FOR DATE DATATYPE

Good Morning Everyone,
We only knew NVL for Number. Now, we would like to return all dates.
SELECT C.START_DATE, C.END_DATE, C.CREATE_DT, C.MODIFIED_DT
FROM CLASSES C
WHERE C.C_ID = 31
30-JUN-00 22-DEC-07 30-FEB-10
1 row selected.
Thanks in advance,

S!GNot not exactly sure what your question is......"Now, we would like to return all dates." Ok, take out the where clause and all the dates for the table should return for the columns you listed.

I also tried to declare variable of date from sqlplus but it seems sqlplus doesn't have any support for date datatype var declaration as bind variable.
Thanks

I think in this case you would have to take an approach like this:
alter session set set create_stored_outlines=true;
run your sql-statement (with a date bind variable), using anonymous plsql block.
alter session set create_stored_outlines=false;
Not sure though. It's been a while since I played around with outlines.

Functions for date datatype

Dear ALL...
Someone know some function for query months, years, days from date columns....???
Example for MSSQL...select datepart(date collumn) from table....select month(date column) from table....etc
I´m studing Oracle alone to get a OCP (OCA first)......the bad thing...I Work with the MSSQL.. (to me, Oracle is the best RDBMS)...

Hi Daniel,
Well I saw that you come from Brazil and as you are studying Oracle by yourself, take a look on my blog http://mportes.blogspot.com - There you're going to find a lot of technical stuff in Portuguese. For intance you might interest on this
http://mportes.blogspot.com/2005/11/trabalhando-com-intervalos-de-datas.html
About your question, you can start with
SQL> select to_char(sysdate, 'Mon') from dual;
TO_
May
1 row selected.
SQL> select to_char(sysdate, 'Month') from dual;
TO_CHAR(S
May
1 row selected.
SQL> select to_char(sysdate, 'Month', 'nls_date_language=portuguese') from dual;
TO_CHAR(S
Maio
1 row selected.To find more information, I suggest you stop by
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14200/functions180.htm#SQLRF06129
and try out http://tahiti.oracle.com there you will find all docs from Oracle (free).

Need to raise an error if Users puts wrong value for date datatype in Forms

Hi all,
I've created a new form using Template.fmb in forms 10g having some text item with data type as DATE.
and now i wanted to raise an error if users inputs any wrong data rather than DATE format.
Please help me if anyone knows how to do this...

As of now i am not looking for validation, i know the validation will automatically done but if you see by default it will not raise any error message if you fill any wrong value in text item with date data type. It will freeze the cursor to the text item.That is NOT the default. The default is to issue various FRM-nnnnn messages, between 50002 and 50026. From notes I have:
-- 50002: Month must be between 1 and 12.
-- 50003: Year must be 00-99 or 1000-4712
-- 50004: Day must be between 1 and last of month.
-- 50012: Date must be entered in a format like <fxMMDDRR>
-- 50017,18,19: Hour,Min,Sec must be between 0 and 23,59,59.
-- 50025: Date/time must be entered in a format like <xxyytttt>
-- 50026: same as 50012 and 50025 with <yyyy> year.
And from my old, dusty copy of the Oracle Developer/2000 "Messages and Codes Manual", those messages have an error level = 15.
If you are not seeing those messages, then you have done one of two things:
1. Set your System.Message_Level to a value of 15 or higher. You should NEVER set it above zero, since all that does is hides error messages like these. If you want to bypass or prevent an error message, it should be handled in the Re: FRM-40735:Pre_Insert trigger raised unhandled exception ORA-20011.
2. You have some bad code in an On-Error trigger that fails to handle errors correctly.

Database Variant to Data.vi not working for the Date datatype with LV 8.2?

I'm moving a large body of LV database code from LV 7.1 to 8.2 and find that the Database Variant to Data.vi is not working correctly when used with the Date datatype. It works fine with 8.0, and the common Variant to Data works also. Am I missing something? Thanks in advance for any assistance. Wes

Thanks for the prompt reply Crystal,
The data is stored in an Oracle database using the DATE type. I'm querying many rows along with other columns and converting each of the values as necessary for each column with the 'Database Variant to Data' vi. Only conversion to Timestamp is no longer working as of version 8.2. I recognize that plain Variant to Data works but I have many (100's) of VIs to change if that is the only solution (not the end of the world). Most often the dates are originally generated in the database using PL/SQL procedures calling SYSDATE which look like: 5/1/2006 11:56:26 AM (in TOAD anyway) which I then need to read into LV as type Timestamp.
Regards, Wes.

Problem while inserting data for some datatypes in Oracle 10g

Hi
I was trying to insert data in database for all the data types defined in Oracle 10g.
I was successful in maximum cases.
I was not able to insert data for following datatypes:
1 Long varraw
2 string
3 varraw
4 varnum
5 charz
6 unsigned int
7 native double
8 native float
Please put some light on it.
Thanks,
Gyanendra

Hi Subin,
You can try couple of things.
If your data is less than 32767, you can pass it to stored procedure and change it to clob type like
PROCEDURE CLOBQUERY
Param IN CLOB,
and you can call Procedure
EXECUTE CLOBQUERY '[Param.1]'
If your data is around than 1000000(32767*32), you can break the data in length of 32767 and pass it to param 1 to 32 like
EXECUTE CLOBQUERY '[Param.1][Param.2][Param.3]..[Param.32]'
Finally you can try to update jdbc drive.

Using number datatype for date column

Hi
Is there a side effect for using "number" datatype for "date" column?
If so, what is the disadvantage?
Many thanks

Oracle provides date arithmetic and a number of functions for manipulating DATEs. None of them work with numbers.
For example,
SELECT    TRUNC (order_date, 'MONTH')     AS order_month
,       AVG (ship_date - order_date)     AS avg_delay
FROM       orders
GROUP BY TRUNC (order_date, 'MONTH')
;order_month involves a DATE function; it's pretty easy to find the month that conatins order_date.
avg_delay involves date arithmetic. It's extrememly easy to find how much the time passed between order_date and ship_date.
Depending on how you code dates as numbers, doing either one of the above may be just as easy, but doing the other will be very difficult. You'll waste a lot of effort converting the NUMBERs to real DATEs whenever you need to manipulate them.
Validation can be very difficult for NUMBERs, also.
Watch this forum. It's a rare day when there's not some question about how to get around a problem caused by storing dates in a NUMBER (or VARCHAR2) column. Don't add to that. Always use DATE columns for dates.

Unable to insert date and time when using date datatype

Hi
I am hitting a bit of a problem when using the date datatype. When trying to save a row to the table where the field it throws an error ora 01830 and complains about converting the date format picture ends...etc. Now when I do the insert, I use the to_date function with the format of "dd-mon-yyyy hh24:mi:ss". Of course, when I remove the time element, everything is perfect.
Checking sysdate, I noticed that the time element wasn't be displayed, and I used alter session set nls_date_format to set the date and time I want to save to the table, which worked!
Then based on advice in a previous thread to permanently fix the problem, I used alter system set nls_date_format ="dd-mon-yyyy hh24:mi:ss" scope=spfile; This showed that it was altered, and I can see the setting in the em. In sqlplus, I shutdown the database, and restarted with startup mount; alter database open; and then selecting sysdate, it still shows the date as dd-mon-yy, and still no time! Checking the em, and looking up the nls_date_format the setting is still shown as "dd-mon-yyyy hh24:mi:ss".
So, my question is this - what am I doing wrong? Why can't save date and time using date in Oracle 11g?????
Thanks

ThanksYou most certainly can save the time. A DATE column, by definition stores date and time. What you describe is a presentation problem, and setting nls_date_format at the system as an init parm is the weakest of all settings as it is overridden by several other locations.
without seeing the exact sql that produced the error (not just your description of what you think you were doing) it is impossible to say for sure.
However, I'd suggest you read http://edstevensdba.wordpress.com/2011/04/07/nls_date_format/

How to get a time part from Date datatype

Hi,
I would like to know how to extract the timestamp alone from DATE datatype? If my input is '27-SEP-2011 23:59:00' I need the output as 23:59:00. I am surprised to see that there are no in-built functions for this or may be I am wrong. Basically I need to remove the date part from DATE data type and get the time.Please assist.
-Thanks

There is a built-in function, TO_CHAR:
TO_CHAR (dt_col, 'HH24:MI:SS')Depending on how you plan to use the time, TRUNC is another handy built-in function:
dt_col - TRUNC (dt_col)is a NUMBER (not less than 0, but less than 1) which is suitable for many tasks, such as finding the average time.
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.

How to compare the date value with the date datatype column?

Hi,
I am executed a query to get output for the particular date in two different database.
I got output in one db environment, but in the another environment i didnt get the output.
APP_DECISION_DATE column contains date datatype
ex:
SQL> select DECISIONED_STAGE_ID,DECISIONED_STAGE_USER_ID from naap10_application where APP_DECISION_DATE = TO_DATE('23-JAN-07',
'DD-MON-YY'); 2
DECISIONED_STAGE_ID DECISIONED_STAG
2006060106 SYSTEM
DATABASE - II
SQL> select DECISIONED_STAGE_ID,DECISIONED_STAGE_USER_ID from naap10_application where APP_DECISION_DATE=
TO_DATE('31-JAN-2007','DD-MON-RRRR') and application_id=2007010028552;
no rows selected
in the same db i got the output while i used the TO_DATE(APP_DECISION_DATE)
SQL> select DECISIONED_STAGE_ID,DECISIONED_STAGE_USER_ID from naap10_application where TO_DATE(APP_DECISION_DATE)=
TO_DATE('31-JAN-2007','DD-MON-YYYY') and application_id=2007010028552; 2
DECISIONED_STAGE_ID DECISIONED_STAG
2006060113 SYSTEM
is it necessary to use TO_DATE function while i am using the data datatype column in the WHERE CLAUSE?
Thanks in advance.
siva

Sorry & thanks sathish,
Now i got the result.
SQL> select DECISIONED_STAGE_ID,DECISIONED_STAGE_USER_ID from naap10_application where APP_DECISION_DATE BETWEEN TO_DATE ('31.01.2007 00:00:00', 'DD.MM.YYYY HH24:MI:SS') AND TO_DATE ('31.01.2007 23:59:59', 'DD.MM.YYYY HH24:MI:SS')
2 and application_id=2007010028552;
DECISIONED_STAGE_ID DECISIONED_STAG
2006060113 SYSTEM
================================
But one doubt,
When i created the column with the date datatype how it gets the time value,
And in one environment db i got the result but in another environment i dont get,
Shall i want to change any session status of date?

Problem in converting character into date datatype

Hi Experts,
I am developing an oracle function in which I am passing an input in varchar2 and I want the return that varchar value in date datatype.
We are using to_date(to_char(:input,'YYYY-MON-DD')) but this is giving the output in simple format which is defined by the oracle i.e. 'MM-DD-YYYY'.
We need the output in 'YYYY-MON-DD' and that too in date datatype.
I guess you understand my question.
Waiting for your response.
Thanks

i think you understand this :
SQL> select to_date('2013-06-13','yyyy-mm-dd') from dual;
TO_DATE('
13-JUN-13
SQL> alter session set nls_date_format = 'yyyy-mm-dd';
Session altered.
SQL> select to_date('2013-06-13','yyyy-mm-dd') d from dual;
D
2013-06-13
SQL> alter session set nls_date_format = 'dd.mm.yyyy';
Session altered.
SQL> select to_date('2013-06-13','yyyy-mm-dd') d from dual;
D
13.06.2013
SQL> exit
but if you have windows except alter session set you will need to see REGEDIT and Regional parameters.

An import updates a date datatype column to sysdate

Hi
I couldn't find anything on this issue in the document.
I did an export of the data of table1 from database A, in table1 I have a column called CREATEDATE and it has a DATE datatype. When I imported it into database B, all rows now have the current SYSDATE in the CREATEDATE column instead of the original content as on db A.
Any clues why an import would treat a DATE column like that? and how I can maintain the original content on an import for a DATE type field???
I do not have a sysdate as the default value for the column.
Your help is appreciated!

Sounds like you have a trigger firing. Triggers will fire during an import unless you disable them first. Try disabling all triggers on the tables being imported and see if that eliminates the problem.

Enforce date datatype in oracle 11g

Can I restrict database so that application can not enter date data in certain format.
E.g. If I want that date enter should be registered in [year to minute] 'MM-DD-YYYY' hh:mm' only format and not in [year to second format]'MM-DD-YYYY' hh:mm:ss' then how I can do it in Oracle 11g.
Currently I am using oracle sql developer to create data model and then I want to generate DDL from that to generate database. Is there is any facility in Oracle SQL developer to enforce format specification.
thanks!

This is not really related to SQLDeveloper, so you may find better answers in another forum but I'll try to give you an idea anyway.
Actually the DATE datatype has no format, you use a format when you convert it to a string or vice versa, but the DATE itself is just a DATE.
You could probably create a trigger to truncate your data as you see fit, but IMHO your best option would be to remove the seconds from your output queries using something like
TO_CHAR(YOUR_DATE_FIELD,'MM-DD-YYYY HH24:MI')you can also set this output format for SQLDeveloper in
Tools -> Preferences -> Database -> NLSbut this will work only for SQLDeveloper, it's up to you to determine the best way of setting the output/input date format in your specific application.

TRUNC function for DATE

Another thread from today made me think of the basics of TRUNC function used for DATEs. I am confused about what it acutally does.
This is what Oracle Documenations says about TRUNC function without format (like 'DD-MON-YY')
"If you omit fmt, then date is truncated to the nearest day" (Oracle 10Gr2 SQL reference, B14200-02)
SQL> alter session set nls_date_format = 'DD-MON-YYYY HH24:MI:SS';
Session altered.
Query 1.
SQL> SELECT SYSDATE FROM DUAL;
SYSDATE
06-DEC-2007 14:22:01
Query 2.
SQL> SELECT TRUNC(SYSDATE) FROM DUAL;
TRUNC(SYSDATE)
06-DEC-2007 00:00:00I have three questions
1)Since it 2:22 pm , shouldn't the result of TRUNC(SYSDATE) ie Query 2. be 7-Dec-2007 ?
2) What difference does TRUNC function make in the code apart from setting the time to 00:00:00?
3) Is it safer to add TRUNC for DATEs in the code?
SQL> select sysdate-1 from dual;
SYSDATE-1
05-DEC-2007 14:27:51
SQL> select trunc(sysdate) - 1 from dual;
TRUNC(SYSDATE)-1
05-DEC-2007 00:00:00Added third question

it's not a function that rounds up date's it purely truncates to the granularity that you want.
So TRUNC(sysdate) still returns a date datatype (which still contains a date and time portion) but the time portion is truncated i.e. cleared down to it's lowest limit.
Likewise if you TRUNC(sysdate,'YYYY') then it will truncate to the year and take months, days, hours, mins and secs down to their lowest limit hence giving you 1st January of that year with 00:00:00 as the time.
It's very simple really.
