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

Manual tabular form and query based LOV

Happy new year everyone!
Okay so, I've run into an error when making one of the fields in a tabular form into a select list.
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
The query works fine in SQL Workshop and Toad, it returns over 100 rows.
I have tried to use a Popup LOV, which works but I'd like to know what is going wrong with the select list.
We're using version 3.0.1.00.07 of apex, for what it's worth.
Help appreciated!

Keiran,
In the select list there is a display value and a return value.
The return value is the Foreign Key and the Display value is what is displayed in the LOV.
Are you getting these the wrong way round ?
I usually put the return value first and alias is with r and put the display value second and alias the display value with d.
Hope this helps
Regards

Sort Nulls First with Manual Tabular Form????

I just created a manual tabular form and it appears to be in working order. Now I need to order the report results on 2 columns (which I have working using the sort sequence in the column attributes), but I also need the blank row (added row) to appear on top of the results.
What do I need to do to add the blank row on top?? Sort Null: First does not work in my case.
Thank you,
Tammy

Primary key column in manual tabular form

I am creating a manual tabular form and am unsure what to do for my primary key column. When I do this with the wizard, I'm allowed to specifiy a Primary Key Source Type and the Primary Key Source (my sequence). Is there a way to do this in a manual tabular form?
I'm creating the column with the call 'wwv_flow_item.display_and_save(2,hours_id) hours_id' but when I edit the 'Tabular Form Element' section, I don't have the Primary Key fields anywhere to edit...only Reference Table Owner, Reference Table/Column Name. Where can I specify the sequence?
Thanks,
Janel

In the process ApplyMRD, try specifying the 'Secondary Key Column' in the section 'Source: Multi Row Update and Delete' to the second key column in the tabular form.
I haven't tested this with your situation, but worth a shot.

Manual Tabular Form Problem

Apex 3.2
I have written a manual tabular form and it has a validation to check if a column contains negative numbers.
If it does then it returns a validation error.
I also have the same validation in my database procedure which raises
RAISE_APPLICATION_ERROR(-20000, 'The update procedure does not accept negative numbers.');My problem is withmy page validation.
If the column value was 16 and the user types in, eg, -12, then the validation fires and returns the message.
The problem is that once the message is returned, the column value is reset to the original value, eg, 16.
If I disable my page validation and use my database exception.
Then the error message from the database displays. If I click ok, then the form displays the new value, eg, -12.
I want to use my page validation, but I need the page to show the new value.
I have made all my processes and branches conditional to run only if there are no inline validations displayed,
but this did not affect anything.
Any help appreciated

It works exactly how I want mine to, without using collections, ie, it keeps the new values in the page.
Unfortunatley I cannot figure out how he does thatUpgraded to 4.2 ;)
One of the differences between version 3 and 4 is that retaintion/caching of the changed values in tabular forms.
In other words in apex 4 the builder takes care of showing the new changed value.
By not fetching the data from the database on a validation error.
Where as in Apex 3 you have to do that when there is a validation error and the message is shown on the same page.
The report fetches the data from the database even when there is a validation error.
There are 2 options
1) Let the validation message be shown on the error page. Going back in the browser history doesn't fetch the data form the database up on rerendering.
This option is mentioned in the thread the demo was inspired by.
2) Work with a collection. Where you take care of the caching. This method gives the posibility to so multiple validation messages where as the "show on error page" shows only one validation message.

Help- I have added a field in my tabular form and now i get an error in mul

Help- I have added a field in my tabular form and now i get an error in muli update form; Here is the error, how do I go in to change the process, adding the extra field??

Hi,
I believe the error is due to the checksum process which doesn't have that additinoal field's information. You can try creating the form again with the additional field, or if needed you can go with the Manual tabular form.

Manual tabular form -- add rows

Hi everybody, I am making a manually tabular form following the Denes Kubicek tutorials:
http://apex.oracle.com/pls/otn/f?p=31517:170:1304244099066416::NO
and
http://apex.oracle.com/pls/otn/f?p=31517:190:1304244099066416::NO
The SQL for the tabular form is:
SELECT apex_item.checkbox (31,
idint,
'onclick="highlight_row(this,' || ROWNUM || ')"',
NULL,
'f31_' || LPAD (ROWNUM, 4, '0')
) delete_checkbox,
idint,
apex_item.text (32,
tipus_modif,
1,
1,
'style="width:20px" ',
'f32_' || LPAD (ROWNUM, 4, '0')
) tipus
FROM GPPC_DETALLS_ESMENA_PROP_V
where esmena_idint = :P18_IDINT
and tipus_modif ='A'
The Report is created correct. Now I modify the "Form Region" template like this:
<table class="t6FormRegion" id="MY_TAB" border="0" cellpadding="0" #REGION_ATTRIBUTES# summary="">
<tr><td class="t6Header">#TITLE#</td></tr>
<tr><td class="t6ButtonHolder">#CLOSE# #PREVIOUS##NEXT##DELETE##EDIT##CHANGE##CREATE##CREATE2##EXPAND##COPY##HELP#</td></tr>
<tr><td class="t6Body">#BODY#</td></tr>
<tr><td><img src="#IMAGE_PREFIX#themes/theme_6/t.gif" width="400" height="1" alt="" /></td></tr>
</table>
Now I add a Button URL with the code:
javascript:va_AddTableRow(this,'MY_TAB',1);
and add this Javascript in the region header of the SQL Report
<script>
function va_AddTableRow(pThis,pThat,pNum){
var tt = html_GetElement(pThat);
for(i=0;i<pNum;i++){
var ogTR = tt.rows[1];
var trClone = ogTR.cloneNode(true);
trClone.firstChild.innerHTML='(null)';
var last_child=trClone.lastChild.getElementsByTagName('input')
for (var j=0;j<last_child.length;j++)
if (last_child[j].type=="hidden" && last_child[j].name=="f01")
last_child[j].value="";
if(document.all){
myNewRow = tt.insertRow(tt.rows.length);
oReplace = myNewRow.replaceNode(trClone);
}else{
tt.appendChild(trClone);
</script>
In this moment, when I push the botton appears the text (nulll) in the same region but not as a new line in the SQL report, what is the problem??
Thank you for your help

Alberto,
When you get a chance, see if maybe this (old version) of my app does something similar to what you need/want.
[http://apex.oracle.com/pls/otn/f?p=26115:3]
It's not working right now though, I keep getting the Oracle error:
ORA-01116: error in opening database file 17252 ORA-01110: data file 17252: '/u03/oradata/marvlprd/MARVLPRD/datafile/o1_mf_flow_172_23qtsjpr_.dbf' ORA-27041: unable to open file Linux Error: 23: Too many open files in system Additional information: 3
So, as way of an explanation (until Joel gets the Linux process fixed), I have a simple little screen that I use for letting the users specifiy search criteria. Each line has four columns, what field they want to search, a condition (equals or not equals), the text to search for, and an optional 'And/or' argument. If the 'And/Or' gets populated, a new blank line automatically gets created. There is also a red 'X' on each line so they users can delete a line if they want.
Not sure if this is what you need, but this page uses the same set of javascript code, so perhaps when it's working again, you can see if there are any similarities or differences.
Also, for reference, so you can see the code and variables, etc., the workspace is wbfergus, and the id and password are both htmldb-apex.

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.

Marc

Manual Tabular Form Formatting Questions

Hello, this is my first time using a tabular form and am now trying to tackle creating a manual tabular form. So, now I have some questions on formatting.
1. Is it proper on this forum to lump several similar questions together or should these be separate postings?
2. I have a hidden column that I do not want to display on the screen at all. However, I need access to the column later when saving. I am currently using the htmldb_item.hidden function to retrieve the field. This works. However, the column still displays but the value does not display. I then tried to uncheck the show attribute for the column to unchecked. Unfortunately, if this is not selected, when using the htmldb_application.g_f01 function, I would receive an error as if the column did not exist. How do I make the column totally hidden so that it does not display at all?
3. I have a number column where I want the column to display in dollars (i.e. $100, 000). I tried to set the number format on the column in the report attributes. However, no luck. To retrieve the column, I am using the function htmldb_item.text to retrieve the column. I am not sure if I should be able to format the column in the report attributes or if the htmldb_item.text function has a parameter that I could use for formatting. Suggestions?
4. Similarily, I would like to right justify this column. How is this accomplished?
Thanks

Hi everyone,
Is there any way to not to display the hidden columns in the manual tabular forms,when we create the manual tabular form using htmldb_item.hidden.
But need to refer that column in the process.
In the wizard generated tabular form if the column is of type HIDDEN we dont see that column on the report.
How can i achieve the same in manual tabular forms..
Thanks

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.

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

Apex_item.radiogroup using an LOV in a manual tabular form

I'm on APEX 4.0.0.00.46 and I'm sure there must be an obvious solution that I'm missing here, but I'm having a problem setting up an apex_item.radiogroup on a manual tabular form. This is the basic query that I'm using:
select apex_item.radiogroup(37,my_field) as my_field
from my_table
When I use the above query as my Region Source, it compiles fine. However, it seems as though the query won't pull in the value that currently exists in the table unless I set the Column Attribute called 'Display As' for the field to 'Standard Report Column'. When I do this, it seems to remove the capability to incorporate a LOV into the radio group. I'm attempting to incorporate a query like this into the radiogroup:
select 'YES' d, 'Y' r
from dual
UNION ALL
select 'NO' d, 'N' r
from dual
So, to recap, I can set up a Radio Group (query based LOV), but if I do, the query of the table will not pull in the current value from the table. If I change the 'Display As' Column Attribute to 'Standard Report Column', I can no longer incorporate the LOV. Please help if you have any ideas.

I am not 100% sure what you are trying to do but I think I am close. Try using
SELECT apex_item.radio_group_from_query
          (37,
           my_field,
           'SELECT ''YES'' d, ''Y'' r FROM dual
            UNION ALL
            SELECT ''NO'' d, ''N'' r FROM dual'
          ) AS my_field

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
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.');
-- return;
end if;
end loop;

Delete Functionality in manual tabular form

Hi everyone,
I have created 2 tabular forms on the same page.everthing is working fine.Both the tabular form are able to insert and update.I am getting problem to implement the DELETE functionality in those tabular form.
I inserted this code htmldb_item.checkbox(6, id) del in the region and i created a delete process.But i am getting (no data found) error.
could anyone help me in solving this.
thanks
phani

I created the other tabular form on the same page with
htmldb_application.g_f11(i)
htmldb_application.g_f12(i)
htmldb_application.g_f13(i)
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,
Michelle
