Object-relationa queries

Urgent! Object-Relational Query
Can I see objects created in Oracle 8.1.7 in Discoverer?
I using Discoverer 3.1 and I can't see the information stored in a object.
Any idea? The new versions of Discoverer works with object-relational database?
Thanks.
Alexandre.

hi priya,
if the info object contains data or not is not the point, u have to check whether the object is a data target or not.
all data targets are info providers.
data targets and info providers provide data to reports but info providers not hold data permanently where as data targets holds data permanently.
if u want to build queries on info object then u have to convert them as data targets,
goto RSA1 -> right click on info area -> click on insert char as data target -> give info object name.
after converting info object as data target u can build reports on that info object.
assign points if it helps,
thanks,
pavan.

A question about objects and queries

I just started using COM objects in ColdFusion. I am mostly
using CreateObject, but occasionaly use <CFOBJECT>
My question is; Do I have to destroy these object variables
when I am done? I know in a lot of other languages I work in, you
have to "clean up'" after yourself and destroy some variables when
you are done to avoid memory leaks. How does CF handle this?
While I am asking, what about queries? Do hey have to be
destroyed as well? What about queries made with QueryNew?
Thank you for the help.

Cold fusion cleans up for you.
You do not need to explicitly destroy anything unless threads
are spawned in a non standard way by Java or C code that you are
using.

Can Business Object Access Queries from the BI query designer?

Hi Gurus,
I've started working with BOBJ and honestly I'm not impressed with it's functionalities, specially with the report layouts (SO many limitations!!). Anyway I was wondering if Business Objects can access BI Queries in the Query Designer since I can do most of the manupilation in Query Designer that I need. Thank You in advance and any help will be most certainly appreciated.
- Kit

Hello KIT,
Also, look at the below Blog for xcelsius where he directly consumes the BEx query the QUERY_VIEW_DATA Web service out of the BW system. This is one way to approach the BEx query:

Transport objects and queries

Hi ,
I know that this topic has been discussed a lot, but can some one help me .
I have made some modifications to Infocube and query in Development system and now I would like to move them to QA and Production system in BI. Can some one tell me a step by step procedure to do this and how I should collect the path for the Infocube and the query to be passed on to the Basis people.
Thanks in advance
tanu

Hi,
Do the following.
1. Goto RSA1 -> Transport connection -> Under all object types -> Infocube -> select objects. There type in your Infocube name and select it and transfer to the right pane. Before transferring select the grouping option Data Flow before.
2. Create the above transport request and transport it to Production.
3. Create another Transport request for transporting the queries from RSA1 -> Transport connection -> Under all object types -> query elements -> query and select all the required queries.
Please note that while transporting make sure that all the objects are saved in Pacakage.
Hope this helps.
Best of luck.

Info Objects in Queries where (not) used

Hi Experts,
We're currently preparing migration from BW 3.5. to 70. I think this is a perfect opportunity for a clean up.
I want to start with info objects, especially their use in queries. so my question:
Is there a table (or tables) with the refernce of a query to info objects or vice versa?
I'd like to create a report, that shows e.g. all IOs not used in queries, how often used in queries and so on.
I checked tables like RSRREPDIR, RSZELTXREF etc., but without any success and I dare to doubt that there is a FM or a report provided by SAP.
Thanks in Advabce and Regards
Joe

Hi Pravender,
I could use sample code from related link
Where-used list of an attribute (either display or navigational)
as template for a report, what finally helped to fulfill my requirements mostly.
Thanks and Regards

Hi Tanu,
Go to Transport connection
You can create one request for changes in cube and one request for quries.
through SE09 you can transport it

Refreshing the screen using a View Object

Hi Experts,
Here is my requirement.
I have a View Object which queries the database and displays the results.
So I want to my VO to be executed when I click on Refresh button.
How can I achieve this?
Is there any example for this?
Thanks in advance

I think the mistake u did is populating the collection/entity of your custom view in some other place rather than on_new_focus method of the context class. So when u first time come to the view, it is calling your custom code and populating your custom view. But when u click new, it is not executing that method and it is not refreshing. on_new_focus is called everytime
you change to new or open in edit mode..that method should be declared as event handler method..
Move your code to the on_new_focus method of the particular context node. see standard codes how that is created and used...
e.g. you can see the component/view BT112H_SC/Details, context node BTPARTNERSET and method CREATE_BTPARTNERSET of CL_BT112H_S_DETAILS_CTXT of how it is used.

Urgent!! How to publish a session Info Object once and pass it to sevaral forms

Hi , I am using JDev 3.1. I have this problem when i create several forms in Jdev, where the wizard adds a sessionInfo object for each form. It also publishes them on the Infobus every time the form is called.I tried to use 1 marster sessionInfo Object from a marster form publish it there and then pass it to the other forms, but then the rowsets don't work propally. I f any one has any ideas please post as soon as possible.

We do have a FAQ, and the topic is part of the FAQ. Unfortunately, it seems that the FAQ is not yet available on OTN. In the meantime, I'll post some of the content here which may be useful:
<BLOCKQUOTE>quote:<HR>
Q
How do I share database information across multiple Frames?
A
This describes using a SDI with multiple frames that share common database information (for example, a master-detail application
based on Dept-Emp where Dept information is dispayed in one frame, and Emp in another). For help in constructing an MDI
application, please refer to the JDeveloper documentation.
1.Create an empty project
2.Add a class to this project (this class will contain the SessionInfo, RowSetInfo, AttributeInfo)
3.Switch to Design mode for this class, and create the SessionInfo and RowSetInfos for your application by selecting the
appropriate object from the Component Palette, then clicking in the Structure Pane.
4.Set the properties of these objects as normal.
5.Create an Application with an empty Frame
6.In design mode, drop the desired controls into the Frame.
7.You can set all the properties for these controls as usual except for the properties that bind the control to a datasource. To bind
the controls to a datasource, switch to Source mode and add the appropriate code, for example:
textFieldControl1.setDataItemName("infobus:/oracle/sessionInfo1/rowSetInfo1/Deptno");
8.Repeat steps 6 and 7 for the second Frame.
9.Modify the Application to instantiate the class that contains the database information, and optionally to display the second
Frame (you may want to use a button on Frame1 that shows Frame2 instead).
Note that if you wish to access the methods of the database information objects programmatically, you may need to make the objects
public static.
<HR></BLOCKQUOTE>
Also in regards to Ali's comment that executing all these queries when the app starts, you may be interested in the following:
<BLOCKQUOTE>quote:<HR>
Q
How do I delay the execution of one or more queries?
A
By default, all queries being used by RowSetInfos in your application are executed when SessionInfo.PublishSession() is invoked.
There are two methods to potentially improve the performance of your DAC application if your queries return a large number of
rows.
1) As a workaround, you can dynamically alter the Where clause of your queries so that fewer rows (or no rows) are retrieved
initially. For example, include the condition 1=2 in the Where clause. Then, based on some interaction from the user, you can set a
"real" where clause condition. For information on dynamically altering the Where clause, see the appropriate FAQ.
2) A slighter cleaner method is to delay the association and subsequent publishing of the RowSetInfo until AFTER
SessionInfo.publishSession() is invoked. The following illustrates the order in which the key steps would be performed:
1.define the all RowSetInfo objects and their attributes
2.parent any RowSetInfo whose queries should be executed immediately to the SessionInfo object
3.publish the SessionInfo
4.parent any RowSetInfo objects whose queries should be delayed to the SessionInfo object
5.when appropriate, publish the RowSetInfo using RowSetInfo.publishRowSet(true)
<HR></BLOCKQUOTE>
And, finally, the above makes reference to a FAQ for how to dynamically set the where clause:
<BLOCKQUOTE>quote:<HR>
Q
How do I dynamically alter the Where clause of a RowSet?
A
There are two ways to accomplish this task. You can either call the setWhereClauseCondition on the RowSet, or you can use bind
variables. Both of the samples below assume a TextField named textSearch in which the user has entered a search value.
void buttonSearch_actionPerformed(ActionEvent e) {
// Two ways of "refreshing" the RowSet with condition specified by user
// Note that both samples use AttributeInfo.getColumnName() to get the appropriate
// format of the column name which differs depending on whether the VO uses "Expert mode"
// Example using dynamically created condition
rowSetInfo1.setQueryCondition(NamerowSetInfo1.getColumnName() + " LIKE '" + textSearch.getText() + "%'");
// Example using bind variable in condition (Note that the VO and its associated views must use ? style parameters)
rowSetInfo1.setQueryCondition(NamerowSetInfo1.getColumnName() + " LIKE ?");
rowSetInfo1.setQueryConditionParams(new Object[] {textSearch.getText() + "%"});
// Execute the query in either case...
rowSetInfo1.executeQuery();
<HR></BLOCKQUOTE>
I hope this helps!!!

Mapping feature for queries that cannot be expressed using JDO QL

In the "Java Data Objects vs. Entity Beans" thread at theserverside.com,
there was a question concerning the ways to use a query that cannot be
expressed using JDO QL (for example SQL requests having no equivalent) .
Among the possibilities mentionned in his answers, Craig Russel said
that a JDO implementation could map an SQL query to a Java class
directly :
"This might be done by a JDO vendor who mapped a user-specified SQL
query to a JDO PC class. For example, if you have a DEPARTMENT table
that you want to write an aggregate query for "SELECT D.DEPTID,
MAX(E.SALARY) FROM DEPARTMENT D, EMPLOYEE E WHERE D.DEPTID = E.DEPTID".
You would map this query to a JDO PC class DepartmentMaxSalary which has
a key field deptid and a non-key field maxSalary. The key class
DepartmentMaxSalaryKey has a key field deptid.
Now, construct an instance of the key class:
DepartmentMaxSalaryKey dk = new DepartmentMaxSalaryKey(100);
DepartmentMaxSalary d = pm.getObjectById(dk);
System.out.println ("Department " + d.getDeptid()
+ " has max salary of " + d.getMaxSalary());
When the getObjectById is executed a hollow instance of
DepartmentMaxSalary is constructed by the PersistenceManager. When the
d.getMaxSalary() is executed, the implementation of the method accesses
the maxSalary field which causes the PersistenceManager to executes the
query and return the result into the field.
No implementation to my knowledge currently offers this kind of mapping,
but certainly some will in future."
Do you consider in providing this kind of mapping feature in Kodo ?
Thanks in advance.

Do you consider in providing this kind of mapping feature in Kodo ?Patrice,
Sorry for the delay responding to this question. The thread dropped out
of my awareness until Rakesh's followup question today.
We do not currently plan on providing a mechanism for configuring JDO
objects to load themselves from arbitrary SQL queries at this point. The
example above seems a little contrived, for a few reasons:
- Presumably, this aggregate salary object would be read-only.
Read-only JDO fields/objects are a whole separate topic that we
have chosen not to address just yet.
- Where would the complex SQL statement go? Putting it in the
metadata seems less than ideal, as this would make for a hideous
metadata file, and even more complexity and more debugging
problems than using direct JDBC SQL calls. Putting the SQL
statement into the class also seems awkward.
- Kodo provides a mechanism for obtaining a connection to the data
store. When aggregate info are needed or complex,
non-object-oriented queries must be executed, standard JDBC calls
to the data store are probably the most appropriate approach, as
they give you complete access to your data store.
If we see a significant interest in these capabilities, then we may
consider them for a future release.
Thanks in advance.Again, I apologize for the time delay in my response. I hope that this
answers your questions.

Possible to create presentation objects outside of JDeveloper?

Is it possible to create BI presentation objects (graphs, tables, crosstabs) outside of JDeveloper? I have been searching OTN forums, BI Beans javadoc and the OLAP API guide and have not found whether this is possible. I have seen where you can programatically create BI OLAP objects like queries and calculations, but not if/how you can create presentation objects.
Regards,
Steve Locke

Got it! I was able to extend the "New Presentation" sample to allow users to save their newly-created presentations back to the BI catalog. Here's how:
1) add a menu item for "Save"; add a listener for it
m_mnuSave = new JMenuItem("Save...");
m_mnuSave.setMnemonic('S');
fileMenu.add(m_mnuSave, 4);
m_mnuSave.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
mnuSave_ActionPerformed(e);
2) in mnuNew_ActionPerformed, add code to save the presentation to a module-level variable
Dataview dv = npw.getDataview();
m_objPresentation = npw.getDataview(); // new code
3) write the Save action handler
void mnuSave_ActionPerformed(ActionEvent e) {
String sName = "";
int result = 0;
if (m_objPresentation == null)
JOptionPane.showMessageDialog(null, "No presentation to be saved");
return;
/* Create InitialPersistenceManager */
InitialPersistenceManager pmRoot = (InitialPersistenceManager)getPersistenceManager();
/* Create PersistenceObjectChooser */
PersistenceObjectChooser dialog = new PersistenceObjectChooser(pmRoot);
JFrame frame = new JFrame();
result = dialog.showSaveDialog(frame);
if (result == PersistenceObjectChooser.OK_OPTION)
PersistenceManager pmCurrent = (PersistenceManager)dialog.getCurrentDirectory();
sName = dialog.getSelectedObjectName();
if (sName != null)
try
//if name is not bound, then rebind will bind it
pmCurrent.rebind(sName, m_objPresentation);
catch (Exception ex) {
showExceptionDialog(this, ex);
} // if sName != null
}// if result == OK_OPTION

Change objects in database

Hallo,
I've an oracle sqlj type, which implements the SQLData interface. To use it in a Java application, I use an other implementation of SQLData, which calls the methods of my oracle object via JDBC. So the functionallity is done in database.
In my java application, I get the database objects with queries like this and bind the results to my java class.
   SELECT objectX
   FROM tableX
   WHERE id = x;Now I want to call member procedures of my object type (which eventually are executed in database). These procedures change some of the attributes of my oracle type. According to the documentation, it is necessary to call an update statement in the server implementation, to write these changes to the database. The code could look something like this:
   PreparedStatement pstmt = conn.prepareStatement
    ("UPDATE tableX     SET objectX = ?    WHERE ID = x");
   pstmt.setObject(1, obj);   // obj is java representation of objectX
   pstmt.executeUpdate();So far it works fine. The problem is, that my oracle object itself must know about the query, it originates from. Is there any way, to update the changed object in database without this knowledge?
My ultimativ goal is a member procedure in the server implementation like this:
    void writeObject() {
       PreparedStatement pstmt = conn.prepareStatement
       ("UPDATE ?");
       pstmt.setObject(1, this);
       pstmt.executeUpdate();
    }I hope, my problem is clear and you have any ideas for me.
Thanks, Christian

Christian,
Are you aware of the JPublisher utility? Once you have types defined in the database, JPub can generate Java classes that map to the defined types. To learn more, check out the online doc at http://download-west.oracle.com/docs/cd/B10501_01/java.920/a96658/toc.htm.
There are many examples in the doc to give you better picture of how it works.

Technical names for objects within RSA1

Hi!
I cannot see in tcode RSA1 --> BI CONT --> Object Types --> Queries the technical names of the objects
When I search for 0TCT_MC21* as query, no results can be shown.
How can I change these settings in order to see the technical names of the objects as well?
Any helpful information will be very appreciated
Holger

Hi,
When you click on select objects there is an icon which says Technical Names on/off. This will show the objects with technicakl names.

Standard Query for Top 10 queries and Users

Hi Experts,
Is there any query which gives the details like ,
1. Top 10 queries executed in a month
2. Top 10 users ( By no of queries executed )
Regards,
Bhadri M.

1. Top 10 queries executed in a month
Use Query 0TCT_MCA1_Q0142.
In this report you will have to filter variable BI Object to Queries and also it gives stats for the last 30 days, you have have to remove the SAP User exit variable in case you do not want to use the 30 days option. And then you will have to define Condition for Top 10.
2. Top 10 users ( By no of queries executed )
Use Query 0TCT_MCA1_Q0141.
Similarly you have to modify this query.

Compare objects in Trasnsport Request

I would like to collect all the source system related objects from BW Development, and tranport it to BW QA client.
In BW Development, I have collected all the source system related object, and transport is created.
How can I compare and ensure that all the source system related objects are collected in the Transport request?
In SE10 ->Display the Transport Request, I can see there are some 2000 objects, but how can compare and ensure that there is other objects is missing?
please advise, thanks.

for such a huge package, this looks impossible to me. what you can do is use the transport connection, and collect your main objects (cube, queries,...). before and after as option. now when you have the list, you can check if there are still objects in $TMP or without a transport package...these objects are most likely not in your transport...
however, from my experience, i would say to consider transport from dev to qual as a trial and error phase...import the TR...if something is missing it will dump, indicating in the log what is missing...create a new TR in dev for these objects, transport to qual and reimport the big one again...and so on...till everything is correctly imported...
now execute process chains and afterwards reports to see that everything is running smoothly...
you might have dumps because objects are not activated, so you need to reimport activation
make sure you list the sequence of import...afterwards if you use the same sequence when going to prod, you should encounter no problem.
