Update Hidden Item In Manual Tabular Form

Apex 3.2
I have a column in my tabular form which is used in an update.
APEX_ITEM.DISPLAY_AND_SAVE(34,f.qtyuser) oldqtyuser
I do not want the users to see this column, so on my edit report I unchecked the Show checkbox.
Now I get an error message and my update fails.
I have tried changing it to
APEX_ITEM.TEXT(34,f.qtyuser,10,6) oldqtyuser and unchecking the Show checkbox but still it fails.
I have tried changing it to
APEX_ITEM..HIDDEN(34,f.qtyuser) oldqtyuser and unchecking the Show checkbox but still it fails.
How do I achieve this

Hi Gus,
Struggling to remember what is available in 3.2. What I did in this version was to append the hidden item to another item in the table. So for example if you have a text box in the table then use:
APEX_ITEM.TEXT(33,f.othercol,10,6)||APEX_ITEM.HIDDEN(34,f.qtyuser)
That way there is not extra column, but the hidden item is still displayed in the table.

Manual tabular form and hidden fields

Hi,
I have a manual tabular form with some hidden fields, one for the primary key and one to handle my checkbox.
The checkbox handling I got from here:
http://htmldb.oracle.com/pls/otn/f?p=31517:123:4202825883202781:::::
Here you can see my very simple example:
http://apex.oracle.com/pls/otn/f?p=22968:3:4142231640027285:::::
My query:
select
to_char(dag,'day dd mon yyyy') dag
, HTMLDB_ITEM.HIDDEN(1,pk) pk
, htmldb_item.text(2, ben1) ben1
, htmldb_item.text(3, ben2) ben2
, htmldb_item.text(4, ben3) ben3
, htmldb_item.text(5, ben4) ben4
, htmldb_item.hidden(6, cb1) cb1_hidd
, htmldb_item.checkbox(7, ROWNUM, NULL,DECODE (cb1, 'Y', ROWNUM)) cb1
from dummy
My problem is that I don't want to show the columns hidden_pk and hidden_cb1. But if I set them to not shown they are not parsed in my html page. Maybe that's all natural but how do I handle this problem??
Any ideas?
Regards Daniel

Stick them to another item, like this
select
to_char(dag,'day dd mon yyyy') dag
, htmldb_item.text(2, ben1) || HTMLDB_ITEM.HIDDEN(1,pk) ben1
, htmldb_item.text(3, ben2) ben2
, htmldb_item.text(4, ben3) ben3
, htmldb_item.text(5, ben4) || htmldb_item.hidden(6, cb1) ben4
, htmldb_item.checkbox(7, ROWNUM, NULL,DECODE (cb1,
'Y', ROWNUM)) cb1
from dummy

How to update Manual Tabular Form

Hi There,
I have a manual tabular form on an apex 4.1 page and I would like to update the records when I click on a submit button.
Below is the query of the form:
SELECT '#ROWNUM#' sno,
apex_item.checkbox(01, wo_line_id) del,
apex_item.hidden(02,wo_line_id)||apex_item.hidden(03,wwv_flow_item.md5(adjusted_amount)) wo_line_id,
apex_item.text(17, adjusted_amount, 10, 10,'onchange="set_innerHTML(this);"','f17_' ||'#ROWNUM#') adjusted_amount
from work_order_lines
where wo_header_id = :P302_WO_HEADER_ID;
Below is the code in the "After Submit" process
DECLARE
v_header_result VARCHAR2(1);
v_line_result VARCHAR2(1);
v_error_count NUMBER:= 0;
BEGIN
FOR i in 1..apex_application.g_f02.COUNT
LOOP
BEGIN
update_wo_lines_prc(:APP_USER
,:P302_WO_HEADER_ID
,APEX_APPLICATION.G_F02(i)
,APEX_APPLICATION.G_F17(i)
,v_line_result);
END;
END LOOP;
COMMIT;
END;
Somehow the LOOP doesn't get executed.
Please advise.
Thanks
Yogi

Hi,
I found the reason for this.
For the column wo_line_id the show option in the report attributes was not checked.
Thats why apex_application.g_f02.count is returning 0 and the loop was never executed.
Thanks
Yogi

How to Multi Row Update function in Manual Tabular Form

Hi All,
In my application I am using manual tabular form, for Update and insert i have written pl/sql process,
but i want to make use of MULTI_ROW_UPDATE function for update and insert operations.
How can I implement default tabular form behaviour in manual tabular form.
I am using:
Oracle Database 11g
ApEx Version 4.0
please help me, it's urgent.
thanks
MR

Hi Joao,
First Can u pl let us know your view is based on how many
tables?
If it is a simple view ,you can open the form in update mode
passing a parameter to it thru a procedure or thru a url or what
ever you feel like(form to form,etc)..I will give you an example
on how to open the form in update mode like below..
1.develop a form based on a simple view
2.Call that form Thru a simple URL
3.In the above you are opening a form with module id
ex:1234567890 in update mode and change portal30 to suit
accordingly..
4.You are passing a parameter called "ABCDEF" TO "NAME" Field to
that form for querrying..
5.Now the form will be opened in update mode and all the fields
are pertaining to the parameter "ABCDEF" and you can update the
fields....
II..Now regarding the check boxes i need to know which version
of the portal are u using..As for as my knowledge goes (up to
3.0.6) there are lot of bugs with the check boxes and check box
checked value is always "yes"(if u want to insert in to the data
base).So try not to depend on checkboxes and instead Combo is
the right answer till oracle portal is free of bugs.
No triggers are required for your requirement....
Hope i have answered your problem ...If any please revert back
with full details
Thanks

how it is created.i have no idea related textfield with autocomplete.Please help me....

I understand that the add row button is currently doing a submit.
To not submit the page you need a dynamic action on the page.
Does the javascript function addRow do what you want?
Otherwise have a look at the following two threads Add row in manual tabular form using dynamic action and Accessing Tabular Form & Add Elements to Collection without Page Submit.
You're process could be something like:
Add the new values to the collection using the idea's in the second thread and at the same time add the new row.
And as second action refresh your tabular form.
If you get stuck set up what you have done on apex.oracle.com using the tables from the demo application.

Manual Tabular Form - Items not rendered

Hi,
i'm trying to build a manual tabular form:
I added a blnak page with a Report Region using a SQL Query in a Classic Report:
select apex_item.text(1,"EMPNO") as "EMPNO",
apex_item.text(2,"ENAME") as "ENAME",
apex_item.text(3,"JOB") as "JOB",
apex_item.text(4,"MGR") as "MGR",
apex_item.text(5,"HIREDATE") as "HIREDATE"
from "EMP" "EMP"The items are not rendered in the report, but the HTML Text is displayed instead.
See http://tinypic.com/r/2e6bqdu/5
I played around with "Display As" in the Column Attributes - no luck.
I used this links as reference:
http://apex.oracle.com/pls/otn/f?p=31517:170:2228543603318893:::::

http://apexjscss.blogspot.com/2010/05/manual-tabular-form.html
Am i missing something ?
APEX 4.1 on 11gr2
regards,
gw

The "Display As" for each column should be "Standard Report Column".
Seems the default "Display as" for standard reports has changed:
I created your standard report in a 3.2 environment and the report defaulted the "Display As" for each column to "Standard Report Column".
I created your standard report in my own 4.0 environment and in the hosted apex.oracle.com environment and the report defaulted the "Display As" for each column to "Display as Text (escape special characters, does not save state)"

Can't get Delete Process to work on Manual Tabular Form

please help me in solving this.The same code its good for one tabular form and for the other it giving the checksum error.
Thanks in advance

Hi patrick,
Thanks for the reply i am getting the checksum error even if i used my primary key in the select statement of the MD5 checksum.
My primary key in the second tabular form is
htmldb_item.hidden(12,ECGEXT_ID) ECGEXT_ID
so i changed the process to:
for i in 1..htmldb_application.g_f12.count
loop
if htmldb_application.g_f12(i) is not null
then
select wwv_flow_item.md5(ECGEXDT_ID,LEAD_CD,T_ID,ENTERED_DTS,ENTERED_BY_MSPR_ID) cks
BULK COLLECT INTO l_cks
from ECGEXT where ECGEXT_ID = htmldb_application.g_f12(i);
-- Compare the original checksum, l_cks,
-- with submitted checksum, htmldb_application.g_fcs.
-- If they are different, raise an error.
if htmldb_application.g_fcs(i) != l_cks(i) then
-- val1 := htmldb_application.g_fcs(i);
-- val2 := l_cks(i);
-- insert into test2 (val_1,val_2) values (val1,val2);
rollback;
raise_application_error(
     -20001,
     'Current version of data in database has changed '||
     'since user initiated update process.');
end if;
end if;
end loop;
It's not possible to use BULK COLLECT to get the MD5 checksum of all >>>rows. Because the index positions in the MD5 array and the >>>apex_application.g_fxx array index will probably not match, especially if you >>>don't order or if you are on a second page.How come the first tabular form is running i used the bulk collect in the first tabular form
HERE IS THE CODE FOR THE FIRST TABULAR FORM:
-- Get original MD5 checksum
select wwv_flow_item.md5(ECGEXDT_ID,LEAD_CD,ST_ID,ENTERED_DTS,ENTERED_BY_MSPR_ID) cks
BULK COLLECT INTO
l_cks
from ECGEXST where ECGEXDT_ID = :P65_ECGEXDT_ID;
-- Compare the original checksum, l_cks,
-- with submitted checksum, htmldb_application.g_fcs.
-- If they are different, raise an error.
for i in 1..l_cks.count

htmldb_application.g_f14(i)
used the same code.

Have you got any response on this? I would like to know how to do it too. I am trying to implement a manual tabular form on a page and need this functionality.
I do know one thing. After attending the ODTUG conference last week, Raj said something about you have to process check boxes and radio groups separately from the rest of the form.
Thanks,

Select List in Manual Tabular Form based on a previous column

I have a manual tabular form that have several columns One column (vendor) is a select list that should be based on a previous column (Vendor Type - Internal/External). So if the user selects Internal for Vendor Type, the Vendor column's select list should only contain those vendors with type of Internal. By the way, it also uses APEX collections.

Display select list from query on manual tabular form

Hello,
I'm trying to display a select list from query on a manual tabular form. I'm using a collection to store the data. I can't seem to get the query to work. I can display the item as a text item. Any help would be appreciated. Thanks, Elizabeth.

I got so frustrated I started over. I'm following the how to create a manual form.
http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html#MANUAL
The problem I'm now having is even though I display items as hidden, there is a column holder on the report for them. If I go into the report attributes and toggle the show attribute off I cannot reference an items value in my logic. I used /&nbsp/ for the column heading but I still get the little sort arrow where the column heading should be. I tried to toggle the sort attribute off but the sort arrow still shows up. How can I use the apex_item.hidden and not get a place holder for the column on a report? Thanks, Elizabeth
Here is the code I'm using to generate the report:
select x.ceah_people_lang_id,
x.language_id,
x.proficiency,

Two Manual Tabular forms in a same page

Since i have to create two tabular forms in a same page, i created tabular forms manually.
Both the forms are working fine if the columns are not defined as conditional display.
Based on item value set by user, few fields should be either displayed as text field (editable) or read only (display).
I created two columns for a same field one as editable another one as non editable.
Based on item value any one of the column will be displayed.
Since the manual tabular form update process is using 'apex_application.g_f02', if any one of the column is not visible,
multiple row update is failing.
can any one please help me or suggest me to solve this.
Edited by: Ravi on Apr 19, 2012 9:02 AM

I'm guessing you have a page item that is used to control display of the columns as display only or editable.
If that's true and the page item tells you to display the editable column, then you end up with say a g_f02 and a g_fo3, where you otherwise might only have a g_fo2.
Use the value of the page item in your update process to control which tabular form element to use.

Question about manual tabular forms

Hello. I have a manual tabular form which has a some select_list_from_query items, text_from_lov_query, hidden, etc. I have not found a way to have one of the select lists based on one of the hidden items. Is it possible for the select list query to use other items from the form's select statement? In the code sample below I would like group_number to be based on the board_group_type_id.
Thank you,
-Carmine
select
htmldb_item.hidden(4,board_group_type_id) board_group_type_id,
htmldb_item.select_list_from_query(7,group_number,
'select m.valid_group_number d, m.valid_group_number r
   from board_group_type b, map_group_numbers m
   where b.board_group_type_id = m.board_group_type_id
     and b.board_group_type_id = '|| TO_CHAR(board_group_type_id) ||
' order by 1',
NULL,'NO') group_number
from board_groups
where system_id = :P0_PROFILE_NAME

Bump...Anyone?
Thank you,

Manual tabular form - popup

I have a couple of problems with the manual tabular form I have created and would appreciate some help,
First the htmldb_item.popup_from_query is not populating the field when I select the item:
The query looks something like this:
Select x.data1,
x.data2,
x.data3,
x.CKS
From (
Select htmldb_item.display_and_save(1, data1) data1,
htmldb_item.text(3, data2, 50) data2,
htmldb_item.select_list(4,data3,'Yes;Y,No;N') data3
htmldb_item.md5_checksum(data1,data2, data3) CKS
FROM my_table
UNION ALL
Select htmldb_item.popup_from_query(1, NULL, 'select code || CHR(45) || description descrip, code from PRODUCT_STREAM', 2, 2) data1,
htmldb_item.text(3, NULL, 50) data2,
htmldb_item.select_list(4,'N','Yes;Y,No;N')data3,
htmldb_item.md5_checksum(null,null,null) CKS
FROM dual
) x;
When this page is run, the existing data is displayed with a blank line at the bottom as expected, it I click on the popup icon a list of codes is displayed, but I cannot click on any of the items to populate the data1 field. If I change the query on the top of the union so the first data1 is also htmldb_item.popup_from_query then it works fine, but data1 cannot (user requirement) be changed by the user, how can I fix this so the popup list works.
Second thing:
CKS is showing as another column in the tab form, if I uncheck show it doesnât work anymore, there us no data showing in the column just the heading, and I can get rid of the text but there is still allocated size for it.

Why do you have to write the tabular form manually? Why not use the tabular wizard and have the form, including checksums, generated for you? In HTML DB 1.6 you can include options to automatically add new empty rows to your tabular form and have a row selector with delete functionality.
Neither the manual tabular forms nor the automatically generated tabular forms support mixing display types for columns. Having a display-and-save display type for existing rows and a popup for new rows doesnât work. All rows, including new ones, have to use the same display type to work properly. If itâs a requirement to have this data1 column be read-only for existing rows, then you need to create a separate form for adding new rows. So e.g. you could have a tabular form only for existing data and an add-row button that takes the user to a data entry form on another page.
Youâre checksum btw shows up in itâs own column because you defined it to be an extra column in your SQL statement. Since itâs just rendering a hidden form field, you could append the checksum to another column:
htmldb_item.select_list(4,'N','Yes;Y,No;N') ||
htmldb_item.md5_checksum(null,null,null) data3
When using manual tabular forms, the column alias names are irrelevant. But again, Iâd recommend using the built-in functionality.

Manual Tabular Form using checksum

I have a manual tabular form which updates OK but when I add the htmldb_item.mds_checksum it does not always work. It does not pass the MD5 checksum test in the update process. Sometimes it works some times it does not. No one else is updating this data so it should pass the checksum error.
I need a manual tabular form so I can to retrieve this same data in a collection if the page is submitted for a cascading dropdown in another region. That is correct?
Of course, I could do the cascading dropdown another way instead of select list on submit. This is puzzling me.
Here is the sql query:
select htmldb_item.hidden(1,sub_id) sub_id,
htmldb_item.display_and_save(2,column_id) column_id,
htmldb_item.display_and_save(3,column_name) column_name,
htmldb_item.display_and_save(4,primary_key) primary_key,
htmldb_item.display_and_save(5,required) required,
htmldb_item.select_list(6,isselected,'Yes;Y,No;N') isselected,
htmldb_item.md5_checksum(isselected) cks
from sub_columns
where sub_id = :P26_SUB_ID
order by 2
Here is the update process:
declare
l_cks wwv_flow_global.vc_arr2;
j pls_integer := 1;
begin
-- Get original MD5 checksum
select wwv_flow_item.md5(isselected) cks
BULK COLLECT INTO
l_cks
from sub_columns
where sub_id = :P26_SUB_ID;
for i in 1..l_cks.count
loop
if htmldb_application.g_fcs(i) != l_cks(i) then
rollback;
raise_application_error(-20001,
'Current version of data in database has changed '||
'since user initiated update process.');
end if;
end loop;
-- update Subscription
for i in 1..htmldb_application.g_f01.count
loop
update sub_columns
set isselected = replace(htmldb_application.g_f06(i),'%'||'null%',NULL)
where sub_id = :P26_SUB_ID and
column_id = htmldb_application.g_f02(i);
end loop;
commit;
end;
Any help would be appreciated. I just don't see what I am doing wrong and I don't see any other way to do it.

I had already read this paper before doing the tabular form manually. I tried to follow it as closely as I could. My tabular form is a little different since I have a where clause in my SQL and only updating one field. The other fields are display_and_save. And I was branching to a different page than the page containing the tabular form. I would think none of these differences should make it not work. I did change to branch to the same page. That made no difference.
I did not need to do an insert so I skipped doing that step and then went to Adding Optimistic Locking. It is failuring in my update process with this code:
-- Get original MD5 checksum
select wwv_flow_item.md5(isselected) cks
BULK COLLECT INTO
l_cks
from sub_columns
where sub_id = :P26_SUB_ID;
for i in 1..l_cks.count
loop
if htmldb_application.g_fcs(i) != l_cks(i) then
rollback;
raise_application_error(-20001,
'Current version of data in database has changed '||
'since user initiated update process.');
end if;
end loop;
I get the Error process message and then the above -20001 error message when I click on the Submit button. Is there something wrong with my above code? I would assume I would need to add the where clause to the above select since I am only updating whose records.
I had created a submit button with action submit page and redirect to URL. The process executes on the condition when the submit button is pressed.
I need to get this working soon. I would assume other people have done a similar thing. I have tried many things. Another thing I notice is if I tell it to not display the first column, sub_id, and the last column, cks, (unselecting display in Report Attributes section) then the update does not work. I must be doing something wrong but I don't know what.
I created the page with component, report, SQL Report, and region type SQL Query.
