SYSDATE Vs CURRENT_DATE

Select sysdate, double current_date;
Select sysdate - double current_date;

the first query result is same and second zero return... What is the difference between them? When we are use sysdate or current_date? Please help me...

Hello

sysdate is the current date on the server where the database resides.

Current_date is the date of the client from which you connect.

Current_date is a function and sysdate is not.

Becuse times your server date time and time of your customer data are the same, you get the result as 0.

You can change your time zone and do the same thing, then you will get different results.

ALTER SESSION SET TIME_ZONE = '-2:0';

select to_char(sysdate,'mm/dd/yyyy hh24:mi:ss') sys, to_char(current_date,'mm/dd/yyyy hh24:mi:ss') cur from dual;

    Hello

    We don't know what you want for the output.  Always show exactly the results you want from the data of the given sample.

    You do 3 different comparisons between the dates.  If the dates are independent, then you have 3 different CASE expressions, as the results of which you can unpivot on 3 different lines of output, like this

    WITH got_dates AS

    (

    SELECT id

    , TO_DATE (sdate, ' DD/MM/YYYY') AS sdate

    , TO_DATE (ACE, ' DD/MM/YYYY') AS

    , TO_DATE (edate, ' DD/MM/YYYY') AS edate

    T

    )

    got_spds AS

    (

    SELECT id, As

    , CASE WHEN sdate > ACE "sdate IS superior to ACEs ' END as spd_1

    , CASE WHEN sdate > TRUNC (SYSDATE) THEN "sdate is greater than the current date' END as spd_2

    , CASE WHEN sdate > edate THEN "sdate is greater than edate' END as spd_3

    OF got_dates

    )

    SELECT id

    As

    TRUNC (SYSDATE) AS current_date

    spd

    OF got_spds

    UNPIVOT (spd

    FOR n (spd_1 AS 1

    spd_2 AS 2

    spd_3 AS 3

    )

    )

    ;

    Or you could UNPIVOT 3 dates on 3 different ranks first and then use only 1 CASE expression.  I find the above path.

  • (Sysdate-1) in the name of the file using the Scheduler and ftp

    Hello

    I'm having a small problem with BI Publisher.
    What I'm trying to do, is use sysdate-1 in the file name when you use Task Scheduler to BEEP.

    I have found that by using the regular date it is features such as %d %m %y, so of course the first thing I tried was using the %d - 1, but that did not work :(
    Then I is picked up on the internet and found the following article:

    http://OBIEE-BIP.blogspot.com/2010/05/dynamic-delivery-file-naming-in-bi.html

    He mentions things like:

    DD: CAST (DAYOFMONTH (NOW ()) AS CHAR) (ex 01-31)
    Mon: CAST (SUBSTRING (MONTHNAME (NOW ()) FROM 1 TO 3) AS CHAR) (ex, Jan - Dec)
    AAAA: CAST (YEAR (NOW ()) AS CHAR) (ex, 2006,2010)

    But when I use those in the same field of file name, and then it just displays the string in the text file name.

    Could someone tell me what I am doing wrong, or what I have to do to make this work?

    Thanks in advance

    Hi Raafje,

    As I mentioned in my Blog, using the Date Expressions on filenames of query made irruption has its own limitations. This expression of date you tried sysdate-1 (%d - 1 %m %y) will not hang in the requirement. in any case, you can solve the problem by using alternative workaround.

    Method I (using CAST and DATE functions)
    1. standby-> CAST (DAYOFMONTH (TIMESTAMPADD (SQL_TSI_DAY-1, CURRENT_DATE)) AS CHAR)
    2 months of sleep-> CAST (MONTH (TIMESTAMPADD (SQL_TSI_DAY-1, CURRENT_DATE)) AS CHAR)
    3 year of Eve-> CAST (YEAR (TIMESTAMPADD (SQL_TSI_DAY-1, CURRENT_DATE)) AS CHAR)

    Code example
    + 'ReportName' |'-' | CAST (DAYOFMONTH (TIMESTAMPADD (SQL_TSI_DAY-1, CURRENT_DATE)) AS CHAR). » -'|| CAST (MONTH (TIMESTAMPADD (SQL_TSI_DAY-1, CURRENT_DATE)) AS CHAR). » -'|| CAST (YEAR (TIMESTAMPADD (SQL_TSI_DAY-1, CURRENT_DATE)) AS CHAR) |'. PDF "+

    Method II (using Server Variables)
    1. create a dynamic repository as Previous_Date Variable (Non - Session System variables can also be used)
    2. create a block initialization
    In the Data Source Section - edit the Data Source and place the query below
    Select TO_CHAR(SYSDATE-1,'MM/DD/YYYY')
    The DOUBLE (if necessary, you can use any date format)
    3. in the Section target Variable
    Change the target-
    Give the name as Previous_Date (that you created in step 1) and check the option as dynamic
    Place the date of default as "22/09/2010 '"
    4. now use this repository Variable in the parameter filename of the rafale as VALUEOF("Previous_Date") repository Variable query
    and VALUEOF (NQ_SESSION. Previous_Date) in case you created a session for the query variable

  • sysdate and systimestamp question

    Hello

    We have infrastructure of grid 11 GR 2 CARS with 10.2.0.5.0 (CRS) database with the UTC time zone.

    Recently, we changed the UTC time zone to the EAST for servers

    After changing the time zone, I've updated the dbtimezone parameter of ' 0.00' to '-'4.00 and recycled the entire grid (CRS), including the database, analysis listeners etc.»»

    Now, when I directly connect to putty and query sysdate and systimestamp, I am EST.
    But if I use the client / Toad or service, even within the server, it gives the hour UTC for sysdate and systimestamp.

    other parameters such as current_timestamp, current_date, localtimestamp etc. gives the same value in any way access

    If anyone can help.

    Hello!

    Please use

    setenv srvctl database d racdb t TZ = America/Chicago

  • ALTER Sysdate

    Hi all

    I'll put up a new Oracle Architecture with two different instances of DB in the same machine, each of them represents a different region with a different time zone.

    The main problem is that the two databases are running a PL/SQL application that uses Sysdate when inserting the current date in the tables. This is why we must find a way to change Sysdate in one of the databases to get the real time for each region.

    There is no way to change sysdate to a database?

    I was considering the following options, but none of them apply only to me.

    Fix_date parameter.

    Editing PL/SQL code to use current_date (time_zone setting change) instead of sysdate.

    Hello

    See you soon,.
    Rakesh

    Hello..

    You did not mention what kind of comparison, it is and where you want to do this?
    In any case, if you want to compare sysdate with timekey in the filters and then perform the following steps
    (Keyword equivalent for sysdate in BI is CURRENT_DATE )
    (1) to apply the filter on timekey to selecting the option to filter on column
    (2) select Convert this filter SQL (the option is something like that)
    (3) here, you write the CURRENT_DATE after your relational operator and if you wish, you can change the relational operator to < or=""> what you want...

    This is the way to compare your timekey with sysdate...
    But the other type of column data is should be TIMESTAMP or DATE data type...
    Here, in your situation, the TIMESTAMP data type timekey... well, you can compare easily... these...
    Please mark it as correct if you fell, it is OK and close the debate...

    Not easy to say why this is happening, but for me it s definitely something wrong with the software.
    Well, in this case we can only speculate. You know, it s Microsoft Windows and sometimes things happens without any reason :(

    I have heard from probably the system restore function could be corrupted and no have deleted the folder with the minidump and disabled the system restore feature in the control panel-> system.

    But in my opinion, the system restore function is important and necessary if you want to restore the operating system to the beginning.
    That's why I put t recommend disabling this feature.
