Duplicate rows in dimension

Hi All,
I created a time dimension in obiee (base table is a normalized table where we have hour,day,week,period,year) .When I pull year column in Answers I am getting lot of rows having the same year.Do we need to do some setting in obiee so that it returns only distict rows for year,period,week,day and hour.
Thanks in Advance

Hi
I got same problem with my time dimemsion as well... when you have created join between your time dimension to any other dimension then you would have created join using that year column.... from which your year column became key in time dimension.... and year is not your main primary key that is why i think it is giving you problem.. if you can't avoid this join relationship then create view on top your main time dimension and create year as separate column which should not be used for joining column....
i hope this will help you
thanks & Regards

Duplicate rows in Oracle

What would cause Oracle to insert duplicate rows into a table? Could a join of two tables in the initial query assigned to an application page cause ORacle to insert an extra row into a table when an update to data value occurs? I have no insert triggers and no foreign keys assigned to the table. I am not sure what would cause Oracle to assume that an insert of a row must occur. I want to prevent that insert.

I want to prevent that insert.Is there an APEX dimension to this? If so, tell us the full APEX and DB versions, and provide full details of what the APEX app is doing (a debug trace of page accept processing is the obvious place to start).
The most likely explanations are:
1. There is no duplicate in the table but there is a join problem in the query reporting on it, resulting in the appearance of a duplicate in the reults. Have you confirmed that the duplicate is really a physical row in the table?
2. There is an APEX page/application process containing an insert on the table that is unexpectedly running on page accept due to it having no condition or an incorrect condition. This will be visible in the Debug trace.

Duplicate rows in Multiselect

Hi All,
Our system have been recently upgraded to OBI 10.1.3.3.
We are facing a problem with the multiselect prompts in the application. Now some of the columns used as sources of the multiselect Dashboard prompts have duplicate rows.
Any idea how to suppress the duplicates and display only the distinct records?
Thanks in advance

If the values that you are using in your dashboard prompt are from tables that are considered 'Dimension' tables in the Business Layer, then you will be OK.
From what I understand, the Oracle BI server always does a select distinct when querying dimension only data. It's only when you combine data from Business Model fact tables, that it removes the DISTINCT from the SQL that is generated.
Hope this helps.

Duplicate rows being eliminated from OBIEE reports...

Hi,
Duplicate rows are being eliminated from OBIEE reports even though I have not specified the 'DISTINCT' clause under the advanced tab of the answers request.
I read somewhere that this is a bug and the only solution is to include the table key column.
Please let me know if this is correct or if there is another solutiuon to prevent this issue.
Thanks in advance.

Hi user11935561,
I've also noticed this too. And I did one of two things in the past:
1) Yes, when applicable, I've added a unique identifier to the report so that duplicates were shown.
2) Sometimes when I hit this I had a situation of a few dimensions in a report (lets say CUSTOMER and PRODUCT) and a measure (let's say sales $). If the customer 1 bought product A at $10, and he bought it on two different days, I was only seeing the DISTINCT record coming through, i.e. I was only seeing CUSTOMER 1 PROD A $10 instead of $20. Then I went into the RPD and changed the aggregation rule of Sales $ from None to SUM. The sum would force a group by get the correct information back from the RPD. So make sure you have your aggregate measures defined in the RPD and that should help you get around some of these issues.
Hope this helps!
Best regards,

Duplicate rows in Webi Report

Anyone can pls tell me how to avoid duplicate rows in a webi report. I have tried checking the 'Avoid duplicate row agg.' option as well as 'Retrieve duplicate rows'.
The query that is generated in the webi gives proper results wehn run at the database level but not in the report.
What can be the problem?

Hi VickyBobj,
It's hard to know, but my guess is the way the objects are defined in the universe. Make sure your measures are defined correctly, as sum, count, etc. and also make sure you have placed dimensions and measures correctiy within the report format - meaning generally dimensions in the headers and measures in the body.
Thanks

Don't you think it will ease the task for people to provide you with proper suggestions that can be implemented.
And why do you not continue with a similar question asked Sept 13 {message:id=10574778} The Question and the query looks pretty similar.

and
t1.UserIdin

order by t2.timein);
 
Thanks

Hi Rob,
Just trying to chip in little bit!
Created Table As follows same as you, only two rows with duplicatem user, datein, and timein:
create table table1
as
select '08:20:00' timein, date '2007-09-01' datein, '0001' locationin, 'U01' useridin, 1 status from dual union all
select '08:10:30', date '2007-09-01', '0004', 'U01', 1 from dual union all
select '07:20:00', date '2007-09-01', '0006', 'U01', 1 from dual union all
select '08:14:00', date '2007-09-01', '0001', 'U02', 1 from dual union all
select '06:10:30', date '2007-09-01', '0004', 'U02', 1 from dual union all
select '06:10:30', date '2007-09-01', '0001', 'U02', 1 from dual
If I run your delete statement result row will be as follows:
SQL> select * from table1;
TIMEIN DATEIN LOCA USE STATUS
07:20:00 01-SEP-07 0006 U01 1
06:10:30 01-SEP-07 0004 U02 1
06:10:30 01-SEP-07 0001 U02 1
Here problem is that its not able to delete duplicate rows having same timein and timeout.
So I changed you query as follows:
DELETE FROM tab1
WHERE rowid NOT IN (
 SELECT MIN(rowid)
 FROM tab1
 WHERE (UseridIn, TO_DATE(TO_CHAR(DateIn,'YYYYMMDD') || TimeIn,'YYYYMMDDHH24:MI:SS')) IN
 ( SELECT UseridIn, MIN(TO_DATE(TO_CHAR(DateIn,'YYYYMMDD') || timein,'YYYYMMDDHH24:MI:SS'))
 FROM tab1
 GROUP BY UseridIn)
 GROUP BY UseridIn
If I run your delete statement with little bit of changes, the result row was as follows:
SQL> select * from table1;
TIMEIN DATEIN LOCA USE STATUS
07:20:00 01-SEP-07 0006 U01 1
06:10:30 01-SEP-07 0004 U02 1

How to delete duplicate rows in oracle and retaining last duplicate rows

Hi,
I'm having millions of records in the table .Some duplicate values/rows are inserted in it.
I just want to delete duplicate rows but also want to retain the last duplicate row.
For eg if one record is found three times ,i want to delete first and second record and retain
the third one i.e the last inserted one.
Regards

To start with, since you do not wish to keep multiple rows with same values, why allow them to get inserted in the first place?
Wouldn't it be easier to block duplicate rows from inserting by creating a Unique constraint on Column(s) that define a row as duplicate, then rather deleting duplicate rows periodically?
For deleting duplicate rows, there are N number of techniques available. Always remember, you need to have a rigid criteria that marks row as duplicate.
[url http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:15258974323143]this is one recomended by tom for large tables.

How to get duplicate rows in a large table

I have a table which consists of 26 columns and 2 milion records..while doing validation i suspect there are duplicate records in that table...
Is there any way to check duplicate rows in a table?

I went through link..in all the messages query is for 2 or 3 columns...but my scenario is i have 26 columns ...and i suspect there is duplicate row inserting .for which value is same for all 26 columns .how should i do .?
do i need to do group by all 26 columns and do having count(*) ...26 times?

Selecting duplicate rows based on a combination of columns as key

Hi ,
I have a table with 5 columns.
Code ID S_DATE E_DATE Name
1 23 01012001 null ABC
1 09 01012001 null XYZ
2 81 04022007 null TVU
1 43 03092008 null XXX
Now, I need write a select query to fetch the duplicate rows from the above table having the combination of (Code, S_DATE,E_DATE) as the key.
So from the above example, I need to get Row1 and Row2 as output (but not Row3 as it has a different S_DATE)
Thanks in advance for your suggestions.
Thanks

To avoid duplicate rows in oracle 8i

Can you suggest how to prevent duplicate rows while in situations where multiple refreshes from a single export file using Oracle 8.1.7?
Do i need to specify Commit=Y, Constraints= N and IGNORE=N while importing data?
Your suggestion would be appreciated.
Thanks in advance.

PK or not pk, if you set ignore=n, the import will be abort in case of table already exists, so you won't have any duplicate rows.

Deleting duplicate rows based on three columns in Oracle 8i

Hi all,
The database we use is Oracle 8i.
The query below raises the too_many_rows exception when I launch an application. So I want to delete the duplicated rows :
select polarisation_1, polarisation_2
into v_pol1_tech, v_pol2_tech
from v_cfh_lien_element
where nom_lien = p_nom_lien
AND num_canal_1 = p_num_canal_1
AND freq_emise_1 = p_freq_emise_1;
Notice that with many possible values of the parameters p_nom_lien, p_num_canal_1 and p_freq_emise_1 then the exception is raised.
So how to delete generally the duplicated rows based on the three columns "nom_lien" , "num_canal_1" and "freq_emise_1" ?
Thank you very much indeed.

Crystal report duplicate row problem

Hi expert,
Need help about crystal report for my customer, want to make report about outgoing payment(OVPM) but it become duplicate row for detail because 1 payment include lot cheque(VPM1) more than 1,i just want to know if there got other method to avoid duplicate row.I also try put formula for detail area "{VPM1.CheckAct} = Next({VPM1.CheckAct})" or "{VPM1.CheckAct} = previous({VPM1.CheckAct})"..it useful for 1 row only,if i put more row,it will eliminate other row,just show 1 row.
Here is my query take from crystal report.

Remove: LEFT OUTER JOIN "OACT" "OACT_3" ON "VPM1"."CheckAct"="OACT_3"."AcctCode"
