the save and print option to "send it itunes"?  I did that all the time prior to icloud to back up my docs. Then you can "copy from itunes" in the new document dialog.
    I still recommend doing the export to iTunes to create a local back up copy on ocassion.
    For future reference, To activate icloud for documents, go into the main settings app, tap icloud, then documents and data, and turn it on. Then go to the app (maybe numbers) further down the main settings list, tap it and turn on "use icloud".

  • Is there any chance that ORacle RDBMS persuades ODBC to consider Oracle Date type as Date without time

    Hello,
    I have complain from SPSS end user reaching Oracle through ODBC interface that Oracle date fields are considered as datetime fields in SPSS.
    It is the whish that SPSS would consider Oracle date field right from the beginning as date field without the need to reformat field...
    In SPSS dictionary field is described as DATETIME20 after query from the database.
    Any idea is apreciated,

    I just double check and didn't see this option anywhere. You can however copy/paste text on a BlackBerry. I believe the only way would be to copy it in your email client and have the BlackBerry synchronize with it

  • Displaying metadata, how to display ONLY the Date

    I would like to display the Date below each image in Aperture 3. When I select "Date" in the Browser & Viewer Metadata window, the result is a very long string with the Date, the Time and the Time Zone. meaning that most of the time I see nothing because the string is much too long to be displayed...
    How to display ONLY the Date ?

    I said at the top of my first response above: +Afaik, there is no way within Aperture to change the date format of the date metadata overlay.+
    Send Aperture feedback to Apple via "Aperture→Provide Aperture Feedback"
    In the past I used Expression Media and the config for displaying such info was better.
    Aperture has a strange interface for it (and for other parameters), it does not behave at all like an Apple software (for the GUI), probably an external development team... but I agree it is more complex than iPhoto.
    Aperture is 10x more complex than iPhoto.
    If you want to see a rigid, boxed, "engineer"-style image database interface, take a look at Lightroom 3. It's a great program -- but it's a very different concept of information presentation and interaction.
    Thanks again.
