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

Using select list value as column name in SQL

Folks,
Thanks in advance for any help with this
I have a select list with two values (Instance and Username) created by
STATIC2:Username;USERNAME,Instance;INSTANCE
I am trying to pass the value of this (:P2_SELECT) and use it as a column name in a SQL query as below
select USERNAME,
INSTANCE
from table_name
where :P2_SELECT like '%'||:P2_TEXTSEARCH||'%'
When I substitue the :P2_SELECT for one of the values (either instance or username) this works fine
I suspect it is due to how Application Express interprets the value of :P2_SELECT
Any help would be much appreciated!
Gareth

Thanks Munky that worked a treat!
The next hurdle I have now is that because I have changed the region type to "PL/SQL Function(returning SQL Query)" there is no longer the option to add sorting to the columns as I have had to change the Source option to "Use Generic Column Names (parse query at runtime only)"
I will have a scout around and see how I can get around this

Need to use Select List value as column name

I want to have a WHERE ? IS BETWEEN ? AND ? clause.
I am using the PL/SQL Query returning a SQL Query as a report. This uses bind variables for items I had set on my form..... If I hardcode something like:
'WHERE STARTDATE IS BETWEEN '||
'TO_DATE(:P1_START,''dd-MON-YYYY HH24:MI'') AND '||
'TO_DATE(:P2_END,''dd-MON-YYYY HH24:MI'')';
I have no problem, but I have 2 date columns, STARTDATE and ENDDATE, and would like to use the value in a select list and not have to hardcode "STARTDATE" in there. I have not been able to do this, does anyone know how to use a bind variable as a column name? From reading some posts I think it might not be possible.

Heather,
You're on the right track, just glue in the column name so that it becomes part of the returned query string from the function (...'WHERE '||:COLNAME||' IS BETWEEN '|| ...).
Note that the bind variable is not part of the returned query string, but the column name obtained from the bind variable when the function executes does become part of the query string.

Select list that is dependent on another select list with ajax

I have a select list that contains it (ajax)
onchange = "get_select_list_ajax (this, 'P2012_REQUERENTE', 'COMBO_REQUERENTE_ITEM', 'COMBO_REQUERENTE_AJAX');" class = "largura200"
So I have a select list below, which is conditional, according to the value returned from the select list P2012_Cliente.
DECLARE
v_tipo VARCHAR2 (50);
BEGIN
SELECT DISTINCT (id_cliente_tipo) INTO v_tipo FROM vw_cliente
WHERE customer_id =: P2012_CLIENTE;
IF (v_tipo = pkg_cfg.c_tp_cliente_interno) THEN
RETURN true;
ELSE
RETURN false;
END IF;
EXCEPTION WHEN OTHERS THEN
NULL;
END;
But is not working .. Why? He is not detecting the return of the select list that is Ajax?

How can I send the return of a select list (ajax) on a text item?
html_form_attributes of sel. list -> onchange = "get_select_list_ajax (this, 'P2012_REQUERENTE', 'COMBO_REQUERENTE_ITEM', 'COMBO_REQUERENTE_AJAX');" class = "largura200"

Refresh PL/SQL Report Region (not Page) using Select List value

Hi,
I've got a report region based on a 'PL/SQL function body returning a SQL query'which gets generated on selecting a value from a Select list item, The Select List action is 'Redirect and Set value' but this causes the whole page to refresh rather than just the report region. I've tried to refresh the report only using a dynamic action on the Select List item (Action now reset to 'None') but now the report is not appearing on choosing from the List. Can anyone suggest a solution that will allow me to refresh this report without refreshing the page? I am using APEX 4.2.2 and the report syntax is as follows:
DECLARE
v_statement VARCHAR2(500);
BEGIN
SELECT query_text
    INTO v_statement
   FROM sql_queries
   WHERE query_id = :P2_QUERY ;
   RETURN v_statement ;
END ;
where P2_QUERY is Select List Item,
regards,
Kevin.

The report region being displayed is conditional on P2_QUERY item being NOT NULL. I assume the region not appearing is because the Action for the Select List Item is set to None and so P2_QUERY is always NULL.
No, the region is not appearing because it is conditional on P2_QUERY being NOT NULL. This means that the report region never exists on the page shown in the browser, so it can't be dynamically refreshed. (Dynamic refresh doesn't evaluate region conditions, and it only re-renders the report content, not the entire region.)
Remove the condition on the report region, check the refresh is working, then reconsider exactly what the requirements here are. If you want the region to appear only when P2_QUERY has a value, and you want it to be refreshed without submitting and re-rendering the page, then the region needs to be hidden rather than conditionally rendered, and shown via a dynamic action when P2_QUERY gets a value.
I tried adding an additional Set Value True Action for the DA event but got an error as listed above,
All irrelevant if Page Items to Submit on the region is used properly.

Using Select List value for building report

I have an interactive report form. I have a "After Header" (LOAD) process that run sql commands that will populate a table with the data that the report needs for a given week.
I have a Select List item that is run as a "Before Header" that gets a list of dates from a table. The dates only contain the first day of the week for the past two years. It is called "WEEK_OF" table and the column is called "WEEK_OF_DATE".
The default value for the Select List is the first day of the current week. And then all of the first day of the week from the WEEK_OF table.
I would like the LOAD process to use the value in the Select List. So at start up I would like the List to show the current week and report to begin with data from the current week.
So I have tried to use the variable :WEEK_OF_DATE (Item name) as the beginning date for the report. However :WEEK_OF_DATE is null.
Also, after I have the report displayed, I would like to select a new date from the list and have the report automatically refresh with that new data.
Any Ideas what I am doing wrong?

Hi Lyle,
When setting a default value for a select list that is to be used to filter a report, I have found it best to do that using a computation, conditional on the item being NULL and running Before Header. If other computations rely on this value, then it should have the lowest sequence number to ensure that the value is available for those.

$x_Hide/Show/Toggle works on a button, how about select list or tabs

** After looking at the issue for days I think everyone must know what I am trying to do and a Carl pointed out they don't so here is the Readers Digest Condensed version.
I want have a single page that displays or hides regions depending on what the user want to do. So there is a single region that provides summary data and multiple regions for updates or reports that only show when that option is selected. I have got it working with buttons, thanks to Carl for his examples and numerous posts.
Now the powers that be see that as too much clutter on the screen and want a select list for the options, as there may be 10 or 12 options on a single "page." Hopefully this clarifies what I am trying to do.
I don't see anyway for it to work on tabs, at least not the tab sets in ApEx but select list have a "Display As" option for "Select List Returning URL redirect."
This sounds like the button "Optional URL Redirect" property. I have the code working on buttons on the same page so I added a select list and tried it.
The #REGION_STATIC_ID# is set up on the template of the region type being used and the regions hide and show as expected with the buttons.
So I set up an item on the page as a "Select List Returning URL redirect"
I created a static select list as:
STATIC2:Option1;javascript:$x_Hide('REGION1');$x_Hide('REGION2');$x_Show('REGION3')
I tried it with single quotes around the returning URL, and got
mod_plsql: /pls/htmldb/'javascript:$x_Hide('COBORROWER');$x_Hide('PROPERTY');$x_Show('BORROWER')' HTTP-400 Name "'javascript:$x_Hide('COBORROWER');$x_Hide('PROPERTY');$x_Show('BORROWER')'" is longer than 30 chars
without single quotes and got
New, blank screen with REGION3
mod_plsql: /pls/htmldb/'javascript:$x_Hide('REGION1');$x_Hide('REGION2');$x_Show('REGION3')' HTTP-400 Name "'javascript:$x_Hide('REGION1');$x_Hide('REGION2');$x_Show('REGION3')'" is longer than 30 chars
I took out the java stuff and put www.yahoo.com and got
Not Found
The requested URL /pls/htmldb/WWW.YAHOO.COM was not found on this server.
So the URL is being appended to the /pls/htmldb...
Hmm... I also removed "javascript:" and tried with and without single quotes... no luck... still appending the returning URL to /pls/htmldb/.
Tabs would be best but a drop down list is cleaner than 8 buttons.
Ideas? Spare change?
I may need it :)

What a difference a day and a pointer make.
I created a test function in the page html header
<script type="text/javascript">
function test(){
window.alert('Function test');
</script>
Changed the static list to
static2:Option1;javascript:test(),Option2;javascript:test()
and the function worked. I then changed the function to
<script type="text/javascript">
function test(){
$x_Toggle('REGION1');
</script>
and the region toggled on and off.
I then changed the select list to
static2:Option1;javascript:test(),Option2;javascript:$x_Toggle('REGION2')
and region1 toggled while Option 2 produced a blank browser page with the "REGION2" in the upper left hand corner.
I made functions for Option1, 2 and 3 with the appropriate $x_Hide/Show for each region and the select list now acts like the buttons.
Thanks for the help. I guess the call has an issue with the functions that are not on the page or ???. Maybe Carl can help, but since I needed more complex functions anyway this does not represent any more work while allowing me the option of a single page with multiple forms and reducing the complexity of the UI.
Score...

"Auto-Submit" using select lists

hi, i have a few select list boxes that display data on a form, is there a way where i can have it "auto_submit" just by clicking an item on the list, instead of having a button with a branch to the same page?
Thanks,

Daniel,
Edit the select list item and in the "Display As" field, select "Select List with Submit"

AJAX dependent Select lists

Can anyone please help me figure out where am going wrong?
I have 2 regions on page 1. Region 1 is supposed to have 2 drop down lists (cascading i.e values in second drop down Drop List HJ are dependent on value selected in first lov Ajax Select HJ). Region 2 will be a report.
I am trying to create AJAX cascading lovs based on eg. provided on carl's application so that Region 2 is not refreshed each time I select a value from the drop down's
[http://apex.oracle.com/pls/apex/f?p=36391:37:1510004986327720::NO:RP::]
I have downloaded the application and tried to do the exact same steps, but my child lov is not updating its values after I select a value from in Ajax Select HJ.
My application is available at http://apex.oracle.com/pls/apex/f?p=33829:1:2010637670427735:::::
Appreciate any help on this
Thank you
Deepu

Thank you Denes !! The example really helped me. Now I am stuck at the next level. I am new to apex and learning and building dashboard for my organization. So, please bear with me.
I have a page that is divided into 4 regions. Each region displays a chart that is generated dynamically. When I say dynamic, each region has 2 drop down lists.
First pull down has Org and Year as values, if they wish to view chart by Org or Year. If they choose Org, second drop down defaults to Org. If they choose Year, second drop down displays Year's as 2010, 2009,2008 so on. Depending on which year they choose they should be able to view that Year's chart by month in that region.
Initially I had used select lists with submit for drop down's but that was refreshing the whole page. But now after using your example with AJAX I was able to accomplish the cascading Lov's stuff. Now, after user selects a value in second drop down, is there a way that I can display the chart and refresh only that region each time user selects a value from the drop down.
I want to avoid refreshing the page each time, I need each region to refresh based on user selection in drop down's. Is this possible in apex? Is there any example that you could direct me to.
Thank you so much for all your inputs. Appreciate it very much
Deepu

AJAX Dynamic Select List

Hello Ladies and Gentlemen,
I have a Select List, :P9_ELEMSTRUCTSAISIEPARCBO, based on a hidden item, :P9_NOSAISIEPAR, and this is the query it's based upon:
select Description, ElemStructID
from V_ElemStruct, V_Dispensateur
where DispensateurID = DispensateurIDResponsable
and NumeroDispensateur = :P9_NOSAISIEPAR
order by DescriptionI also have a popup page that shows a report with a column link that passes back values to the original page, and one of those values replace :P9_NOSAISIEPAR's current value. I want to reload the Select List via AJAX, so that the changes can be in real-time. I found Carl Backstrom's (He was a wonderful man) tutorial on his application (http://apex.oracle.com/pls/otn/f?p=11933:37) and decided to try it. But it just won't work, and I have no idea why.
I know the popup works just fine, and I tested the On Demand Application Process in the SQL Commands of the SQL Workshop and it seems to be working just as fine. Thus, I've narrowed it down to the thought that the JavaScript must be the problem, logically.
Here is the code for the "HTML Form Element Attributes" of the :P9_NOSAISIEPAR hidden item:
onChange="f_PopulateField(this,'P9_ELEMSTRUCTSAISIEPARCBO')"Here's my on Demand Application Process:
begin
owa_util.mime_header('text/xml', FALSE);
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
htp.prn('<select>');
for rec in
(select
     Description as Description,
     ElemStructID as ElemStructID
   from
     V_ElemStruct,
     V_Dispensateur
   where
     DispensateurID = DispensateurIDResponsable
     and NumeroDispensateur = :F102_TEMP_APP_ITEM
   order by
     Description
) loop
htp.prn('<option value="' || rec.ElemStructID || '">' || rec.Description || '</option>');
end loop;
htp.prn('</select>');
end;and here's my JavaScript:
function f_PopulateField(pThis,pSelect)
var l_Select = $x(pSelect);
var l_Return = null;
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=PopulateField',0);
get.add('F102_TEMP_APP_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);
I have installed FireFox and FireBug, and I tried to debug my JavaScript, and that made me realize something. In the FireBug's HTML tab, :P9_NOSAISIEPAR doesn't have any onChange events mapped to it (and all my other items which should have an event mapped to them do have one).
<input type="hidden" id="P9_NOSAISIEPAR" value="2222" name="p_t63">compared to:
<select onchange="$f_Show_On_Value_Item('P9_SECURITAIRE','P9_NOTEACCOMPAGNATEUR',1)" id="P9_SECURITAIRE" size="1" name="p_t23">So, my best bet is that the JavaScript doesn't even get executed by the page at all (it's not appearing in FireBug's JavaScript tab at all either). Any idea why?
Best regards,
Mathieu

I finally found a way to do it. When selecting my value in my popup page, I show my hidden field, change the value, manually call the onChange event, hide back my hidden field, and then close the popup. That way the onChange event fires in IE. Afterwards, as a workaround to the XML not being recognized by IE, I changed
get.get('XML')for
get.get()to get a string instead of some XML, and I parsed it to XML DOM using a manual parser (because IE is too weak to have its own). Here is the code for the DOMParser.
if (typeof DOMParser == "undefined")
    DOMParser = function () {}
    DOMParser.prototype.parseFromString = function (str, contentType)
      if (typeof ActiveXObject != "undefined")
        var d = new ActiveXObject("MSXML.DomDocument");
        d.loadXML(str);
        return d;
      else if (typeof XMLHttpRequest != "undefined")
        var req = new XMLHttpRequest;
        req.open("GET", "data:" + (contentType || "application/xml") +
                         ";charset=utf-8," + encodeURIComponent(str), false);
        if (req.overrideMimeType)
          req.overrideMimeType(contentType);
        req.send(null);
        return req.responseXML;
}It wasn't written by me, I found it on Erik's Weblog (http://erik.eae.net/archives/2005/07/03/20.19.18/), so all credit goes to him.
Best regards,
Mathieu

Using a Select list with Submit

I am trying to use the select list with Submit on my page.
I have 3 select lists.
On the first one,I am showing the list of all jacks.
When the user selects a jack from the first list, I want to show all the jacks except the one which was selected.
When the user selects a jack from the second list, I want to show all the jacks except the ones selected in the first list and the second list.
I have created the select lists with submit and then I have put the query for getting the jacks. I created an unconditional branch. I am also passing the variables so that I can set the values of the items on submit.
I also created a computation as mentioned in one of the OTN discussions, and have mentioned the value of second list to be calculated from the first and 3rd from first and second.
But after clicking the first select list, I am losing all the existing values on the first page. I wonder what I am missing here. Can anyone hellp?
Thanks,
Gargi

Gargi,
In this case using 'select list with redirect' makes more sense rather than with SUBMIT. So change all the select lists to 'select list with redirect' (it redirects to same page inserting 'select list' value session state).
Now for the 2nd select list query add a condition in where clause like
WHERE sl_col != :P1_SL1And for the 3rd select list query add a condition in where clause like
WHERE sl_col NOT IN (:P1_SL1, :P1_SL2)Hope it helps :-)
Cheers,
Hari

Select list within interactive report.

Hello y'all,
I have a need to develop an interactive report and am lost in how to proceed. I am asking for your help. The report requirements are as such:
- There are 3 types of records that will be in the report
- The is a checkbox to associate the records to a particular event.
- If the record is of a certain value, 3 of the columns in that record have to show as select lists.
- The records with the other 2 values should not have the select lists, just show a null in those columns.
- The checkbox must be checked for the select lists to appear.
- The select lists are based on a list of values. The values are populated with an existing common function used in many of the application pages.
I am having no success in trying to get the select lists in the report. Has anyone developed an interactive report that uses select lists within the report? Is this even possible?
I am using application Express 3.2.0.00.27. Any help that you can give is greatly appreciated. Thank you so much!
*** Got it. It has to be a tabular report with updateable columns. ***

Hi,
I am not sure if the "equal to" condition applies to a DOM object... after all, a DOM object can be anything (any HTML element) not only a field.
Try using a javascript expression instead, like this:
$v('P6_IR_SELECT_LIST')=='Delete'UPDATE: Sorry, I just tested and "equal to" condition works for DOM objects... should have tested before posting!

Select List with the current value

Hi,
I have a Page suppose Page1 with 2 region.
Region1 is having SEARCH button (target page 1 itself) and a SELECT LIST called Deptno (10,20,30,40)
Region2 is just a simple employee report based on Deptno (where deptno = :p1_deptno)
Now when I suppose select deptno 30 and press SEARCH button, report is not displayed and also Dept select list current value becomes the first one in the list i.e 10.
My question is after submitting the same page 1 using SEARCH button, how can I display the selected value (dept 30) in the select list.
Note:- If I am using Select List with Submit then it's working fine and also displaying the current value (30) in the list, But I am looking for using SEARCH button.
Thanks,
Deepak
Edited by: Deepak_J on Aug 6, 2009 2:14 PM

Hi,
Then the value that is selected in the list will not be submitted, so it will not be saved. You need a button that submits the page.
