Query for functioning of Aggregate

Hello experts,
Could you please clarify me one fundamental question on the working of an aggregate.
I have a cube with the follwing information
CHAR1 CHAR2 CHAR3 KF 1
I have build an aggregate with
CHAR1 CHAR 2 KF1
I have my doubt here :
For example:
If I create a query with CHAR1 and CHAR2 in rows and KF1 in coloumns then the data is fetched from the Aggregate in stead of cube there by reducing the time. Is this correct?
OR
If I create a query is created with CHAR1 CHAR2 AND CHAR 3 in rows and KF1 in coloumns
then The data is read from the cube and noway the aggregate comes into picture.
Could you please clarify me how exactly the aggregate is working.

Hi,
Goto RSRT transaction>Give report name>Execute+Debug>a pop up sceen will appear with multiple check boxes>select "Display aggregates found" option--> It will show all the aggregates those are hitting the query.
To propose aggregates follow the below procedure to improve the query performance:
First try to execute the query in RSRT on which u required to build aggregates. Check how much time it is taking to execute.....and whether it is required to build aggregate on this querry?? To get this information, Goto SE11> Give tabl name RSDDSTAT_DM in BI7.0 or RSDDSTAT in BW3.x.> Disply -> Contnts-> Give from date and to date values as today, user name as Ur user name, and give the query name
--> execute.
Now u'll get a list with fields like Object anme(Report anme), Time read, Infoprovider name(Multiprovider), Partprovider name (Cube), Aggregate name... etc. If the time read is less than 100,000,000 (100 sec) is acceptable. If the time read is more than 100 sec then it is recommended to create Aggregates for that query to increase performance. Keep in mind this time read.
Again goto RSRT> Give query name> Execute+Debug-->
A popup will come in that select the check box display aggregates found--> continue. If any aggregates or exist for that
query it will display first if u press on continue button, it will display from which cube which fields are coming it will display...try to copy this list of objects on which aggregate can be created into one text file...
then select that particular cube in RSA1>context>Maintain Aggregates-> Create by own> click on create aggregate button on top left side> Give discription of the aggregate>continue> take first object from list and fclick on find button in aggregates creation screen> give the object name and search... drag and drop that object into aggregate name right side (Drag and drop all the fields like this into aggregate).---->
Activate the aggregate--> it will take some time once the activation finishes --> make sure that aggregate is in switch on mode.
Try to xecute the query from RSRT again and find out the time read and compare this with first time read. If it is less tahn first time read then u can propose this aggregate to incraese the performance of the query.
I hope this will help u... go through the below links to know about aggregates more clear.

Function returning SQL query for mutiple series in a chart

Hi,
I would like to know if there is a way to specify a single PL/SQL function returning the queries for multiple series in a 2D Line Flash Chart. I have multiple series in my chart that has different values in the where clause. I can write a PL/SQL function that can return all these queries in one shot. Is there anyway that I can specify this function as returning the queries for all the series in the chart?
As an example, assume that I am using the following three queries for the series in my chart:
select deptno, count(*) from emp where deptno = 10 group by deptno
select deptno, count(*) from emp where deptno = 20 group by deptno
select deptno, count(*) from emp where deptno = 30 group by deptno
I can't write a PL/SQL function that returns a query in the multiple series syntax (SELECT link, label, series_1_value [, series_2_value [, ...]]FROM ...) as I am using an aggregate function and my where clause is different for each series.
Thanks,
Rupesh

Hi Roel,
Thanks for your reply. I am already using an analytical function (RATIO_TO_REPORT(COUNT(*)) OVER () ) in my actual report. My problem is that the query for one series differs from the other only in one where clause. I will be able to dynamically able to generate all the queries for all the series in one pl/sql function. But the chart definition screen does not allow us to define a single function that returns queries for the all the series - possibly seperated by some seperator like S1: select.... S2:select and so on.

Rupesh

Hi Friends,
sorry to trouble you,i did not have oracle instance installed on my machine to check the query ,
this is some test query which is some resemblance with actual query in my project
actually the requirement is like this ,this is the master table
NO amount
 1 10
 2 100
 3 120
 4 50
 5 41
using some decoding function in the query the result came like this
NO decode(amount,......) quantity
 1 10
 2 -10
 3 -20
 4 -30
 5 41
on this decode function i am trying to using aggregate function SUM,but in that case in stood of giving
ABS value , it is giving in proper value like below result
NO decode(amount,......) quantity aggregate sum
 1 10 10
 2 -10 20
 3 -20 40
 4 -30 70
 5 41 111

Count() function throws error in EQL query for metric

Hi
I am trying to use count function in EQL query for Metric Bar to show the number of occurrences of a record.
When the record type doesn't exist i expect the function to return count as 0. Instead the function throws a runtime exception and the whole Metric Bar portlet fails, with error No Results Available. Even though other components in the metric bar have valid results.
2013-02-21 13:03:51,216 WARN [MetricsBarQueryProcessor] The EQL query does not return any results.
2013-02-21 13:03:51,216 ERROR [MetricsBarQueryProcessor] The EQL query does not return any results.
2013-02-21 13:03:51,216 WARN [MetricsBarResultsProcessor] No statement results to process.
The EQL query i am using is
RETURN NUMBER_OCCURS AS SELECT COUNT(EMP_ID) AS NUMBER_OCCURS where EMP_NAME IS NOT NULL group;
I tried using COALESCE but that doesn't help.
Can some one please suggest a workaround to this?

Srikanth,
Two statements are used here because the original question was pertaining to the null set (where there are employees in the nav state but no employees that fit the special analytics criteria in the navigation state). The question/answer has nothing to do with what is in the COUNT parentheses clause as Counting a null set will always give you NULL, not 0, no matter what you put in there.
What we're really doing, in the second part of the query, is writing a query over a set of data that is not the null set (i.e. the current navigation state). This allows the 0 value to come through in the case where the first analytics statement is evaluated over a null set of records. If there were truly no records in the navigation state, this too would return a null set and not zero.
Hope that makes sense, feel free to respond (either on here or offline) if it's unclear.

Query for getting all function and procedure inside the packages

hi All
Please provide me Query for getting all function and procedure inside the packages
thanks

As Todd said, you can use user_arguments data dictionary or you can join user_objects and user_procedures like below to get the name of the packaged function and procedure names.
If you are looking for the packaged procedures and functions source then use user_source data dictionary
select a.object_name,a.procedure_name from user_procedures a,
user_objects b
where a.object_name is not null
and a.procedure_name is not null
and b.object_type='PACKAGE'
and a.object_name=b.object_name

Applying functions to database fields when querying for a form field

Hi,
how is it possible to apply trim() or another method to the content of a database field when a query is initiated?
The actual problem is that there are entries in the database which are entailed by a blank and, because the user is not aware of this fact, he cannot be forced to add a blank or % to the form field he is querying.
Does anyone have an idea how to solve this issue?
Thank you very much in advance.

The where clause is built that way:
WHERE (ETN.trim(ETN_PLZ)=:1)
The error message:
ORA-00904: "ETN"."TRIM": invalid identifier
Actually, I guess that the trim statements should surround ETN.ETN_PLZ but that is obviously not the case.
Apart from that I did not enter 1 as the value to query for.
Nevertheless, thank you for your help. Forms version is 10.1.2 by the way.

How can I use AGO function with aggregates

I use aggregated table and a detailed table
I have time hierarchy whose lowest level is date. For sales I
created year-to-year (YTD) comparision with AGO function. It
works OK.
BUT, I want to speed it up, so I used aggregates. I created new
time table grouped by MONTH and corresponding agg_SALES table. I
created connections and mapped the fields. It works OK for
normal queries, that means my queries at month level use
aggregates. BUT when I add YTD measures or YAGO measure in query, it goes to
then SALES table whose grain is date.
How can I force BI Server to use AGO function with aggregates?
I use OBIEE 10.1.3.4
Thank you

Hi,
you can not do it in Administration tool but you can set agregation for that field in Answers (fx->Agregation rule->Sum) and effect should be the same. Note that it may not work properly on Oracle 10g as generated SQL is not 100% recognized, on 11g everything is OK (at least in my case).

Analytic function and aggregate function

What are analytic function and aggregate function. What is difference between them?

hi,
Analytic Functions :----------
Analytic functions compute an aggregate value based on a group of rows. They differ from aggregate functions in that they return multiple rows for each group. The group of rows is called a window and is defined by the analytic_clause. For each row, a sliding window of rows is defined. The window determines the range of rows used to perform the calculations for the current row. Window sizes can be based on either a physical number of rows or a logical interval such as time.
Analytic functions are the last set of operations performed in a query except for the final ORDER BY clause. All joins and all WHERE, GROUP BY, and HAVING clauses are completed before the analytic functions are processed. Therefore, analytic functions can appear only in the select list or ORDER BY clause.
Analytic functions are commonly used to compute cumulative, moving, centered, and reporting aggregates.
Aggregate Functions :----------
Aggregate functions return a single result row based on groups of rows, rather than on single rows. Aggregate functions can appear in select lists and in ORDER BY and HAVING clauses. They are commonly used with the GROUP BY clause in a SELECT statement, where Oracle Database divides the rows of a queried table or view into groups. In a query containing a GROUP BY clause, the elements of the select list can be aggregate functions, GROUP BY expressions, constants, or expressions involving one of these. Oracle applies the aggregate functions to each group of rows and returns a single result row for each group.
If you omit the GROUP BY clause, then Oracle applies aggregate functions in the select list to all the rows in the queried table or view. You use aggregate functions in the HAVING clause to eliminate groups from the output based on the results of the aggregate functions, rather than on the values of the individual rows of the queried table or view.
let me know if you are feeling any problem in understanding.
thanks.

Can't find FILTER CONDITION for filters or Function_Name for Functions

In the Data Warehouse 11gr1 views all_iv_xform...
I can't seem to find the Filter Conditions for filters and function name for functions that are called.
I have looked at the other views in the documentation for the API's but can't seem to find this information.
Any body have any ideas where this information is?

select map_component_id, position, source_parameter_name

WHERE MAP_ID IN (
select MAP_ID

from ALL_IV_XFORM_MAP_PROPERTIES
where map_component_id = :p_comp_id;

Problem with query for Oracle

Hello Experts,
I'm tryng to develop my first application for EP (v7 SP12) with NWDS (without NWDI).

I'm using:
a Dictionary Project (define the DB Tables)
a Java Project (define class as DAO, DBManager etc)
a Library Project
an EJB Project
an EAR Project
With these projects I can deploy a webService in my EP server.
BUT I have some problem with a query that I'm tryng to sent to my DB through a DAO Class called by my WebService.
The query is simple and correct but it does not work...
This is the error message returned (the query id in bold)

Any help???

Hi, I found something about the Host Variable (http://help.sap.com/saphelp_nw70/helpdata/en/ed/dbf8b7823b084f80a6eb7ad43bdbb9/content.htm), there explain that if you want to use an host variable you have to put ':' as prefix..
My problem is that I need to extract the minimum of the subtraction between two dates:
Query MIN(? - GIORNO) --> Error: the arithmetic expression >>? - "GIORNO"<< contains a host variable (parameter marker)
So I tried to use the ':' as indicated in the manual..
MIN:(? - GIORNO) --> - SQL syntax error: the token ":" was not expected here
 - expecting LPAREN, found ':'
MIN(:(? - GIORNO)) --> - 1:25 - Open SQL syntax error: :PARAMETER not allowed
 - 1:26 - SQL syntax error: the token "(" was not expected here
 - 1:26 - expecting ID, found '('
Then I tried to avoid the MIN() function and I tried to do just the subtraction:
? - GIORNO --> - 1:21 - the arithmetic expression >>? - "GIORNO"<< contains a host variable (parameter marker)
:(? - GIORNO) --> - 1:21 - Open SQL syntax error: :PARAMETER not allowed
 - 1:22 - SQL syntax error: the token "(" was not expected here
 - 1:22 - expecting ID, found '('
'2007-09-24' - GIORNO --> - 1:34 - SQL syntax error: first argument of operator "-" must be a number, date/time or interval
 - 1:43 - SQL syntax error: arguments of operator "-" do not have correct types
 - 1:43 - SQL syntax error: derived columns in SELECT list with AS must be values
GIORNO - GIORNO --> - 1:21 - the group by list and the select list are inconsistent: the column >>"GIORNO"<< is neither grouped nor aggregated
 - 1:30 - the group by list and the select list are inconsistent: the column >>"GIORNO"<< is neither grouped nor aggregated
Why these parts of query are not accepted???
I don't understand why... I hope you can help me.

Problem writing a sql query for a select list based on a static LOV

Hi,
I have the following table...
VALIDATIONS
ID          Number     (PK)
APP_ID          Number
REQUESTED     Date
APPROVED     Date
VALID_TIL     Date
DEPT_ID          Number     (FK)
I have a search form with the following field item variables...
P11_DEPT_ID (select list based on dynamic LOV from depts table)
P11_VALID (select list based on static Yes/No LOV)
A report on the columns of the Validations table is shown based on the values in the search form. So far, my sql query for the report is...
SELECT v.APP_ID,
v.REQUESTED,
v.APPROVED,
v.VALID_TIL,
d.DEPT
FROM DEPTS d, VALIDATIONS v
WHERE d.DEPT_ID = v.DEPT_ID(+)
AND (d.DEPT_ID = :P11_DEPT_ID OR :P11_DEPT_ID = -1)
This query works so far. My problem is that I don't know how to do a search based on the P11_VALID item - if 'yes' is selected, then the VALID_TIL date is still valid. If 'no' is selected then the VALID_TIL date has passed.
Can anyone help me to extend my query to include this situation?
Thanks.

Hello !
Let's have a look at my example:create table test
id        number
,valid_til date
insert into test values( 1, sysdate-3 );
insert into test values( 2, sysdate-2 );
insert into test values( 3, sysdate-1 );
insert into test values( 4, sysdate );
insert into test values( 5, sysdate+1 );
insert into test values( 6, sysdate+2 );
commit;
select * from test;
def til=yes
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
def til=no
select *
from test
where decode(sign(trunc(valid_til)-trunc(sysdate)),1,1,0,1,-1)
       =decode('&til','yes',1,-1);
drop table test; It's working fine, I've tested it.
The above changes to my first idea I did because of time portion of the DATE datatype in Oracle and therefore the wrong result for today.
For understandings:
1.) TRUNC removes the time part of DATE
2.) The difference of to date-values is the number of days between.
3.) SIGN is the mathematical function and gives -1,0 or +1 according to an negative, zero or positiv argument.
4.) DECODE is like an IF.
Inspect your LOV for the returning values. According to my example they shoul be 'yes' and 'no'. If your values are different, you may have to modify the DECODE.
Good luck,
Heinz
