Usage of TAble Functions in OBIEE

Hello All,
I have created a table function in the database.
Is it possible to use/call table functions in obiee.Please let me know how to use table functions in OBIEE.
Thanks in advance.

Hi,
Thanks for your reply.
I want to use this table function to generate answers report.
In the query i am using unions,bind variables.I can not create a database view on this query.The best solution would be creating a table function.
But,i do not know how to access/use/call this table function to create answers report.
Thanks in advance.

How to use Table valued MSSQL function in OBIEE

Hi all,
Can some one help me to understand how to use table valued function in OBIEE? I want to use a table valued function (MSSQL function, with some input parameter), in the physical layer to pull the data?
I know for MSSQL Stored Procedure we can write as
EXEC SP_NAME @Parameter = 'VLUEOF(NQ_SESSION.Variablename)'
but now I have a table valued function in the query window I can get the data as
select * from myfunction(parametervalue)
In physical layer of OBIEE I have tried as
select * from myfunction('VLUEOF(NQ_SESSION.Variablename)'), but I'm getting error as the NQ_SESSION variable doesn't have a value , but actually I have initialized the variable but still Im getting error.
Can some one help me to solve this.
Thanks,

OBIEE Usage Tracking Table Is Not Populated

Hello everybody,
OBIEE Usage tracking table (s_nq_acct) is not populated correctly for last a few weeks. I have no experience on configuring / managing usage tracking jobs, so I do not know where to start to solve this problem. First of all, which log file should I go to find the problem? And also which parameters should I look? Can you help me please.
Regards,
Dilek

Check that the absolutely correct and precise connection pool information contained in your RPD matches what your entries in the MBeans which then get written to the NQSConfig.ini.
Check that your UT physical model in the RPD physical layer isn't and old (11.1.1.5) setup running on a 11.1.1.7 env where the column definitions don't match.
Several log files. NQServer.log and NQQuery.log to begin with.

OBIEE 11G - Usage Tracking - Table S_NQ_DB_ACCT

Hi
I successfully set up usage tracking in Obiee 11 and the table S_NQ_ACCT gets a lot of new records. Basically it's working.
In the nqserver.log I get some errors concerning a new table S_NQ_DB_ACCT:
[nQSError: 17001] Oracle Error code: 942, message: ORA-00942: table or view does not exist
at OCI call OCIStmtExecute: INSERT INTO S_NQ_DB_ACCT (ID,LOGICAL_QUERY_ID,QUERY_TEXT,QUERY_BLOB,TIME_SEC,ROW_COUNT,START_TS,START_DT,START_HOUR_MIN,END_TS,END_DT,END_HOUR_MIN) VALUES (:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11,:12).
This is an additional Usage Tracking Table which didn't exist in OBIEE 10G.
I configured the table as S_NQ_ACCT in the same place in the repositry/connection pool. Writing to this table should be possible.
Does anybody has an idea what could be wrong? Does another user fill data to this table than the user which fills data to S_NQ_ACCT?
Thank you

Hi
Thank you.
I use the table within the default RCU created schema. What I don't understand ist why the table S_NQ_ACCT gets a lot of records (because I set the loglevel) but S_NQ_DB_ACCT keeps empty with the error in the nqserver.log. I mean if one table works then the other should be working too? I checked also the permissions which are the same for both tables.

Evaluate function in OBIEE

Hi All,
I tried using Evaluate and Evaluate_Aggr in the column formula of a report.
Evaluate_Aggr() is erroring saying the dimension Work Order is incorrectlly defines logical Table Source Mapping for a dimension of Work Order. If I revoke the implicit fact coniguration on this Subject Area which I have, the report executes as expected. But this implicit configuration is required in my scenario for other reports to work.
Using Evaluate() works perfectly.
Can anyone help me in fixing this?
Shld I add any other configuration in the RPD to resolve this issue?
Thanks

Unable to use WriteBack function in OBIEE on a Unix setup

It's already good to know that the file gets picked up.
What I don't understand: "The log files are not being updated with the error however when I re-save my Answer it is populating the log file to state that the object already existed."?
I had to put a fake "insert" statement to get it working once. Here's the example:

Urgent - INSTR() Functions in OBIEE?

Hi All,
I just got some very good help from the DB experts on these forums about solving a problem with a table join that I had.
But now I have this SQL query and I'm trying to figure out how to implement this in OBIEE:
select *
from TABLE1,TABLE2
where instr(TABLE2.USER_ID,TABLE1.USER_ID) > 0
My question is how do I implement this instr() function on OBIEE? I checked physical and business model mapping layers in the repository and it does not allow me to configure this type of join. Is it possible to configure this type of join function to be invoked automatically everytime a user runs a certain query in OBIEE (as if it was a natural join)?
Any help would be greatly appreciated.
Alan

Does using TABLE FUNCTIONS degrades performance

Hi,
I am using a TABLE Function TABLE(TABLEA)
I am using a SQL Statement where I am joing TABLE FUNCTION :TABLE(TABLEA) and Normal table:TABLEB
i.e
SELECT CODE,SUD FROM TABLEB,TABLE(TABLEA)
WHERE CODE=CODE1 (CODE1 is a Object Type variable).

i.e
SELECT CODE,SUD FROM TABLEB,TABLE(TABLEA)
WHERE CODE=CODE1 (CODE1 is a Object Type variable).One particular issue with table functions and joins is that the optimizer doesn't have a clue about the cardinality, i.e. the number of rows returned by the table function and therefore applies defaults which might be way off. If you somehow know roughly how many rows are going to be returned (may be a quite constant number of rows or your process know the number of rows in a collection etc.) then you can help the optimizer by using the (undocumented) "CARDINALITY" hint, e.g.
SELECT /*+ CARDINALITY (A, 100) */ CODE,SUD FROM TABLEB B,TABLE(TABLEA) A...
tells the optimizer that the table function is going to return 100 rows. Note the usage of the alias in the hint.
But bear in mind that this only helps partially, some other basic information like column statistics are still missing and therefore the estimates of the optimizer still might be inaccurate.

Converting Decode function in OBIEE

Hi Guru's
we are converting some BO reports to OBIEE and need to convert Decode function
Below is the Decode function they are using:
Decode ( sign(nvl(BOOKINGS_DATA_UDTC.qty_shipped,0)), 0,decode(BOOKINGS_DATA_UDTC.DELIVERY_NUMBER, 0,decode(BOOKINGS_DATA_UDTC.Schd_Ship_date_fk,to_date('1/1/1990','mm/dd/yyyy'),'Next Month Backlog',decode(sign(nvl(BOOKINGS_DATA_UDTC.Schd_Ship_date_fk, '01-JAN-90') -PAR.PAR_DATE), 1, 'Next Month Backlog', 'Current month will ship')) ,'Awaiting for collection') ,'MTD Shipped')
i have tried converting into case :
case when sign(IFNULL("BOOKINGS_DATA_UDTC"."Qty Shipped",0)) = 0 then (case when "BOOKINGS_DATA_UDTC"."Delivery Number" = 0 then (case when "BOOKINGS_DATA_UDTC"."SCHD_SHIP_DATE_FK" = '01-JAN-1990' then 'Next Month Backlog' else (case when Timestampdiff(SQL_TSI_DAY, cast('@{ParDate}{28-DEC-2012}' as Date),(case when "BOOKINGS_DATA_UDTC"."SCHD_SHIP_DATE_FK" IS NULL then CAst('01-JAN-1990' as DATE) else "BOOKINGS_DATA_UDTC"."SCHD_SHIP_DATE_FK" end)) > 1 then 'Next Month Backlog' else 'Current Month Will Ship' end) end) else 'Awaiting For Collection' end) else 'MTD Shipped' end
But it is not workign as expected.

How to use the Table Function defined in package in OWB?

Hi,
I defined a table function in a package. I am trying to use that in owb using Table function operator. But I came to know that, owb R1 supports only standalone table functions.
Is there any other way to use the table function defined in a package. As like we create synonyms for functions, is there any other way to do this.
I tryed to create synonyms, it is created. But it is showing compilation error. Finally I found that, we can't create synonyms for functions which are defined in packages.
Any one can explain it, how to resolve this problem.
Thank you,
Regards
Gowtham Sen.

Hi Marcos,
Thank you for reply.
OWB R1 supports stand alone table functions. Here what I mean is, the table fucntion which is not inculded in any package is a stand alone table function.
for example say sample_tbl_fn is a table function. It is defined as a function.It is a stand alone function. We call this fucntion as "samp_tbl_fn()";
For exampe say sample_pkg is a package. say a function is defined in a package.
then we call that function as sample_pkg.functionname(); This is not a stand alone function.
I hope you understand it.
owb supports stand alone functions.
Here I would like to know, is there any other way to use the functions which are defined in package. While I am trying to use those functions (which are defined in package -- giving the name as packagename.functionname) it is throwing an error "Invalid object name."
Here I would like know, is there any other way to use the table functions which are defined in a package.
Thank you,

Table function on a collection in Dynamic SQL

Hello,
I am trying to create a refcursor by selecting from a collection using table function.
If I use the Select statement the query executes, but if I put the Select statement in a string
the collection variable does not get resolved. The resaon I am putiing it in a string is because the
WHERE clause will be passed a parameter. The code below is an anonymous block but will be changed to a
procedure once I get it to work.
I have tried many different ways but was unsuccessful.

Performance issues with pipelined table functions

I am testing pipelined table functions to be able to re-use the base_query function. Contrary to my understanding, the with_pipeline procedure runs 6 time slower than the legacy no_pipeline procedure. Am I missing something? The processor function is from [url http://www.oracle-developer.net/display.php?id=429]improving performance with pipelined table functions .
Edit: The underlying query returns 500,000 rows in about 3 minutes. So there are are no performance issues with the query itself.
Many thanks in advance.
