Tabluar Form + Dynamic LOV

Hi expert,
I defined Popup LOV (query based LOV) for a column on Tabular Form Element in Column Attributes, and the following error occurs when accessing to the page.
Error in init lov: ORA-06561: given statement is not supported by package DBMS_SQL p_lov:wwv_flow_security.g_security_group_id:987715809494418wwv_flow_security.g_curr_flow_security_group_id:987715809494418 Unable to initialize query.
I am not sure if Popup LOV does not work on the type of Tabular form. Does anyone have any idea to resolve this?
Thanks,
Rui

Scott,
Thank you for the offer. For some reason, it was working on apex. I will try to find the difference on my settings.
Thanks,
Rui

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

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.

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!

Creating dynamic LOV in form builder 6i

Hi All,
I am new to form builder.
I want to create dynamic lov, means
Project type
Client
Work_type(thsi is also lov) ->> 1) Billable
Reason (this is also lov) ->> 1) Billable
Work_type(thsi is also lov) ->> 2) Non-Billable
Reason (this is also lov) ->> 1) Fresher
2) Project Manager
As shown above, Suppose the project type is client then I will select either "Billable" or "Non-Billable" value.
If I am selecting Work_type LOV as "Billable" then it should display "Billable" value in reason LOV
or if I am selecting Non-Billable value from Work_type LOV then reason LOV will display the list of value as Fresher and Project Manager.
Please help me, its very urgent.
Thanks in advance.
Regards,
Bluetooth

Bluetooth,
This can be accomplished by creating two seperate record groups; one for Billable and one for Non-Billable. Then - in the WORK_TYPE When-Validate-Item (WVI)trigger - when the value is "Billable" you assign the Billable Record Group to your LOV or if the value is Non-Billable, then you assign the Non-Billable record group to your LOV. Your Record Group queries must return the same number of columns and the column names must match. If your record groups need to have a different number of columns and column names, then I would just use two seperate LOV's and assign them to the item accordingly. For example:
/* Sample WVI trigger */
DECLARE
lov_id    LOV;
item_id   ITEM;
BEGIN
lov_id := Find_LOV('YOUR_LOV_NAME');
/* Option 1: Change Record Group of LOV */
IF ( :YOUR_BLOCK.WORK_TYPE = 'BILLABLE' ) THEN
    IF ( Get_LOV_Property(lov_id, GROUP_NAME) != 'BILLABLE_RG' ) THEN
      Set_LOV_Property(lov_id, GROUP_NAME, 'BILLABLE_RG');
    END IF;
ELSIF ( :YOUR_BLOCK.WORK_TYPE = 'NONBILLABLE' ) THEN
    IF ( Get_LOV_Property(lov_id, GROUP_NAME) != 'NONBILLABLE_RG' ) THEN
      Set_LOV_Property(lov_id, GROUP_NAME, 'NONBILLABLE_RG');
    END IF;
END IF;
item_id := Find_Item('YOUR_BLOCK.REASON');
/* Option 2: Seperate LOV's */
IF ( :YOUR_BLOCK.WORK_TYPE = 'BILLABLE' ) THEN
    IF ( Get_Item_Property(item_id, LOV_NAME) != 'BILLABLE_LOV' ) THEN
      Set_Item_Property(item_id, LOV_NAME, 'BILLABLE_LOV');
    END IF;
ELSIF ( :YOUR_BLOCK.WORK_TYPE = 'NONBILLABLE' ) THEN
    IF ( Get_Item_Property(item_id, LOV_NAME) != 'NONBILLABLE_LOV' ) THEN
      Set_Item_Property(item_id, LOV_NAME, 'NONBILLABLE_LOV');
    END IF;
END IF;Hope this helps,
Craig B-)

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.
cheers,
Ron

Dynamic LOV buttons in Forms

Hello:
The dynamic LOV button (app.ui.lovButtons=true) in Registry.dat setup is showing the LOV button in NORMAT Mode ONLY.
This does NOT get displayed when the form is in QUERY mode. Is there a way to display the LOV buttons irrespective of Query/Normal Mode?
Thanks
Bala

Anyone faced this issue before?

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

Dynamic LOV FOR TABULAR FORM 6i

Hi,
I have tabular form of two Items(ID,DESC) and I want to Populate LOV for item(ID) every record
and record_Group & SQL statments are stored in DB.
ACTION: when query in POST-QUERY Trigger get for every record in tabular form -- the stored SQL-Statment from table then put it into dynamic record_group and populate the dynamic LOV.
Please advice,
Thanks in Advance.

OK daniel
This form used for get reports
then header get the name of Report (Table-A) (report_ID),(report_desc).
then details for get the Parameters will send to report builder (Table-B) (detail_id),(report_id),(sql_stm).
so parameters may be need for example stock code so this record need to query from stocks table to get stock code and stock name.
next record for item Code so need to query from Items table to get the Item code and Item name
another report for employees so the user enter report code then when query and get in details block employee code and employee name.
so the lov will check if this record have query sql-statment or not if have execute it in the record_group then in lov
then go to the next record if sql_stm is null then no lov in this record and so on.
thanks..

Dynamic LOV on form in update mode

I have a link to a portal form that specifies the primary key as below:
Portal30.wwv_user_utilities.get_url(
'application.form_link',
'primary_id',to_char(id),
'_primary_id_cond','=');
This works well. I can access the form in update mode for the specified row. However, on the form I have 2 combo boxes: one is for make of vehicle and the other for model. The make combo box uses an lov derived from a simple table query. The model combo box is a dynamic lov using a query based upon the value of the model. When entering the form in update mode, it fails to set the make bind variable to anything, so the model is left blank with no options. How can I set the value of the make bind variable on the link so I can get the dynamic lov for the model to be populated correctly?
(I have already tried to add the model to the url link, to no avail).
null

Hi noor,
When I click the link button I am opening the userdefined form and filling the corresponding document number details manually.
Do you mean, you're filling the form, field by field???
If so you're doing it wrong. That way the form has no connection to the correct Database record and cannot update it.
The correct way is as follows:
Put a DocEntry field in your form and bind it to the DocEntry database field.
Set this field to NOT Visible by default.
When a user clicks the LinkButton, you change the form mode to FindMode, make the DocEntry field visible use the oForm.Items.Item("DocEntry").Specific.Value = "" method to set the correct value to the field (use the DocEntry number NOT the DocNum) and use the oForm.Items.Item("1").Click() to open the correct record.
Then the user can change the value it needs without errors.

Problem with dynamic LOV and function

Hello all!
I'm having a problem with a dynamic lov in APEX 3.0.1.00.08. Hope you can help me!
I have Report and Form application. On the Form page i have a Page Item (Popup Key LOV (Displays description, returns key value)).
When i submit the sql code in the 'List of vaules defention' box. I get the following message;
1 error has occurred
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
When i excecute the code below in TOAD or in the SQL Workshop it returns the values i want to see. But somehow APEX doesn't like the sql....
SELECT REC_OMSCHRIJVING d, REC_DNS_ID r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
returns_dns_lov_fn is a function, code is below;
CREATE OR REPLACE FUNCTION DRSSYS.return_dns_lov_fn (p2_dns_id number)
RETURN dns_table_type
AS
v_data dns_table_type := dns_table_type ();
BEGIN
IF p2_dns_id = 2
THEN
FOR c IN (SELECT dns_id dns, omschrijving oms
FROM d_status dst
WHERE dst.dns_id IN (8, 10))
LOOP
v_data.EXTEND;
v_data (v_data.COUNT) := dns_rectype (c.dns, c.oms);
END LOOP;
RETURN v_data;
END IF;
END;
and the types;
CREATE OR REPLACE TYPE DRSSYS.dns_rectype AS OBJECT (rec_dns_id NUMBER, rec_omschrijving VARCHAR2(255));
CREATE OR REPLACE TYPE DRSSYS.dns_table_type AS TABLE OF dns_rectype;
I tried some things i found on this forum, but they didn't work as well;
SELECT REC_OMSCHRIJVING display_value, REC_DNS_ID result_display FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
SELECT REC_OMSCHRIJVING display_value d, REC_DNS_ID result_display r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
SELECT a.REC_OMSCHRIJVING display_value, a.REC_DNS_ID result_display FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) a order by 1

I just had the same problem when I used a function in a where clause.
I have a function that checks if the current user has acces or not (returning varchar 'Y' or 'N').
In where clause I have this:
where myFunction(:user, somePK) = 'Y'
It seems that when APEX checked if my query was valid, my function triggered and exception.
As Varad pointed out, check for exception that could be triggered by a null 'p2_dns_id'
Hope that helped you out.

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

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...

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.)

QBE Report and Dynamic LOV

I have a QBE Report on a table "A" where the value of a field "F" is the "id", of another table "B".
For populating the table "A" I have create a form that uses a dynamic LOV (select name, id from B).
In the QBE report, the value of "F" is the id, instead of the "name". How can I display the name?
Moreover, if I "Update" a record, I would like to have (in the form for updating) the combobox with the complete LOV and NOT the text box with the id.
How can I do that?
thanks

Hi,
This happens in the case when a webview component has been added to a page and the mode selected is EXCEL. You see the excel dump on the screen.
This was a bug and has been fixed in 902.
Incase U want an excel report then you would have to use the RUN options available from the manage screen or navigator .This brings up a save option.You can open it or save the same and then open it.
Thanks,
Anu
