Default Date Format in Oracle 9i

What is the default date given by oracle 9i when the column is specified as NULL for the date column ?
Just like in SQL Server 2000 when date is given as NULL, it will give date as
'1900-01-01 00:00:00' in that column. What is it in Oracle 9i
Thanx in advance!

It will be a NULL, unless you specify a DEFAULT for the column:-
<code>
SQL> create table t ( x int, y date );
Table created.
SQL> insert into t ( x ) values ( 1 );
1 row created.
SQL> select * from t;
X Y
1
SQL> alter table t modify ( y date default sysdate );
Table altered.
SQL> insert into t ( x ) values ( 1 );
1 row created.
SQL> select * from t;
X Y
1
1 21-JUL-05
</code>

Default date format in oracle

Hi
What is the default format of date in oracle?
When I rum the following query
select * from emp where hiredate='03-december-1981' ...
It is returning two records.
How is it possible?

For input and output of dates, the standard Oracle date format is DD-MON-YY

Although it's there in the documentation, I find it misleading, as many times, the default nls_date_format has been changed to something else, either by the dba's, or by a front end application or whatever.
It is ALWAYS safest to use to_date and to_char when working with strings-that-you-want-as-dates or dates-that-you-want-as-strings respectively.
Any time you store a date in the database, store it in DATE format - this gives oracle valuable information (eg. that it's a date and not just a string) which allows it to make decisions correctly when comparing them. Eg. '22/01/2009' is earlier than '14/02/2009' if the database knows it is a date, but is later if all the database sees is a string (14 being less than 22, of course).
Anything that is already in date format, you do not need to change if you're using it in calculations (eg. select date_col_1 - date_col_2 from my_table , or sysdate) but any time you interact with the database to input a date or extract a date, you need to use to_date or to_char. (it's less important with the latter, if you don't really care how the date is displayed). Do not ever to_date() something that is already a date - you force implicit conversions of the date and that is a) pointless and b) could cause bugs in your code.
Even the experts sometimes get caught out with dates, when they rely on implicit conversions!

How to update the default date format in OBIEE 11G.

Hi All,
How to change the default date format in OBIEE 11g from the MM/DD to DD/MM. Could anyone please help me out ASAP?
Thanks,
Arpan

Hi Arpan
OBIEE 11g is having " localedefinitions.xml " file at this Location C:\Oracle\Middleware\Oracle_BI1\bifoundation\web\display
in my case i installed at C:\Oracle\MIddleware.
so
1- Stop BI Server from EM
2- Navigate to this Location C:\Oracle\Middleware\Oracle_BI1\bifoundation\web\display. in your case oracle home will be different
3- take a backup of this file localedefinitions.xml "
4- modify it and save
5- bring BI Server up.

Date format in Oracle 10g XE

I'm using Oracle 10g XE on Windows Vista and I'm curious as to what determines the date format.
According to the globalization section in the Oracle installation guide the NLS_DATE format is dependent on the NLS_LANGUAGE setting. In my database the NLS_LANGUAGE is American, the NLS_TERITORY is America and all other NLS_* parameters are blank (default).
From that I would expect the default date format to be mon-dd-yyyy.
However when I run SELECT sysdate FROM dual the date is reported as dd/mm/yyyy and this was the default format when I used SQL Developer and when I used the command line SQL*Plus. Obviously something else is determining the date format, but what?

Your settings are dependent on NLS_LANG on the client.
They are derived from (assuming Windows) the regional settings of the O/S.
This means in Western Europe the default 'American_America.WE8MSWIN1252'.
This makes the default NLS_DATE_FORMAT dd-mm-yy.
You can override this in the registry, or set up an after logon trigger.

Configuring date format in Oracle 8.1.7

I have just unloaded records from tables into an sql script file with insert statements. However, the date format for the records that I have unloaded is MM/DD/YYYY. When I try to run this sql script, oracle gives an error, saying it's not a valid month.
Oracle date format is DD-MMM-YY. How can I change the date format in oracle, so that I could insert these records in?

If your script does not have explicit TO_DATE conversions (which it should, by the way), like:
insert into t values (to_date('11/21/2002', 'mm/dd/yyyy'));then you can set the default date format to match the format in your script. So, if your script looks like:
insert into t values ('11/21/2002');then:
alter session set nls_date_format = 'mm/dd/yyyy';prior to running the script.

Date Formats in Oracle Applications Forms and Oracle Self Service

Can someone tell me what determines the Date format that appears on Oracle Applications Forms and Oracle Self Service ?
*1.* In Oracle HRMS,all dates i see on the Forms are of the Format "MM/DD/YYYY" but my NLS Parameters are not in this format .I'm giving the results for the NLS parameters below.I thought the date formats are determined by the NLS format.Is there something else that determines the date format appearing on Oracle Applications Forms ?
NLS_DATABASE_PARAMETERS
NLS_DATE_FORMAT     :DD-MON-RR
NLS_DATE_LANGUAGE     :AMERICAN
NLS_LANGUAGE     :AMERICAN
NLS_TERRITORY     :AMERICA
NLS_INSTANCE_PARAMETERS
NLS_DATE_FORMAT     :DD-MON-RR
NLS_DATE_LANGUAGE     :
NLS_LANGUAGE     :american
NLS_TERRITORY     :america
NLS_SESSION_PARAMETERS
NLS_DATE_FORMAT     :DD-MON-RR
NLS_DATE_LANGUAGE     :
NLS_LANGUAGE     :american
NLS_TERRITORY     :america
*2* What about the profile option : ICX_DATE_FORMAT_MASK ? Does it determine the Date Format for Self Service alone or does it impact the date format appearing on Oracle Applications Forms and the actual database also ?
*3* If I use a to_date function in ,say, a pl/sql function that i code for some custom requirements,what will be the output of the date format ? Does it take the format given in NLS paramaters or is it determined by anything else?
Thanks in advance...

Hi,
Thanks for your reply ,but I'm still confused ..
Here are the profile options I'm seeing for one of my instance :
ICX: Date format mask - 12/31/1999
ICX: Date language - American English
ICX: Language - American English
ICX: NLS Sort - BINARY
ICX: Territory - United States
ICX: Numeric characters - NULL
NLS parameters are given in my original email.
In Self Service applications(OAF) ,the date format is appearing in "mm/dd/yyyy" format but when i login to Forms based applications ,I see the date format as "dd-mon-yyyy".What determines this date format ?
How can i make the date format to always return one format everywhere ,be it Self Service (OAF) or Oracle Forms ?
I'm getting date format related errors for my code because of default date formats changing intermittently when i log into Self Service.I want to know if there is anyway to prevent this from happening?
Thanks in advance.

Regarding TO_DATE function and Default Date Format DD-MON-YY

I am using oracle 10.2 version. As far as my knowledge default date format is 'DD-MON-YY'. I want to know that why first query is not giving result.
SQL> select sysdate from dual
2 where sysdate = to_date('06-JUL-11','DD-MON-YY');
no rows selected
SQL> select sysdate from dual
2 where to_date(to_char(sysdate),'DD-MON-YY') = to_date('06-JUL-11','DD-MON-YY');
SYSDATE
06-JUL-11
Thanks,
Rohit

A date in Oracle always contains hours, minutes and seconds. These values can optionally all evaluate to zeroes, at midnight.
TO_DATE('06-JUL-11','DD-MON-YY') means midnight of the sixth of july 2011.
So
sysdate = to_date('06-JUL-11','DD-MON-YY') only at midnight of the sixth of july 2011...
While during the day, after midnight,
trunc(sysdate) = to_date('06-JUL-11','DD-MON-YY')and
sysdate > to_date('06-JUL-11','DD-MON-YY')Max

Is it possible to change the Database default date format 'dd/mm/yy'

I'm inserting a date with the format 'dd-mon-yy' in a column, it gives the error:- " a non-numeric character was found where a numeric was expected ". I also tried the TO_DATE function but not successful.
I want to change the Database default Date format 'dd/mm/yy' to 'dd-mon-yy'. Is it possible?
version is (Oracle Server 7.3.2.0). I checked it on version ( Oracle Server 7.3.4.0) with format of 'dd-mon-yy'.
May I keep the both formats at a time?
Thanks for solution(s),
Tariq.

you can try with:
ALTER SESSION
SET NLS_DATE_FORMAT = 'dd-mon-yy';

Set Default Date Format in 4.2 jQuery Mobile Smartphone

Hi guys,
on "normal" Desktop interfaces you can set a default date format in the Globalization settings. Currently I'm working on a JQM app, and I noticed, that the same settings I have for date format in other apps, don't take affect.
I now read in the 4.2 release notes, that somehow this issue was a bit buggy. Is this fixed? I would like to set a german date format like "DD.MM.YYYY"; (as it's working in desktop apps). How can I do it? In global settings this entry gets saved.
But whenever I want to set an individual date-picker-item to that format, it changes back to "YYYY-MM-DD" after saving. And I don't really want to get into writing a conversion function in the dml-processing now.
Thanks for any hints, best regards,
tobi

Hi Tobi,
the "Date Picker (HTML5)" item type maps to the HTML5 input type="date", which requires that the internal format of the date value always has to be YYYY-MM-DD, but it's up to the browser to actually display the date in the format of the local operating system setting. The browser of iOS for example shows the date in the format of my local language/country setting.
See also http://stackoverflow.com/questions/7372038/is-there-any-way-to-change-input-type-date-format
To make a long story short, it's not possible to specify the display format for those date pickers, because it's not supported by the HTML5 spec.

Hi It depends upon the NLS_DATE_FORMAT parameter value
it may be different
for me its
SQL> SELECT value FROM v$nls_parameters WHERE parameter ='NLS_DATE_FORMAT';
VALUE
DD-MON-RRDD-MON-YYYY is the default date format given by oralce if you want to change it use

How to change default Date format in BO 6.5 SP4

A problem with date display has been reported to me by one of our users - in BO 6.5 - since installing SP4.
The default date format is now MM/DD/YYYY
I have tried to recreate this on my PC and have been able to confirm that this is the case.
Most of our PC's will have two versions of Business Objects on them - for 5.1.6 and for 6.5 - that is the case for my PC.
If I create a new BO document based on a spreadsheet with three entries in the spreadsheet as follows:-
20/01/2009 20-Jan-2009 20th January 2009
This displays in BO 6.5 as
1/20/2009 1/20/2009 20th January 2009
My PC regional setting is UK and the time displays DD/MM/YYYY
Can you advise how to correct this problem please.

Hi Sebastien
Thank you for your response.
I haven't checked Dimension in universe because this is happening even when datasource is an Excel spreadheet - as per details in previous post.
I have looked for *.sbo files and found one for ODBC.sbo in the Version 5 folders on PC - with date format details in it which I've changed - that doesn't make any difference.
Any other ideas?

Ex.. If the user has set the default date format in SU01 as ' YYYY-MM-DD' , in report also, date should appear as '2009-12-24'.
Is there any code or Function Module to change the date format in report as in the default Date format?
Can u help me in this?

Default Date Format in ADF 11g RC

Dear All,
I am searching for a possibility to set a default date format pattern ("yyyy-MMM-dd") in an ADF 11g RC application.
I know that I can set this format in every entity/view object's attributes. But I am looking for a central way.
I already tried to override the javax.faces.convert.DateTimeConverter and configured it in the faces-config.xml.
But without success.
Any ideas?
Thanks!
Richard

Hi,
in another post of yours I pointed you to the trinidad-config.xml file - so you may want to have a look there. Also maybe property sets can give you a helping hand
