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

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.

Newbie: how to create a dynamic select list of the current date + 5 years

Hi - I'm a JSP newbie (coming from a PHP background), and am trying to create a select list that contains the current year, plus 5 years. So, the list when generated (today), would display:
2007
2008
2009
2010
2011
2012
Obviously, the code would need to generate inside the option tags, as well as in the value property of the option tag.

function addit(){
          var val = 2012; //you can take this from js date object and strip it off
          for (var i=2007; i <= val;++i){
               addOption(document.getElementById("mycombo"), i, i);
function addOption(selectbox,text,value)
     var optn = document.createElement("OPTION");
     optn.text = text;
     optn.value = value;
     selectbox.options.add(optn);
}without hardcoding:
function addit(){
          var dd = new Date();
          var yearnow = dd.getFullYear();
          for (var i=yearnow; i <= yearnow + 5 ;++i){
               addOption(document.getElementById("mycombo"), i, i);
function addOption(selectbox,text,value)
     var optn = document.createElement("OPTION");
     optn.text = text;
     optn.value = value;
     selectbox.options.add(optn);
in your jsp:
<body onload="addit();">
<form>
<select name="mycombo">
<option> Select year</option>
</select>
</form>
</body>

Update select list with dynamic LOV

How exactly do you do this?
Currently I have a text field which the user may enter a product type and a button when click. It would populate the select list with the product names that associate with that product type...
My lov would retrieve the product type value text field(:P1_t_prod_type) and get products names by type
select t_prod_name A , t_prod_name B
from t_prod_items
where t_prod_type = :P1_t_prod_type
order by 1Im kind of stump on is setting up my dynamic action to "set value" to the select list. As nothing seems to be appearing.

product type is a numeric value that can be a wide numeric range. (I don't know why the column is named like that. Sorry for forgetting to mention that)
Well I don't think i should submit the page? because after the list box is filled with product names. the user can then select one of those names from the list box and continue completing the rest of the form. After all that the page would then be submited. (Well that's how i imagine it to work...)
Wouldn't i run into problems if i were to submit the page twice... like lost entry in other text fields if the user were to skip that part at the start.

Select list with bind variable does not work

Hi,
What can be wrong with a 'select list' with the a simple select
select omschrijving o, id i
from basiscodes b
where domein = 'OPTIES'
and b.id in
(select eo.basiscode_id from evenementen_opties eo
where eo.event_id = :P16_ID)
The :P16_ID has a value and should give result
But it does not work at all with 'select list'
Using the POPUP LOV (display discription, return key value) works nice
The select retuns less then 10 records

Hi Flavio,
As I explained, the P16_ID is an item of the master page (page 16)
In Page 18 where I want to reuse that value, the item is not there, but I use it to assign
P18_EVENT_ID with the value in P16_ID and that works fine.
In an after submit process, I do this :
declare
function get_pk return varchar2
is
begin
for c1 in (select EVENEMENT_INSCHRIJVING_SEQ.nextval next_val
from dual)
loop
return c1.next_val;
end loop;
end;
begin
:P18_ID := get_pk;
:P18_EVENT_ID := :P16_ID;
:P18_CREATIE_DT := TO_CHAR(SYSDATE,'DD-MM-YYYY HH24:MI:SS');
:P18_CREATIE_USER := APEX_APPLICATION.G_USER;
end;
The value P16_ID is there before I open page 18
I made a display item that displays the value P16_ID
If I change the LOV select in :
select b.omschrijving o, b.id i
from basiscodes b
, evenementen_opties eo
where b.domein = 'OPTIES'
and b.id = eo.basiscode_id
and eo.event_id = 16
then it returns the value I want : 1 record
You see, I'm a really new one in apex.
Forms 6i was easier for me...

Creating Select List with multiple columns

I want to create a select list with multiple columns. I followed the demo application model described in the by Denes Kubicek (Currently my reference for APEX !!)
The code is as follows:
CREATE OR REPLACE FUNCTION getcrops(p_cropid IN NUMBER)
RETURN VARCHAR2
IS
v_cropid VARCHAR2 (400);
v_fcode VARCHAR2 (400);
v_product VARCHAR2 (400);
v_var VARCHAR2 (400);
v_fname VARCHAR2 (400);
v_acres VARCHAR2 (400);
v_style_start VARCHAR2 (400);
v_style_end VARCHAR2 (400);
v_return VARCHAR2 (400);
BEGIN
FOR c IN (select "CROP"."CROPID" as "CROP ID",
     "CROP"."FIELDCODE" as "FIELD CODE",
     "CARROTPRODUCTLIST"."CARROTPRODUCTNAME" as "PRODUCT",
     "VARIETYLIST"."VARIETYNAME" as "VARIETY",
     "FIELD"."FIELDNAME" as "FIELD NAME",
     "CROP"."SIZEINACRES" as "ACRES"
from     "FIELD" "FIELD",
     "CARROTPRODUCTLIST" "CARROTPRODUCTLIST",
     "VARIETYLIST" "VARIETYLIST",
     "CROP" "CROP"
where "CROP"."CARROTPRODUCTTYPE"="CARROTPRODUCTLIST"."CARROTPRODUCTID"
and     "CROP"."VARIETYID"="VARIETYLIST"."VARIETYLISTID"
and     "CROP"."FIELDID"="FIELD"."FIELDID")
LOOP
v_cropid := TO_CHAR (c.'CROP ID', 'FML999G999G999G999G990');
v_fcode := c.'FIELD CODE';
v_product := c.'PRODUCT';
v_var := c.'VARIETY';

END;
I created this anonymous Pl/SQL function at a application level ..Then I followed up to create a select list with a function inside. However I could not create select list with the command suggested in the demo which is
select getcrops(cropid) d, cropid r from crop;
APEX (2.1) returns a error message. What am I missing ? Should the function be called from somewhere else after creating a regular select list..? Where the functions (Pl/SQL) should be ideally stored for application level access..? and for across application level access ? How can I check the function works good. Help is appreciated.

Still really one column.
If they need to be independent then you've got to have three selection lists.

Dynamic select list with display,return val & join condition issue.

hello,
I am having a dynamic select list with display, return value
say for example my select statement is
select distinct dname d, deptno r
from dept dt
right join emp e on (e.deptno=dt.deptno)
where (condition)
when i tried this query for my select list, it is not working. It saying that
" 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. "
I am not able to understand the problem. Can anyone help me out with this issue?
thanks.

Shouldn't your join have dept as the driving table?
select distinct dname d, deptno r
from dept dt
right join emp e on (dt.deptno = e.deptno)
where (condition)
Or using older Oracle standard join
select distinct dname d, deptno r
from dept dt, emp e
where (dt.deptno (+) = e.deptno) AND (OTHER WHERE condition)
OR
(Since a right join is just getting the values from the driving table that are NOT in the associated table)
select distinct dname d, deptno r
from dept dt
WHERE dt deptno NOT IN (SELECT deptno FROM emp) AND (OTHER where condition)

Dynamic select list with displaying a description

Hi,
I want to have a select List, my list refer to a lov, and the lov refer to a table contaning 2 columns : code and description,
The list must display only the code, but I want having an item beside the list dispaling the description....
I have used a select list with the query :
select code d, code r from prog_theme order by 1 desc
and Now : what is the way for displaying the description
Thanks!!
Lila

Ok, here goes the top down approach...
In the HTML header of my page, i have this reference to a js file containing the javascript - <script src="#WORKSPACE_IMAGES#108.js" type="text/javascript"></script>
Then in an HTML Region I have the following code to create the divs that will be shown and hidden - <div id="divREGION" class="divs">Select region to get list of countries.</div>
<div id="divCOUNTRY" class="divs">Select country to get list of cities.</div>
<div id="divCITY" class="divs">Select city and then press "Get Employees". </div>
Note that these divs contain static content. You may be able to create dynamic content for these divs by creating dynamic query regions and putting div tags around the region (i havent tried this, it may require template modification).
The select boxes have this code in the "HTML form elements attributes" - onFocus="javascript:showHideDiv(this,true)" onBlur="javascript:showHideDiv(this,false)"
This onFocus and onBlur call the showHideDiv() function, passing in the object reference of the select box and a true/false to show/hide the related div.
The actual javascript function that is contained in the 108.js file is:
function showHideDiv(objThis, inBool){
     var divid = "div" + objThis.id.substring(3);
     if (inBool) {
     ShowDiv(divid);
     else {
HideDiv(divid);
That function in turn calls either the ShowDiv() or HideDiv() functions, depending on the true or false, passing in the ID of the div to be changed...
function ShowDiv(divid){
     eval('document.all'+ '["' + divid + '"]' + '.style' +'.display = "inline"');
function HideDiv(divid){
     eval('document.all'+ '["' + divid + '"]' + '.style' +'.display = "none"');
Hope this helps.

Hello Larry,
You can use a select list with submit and create a branch to the page you want to go to.
Hope that helps.

Select list with URL redirect - not showing the same display value selected

Hi
I have several select lists with URL direct on my page similar to this
for p6_queries item the LOV is
select QUERY_NAME display_value, 'f?p='
|| :APP_ID
|| ':'
|| 6
|| ':'
|| :APP_SESSION
|| '::::p6_queries:'||QUERY_ID||'#qtables' return_value from .....
I am assigning a return value to the item p6_queries. But when the page is redirected, I dont see the selected value as selected in the list. Instead it goes to the null display text. Can any one help me on this?

The problem is that your setting the item value to value of query_id. But your select list has the value of each item as the URL so it will never match and show you what you selected.
The best thing to do may be to change your select list from a "redirect to URL" to "submit page", make it a normal query:
select QUERY_NAME display_value, QUERY_ID return_value ...
Then create an "On Submit: Before Computation" branch:
Target Type: URL
URL Target: f?p=&APP_ID.:6:&SESSION.::&DEBUG.::P6_QUERIES:&P6_QUERIES.#testing
Condition Type: Request = Expression 1
Expression 1: P6_QUERIES

How to display the current value selected in DDLB of another screen

hi Experts
I need some info regarding the dropdownlist in BSP.
I have two screens . One screen contains the table view which contains a set of records.Each record has two columns.
Second screen contains 2 drop down list.
When i select one record and then press the submit button in the first screen .Then i want that the selected value of the selected record will display in the DDLB of the second screen. And then i can again select the value from the drop down list.
For example:
1st screen:
record 1.
col 1     col 2
record 2
col 1     col 2
2nd screen
ddlb1...........
ddlb2...........
So when i select the record1, then the current value of col1 and col2 should visible on the ddlbs of second screen first time. Then i choose other value from the ddlbs.....
My Question is how to do the following
"when i select the record1, then the current value of col1 and col2 should visible on the ddlbs of second screen".
please provide some suggestions...
Thanks.

Hi,
You can use form with post method
like
<htmlb:form method = "post"
                  action = "page2.htm"
                  target = "coding" >
<htmlb:dropdownListBox id             = "labelAlignment"
                                           selection      = "<%= me->labelAlignment %>"
                                           onClientSelect = "document.forms[0].submit();" >
                      <htmlb:listBoxItem key   = "LEFT"
                                         value = "LEFT" />
                      <htmlb:listBoxItem key   = "RIGHT"
                                         value = "RIGHT" />
                    </htmlb:dropdownListBox>
So once you select col1 and col2 in your case its value is in page attribute say hold, this attributes needs to be defined in page2.htm also with auto checked. You can get the val selected in page1.htm
If helpful rewards point.

Albert

Item(select list) with LOV and Report with link = changed value item

Hello,
On one page I have:
- Item 'P_name' (select list) with LOV to select name of a person;
- Items 'factory' and Report 'factory'(standard created with 'Form with Report' on the same page).
Situation:
All works fine. I selected first a LOV Item 'P_name' (say 'Jane'). But....
Only when I select a record (to change the values) from the report 'factory' then LOV Item 'P_name' become empty. Report used a link to the same page to fill the report items 'factory' and make also the LOV item empty.
Question:
I have made a process that write the name 'Jane' to table.
I see two possibilities:
- LOV Item value => fill the LOV item with 'Jane' from the table before region. Is this possible?
- Report => What is the buttonname of reportlink? I can use this name in the processes.
Thanks Walter!

1) what i meant was for you to test this ridiculously huge LOV outside of htmldb, but it occurred to me last night that you could, in fact, be hitting a limit of ours. after some poking around, i have confirmed that. select list items in htmldb are currently limited to 10,000 rows. this was initially done for performance reasons, but they're now opening up the restriction. if you really need to work with that many rows where the user is allowed to pick from a set of values, consider using a popup item type instead. it'd help your app performance as well (in my test cases, it stank to have to wait for my 10k select list rows to come down to my browser).
2) sorry to not have been more clear about this, but when you set your item's "Source Type" back to "Database Column", you'd have to specify that column in the "Source or value expression" field. also, you can't put a sql query into that "Post Calculation Computation" field. as i said before, "you can take a look at the attribute-level help for that field to see implementation examples."
3) stick with "Always..." for now if you're using our auto-dml process(es)

Select list with redirect and save the item to insert row

On the Form, I want to select from the item (P105_ADMIN_DOMAIN_ID)
and pop the result on the item (P105_ADMIN_NAME).
P105_ADMIN_DOMAIN_ID define:
Display as "select list with redirect"
Alternate source used "Only when .."
Source Type "Database Column"
Source Value or express "ADMIN_DOMAIN_ID"
P105_ADMIN_NAME define:
Display as "Text Field"
Altrenate source used "Only when .."
Source Type "SQL Query"
Source Value or express "select party
from responsible_party
where logonid
= :P105_ADMIN_DOMAIN_ID"
questions:
1. item P105_ADMIN_DOMAIN_ID DROP DOWN LIST is limited to
some threadhold, it did not list all the value from
the LOV which is follow:
select LOGONID d, LOGONID r
from RESPONSIBLE_PARTY
order by 1
2. I want to insert a row after complete the form.
But my item P105_ADMIN_NAME is defined
Source Type "SQL Query" instead of the 'Database
Column'
How could I overcome these?
Thanks so much for your help.

Can we have the 'select list with submit' type within a tabular form?

An item can be the "Select list with submit' type so a form has no problem with it. However, when I built a tabular form manually, I couldn't find this type. There are only three types avaiable: "named", "static", and "dynamic".
Is it possible to have the "submit" type so columns of the tabular form can be dynamically rendered based on the user inputs?
Another question I have is how to dynamically build the tabular form with decode func. For example, if the value of col_1 is 'val_1', then build a select list in col_2; otherwise null in col_2.
I tried to use
select col1,
decode (col1, 'val_1', select htmldb_item.select_list_from_lov(2, first, 'lov1') from dual, null)
from....
where....
But it didn't work.
I'd like to know whether it's feasible to have something like that.
TIA.

You could use a region of type PL/SQL function
returning SQL query to dynamically build this kind of
tabular form. However if you want to use the built-in
multi-row insert, update and delete processes, all
items in a column must have the same display type. Marc, thanks for the quick reply. I appreciate it.
I got your idea. However, I need to have the javascript 'ToggleAll' as the heading so the form works as same as the built-in one. If I put the query definition into a pl/sql procedure, where I can put this html tab attribute? It can not be inside the checkbox function, otherwise the checkbox of any row would act as same as the header.
I hope I've made this clear.
To Vikas: It's our clients who want this, not us. :(

Compare the current value with the previous value in the same column

Hi all,
I have to include a statement in a query which allows to compare the current value of column A with the previous value of column A (same column). from there, I need to add a condition in order to have the expected result.
Let's take an example to illustrate what I want to achieve:
I have the following columns in table called 'Charges':
Ship_id batch_nr Order_nr Price
SID1111 9997 MD5551 50
SID1111 9998 MD5552 50
SID1111 9999 MD5553 50
SID2222 8887 MD6661 80
SID2222 8887 MD6662 80
SID2222 8887 MD6662 80
SID3333 6666 MD7771 90
I want to check if the ship_id of row 2,3 (and more if available) is equal to the ship_id of row 1.
If it is the case, then value 'together with the first batch_nr' in row 2 and 3 under Price column. If not, then keep the original value of Price column
PLease see below the expected result:
Ship_id batch_nr Order_nr Price
SID1111 9997 MD5551 50
SID1111 9998 MD5552 together with 9997
SID1111 9999 MD5553 together with 9997
SID2222 8887 MD6661 80
SID2222 8887 MD6662 together with 8887
SID2222 8887 MD6663 together with 8887
SID3333 6666 MD7771 90
Thanks in advance for your help, it is really urgent.

]That looks like the query you were using before you started this thread.
Modify it, using the analytic fucntions FIRST_VALUE and LAG, like I showed you.
I see that you did simplify the problem quite a bit, and it's good that you did that.
It doesn't matter that your real problem involves joins or GROUP BY. Analytic functions are calculated on the results after all joins and GROUPS BYs are done. Just substitute your real expressions for the simplified ones.
For example, in your simplified problem, there was a column called order_nr, but I see now that's it's really called o.ordnum. Where the solution I posted earlier says "ORDER BY order_nr", you should say "ORDER BY o.ordnum".
Here's a less obvious example: in your simplifed problem, there was a column called price, but I see now that it's really SUM (tc1.chrg_amt + tc2.chrg_amt + tc3.chrg_amt). Where the solution I posted earlier says "TO_CHAR (price)", you should say "TO_CHAR (SUM (tc1.chrg_amt + tc2.chrg_amt + tc3.chrg_amt))". (You can't use an alias, like "Total Price", in the same SELECT clasue where it is defined.)
I removed some columns from the select as they are not relevant for the wanted action like 'adress details or other references'.
Now here is the result:
Shipment ID     Order Number     WMS Batch     Freight      Fuel Price Order Total Price
SID0132408     MDK-000014-05602649     04641401     110     10 120
SID0132408     MDK-000014-05602651     04641402     110     10 120
SID0132408     MDK-000014-05602652     04641363     110     10 120
as you can see, the 3 orders have the same shipment ID.
The expected result should be shown under column 'Total Price' as follows:
Shipment ID     Order Number     WMS Batch     Freight      Fuel Price Order Total Price

But where is the raw data that you're starting with?
It looks like you tried to format the code (but not the results) by typing this 1 character:
before the formatted section and this different character
after the formatted section. To post formatted text on this site, type these 6 characters
before the formatted section, and the exact same 6 characters again after the formatted section.

How to compare, current value in :block.text_item with the database value

Hi
Could you please tell me
How to compare the current value in :block.text_item with the corresponding database column value.
I am using forms 10g
There is block and there is an text Item in that block.
When I run the form and query the block (tabular), the :block.text_item shows me, whatever value there in the database.
Now I add some value in the :block.text_item to the existing value.
now
the :block.text_item contains old+ new added value
whereas
the database table contains 'old' value
Now on a button click , I want to find out what is the value that I have added
Could you please tell me, is it possible without writing a select query?

Hello,
Now on a button click , I want to find out what is the value that I have addedSo you mean always user will add value in the existing value. Because this way will fail in one case. Let say
Value in Database is = ABCD
User opened the form and he removed the D and write E and now value is ABCE and length is still same 4. So, there is no addition.
Anyway you can know the database value at runtime there is one property for item called DATABASE_VALUE. It gives the value which is in database while you are running the form before save. and you can use like this..
Trigger = WHEN-MOUSE-DOUBLE-CLICK on item level
DECLARE
vItemValue DATATYPE; -- Set the data type according to your desired field.
vValueAdded DATATYPE; -- Set the data type according to your desired field.
BEGIN
vItemValue:=GET_ITEM_PROPERTY('ITEM_NAME',DATABASE_VALUE); -- It will return you the database value in vItemValue variable.
IF LENGTH(vItemValue)>LENGTH(:FORM_ITEM_NAME) THEN -- It mean something change or added
vValueAdded:=SUBSTR(:FORM_ITEM_NAME,LENGTH(vItemValue)+1);
MESSAGE('Added value is : '||vValueAdded); -- It will show you the added value.
END IF;
-- now suppose you want to show the old and new value in message not the added one
-- Then no need of IF condition. You can just use message like this
-- And i would prefer to use like this way
MESSAGE('Old Value : '||vItemValue||' New Value - '||:FORM_ITEM_NAME);
MESSAGE('Old Value : '||vItemValue||' New Value - '||:FORM_ITEM_NAME);
END;Hope it is clear.
