Comparing data in two data sets in Oracle BI 11g

Hello,
I'm trying to compare the PO status of two systems and display the ones that donot have the same status. I'm able to join the data-sets with the link but unable to compare them. Can you please tell me?

Are you referring to BI Publisher 11g links !! Shed some light on your issue.

How to get the data between two dates?

Hi all,
I am facing a problem of getting the data betwwen two dates.
I have written a query as
"select * from table1 a where a.dt between trunc(sysdate) and trunc(sysdate)-30"
It is not showing any errors or warnings.But the data is not coming though the data is in the table1 between these two dates.
Regards,
Kumar

Your ordering is probably wrong:
SELECT *
FROM table1 a
WHERE a.dt BETWEEN TRUNC (SYSDATE) - 30 AND TRUNC (SYSDATE)

Findig dates between two dates

Hi everybody,
I have one table (TEST) with 2 columns having only one record
i need list of dates between from_date and to_date
the sample data...
from_date to_date
====== ======
02-JUL-09 17-JUL-2009
I found below query to retrieve the dates between two dates.
select to_date('02-jul-2009','dd-mon-yyyy')+level-1 dt from dual
connect by level<=to_date('17-jul-2009','dd-mon-yyyy')-to_date('02-jul-2009','dd-mon-yyyy')+1
It is working properly.
i have changed the above query with my table column names
select to_date(from_date,'dd-mon-yyyy')+level-1 dt from Test
connect by level<=to_date(to_date,'dd-mon-yyyy')-to_date(from_date,'dd-mon-yyyy')+1
In this case it is not working...
i am unable to find the reason...
Thank you.

Hi,
It is working fine for me, what is the data type for from_date and to_date.

How to compare data in two data sources ?

Hi,
Avalaibilty : Two data Souces 1) Based on standard data available from External agencies ( FLAT FILE )
                                                  2) Generic Data Source having Source system as R3 Server.
Requirement : To write a transfer routine such that each data transaction in the data field of R3 servers compares itself to the the respective data available in the external data source and updates the Infoprovider ( DSO ) accordingly .
Exact problem : I want to check the no. of employees in my company that are using travel funds more than the iNdustry standard for the respective position and also if they are spending more than Industry standard altogether ( OR Conditioon ) .
What would be the structure of the Routines ? and how to comparre
Mrinal

Hi,
Below logic can be used:
Load the flat file data in DSO2. Then compare and insert the matching value a temp table TABLE1.
SELECT <KF1>
           FROM <DSO1> INTO TABLE <TABLE1>
           WHERE <KF1> = <DSO2>/<KF2>;
Then insert the contents of the temp table into the required CUBE/DSO.

Dates between two dates

HI everyone!
I'm trying to obtain the dates between two given dates....
example:
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date a = sdf.parse("12/10/2005");
Date b = sdf.parse("22/12/2005");My desired result its a ArrayList of all dates between that period...
I already used the GregorianCalendar adding one day in a while condition until its equals the second date but it dosn't work for large periods of time...
Can somebody help me with this task?
thanks in advance !

while(gc.getTime().compareTo(finaldate ) != 0){No, that's still fragile. You're still comparing EXACT values, instead of checking for when one equals OR EXCEEDS the other.
If you're not going to use DrLaszlo's example to use the Calendar class for a better way, then at least do this instead:
while(gc.getTime().compareTo(finaldate ) < 0){

Occurrence of a date between two dates

I want to find occurence of a particular date between two given dates.
for example if I have 01/03/2006 and 01/01/2007 and I want to find
if an 06th April exist between them, how do i find it?Pls help.. it's very urgent.
Thnx
RK

Pls help.. it's very urgent.I hate this. If you started your homework a couple days before it was due, you wouldn't have this problem
Anyway see
Date.getTime()
and
Calendar.getTimeInMillis()
If you've only got a String date, see SimpleDateFormat
Once you have them all in long values, just compare the numbers to make sure the new date is > one of them and < the other

To filter data in two dates using combo box component

Hi,
I have a requirement like, i need to filter data in chart between two dates from two combo box.. From combo_box and To combo_box.
I am using one QaaWS to populate LOV's into Combo box's and another QaaWS for chart data. Universe is the same one on SAP BI query.
LOV's are populating into both combo's and chart as well, i used a query refresh button after choosing two dates and press button.
Data is not reflecting as per the choice of dates.
If any one have such scenario, request you to share the same....
Thanks in advance...
Raj..

Problem is with ranges, not with dates, my data is working fine with CALDAY (in BI Query)....
My query variable is on FiscalPeriod month, like "FEB 2011" to "OCT 2011" and is optional, but it is fails in QaaWS to execute when i try to input any months.
If we give default values in BI query format is like K4/010.2011 for october month. QaaWS doesnt fail and executes, but if i change any value in QaaWS it is taking as "OCT 2011"
And in Xcelsius it is not recognizing eaither of the formats like, K4/010.2011 or "OCT 2011"
the format is not matching with xcelsius.

Data from two data providers

In a report i want to fetch teh data from 2 data Providers. which condetion wil satisfy to link the 2 data providers.
ex: Q1 have columns A,B,C
Q2 has a X,Y,Z columns.
requirement is like i want to get all the columns from those 2 tables in report level..like A,B,C,X,Y,Z in a single report.
Regards
Sunil

Hi,
As venu and karthik said you must a have a atleast one common dimension (same date type for both dimensions) two link two data providers to get a single report.
For ur requirement check whether any one dimesions exists in both data providers. If so then goto Data Manager -> expand 1st DP ->select the common dimension -> right pane (at bottom) you will get link to button -> click and select the common dimension in 2nd DP.
Repeat the above process for all the common dimensions and then drag and drop all the required objects to create a single report.

Hi Frank,
Sorry for my fault,
The following is my table description,

     "TODATE" DATE,
                   "LEAVE_ID" Number(5)
Insert into dates values('05-02-2012','05-05-2012',1);
Create table holiday_dates(holidays date);
insert into holiday_dates values('01-05-2012');Now when I used this query,
select count(*) from (select dt
from(
    select to_date(fromdate, 'DD-MM-YYYY') + rownum -1 dt
        from dates
        connect by level <= to_date(todate, 'DD-MM-YYYY') - to_date(fromdate, 'DD-MM-YYYY') + 1
where to_char(dt,'fmday') not in ('sunday','saturday') minus (select holidays from holiday_dates)) dual;
Count(*)
   64
Insert into dates values('01/05/2012','05/05/2012',2);
/Now my table has 2 rows,
select * from dates;

You either have a SQL problem and this is the incorrect place to ask.
Or you have a Java problem in code we cannot see. When posting code use the code tags. Click the CODE button and paste your code between the tags that appear.

How to get list of all the dates between two dates

Hi, Can anybody please help me ..
I have two dates in string format ("dd/MM/yyyy).I need to get all the dates in between these two dates.How can I do thin in java
Thanks in advance

Look at classes Calendar and SimpleDateFormat.
And get your abstraction straight: you don't have two dates. You have two Strings that represent a date. To use them, you have to convert them to Date objects first with SDF.

Setting up Oracle DB 11G in a development environment

Hi
I need to setup a new development environment with Oracle Database 11g and Oracle Apps Server 10G Forms and Reports.
Currently we are running a live system (using Microsoft Virtual PC) on a domain and the virtual servers are joined to the domain.
Where I want to get to with the new development environment is to be able to eventually move these new virtual servers to a completely new domain.
What would be the best way to set this up to minimize the amount of work when setting up the database and apps server with the assumption that I will want to migrate the virtual servers to a new domain in the future. Would it be better to set up a basic workgroup and do the installation of both virtual servers in a workgroup environment?
Also besides having security enhancements is there any advantage of having Oracle installed on a server versus installing on a Windows XP box?
Many thanks.
Spencer

İf you first try to create db you get above errors, then you select "Create new objects in schema" option drop&create process starts.
Result :
TESTTYPEıD_TRG, CUSTOMOPTıONıD_TRG , ıSSUEVERSİONTYPEıD_TRG triggers are dropped and but not created again. ETESTPAGEID_TRG, TESTCASEATTACHMENTID_TRG, ATTCHSTDATA_TRG are newly created instead
As I mentioned above after creation of ATTCHSTDATA_TRG, it throws an error and process stop. In additon, due to this error, all the dropped views are not created again.
All my problem is newly created triggers an couldnt created views I suppose.
Please advice
thank you

Data between two dates in a 12-month period

Hello Gentlemen
I am facing a problem hope you would solve it.
I have a table
CREATE TABLE MATCHES
(MT_ID     NUMBER(4) CONSTRAINT MT_ID_PK PRIMARY KEY,
START_DATE     DATE,
END_DATE     DATE,
TEAM_A     NUMBER(2),
TEAM_B     NUMBER(2),
SERIES_ID     NUMBER(3))
INSERT INTO MATCHES (MT_ID,START_DATE,END_DATE,TEAM_A,TEAM_B,SERIES_ID) VALUES(1,'1 Apr 1993', '5 Apr 1993',1,2,1);
INSERT INTO MATCHES (MT_ID,START_DATE,END_DATE,TEAM_A,TEAM_B,SERIES_ID) VALUES(2,'21 Apr 1993', '25 Apr 1993',2,1,1);
INSERT INTO MATCHES (MT_ID,START_DATE,END_DATE,TEAM_A,TEAM_B,SERIES_ID) VALUES(3,'30 Mar 1994', '3 Apr 1994',4,2,1);
INSERT INTO MATCHES (MT_ID,START_DATE,END_DATE,TEAM_A,TEAM_B,SERIES_ID) VALUES(4,'1 May 1994', '5 May 1994',8,1,1);
INSERT INTO MATCHES (MT_ID,START_DATE,END_DATE,TEAM_A,TEAM_B,SERIES_ID) VALUES(5,'24 Nov 1994', '28 Nov 1994',5,7,1);
INSERT INTO MATCHES (MT_ID,START_DATE,END_DATE,TEAM_A,TEAM_B,SERIES_ID) VALUES(6,'31 Mar 1999', '4 Apr 1999',3,6,1);
select * from matches order by 1
MT_ID     START_DATE     END_DATE     TEAM_A     TEAM_B     SERIES_ID
1     01-APR-93     05-APR-93     1     2     1
2     21-APR-93     25-APR-93     2     1     1
3     30-MAR-94     03-APR-94     4     2     1
4     01-MAY-94     05-MAY-94     8     1     1

6     31-MAR-99     04-APR-99     3     6     1Where
MT_ID is Match ID which is primary key
stat_date is the start date of the match and end_date is the date on which the match ended.
Each match has two teams i.e Team A and Team B. Each team has its unique ID. So in the above data there are eight teams form
ID 1 to 8.
Duration of match can be taken out if we minus the start date from the end date. For example:
Select END_DATE-START_DATE +1
From MATCHES
END_DATE-START_DATE+1
5
5
5
5
5
5 1 is added to include the start day too.
My requirment is as follows:
For each of the 8 Teams, show
1. How many matches they played in each of the 7 twelve month periods from 1 April 1993 to 31 March 2000? If a match overlaped a 12 month period, then it would be treated as one match each on either side on the 12 month period.
For example, if a match started on 30 March 1994 and ended on 3 Apr 1994 then for the 12-month year starting from 1 Apr 1993 to 31 March 1994 it would be treated as one match and for the 12-month period starting from 1 Apr 1994 to 31 March 1995 it would be treated as another match. Becuase the match was split into 2 + 3 days on either side of the 12-month period.
2. How many days each team was playing a match in each of the 7 twelve month periods from 1 April 1993 to 31 March 2000?
For example, a team played 3 matches between Apr 1, 1993 and Mar 31, 1994. The Duration of each of the matches was 5+5+5 = 15 days. But the third match overlaped the 12-month period which started on 30 Mar 1994 and ended on 3 Apr 1994. So the correct number of playing days for that team would be 5 + 5 + 2 = 12 days from Apr 1, 1993 and Mar 31, 1994.
A want an efficient query that gets me both of the above answers
My desired output is like this:
For Team ID = 1
Period                       MT   Playing Days
1-Apr-1993 to 31-Mar-1994    2    10

Dear Oscar
Thanks for your feedback. Yes, this problem has to be resolved becuase SQL from browser is better to work with. The command prompt SQLPlus is not user friendly.
Any way, Oscar I checked your last query on the sample data that I also posted in my question. It was fine. But when I ran the query on my actual base table it did not gave me the correct results for frequency of six weeks gap. It showed 0 for even those gaps where there is actually a six week gap and where there was a gap of atleast six weeks on more than one ocassion in a 12-month period it shows only 1 for those.
THe "Free days" were however generated correct by the query and its further accumulution to next period at cut-off point (31-Mar-YYYY) is also correct..But I missed to tell you one thing which I explained below.
The is no difference in between the base tables and the dummy table. The only difference is ofcourse the data and the number of records.
For this reason I copied here actual base table DDL data (54 records) in order to solve the
problem.

This one six-week gap is very well showed by the result of your query below. But in the period from 01-Apr-2003 to 31-Mar-2004 your query below does not show any six-week gap. whereas in the same period, above the results show four instances of atleast 42-days gap. i.e. 73, 71, 43 and 61 days.
So your query should show the following for this period:
TOT   TEAM PERIOD                    FREEDAYS EXISTS_SIX_WEEK_GAP
-      1   01-Apr-2003 to 31-Mar-2004   296   4   Same is true for the next period 01-Apr-2004 to 31-Mar-2005.
For other TEAM ID's the six-week results generated by your query are ok, becuase for each of those teams, except for Team = 21, there was only one instance of 42 days gap. The query fails only when there is more than one 42-days gap.
For Team = 21, The query shows 1 instance of six-week gap but doesn't show the number of free days for that period. This is mainly becuase I told you in my question the other day that Free Days are calculated by taking the diffrence between the end date of the previous match and the start date of the current match. Since team = 21 played only one match so that's why the query showed no free-days becuase it did not found any previous date to take the difference. For this purpose I rephrase my question below the following table.
When I run your query, modifying the start period to 1-Apr-2002 instead of 1992 and connect by
level <= 5,
with periods as ( select add_months(dt,12*(rownum-1)) start_period,
                         add_months(dt,12*rownum)-1 end_period
                  from (select to_date('1-Apr-2002') dt from dual)
                  connect by level <= 5),
....,on my actual data it gives me the following result:

TOTAL 21                         -      0    1   I want that Free-days should be calculated in the following way:
1. The number of free-days for each team would be calculated by the taking the difference between the end-date of the previous match and the start date of the current match.
2.If there is no previous match or the current match is the first match of the respective team in that 12-month period then the number of free-days would be calculated by taking the difference between the start date of that respective period (say 1-Apr-2002) and the start date of the current match. For example, Team = 21 played its first and only match in the 12-month period (01-Apr-2005 to 31-Mar-2006) from 14-19 OCT-,2005. So for this team the number of free days in this period would be 196 days (from 1-Apr-05 to 13-Oct-05) before this match and since no further match is played by this team in that period so the free days (163) from 20-Oct-2005 till 31-Mar-2006 (period end) would also come into this period. Hence the total number of free days by team = 21 in this period would be 196 + 163 = 359 days. The six-week gaps were two for this team in this period. Similary, for Team = 1 in the period from 1-April-2002 to 31-mar 2003, it played it first match from 03-07 OCT, 2002. Its free days for that period currently shown are 140 but
they should be 325 (140 + 185 days ==> from 1 April 2002 to OCt 2, 2002).
3. If a team plays its last match in any period well before end period say by Jan 6, 2007, then the period from Jan 7 to March 31, would also be counted in the free days. If the current date or SYSDATE is less then March 31, 2007, then the free-days would be counted from Jan 7 to current date or SYSdate.
4. If a team played no match in any period then the total number of days in that period would come as free days and this would count as only 1 six-week gap in that period.
5. If the free days overlaped a 12-month period then the number of free days that came till the end of the period break point would come into the preceding period and the remaining number of free days would come in the next 12-month period. For exmaple, a team played a match from 01-MAY-94 to 05-MAY-1994 and then played its next match on 01-APR-1999 to 05-APR-1999. So the number of free days between 06-MAY-1994 TO 31-MAR-1999 are 1791 days. (This condition is already well done by your current query). Lastly, for an overlaping gap (over 2 or more periods), the frequency of atleast six-weeks would only come in the period from where the six-week gap started.
I would prefer results in the format below. The free-days gaps in each period are breaked-up into actual gaps, showing the start and end date of the gap and the number of days and the "1" if the gap is of atleast 42 days. the first line of each period shows the sum of the total number of playing days between that period, sum of free days for each period and the sum of six-weeks for that period.
