Create dynamic view link

my problem is
I build the first view link by using createViewObjectFromQueryStmt method on my application module instance ,then I build the second view link by using createViewObjectFromQueryStmt method on my application module instance,now when I use myAppModule.createViewLink(),he give me an exception about the definition of the viewLink.
please can you explain the first parameter of the method createViewLink() and how I can get it.
thanks in advance

In that case, the first parameter is the name of the ViewLink which you can freely assign. Later you can retrieve the VL from the AM by calling findViewLink( name ).
But if you create your VOs dynamically from a statement, then you probably need to use createViewLinkBetweenViewObjects() since you don't have a prepared VL definition. Haven't done it myself yet, but it should work.

Create dynamically View Link

hi
please can you explain the first parameter from the method (createviewlink(string,VO,VO)),because i want to build view link between two dynamic VO's
it better as an example
thanks in advance

If that's DBTransaction.createViewLink() then the first parameter is the full def name of the ViewLink.
For example "some.rather.long.package.path.Dept2EmpViewLink".
So you define the ViewLink using the wizard in JDev at design time, but instantiate it according to that definition at runtime.

How to create dynamic View Object and Dynamic Table

Dear ll
I want to create a dynamic view object and display the output in a dynamic table on the page.
I am using Jdeveloper 12c "Studio Edition Version 12.1.2.0.0"
This what I did:
1- I created a read only view object with this query "Select sysdate from dual"
2- I added this View object to the application module
3- I created a new method that change the query of this View object at runtime
 public void changeVoQuery(String dbViewName) {
 String sqlstm = "Select * From " + dbViewName;
 ViewObject dynamicVo = this.findViewObject("DynamicVo");
 if (dynamicVo != null) {
 dynamicVo.remove();
 dynamicVo = this.createViewObjectFromQueryStmt("DynamicVo", sqlstm);
 dynamicVo.executeQuery();
4- I run the application module for testing the method and I passed "Scott.Emp" as a parameter and the result was Success
5- Now I want to show the result of the view on the page, so I draged and dropped the method from the data control as a parameter form
6- I dragged and dropped the view Object "DynamicVo" as a table and I choose "generate Column Dynamically at runtime". This is the page source

Have you seen Shay's video https://blogs.oracle.com/shay/entry/adf_faces_dynamic_tags_-_for_a
All you have to do is to use the dynamic table to get your result.

Error in creating dynamic view

Hi,
I am using the following to create a dynamic view which will be created on runtime and conditions will be provided by user. Here is the code:
CREATE OR REPLACE PROCEDURE DYN_VIEW_PROC(PARA IN NUMBER)
AS
DEPT_NO NUMBER(3) := PARA;
DYN_QUERY VARCHAR2(1000);
BEGIN
DYN_QUERY := ' CREATE OR REPLACE VIEW DYN_VIEW
AS SELECT EMPNO,ENAME,DEPTNO FROM EMP_NEW
WHERE DEPTNO > :1 ';
EXECUTE IMMEDIATE DYN_QUERY USING DEPT_NO;
END;
But when i execute this code i got the following error:
SQL> EXEC DYN_VIEW_PROC(10);
BEGIN DYN_VIEW_PROC(10); END;
ERROR at line 1:
ORA-01027: bind variables not allowed for data definition operations
ORA-06512: at "SYS.DYN_VIEW_PROC", line 9
ORA-06512: at line 1
If i hardcode the condition in the defenation of view then it works fine. Any solution of it.

It looks strange.And more so, since the view name seems the same across each invocation (unless the example is missing that detail). So, if two users were creating this view one after the other and then subsequently try to use it, what would each user see in their output???
Not the rows based on their where condition, possbily.
You would create the view only once with all the necessary joins and any static conditions. Then users would use it as and when necessary, supplying their custom where condition on top of it.
What is the need you are trying to solve using this dynamic view creation?

Question. Do you know what SQL is? Do you what the purpose of SQL is? Do you realise that SQLs are programs that
contains instructions on how to process/manipulate/fetch data? And that like all programs, support variables? And
that is is truly silly to create a thousand and one copies of the very same program to fetch a data where the only
difference in the program is the values?

Thanks
jagadeesh

Maybe you can use only one view ... being called several times (different instances). And it dynamically creating components at runtime.

How to create a view link between ViewObject Instance in nested AM

Hi all,
I am using JDev 11.1.1.0. I am a bit confused about working with nested AM
I have found the sample #33 in http://blogs.oracle.com/smuenchadf/examples/ to solve my problem, where the link is created programmatically.
Is it that an old example? Because it seems to be that I can create the link in a declarative way in a tab of the Application Module.
What is the advantage of creating the link on runtime?
Thanks

This sample is really old.
If you can do the link declarative just do so. I guess this was not possible in the older version of jdev.

oracle.jbo.NoDefException: JBO-25058: Definition Level3View of type Attribute not found in Level2View_Level2Level1FKLink1_Level2ViewThe thing is, Level3View isn't in the Level2Level1FKLink viewlink.
I've been reading about something similar here
BC4J Master-Detail-Detail
but I am still unsure of what the problem is.
Thanks in advance.

I found the answer here:

Create view link programatically

Hi all,
I am working on this weird requirement.
Basically, I have to create a detail table on a search resullt table. The search result is seeded search, for Item Advance search in Oracle PIM module which is not based upon a VO. The search result table is dynamically built at run time in the EgoItemSearchHelper class and that's where they build the search result VO (EgoItemSearchResultsVO).
Now, I need to access this VO in the controller class, and create a view link programatically between details table VO and this VO. The problem is since I do not have Impl class for the EgoItemSearchResultsVO, how do I accees the column that is the key attribute. Second I do not know how to create view link between the two VOs programatically.
Please help it's urgent.
Thanks

Pratap, My problem is the seeded VO is in seeded AM and my details VO will be in my custom AM, I don't know if we can have a view link between View objects that are in different AMs.
To bypass that problem, I tried to create a VO in the seeded AM programatically and then created a view link. Now since the AM is seeded, and I am adding my details VO to this AM programatically, I thought of creating a table also programatically on the detais VO.
In the end it does not work, I end up getting a show button on the main table, but when I click I get an error (Cannot find <null> attribute in the EOGITEMSEARCHRESULTVO) which is the seeded VO class. Unfortunately there is no boolean variable on the dynamic seeded VO, so don't know what to put in oatablebean.setDetailViewAttributeName("") method;
Any clues on this, appreciate all responses from the forum gurus.
ViewObject voEmp = oaapplicationmodule.createViewObject("MyEmp", "xxuss.oracle.apps.ego.item.eu.server.DetailsOrderLinesVO");
ViewObject voEmp = am.createViewObject("MyEmp", "xxuss.oracle.apps.ego.item.eu.server.DetailsOrderLinesVO");
AttributeDef[] prjLinkAttrs = new AttributeDef[]{oaapplicationmodule.findViewObject("EgoItemSearchResultsVO").findAttributeDef("INVENTORY_ITEM_ID_B")};
System.out.println("definition for attr = "+ prjLinkAttrs[0]);
AttributeDef[] taskLinkAttrs = new AttributeDef[]{voEmp.findAttributeDef("InvId") };
ViewLink vl = am.createViewLinkBetweenViewObjects("MyLink3",
"DetailInv", // accessor name--more on this below
am.findViewObject("EgoItemSearchResultsVO"), // master
prjLinkAttrs, // department attributes
voEmp, // detail
taskLinkAttrs, // employee attributes
null); // assoc clause
System.out.println("view link =" + vl.getName());
OATableBean tb = (OATableBean)createWebBean(oapagecontext,TABLE_BEAN,null,"table");
tb.setViewUsageName("MyEmp");
OAMessageStyledTextBean beans = (OAMessageStyledTextBean)createWebBean(oapagecontext,MESSAGE_STYLED_TEXT_BEAN,OAWebBeanConstants.VARCHAR2_DATATYPE,"number");
beans.setPrompt("column1");
beans.setViewUsageName("MyEmp");
beans.setViewAttributeName("InvId");
tb.addIndexedChild(beans);
oatablebean.setDetail((OAWebBean)tb);
oatablebean.setDetailViewAttributeName("SelectFlag"); // I just tried this, SelectFlag is not a boolean attribute though, is there a way to create a boolean attribute programatically for seeded VO EGOITEMSEARCHRESULTVO and set it here, will it help
oatablebean.setAllDetailsEnabled(true);

I created a static view object called StaticDepartments with the data from the DEPT table, but typed in statically.
I created a normal, entity-based EmpView VO over an Emp EO.
I created a 1-to-* view link between StaticDepartments and EmpView based on the Deptno attribute.
I added the master/detail to the AM's data model and tested, and it worked ok.
What's different about the way you're creating the view link here?
