Ajax - Populate Multiselect List

I have a requirement to populate a multiselect list using Ajax. Does anyone of you know
how to acomplish that?
I would klick on rows in a report and pick the values from there and the values would be
concatenated to the existing content of a multiselect list item.

Hi Denes,
have a look at the code of the "List Manager" item type. I think that's exactly what you are looking for.

How to get the selected values from multiselected list

Hi,
I have a multiselect list displaying all the years from 2003 to 2008 (used dynamic LOV). The user can choose one or more years as per his needs, and then when user clicks on the link the selected values of the list are to be captured and a pop up page of a Discoveror report needs to be opened where these years get passed as a parameter. I tried several methods to capture the value, but either one or all are getting passed but not exactly what the user has chosen.
This is how it looks:
P2_FISCAL_YEAR is a multiselect list containing values from 2003,2004... 2008
If user chooses 2004 and 2007
then I want the url to capture these values and pass as parameters for my discoveror reports. as '&qp_fiscal_year=2004,2007'
Any help is appreciated!
Thanks in advance,
Sapna.

Multiselect list in APEX 3.2.1.00.12

Hello,
I'm having troubles with a multiselect list that could potentially return a very large result set. I have a function called 'GET_LIST' that basically calls the apex_util.STRING_TO_TABLE(p_string,p_delimiter); function since the multiselect list returns a colon delimited string. If I try to select all of the values on the list I get the following message:
Bad Request
The request could not be understood by server due to malformed syntax.Are there any known workarounds to this issue?
Thanks in advance!
~Jake

Do any pros out there have a suggestion for this? My multiselect list has over 35,000 entries in it for certain owners. It is doubtful that anyone would ever select them all but if they should happen to they would receive an error.
The list of values (P10_ACCTS) is simply
select a.account_name d, a.account_id v
           from accounts a
         where a.owner = :P10_OWNERI then display a report that uses the results of the select list in the where clause:
and (account.id in (select column_value from table (GET_LIST(nvl(:P10_ACCTS,'::'))))GET_LIST is defined as:
CREATE OR REPLACE FUNCTION GET_LIST (
   p_string      IN   VARCHAR2,
   p_delimiter   IN   VARCHAR2 DEFAULT ':'
   RETURN vc_array_1 PIPELINED
IS
    l_string     varchar2(32000);
    l_array     wwv_flow_global.vc_arr2;
BEGIN
   l_array := apex_util.STRING_TO_TABLE(p_string,p_delimiter);
   for i in l_array.first..l_array.last loop
      pipe row (trim(l_array(i)));
   end loop;
   return;
end;I believe that my limitation is the 'l_string varchar2(32000);' I need (in some cases) to be able to pass over 100,000 characters. I've tried converting GET_LIST to use a clob instead of varchar2 but have yet to be successful in implementing that approach.
THanks in advance!

IMovie says "Open iTunes to populate this list."

When I try to add a photo or song to my iMovie project, the program says "Open iTunes to populate this list." (In the photo section, it says "Open iPhoto...") Opening either program doesn't change anything.
I've reinstalled Lion and iTunes to no avail. I have also moved the "iTunes Music Library.xml" file to the desktop, and although iTunes creates a new file, the problem persists.
I get the same messages for iTune and iPhoto in other programs, including Mail and Garageband. The problem seemed to pop up when I was connecting my iPhone to the computer to send an iMovie iOS project to iTunes.
Please help.

Hi, I have this same issue. I'm not so sure how to remove the preference file from my media browser though. I don't even know what the media browser is. Any help would be very appreciated. I can't access my iTunes data from iMovie or Keynote.....likely other iLife and iWork programs as well.

After a a lengthy conversation with Apple Tech. ($20), my problem seems to be solves. The Iphoto problem solved by trashing the plist file. The Itunes was more involved. We had to create a new Itunes folder and import the files into the new folder; and then import the playlists.

ApEx How 2 turn a multiselect list value (eg. 1:2:3:4 ) into (1,2,3,4)

ApEx newbie here,
I'm trying to get the output of a multi select list into an in list of a sql query for a report. The error message I'm getting is report error:
ORA-01722: invalid number. (The inlist is a list of id numbers, and the data type for this column in the database is NUMBER)
I've got a page item called P3_x which is populated from a MultiSelect list. I learned that these come out as colon delimited strings. (found a reference to hidden items in a blog that helped me figure this out)
So I created a hidden item called P3_x_in_list which does this:
Select '('|| regexp(:p3_x,':',',')||')' from dual which turns this into a comma separated list, like so: (1,2,3,4)
I put this hidden item, P3_X_IN_LIST into the sql in my report region
So in the report my sql looks like:
select a, b, c
from t1
where id in: P3_x_in_list
and some_date between :P1_X and :P2_X
For some reason it throws an invalid number error when it runs. I haven't been able to find anything in the documentation or on the web that sheds any light on this. I'm hoping that there is a benevolent, experienced developer that can point me in the right direction. The debuging information from the page is below:
Here is the debugging information

Well, let's say you had a SQL statement like
select * from obj where object_id in 12345
where object_id is defined to be a number type.
Now, if you replace the literal '12345' with a bind variable and then bind "(1,2,3,4,5)" to this bind variable it will be clear why the SQL fails.
As for using pipeline functions it is pretty straightforwad
Here's an example
CREATE OR REPLACE TYPE vc_array_1 AS TABLE OF VARCHAR2 (50);
CREATE OR REPLACE FUNCTION get_list (
   p_string      IN   VARCHAR2,
   p_delimiter   IN   VARCHAR2 DEFAULT ':'
   RETURN vc_array_1 PIPELINED
IS
    l_string     varchar2(32000);
    l_array     wwv_flow_global.vc_arr2;
BEGIN
   l_array := apex_util.STRING_TO_TABLE(p_string,p_delimiter);
   for i in l_array.first..l_array.last loop
      pipe row (trim(l_array(i)));
   end loop;
   return;
end;
select column_value from table (get_list('1:2:3:4:5'));Your query can now be
select a, b, c
from t1
where id in (select column_value from table get_list(: P3_x_in_list)) )
and some_date between :P1_X and :P2_XVarad

How to populate multiple list items dynamically?

Dear members,
I have a form there are 3 list items i want to populate these from a record group by dynamically.
but i can be able to populate only one list item. the others give errors.
frm-41337 cannot populate the list from record group.
following is the program unit:
PROCEDURE POPULATE_LIST_WITH_QUERY
     (p_list_item in varchar2,
     p_query in varchar2)
IS
     cst_rg_name constant varchar2(30) :=
          GET_ITEM_PROPERTY(p_list_item,item_name);
     v_rg_id RECORDGROUP;
BEGIN
     v_rg_id := FIND_GROUP(cst_rg_name);
     if id_null(v_rg_id) then
          v_rg_id := create_group_from_query(cst_rg_name, p_query);
     end if;
     if populate_group(v_rg_id) =0 then
          populate_list(p_list_item, v_rg_id);
          copy(get_list_element_value(p_list_item,1),p_list_item);
     end if;
END;
i call this in the when-create-record

Hi again,
Did the popup work ?
For the list item , use the built-in add_list_element in a loop. Example : in the pre-form or when-new-form-instance trigger ,
clear_list('block_name.list_item_name');
for rec in (select column1,column2 from t_table order by 1 desc) loop
ADD_LIST_ELEMENT('block_name.list_item_name', 1, rec.column1, rec.column2);
end loop;
See you

Delete in database based on multiselect list values

Hi,
I have a selectlist in Apex and a function in the database to do some delete based on the selected value from the select list.
FUNCTION delete_batch (v_batch VARCHAR2) RETURN VARCHAR2
IS
BEGIN
IF v_batch like 'M%'
THEN
   RETURN ('A monthrun cannot be deleted');
ELSE
   DELETE FROM so_disco_pa
   WHERE batch = v_batch
   DELETE FROM so_batch_pa
   WHERE batch = v_batch
   COMMIT;
   RETURN ('Batch '||v_batch||' has been deleted');
END IF;
EXCEPTION
WHEN OTHERS THEN
    RETURN ('Batch could not be deleted');
END delete_batch;The package function is called when the delete button is clicked with following process:
BEGIN
DECLARE
x   varchar2(100);
BEGIN
x := pa_control.delete_batch (:P3_BATCH);
:F105_MESSAGE := x;
END;
END;Now I want to change the selectlist to a multiselect list so that multiple batches can be deleted.
How do I change my procedure and process to delete batches based on the selected values?
Thanks,
Diana

I got this so far, but only the first batch selected in the list is being deleted. The other selected batch values are not deleted.
Some help please.

BEGIN
T := apex_util.string_to_table(v_batch);
For I in 1..t.count loop

ELSE
   DELETE FROM so_disco_pa
   WHERE batch = t(i)
   DELETE FROM so_batch_pa
   WHERE batch = t(i)
   COMMIT;

Need to create an edit Page from a Multiselect List

I make one or more selections of values from a Multiselect List; I need to branch to another page in which I display all of the selected List items and two other columns (per item) that can be edited; i.e., this second page will look like one or more rows consisting of (1) List item, (2) value1 from a Table, (3) value2 from a Table. I need to be able to change value1 and/or value2 for any or all of the rows and have those changes reflected in the Database. (The List item is display only).
My question is: which construction wizard can I use for this second page? I can collect my List items in a PL/SQL Table, but how can I display them and their related columns so the column values are editable?

Thanks for the reply. I understand how to create Collections with the values I need to display and modify; however, I'm unsure which construction Wizard to employ to launch the Page ("Form based upon a Procedure", etc.)
I looked in the Tutorials for a "collection demo" and found these potential candidates: "Build an Issue Tracking System", "Create a Simple Survey Application", and "Serving Application Express Reports". Is it one of these? If not, please tell me where I can find the "collection demo". Thanks.

How to populate a list box linked to selection in combo box?

Hi All,
I am a beginner in Xcelsius. I am having problem on how to populate a list box based on the selection on my combo box.
I have a combo box and a list box. The combo box value consist of Countries. Values are:
Singapore
Indonesia
Thailand
When I select, for i.e. Indonesia, I want to populate the list box with all the Postal Code of Indonesia. When I select Thailand, i want to do the same.
Can anyone shed some lights on how to achieve this?
My spreadsheet data is as follow
Country         Postal Code
Singapore     680123
Singapore     680124
Singapore     680125
Indonesia     155123
Indonesia     155124
Indonesia     155125
Indonesia     155126
Thailand       333123
Many Thanks,
Harianto

Hi,
I am detailing the complete steps below:
In the combobox select the entire range of Country while seeing the records from the Combobox, Xcelsius will automatically show the unique values in the selection.
After that in the "Data Insertion" section for Combobox select the "Insertion Type" as "Filtered Rows" (please click on the question mark beside this option and it will show how the selection works).
In the source select the postal code, in the destination select the range which will be used as a data source for the list box.
This will resolve the concern. Please remember to select the question mark beside the "Insertion Type" option, it explains the working in specific details.
Best of luck.
Regards,
Gourav

Help with Multiselect List Item

Assuming one employee can work for multiple departments, I want to display the departments employee 7844 works for preselected in a multiselect list.
I am using the following query statement in a report region.
select htmldb_item.select_list_from_query_xl(1, deptno ,'select DEPTNO,DNAME from scott.dept ','MULTIPLE HEIGHT=25', 'Y',null,null,null,'Department',null) a from scott.emp where empno = 7844
The result I am seeing is a multiple multiselect lists with one department selected in each list.
How should I modify the query to get what I want?
Thanks

Multiselect List and Branches

Hi,
1. I understand that multiselect list problem has discussed here multiple times but I could not find any answer for my situation. May be someone can give me an advise.
I have a page that has 8 multiselect lists. A user makes his selection, presses button “Report” and gets redirected to the report page (say page A) that displays records according to the user selection. Report source on page A is PL/SQL function body returning SQL query.
I created the button “Report” with wizard (selected option Submit Page & Redirect to URL). Everything was working fine till report was created in the same browser window. But a customer wanted to have a report displayed as a new page. So I changed ”Optional URL Redirect” target from “No Target” as it was before to URL and inserted a call to the JavaScript as URL Target ( I use this approach on several other pages).
Now when a user presses “Report” button he is redirected to the page A but that page displays completely different set of records. It looks like multiselect lists values are not passed to the report on page A any more. What am I missing?
2. As I mentioned before a main page has 8 multiselect lists so SQL statement is very long and I will need to create a lot of different reports based on the selections in those multiselect lists .
Is it possible to create an Application Level Variable, pass “WHERE” part of the SQL statement into it when button “Report” is pressed ( button has setting Submit Page & Redirect to URL!) and then use it in the SQL report source to generate reports?
Thank you in advance.
Val

Scott,
Thank you for your reply.
At the moment I switched to the URL it stopped passing multiselect list parameters( I have javascript function in the HTML Header section and call this function from the button).
If I understand the problem correctly I do not submit page as it was before. Session window does not show any parameters.
The only reason I need this switch - create a report in a new window.

Query Regarding multiselect list

Hi,
I have a multiselect list having the names of columns of one of the table say "example" table. I want to select only those columns from the "example " table which the user has chosen from the multiselect list.
eg:
the multiselect list has the following entries say entr1,entr2,entr3
and my "example" table has 3 columns entr1,entr2,entr3.
If the user selects entr1 and entr2 from the multiselect list then , I want to select only entr1 and entr2 columns from my table ie "select entr1,entr2 from example"
I need to display those columns only in a report.
Is there any way to do it. Any input would help.
Regards,
Deepthi

You could have a dynamic query region where the column list is built using the value of the multiselect list.
declare
q long;
begin
q := 'select pk,';
q := q || replace(:P1_MULTI_SELECT,':',',');
q := q ||' from some_table where ....';
return q;
end;And choose the 'Generic columns, parse query at run-time' option under Region Definition.
An easier option would be to write a static query with all possible columns and simply put a PL/SQL condition on each column (Report Attributes/Column Attributes) to hide it if the column name/alias is not in the multiselect's value. Something like
instr(:P1_MULTI_SELECT,'COLUMN_NAME') > 0Hope this helps.
