How to get a Value based on Foreign Key item

Hi,
I have two tables as below
TABLE 1
T1_COL1 NUMBER ---primary_key
T1_COL2 NUMBER ---foreign_key to TABLE2.T2_COL1
TABLE 2
T2_COL1 NUMBER ---primary_key
T2_COL2 VARCHAR2(40)
Table 2 is my reference table. I have created a form for table 1, however I want to show user the value of T2_COL2 all the time . My user is not interested in seeing primary key value data.
Can some please advise what is the best way to do this in APEX.
Thanks
Aali

Hello:
One way to do what you want done is to
1) On the form make the page-item corresponding to T1_COL2 a hidden item
2) Create a new page-item of type Display Only.
3) Set the Source Type for this item to be 'Sql Query'
4) In the Source Value or Expression enter the query select T1_COL2 from table_2 where t2_col1=:pxx_t1_col2Varad

How to get ATINN value based on material number and Class Type ?

I have below SELECT stmt code which gives the correct value of atwrt based on materil no and ATINN.
However in quality system, it is failing because in quality system "atinn" value is not 0000000381. It is different.
So how can I get ATINN(Internal characteristic) value based on material number and Class Type?

How to get input values till pressing enter key

hi!!!
i need to enter values thru keyboard using bufer reader etc etc
but i need to stop entering when i press enter key
how to do this??

First off I would take a look at this link because it gives quite a few good examples if you've never used scanner.
You can find all this on the link.-> http://java.sun.com/j2se/1.5.0/docs/api/java/util/Scanner.html
in order to use scanner you have to import it.
import java.util.Scanner;then inside your main method you need to create a scanner wrapped around the keyboard inputstream.
Scanner userIn = new Scanner(System.in);take a look at the api to decide which method you want. For this I would suggest nextLine().
also I would specify that you want the numbers separated by spaces or comma's or something so you can use the String.split(" "); method which returns an array of Strings;
then traverse through the array of strings and convert them to ints

The customer want to use particular F4 help on report, but some input value before press enter key are not used in event of "at selection-screen on value-request for xxx", How to get parameter value in this event?

How to Get Resource value which are referred in code behind file using IResourceProvider

Hi Everyone,
Currently I'm working on moving the Resource file from "App_GlobalResources" to Database by using IResourceProvider. I created a CustomResourceProvider project using ResourceProviderFactory and able to get the resource values from DB which
are used in aspx page.
But i'm not able to get the values which are referring from code behind file.
Ex: Label1.Text = Resources.Common.Car; // This is still coming from resx file.
Can any one please let me know how to get the value from DB instead of resx file which are referred in cs file.
Appreciate your help.
The below code uses the ResourceProviderFactory which calls this method and gets it from DB. Please let me know if you need any more info.
public class DBResourceProviderFactory : ResourceProviderFactory
public override IResourceProvider CreateGlobalResourceProvider(string classKey)
return new DBResourceProvider(classKey);
public override IResourceProvider CreateLocalResourceProvider(string virtualPath)
// we should always get a path from the runtime
string classKey = virtualPath;
if (!string.IsNullOrEmpty(virtualPath))
virtualPath = virtualPath.Remove(0, 1);
classKey = virtualPath.Remove(0, virtualPath.IndexOf('/') + 1);
return new DBResourceProvider(classKey);

How to get Datalink value in Ichart ( Flavor: Pie ) ?

Hi Jermy,
I can select the pen numner form selection event of the legend by using
document.<appletname>.getchartObject.getSelectedPen()
How can get the values assoiciated with that pen or legned ( i mean datalink vales ).
I have added one column in the datalink columns of the ichart template and i need that datlink values based on the legend selection.
How can i do that?
Thanks
Vansi

Vansi,
Leveraging the Script Assistant to help you with methods, and using the javascript alert statement are great ways to learn how the applet methods behave.
The .getDatalinkValue(PENNUMBER,POINTNUMBER,ATTRIBUTE) method has three inputs - you already know how to get the pennumber, and since your chart is Pie then the pointnumber should be 1 since you don't have a line chart or group bar chart. The attribute is a one-based index for all of your mapped datalink columns, so if you only have one of these then use a static 1.
Regards,
Jeremy

How to get the values from popup window to mainwindow

HI all,
   I want to get the details from popup window.
      i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

How to get return values from task flow in af:region ?

Hi!
I'm working with a taskFlow that is rendered inside a popup using the "popup inside a region pattern" (http://www.oracle.com/technology/products/adf/patterns/popupregionpattern.pdf), but now this taskFlow has an input parameter and a return value definition. So the question is how to get a value returned by this taskFlow thas is called inside a region?
Any suggestion?
Thanks in advance!

Hi,
write the value to a shared memory scope like session and read it in the regionNavigation listener. If you follow the paper you refer to then the listener determines of the viewId is null, this a return happens. It wuld then look in the memory scope for the return value.
Another option would be to use an object that you pass as an argument to the task flow you open in the popup. Then you change the object you passed in, which then makes the return information available in teh calling flow. The object you pass in would have to be in a shared scope too

How to get selected value from selectOneRadio ???

Hi...i want to how to get selected value from selectOneRadio and use it in another page and in backing bean.
Note i have about 10 selectOneRadio group in one page i want to know value of each one of them.
Plzzzzzzzz i need help

You have a datatable in which each row is a question, correct?
Also in each row you have 5 possible answers that are in a radio, correct?
So,
You need to put in your datatable model, a question, and a list of answers (5 in yor case) and the selected one.
So you will have a get to the question, an SelectItem[] list to populate the radios and another get/set to the selected question.
ex:
<h:selectOneRadio value="#{notas.selectedString}" id="rb">
<f:selectItem itemValue="#{notas.valuesList}"/>
</h:selectOneRadio>
Search the web for examples like yours.
