SetWhereClause of ViewObject
Hi,
I am setting ViewObject's where clause by using setWhereClause(strWhereClause).
strWhereClause is of sort ATTRIBUTE_ID IN (42912850, 42302602, 43326003, 43582985, 43582465, 43474749......)
But number of elements in IN clause are greater than 1000 and I don't want to use OR.
So I am thinking to use it as ATTRIBUTE_ID IN (SELECT * FROM TABLE(CAST(m_AttributeIDList AS NUMBERLIST))) where NUMBERLIST is defined as
CREATE TYPE NumberList AS TABLE OF NUMBER;
Can anyone please help me on this, what code should be written in java front end side and what functions or procedure should be written in oracle to achieve this and how should I call it from java.
Thanks.

Hi to all,
I'm new with oaf and in mi AM i have to VO that I use to find relative information to the one is shown to the user on a query region, after the user pressed the go buton the CO request the AM tho load both VO and those information are used to show in a popup region to display and update. the main problem is when the popup region closes it send a submit to the server an the error "View object may not have been properly initialized during Update." is displayed
The main page and the popup uses the same AM, the initM2mVo() and initTavleVo() are called by the CO at the processRequest of the main PG, the popup dosen´t have a CO.
This the AM that uses the main PG and the popup region

thanks to all.I thing I got the problem.
I have the following configuration:
One Main Page and external RN that is call as popup in main page
2 VO, queries by java code, one to capture some information that is used to query the 2 VO that I use to update information by the popup.
One AM that is map only in the Main Page. (Initially I had the external RN mapped to same AM as the main PG, but I remove it).
The solution was remove the mapping of the AM from the external region and in the messageimput of the external region set the View instance and view Attribute manually in this fields (http://screencast.com/t/uDTALEedCh do not use the wizard ) as the one instanced am the AM, so the problem it seem that was that defining an AM to the external region create a new instance, causing that it can not see the information that I load manually in the VO by query it them.
for this case there is not need to use the next code, because the Rows are load with information by the query in the java code, this only will have to be made when inserting a new row .
public void initM2mVo(){
//get a handle to the View Object that we wish to initialize
OAViewObject vo = (OAViewObject)this.getTascTransEqInstM2mVO1();
if (!vo.isPreparedForExecution()) {
vo.setMaxFetchSize(0);
vo.executeQuery();
//Create a blank Row
Row row = vo.createRow();
//Attach that blank row to the VO. Data will be fed into this row, when the user types into the fields
vo.insertRow(row);
//Set the status of the blank row to initialized. This tells OA Framework that record is blank and must not be included in DML
//Operations until changes are made to its underlying VO [via screen fields]
row.setNewRowState(Row.STATUS_INITIALIZED); -
ViewObject.setWhereClause() strangeness.
I've had an interesting problem when using ViewObjects:
A JSP page uses a ViewObject, and sets the where clause as follows:
view.setWhereClause("Vendorid = :0");
view.setWhereClauseParam(0,anId);
view.executeQuery();
The query executes just fine. A subsequent JSP page uses the same ViewObject, and sets the where clause as follows:
view.setWhereClause("Id = :0");
view.setWhereClauseParam(0,anId);
view.executeQuery();
The problem occurs on the second use of the ViewObject: the row is not found! Upon investigation (Using Diagnostic.properties) I discovered that remenants of the where clause from the first use of the ViewObject remain. The query that actually gets executed is as follows:
[169] jbo.server(int) SELECT Ricscontent.ID, Ricscontent.PARENTID, Ricscontent.VENDORID, ...cut... FROM RICSCONTENT Ricscontent WHERE (Id = :0) AND Ricscontent.VENDORID = :1
As you can see, the where clause includes the Vendorid. When executing the second query first, it works just fine.
Am I doing something wrong, or is this a defect? Is there a work-around to this problem? Any help would be greatly appreciated.
Thanks,
David

BC4J, ViewObject: setWhereClause vs ViewCriteria
1.What is the difference between using setWhereClause and ViewCriteria object?
2.When is better to use the first one and when the second?
3.When used both, which one has priority, or are they anded together?
Could anybody answer these questions?
Thanks, TomManuel,
There is also another method, getEstimatedRowCount(), which is the most efficient. It will perform a
SELECT COUNT(*) FROM (your query with conditions)
which puts all the work in the database and just returns the count.
getFetchedRowCount() just tells you how many have been fetched so far and getRowCount() actually fetches all the rows into view/entity cache and then returns the total. -
Where clause with Bind Variable in ViewObject
As per recomendations from Jdev team they say that using Bind varialbles in where clause will improve the performance (Option 1) But it is causing us to create more view objects.
Example : Lets say we have a View Object EmpVO
Option 1:
ViewObject vo=context.getViewObject("EmpVO");
vo.setWhereClause("EMPNO=?");
vo.setWhereClauseParam(0,st);
(or)
Option 2:
vo.setWhereClause("EMPNO="+st);
If we want to use same View Object "EmpVO" in another Action Class
ViewObject vo1=context.getViewObject("EmpVO");
vo1.setWhereClause("DEPTNO=?");
vo1.setWhereClauseParam(0,str);
It this case it throws an error saying BIND VARIABLE already exits. So we have to make another View Object.
Where as if we did not use bind variable but used Option 2 approach the same view object can be used in multiple pages.(at the expense of performance as per Jdev team)
Are we doing something wrong here or are there other ways to use the same view object when using bind variable in where clause.
ThanksI haven't been using BC4J for a while, but I seem to recall that the recommendations are that you don't set the where clause at runtime: You're supposed to define your view with the bind parameter already in it.
So you'd probably define an EmpsForEmpNoVO and type "EMPNO = ?" in the where box. (There are other ways of finding a single row/entity and one of those may well be more efficient. Perhaps a better example of where you might want a view of employees is WHERE DEPTNO = ?.)
IIRC, all instances of a particular type of view share the same definition, so you have to be careful if you alter that at runtime. However, I think everything's set up so that you can have many different (and separate) resultsets for a single view (instance) - meaning that it's possible to "run" a view for (e.g.) two different ids. (It's definitely possible to create two different instances of a view from its definition - and the resultsets will definitely be separate then. I think there's a "create" method on the application module; I remember that "find..." always returns the same instance of the view.)
Hope that's a push in the right direction (since no-one else had replied - and I hope not too much has changed since 9.0.3)....

Object use count is negative when two users access ViewObject at same time
I need help!
In my application, if two users execute the same view object at the same time, the users will see a combination of the two record sets: One user will receive their requested result set plus part of the other user's set and the other will receieve only a partial result set.

SQL only ViewObject with WhereClause
I have a sql only viewobject. My query that makes this viewobject contains a where clause to indicate a join. The viewobject works fine but I cannot do the setWhereClause(string) to add on criteria if I want to search the view. It looks like bc4j doesn't know there already is a where clause started in the query and so it tacks on a new WHERE clause which makes a bad query.
Any suggestions on how to get around this?Darko, we try hard to offer much more functionality (and advanced functionality) than a simple JDBC prepared statement.
I tried creating an expert mode SQL query:
SELECT DISTINCT EMPNO, ENAME FROM EMP.
Then at runtime I do:
vo.setWhereClause("ENAME LIKE '%'||?||'%');
vo.setWhereClauseParam(0,'A');.
and this works fine. The trick is that since expert-mode view objects get wrapped as inline views (to allow runtime appending of WHERE clause, actually), you need to select any column in the select statement to which you want to later refer in a dynamically-appended where clause.
If you want to prevent the inline-view wrapping, you can write the following code in your view object's ViewObjectImpl subclass to force the VO to NOT be treated as an expert-mode SQL VO.
// Goes in your view object impl subclass
public void create() {
// Force this VO to NOT be treated as an expert-mode SQL, so that
// its query does not get wrapped as an inline view.
getViewDef().setFullSql(false);
}I used this trick above to create an expert mode query like:
SELECT DISTINCT deptno FROM empand then at runtime I add a dynamic where clause that refers to a column
in EMP that is not in the select list like this:
ViewObject vo = am.findViewObject("View1");
vo.setWhereClause("ename like '%A%'");
vo.executeQuery();
System.out.println(vo.first().getAttribute(0));and this causes the query to come out as:
SELECT DISTINCT deptno FROM emp WHERE ename like '%A%'.
instead of:
SELECT * FROM (SELECT DISTINCT deptno FROM emp) QRSLT WHERE ename like '%A%'which would cause an error due to the fact that ename is not in the select list of the original (wrapped, inline) query. -
I am using JDev 9.03.
I created a VO and in expert mode I added a where clause that accepts 1 parameter. I have a uiXML page that needs to pass a parameter to a second page and use that parameter in the VO where clause. I need to have the parameter set in the where clause before the page can be rendered. How do I do this?I have been watching another thread and received an answer as to how to do this within a servlet.

You must get exactly the same object that bc4j has created.
From bajacontext you can reach everything...
like appmodule.. and even ViewObject..
Add a null event, which runs before your page is rendered...
<event name="null">
<bc4j:findRootAppModule name="PenCmpAppModule">
<bc4j:findViewObject name="RdmsViewUsage">
<method class="FrmFilters" method="handleRdms"/>
</bc4j:findViewObject>
</bc4j:findRootAppModule>
</event>and create an event handler...
public static EventResult handleRdos(BajaContext context, Page page, PageEvent event)
{ ViewObject vobj= ServletBindingUtils.getViewObject(context);
HttpSession session = context.getServletRequest().getSession(false);
String OrgId=(String)session.getAttribute("S_ORGID");
vobj.setWhereClause("ORG_ID='"+OrgId+"'");
vobj.executeQuery();

Modfiying SQL in a viewObject in a differenat frame
I wish to collect information from one frame and display the results of a query in another frame.
My initial idea was to generate an event when the submit bottom was pressed, modify the SQL in the viewObject in the eventHandler class and then have that viewObject displayed in the results frame.
Do I put the event in the .uix for the entire page or just in the .uix for the individual frame.
How do I get the viewObject? Right now it is scoped in the results frame.
How do I modify the SQL query by appending a where clause?
I can not find an example in the docs. If there is, please tell me where.
Regards,
BillThis falls in the the realm of answering my own question, but if the JDeveloper team could say right track / wrong track, I would appreciate it.

How do I get the viewObject? Right now it is scoped in the results frame.Get the ViewObjecy from the ApplicationModule
From BC4J API
findViewObject
public ViewObject findViewObject(java.lang.String voName)
Finds the named View Object. The View Object name passed in (voName) may or may not be qualified with the name of the containing Application Module. If it is, the View Object name is said to be an AM-qualified View Object name. If not, the name is said to be an unqualified View Object name.
How do I modify the SQL query by appending a where clause?Use the method setWhereClause in the ViewObject class
From BC4J API
setWhereClause
public void setWhereClause(java.lang.String cond)
Sets a WHERE clause bind value of the View Object's query statement.
I can not find an example in the docs. If there is, please tell me where.I could not find an example in the docs for getting a ViewObject from the ApplicationModule, but I found one for
Creating and Changing View Object Queries in Code
Once again this is what I found and have not tested it yet. I believe it will work, but comments from the JDeveloper team would be appreciated.

URGENT: executeQuery after setWhereClause causes infinite loop
Hi,
- I'm using jdev 9.0.3.2.
- I have a JTable bound to a ViewObject.
- I set the vo's whereClause, the where clause has some syntax error.
- I call executeQuery
- The JBO exception is shown.
- I press ok.
BUT:
- The JBO exception is called again and again, the reason is getEstimatedRowCount called again and again by the repaint event.
I noticed the following code in JUIteratorBinding :
public void executeQuery()
synchronized(getSyncLock())
if (mIsAlive && mIsBound)
try
getRowSetIterator().getRowSet().executeQuery();
catch(Exception ex)
reportException(false /*markDead*/, ex);
reportException(false -> means do not markDead
is this OK?
Please help.
Thanks OgnianYou're hitting a reported bug 3090348
A known workaround is to reset the erring clause after execute and exception like:
private void setWhereClause_actionPerformed(ActionEvent e)
//here it starts
JUIteratorBinding ib=panelBinding.findIterBinding("EmpView1Iter");
try {
ib.getApplication().setErrorHandlerActive(false);
ib.getViewObject().setMaxFetchSize(100);
ib.getViewObject().setWhereClause("empno = xxx"); //the where clause
is intentional wrong!!
ib.executeQuery(); //one JBO exception is OK, but not an endless loop
until a stack overflow happens!
catch (JboException je)
ib.getViewObject().setWhereClause(null);
ib.getApplication().setErrorHandlerActive(true);
panelBinding.reportException(je);
ib.executeQuery();
//set a breakpoint here and go inside execute query
- this reports the exception once... -
ADF BC + ADF Faces: How can consult a ViewObject in a backing bean.
Hello comunity i'm new in ADF tecnology, need to consult a VO in a backing bean code, but these are not instances in page definition.
Thanks Comunity.Hi Peter you can consult your aplication module and all VO including inside using these code:
String amDef = "model.AppModuleImpl";
String config = "AppModuleLocal";
String retorno = "";
ApplicationModule am = Configuration.createRootApplicationModule(amDef,config);
ViewObject myVO = am.findViewObject("YourVO");
Then you can filter your VO if you need
myVO.setWhereClause("id = : 0");
myVO.setWhereClauseParam(0, var);
myVO.executeQuery();
And iterate by the results
while (myVO.hasNext()) {
myVO.next();
Row myRow = myVO.getCurrentRow();
Number id= (Number)myRow .getAttribute("Id");
Good Luck -
Hello,
I'm facing strange behaviours in ADF viewobject. I have a viewobject PropertyView1. I need to list the properties only for a particular user. And also within that , I need to display based on the property status.
So I have a dataaction (DA1) which binds to a app module function ,
ViewObject vo = getPropertyView1();
vo.setWhereClause(" Property.USERID = :1 ");
vo.setWhereClauseParam(0,new Long(uid));
vo.executeQuery();
This sets the view object to display only the properties of a particular user. This DA1 forwards to a datapage (DP1) on "Success", The DP1 contains the ADF Read-Only table for the propertyview1 view instance.
I have another function which should display only the "new" properties for a particular user.
Another data action (DA2) which contains the function,
ViewObject vo = getPropertyView1();
vo.setWhereClause(" Property.PROPSTATUS = :1 and Property.LAGENT = :2 ");
vo.setWhereClauseParam(0,status1);
vo.setWhereClauseParam(1,new Integer(uid));
vo.executeQuery();
This displays the user properties which are "New". Similar to the first data action, DA2 -> DP2 on success.
The following Sequence of actions gives strange behaviours every time,
1. Execute the first dataaction (DA1) . It works properly , Provides me with correct list of properties.
2. Execute Second dataaction (DA2). There are no rows which match the criteria. So I get "No Records Found" in Dp2.
3. execute first data action again, It provides me No records found as well as Errors.
The errors are,
" Bind variable does'nt exist"
Somehow there are two bind parameters set for DA1, while there is only one bind parameter in my where clause. And this happens only on the second time. I'm able to ececute DA1 correctly on the first time.
Also, Pelase let me know if I Have two create two view instances for these types of queries. Or Is there a way to revert back to all the rows originally in the propertyview1 view object (The view object has no where clauses in the definition), after executing the DA2 or DA1 dataction. I hope i was clear in the above questions.
Thanks a lot.Just a guess: call vo.setWhereClauseParams(null) before setting new parameters.
From the VO API Doc:
Note that calling setWhereClause() does not clear the previous settings of WHERE clause parameters. To reset WHERE clause parameters in the middle tier, call ViewObjectImpl.setWhereClauseParams(Object[]) explicitly with a null value. For example:
vo.setWhereClauseParams(null); -
Where to call a ViewObject's setWhereClauseParam() ?
Simple question:
Where to set a where clause param for a ViewObject defined at design time?
I have the VO as Read-only form on a DataPage, and I want
to show a different row based on a HttpRequest parameter send to the DataPage. For example, show the employee with id=?, having EmployeeVO and HttpRequest parameter 'id'.Check out this how-to for a sample of how to do it.

Dynamically set ViewObject where clause dynamically from Java bean
I have a requirement to display all of the records from a table when the JSP is first brought up, so my View Object looks like this:
"select emp_name from emp"
Then the users wants to ability to pass paramters to that View Object to refine the list so from by Java class I tried to do this:
ViewObject vo = cpd.findViewObject("EmpViewObject");
vo.setWhereClause("empName = :1");
vo.setWhereClauseParam(1,varEmpName);
vo.executeQuery();
But I am getting JBO errors and I'm not sure what I'm doing wrong. Can anyone offer a hint as to how I can do this?this is exactly how the code is done -
1. emp_name in the View Object
2. emp_name in the where clause
The two are identical. I have tried many variations of this - any time I set the where clause from my bean I get an error.
When I take the SQL stmnt and run it in TOAD it returns expected rows when I run it in the SQL worksheet in JDev it gives an invalid Identifier - but if I hard code the where clause in the View Object it returns the same results as TOAD.
