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

Issue with APEX_ITEM.CHECKBOX in Manual Tabular Form report

Hi,
I have a simple manual tabular form report with query :
SELECT
APEX_ITEM.CHECKBOX(1,order_id) ,
APEX_ITEM.TEXT(3,Ord_number) ,
APEX_ITEM.TEXT(4,ord_flag)
from
tbl_order
and a process to update the value of Ord_number & ord_flag columns for the selected (Checked) rows.
FOR i in 1..apex_application.g_f01.count
loop
UPDATE
tbl_order
SET
Ord_number = apex_application.g_f03(i),
ord_flag = apex_application.g_f04(i)
WHERE
order_id = apex_application.g_f01(i);
END LOOP;
But the values getting updated wrongly , how can I ensure the exact values is retrieved in apex_application.g_f03(i) & apex_application.g_f04(i) ?
Regards.

I think the row selector is there if you create an tabular form. However, you can create it yourself following this example:
http://apex.oracle.com/pls/otn/f?p=31517:170
Basically,
apex_item.checkbox (30,
                           '#ROWNUM#',
                           'onclick="highlight_row(this,' || ROWNUM || ')"',
                           NULL,
                           'f30_' || LPAD (ROWNUM, 4, '0')
                          ) delete_checkboxDenes Kubicek

Query for create manual tabular form using apex collection using item textfield with autocomplete

can we create a manual tabular form inside item textfield with autocomplete ?
how it is possible?
with Apex_item API used for this item.
i used this code for creat cascading select list

but i want item in tabular form textfield with autocomplete and remove select list. my requirement is using textfield with autocomplete select a employee name and second item textfield with autocomplete display dependent perticular employee related multiple task.
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.

Sorting on date (date_popup2) in manual tabular form does not work

Hi All,
I created a manual tabular form (based on a collection) with 1 date_popup2 field in it. This field is defined in the query as follows:
,      apex_item.date_popup2( p_idx                   => 18
                            , p_value                 => c004
                            , p_date_format           => 'dd-mm-yyyy'
                            , p_item_id               => 'f18_' || lpad (rownum, 4, '0')
                            , p_item_label            => 'Start date'
                            ) as tf_br_start_date
In the report attributes I marked this column to be sortable.
However, in the page the sorting is not working. It looks like it's always sorted in the order of the seq_id.
Can anyone tell me how to solve this?
Regards,
René

I'd call it a bug/missing feature.
It appears that within a Basic report, sorting on a column created using APEX_ITEM.DATE_POPUP2() does not sort by date.
I'd file this with Oracle Support and see what they say.
Include a link to this thread and your workspace login information.
I got something to work by: (probably not what you want.)
using the C004 column directly. (I just added it to the SQL code)
setting the column's attribute "Display As" to "Date Picker"
setting the column's attribute "Number /Date Format" to DD-MM-YYYY
I suspect: since you don't start with p_idx => 1, this column becomes "1" ==> g_f01

How to add a new row at the top of manual tabular form

I have a manual tablular form. I'm trying to add a row at the top of the form, instead of new row of being displayed at the bottom. any ideas are appreciated.
thanks,
Surya

This will depend on two things:
1. sorting of the columns - needs to be a some kind of a descending sorting on a hidden column, enabled within the Report Attributes and not in the SQL Query
2. Report Attributes => Layout and Pagination => Sort Nulls First
You will need to play with those settings a bit. One thing to consider is that you should sort your report on a hidden column and you shuldn't enable the sorting on visible columns, because it will mess up your row positioning.
See this example:

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
phani

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;

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 (Multiple Tabular forms)

Hi,
I am using APEX v4.0.
In my application, I am having a few issues with the generation of a manual tabular form. I need two tabular form on the page so I have created the first using a wizard and the second through the use of a collection using skillbuilders tutorial at http://www.skillbuilders.com/webinars/webinar.cfm/49?title=Manual%20Tabular%20Forms%20in%20Oracle%20APEX:%20A%20Methodology%20that%20Works
Independently, they work as expected i.e. if I have a condition on the 1st tabular form to never display and only display the 2nd, it works fine and vice versa. However, if I try to try to display them both, I am getting errors.
When both forms are displayed and I make a change to the form generated by the wizard, I am getting the error 'ORA-01403: no data found'.
When both forms are displayed and I make a change to the form I generated manually, I am getting the error 'ORA-01722: invalid number'.
Can someone please suggest where I should be looking as independently they are working fine, but when they are both on the page together, they are not.
Thanks

Hi Nicollette,
I have got a bit further with it now thanks. The wizard form is now working when BOTH forms are displayed. I am still having a few issues with the manual one. When I try to insert a record I am getting:
ORA-01410: invalid ROWID
     Error
It is now letting me delete and update though.
I have the following as a before submit process:
DECLARE
   l_collection_name APEX_COLLECTIONS.COLLECTION_NAME%TYPE;
   l_original_md5    VARCHAR2(32);
   l_latest_md5      VARCHAR2(32);
BEGIN
   l_collection_name := 'QC_COMPLAINT_MODELS';

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

Problem in saving BLOB on a manual tabular form

Hi All,
I have a manual tabular form which has one column as file browse (blob). When I browse and select some file to save with the row, it saves only the name of the file, not the actual file.
The example form is available on apex.oracle.com. The page has a process called SAVE which is supposed to save the record with blob.
Workspace: bobforum
user: forum
password: abc123
Application: 39196
Page: 1
I will appreciate if someone can help.
Thanks,
Zkay

Hi,
What I did check, apex_application.g_fnn array do not work for this.
From Google I did found that it has work in previous APEX version.
Something has changed and e.g. Denis example for multiple file browser do not work anymore.
http://htmldb.oracle.com/pls/otn/f?p=31517:161
I did manage upload files to wwv_flow_files table when using apex_application.g_xnn.
I did add derived column to report. To HTML expression I did place
<input type="file" name="x0#ROWNUM#" />
This way you could have report that shows max 20 rows in pagination page.
But I did not find way to identify file uploaded to flow files.
In After submit process apex_application.g_xnn seems have null value,
so I could not query wwv_flow_files by name column and insert file to my own table.
Regards,
Jari

Manual Tabular form

Hi everyone,
I have created a maual tabular form with the help of (HOW TO) document in OTN.For that I wrote maual update and manual delete process and evething is working fine.But in the manual update process i did not include the code to compare the checksum of the submitted data with the old data (still its working fine).But in my application i have created several manual tabular forms like this .Do the application get any problem in the futher as i am not checking the checksum.If i compare the checksum i am getting error.I decoded that error by
inserting the checksum values to a (test table).The checksum values for a row is changing even if there is no change in the data of the table.
any suggestions please
Here is my code
declare
l_cks wwv_flow_global.vc_arr2;
j pls_integer := 1;
begin
-- Get original MD5 checksum
-- select wwv_flow_item.md5( column1,column2,column3,column4) cks
-- BULK COLLECT INTO
--l_cks
-- from table;
-- 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;
-- update EMP
for i in 1..htmldb_application.g_f07.count
loop
if htmldb_application.g_f07(i) is not null then
update table
set
column2 = replace(htmldb_application.g_f08(i),'%'||'null%',NULL)
where column1 = htmldb_application.g_f07(i);
else
if htmldb_application.g_f08(i) is not null then
insert into table
( column1 ,
column2,
column3)
values
replace(htmldb_application.g_f08(i),'%'||'null%',NULL));
end if;
end if;
end loop;
end;

Phani,
I don't understand what you have working, what does not work, and what that code does (much of it is commented out). Can you put an example on apex.oracle.com that shows the problem?

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.

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.
SELECT
-- Notice how I'm keeping the idx value the same as the column value in the collection. This helps to keep things organized
-- I also apply an id to each entry
-- I append the error value to the empname and sal
-- The Seq_id. Usefull when hiding rows (for delete) and then submitting from
apex_item.hidden(1,x.seq_id, null, x.seq_id || '_seq_id') ||
-- The Primary Key of the column
apex_item.hidden(2, x.ceah_people_id, null, x.seq_id || '_ceah_people_id') || x.ceah_people_id ceah_people_id,
-- Employee Name
case when x.seq_id = -1
then
apex_item.select_list_from_query (3,
NULL,
'select distinct language_name d, '
|| 'language_id r from foreign_language',
'style="width:170px" ' ,
'YES',
'0',
'- Select Language -',
'x.seq_id_' || LPAD (9900 + LEVEL, 4, '0'),
NULL,
'NO'
else
apex_item.text (3,(select language_name from foreign_language where x.language_id = foreign_language.language_id),
80,
100,
'style="width:170px" readonly="readonly"',
'f32_' || LPAD (ROWNUM, 4, '0')
end
|| err.language_id language_id,
/* apex_item.text(3,x.language_id,null, null, null, x.seq_id || '_language_id') || err.language_id language_id,
-- Employee Salary
apex_item.text(4,x.proficiency, null, null, null, x.seq_id || '_proficiency') || err.proficiency ||
-- Store the sql action type as well.
apex_item.hidden(50,x.sql_action_typ, null, x.seq_id || '_sql_action_typ_id') proficiency,
-- Last but not least the row error
err.row_error
FROM (SELECT ac.c001 seq_id,
ac.c002 ceah_people_id,
ac.c003 language_id,
ac.c004 proficiency,
ac.c049 modifiable_flag,
ac.c050 sql_action_typ

WHERE ac.collection_name = 'DATA_COLLECTION'
ORDER BY ac.seq_id) x,

FROM apex_collections ac
WHERE ac.collection_name = 'ERROR_COLLECTION'
ORDER BY ac.seq_id) err
WHERE x.seq_id = err.seq_id(+)

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,
x.ceah_people_id
from (
select apex_item.hidden(1,ceah_people_lang_id) ceah_people_lang_id,
apex_item.select_list_from_query(2,language_id,'select language_name, language_id from foreign_language') language_id,
apex_item.select_list_from_query(3,proficiency,'select name, id from proficiency') proficiency,
apex_item.hidden(4,ceah_people_id) ceah_people_id
from ceah_people_language where ceah_people_language.ceah_people_id = :P152_person_id
union all
select apex_item.hidden(1,null) ceah_people_lang_id,
apex_item.select_list_from_query(2,null,'select language_name, language_id from foreign_language') language_id,
apex_item.select_list_from_query(3,null,'select name, id from proficiency') proficiency,
apex_item.hidden(4,null) ceah_people_id
from dual) x
