Accessing all rows in Entity Object

Hi All,
I have a master-child relationship with ChildVO based on entity object. When user hits on save after making some changes, I would like to pass all rows in master view object and all fetched rows in entity object to a pl/sql api which takes pl/sql table datatypes. I would call this API in AM. So is there any way to access all entity rows of child view object?I tried to use view link accessors but it returns null. I can think of the following way:
for each row in master view object
loop
set current row for master view object. This would execute child vo for that master row.
then fetch all rows from child vo. populate pl/sql table
move on to next master vo row.
end loop;
Drawback with above approach is that we would excute child object query for every master row. Is there any direct way to access rows in entity object in AM? Any pointers on this would be of great help.
Thanks in advance,
Murari

"and all fetched rows in entity object"
is not a correct statement to make, EO will always represent a single row of the database record.you will get all the fetched rows in the VO, not the EO.

Is it possible to view all record of child object in parent detail page.

Hi All,
Could someone please tell me how to view all records of child object in any associated parent detail page.
For example, In opportunity detail page I want to see all lead associated with particular opportunity. As per standard setting I can be able to see only five lead records in opportunity detail page. Is it possible to view all lead on the same opportunity detail page instead of clicking on "show full list"
Thanks in advance.

View all rows

Hi,
I want to view all rows of a workbook in Discoverer Desktop but I can't. I have a worksheet where I can view 10000 rows. But when I select Sheet --> Count all rows the answer is 83165.
How can I view the rest of rows? I have the Sheet --> View all rows option disabled.
Thanks.

Hi there,
Look at Tools-->Options-->Query Governor. The "Limit retrieved date to" is set to 10,000. Change as required or de-select the option.

ADF: use of view link Accessor in Entity Object = always null?

Hi,
JClient 9.0.5.2, adf model.
I would like to use the view link accessor method in the master EO to retrieve detail EO values and the view link accessor method in the detail EO to retrieve master EO values.
Detail Rule:
In the detail EO an attribute is derived from an attribute of the master EO: detail attribute = master attribute.
Master Rule:
In the master EO an attribute is derived from the detail EO: master atribute set to 0 if detail EO exist else set to 0.
Tables:
Table Master => MasterEO => MasterVO
- masterPK (not updateable)
- masterField (not updateable)
- hasDetailsFlag
Table Detail => DetailEO => DetailVO
- detailPK (not updateable)
- masterPK => foreign key (not updateable)
- masterField (query only)
MasterDetailLink based on foreign key.
In link wizard I asked for the generation of following accessors in the source & destination Entity Objects:
In DetailEO accessor name: RetrieveFromMaster
In MasterEO accessor name: RetrieveFromDetail
In the DetailEO, I asked for the generation of the DetailEOImpl file, accessors and create method.
As wriiten in the file, before the create method:
** Add attribute defaulting logic in this method. **
I tought this is the place to retrieve the master attribute:
The code:
MasterVORowImpl masterVO = getRetrieveFromMaster();
if (masterVO == null)
System.out.println("MasterVORowImpl masterVO create NNNNNNNNNNNUUUUUUUULLLLLLLLLL");
The masterVO is always null?
I suppose I didn't understand something, my guest is that ViewObjects may not be used for default logic?
I know how to implement those rules in the database with triggers.
I think that the data I need for implementing those rules exist somewhere at the ADF level so retrieving the data from the db is not necessary?
Could somebody give some clues?
I didn't find a similar example in the Business Rules in BC4J document.
Your help will be appreciated
Frederic

Hi,
Detail Rule, copy attribute value form master.
In DetailEOImpl:
protected void create(AttributeList attributeList)
setAttribute(MASTERFIELD,this.getMaster().getMasterField());
super.create(attributeList);
Master rule, set flag to 0 if no details else set to 1.
In the MasterEOImpl added method to check if detail row exists based on Row Iterator => no db retrieval?
This method also sets the flag accordingly:
protected void checkHasOtherDetails()
oracle.jbo.RowIterator ri = this.getRetrieveFromdetail();
ri.last();
// last() must be called else hasNext() returns true even on last delete ???
Number hasDetails = Constants.NUMBER_NO; // = 1
if (ri.hasNext() || ri.hasPrevious())
hasDetails = Constants.NUMBER_YES; // = 0
if (!getHasDetailsFlag().equals(hasDetails)) {
this.setHasDetailsFlag(hasDetails);
I call this method in the remove method of the detailEOImpl:
public void remove()
this.getRetrieeFromMaster().checkHasOtherDetails();
super.remove();
To set the flag I added follwoing code in the create method of the DetailEOImpl:
protected void create(AttributeList attributeList)
setAttribute(MASTERFIELD,this.getMaster().getMasterField());
**** ADDED ***
Number masterHasDetailsFlag = getRetrieveFromMaster().getHasDetailsFlag();
if (!masterHasDetailsFlag.equals(Constants.NUMBER_YES)) {
getRetrieveFromMaster().setHasDetailsFlag(Constants.NUMBER_YES));
super.create(attributeList);
One more question:
Is there a danger of calling last() on row iterators in create/update/remove methods of *Impl files?
=> current row changed => any effect on display in JPanel
Thanks
Frederic

Filter rows in Entity Object Cache

Hi
Jeveloper version:Studio Edition Version 11.1.2.1.0
I have a table employees with columns employee_id, first_name, last_name, last_opr.
i have created entity object employees_eo. my entity cache should contain only rows which are not deleted(i.e last_opr not equal to 'D');
how do i achieve it.

I need to have only the rows which are not deleted(.e last_opr<>'D') in the entity object cache. (Not in the view object cache)
The reason why i need is: i have an alternate key in the entity object employees_eo with the combination of employee_id, department_id. it raises an error('already exists') when the same combination is found.
Lets say employee_id 100 with department_id 10 is deleted. Delete in the sense i am not deleting the record physically. Just flagging last_opr as 'D'.
When i am trying to add new record with employee_id 100 and department_id 10. it says 'already exists'.
so what i thought is , my entity object cache can contain only rows which are not deleted, so that alternate key will not check the deleted rows..

To implement the solution, please do:
1. Change instanceconfig.xml file in <biee11g_install>\instances\instance1\config\OracleBIPresentationServicesComponent\coreapplication_obips1 as following
<Views>
<Pivot>

<DefaultRowsDisplayedInDelivery>75</DefaultRowsDisplayedInDelivery>

HOWTO: Expose Entity Object Methods to Clients

By design, clients cannot directly access entity objects. The view object layer provides an extra layer of security--you can choose exactly what data and methods you want clients to see.
This HOWTO describes the process of exposing an entity object method to client programs.
First, if you don't already have one, you must base a view object on your entity object and add the view object to your data model. For full details of how to do this, see the help topics under
+Developing Business Components
--Working with View Objects, View Links, Application Modules, and Clients
+----Creating and Modifying View Objects, View Links, Application Modules, and Clients
For the purposes of this HOWTO, we'll assume that you already have an entity object, Employees, with a method on it, calculateBonus(),
and a view object EmployeesView based on Employees.
First, you must generate a view row class. A view row represents one row of the view object's cache; it corresponds to a view of a particular entity object.
To generate a view row class:
1. Right-click EmployeesView and choose Edit.
2. In the View Object Editor, select the Java page.
3. Select Generate Java File and Generate Accessors for the view row class.
4. Click Done. This creates a class called EmployeesViewRowImpl.
Next, you should add a "delegator" method to the view row class--a public method with the exact same signature as the entity method, that simply calls the entity method. For example:
public int calculateBonus(int rating) {
return getEmployees().calculateBonus(rating);
Next, you should export this method.
1. Right-click EmployeesView and choose Edit.
2. In the View Object Editor, select the Client Row Methods page.
3. Shuttle the method you just created into the Selected list and click Done.
This creates an interface called EmployeesViewRow that contains your method.
Now you can call the method from your client. You should cast the row returned by EmployeesView.current(), the <jbo:Row> tag, or a similar method or data tag to EmployeesViewRow.
For example,
<jbo:Row id="myRow" datasource="ds" action=Current>
<% out.println(((EmployeesViewRow) myRow).calculateBonus(3)); %>
</jbo:Row>
null

Hi Lisa,
There's a difference between exporting methods (on an application module, view object, and view row--this is done on the "Client Methods" tab of the view object and application module wizards and the "Client Row Methods" tab of the view object wizard) and making an application module remotable (which is done on the "remote" tab of the application module wizard).
You should always export methods you want clients to use--and you only need to do this on the application module if you've written methods on your application module (which I didn't in this HOWTO). You can still use these methods in local mode--the interfaces will be present locally. The advantage of exporting methods is that it doesn't lock you into local mode--you'll be able to change to remote mode later (if you decide that's the way to go) with minimal changes--because the interfaces will be present locally even when the implementation classes aren't.
By contrast, you should only make an application module remotable if you're planning on deploying in a non-local configuration. You can do this step right before deployment.
Hope this helps,
Avrom

How to read all rows stored in pojo bean from jsp page

Hi sir
After storing all rows into ArrayList object in pojo class, how to retrieve those rows from jsp page and display them together one by one.
Regards

Well, you wouldn't do it in Java. You would do it in JSTL, preferably.
So if your POJO had a getRows method which returned your List of row objects, you would get the list like this (after putting the POJO into request scope under the name of "pojo"):
${pojo.rows}
And if you wanted to go through that list and process each of the rows, then c:forEach would be the way:
<c:forEach value="row" items="${pojo.rows} />
(check the documentation, I'm posting this from memory)

Pushing committed rows in entity to all view objects

I have a Entity object EO1. I have two view objects VO1 and VO2, both based on EO1.
Assume User 1 and User 2 logged into the application.
User 1 -> creates one row in VO1 and commits the data.
User 2 -> he is viewing VO2, can he see the newly created (without re-executing the view object VO2). I mean the newly created row is pused to VO2 ? (is there any solution to resolve this?)

How to add row in multiple view object based on common entity object.

Hi ,
I have
Jdeveloper version - 10.1.3.3.0
Oracle Database - 11g R2
I have a situation where i have to show data from one table in three adf tables on jsf page depending on a flag value in a column in table. For this purpose i have done the following steps
a) Created an entity object on the database table .
b) Created three view objects on this entity object and edited the view object's SQL and included the where clause
                   WHERE A.USER_PERSONAL_NO = :P_USER_PERSONAL_NO AND
                       A.AUTH_TYPE = 'LF'
                   The auth_type cloumn decided in which view object the data will be shown
Now, when i query the data from database by executing the query of these view objects the data is shown correctly in all three view objects. Till here there seems every thing ok
Now , i have to provide the logic to add records in the adf tables for this i have provided add button in action facet of all three tables which are binded to methods in managed bean,
when i add a record in a adf table by add button the new row which is created is shown in all three tables . I cant understand why this is happening , please help me to solve this problem.
How can i make it possible so that the record appears only in that adf table in which the record is added.
The method for adding record is
            Row rw = currentAM.getWfRecommAuths().createRow();
            rw.setAttribute("UserPersonalNo",this.getQuery_personal_no().getValue());
            rw.setAttribute("AuthPersonalNo","");
            rw.setAttribute("AuthType","LX");
            currentAM.getWfRecommAuths().last();
            currentAM.getWfRecommAuths().insertRow(rw);
           Please help , thanks in advance.

Error while Insert new Row in Entity Base View Object

Hi,
can someone tell me the reason of following problem? :
There is a Entity Base View object, which is Binded as ADF Table in a JSFX Page.
I took the standard operations from the Control Panel: CreateInsert, Commit and Rollback.
Places them a ADF Buttons.
Whenever i am trying to insert a Row, after commit i am getting the ORA Error: ORA-01410: invalid ROWID.
By the way: The Entity Object is using the RowID as Primary Key.
When i press commit a second time, the the Row is inserted in the Database.
Any Idea, how to workarround this ORA Error?
Thank You!

n by default if you had no pkconstrainst in db,
in jdev default rowid as prim key.
as john said make the key as proper.
and do it.
if you have db constrainst in db.
it can be achived by dbconstrainstname with ora.
what am saying dbconstranist name will map it ora.

Two View Objects & One Entity Object

Has anyone ever had it where they create a row from a view object, set some attributes, insert it into that view object, and it shows up in another view object (as well as the one the row was actually inserted on)? Both of these view objects are using the same single entity object, it's just that their where clauses are slightly different. When I do a commit and then executeQuery, all is good and the new row only shows up in the intended view object.
Here is the code in my app module to do a row insertion on one of the view objects.
public void addQCNote(int userID, Number theStudyID, String theNote)
          try
               //StudyFtsViewObjImpl freeTextVO = getStudyFtsViewObj();
               StudyFtsQCOnlyViewObjImpl freeTextVO = getStudyFtsReadOnlyViewObj();
               freeTextVO.setWhereClauseParam(0, theStudyID);
               DBSequence freeTextTypeCode = null;
               StudyFTSQCCodeValueViewObjImpl freeTextCodeValue = getStudyFTSCodeValueViewObj();
               freeTextCodeValue.executeQuery();
               Row[] freeTextCodeValueCurrentRowArray = freeTextCodeValue.getAllRowsInRange();
               // There SHOULD only be one ... but if there is more, pick one - geeez.
               for (int i = 0; i < freeTextCodeValueCurrentRowArray.length; i++)
                    Row currentFTRow = freeTextCodeValueCurrentRowArray[0];
                    freeTextTypeCode = ((DBSequence) (currentFTRow.getAttribute(StudyFTSQCCodeValueViewObjRowImpl.CODEVALUE1)));
               Row freeTextRow = freeTextVO.createRow();
               // Sets up default values for insertion into db at commit time
               freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.PARENTENTITYID, theStudyID);
               freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.PARENTENTITYNAME, "STUDY");
               freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.FREETEXT, theNote);
               freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.FREETEXTTYPECD, freeTextTypeCode);
               freeTextRow.setAttribute(StudyFtsQCOnlyViewObjRowImpl.CREATEDID, new Number(userID));
               freeTextVO.insertRow(freeTextRow);
               freeTextVO.setCurrentRow(freeTextRow);
          catch (Exception ex)
               System.out.println("Exception in AR3MainAppModule.addQCNote: " + ex.toString());

Possible?Multi-Entity View Object with one Entity Object that is Read-only.

I know this sounds crazy, but I would like to create a multi-entity view object, where one entity object is based on a table in my application (we'll call it "Users", which basically stores the primary key for the person from the institutional people database), and the other table is a entity object based on a view of the institutional people database table (read only access), which we can call "People".
I know that since no updates will be done to the People table, it really should be a read-only View Object, but I would lose the ability to sort on attributes like Last Name, Hire date, etc, since those would be transient attributes in my ViewObject for the Users. By having People as an entity object, I can then create a multi entity view object and have the ability to join Users to People and be able to sort on the above mentioned fields (like Last Name).
The problem is that when I use the JDev (I'm currently using 10.1.2.1) AppModule BC4J tester, when I click on the multi-entity view object that I added to the AppModule it gives me an error:
oracle.jbo.RowCreateException) JBO-25017: Error while creating a new entity row for People.
----- LEVEL 1: DETAIL 0 -----
(java.lang.InstantiationException) null
I have tried to change all the attributes to updateable in my entity object, but no create method, and I have tried to make them all read-only, but no effect, I get the same error (probably because the People view is read-only in my schema).
Is there a way to change the entity object so that it will not try to create a new row when it runs the Tester? So that the multi entity view object behaves more like a view link, but gives me the added bonus of being able to sort on the Last Name column from the People table?
Thanks for any help on this subject...at worst, I will have to use the view link method to get the job accomplished, but it would be "cooler" if this would work!
Jeremy.

Steve, thanks for your quick response to my question.
To answer your questions, I was trying to create the Multi-entity View Object to give me more flexibility when working with my User table, and my People view. The flexibility I desired was that I would be able to sort my Users based on attributes in the People view. This is not possible when the there is only one Entity in my VO, and the People view data are all transient attributes, because they are not in the SQL statement.
Ultimately, after working with one of my colleagues, we decided to use the approach that you mentioned by creating a read-only VO with the SQL query we want to display to the user (contains both User and People data fields), and then use a different ViewObject when performing other actions on the User Table (such as inserts/updates/deletes). By using the setWhereClauseParam() method in the handleLifeCycle() for the JSP page, we should be able to navigate between the different View Objects, so that the user does not see any difference.
Thanks! Oh, and by the way, I have read your article you included before, and I have used it many times before to tune my View Objects! Thanks!
