Cascading select list (query based) in a tabular form

Hi,
In my application i have two select list in a tabular form one for selecting manager_id and other for selecting employees for the selected manager_id how can i do it in apex 4.0
thanks in advance

Ok i will assume that you have 2 select list items called (P1_MANAGER AND P1_EMPLOYEE)
In employee select list u need to find Cascading LOV Parent Item(s) and set it to P1_MANAGER. Ofc your sql query must be smth like this:
SELECT employee_name d, employee_id r FROM employee_table WHERE employee_manager = :P1_MANAGER

Tabular form (select list Query based LOV)

Hi all,
I have this situation:
a tabular form with two "select list (query based LOV)" fields.
The first one must affect elements in the second one. And so the second query based LOV field should has a "where attr1 = first_list_selected_value" in the query.
Is this possible ? Could you show me some advices ?
thanks in advance.

OK, thank you.
But maybe I wasn't too clear.
I need cascading LOV for each row of my tabular form.
I have a EMP tabular form
select
"ROWID",
"EMPNO",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "#OWNER#"."EMP" I need a Select List for DEPTNO for each record of table. After set a value, the second "Select List" for ENAME should be affected automatically.

Select List (query based LOV) in V. 4.1.1.00.23

Hi guys,
I am having some problems with an APEX application that I have exported from V. 4.1.0.00.32 and imported on V. 4.1.1.00.23.
I have a Tabular Form region where I have a column which is Display As "Select List (Query based LOV)".
If I add a new row - choose a new value (not the same as any of the above rows) and "Apply Changes"/"Submit" the value in the new row changes to the value of the 1. row of the tabular form :-( I can update this new row and then it saves the right value... It looks like it is only when inserting a new row.
Is this a bug or is it a feature ;-)
Hope you can help...

Leo,
Thanks for the response, but I don't think you quite understand my problem. If I go to the Column Attributes screen for the group_id field, I have the "Display As" drop down set to "Select List (query based LOV)", not "Select List (named LOV)". This requires that the sql query be written in the "List of values definition" text area below. Within that text area I have the following query:
SELECT DISPLAY_NAME, GROUP_ID
FROM APPLICATION_GROUPS
WHERE APP_ID = ?????
ORDER BY 1
The APP_ID that I need to reference is for the current row of data that is being processed. Therefore, I can't use a :PNNN_APP_ID variable, because that field does not exist on the page.
Hopefully this explains it a little better.
Thanks,
Kris

Select List (query based LOV) in a wizard created report form

I have created an updatable report form with 3 columns:
app_id
user_id
group_id
Each app_id has multiple group_id's associated with it, and I want to show the group_id field as a Select List (query based LOV) that contains the groups associated with the app_id.
My query for the select list needs to be similar to the following:
SELECT DISPLAY_NAME, GROUP_ID
FROM APPLICATION_GROUPS
WHERE APP_ID = ?????
ORDER BY 1
The problem is, I don't know how to reference the app_id from the main report to replace the ?????.
In other words, if my report returns 2 rows of data like this:
app_id----------user_id----------group_id
1-----------------24------------------3
2-----------------24------------------15
Then how do I get the group_id column to be a select list of possible groups for each application? If app_id 1 has 3 groups associated with it, 3, 4, & 5 and app_id 2 has 2 groups associated with it, 15 & 16, then those each of the select lists should be based on the app_id.
Hopefully I explained this clearly.
Thanks,
Kris

Character string buffer too small (select list query based LOV)

Hi,
Using the select list query based LOV with a select witch is too big, you get this error.
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
When using the Popup LOV query based LOV) then it works nice.
Can that be solved somehow?
With the Popup LOV the return value is displayed in stead of the description.

Hi Andy,
How do I incorporate your suggestion on a report ?
Example : I have
select apex_item.display_and_save(1,column1,5) col1,
apex_item.display_and_save(2,column2,5) col2 ,
apex_item.popup_from_query(3, emp_name, 'select user_name, name empname from table2) col3
Table 2 is a long list , and I'm getting string buffer too small due to this.
Your suggestion with HTP is good but I'm not sure how to implement it for reports as I'll like the user to change the values with the select_list.
I'm not using forms as they want mulit-record on the same page.
Hope to hear back from you soon.
Thanks very much.

Select query based LOV for tabular form attributes

Hi HTMLDB Team,
Congrats u all for the new release of HTMLDB in htmldb.oracle.com.
I badly need a solution of the below problem.
Say , i have table called user_col_comments now i want to display the table_name ,column_name and comments in a tabular form.I displayed only one row for the tabular form.Now i create a select query based LOV for attribute table_name where i got all table_name in drop down list.
Point is that after selecting any data from drop down table list i want to get the corresponding fields to be populated in column_name attributes.How can i wrote the select query based LOV for the attibute column_name.
I wrote it as 'select column_name d,column_name r from user_col_comments where table_name=:TABLE_NAME Its not working?
Similarly i want same thing to display for comments after matching both table_name and column_name.
Any solution to get rid of those problem will be highly appreciable...
If u need my htmldb.oracle.com userid and password to solve the problem i will sure let u email it.
Cheers,
Eman

Using select list as default value in tabular form.

Hi,
I am using Application Express 4.1.0.00.32. I have two questions that are related.
I have a Select item *'P1_SELECT'* and a tabular form My Items.
Question 1. The My Items tabular form col1 Attributes are set Display As Text Field, and the Tabular Form Attributes are set Default Type = item(application or page item name), Default = P1_SELECT. I have checked the session state value is set on P1_SELECT ie. Fred. What I need to know is, why, when adding a row to the tabular form My Items does col1 not display 'Fred' as the default value from the select item P1_SELECT? I can change col1 of the Tabular form to be Display as Text (save state) and this will work. However that leads me on to:
Question 2. After adding say 3 rows to the form, I then change the select P1_SELECT value to Bob and Bob is now set in session state on the P1_SELECT item, but when I again add row to the form the value Fred is still the value not Bob. It seems that the tabular form keeps the default value as Fred and not Bob. How can I get this to look or work like:
col1_
Fred
Fred
Fred
Bob
Your help is needed.
Thanks.

Howard (DBA in Training) wrote:
Do you submit the page or set the value after changing the selection? If not, the display value seems to be Bob but the working value is still Fred. That's what you are seeing right? In the "Settings" section, what do you have for "Page Action when Value Changed". I've been using "Redirect and Set Value" because I was staying on the same page after the selection.
Additional info which might be helpful (or NOT). ====================
NOTE: I am just a novice's novice with APEX and I had much agony with Select Lists. It was challenging to have the Select List value displayed because there seem to be so many different sources of the Select List value, namely:
1) the current value in the session state
2) the value you can specify in "Source value or expression" in the "Source" section of the Select List item
3) the value you can specify in the "Post Calculation Compution" in the "Source" section of the Select List item
4) the value you can specify in the "Default value" of the "Default" section of the Select List item
[Now, if I've misdescribed any of these, remember, this is from a novice's perspective.]
It's like putting a clock (back) together. Get any of the pieces wrong and it will probably not work right.
I had an addiitonal challenge in that I wanted the same Select List displayed on multiple pages and for the currently selected value (from the former page) to already be set on the new page when it was displayed. What fun!
To see what I did here: http://apex.oracle.com/pls/apex/f?p=43250:101 login Dever/Ima9Dever
Remember, I'm doing many things you will likely not need to do. I iniitalized the Select List for the first time it displayed. I copied the Select List value from old page to new page by storing it in an application item F217_SYS_NIC_NM.
Best wishes,
HowardHi Howard,
You don't have submit the page for just setting one item's session state. you can use a Dynamic Action OR use Page Items to Submit property if available (this is available in various places such as sql region,chart region etc)
In context to this question you don't have to do any of those..just see my example above
Thanks

Select list in a manually created tabular form

I created a select drop down item in a manually created tabular form. When I run the page, it also shows the null value '%'. How do I edit this?
This is the line I am using in the SQL:
htmldb_item.select_list_from_query(34,IN_PGRS_STAT_DSC,'select distinct STAT_DSC, STAT_DSC from PROJECT_STATUS_REF') IN_PGRS_STAT_DSC,

And the select list doesn't work. It gives me an error message if I have the form to display one extra empty record and the select list. But even with the select list, if I don't include the extra row, it works properly.
report error:
ORA-06550: line 1, column 13:
PLS-00103: Encountered the symbol "COLLECT" when expecting one of the following:
:= . ( @ % ;
ORA-06550: line 1, column 82:
PLS-00103: Encountered the symbol ";" when expecting one of the following:
. ( , % from
What I also realized is that the drop down shows the value 7. But the table is empty with no records. I have no idea where this number 7 is coming from?

SELECT COUNTRY,COUNTRY_ID FROM CAP_PLAN_COUNTRY_DETAILS'Now, how can I fix this to use the Pole Id every time the country Select List is touched..Can I just modify the query or should I add a Java Script OnChange function to handle this...
Please please help..
Thanks for reading the question...

Isn't this given in my example:
http://apex.oracle.com/pls/otn/f?p=31517:176
The second list is extended by adding:
|| 'WHERE deptno = '
|| c001to make sure it renders correctly once you call your report. In your case the second list would be extended by adding the following
apex_item.select_list_from_query(33, COUNTRY_CODE_ID, 'SELECT COUNTRY,COUNTRY_ID FROM CAP_PLAN_COUNTRY_DETAILS ' || 'WHERE POLE_ID = ' || POLE_CODE_ID
, 'style=""', 'YES', '0', '- Select Country -', 'f33_'
|| LPAD (line_no, 4, '0'), NULL, 'NO' ) COUNTRY_CODE_ID,and that should work.

can anyone provide me with an example of the cascading select list.
can anyone help me out with cascading select list.
thanks.

Aplication item is always hidden - Shared Components > Application Items. You can create only one item and that would also be enough. For transparency purposes I said to create two. However, one will do the job.

How to populate another page item based on cascading select lists?

Oracle 10gXE
APEX 3.2
I've created cascading select lists based on the examples (using Javascript and AJAX) that i've seen on this forum. Thanks for help on that!
Now that I have these LOV's being populated without needing to submit the page, how do I take the value that is presently in each LOV and concatenate them together to populate another page item? I'm trying to build the URL string that will execute an Oracle Report once the user clicks a button.
Previously, when I had multiple Select Lists with a submit, the URL was being put together using an After Submit Computation that would set the value for an item (P26_REPORT_URL) on the page. Notice that a report parameter (i.e. parameter name and Select List value) is only included if the user has provided a value. The page item that holds these values is then referenced by a button for URL redirect. The URL Target for the button currently is: javascript:popupURL('&P26_REPORT_URL.'), but will not work at the moment because P26_REPORT_URL page item is not changing based on what is selected in the LOVs. Since I'm not submitting anything (do I need to?), how do I put together the values needed?
Computation for P26_REPORT_URL:
DECLARE
l_param VARCHAR2(2000);
BEGIN
l_param := '&REPORTS_URL.&report=&P26_RPT_VIEW..rdf&desformat=&P26_DESFORMAT.&destype=cache';
IF REPLACE(:P26_OLO_CODE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_olo_code=&P26_OLO_CODE.';
END IF;
IF REPLACE(:P26_BEG_DATE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_start_dt=&P26_BEG_DATE.';
END IF;
IF REPLACE(:P26_END_DATE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_end_dt=&P26_END_DATE.';
END IF;
IF REPLACE(:P26_ORG_CODE_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_org_code=&P26_ORG_CODE_2.';
END IF;
IF REPLACE(:P26_FLAIR_ORG_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_flair_org_code=&P26_FLAIR_ORG_2.';
END IF;
IF REPLACE(:P26_BUDGET_ENTITY_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_agy_code=&P26_BUDGET_ENTITY_2.';
END IF;
RETURN l_param;
END;

Andy,
This is a great suggestion! After I posted, I started looking at a Javascript solution and figured it's probably what I had to do.
However, now the cascading select list no longer working for some reason after I added the function to concatenate the item values. When I remove the showReport() function the select list works again.
Here is what I have in the HTML Header portion of the page:
<script language="JavaScript" type="text/javascript">
function popupURL (url) {
w = open(url,"winLov","resizable=1,width=800,height=600");
if (w.opener == null)
w.opener = self;
w.focus();
function showReport()
var l_param = '&REPORTS_URL.&report=' + $v('P26_RPT_VIEW') + '.rdf&desformat=' + $v('P26_DESFORMAT') + '&destype=cache';
if ($v('P26_OLO_CODE' != '')
   l_param += '&p_olo_code=' + $v('P26_OLO_CODE');
if ($v('P26_ORG_CODE_3' != '')
   l_param += '&p_org_code=' + $v('P26_ORG_CODE_3');
popupURL(l_param);
function get_AJAX_SELECT_XML(pThis,pSelect){
     var l_Return = null;
     var l_Select = $x(pSelect);
     var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ORG_SELECT_LIST',0);
     get.add('TEMPORARY_ITEM',pThis.value);
     gReturn = get.get('XML');
     if(gReturn && l_Select){
         var l_Count = gReturn.getElementsByTagName("option").length;
         l_Select.length = 0;
         for(var i=0;i<l_Count;i++){
             var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
if(document.all){
pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);
</script>

Cascading Select list in tabular from

Looked at Denes example on Cascading Select Lists - http://apex.oracle.com/pls/otn/f?p=31517:119:2294401989620845.
Want to have the primary select list as an item in a region, then the secondary select list as
a column in a tabular form in the same region. Is this possible?
The Onchange event is placed in the HTML Form Element Attributes for a page item but a column on a tabular form doesn't have this.
Can the Element Attributes or Element Option Attributes be used to hold the OnChange event code?

Cascade Select list with Tabular Form

Hi,
I am trying to implement Cascade Select List functionality on a tabular form where users should be able to add multiple rows. The data should be saved to a temporary stage area, where users can review the data prior to saving to the table. Very similar to the shopping cart where one can Delete/Update rows by record. I believe there is a way to do it via APEX Collections. If anyone has an example it would definitely help. FYI, Running on APEX 3.2, so no built in cascade functionality.
Thank you,
Chandu

If you received a reply or figured out how to do this, can post? I need to implement exact same functionality and have not figured out how to do so. Have pinged Denes K. for source code on his demo app but not yet received response. Can this be done using wizard tab form or does it have to be a manually tab form?
