LOV returning 2+ values

Hi team,
How can I return TWO (or values) using Select List with dynamic LOV ?
so how to amend:
select name d, name r
from table
--> to also return "id" into to column id of table_2 ???
TIA
Bernhard

Bernhard,
I don't know of a way to do this with HTML DB's LOVs
I think your best option is to take a look at this How To:
http://www.oracle.com/technology/products/database/htmldb/howtos/how_to_create_custom_popups.html
It describes how you can construct custom pop up pages that return as many values as you wish.

Can a single LOV return values to two different fields?

Hi,
I have a scenario where I already have a LOV in the form which is assigned to a Field A. This LOV returns the value to field A. I have another field B which needs the same list of values. I can assign the same LOV to the field B as well, but can the value selected be returned to B?
I can create another LOV with the same record group, but just wanted to know if its possible to use the same LOV again.
Thanks

Hi Karuna,
You can achieve this by providing a third column in LOV (whose column width can be set to 0 to prevent it from being visible in lov) which can be comma-separated of two fields. This third field can then be assigned to the form field. And a substr() function call can get you both values.
Hope this helps,

[UIX] How To: Return multiple values from a LOV

Hi gang
I've been receiving a number of queries via email on how to return multiple items from a LOV using UIX thanks to earlier posts of mine on OTN. I'm unfortunately aware my previous posts on this are not that clear thanks to the nature of the forums Q&A type approach. So I thought I'd write one clear post, and then direct any queries to it from now on to save me time.
Following is my solution to this problem. Please note it's just one method of many in skinning a cat. It's my understanding via chatting to Oracle employees that LOVs are to be changed in a future release of JDeveloper to be more like Oracle Forms LOVs, so my skinning skills may be rather bloody & crude very soon (already?).
I'll base my example on the hr schema supplied with the standard RDBMS install.
Say we have an UIX input-form screen to modify an employees record. The employees record has a department_id field and a fk to the departments table. Our requirement is to build a LOV for the department_id field such that we can link the employees record to any department_id in the database. In turn we want the department_name shown on the employees input form, so this must be returned via the LOV too.
To meet this requirement follow these steps:
1) In your ADF BC model project, create 2 EOs for employees and departments.
2) Also in your model, create 2 VOs for the same EOs.
3) Open your employees VO and create a new attribute DepartmentName. Check selected in query. In expressions type (SELECT dept.department_name FROM departments dept WHERE dept.department_id = employees.department_id). Check Updateable always.
4) Create a new empty UIX page in your ViewController project called editEmployees.uix.
5) From the data control palette, drag and drop EmployeesView1 as an input-form. Notice that the new field DepartmentName is also included in the input-form.
6) As the DepartmentName will be populated either from querying existing employees records, or via the LOV, disable the field as the user should not have the ability to edit it.
7) Select the DepartmentId field and delete it. In the UI Model window delete the DepartmentId binding.
8) From the data controls palette, drag and drop the DepartmentId field as a messageLovInput onto your page. Note in your application navigator a new UIX page lovWindow0.uix (or similar) has been created for you.
9) While the lovWindow0.uix is still in italics (before you save it), rename the file to departmentsLov.uix.
10) Back in your editEmployees.uix page, your messageLovInput source will look like the following:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="${bindings.DepartmentId.path}"
    destination="lovWindow0.uix"/>Change it to be:
<messageLovInput
    model="${bindings.DepartmentId}"
    id="DepartmentId"
    destination="departmentsLov.uix"
    partialRenderMode="multiple"
    partialTargets="_uixState DepartmentName"/>11) Also change your DepartmentName source to look like the following:
<messageTextInput
    id=DepartmentName
    model="${bindings.DepartmentName}"
    columns="10"
    disabled="true"/>12) Open your departmentsLov.uix page.
13) In the data control palette, drag and drop the DepartmentId field of the DepartmentView1 as a LovTable into the Results area on your page.
14) Notice in the UI Model window that the 3 binding controls have been created for you, an iterator, a range and a binding for DepartmentId.
15) Right click on the DepartmentsLovUIModel node in the UI Model window, then create binding, display, and finally attribute. The attribute binding editor will pop up. In the select-an-iterator drop down select the DepartmentsView1Iterator. Now select DepartmentName in the attribute list and then the ok button.
16) Note in the UI Model you now have a new binding called DCDefaultControl. Select this, and in the property palette change the Id to DepartmentName.
17) View the LOV pages source, and change the lovUpdate event as follows:
<event name="lovSelect">
    <compound>
        <set value="${bindings.DepartmentId.inputValue}" target="${sessionScope}" property="MyAppDepartmentId" />
        <set value="${bindings.DepartmentName.inputValue}" target="${sessionScope}" property="MyAppDepartmentName" />
    </compound>
</event>18) Return to editEmployees.uix source, and modify the lovUpdate event to look as follows:
<event name="lovUpdate">
    <compound>
        <set value="${sessionScope.MyAppDepartmentId}" target="${bindings.DepartmentId}" property="inputValue"/>
        <set value="${sessionScope.MyAppDepartmentName}" target="${bindings.DepartmentName}" property="inputValue"/>
    </compound>
</event>Thats it. Now when you select a value in your LOV, it will return 2 (multiple!) values.
A couple things to note:
1) In the messageLovInput id field we dont use the .path notation. This is mechanism for returning 1 value from the LOV and is useless for us.
2) Again in the messageLovInput we supply _uixState as an entry in the partialTargets.
3) We are relying on partial-page-refresh functionality to update multiple items on the screen.
Im not going to take the time out to explain these 3 points, but its worthwhile you learning more about them, especially the last 2, as a separate exercise.
One other useful thing to do is, in your messageLovInput, include as a last entry in the partialTargets list MessageBox. In turn locate the messageBox control on your page (if any), and supply an id=MessageBox. This will allow the LOV to place any errors raised in the MessageBox and show them to the user.
I hope this works for you :)
Cheers,
CM.

Thanks Chris,
It took me some time to find the information I needed, how to use return multiple values from a LOV popup window, then I found your post and all problems were solved. Its working perfectly, well, almost perfectly.
Im always fighting with ADF-UIX, it never does the thing that I expect it to do, I guess its because I have a hard time letting go of the total control you have as a developer and let the framework take care of a few things.
Anyway, I'm using your example to fill 5 fields at once, one of the fields being a messageChoice (a list with countries) with a LOV to a lookup table (id , country).
I return the countryId from the popup LOV window, that works great, but it doesn't set the correct value in my messageChoice . I think its because its using the CountryId for the listbox index.
So how can I select the correct value inside my messageChoice? Come to think of it, I dont realy think its LOV related...
Can someone help me out out here?
Kind regards

Return multiple values from dynamic lov in apex 3.2.1

Hi
I need to create a dynamic lov that displays multiple values from a table and RETURNS multiple values into display only fields in a form page to be saved to the database
For example
dynamic list of value name SERVER
select name || ',' || life_cycle d, name r
from sserver
order by 1
This SERVER LOV is attached to the P4_SSERVER_NAME field in the form.
However this only returns sserver. name into the P4_SSERVER_NAME field in the form. I would need to capture the life_cycle field as well and populate the P4_LIFE_CYCLE field in the form as well. How does one do this?
I have searched this forum however could not find a thread that fit my situation. i saw that in 4.2 there is dynamic action however unable to upgrade at this moment.
any suggestions are greatly appreciated.
thank you

Hi CRL,
One method is to set the value of your P4_LIFE_CYCLE item via APEX_UTIL.set_session_state
To do this you need to create a Page Process
Type PL/SQL anonymous block
Process Point On Load - Before Header
The source for the Process might look like this: DECLARE
   l_life_cycle   VARCHAR2 (50);
BEGIN
   SELECT life_cycle
     INTO l_life_cycle
     FROM sserver
    WHERE :p4_sserver_name = sserver.name;
   APEX_UTIL.set_session_state ('P4_LIFE_CYCLE', l_life_cycle);
END;Jeff

Return multiple values for the popup LOV

Hi folks,
I have one challange. I have a search engine and there is an popup lov and its having three Display and 3 Retun value such as
select
p.A || ', ' || pi.B|| ', ' || km.C|| ' ' d, p.A || ', ' || pi.B|| ', ' || km.C|| ' ' r
from tableA km,tableB p,tableC pi
where km.col1=p.id and km.col1=pi.id and km.C is not null
when i click on the pop lov it will display 3 values shuch as SAP+DBA+HR and in popup lov iteam its will return 3 values
such as SAP+DBA+HR this return values are from 3 cloumn names from same table ie. A column, B column, C column
and when i click on submit button this return values from 3 columns values should assign to the 3 column such as
A=SAP, B=DBA and C=HR and search fetchs the result in a Report.
Its some thing new, is it possible..:)
ok will be waiting for your reply..:D

Hi Varad,
am facing problems i wrote dynamic sql its working fine for 2 and 3 fields like (SAP+ORCL) and (SAP+ORCL+HRA) but for the single value like SAP the results are not comming properly. my code is
If (:P25_TEST Is not Null ) THEN
V_Sql := V_Sql||q'!
And
(multipleInstr1(R.Pillar,:P25_TEST)>0 )
or INSTR ( '+' || Upper(:P25_TEST) || '+', Upper(R.Pillar))>0 ) and
((multipleInstr1(R.Product_Line,:P25_TEST)>0 )
or INSTR ( '+' || Upper(:P25_TEST) || '+', Upper(R.Product_Line))>0) and
((multipleInstr1(R.Category,:P25_TEST)>0 ) or (R.Category is null)
or INSTR ( '+' || Upper(:P25_TEST) || '+', Upper(R.Category))>0 )
End If;
where multipleInstr1 is a function created to search results even its delimited by '+' it ignors '+' delimiter and
:p25_test is the popup iteam which takes values like SAP+ORCL+HRA or SAP+ORCL or SAP how its possible to get this results.
Its turning too complicated for cheking condetion for a single popup iteam, can we get any solution for this or not..
Hope will do respond
Thanks and Regards,
Suri

How can a LOV returns more than one value in ADF query?

Hi,
I'm using JDev 11g .I'm using a LOV attribute and I have declared a transient attribute to return the meaningful value of the LOV on it. Now it works fine in form , but I want to make it work on the view criteria(<af:query>). It does not return the transient content, and returns empty value.
Thanks

Returning a value from a LOV to the main document

Hi,
I'm using jheadsrart with uix, I have a form with a LOV. When I chose a value in the LOV, I need to return another value from that LOV to a hidden field in my main document.
How can I do that?
Thanks for your help!
Martin

Hi Rohit,
Just declare the two variables var1(variable for checking data) & var2(variable for counter) in your include program.
Inside the include you can do the coding as under:
IF VAR1 <condition for checking data>.
VAR2 = VAR2 + 1.
ENDIF.
Now you can check the value of the variable VAR2 in the main program & call the desired function.

Chetan.

Apex 2.2 popup lov doesn't return chosen value

Hey,
I've built a page within one of my applications in apex 2.2 that has an item based on a Popup LOV. I have a pre-built dynamic LOV.
When I run the page the popup icon appears and I can launch the popup. The filters work, and the result set appears. However, if I attempt to click on a value, nothing happens. The window remains opened and no value is returned to the parent window. The browser window shows no sign of javascript errors.
I'm using Theme 11 and the standard popup template.
I've tried this is a different workspace, using the same lov sql etc, and it works ok!
I've tried it elsewhere in a new page within my problematic application, and the problem is replicated there too.
What could be going wrong?
Cheers,
John

I feel that , it's like your error.
could you please help me ou.t

LOV does not return the value (2)

PPR in general does not work correctly if invalid HTML is generated. One example of an invalid HTML is having an opening <TD> tag immediately following another opening <TD> tag.
After checking everything else, if LOV still does not return the value, test whether it's not a problem with the invalid HTML by placing the messageLovInput outside of the complicated layout nestings you may have. If it works outside of the layout nestings, look for the possible problems in the layout nestings.

LOV problem ... returning display-value and not key-value

Hi. Sorry for my broken English.
I have a problem with pop-up dynamic LOV.
I have a simple form called Form A containing item_code and item_name. Users can create, update and delete new item by using this form.
Another form called Form B has a field called item_code, and the item_code field is a dynamic pop-up LOV field and a query for this LOV is like this;
select item_name d, item_code r from item_master order by item_code;
When i create the new record in Form B and use LOV to find and get the item code, LOV works fine
and it returns key-value to the item_code field.
But when i try to update the record (I have a link from report page to Form B), value of the item_code field is not the key-value from LOV, but is a
display-value from LOV.
Any ideas?
Thank you.

Well, from what you have described, this is working exactly as it should. Form B's LOV is intended to retrun the key value but should show the dispaly value. When you go from the report to the form, the key value is being passed (or should be depending on your code) and Form B ought to show the display value.
So, in short, I would say that Apex is doing what it should. Unless I misunderstand something.

Lov to return multiple values

I had a made a dynamic query "Select empno,empname from emp",
but it returns me only one value.In my main form i had 2 fields
EMP_NO and EMP_NAME.
How to get both the values through LOV.
Any advice.
Regards,
aakash

If your select statement is "Select empno,empname from emp" in the dynamic LOV you have created, then it means that the diaplay value is "empno" and the return value is "empname". Always, the first column selected is the display name and the second one is the return value for the dynamic LOV. You cannot return multiple values thru LOVs since forms will not accept currently. In your case, you need to have 2 LOVs... one for empno and the other for empname.

LOV not returning a value

I'm pretty new to Oracle Forms and have a problem where a LOV is not returning a value unless a bad/invalid value is entered in the form. If the field is null and I choose help/list the LOV appears but the selected value does not then populate the field. If I enter invalid data, when I try to leave the field the LOV appears and I can then successfully select a value and the field is populated correctly. I have the field set to "Validate from list". Any suggestions?
Bob

Yes. I did populate return value. What is odd is that the LOV works if I enter an invalid value. Because of the validate from list the LOV reappears and then when a value is selected it populates the field. I just will not work when the field is empty.

When LOV does not return the value

Check that you are not calling setText(String) on the web bean to set the default value. It causes your bean to no longer draw the value from the underlying VO. One of the symptoms is that selecting a value from the LOV modal window will not return that value to the base page. (The value from the LOV will actually be set on the VO, but the UI won't reflect it.)
Setting the default value in the model layer is prefered. You can do this by overriding the create(AttributeList nameValuePair) method of OAEntityImpl or OAViewRowImpl.
If, for some reason, you need to set the default value from the client side, you need to call setText with the pageContext, e.g., setText(pageContext, "myDefault");

Hello
Upon giving your question further thought I think that you would be better off if you added an 'id' column to table T1 and referenced this 'id' column in table T2 . Something like
Table_T1(id number, c1 varchar2(100)
and
Table_T2(.other_columns.. ,t1_id)
Your LOV will now be select c1 display,id return from table_t1The column t1_id will be defined to use this LOV.
You will need no other modifications to the form on table_t2

Avoid calling setText on the web bean to set the default value. It causes your bean to no longer draw the value from the underlying VO.

Strange Issue with Pop-up LOV with key value return

Hi,
I have a region, containing several LoV items. One of the items is of type PoP-up LoV with return key value.
Now when i run this page, i get page cannot be found error. But, If i a change the item type to select list with submit ( and not pop up lov with return key), I am able to run the page. It does not give me page cannot be found error.
Please suggest some pointers as to why I am running into this issue when item type is pop-up lov with return key value.
Regards,
Rave.
