Need result of expensive query

Hi All ,
I need a a query which will give the result of most expensive query i.e. whihc is taking most of I/O /memory.
Thanks

In addition to what sb has asked :
why not most network used?
But yes, if you wish to see Top SQL statements that are using the most resources then :
set long 9999999
set line 200;
column sql_text for a50
SELECT *
FROM (SELECT Substr(a.sql_text,1,50) sql_text,
Trunc(a.disk_reads/Decode(a.executions,0,1,a.executions)) reads_per_execution,
a.buffer_gets,
a.disk_reads,
a.executions,
a.sorts,
a.address
FROM v$sqlarea a
ORDER BY 2 DESC) WHERE rownum <= 10
And I think question has already answered at your's thread too :

I need return the result of a query on a stored procedure

I need return the result of a query on a stored procedure, I mean when I execute a stored procedure it returns a result set as a select query.
Best regards...

If you want some pl/sql code that can be used in a query as it were a table you may be interested in table functions:
SQL> create or replace type
2 t_emp is object (
3 name            varchar2(30),
4 hire_date date,
5 salary       number);
6 /
Tipo creato.
SQL> create or replace type
2 t_emptab is table of t_emp;
3 /
Tipo creato.
SQL> create or replace function tab_fun(p_dept in number)
2 return t_emptab is
3 e t_emptab;
4 begin
5    select t_emp(ename,hiredate,sal)
6      bulk collect into e
7      from emp
8     where deptno=p_dept;

How to execute a procedure depending on the result of a query?

Hello, I'm new in ODI.
I want to execute a procedure depending on the result of a query Oracle table.
We have a Oracle Table whit a column that contains two possibles values.
I want read the table, row by row, and depending on this value, execute a Procedure or execute another.
How can i do?

what you need to do is
1. create a variable which "new_var2" which has the count of the number of rows you want to process. must be data type numeric.
2. copy "new_var2" to the package screen.
3. duplicate the "new_var2" on the package screen and evaluate the variable and test for "> 0" zero, call it "new_var2_E"
3. create a new odi variable "new_var1" with a refresh of "select field1 fom (select field1,rownum as rownumber from tablex) where rownumber = #new_var2" in the relevant schema and technology.
4. copy "new_var1" into your package (some where in the flow)
5. right click the "new_var1" variable in you package screen and you should get the option duplicate step (click on that)
6. select the the duplicate "new_var1" on the package screen and correct the the name to something meaning full to you "new_var1_E", also change the "type" to "evaluate variable" then you should see a "value" box. enter one of the values you want to test in the box (remember do not put in quotes ' )
7. now back on the package screen join the "new_var1" to the "new_var1_E" with an OK line
8 you now join "new_var2" to "new_var2_E" with OK
9 you join "new_var2_E" to "new_var1"
10. you then join the "new_var1_E" with an OK or a KO line to the relevant procedure.
12. you need to duplicate "new_var2" in the package screen one more time this time and call it "new_var2_D" set the type to evaluate and then select the increment of -1
13. the relevant procedure to "new_var2_D" with an OK
14. join the "new_var2_D" to the "new_var2_E" with an OK
15. this should close off the loop now the exit point is "new_var2_E" with a KO line to the next part of your process....
Basically you should end up with a loop on new_var2 decementing, and it is used to get a specific next record row from your table.
Hope this helps, sorry it is a little long winded..

Weird result of oracle query before and after function base index creation

Hi All,
Here is the unique situation we are facing after creating just an index.
The query result before the index and the query result after the index do not match.
This is very illogical situation. Shidhar and me have done lot of R&D, also tried to get lots info from Google but we couldn't decipher the reason for that.
I am giving you all the details about the query, index and tables with following steps.
Please let us know if anything is going wrong from our side or is it a bug at oracle level which is a rarest possibility but a possibility.

Thanks

I just wanted to make a comment. The predicates in both your queries are flawed I believe. You convert a date column to a character and then you say only pick the converted result between two sets of characters.
TO_CHAR(TRAN_DATE,'YYYYMM') BETWEEN'200601'AND'200912'It should be coded like this for a proper date range comparison:
TRAN_DATE BETWEEN TO_DATE('200601','YYYYMM') AND TO_DATE('200912','YYYYMM')That will eliminate the need for you to create FBI that you created. You should now be able to create a regular (B*Tree) index on the TRAN_DATE column.
Also, now that we have the structure of your tables and sample data, what business question are you trying to answer? I think there is a better query that can be written if we know the requirements.
Hope this helps!

Can we use Result from another query in Webi using Bex uery universe?

Hi,
Can we use Result from another query filter option in Webi to create a report using a Bex Query universe?
I need to create a report using two universes, one is Bex Query Universe and the other is Orcle universe. I have two queries, one is using Oracle universe; the other using Bex Query universe. I need to pass the Oracle data from the Oracle query to the Bex Query query to get the matched data from SAP Bex query.
I used Result from another query in the query filter panel for the query using Bex query universe. But I got an error saying that 'A filter contains a wrong value. you cannot run this query. (Error: WIS 00007). The data used in the filter on both sides are the same. they are char.
I have tested by using two queries from the same Bex query universe to see if the Result from another query filter option works. And I got the same error.
Has anyone run into the same issue and if this is possible and what should be the solution?
Thanks in advance!
Edited by: BO_Haiyan on Oct 6, 2010 3:47 PM

In that situation:
Create two queries : Oracle and BW query.
@ Report:
As you have to see result set from both the Dataproviders, correct? To achieve thise one must have common dimension objects to merge them at report and use Objects those are coming from both queries to use them in single Table/Report.
Unless you don't use Merge Dimensions, you don't get a chane to use both queries objects in single Table/Report. (It will give tooltip saying: You can't drop here -- Incompatable Objects)
In case, if you don't have common dimensions, change object definitions to Detail objects, for those required.
Hope it helps you.
Thank You!!

Need Oracle Payroll SQL Query

Hello,
I need Oracle Payroll SQL Query with result:
First_name, Last_name, Payment_amount, Pay_date, Payroll_Frequency, Employement_status
Any Help would be greatful appreciated

You will need the following tales.
per_all_people_f, per_all_assignments_f,pay_run_results,pay_run_result_values
Query would e something like :
select papf.first_name,
         papf.last_name,
         prrv.*
From apps.per_all_people_f papf
         apps.per_all_assignments_f paaf
         apps.pay_run_results prr,
         apps.pay_run_result_values prrv
Where papf.person_id = paaf.person_id
and papf.business_group_id = paaf.business_group_id
and papf.current_employee_flag = 'Y'
and paaf.primary_flag ='Y'
and paaf.assignment_type = 'E'
and trunc(sysdate) between papf.effective_start_date and papf.effective_end_date
and trunc(sysdate) between paaf.effective_start_date and paaf.effective_end_date

SQ02 Infoset returns different results in SQ01 Query vs. Segment Builder TG

I want to get Segment Builder to use the same InfoSet and return the same results so, that I can then make a Target Group...but, I'm sure I'm missing some step along the way.
My SQ01 query returns 79 contact persons, but my segment builder only finds 42, none of which appear to actually be the Contact Person, but are in fact the Business Partner the Contact Person has a Relationship to.
I started by copying the CRM_MKTTG_BP_ADDR InfoSet and added the BUT051 table to it, which is when the SQ01 began returning the needed results.
I suspect the problem may be in the Master Group where I am using the B2B/B2C Program, but I don't know if that's the answer or not. I am not declaring an FM as I am using the BP-GUID in the data source, so I don't 'think' that's the issue...
Here's what I'm currently trying as my Data Source settings in case that will help:
Origin Type              03 InfoSet
RFC dest.
Name of InfoSet          ZCRM_MKTTG_BP_ADDR
Business Partner         BUT000-PARTNER_GUID
Function Module
Sampling InfoSet         ZCRM_MKTTG_BP_ADDR_SMP
Sample                   BUT000-PARTNER_GUID
Object
Partner Function
Description              Z BP Address
I already read every Segment Builder forum thread and the Sap Library on the subject, but either I missed something or there is a step not listed.
Anyone have any suggestions?

Solved!!
I was wrongly using AND/OR options to add filters in the segmentation tool...ups!

Results from another Query - not available

HI,
My environment is Business Objects XI 3.1 SP2 Edge series , i have below quereis with web Intelligence Reports
1. not available the functions/options Results from another Query(Any) or Results from another Query(ALL) at Query Level.
2. not getting list of Values for pronpt until i refresh values for prompt?
Please suggest me is there any fix packs available for the same to availle that functionality.
Best Regards,
Reddeppa K

not getting list of Values for pronpt until i refresh values for prompt?
There is option called "Automatic refresh before use" for the object properties available in the universe designer.
Please check the box for the object you are using for populating the list of values and export the universe.
not available the functions/options Results from another Query(Any) or Results from another Query(ALL) at Query Level.
There is a limitation for the query on query functionality that the both the queries can-not be from the OLAP universe.
I guess the query which needs to be filtered should be built on universe from the relational data base.

Rohit

Date Format (Need result in date format)

Dear ,
i have worked on this query which produce result in error, infact i need result in date format and this format 'MON-YY'. :
select to_date( EFFECTIVE_DATE,'MON-YY' ) as MON_YY FROM GL_JE_LINES
but now EFFECTIVE_DATE is like this format '12/31/2008'

I tell again: a date has no internal format.
There is only a default output-format for date-objects wich is used as default output format and for implicit date conversions.
If you want to know the actual nls_date_format for your session you can use:
select * from nls_session_parameters where parameter='NLS_DATE_FORMAT';You can change it for your session with:
alter session set nls_date_format='<your_new_date_format>';Please take a look at:

The internal storage of a date-object does not depend on the actual value of NLS_DATE_FORMAT.
This will only used for output and for implicit conversions e.g. with to_date or to_char without explicit format.
To select a date from a table is also an implicit conversion to character, because you want to see characters on your screen.

Issue with Results from Another Query (Error on Null value)

Hi All,
We have a WebI report using "Result from Another Query" option of BO XI R3.1. The report was running fine till recently the dimension object using result from another query had a null value. Report suddenly throwed error as the query filters are invalid.
Is there a way to make this filter optional if no data/null value is there ? Because we need those null values in report as well.
Thank you for your time.
Thanks & Regards

Hi Vivek,
It was not directly solved but I applied alternate logic to over come the issue.
Here's what I did to overcome:
I used a sub query in place of the whole result from another query.
For Ex:
Dim1 inlist result from another query1
I made it as
Dim1 inlist (Dim0)
where Conditions.
Here Dim0 is the object which we use for Result from another query and Conditions will be the necessary filter conditions to arrive proper Dim0. Make sure proper context is formed for the sub query.
Even though it resolved my problem, It introduces an new issue. It causes increase in query run time when huge set of data is returned from sub query.
Please let me know if i haven't explained clearly.
Hi Aris_BO,
Sorry for not responding earlier. The logic would probably make more queries null & not null. Thats why I was not advised to use it.
Thanks

Problem when Counting results of a query

Hi all
In our application, we use the Toplink Essentials Queryframework API to create queries because of JPA limitations.
Now I have a problem: I want to count the results of a existing query, i.e. I have a ReportQuery and I want to count the results of it.
I tried the following:
ReportQuery query = ...
ReportQuery countQuery = new ReportQuery(Pivot.class, builder);
countQuery.addCount(COUNT,
ExpressionBuilder.from("id", builder.subQuery(query)));
countQuery.setShouldReturnSingleValue(true);
return Integer.valueOf(session.executeQuery(countQuery).toString());
Now it seems that Toplink executes the query but the result is not correct, i.e. the count result is NOT the same as the number of results in the original query.
The subquery may contain group by's, a where clause and so on...
Anyone has an idea how to count the number of results of another query in Toplink?
It should have the same affect as a simple sql "select count(*) from (select ...)" query.
Regards
Michael

Not exactly sure what your doing, what does the original ReportQuery select?
You probably want to do something like the following:
originalQuery...
ReportQuery countQuery = new ReportQuery(Pivot.class, countBuilder);
countQuery.addCount("id");
countQuery.setSelectionCriteria(originalQuery.getSelectionCriteria());
You may need to also call rebuildOn() if you reuse the same selection criteria from a different query.
i.e.
countQuery.setSelectionCriteria(originalQuery.getSelectionCriteria().rebuildOn(countBuilder));

Need Help on below Query.

Hi All,
Need Help on below Query.
Consider,
"test9" Table Data in COLUMN "Name" AS
Name
=====
'a'
'b'
'c'
'd'
'e'
I am writing a query as :
SELECT * FROM test9 WHERE Name IN ('a','b','c','d','e','f','g')
I want result set as , It should show data as -
'f'
'g'
i.e. data which does not exists in the table and which is give in in clause
Is it possible in a single query.

You can put the data that is to be checked for into a table instead or an inline view, for example:
with t as
(select 'a' as c1 from dual
union all
select 'b' from dual
union all
select 'c' from dual
union all
select 'd' from dual
union all
select 'e' from dual)
select c1 from (select 'a' as c1 from dual
union all
select 'b' from dual
union all
select 'c' from dual
union all
select 'd' from dual
union all
select 'e' from dual
union all
select 'f' from dual
union all
select 'g' from dual)
minus
select c1 from t
C
f
g
2 rows selected.

Need result of expensive query
