ADF Intersection table / create intersection rows

Good morning everybody,
can anyone help me with the task of using a intersection table (Many-to-Many relationship between A and B) with ADF BC ?
This is my database design:
TABLE A
ID (PK)
TABLE X (intersection table)
TableA.ID (PK)(FK)
TableB.ID (PK)(FK)
Number n (PK)
TABLE B
ID (PK)
I have a new bounded task flow, a dialog (2 pages), which first allows the user to create an A-object.
The next step is to create B-Objects which belong to the A-Object.
Then the user can commit or add more new B-objects to the A-Object.
I have created alle the entity objects and view objects via the assistant of "new business components from tables" which created:
Entity A
Entity X
Entity B
X Assoc Fk1
X Assoc Fk2
VO A
VO X
VO B
VL Fk1
VL Fk2
My task flow does this :
1. create new VO-A (via Create with parameters)
2. view activity CreateA
3. create new VO-B (via Create with parameters)
4. view activity CreateB
from this activity you can commit transaction or go back to 3. to add more VO-Bs.
So, how is it possible to handle the intersection table ?
I read something about "intersection associations and intersection view links" but some people say in this context, that you dont need it (all what is build by the assistant from the tables is ok). Sorry, but this made me very confusing :-/
Some guys recommended to create one VO which contains alle three entities (A,X,B).
First thought was, to handle all this business logic (create new VO-X and use setter to the FK/PK IDs...) in the managed bean, but this would be very dirty... There should be a way of doing this automatically...
I am very new to ADF and would be very happy, if anyone could help me!
Thanks in advance,
best regards
Marcus

Hi John,
my question is, how can I insert new rows to a intersection table ?
Is there a declerative way or do I have to write code ?
As I described before, I have two views as a bounded task flow. In the first view the user creates a new Object-A and in the second view the user creates an Object-B.
Before each view is started, I create the correspondent VO via CreateInsert declerative, so my views shows the empty row (all its attributes to fill out).
Thank you very much,
Marcus

Creating an intersection table record

I want to add an intersection table record and the related FK record at the same time. I have three tables with cardinality shown below:
Restaurants 1:N RestaurantRatings 0..1:1 Ratings
Thus, a restaurant can have zero or more customer ratings (i.e. restaurant reviews).
We use an intersection table (i.e. "RestaurantRatings") because table "Ratings" is also used for rating food items, which involves another intersection table (not mentioned above) to keep track of the food
ratings.
I followed the instruction in the ADF Developers Guide 11g Release 1 (11.1.1) for the following sections:
38.8 Controlling Entity Posting Order to Avoid Constraint Violations
39.9 Creating a View Object with Multiple Updatable Entities
Per section 38.8, I created the following override of EO method RestaurantRatingsImpl::postChanges for intersection table RestaurantRatings.
public void postChanges(TransactionEvent e) {
//If current entity is new or modified
if (getPostState() == STATUS_NEW ||
getPostState() == STATUS_MODIFIED)
//Get the associated restaurant for this intersection-table row
EntityImpl restaurants = this.getRestaurants();
//If there is an associated restaurant
if (restaurants != null)
//And if it's post-status is NEW
if (restaurants.getPostState() == STATUS_NEW)
* Post the restaurant first, before posting this
* entity by calling super below
restaurants.postChanges(e);
EntityImpl rating = this.getRatings();
//If there is an associated rating
if (rating != null)
//And if it's post-status is NEW
if (rating.getPostState() == STATUS_NEW)
* Post the rating first, before posting this
* entity by calling super below
rating.postChanges(e);
super.postChanges(e);
Then I use RestaurantRatingsViewLink, in the "Oracle Business Component Browser", to create a new Ratings record that is linked to an existing Restaurants record. My debugging session reveals that line
"this.getRatings();" returns null when I create a new Ratings record.
Any ideas, or better examples for how to properly create an intersection table record or update a view object with multiple entities objects.
Thanks,
Travis

Setting Composition on RestaurantRatingsRatingFk1Assoc didn't fix the problem. This association defines "Ratings.id" as the source and "RestaurantRatings.RatingId" as the destination.
Using the Oracle Business Component Browser, I attempted to insert a new row in the ResataurantRatings intersection table. I get the following error:
(oracle.jbo.AttrValException) JBO-27014: Attribute RatingId in AppModule.RestaurantRaitingsView1 is required.
I suspect we can't use composition because we have two associations from intersection table "RestaurantRatings". That is, table "RestaurantRatings" has two foreign keys. One to table "Restaurants". The other to table "Ratings".
Our RestaurantRatingsView has "Restaurant" as the master EO and "Ratings" as the detail EO. They are both set as "Updatable" in the view's "Entity Objects" tab.
Is composition really usable in this situation? Is there a similar example?

How do I Create a Tabular Form for an Intersection Table

Situation
There are three tables involved (PROJECT, STAFF, TASK)
PROJECT(PROJECT_ID, PROJECT_NAME)
STAFF(STAFF_ID, STAFF_NAME)
TASK(PROJECT_ID, STAFF_ID, HOURS)
There is a many to many relationship between PROJECT and STAFF. The intersection table is TASK.
Issue
I would like to create a tabular form for the TASK table. I would like to be able to click on a button (Add Row) to add a row to the existing tabular form. The row will have a LOV for the PROJECT_ID (showing PROJECT_NAME) and one for the STAFF_ID (showing STAFF_NAME) and a free form text field for the hours.
I've tried a bunch of different ways but am unable to acheive this functionality. I must be doing something wrong. This sort of thing is trivial.
Any guidance/suggestions are greatly appreciated.
Thanks

Adding a new surrogate key column to an existing table is not that big a deal.
alter table t add (pk int primary key);
create a before-insert row-level trigger to populate the key;Other than that, you are out of luck w.r.t the wizards. Yes, you can define a 2nd PK column in the wizard, but then the 2 PK columns becomes read-only (but you want to update them).
You can write your own tabular form using htmldb_item APIs and your own after submit processes to process the updates. See the manual Tabular Form Howto in the documentation.
Thanks

Querying multiple intersection tables against another table for row exists

Hi all,
Running on:
Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production
With the Partitioning and OLAP options
JServer Release 9.2.0.8.0 - Production
I am setting up email subscription service for news service website. News articles are tagged with multiple audiences, topics, regions and departments. Legacy data model we're dealing with implements one intersection table (M:N) for each of audience, topic, region and department lookup table and main news article table.
Email subscribers can pick any combination of the above options (audience, dept etc..) to customize the content of their email. Emails will be either daily or weekly digests of articles of interest, based on their chosen options.
The subscriber options are captured in one table, each option type being its own column. I'm trying to write one query to basically extract all articles that match a given subscriber's chosen options.
create table audiences(articleid number, audienceid number);
create table topics(articleid number, topicid number);
create table regions(articleid number, regionid number);
create table depts(articleid number, deptid number);
create table subscriber_options(emailid number,audienceid number,topicid number, regionid number, deptid number);
insert into audiences(articleid,audienceid)
SELECT
ceil(dbms_random.value(1,10)),
ceil(dbms_random.value(1,50))
from all_objects where rownum < 100;
insert into topics(articleid,topicid)
select
ceil(dbms_random.value(1,10)),
ceil(dbms_random.value(1,50))
from all_objects where rownum < 100;
insert into regions(articleid,regionid)
select
ceil(dbms_random.value(1,10)),
ceil(dbms_random.value(1,50))
from all_objects where rownum < 100;
insert into depts(articleid,deptid)
select
ceil(dbms_random.value(1,10)),
ceil(dbms_random.value(1,50))
from all_objects where rownum < 100;
INSERT INTO subscriber_options (
   EMAILID, audienceid, topicid,
   regionid, deptid)
select
ceil(dbms_random.value(1,10)),
ceil(dbms_random.value(1,50)),
ceil(dbms_random.value(1,50)),
ceil(dbms_random.value(1,50)),
ceil(dbms_random.value(1,50))
from all_objects where rownum < 100;
commit;If a subscriber hasn't chosen any options, then no rows will exist in the subscriber_options table, which implies that they will receive all articles.
I am struggling with this query.. can this be achieved using only 1 query or is this a case where some PL/SQL is required?
All I really want to know is if a given subscriber option matches an option for a given article, using the following boolean logic (topic OR audience) AND dept AND region.
Because I'm more concerned with row existence, I thought of using the "EXISTS" with subquery approach.
Thanks for tips and advice.

Well.. a little persistence, and I think I cracked this nut. ;-)

From there, I use this count to "short-circuit" the predicates.. if count=0 OR exists subquery with inner join on chosen options matched to article.

Create a BC with intersection table as base table.???

Hi Axel,
U have replied that for MVG with M:M create a new BC with the intersection table as the basetable.

Hi Axel,
Thank u for ur information its more useful also. Iwant to know one morething .will make u clear about the situation. I need to create an MVG taking Campaign and Offer BCs having M:M link between them. did i need to create an MVG Applet in Offer BC or in Action Employee? Intersection table comes into picture when i need to create a MVG in M:M link without using association applet.

Adding/removing many-to-many associations with intersection tables

Hello,
I am using Jdeveloper 11g with ADFBC.
I have some many to many associations in my application. For example User and Category are associated and there is an intersection entity (UserCategory - Columns are UserId, CategoryId) to save these associations.
What is the correct method for adding or removing categories assigned to user?
Thanks.
Edited by: Deniz Gulmez on 01-Nov-2009 03:25

I found an example for Jdeveloper 10g, which is discussed [ADF] Adding/deleting entries in a many-to-many relationship
In that example, many-to-many association is defined as two 1-to-many associations. Actually i've been searching since last week for an example which is made with many-to-many associations but no help. I will change my Model structure if it is not an efficient way to define many-to-many associations with intersection tables.
I wonder if it is possible to write some methods like :
addCategoryToUser(String userId, String categoryId)
removeCategoryToUser(String userId, String categoryId)
addCategories(String userId, List categoryIds)
vs.
Of course i am able to do these by creating a new Row in UserCategoryView (Intersection view), setting it's attributes and saving. Or the opposite, finding the row in intersection table and deleting it.
For example:
public void removeCategoryFromUser(String userId, String categoryId){
ViewObjectImpl vo = this.getUserCategories1();
vo.setWhereClause("USER_ID = :userId AND CATEGORY_ID = :categoryId");
vo.defineNamedWhereClauseParam("userId", null, null);
vo.defineNamedWhereClauseParam("categoryId", null, null);
vo.setNamedWhereClauseParam("userId", userId);
vo.setNamedWhereClauseParam("categoryId", categoryId);
vo.executeQuery();
Row row = vo.first();
row.remove();
I wonder if there is a more efficient way. Any samples would be appreciated.

Intersection table

Hello,
I have the table customer:
CREATE table customer
cust_id NUMBER(5),
phone_number NUMBER(10) NOT NULL,
first_name VARCHAR(12) NOT NULL,
last_name VARCHAR(30) NOT NULL,
credit NUMBER(5, 2) DEFAULT 0 NOT NULL,
CONSTRAINT cust_pk PRIMARY KEY (cust_id),
CONSTRAINT phone_unique UNIQUE (phone_number)
and the table movie:
CREATE TABLE movie
title VARCHAR(30) PRIMARY KEY,
production_year NUMBER(4),
rating VARCHAR(5) NOT NULL,
max_days NUMBER(1) DEFAULT 1,
quantity NUMBER(2),
CONSTRAINT check_ratings CHECK (rating IN ('G', 'PG', 'PG-13', 'R', 'NC-17')),
CONSTRAINT check_maxDays CHECK (max_days IN (1, 3, 7))
now I want to store the rent of a movie, I come up with the following table:
CREATE TABLE cust_rent_movie
title VARCHAR(30),
cust_id NUMBER(5),
rent_date DATE DEFAULT current_date NOT NULL,
return_date DATE,
CONSTRAINT cust_rent_movie_pk PRIMARY KEY (title, cust_id, rent_date)
Is the table cust_rent_movie an intersection table. Have I to declare the title and cust_id are foreign keys, the primary key consist of an extra attribute the rent_date.
When a customer rent a movie I want to subtract one from the movie.quantity and when the customer return the movie I want to add one to the movie.quantity subtract from customer.credit

Is the table cust_rent_movie an intersection table. Yes. It allows for a many to many relationship between customer and movie, though it would seem that you would want to connect customers to a table with 1 row per physical DVD. That table could then be joined to the title movie table in order to get the title.
Have I to declare the title and cust_id are foreign keys, the primary key consist of an extra attribute the rent_date.Title is not a good column to use for the primary key, consider adding title_id. Though unlikely, it is possible that the title wil be updated, ie to correct a typo. Currently you will not be able to update it as there mat be dependent transactions. You will want to add a PK for this table, ie cust_movie_pk.
When a customer rent a movie I want to subtract one from the movie.quantity and when the customer return the movie I want to add one to the movie.quantity subtract from customer.creditIt is usually better to derive values like quantity at run time (or query time) rather than trying to keep a running total of all changes. With appropriate indexes you should be able to quickly calculate that column when required.
CONSTRAINT phone_unique UNIQUE (phone_number)This will cause a problem for you if you have multiple customers in the same household with the same phone number.

How to dynamically display the data from a table base on row selection of another table in ADF

Hi ,
I have a requirement in ADF. I need to change the data of a table based on row selection of another Table . Both the table have a Parent Child relationship between them. They have a common attribute say department_id.
                                                                                     For this I created bind variable in view object of employees table and wrote a where clause in the sql query using that bind variable. Then I created method for selection listener of department Table in java bean.
My method is following
    public void onrowselection(SelectionEvent selectionEvent) {
        RichTable richTable = (RichTable)selectionEvent.getSource();
                        CollectionModel tableModel = (CollectionModel)richTable.getValue();
                        JUCtrlHierBinding adfTableBinding = (JUCtrlHierBinding)tableModel.getWrappedData();
                        Object selectedRowData = richTable.getSelectedRowData();
                        JUCtrlHierNodeBinding nodeBinding = (JUCtrlHierNodeBinding)selectedRowData;
                oracle.jbo.domain.Number newVal = (oracle.jbo.domain.Number) nodeBinding.getAttribute("DepartmentId");
                Number pallet = newVal.bigDecimalValue();
                System.out.println("Selected values " + pallet);
        BindingContext bindingctx = BindingContext.getCurrent();
                      BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
                      DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
              DCIteratorBinding dciter = bindingsImpl.findIteratorBinding("EmployeesView1Iterator");//access the iterator by its ID value in the PageDef file
                      ViewObject vo =dciter.getViewObject();
                      vo.setNamedWhereClauseParam("DepartmentId", pallet);//enter your value
                      vo.executeQuery();
It is printing the selected value of department id from department table in the log. But it is not able to pass the value to employees view. It is showing the following error in the log
"Definition DepartmentId of type Variable is not found in EmployeesView1."
I will be very thankful if someone helps me to solve this errror or is there any other way to achieve the same requirement.
Thanks

Note quite sure why you simply wont create a viewlink for the viewobject the tables are based on..
The viewlink attribute will be based on the departmentId and it's a simple master detail relationship which automatically uses ppr.
However, if both tables are on the same page; using your hack about;
On the underlying viewobject, define a viewcriteria e.g. "listById" and set your bind variable here.
I would bind table two to a RichTable component:
RichTable t2;
public void onrowselection(SelectionEvent selectionEvent) {
        RichTable richTable = (RichTable)selectionEvent.getSource();
                        CollectionModel tableModel = (CollectionModel)richTable.getValue();
                        JUCtrlHierBinding adfTableBinding = (JUCtrlHierBinding)tableModel.getWrappedData();
                        Object selectedRowData = richTable.getSelectedRowData();
                        JUCtrlHierNodeBinding nodeBinding = (JUCtrlHierNodeBinding)selectedRowData;
                oracle.jbo.domain.Number newVal = (oracle.jbo.domain.Number) nodeBinding.getAttribute("DepartmentId");
                Number pallet = newVal.bigDecimalValue();
                System.out.println("Selected values " + pallet);
               refreshTable2(pallet);
        BindingContext bindingctx = BindingContext.getCurrent();
                      BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
                      DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
              DCIteratorBinding dciter = bindingsImpl.findIteratorBinding("EmployeesView1Iterator");//access the iterator by its ID value in the PageDef file
                      ViewObject vo =dciter.getViewObject();
                      vo.setNamedWhereClauseParam("DepartmentId", pallet);//enter your value
                      vo.executeQuery();
private void refreshTable2(Number pallet){
RichTable x=getT2();
CollectionModel cm=(CollectionModel)x.getValue();
JUCtrlHierBinding jcb=(JUCtrlHierBinding)cm.getWrappedData();
BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
DCIteratorBinding dciter = bindingsImpl.findIteratorBinding(jcb.getName()+"Iterator");
ViewObject vo =dciter.getViewObject();
ViewCriteriaManager vcm=vo.getViewCriteriaManager();
ViewCriteria vc=vcm.getViewCriteria("listById");
vo.applyViewCriteria(vc);
vo.setNamedWhereClauseParam("DepartmentId",pallet);
vo.executeQuery();
AdfFacesContext.getCurrentInstance().addPartialTarget(getT2());

How to select rows in adf faces table

Hi guys
im new to adf faces .I created a adf faces table with some data.My task is to select one row and if i click tht row, the data of tht row will be displayed in an input text fileds.How can i select a row in a adf faces table and give actions to rows...i read so many tutorials...none of them didnt give a correct idea....plz help me...
thanks in advance..

You're here in the Sun JSF forum, not in the Oracle JSF forum.
Try here: JDeveloper and ADF
If the ADF datatable is technically comparable with the RI datatable, check http://balusc.xs4all.nl/srv/dev-jep-dat.html to get some insights how to retrieve the selected row object.

JDEV 10.1.3: Using "Create" binding on BC view object with ADF Faces Table

Hello,
I am trying to get this to work, but to no avail:
I've got a very simple page (ADF Faces - JSPX) created by dragging an iterator from the data control pallete on to my page and picking "ADF Table..." as my chose to create. This creates a table on my page that allows me to edit each row in place. Very nice.
Now, I dragged the create operation for that iterator on to the page. What I had hoped to see is that when I click "Create," a new blank row appears in my table (well, at least a row that is blank except for any default values specified in the EO/VO and my overriden create() method).
However, this doesn't happen. The page submits and refreshes, but no blank row shows up. I initially tried setting the Create button to do partial submit and setting the partialtriggers for the table to include the Create button, to no avail. I also tried it without the partial submit with the same results.
So:
1). Should this work, or is this behavior a bug.?
2). If not, is there a different/better way of doing it?
Regards,
John

G'day John
I think I can give you a hint of what is occuring... I'm still trying to work out what is happening exactly.
In JDev 10.1.2 UIX, when the user invoked the create action, they would see the blank record added to the underlying table. Under 10.1.3 Faces the functionality is somewhat different.
When you the user clicks on the create action a blank record is created but not shown in the table control. To prove the blank record is there try this:
1) Build an ADF Input Form based on the same VO iterator
2) In your JSF navigation, create a navigation case between the existing page and the new page, and another back again,
3) In the existing page, map the Create button's action attribute to navigate to the ADF Input Form
4) In the ADF Input Form, map the Submit button's action attribute to navigate to the ADF Table page.
Now when you run your app, notice when you create a new record in the ADF Table which automatically takes you to the ADF Input Form, note the blank record, and the details you enter into the record here and submit, are then visible in the ADF Table on the return.
This is a long way of proving that the new record is in the table. It's just you can't see it.
I have a theory which I'm trawling through the newly updated documentation to verify. This issues goes back to the VO createRow vs insertRow method calls that have been documented by Steve Muench a couple of times. I'm guessing the table control is now smarter and doesn't show createRow records, only insertRow records.
Read one of Steve's posts here regards the createRow vs insertRow method calls:
http://www.oracle.com/technology/products/jdev/tips/muench/blankrow/index.html
If I find anymore info I'll endeavour to post it.
Meanwhile this of course doesn't help you if you actually want to show the blank row in the ADF Table editable control, but I'd thought I'd give you an idea of what's happening behind the scenes.
Hope this helps.

ADF Editable Table : CANNOT Insert Multi Rows , Please hellppppssss

Hi All,
Our customer requirement is being able to insert Multi Rows in an Editable Table and submit ALL of them with just one Click ?
Is it Really Possible ?
I have tried, even I can insert three Empty Rows and Fill them all with values, when I press Submit ONLY one row will be submitted, the other TWO will become BLANK again, is this my code is wrong ?
Or this is limitation of ADF Editable Table ?
Here is my codes, I have tried two ways, all same problem :
(1) public String create_action() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("Create");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
public String myCreate_action() {
create_action();
create_action();
create_action();
return null;
(2) public String createMultiRows() {
DCBindingContainer dcbc = (DCBindingContainer)getBindings();
//get iterator binding
DCIteratorBinding ib = (DCIteratorBinding)dcbc.get("DeptView1Iterator");
// get viewobject
ViewObject vo = ib.getViewObject();
System.out.println(vo.getCurrentRowIndex());
vo.clearCache();
int currentRowIndex = vo.getRowCount() -1;
Row row1 = vo.createRow();
row1.setNewRowState(Row.STATUS_NEW);
vo.insertRowAtRangeIndex(++currentRowIndex, row1);
Row row2 = vo.createRow();
row2.setNewRowState(Row.STATUS_NEW);
vo.insertRow(row2);
Row row3 = vo.createRow();
row3.setNewRowState(Row.STATUS_NEW);
vo.insertRow(row3);
return null;
Please help... I am stuck ...
Thank you very much,
xtanto

Xtanto,
Could you try changing
bindings.getOperationBinding("Create");to
bindings.getOperationBinding("CreateInsert");in your first example to see if it fixes your problem?
Regards,
John

How to create multiple rows in a child table from the multi select Lov

Hi
We have Departments and EmployDept and Persons tables and each employee can associate multiple departments and vice versa.While creating a Department page there should be a Multi Select LOV(values from Persons table) with search option for the Persons.From the search panel we can select multiple persons for that department.Suppose we have selected 5 persons and click on submit, then it should create 5 rows in the EmployDept table for 5 persons with that department id.
Any inputs on how to implement this scenario please..

Maybe you can get some ideas from here -
