Multiselect List selected by default

Hi, I have a Multiselect List populated with a LOV (elements in the "name" column of "TAB1").
I would like that if "TAB1"."check" = 1 the name into my Multiselect List was SELECTED when page is charged but I found nothing about that.
Do you have some suggestions ???
THANK YOU ...

Your solution is OK if my table is static but it isn't.
If I use static / sam:pet when I update table with a new item Multiselect is not updated.
I need to use the result of the query:
select name
from TAB1
where check = 1
and select these item into my Multiselect List where source code is:
select name
from TAB1
Something like:
DECLARE my_table wwv_flow_global.vc_arr2;
begin
SELECT name INTO my_table
FROM TAB1
WHERE check = 1;
FOR i in 1..my_table.count
LOOP
P1_SELECT.value (my_table(i)) = CHECKED;
END LOOP;
end;
I konw this code is not right but just to give you an idea of the way it has to work.
THANKS

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!

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 get multiselect list values

I have a multiselect list set up called :P_Staff_ID which uses a LOV (select staff_name, staff_id from staff)
to display staff names to the screen.
What function can i use to get all the selected names in the list for my submit process?
Thanks
Ray

Ray,
The selected values will be returned as a colon delimited list, e.g.: 20:30:40:50
You can use the htmldb_util.string_to_table function to convert it to something a more suitable for inserting. This is the spec of the function from the documentation:
HTMLDB_UTIL.STRING_TO_TABLE (
p_string IN VARCHAR2,
p_separator IN VARCHAR2 DEFAULT ':')
RETURN HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
and a sample that loops over the values:
DECLARE
l_vc_arr2 HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
l_vc_arr2 := HTMLDB_UTIL.STRING_TO_TABLE('One:Two:Three');
FOR z IN 1..l_vc_arr2.count LOOP
htp.p(l_vc_arr2(z));
END LOOP;
END;

How to show first parameter value in drop down list as a default value dynamically in ssrs report?

Hi,
in my ssrs report i have two parameters, accounts and Manager ,there is a cascading between the accounts parameter and manager parameter, as per the cascading we will get managers names based on the account we selected in the accounts parameter,
my requirement is the first name in the mangers drop down list has to get selected as default value.
please help me with this, it is an urgent requirement.
Thanks in advance,
Naveen

Hi NaveenMSBI,
According to your description, you want to use cascading parameters in the report, if the accounts are selected when you preview the report, the first manager name will be selected from drop down list as the default value. If so, there can be two scenarios:
• If manager is single-valued parameter, we can get Available Values and Default Values from the same query as below. Then when the accounts are selected, the first manager name will be selected as default value.
SELECT managerName FROM table_name WHERE accounts IN (@accounts)
• If manager is multi-valued parameter, we need to use different query for Available Values and Default Values. In this case, please refer to Patrick’s solution.
For more information about Adding Cascading Parameters, please refer to the following document:
http://technet.microsoft.com/en-us/library/aa337498(v=sql.105).aspx
If you have any questions, please feel free to let me know.

FREE check box in PO should be selected by default for specific material

Hi All,
We have a check box FREE in PO creation - ME21N in the item row which is selected when ever we want the vendor to supply those items as free.
- I have a list ot items which are supplied freely by the vendor which I have to mention in the PO. My requirment is when ever the specific material is in the PO the FREE check box should be selected by default. Is it possible?
Please advice.
Thanks ,
Vengal Rao.

Hi Vengal Rao,
I don't think there's such flag in the material master. As far as I know any material can be supplied either free or chargeable - the buyer has to choose the applicable option it in each specific PO.
If however in your business case certain materials shall always be supplied as free, then you can use the BAdI that I mentioned above to analyse which material is being procured and set the FREE flag in the PO accordingly.

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.
FUNCTION delete_batch (v_batch VARCHAR2) RETURN varchar2

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

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.

A checkbox in a loop must be selected by default

Hi all,
There are two lists of checkboxes (in a loop), and one of the checkboxes list in the loop must be selected by default. I am trying to put the value of the checkbox to true but it is yeilding bizzare results... one of them being the checkbox doesn't get deselected sometimes...
Any help would be appreciated,
Thanks,
Deepu.

Even i have the same problem. Unable to figure that out. I have these checkboxes inside a loop and the name of the checkbox is being constructed dynamically using the loopIndex as follows
<SimpleTable>
<Field Loop....>
<Field name='tempFields.checkBox_4_$(loopIndex)'>
<Display class='Checkbox' />
<Default>
<s>true</s>
</Default>
</Field>
</End Field Loop>
</SimpleTable>
I am incrementing loopIndex by 1 for every iteration of the loop.
If i change the checkBox field name to be static (Ex: tempFields.checkBox_4_test) the checkboxes are being checked when the page loads..
Anybody any ideas as to why it is not working when using a dynamic field name.
Thanks

Disable Spark List selection indicator

How do I get rid of the Spark List selection indicator entirely? I don't want the rectangular indicator when the mouse hovers over an item, and I don't want the color to change when the mouse is clicked.

You'll have to extend default item renderer (ItemRenderer for instance) and set autoDrawBackground to false. And then use your item renderer in a list.
See this document for more information on spark item renderers.

How can I make JSF checkboxes selected by default?

Hi everyone,
I have a problem in setting default value for checkboxes. I use them in a table. tableRowGroup's sourceData property is a list data provider. In the page bean I have the following code to select rows:
private TableSelectPhaseListener tablePhaseListener = new TableSelectPhaseListener();
    public void setSelected(Object object) {
        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
        if (rowKey != null) {
            tablePhaseListener.setSelected(rowKey, object);
    public Object getSelected(){
        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
        return tablePhaseListener.getSelected(rowKey);
    public Object getSelectedValue() {
        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
        return (rowKey != null) ? rowKey.getRowId() : null;
    public boolean getSelectedState() {
        RowKey rowKey = (RowKey)getValue("#{currentRow.tableRow}");
        return tablePhaseListener.isSelected(rowKey);
    }I received a list of objects from a service using list data provider and use checkboxes to select them. Then I get the selected checkboxes in the action method of the page bean using
RowKey[] selectedRows = getTableRowGroup1().getSelectedRowKeys(); What I want to do is to set all the checkboxes as selected by default. Normally, this is performed by assigning the same values to selected and selectedValue properties of the checkbox component. But, in my case this is not applicable since we take advantage of getSelected() and getSelectedValue() methods in the pagebean. Properties of my checkbox component are as follows:
<ui:checkbox binding="#{MyPage.checkBox1}"
                                                    id="checkBox1" selected="#{MyPage.selected}" selectedValue="#{MyPage.selectedValue}"/>I cannot assign same values to selected and selectedValue. Can anyone help me to make these checkboxes selected as it is rendered?

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.
