HTMLDB_ITEM.CHECKBOX

I used HTMLDB_ITEM.CHECKBOX(1,"field") in a tabular report, now I need to make a button, or something like that, to select all the row checkboxes, but I don't know how to work with it, I'd really appreciate if anyone could help me with this, giving me the link to any page about it or telling me the way to do it.

Change Value of HTMLDB_ITEM using HTMLDB_ITEM.CHECKbox

Hello,
I've got a region with a 'pl/sql function returning sql query'
declare
q varchar2(4000);
begin
q:=' select htmldb_item.checkbox(1,t.jedi_ean_id) as Auswahl, ';
q:=q||' t.ean, j.artikelbezeichnung, ';
q:=q||' t.artikelmengeneinheit, ';
q:=q||' htmldb_item.text(2,t.iln) as ILN, ';
q:=q||' from malus.jedi_ean t; ';
return q;
end;
My Query return for example 10 rows. Now I want to check 5 of this 10 rows using the checkbox.
With the following PROCESS i am able to save the new values of the field ILN to the Database.
for i in 1..HTMLDB_APPLICATION.G_F01.COUNT
loop
update jedi_ean j
set j.iln = HTMLDB_APPLICATION.G_F02(i),
where j.jedi_ean_id = HTMLDB_APPLICATION.G_F01(i);
end loop;
Now to my Problem:
I want to have an input field outside of this report where the user can manually set the value of the field ILN.
Afterwards the user checks 5 of the 10 rows and then he should have the possibility to click on a button
to assign these values to the 5 checked rows in the report, not in the database.
After this step the user should click on a submit button an start the existing process above.
Is this possible??

Hi,
I do not know can you do that with dynamic action or is there of of box solution.
But see this example
https://apex.oracle.com/pls/apex/f?p=40323:30
You can bind onchange event to text field, and call Ajax to get emp name.
Then use sample JavaScript to set value to display only item

HTMLDB_ITEM.CHECKBOX and Multiple Pages

Hi
I have used a SQL query as a source for a region and I generate checkboxes dynamically using HTMLDB_ITEM.CHECKBOX function. Everytthing works fine as long its in one page. When I set the pagination to show only 15 rows per page and when I click save from the second page (showing rows 16-30) the value of HTMLDB_APPLICATION.G_F01.COUNT becomes zero. And the values of the checkboxes are not recognised. Is this a known issue and any solutuion to it?

Hi,
two part question:
Do I need to pass session state from page to page in the same application? (I do not think so, but I am not sure)
secondly do you know why this code
for i in 1..htmldb_application.g_f01.count
loop
if htmldb_application.g_f01(i) !=0 then
:P14_INFO_ID := htmldb_application.g_f25(htmldb_application.g_f01(i));
end if;
end loop;
in which I am trying to get 1 column for the row that is checked
would result in this in the debugger:
...P14_INFO_ID session state saving same value: "" indicating that the session state for that column was not saved?

Hi Tyler,
Here is the example:
Table 1.
Issues Table:
issue id, issue_Description
Projects:
project id, Description
Project_issues:
project id, issue id, issue encountered(Y/N)
I want to display read only checkboxes.
issues decription is stored in Issues Table, and values (Y/N) are stored in Project_issues
So for a particular project I would like to see list of all issues(checkboxes)
This is how it looks like
For projectid: p1

This lov display checkboxes. But How Can i get values of these checkboxes from table project _issues.
thanks a lot for your help

Label for htmldb_item.checkbox

Is there a way to put a display label for checkboxes rendered with htmldb_item.checkbox?
I know it doesnt make much sense to put a label on every row next to each checkbox on a report region, but just wanted to know if it was possible.
Thanks

Thanks, that works!
I just tested this out on the hosted site (24317:4)
What does the
onMouseOver="row_mouse_over1517788416209474431(this, 1)"
stuff in the table do? I am pretty sure I dont get that on my site. Is it related to the theme/template? it doesnt seem to do anything
Thanks

HTMLDB_ITEM.CHECKBOX p_checked_values Length 4000

Hi,
I am using the HTMLDB_ITEM.CHECKBOX and the values that are checked by default is dynamically generated. Once the length of p_checked values crosses 4000, I get the following error.
ORA-01704: string literal too long
Please suggest if there is a workaround for the same.
Thanks,
Rajesh.

I am trying to generate a report. This is how the query is returned.
q := ' select HTMLDB_ITEM.CHECKBOX(1,empid ,NULL,'
|| ''''
|| v_existing_selection
|| ''''
|| ','
|| ''':'''
|| ')'
|| '"Select",'
|| ' col2'
|| ' col3'
|| ' col4
|| 'from table 1,table2'
The v-existing selection which indictes the boxed to be checked by default is formed dynamically. It has the list of all the Ids that satisfy a particular criterion.
So, when the number of Ids are more, the v_existing_selection length increses adn at one point, it crosses 4000 and i get the error stated above.
Please advice.

A quick question about the htmldb_item.checkbox function

I know many posts about checkbox have been posted, yet I couldn't find the answer after some searches.
I have something like:
select
htmldb_item.checkbox(1, col_name)
from...
What I need is to have is the the heading of the checkbox column same as what the wizard does. I mean you can 'check all' with that. If I put a string after the right parentheses, I got that string rendered as the name of the checkbox column, which was not I want.
I couldn't find the answer from the document, neither from the how-to.
Thanks in advance.

If this is not what you want I don't understand exactly what it is that you're attempting. Perhaps some elucidation would be in order?

Checkboxes - htmldb_item.checkbox multi-record updatable report

htmldb_item.checkbox can be used to display retrieved database values as a check box (e.g. a Y/N Flag).
These can also be added to an updateable report in a multi-record tab.
When a new record is created on the multi-row tab however there appears to be no way to render a checkbox. Instead a text box appears instead.
Is there any way to acheive this?
This data needs to be present in a multi -row layout
Thanks
BTW - I have checked the docos and read the forums.

Firstly, thank you for the reply.
I must clarify what I am doing.
I have a table that has a column in it that is called ZEROFUEL. This can have a value of either Y or N. The user wants a block of these records (say eight) per screen. This column need to be represented by a checkbox. I manage this by calling the NVL(htmldb_item.checkbox(10,ID, DECODE (ZEROFUEL,'Y','CHECKED')),'N')ZEROFUEL, in the report select statement.
The automatic checkbox (for deletion) is added by the wizard no problem. It is the checkbox for the column ZEROFUEL I am having the problem with.
If I do not render the checkbox from the sql select then the wizard just creates a little text field display.
Everything works fine until I press the ADD button. A new record pops up on the bottom of the block with no checkbox on the ZEROFUEL column.
Eventually there are four columns I need to display as a checkbox. These all need to be displayed in the multi-record tab.
Am I missing something.
Thanks

Remember htmldb_item.checkbox selection after submit

i have a report that includes a checkbox column. i wish to submit the page(and return to same page) and at the same time remember the selections made by the user. is this possible?

is it not possible to treat the htmldb_item like this
No. See Re: Problem: cannot reference value of APEX_APPLICATION.G_Fxx
The arrays created by calls to htmldb_item are only to capture user-input for subsequent accept processing. You use the values during accept processing and when the page is re-displayed, unless you have the values stored in the database/collection and refer to them using the appropriate parameters to the htmldb_item API, the form elements (checkbox) will be blank.

Unable to get checkbox working in Apex 3.2.1.00.10

We recently upgraded our production application running on apex to Apex 3.2.1.00.10. Everything works, except for the query that generates the check-box. This used to do so in the previous version 3, but does not work anymore, the code is the same...Any help is appreciated.
(SELECT app_user, app_session, hier_username, NULL, NULL, NULL, NULL,

Not sure what happened, as I had tried this before too, but I did do the change below and was trying to debug the issue on my own and trying some options, and all of a sudden it started working...The only change that I did is below:

Issue with checkbox on tabular form

Hi (to all my friends in deperate times),
I have a tabular form on a page, which i use for addition of record only. So it always displays me a blank row, which is ready to be inserted after user has filled in data and clicked submit button.
Now I have a checkbox field on this tabular form. Since all the columns i show as null, I also show this checkbox as unchecked when page shows up. Here is the query for the source region of this form:
SELECT null "Client",
null "Currency",
HTMLDB_ITEM.CHECKBOX(40,'YES',null) critical_box,
FROM dual
I have used 'YES' as return value of this checkbox( when user has checked it, else i assume it will be not equal to 'YES').
I have my own update process, which gets fired on click of 'Submit'.
this is my insert clause in this update process:
INSERT INTO table1
(client, currency,critical_level)
values
(APEX_APPLICATION.g_f01(i), APEX_APPLICATION.g_f02(i), decode(APEX_APPLICATION.g_f40(i),'YES','YES','NO')
Now problem is that when i click checkbox and save it, it adds record correctly. But when i dont click checkbox during insertion, at that i get error message that no data found. It should insert 'NO' for 3rd column when checkbox is not clicked.
Please help here. Not sure why its giving no data found error when checkbox on tabular form is unchecked.
Thanks and Regards,
Rave.

Hi,
In the linked thread, the solution was to provide a second, hidden, item that always returned a known value. This item, also created using the APEX_ITEM package, uses the same index number as your checkboxes - so, if your checkboxes use index 40 (to get "f40"), then the hidden item uses 40 as well. This way, we always get at least one value for each row and the last possible value in a row will be known.
So, assume that the hidden item values are "NO", you have 10 rows on the page and the user ticks items 1, 2 and 5. The f40 items submitted would be:
YES:NO:YES:NO:NO:NO:YES:NO:NO:NO:NO:NO:NO
so, there will ALWAYS be 10 "NO" items and the YES item immediately before it will be the checkbox on the same row. So, if we loop through all f40 items, the YES values mean the checkbox and the NO values mean end-of-row - and, if we keep track of the NO values, we know which row we are on.
So, the code to find the data in f01 and f02 relating to the the YES values (the checked checkboxes) would be something like:
DECLARE
vROW NUMBER;
vF01VALUE VARCHAR2(100);
vF02VALUE VARCHAR2(100);
BEGIN
vROW := 1; // current row number
FOR x IN 1..APEX_APPLICATION.G_F40.COUNT
LOOP
IF APEX_APPLICATION.G_F40(x) = 'NO' THEN
   vROW := vROW + 1; // end of the row, so move to next row
ELSE
   // found a checkbox, so get related data
   vF01VALUE := APEX_APPLICATION.G_F01(vROW); // f01 item on the same row as the checked item
   vF02VALUE := APEX_APPLICATION.G_F02(vROW); // f02 item on the same row as the checked item
END IF;
END LOOP;
END;Andy

Checkbox in report

I am trying to duplicate (somewhat) some an idea presented by Denes
http://htmldb.oracle.com/pls/otn/f?p=31517:123
in his excellent example, but I cannot seem to get a handle on his update process is doing:
See some of my confusing comments inline:
-------------code starts
DECLARE
vrownumber BINARY_INTEGER;
vfound BOOLEAN;
BEGIN
-- update new checkboxes
FOR ii IN 1 .. HTMLDB_APPLICATION.g_f07.COUNT -- your checkbox
LOOP
vrownumber := HTMLDB_APPLICATION.g_f07 (ii);
-- only if checkbox hasn't been checked before
IF NVL(HTMLDB_APPLICATION.g_f06 (vrownumber), '0') <> 'Y'
THEN
UPDATE emp_garbage
SET check_char = 'Y'
WHERE empno = HTMLDB_APPLICATION.g_f01 (vrownumber);
END IF;
END LOOP;
-- remove old checkboxes
FOR ii IN 1 .. HTMLDB_APPLICATION.g_f06.COUNT --why is this used?
LOOP --
-- only if the checkbox was already set
IF HTMLDB_APPLICATION.g_f06 (ii) IS NOT NULL
THEN
vfound := FALSE;
FOR jj IN 1 .. HTMLDB_APPLICATION.g_f07.COUNT -- your checkbox
LOOP
-- is the checkbox still checked?
IF HTMLDB_APPLICATION.g_f07 (jj) = ii
THEN
vfound := TRUE;
EXIT;
END IF;
END LOOP;
IF NOT vfound
THEN
UPDATE emp_garbage
SET check_char = 'N'
WHERE empno = HTMLDB_APPLICATION.g_f01 (ii);
END IF;
END IF;
END LOOP;
-- do the rest of the update
FOR i IN 1 .. HTMLDB_APPLICATION.g_f01.COUNT
LOOP
--are these references to column numbers?
--if so, does it matter if they are hidden or not?
UPDATE emp_garbage
SET ename = HTMLDB_APPLICATION.g_f02 (i),
job = HTMLDB_APPLICATION.g_f03 (i),
sal = HTMLDB_APPLICATION.g_f04 (i),
comm = HTMLDB_APPLICATION.g_f05 (i)
WHERE empno = HTMLDB_APPLICATION.g_f01 (i);
END LOOP;
COMMIT;
END;
------------------code ends
More questions: Are the HTMLDB_APPLICATION.g_f?? values dependent on the query order or the order that is displayed in the report?
Denes is using a field check_char to hold the value, and I am using a field called approval. I also do not want fields (other than the 'approval' field to be updateable from the [updateable] report. Denes is using updateable fields in his example, and if I set a field to be a report field rather than editable, the app breaks. Why?
I have read the documentation on the checkbox function, but it does not help a lot; and I have not found other explanations in this forum.
thanks in advance!
Mike
P.S. Would it be possible to combine the click event in the checkbox to automatically post the change in the db? Presuming that this takes javascript, is this type of thing hard to do?

Mike,
irst I am wondering what version of Apex and Oracle
you are using as the example you are phising around
in was written for Apex 2.2 (HTML DB). 3.1
>
You should not have any issues but it is good
practice to recode the HTMLDB_APPLICATION to
Apex_APPLICATION.
agreed.
Specific to your questions: Are the
HTMLDB_APPLICATION.g_f?? values dependent on the
query order or the order that is displayed in the
report? I am not sure what you mean by order that is
displayed, but if you mean the position of the item
.g_f(#) then yes. This refers to the position in the
field, example your query has 6 outputs labeled
1 = .g_f01
2 = .g_f02
3 = .g_f03
4 = .g_f04
5 = .g_f05
6 = .g_f06
As to the next question, "I also do not want fields
(other than the 'approval' field to be updated from
the [updated] report. Denes is using updated fields
in his example, and if I set a field to be a report
field rather than editable, the app breaks. Why?" What I meant about the order is that you can change the display order in the report (select the report attributes tab from the report region and toggle the display order) and not change the order in the original query. Is it the query order or the display order that matters? As for the example report itself, I refer you to Denes' example. He has 10 fields total, and 6 are editable, two are hidden.
I would actually need to see how you have written this
portion of the query as for myself I would have the
querried and displayed normally and not address it as
.g_fXX.
I have not written it...
Here is the query from Denes application:
SELECT empno, empno empno_display, ename, job, sal, comm, check_char,
HTMLDB_ITEM.checkbox (7,
'#ROWNUM#',
NULL,
DECODE (check_char, 'Y', '#ROWNUM#')
) check_box, check_char checkbox_display
FROM emp_garbage
and ot your last question;
P.S. Would it be possible to combine the click event
in the checkbox to automatically post the change in
the db? Presuming that this takes javascript, is this
type of thing hard to do?
Yes is the simple answer, you have the option under
the edit region to allow an end user to update the
form as well as write into the code the option to
update the Database directly with something as simple
as a button.
Hope this helps,
Randy

Use of Checkboxes on reports

Hi
I am using the HTMLDB_ITEM.CHECKBOX function. It works fine in the report, as below;
SELECT
"POOL_CARS"."ID" "ID",
"POOL_CARS"."REG_NUM" "REG_NUM",
"POOL_CARS"."MAKE" "MAKE",
"POOL_CARS"."BHP" "BHP",
"POOL_CARS"."PURCHASE_DATE" "PURCHASE_DATE",
"POOL_CARS"."MODEL" "MODEL",
"POOL_CARS"."COLOUR" "COLOUR",
"POOL_CARS"."STYLE" "STYLE",
"POOL_CARS"."PRICE" "PRICE",
"POOL_CARS"."AVAILABLE" "AVAILABLE",
HTMLDB_ITEM.CHECKBOX(1,"AVAILABLE",
DECODE(AVAILABLE,'Y','CHECKED',null)) "Av ",
"POOL_CARS"."DEPT" "DEPT"
FROM
"#OWNER#"."POOL_CARS" "POOL_CARS"
I want to use the checkbox to cause an update to the table (set Avail to Y where the box is checked, and to N for all other rows). So I have then created a submit button and a process to be run as follows
FOR I in 1.. HTMLDB_APPLICATION.G_F01.COUNT LOOP
UPDATE POOL_CARS
SET available = 'Y'
WHERE ID = to_number(HTMLDB_APPLICATION.G_F01(i));
htp.p('debug' || HTMLDB_APPLICATION.G_F01(i));
END LOOP;
I have a few problems here.
1. When the page is run the check boxes show up fine. When submit is pressed I get
ORA-01722: invalid number.
2. The line 'htp.p('debug' || HTMLDB_APPLICATION.G_F01(i));' does not seem to do anything !
3. I do not understand how to connect the current line within the loop to an actual row as the where clause is not realistic.
Can anyone help.? .

Jelane,
You have to reference the "ID" in your htmldb_item.chekbox api:
htmldb_checkbox(1,"ID",.....
Hope this helps,
Jos

Checkbox in tabular form - help needed

I'm trying to build a tabular form, with a checkbox for a field that can have value 'Y' or 'N'. Adding the checkbox is no problem, with the htmldb_item.checkbox API.
However, processing it is.
On this forum I found a way to process the checkboxes, by looping through all the records (with the help of htmldb_item.hidden in which the id is stored) and reading the value from the checkboxes and updating the column if the checkbox is checked. (see Re: Report with updateable checkbox)
however, as soon as I add a htmldb_item.hidden item, I receive the following error when I submit the tabular form to the Multi Row Update process:
"Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. "
My query:
Select id
,htmldb_item.hidden(1,id)
,htmldb_item.checkbox(2,id, decode(field, 'Y', 'CHECKED', NULL))
from table
What am I doing wrong?
is there a better way to process a tabular form with checkboxes?
Or should I process all the rows manually by updating every record even if it hasn't changed (with a loop through all the records)?

Tonnie, did you ever get an answer to this question?

Report with Checkbox

I am trying to follow the example shown at the below link but it is not working. I am modifying some of the code since I am using version 1.6. Any ideas as to what I may be doing wrong. The checkbox appears and I can select and deselect items but I cannot get P6_HOLDER to hold any of the values of the selected items. Thanks!
http://apex-smb.blogspot.com/2009/01/apex-report-with-checkboxes-advanced.html
First I created a page item called P6_HOLDER.
Next I created a report region (sequence 40) with the below code.
select htmldb_item.checkbox (1, dev_obj_id, 'onchange="spCheckChange(this);"',
:P6_HOLDER, ':') checkbox, dev_id, dev_obj_desc from edm_dev_obj where
dev_id = :P6_TEMP_DEV_ID
**I then created a html region (sequence 1) with the below code**
<SCRIPT src="http://www.google.com/jsapi"></SCRIPT>
<SCRIPT>
// Load jQuery
google.load("jquery", "1.2.6", {uncompressed:true});
function spCheckChange(pThis){
var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=CHECKBOX_CHANGE',$v('pFlowStepId'));
get.addParam('f01',pThis.value); //Value that was checked
get.addParam('f02',pThis.checked ? 'Y':'N'); // Checked Flag
gReturn = get.get();
$f('checkListDisp').innerHTML=gReturn;
</SCRIPT>
CHECKBOX List:
<DIV id=checkListDisp>&P6_HOLDER.</DIV>
I then created an application process on Demand called CHECKBOX_CHANGE with the below code
DECLARE
v_item_val NUMBER := htmldb_application.g_f01;
v_checked_flag VARCHAR2 (1) := htmldb_application.g_f02;
BEGIN
IF v_checked_flag = 'Y' THEN
-- Add to the list
IF :P6_HOLDER IS NULL THEN
:P6_HOLDER := ':' || v_item_val || ':';
ELSE
:P6_HOLDER := :P6_HOLDER || v_item_val || ':';
END IF;
ELSE
-- Remove from the list
:P6_HOLDER := REPLACE (:P6_HOLDER, ':' || v_item_val || ':', ':');
END IF;
-- Just for testing
HTP.p (:P6_HOLDER);
END;

Hi
Create a page level validation (fucntion returning boolean) and write code similar to following
DECLARE
v_count NUMBER := 0;
BEGIN
FOR i IN 1..APEX_APPLICATION.G_F01.COUNT LOOP
IF APEX_APPLICATION.G_F01(i) IS NOT NULL THEN
v_count := v_count + 1;
END IF;
END LOOP;
IF v_count = 0 THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
END;I take it your report query is similar to following
select apex_item.checkbox(1,"PK_CLMN") Tick, col2, col3 FROM tbl_nameCheers,
Hari
