5- 6 Measure Objects in A Single Query
Hi Techies,
I want to see the consolidated value of the measure object's of my universe,
when I place my measure objects(6) in the single query, with a conditional object and wen I run the query I am seeing an error message as no data to retrieve.
and If I take one measure object in each query I am able to see some data, is there any reason behind this ..
can't I proceed with single query with all my measure objects in the same query rather than many data providers for each measure object.
Please suggest me on this
Thanks in advance .............
All the measure objects are coming from single table only,
and the conditional object means we have written some condition at universe level and these objects refer to another table and there is a necessary join between these two tables...

Drill function implemented on Measure object column in the webi report
Post Author: madan kumar
CA Forum: WebIntelligence Reporting
Hi,
I have a small issue in my project.(Maintenance Project)I created a measure object in the fact table of the existing universe and saved and exported to the repository. (Say Measure object is D where D = A-(B+C))I inserted the same object as a column between two measure objects columns of a existing WebI report.
The report has two hierarchies involved - each hierarchy has dimension objects involved.I have checked with the hierarchies to make sure that measure object is not involved.The scope of analysis is None for the query.Version is BO XI R2.
The issue is the Drill function is implemented on that particular new column.The drill function should be applicable only to the two dimension objects involved in the report.But this measure object column is also getting drilled once the Drill option is selected.I had to remove the drill optiion from the Measure object column.
Can anyone help me on this issue...
Thanks in advance...

Thanks for your reply. I did the date diff on the columns. It does not break into 3 different groups. I am using a function called previous on the date column. So the report is like this
DATE Pervious (DATE) Date - Pervious(DATE)
01-01-2008 01:06 Null
01-01-2008 01:12 01-01-2008 01:06 :06
01-01-2008 01:18 01-01-2008 01:12 :06
01-01-2008 01:24 01-01-2008 01:18 :06
01-01-2008 01:30 01-01-2008 01:24 :06
01-01-2008 01:36 01-01-2008 01:30 :06
Basically we are breaking on the Date - Previous ( Date) column which does not work. I am not sure if there is a way to break this. I even tried it in Crystal REports XI and it does not work their either. Any help with this issue with be greatly appriciated.

How to measure the performance of sql query?
Hi Experts,
How to measure the performance, efficiency and cpu cost of a sql query?
What are all the measures available for an sql query?
How to identify i am writing optimal query?
I am using Oracle 9i...
It ll be useful for me to write efficient query....

I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
OBJECT_NAME,
CARDINALITY,
LAST_OUTPUT_ROWS,
LAST_CR_BUFFER_GETS,
LAST_DISK_READS,
LAST_DISK_WRITES,
FROM V$SQL_PLAN_STATISTICS_ALL P,
(SELECT *
FROM (SELECT *
FROM V$SQL
WHERE SQL_TEXT LIKE '%findme%'
AND SQL_TEXT NOT LIKE '%V$SQL%'
AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
ORDER BY LAST_LOAD_TIME DESC)
WHERE ROWNUM < 2) S
WHERE S.HASH_VALUE = P.HASH_VALUE
AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:

How to calculate the area of a large number of polygons in a single query
Hi forum
Is it possible to calculate the area of a large number of polygons in a single query using a combination of SDO_AGGR_UNION and SDO_AREA? So far, I have tried doing something similar to this:
select sdo_geom.sdo_area((
select sdo_aggr_union ( sdoaggrtype(mg.geoloc, 0.005))
from mapv_gravsted_00182 mg
where mg.dblink = 521 or mg.dblink = 94 or mg.dblink = 38 <many many more....>),
0.0005) calc_area from dualThe table MAPV_GRAVSTED_00182 contains 2 fields - geoloc (SDO_GEOMETRY) and dblink (Id field) needed for querying specific polygons.
As far as I can see, I need to first somehow get a single SDO_GEOMETRY object and use this as input for the SDO_AREA function. But I'm not 100% sure, that I'm doing this the right way. This query is very inefficient, and sometimes fails with strange errors like "No more data to read from socket" when executed from SQL Developer. I even tried with the latest JDBC driver from Oracle without much difference.
Would a better approach be to write some kind of stored procedure, that adds up all the single geometries by adding each call to SDO_AREA on each single geometry object - or what is the best approach?
Any advice would be appreciated.
Thanks in advance,

I am now trying to update all my spatial table with SRID's. To do this, I try to drop the spatial index first to recreate it after the update. But for a lot of tables I can't drop the spatial index. Whenever I try to DROP INDEX <spatial index name>, I get this error - anyone know what this means?
Thanks,

How can i fetch records from 3 tables in a single query without using join
Hi.
Can any body please tell me <b>How can i fetch records from 3 tables with a single query without using joins</b>
Thanx
prabhuduttaHi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.

Group by function in a measure object
Hi All,
I am trying to create a measure in universe which is the sum of ticket amount group by country. like,
sum(Payments.Ticket_Amount) group by country name. When i place this measure in a report group footer it should display the sum to that particular group. But it is not working.
Could anybody help me how to write a group by function to create a measure.
Thanks,
swati.Hi swati.
You don't need to write the GROUP BY statement at the universe level.
The universe knows that aggregate functions require group by statements and will group the aggregate measure objects by whatever dimension objects are included in the query. If you have a measure object that is not based on an aggregate but has a projection of Sum, it will only be aggregated at the report level once the data has been returned by the query.
Measure: sum(sales_fact.value)
Measure: sales_fact.price
Dimension: country_dim.country
This would generate SQL along the lines of:
SELECT sales_fact.price, country_dim.country, sum(sales_fact.value)
FROM sales_fact, country_dim
WHERE sales_fact.country_key = country_dim.country_key
GROUP BY sales_fact.price, country_dim.country
Hope that clears it up for you.

Need different rows from single query based on condition
Hi,
I have a table with 100 rows that holds employees and their roles.
I need to write a SQL(not a PL/SQL block) as below
1. When employee with role 'VP' logs in, the query should return all the 100 rows.
2. When employee with role 'MGR' logs in, the query should return only those rows whose MGR is the logged in employee.
3. When employee with role 'SALE_EXEC' logs in, it should return single rows corresponding to this SALE_EXEC.
My requirement here is to get these outputs from a single query.
Can anyone please help me with this.

New Policy Groups
When adding the policy to a table, view, or synonym, you can use the DBMS_RLS.ADD_GROUPED_POLICY interface to specify the group to which the policy belongs. To specify which policies will be effective, you add a driving context using the DBMS_RLS.ADD_POLICY_CONTEXT interface. If the driving context returns an unknown policy group, then an error is returned.
If the driving context is not defined, then all policies are executed. Likewise, if the driving context is NULL, then policies from all policy groups are enforced. In this way, an application accessing the data cannot bypass the security setup module (which sets up application context) to avoid any applicable policies.
You can apply multiple driving contexts to the same table, view, or synonym, and each of them will be processed individually. In this way, you can configure multiple active sets of policies to be enforced.
Consider, for example, a hosting company that hosts Benefits and Financial applications, which share some database objects. Both applications are striped for hosting using a SUBSCRIBER policy in the SYS_DEFAULT policy group. Data access is partitioned first by subscriber ID, then by whether the user is accessing the Benefits or Financial applications (determined by a driving context). Suppose that Company A, which uses the hosting services, wants to apply a custom policy which relates only to its own data access. You could add an additional driving context (such as COMPANY A SPECIAL) to ensure that the additional, special policy group is applied for data access for Company A only. You would not apply this under the SUBSCRIBER policy, because the policy relates only to Company A, and it is more efficient to segregate the basic hosting policy from other policies.
How to Implement Policy Groups
To create policy groups, the administrator must do two things:
Set up a driving context to identify the effective policy group.
Add policies to policy groups as required.
The following example shows how to perform these tasks.
Note:
You need to set up the following data structures for the examples in this section to work:
DROP USER finance CASCADE;
CREATE USER finance IDENTIFIED BY welcome2;
GRANT RESOURCE TO apps;
DROP TABLE apps.benefit;
CREATE TABLE apps.benefit (c NUMBER);
Step 1: Set Up a Driving Context
Begin by creating a namespace for the driving context. For example:
CREATE CONTEXT appsctx USING apps.apps_security_init;
Create the package that administers the driving context. For example:
CREATE OR REPLACE PACKAGE apps.apps_security_init IS
PROCEDURE setctx (policy_group VARCHAR2);
END;
CREATE OR REPLACE PACKAGE BODY apps.apps_security_init AS
PROCEDURE setctx ( policy_group varchar2 ) IS
BEGIN
REM Do some checking to determine the current application.
REM You can check the proxy if using the proxy authentication feature.
REM Then set the context to indicate the current application.
DBMS_SESSION.SET_CONTEXT('APPSCTX','ACTIVE_APPS', policy_group);
END;
END;
Define the driving context for the table APPS.BENEFIT.
BEGIN
DBMS_RLS.ADD_POLICY_CONTEXT('apps','benefit','APPSCTX','ACTIVE_APPS');
END;
Step 2: Add a Policy to the Default Policy Group.
Create a security function to return a predicate to divide the data by company.
CREATE OR REPLACE FUNCTION by_company (sch varchar2, tab varchar2)
RETURN VARCHAR2 AS
BEGIN
RETURN 'COMPANY = SYS_CONTEXT(''ID'',''MY_COMPANY'')';
END;
Because policies in SYS_DEFAULT are always executed (except for SYS, or users with the EXEMPT ACCESS POLICY system privilege), this security policy (named SECURITY_BY_COMPANY), will always be enforced regardless of the application running. This achieves the universal security requirement on the table: namely, that each company should see its own data regardless of the application that is running. The function APPS.APPS_SECURITY_INIT.BY_COMPANY returns the predicate to make sure that users can only see data related to their own company:
BEGIN
DBMS_RLS.ADD_GROUPED_POLICY('apps','benefit','SYS_DEFAULT',
'security_by_company',
'apps','by_company');
END;
Step 3: Add a Policy to the HR Policy Group
First, create the HR group:
CREATE OR REPLACE FUNCTION hr.security_policy
RETURN VARCHAR2
AS
BEGIN
RETURN 'SYS_CONTEXT(''ID'',''TITLE'') = ''MANAGER'' ';
END;
The following creates the policy group and adds a policy named HR_SECURITY to the HR policy group. The function HR.SECURITY_POLICY returns the predicate to enforce security on the APPS.BENEFIT table:
BEGIN
DBMS_RLS.CREATE_POLICY_GROUP('apps','benefit','HR');
DBMS_RLS.ADD_GROUPED_POLICY('apps','benefit','HR',
'hr_security','hr','security_policy');
END;
Step 4: Add a Policy to the FINANCE Policy Group
Create the FINANCE policy:
CREATE OR REPLACE FUNCTION finance.security_policy
RETURN VARCHAR2
AS
BEGIN
RETURN ('SYS_CONTEXT(''ID'',''DEPT'') = ''FINANCE'' ');
END;
Create a policy group named FINANCE and add the FINANCE policy to the FINANCE group:
BEGIN
DBMS_RLS.CREATE_POLICY_GROUP('apps','benefit','FINANCE');
DBMS_RLS.ADD_GROUPED_POLICY('apps','benefit','FINANCE',
'finance_security','finance', 'security_policy');
END;
As a result, when the database is accessed, the application initializes the driving context after authentication. For example, with the HR application:
execute apps.security_init.setctx('HR');
Validating the Application Used to Connect to the Database
The package implementing the driving context must correctly validate the application that is being used to connect to the database. Although the database always checks the call stack to ensure that the package implementing the driving context sets context attributes, inadequate validation can still occur within the package.
For example, in applications where database users or enterprise users are known to the database, the user needs the EXECUTE privilege on the package that sets the driving context. Consider a user who knows that:
The BENEFITS application allows more liberal access than the HR application
The setctx procedure (which sets the correct policy group within the driving context) does not perform any validation to determine which application is actually connecting. That is, the procedure does not check either the IP address of the incoming connection (for a three-tier system) or the proxy_user attribute of the user session.
Such a user could pass to the driving context package an argument setting the context to the more liberal BENEFITS policy group, and then access the HR application instead. Because the setctx does no further validation of the application, this user bypasses the normally more restrictive HR security policy.
By contrast, if you implement proxy authentication with VPD, then you can determine the identity of the middle tier (and the application) that is actually connecting to the database on behalf of a user. In this way, the correct policy will be applied for each application to mediate data access.
For example, a developer using the proxy authentication feature could determine that the application (the middle tier) connecting to the database is HRAPPSERVER. The package that implements the driving context can thus verify whether the proxy_user in the user session is HRAPPSERVER. If so, then it can set the driving context to use the HR policy group. If proxy_user is not HRAPPSERVER, then it can disallow access.
In this case, when the following query is executed
SELECT * FROM APPS.BENEFIT;
Oracle Database picks up policies from the default policy group (SYS_DEFAULT) and active namespace HR. The query is internally rewritten as follows:
SELECT * FROM APPS.BENEFIT WHERE COMPANY = SYS_CONTEXT('ID','MY_COMPANY') and SYS_CONTEXT('ID','TITLE') = 'MANAGER';
How to Add a Policy to a Table, View, or Synonym
The DBMS_RLS package enables you to administer security policies by using its procedures for adding, enabling, refreshing, or dropping policies, policy groups, or application contexts. You need to specify the table, view, or synonym to which you are adding a policy, as well as the data pertinent to that policy, such as the policy name. Such data also includes names for the policy group and the function implementing the policy. You can also specify the types of statements the policy controls (SELECT, INSERT, UPDATE, DELETE, CREATE INDEX, or ALTER INDEX).

Updating multiple node in a single query
Hi
Shall I update multiple nodes (which satisfies the given condition) in a single query? From the prototype we suspect that all nodes in all document are not updated in the container.
Version: BDB XML 2.4 - Fedora core 4 Linux - C++ language
Query:
replace value of node collection()/File[@Id="57565C01327A"]//Entry[@Class="Measurement" and @Id="0"]/Attribute[@Name="apDlBhUtil"]/@Value with 8'
Result:
XmlException occurred with msg 'Error: Sequence does not match type node() - the sequence contains more than one item [err:XUTY0008], <query>:1:1'
We have tried running the query in both Lazy and Eager evaluation type. Please clarify that the issue is with the query/execution type or BDB XML doesn't support this feature?
Thanks
SanthoshSanthosh,
Try:
for $i in collection()/File[@Id="57565C01327A"]//Entry[@Class="Measurement" and @Id="0"]/Attribute[@Name="apDlBhUtil"]/@Value return replace value of node $i with 8'The problem with your original is that the argument for "replace value of" needs to be a single item, not a sequence.

How to use multiple hierarchies for a single char in single query
Hi,
Is there any way that we can use multiple hierarchies for a single char in single query. I tried and it just allows me to select one hierarchy even if I use hierarchy variable.
I have a requirement where user wants to see information related to a cost center with different cost center groups in different hierarchies (every year has different cost center group hierarchies).
Suppose I want to see information related to a cost center from year 2001-2004.in these four year cost center may have been associated to different groups depending upon that year hierarchy. How can I do that?
Thanks
JonaNope. Now way to do this.
There is always just one hierarchy assigned to a characteristic. And even if the hierarchy was time dependent, it only reads it for one key date and not according to transaction data.

Multiple databases in a single query
I need to query multiple databases in a single query.
e.g.
Database d1 contains table t1 with column id
Database d2 contains table t2 with column id
I need a query like
SELECT * FROM t1, t2 WHERE t1.id = t2.id;
is this possible in jdbc? if yes can anyone help with some sample code?
thanks,
Ashish SarafIt is not possible using the JDBC API to query tables in two or more databases using a single query. The reason is that a JDBC Connection is made to a single data source.
However, some databases support the idea of federations or linked tables. What you do is inside the database manager link or federate a table that is present in another DBMS. Then, pose a single JDBC query to the one DBMS which will have its own table and links to the external tables.
Another approach is to use a special JDBC driver with a built-in integration engine that will perform a query across multiple databases. In effect, the system poses separate queries to the different databases and integrates and joins the data together for you automatically on the client-side. That is much easier than doing it yourself in code, but that is also possible for simple queries.
As part of my research program, we have released a shareware version of the UnityJDBC driver that can query multiple databases using a single SQL query. For more information, see:

Populate Multiple Items bundled in a single query
Hello,
I am trying to create a report in which I have mulitple items that I want to populate. All of these use the same query but use different rows in the query to populate themselves. My question is:-
Is there a way to bundle the item assignment into a single query and populate the items from there? I want to reduce the time it takes for me to display the report and just hit the database once instead.Hi there,
when u say report, i think its a more of a page showing few items on a region whose values are populated from Database rather than a SQL report which will not have any items. Is that correct?
yes, multiple items of a page can be assigned values at once.
assume: P1_ITEM1,P1_ITEM2,P1_ITEM3,P1_ITEM4 are different items on a page, an "On-Load Before Header" PL/SQL process can be created to assign values to the items in this way:
SELECT tab.col1,tab.col2,tab.col3,tab.col4 INTO :P1_ITEM1,:P1_ITEM2,:P1_ITEM3,:P1_ITEM4 FROM TABLE tab;
Item "Source Used" should be of type: Only When Current Value in session state is null
Source Type: PL/SQL Expression or function
and Source Value or EXpression should be some thing like this :P1_ITEM1
Hope this helps.

1. with below query I am finding which student_id had most marks in any 3 successive quizes (see the 3-1 part below) in the query..

15 rows selected.With above query, I can play around and find for any 'n' number of consecutive quizes, like marks in 2 consecutives quizes, 3, 4 and so on but for each 'n' value I've to run a seperate query mentioning (2-1) or (3-1) or (4-1) and so on..
since my table is big and there are about 400 quizes so what I want to find out is for each 'n' consecutive quiz (from 1 to 400) which student had most marks for each consecutie 'n' quiz. Like in 1 (consecutive) quiz which student had the highest marks and then 2 conseuctive quiz who had most marks and then in 3 consecutive quiz who had most marks and so on till 400 consecutive quiz who had most marks... rather than running query for each 'n' value seperately i want a single query that can give me a summary of most marks in each n consecutive quizes...
my sample output is:
Nth consecutive quiz student_id sum(marks)
1 1 90
2 1 170
3 1 246
4
100
200
300
400 ? ? Is this possible to get the above output from one single query? If there are two or more students with equal most marks for any 'n' conseutive quizes then both should come in the summary.
Hope I have been able to put up my question clearly.

Is it possible to combine 2 different reports in a single Query?
Dear All,
What am I working at?
I produced a Query for Debtors Aged Analysis which mimics the Official SAP B1 8.8 Aging Report.
It ages the outstanding invoices by Posting Date ( RefDate in JDT1)
I also made another Report which ages outstanding amounts by Document Date simply by replacing all RefDate by TaxDate
They give different answers if Posting Date is different from Document Date, e.g a manual invoice dated 5 Jun 2011 is posted on 2 Jul 2011.
What I want to do?
My idea is to produce a SINGLE QUERY which will generate either Aging depending on settings:
(a) A Debtors Aging by Posting Date
(b) A Debtors Aging by Document Date
I declare 2 variables:
(a) @refdt is [%1] and represents Posting Date (JDT1 RefDate)
(b) @taxdt is [%2] and represents Document Date (JDT1 TaxDate)
When the Query is run, the foll dialog appears:
Query - Selection Criteria
Posting Date Equal .......
Document Date Equal .......
OK Cancel
We are expected to fill in only 1 date and leave the other blank, and Query will generate the required report .
What is my problem?
Query runs smoothly, but amounts in the Balance column does not get analyzed in the Age brackets: Current / 1 Mth Ago / etc
I think I know where's the problem
I am assuming (wrongly) that if we don't fill one date field, the query returns NULL for that variable. In fact, it appears to return GetDate().
Help
Can anybody help me put the correct commands so that all my balances are correctly analysed in the respective age buckets?
Thanks
Leon Lai
