Dynamic LOV of Oracle Portal

I am working on Oracle Portal reports, I need some dynamic LOVs
for the Query Screen. Could you tell me which version of Oracle
Protal provides Dynamic LOV functionality? My version is 3.7. If
3.7 does not provide this functionality, is there any way to do
dynamic LOVs?
Thans a lot!

You might try the Oracle9iAS Portal Applications forum for this
question.

Default value of combobox using dynamic LOV in Oracle Portal form

We are trying to specify the deafult value of a combobox on a form that derives it options from a dynamic LOV. The option value is a number and the display is text.
E.g.
<Option value="1">Books
<Option value="2">CDs
We have tried various ways of setting the default option to be selected on the Combobox. First, we tried using a sql query to return a number from a table (sql query returns number -> in the default value type field). Next, we tried to use a constant number (default value: 2, default value type: constant). In neither case, did the Oracle Portal form pre-select our default choice in the drop-down list.
Any suggestions? I browsed the other forum articles on this topic and noticed several folks believed it was a bug in Portal. We are using Portal version 3.0.9 (latest App Server for the Ebusiness Suite). Thanks in advance.

You can manually add the select list (or for that matter anything else) to a wizard created form. If the select list is for an existing item, simply change the "Display As" setting from Text to a Select List based on the LOV you create. Any changes made will then be applied by the update process.

Automated tool to convert from Forms to Dynamic Page for Oracle Portal?

Hi Experts,
We are thinking to convert majority of the forms in our portal to dynamic pages. Is there any tool to automate the conversion from Forms to Dynamic page for Oracle Portal 9.0.4.1.0?
Thanks, Abbas

Dear Abbas,
You seem to have two issues... ;-)
If you are finding the Forms are getting corrupt very easily, I'd suggest you go and open a Service Request into Oracle Support (http://metalink.oracle.com). There are a couple of ways where you can have these not corrupted (depeding on the Portal version you are in) and if there isn't yet a way you may get a bug logged and fixed within the next patchset eventually (improving the product functionality).
As to changing it to a dynamic page it might give you a bit more flexibility... yeah. It really depends on what you desire to do. I'd slowly start to code them in this way if your goal is this. As to the former coded forms unfortunately as I've said there isn't a strait way to do that, so you may do this slowly in time...
I hope it helps you a bit further...
Cheers,
Pedro.

Querying a Worksheet from PL/SQL Dynamic Page in Oracle Portal

Is there a way to actually ask Discoverer to give me a list of values for a report property from outside Discoverer?
In my case, I am trying to add reports to Oracle Portal via the Worksheet Portlet but I want to build a select list that contains valid entries for discoverer to run through the portlet for a discoParameter value. Is there any better way to get the list of values other than running the report's query 2x (once in discoverer to load the report and once in portal to get the list of values)?

Hello David,
This is not a feature for Discoverer Portlet but as far as I can see Oracle Portal has Page Parameter Form that migh help in creating dynamic list of values. Please check in MetaLink :
Note.292521.1 How to Create a Page Parameter Form with Dynamic LOV
Once the Parameter has been created, it can be used from Discoverer Portlet too :

How to write a dynamic SQL in Oracle Portal

Hello
I am running portal on instance C.
I have instance A and B
From instance C I want to run a report where I will select the instance name.
then the when I execute the query must be dynamically generated adn executed.
for example: in the case of instance A;
the query must be
select * from scott.emp@A
in the case of instance B
the query must be
select * from scott.emp@B
I already have database links A and B pointing to instances A and B respectively.
How do I achieve this. Any code samples, suggestions appreciated.
Thanks
Ganesh

Hallo,
I don't understand why you need a database link, if you are already on that instance ?
BUT for your solution : put your database links in a view and select from this view.
In the view you can do something like this :
create or replace view test
(col1, col2, col3)
as
select .., 'A' location
from taba@A
where ...
union
select .., 'C' location
from taba@C
where ...
union
select .., 'B' location
from taba@B
where ...
The only thing you have to do is to give the instance name to the view as the column location.
Good luck.

Oracle Portal Dynamic Pages?

I grabbed this from the Primer on Portlets "<b>By simply cutting and pasting the HTML provided by affiliates into Oracle Portal dynamic pages, you can create a portlet specifically for that affiliate program and embed it into your portal.</b>"
How is this Oracle Portal Dynamic Page created?

The dynamic page is a portal application component. You can create one within any portal application that you have been granted edit privileges (for a sample, go to the Navigator, click on the Applications tab and open EXAMPLE APP). For additional information, check out the on-line help (search for dynamic) or glance at the components section of the product features whitepaper: http://technet.oracle.com/products/iportal/pdf/portal_twp.pdf

Hi Everyone,
This was a known Issue in Oracle 9i AS Portal.I referred to the
metalink note ID 174116.1 which talks about the BUG No:1584284.and it gives some workaround to come across the BUG.
I got my dependent LOV work after changing the NUMBER datatype in the Procedure to VARCHAR2.(Then in the PL i converted the character to number by the SQL function.)

Dynamic lov on a apex page parameter form

I'm trying to create a dynamic lov on a apex page parameter form. I read another post to look at metalink note. 292521. I asked our DBA to review the note but he claims he can't find the article. he's also been unable to find the last 2 metalink requests i've made. can someone verify metalink note 292521 exists so i can inform the DBA?
Thanks,
Brian

Brian, I cannot find that note either, try posting your question in the APEX forum, this forum is for Oracle Portal questions.

Dynamic LOV based on Current user

How do i make a dynamic LOV based on the user id of the current user.
Also how to insert values from a form into a database
Can anyone please help me out.
Thanks

Use portal.wwctx_api.get_user to get the currently logged in userid.
The simplest example of a form manipulating data is to create the form based on a table. All DML works automagically. You can base your form on a procedure with dummy columns and do your own DML if you wish. Lots more flexibility that way...

Dynamic lovs in parameter forms ... Is this possible?

Hi
I am using report developer 10g on windows xp.
I need a cascading prompt style dynamic LOVs in my report parameter form.
The first LOV displays a set of values (say for eg. dept list). The second LOV will display another list, based on the value chosen by the user in the first LOV (Eg. List of employee names in that dept).
My first LOV select statement may look like below for the user parameter say P_DEPT
select deptno from dept;
My sencod LOV select stmnt may look like below for the user parameter P_EMP
select ename from emp where deptno = :P_DEPT
Each time I try to set the second LOV, report developer complains "Bind variables not allowed in select statement"
Same error msg comes if I reference the first user parameter(P_DEPT) as a lexical parmaeter.
How do I acheive the above in report parameter form? Any help is appreciated greatly...
Thanks

Hi Brad,
Thanks for the reply. I had almost given up hope on receiving replies to this message.
I do agree that it is simpler (and a lot striaght forward) to just use forms to develop dynamic LOVs of cascading prompt style, that is required in my app. But in our shop, we have integrated forms and reports in such a way, that all the report parameters are handled by report developer's own parameter form, rather than coding a separate logic on the forms side to handle the report parameters(as this has to be done on the forms side for every report that we generate, We thought it would be better to use the reports developer to handle the parameter input and then pass the .rdf to forms app). Currently in all our app, the parameter form generated by the report developer is rendered as HTML form on the browser (when the concerned rdf file is called within the forms app) and by submitting this we get the report output)
Hence I am very keen to get this done somehow on the report developer side.
I do hope I get some input on this. Also, its a little surprising that such a simple feature is not readily avalibale in the report parameter form. I hope oracle report developer team is reading this message...:)
Thanks

Custom DB authentication to an application from Oracle Portal not working.

Hi All,
We have a Portal customized and integrated to LDAP for SSO.
From the portal, we have a link that takes to another custom application that requires another level of authentication. We have implemented this authentication as custom Database based authentication.
When user login to the portal and access this link, he will be directed for authentication again. This custom application has been installed on a different OC4J instance while Oracle Portal is running in a different OC4J instance.
Issue is though user details are being propagated to the custom application page, we are receiving an error saying authentication failed.
In the OC4J instance specific for this custom application, we have configured jazn.xml to use custom authentication.
Below is the code:
<?xml version = '1.0' encoding = 'UTF-8' standalone = 'yes'?>
<!DOCTYPE jazn PUBLIC "JAZN Config" "http://xmlns.oracle.com/ias/dtds/jazn-9_04.dtd">
<jazn provider="XML" location="./jazn-data.xml" default-realm="jazn.com">
<property name="role.mapping.dynamic" value="true"/>
<property name="custom.loginmodule.provider" value="true"/>
</jazn>
and in jazn-data.xml, we gave the role mapping.
But the problem is when the link to the custom application is accessed, it seems like the custom autentication mechanism is not working.
Can anyone throw light on this?
Do we need to give the same configuration in the j2ee/home/config directory files also?
Can we use both LDAP and custom DB authentication with in the same OAS setup. Remember as of now, Portal and custom application are running in different OC4J instances but within the same OAS.
Any help in this regard will be highely appreciated.
Thanks,
Sasi Bhushan

Dynamic LOV in a Tabular Form

Can somebody please tell me if there is a easy way to code a
dynamic LOV in a Tabular Form?
I need the ability to access a column value in the table row, to use in the WHERE clause of LOV query for another column in the row? Seems
like that should be easy , but not finding an answer.
Thanks for any help.
Carol

Hi Carol,
You can add the select list's definition directly into your SQL statement using APEX_ITEM.SELECT_LIST_FROM_QUERY - see: [http://download.oracle.com/docs/cd/E10513_01/doc/apirefs.310/e12855/apex_item.htm#CHDIDGDA]
If you first run your page with your existing select list on it, then do a View Source and look for the select list, you will see a "name" attribute of something like "f01" or "f02" etc. Make a note of the number part of this.
Then update your SQL statement to include the above and using the number you noted as the Index value (say, 4):
SELECT EMPNO,
ENAME,
DEPTNO,
APEX_ITEM.SELECT_LIST_FROM_QUERY(4,MGR,'SELECT ENAME d, EMPNO r FROM EMP WHERE DEPTNO = ' || DEPTNO || ' AND EMPNO <> ' || EMPNO) MGR
FROM EMPThat would give you a select list of employees in the same department as the current employee (excluding that employee themself)

Select item on a Tabular form with a different dynamic LOV on each row

I would like to use a tabular form where one of the columns is a dynamic LOV based Select, and where that dynamic LOV refers to one of the column values on each row.
So if the tabular form represented a list of teams and the LOV-based Select column was the current team leader, I would want that select list to be populated only with the members of that team (different for each row). Since the list of team members is in some other table (all_players or something) I would want to populate the LOV with a query with a where clause that selected only those players records with a team-membership equal to the current tabular form's team id. So, on each row that select list's contents would be different.
-- Justin

I'm beating a dead horse here but I did get something to work with "less" code. My current needs do not require me to cascade drop downs, I only want 1. You can use the query like the in the first reply (but I don't have a table with joins) I created a simple two column table dept_emp with 4 records 10,null 20,null .... I want to fill the nulls with an employee but ONLY an employee that matches the dept. (Same concept of team leader and members).
Here's the query:
select apex_item.display_and_save(1,dept) dept,
apex_item.select_list_from_query(2, name, 'select ename from emp where deptno='||dept) name
from dept_emp
I removed the code that was there already (ApplyMRU) and just put in this code:
BEGIN
FOR i IN 1..HTMLDB_APPLICATION.G_F01.COUNT LOOP
UPDATE dept_emp
SET
name=HTMLDB_APPLICATION.G_F02(i)
WHERE dept=to_number(HTMLDB_APPLICATION.G_F01(i));
END LOOP;
END;
The G_F01 matches the column 1 and so forth. There's more documentation but little explanation at:
http://download.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/api.htm#sthref2171
The thing I could not get to work was a dynamic message
#MRU_COUNT# row(s) updated, #MRI_COUNT# row(s) inserted.
Not sure when the MRU_COUNT gets populated (probably in the routine I removed ;))
You're probably way past me by now but I like to have as little code as possible when it comes to maintaining an app. That's why I liked oracle forms so much. This kind of stuff was pretty easy to do.
Thanks again everybody!

Problem - Creating a Dynamic LOV using duplicate value in select statement

I am trying to create a Dynamic LOV by attempting to follow a pattern similar to the following:
select shop_name d, shop_id r
from shops
order by 1
However, I want to use the shop_name twice as in the following because I do not have any other unique identifier available such as a shop_id to associate with the shop name:
select shop_name d, shop_name r
from shops
order by 1
But I get an error where I am not allowed to duplicate the shop_name in the select statement. I read somewhere on this forum where it can be done but I can't find exactly how.
Can someone tell or show me how to accomplish this?
Thanks in anticipation for your answer.
Thanks,
Ric

Ric,
I just tried to do this on APEX 3.0, and it worked just fine with this SQL:
select ename d, ename r from emp order by 1Perhaps you could put an example on apex.oracle.com or specify the error message that you're getting.
So as long as you have uniquely aliased both columns, this should not present a problem.
Thanks,

Dynamic LOV on portlet

I have a dynamic LOV as the only item in a portlet. The page is a 2 column layout with 2 tabs. When I click on the second tab I get 'There is currently no HTML content' message where the LOV should appear. Why?

Hi, I'm using Discoverer portlet on my Portal. As far as I know you need to map your form parameters to the page parameters and page parameters to Discoverer Portlet parameter. (Form > Page > Discoverer). There seems to be no direct way to pass parameters to Discoverer portlet.
Can you explain how did you build Custom Form with dynamic LOV and use session variables. I tried but I was unable to do so.
Please, provide steps to do the task. This would be of great help.
Thanks in advance.
