How to get 'student_ty' instead of the' TESTDB2. STUDENT_TY(1002,Joshua,David) ".
I would like to know belongs it to which table the particular line. Yes... It's the idea of value(). but I need only the name of the table or the type name. How can I do?
If you want to select type name, right? Then use:
select anydata.GetTypeName(anydata.convertobject(VALUE(p))) typename FROM person_v p
/
TYPENAME

How to get the value of the outputtext in javascript and send it to backing bean
Hi Experts ADF,
JDev Version 11.1.1.7.0
I have the following: the value of the outputtext must be treated in javascript and the serverlistener method has the same value. I founded this value returns a string that wshould see the mouseover NIJ.
Help, please. Thanks in advance.
< af:column sortProperty = "#{bindings." OrderProposalReadClient.hints.exceptions.name}.
filterable = "true" sortable = "true".
headerText = "#{suiviewBundle.EXCEPTIONS} '"
ID = "c16" >
< af:outputText value = "#{row.exceptions}" id = "ot32" clientComponent = "true" > "
< af:clientListener type = "mouseOver".
method = "customJsFunction" / >
< af:serverListener type = "mycustomserverEvent".
Method="#{pageFlowScope.ChangeOrderProposalBean.handleServerEvent}"/ >
< / af:outputText >
< / af:column >
JavaScript
< af:resource type = "javascript" >
var customJsFunction = function (event)
{
var exceptiondata = AdfPage.PAGE.findComponentByAbsoluteId ('ot32');
AdfCustomEvent.queue ();
Returns true;
}
< / af:resource >
BackingBean
public String handleServerEvent(EC ClientEvent)
{
Please let me know how to get the value that javascript code sends here.
Let's say javascript sends the value of outputtext as "001".
So, I have to check "001" in my list and return a value that appears on mouseover.
}
Kind regards
RoyHello, Roy.
To use the value on another component of the user interface, I shows an example:
-code of the page
shortDesc = "shortDesc" >
method = "customJsFunction" / >
-the javascript code
var customJsFunction = function (event)
{
var exceptiondata = event.getSource ().findComponent("ot32").getValue ();
AdfCustomEvent.queue (event.getSource (),
"mycustomserverEvent,"
{param1:exceptiondata},
(true);
Returns true;
}
-OutputTextCase11.java
public void handleServerEvent (EC ClientEvent)
{
String param = (String) ce.getParameters () .get ("param1");
RichOutputText outputText = (RichOutputText) ce.getComponent () .findComponent ("ot1");
outputText.setShortDesc (param);
outputText.setValue (param);
AdfFacesContext.getCurrentInstance () .addPartialTarget (outputText);
}
I hope this helps you.

I'm not sure that understand what you're up to.
For as far as I understand you want to get the value of display rather than the index
I use this codepublic void StatusChangedListener(ValueChangeEvent valueChangeEvent) { BindingContext lBindingContext = BindingContext.getCurrent(); BindingContainer lBindingContainer = lBindingContext.getCurrentBindingsEntry(); JUCtrlListBinding list = (JUCtrlListBinding) lBindingContainer.get("Status"); int newindex = (Integer) valueChangeEvent.getNewValue(); Object row = list.getDisplayData(); // Wichtig um die liste zu laden!!!! Row lFromList = (Row) list.getValueFromList(newindex); Object lAttribute = lFromList.getAttribute("Value"); String newVal = (String) lAttribute; }

How to get the values of the cells of an interactive report?
Hello
We use the APEX 4.0, with Oracle 10 g r2 on Windows XP.
I have a page with an interactive report, and I configured the "link" column to link to a target custom (instead of see a row).
This custom target is simply a call to a function of ajax (I hope!) view more information (in another region) on the clicked folder.
I think I have to display the primary key in the report and then get the value of call my function as:
to be able to find the information right on the straight line.javascript:my_function(ID);
But, how to get the value?
Kind regards.
Yann.Hello
Got to the report attributes tab and scroll down to the section of the link column. Click on the lightning bolt next to the column value, a popup displays Columsn names in reports of each locked in a pair of #.You pass the column for your javascript like this function
javascript:my_function('#ID#');
Kind regards

How to get the value on a model that is defined in the java code in email
Hello
I created a custom code and send email as well to custom component. I can send emails using the method:
InternetFunctions.sendMailTo (EmailID, EmailTemplate, subject, cxt);
But my problem is that I have to get a value in the model of "EmailTemplate" which are defined from java code. but I don't know how to get the value.
I will highlight in the java code by using this code: binder.putLocal ("ErrorApproveRejectMsg", massegeBody);
I'm trying to enhance the model using the code below, but not able to get.
1 < $exec getValue ("#active", "ErrorApproveRejectMsg") $ >
2 < $exec getValue ("#active", ErrorApproveRejectMsg) $ >
3 < getValue ("ErrorApproveRejectMsg") $exec $ >
4 < $exec getValue (ErrorApproveRejectMsg) $ >
5 < getValue ("#local", ErrorApproveRejectMsg) $exec $ >
6 < getValue ("#local", "ErrorApproveRejectMsg") $exec $ >
7 < $ErrorApproveRejectMsg$ >
8 < $exec ErrorApproveRejectMsg$ >
Assuming that cxt will be your Service or execution context object
You can do something like this
DB. PutLocal ("ErrorApproveRejectMsg", "Error");
cxt.setCachedObject ("DataBinder", db);
PageMerger h = new PageMerger (db, cxt);
cxt.setCachedObject ("PageMerger", h);
InternetFunctions.sendMailTo (usersEmail, emailTemplate, emailSubject, cxt);
where db is current databinder object, and you can put any variable custom in the workbook by using the putLocal method.
Thank you

How to get the value of a * Global * Application point of JS
If we declare an element of the request, which is NOT a level of the page in question, how we get the value of this element in an Action dynamic JavaScript on a page?
For example, we declare a "global" variable as an Application named DEFAULT_AJAX_SEPERATOR and set its value with a calculation of the claim "on the new Instance" a moment later, on a page of the application, we would like to get the value of DEFAULT_AJAX_SEPERATOR via JavaScript.
Page* level syntax element...
.. How does not work. I don't understand why it's like $v can only access the elements on the page. However, the APEX is clearly able to get these global values since, for example, they are available in PL/SQL blocks. Also, I know that it is on the session object, because I can see it when viewing the session.$v( 'DEFAULT_AJAX_SEPERATOR' );
So... What is sauce secret for obtaining this value?
Thank you
-JoeHello
Use something like this in your javascript code.var appItemVal = "& DEFAULT_AJAX_SEPERATOR.";
Thank you

How to get the value of PMT in oracle?
Hi all
I need to calculate the value of the PMT
There is the Excel PMT function == > PMT (rate, nPer, PV, (FV), (TYPE))
I have to calculate using pl/sql.
Can any body help how to get the value of PMT in PL/SQL?
Thanks for your help.
Kind regards
IwantoThere is no Oracle built-in function to calculate the payments, but the formula is easy to find. If you look at using Excel PV function, you should find the formula that excel uses to calculate. You can rearrange the calculation in terms of payment. If FV and TYPE are 0, then the calculation is
PV*rate*power((1+rate),nPer)/(power((1+rate),nPer) - 1)
You don't need really PL/SQL to do this.
Kind regards

How to get the values of page jspx (view layer) to the custom method defined in AM
Hello
I have 1 text field and 1 submit to homepage.jspx. When I click the button submit, it will call the custom method defined in the 'Module of the Application' java class (ApplicationModuleImpl.java). Can I know how to get the value of this text field in this custom method.
I used the getter and setter method, however it didn't work as it is defining the value correctly, but get method returns null. Its not allowing to use FacesContext. Could someone please tell me how to get the value of the text field to this custom method (that is, using ADFContext,... something like that)
Thanks in advanceUser,
you have mixed up something here. Bean (as you did) cannot use the module of the application. They belong to different layers.
I suggest you to look at some first tutorials (http://docs.oracle.com/cd/E18941_01/tutorials/toc.htm) or watch the developer guide http://docs.oracle.com/cd/E16162_01/web.1112/e16182/toc.htm and take a look at some of the videos http://www.oracle.com/technetwork/developer-tools/adf/learnmore/adfinsider-093342.htmlTimo
