No Data returned for tabular form APEX 4

Hi,
I have a page that uses a tabular form, however it is not showing me any data. If I click the add row button and enter some details and press submit, the data is saved to the database but the page is refreshed and still shows me no data. I don't however get a No Data Found message.
If I create a region on the same page based on a sql report, that returns the data I have added through the tabular form.
Any ideas
Cheers
Paul

My previous post appears to be incorrect as neither pages are now returning data!!!!
So I started again and this is what I have done.
1) Run the page and get no data. The SQL statement on the page is
select
"ID",
"ID" ID_DISPLAY,
"REFERRAL_ID",
"REASON",
"CREATED_BY",
"CREATED_ON",
"UPDATED_BY",
"UPDATED_ON"
from "#OWNER#"."REFERRAL_REASON"
where referral_id = :P82_REFERRAL_ID
2) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (12 in this case)
3) Traced the page and looked at the trace file which has the following statement
select NULL "CHECK$01",
NULL "ID",
NULL "ID_DISPLAY",
to_number(123) "REFERRAL_ID",
NULL "REASON",
NULL "CREATED_BY",
NULL "CREATED_ON",
NULL "UPDATED_BY",
NULL "UPDATED_ON",
NULL "ROWID"
from dual
union all
select "CHECK$01" "CHECK$01",
"ID" "ID",
"ID_DISPLAY" "ID_DISPLAY",
"REFERRAL_ID" "REFERRAL_ID",
"REASON" "REASON",
"CREATED_BY" "CREATED_BY",
"CREATED_ON" "CREATED_ON",
"UPDATED_BY" "UPDATED_BY",
"UPDATED_ON" "UPDATED_ON",
"ROWID" "ROWID"
from (select NULL "CHECK$01",
"ID" "ID",
"ID_DISPLAY" "ID_DISPLAY",
"REFERRAL_ID" "REFERRAL_ID",
"REASON" "REASON",
"CREATED_BY" "CREATED_BY",
"CREATED_ON" "CREATED_ON",
"UPDATED_BY" "UPDATED_BY",
"UPDATED_ON" "UPDATED_ON",
"ROWID" "ROWID"
from (select "ID",
"ID" ID_DISPLAY,
"REFERRAL_ID",
"REASON",
"CREATED_BY",
"CREATED_ON",
"UPDATED_BY",
"UPDATED_ON"
from "IMPULSE"."REFERRAL_REASON") apex$_rpt_src
order by 1)
call count cpu elapsed disk query current rows
Parse 4 0.00 0.00 0 0 0 0
Execute 4 0.00 0.00 0 0 0 0
Fetch 16 0.00 0.00 0 24 0 12
total 24 0.00 0.00 0 24 0 12
4) Amended the page to remove the where clause
5) Amended the page to removed the process that adds 5 empty rows
6) Run the page and still get no rows
7) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (12 in this case)
8) Log out of application and log back in
9) Run the page and get 500 rows
10) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (500 in this case)
11) Added the where clause back in to the SQL statement and rerun the page and get the correct numer of rows (12 in this case)
12) Log out of application and log back in
13) Run the page and get no rows!!!!!!!
14) Checked the wwv_flow_activity_log and can see that the number of rows returned is correct (12 in this case)
So I can only conclude that whilst the data is being retrieved from the database it is not being displayed on the screen. So what would be stopping the data from being displayed?

What's the deal with 'no data found in tabular form' in apex 4.1

We recently upgraded to 4.1 to resolve some of the issue found in 4.0. I have a form that populates a collection....it had previously worked in earlier versions and now I receive the following error when I try and SAVE.
any thoughts?
Contact your application administrator.
no data found in tabular form

HI Joel, thanks for getting back to me.
We recently moved from apex 4.0 to 4.1. I have an application that makes use of collections. All was working in 4.0, but now I am having problems with 4.1. I would be happy to move place application in more convenient spot, but need specific instructions as I am not certain how to do that.
basically, I have a report region, FAVORITES based on a collection (source listed below):
SELECT apex_item.checkbox (1,seq_id, 'onclick="highlight_row(this,'
|| seq_id
||')"', NULL, ':', 'f01_'
|| LPAD (seq_id, 4, '0') ) delete_checkbox,
apex_item.hidden(2,seq_id) seq_id,
apex_item.hidden(3,seq_id),
apex_item.text_from_LOV(c004,'SPECIES')SPECIES_ITIS,
apex_item.text_from_LOV(c005,'GRADE')GRADE,
apex_item.text_from_LOV(c006,'MARKETCODE') MARKET_CATEGORY,
apex_item.text_from_LOV_query(c007,'select unit_of_measure d, unit_of_measure r from species_qc') unit,
apex_item.text(8,c008,5) fav_order,
apex_item.select_list_from_lov
(9,
c009,
'DISPOSITIONS',
'style="width:200px;background-color:#FBEC5D; "',
'YES',
'0',
'- Select Disposition -',
'f09_' || LPAD (seq_id, 4, '0'),
NULL,
'NO'
) disposition_code
from apex_collections
where collection_name = 'C_DEALER_SPECIES_FAV' order by seq_id desc, c008
The collection appears and I am able to add rows to this collection. The problem is when I SAVE. The following is executed (and again, works fine in 4.0).
declare
dispositionCode varchar2(3);
begin
delete from frequent_species where permit_id = :G_permit_id;
for rec in (select c004,c005, c006, c007,c008,c009,:G_permit_id from apex_collections where collection_name = 'C_DEALER_SPECIES_FAV')
loop
if rec.c009 = '0' then
dispositionCode := null;
else
dispositionCode := rec.c009;
end if;
insert into FREQUENT_SPECIES (species_itis, grade_code, market_code, unit_measure, fav_order, disposition_code,permit_id) values(rec.c004,rec.c005, rec.c006, rec.c007,rec.c008,dispositionCode,:G_permit_id);
end loop;
exception when no_data_found then null;
end;
I receive the message:

Populate select list when a date selected from date picker in tabular form

Hi Guys,
I have a situation where user picks a date from a date picker in tabular form.
So as soon as he picks a date say 05/31/2011 from the date picker I want to populate a select list with 2 values : Tuesday AM , Tuesday PM.
I have gone through the forums a lot and figured we can write a Dynamic Action using JQuery Selector. But I am not sure how to figure out the day from a date picker.
I appreciate if some one can give your thoughts on how to proceed. It seems to be simple but looks like a tricky one. I am not familiar with writing Java Script.
Thanks ,
Raj

I was thinking your date selected from CALENDAR ended in a list_item.
I don't know I thinking that
well,
:master_block.itemdate is your text_item where calendar return date selected.
and then , following Gerd's step
Create a WHEN-MOUSE-DOUBLECLICK on the date-item of CALENDAR and write :
begin
:master_block.itemdate := calendar (.........);
go_block ('master-block');
execute_query;
end;
or set a global or parameter variable date selected from calendar :parameter. xxxxxx
in a PRE-QUERY
:master_block.itemdate := :parameter. xxxxxx
and
Create a WHEN-MOUSE-DOUBLECLICK on the date-item of CALENDAR and write :
begin
:parameter. xxxxxx := calendar( ....);
go_block ('master-block');
execute_query;
end;

HTML in SQL for tabular form

I am trying to use HTML directly in SQL statement for tabular form (see SQL below). When the tabular form runs it is not converting the HTML so it displays as this:
Manala<span style="color:blue;">pan</span>
Am I missing something?
select
"PK_ID",
"CODE",
decode(instr(upper(city_name),upper(:P3_SEARCH)),
0, city_name,
substr(city_name,1,
instr(upper(city_name),upper(:P3_SEARCH)) - 1)
|| '<span style="color:blue;">' ||
substr(city_name, instr(upper(city_name),upper(:P3_SEARCH)),
length (:P3_SEARCH))
|| '</span>' ||
substr(city_name, instr(upper(city_name),upper(:P3_SEARCH)) + length(:P3_SEARCH) )) "CITY_NAME",
"STATE_CODE"
from "#OWNER#"."ZIP"
where upper(city_name) like '%' || upper(:P3_SEARCH) || '%'

Right. The HTML is correct but the only way it will display right is when I changed the field attribute to 'Standard Report Column'. Unfortunately, that removes the field from being a text field (input).

Multi Row Update for Tabular Form

1) I'm trying to understand how the built-in MRU works for tabular forms: While running through every row, does it check for changes before issuing an UPDATE or does it blindly UPDATE every row in the current pagination range?
2) If I need to write my own Multi Row Update process for tabular forms, could someone give me some tips on how to do that?
Thanks,
Pavel

1) It stored a checksum for each row that it renders. It calculates the checksum again before processing the rows. The UPDATE statement it issues has a predicate like where old_checksum!=new_checksumSo, it only updates the rows that have at least 1 column value that is different (causing the row checksum to be different)
2) See the howto at http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html

You do not have permissions to access a database that contains data required for this form to function correctly.

I have dropdown on infopath form , and it receives data from sql server table , it works fine when i am running in preview mode , but when i am publishing form to sharepoint server and loading that form
i am getting this
You do not have permissions to access a database that contains data required for this form to function correctly.
Can you please help?
Thanks,

try this one, if not yet
Convert the data connection to UDC (store it in a Data Connection Library within the same site collection as the form library). See if this works without any other changes, but if not, then...
Manually edit your UDC file in Notepad (or your preferred editor) so that the authentication line is not commented out and so that it references the name of the SSO target app you created.
For Type, use NTLM.
Ensure the user has rights to access the database
Also ensure the connection file has been approved - A sharepoint admin can access a non approved Ucdx file. Go to the connection library and approve the file

and i have stored the connection file into the connection library and i have approved.
The form working fine in server (browser), but whenever i m trying to open the form in client browser i m getting the below error.
please assist me to resolve this error.
venkateshrajan

Hi,
Please make sure following options are enabled in Central Administration > General Application
Settings > InfoPath Forms Service > Configure InfoPath Forms Services.
1) Allow user form templates to use authentication information contained in data connection files.
2) Allow cross-domain data access form user form templates that use connection settings in a data connection file.
(-This you have done)
Do you use host name to access the data source? If yes, please
check of the DisableLoopback check is enabled. Please make sure the loopback check is disabled on all SharePoint servers and reboot server to test if it works.

Validate field in tabular forms apex 4.2

Hi.
i need help doing next validations :
1.- i have a product_item field (wich is a lov and user choose one value), so i need to call a function (sending it the selected value product_item) that will return me some data about the product i selected, for example :
if the function return 'A' then
disable the next item on tabular form, lets say quantity
else
enable the next item on tabular form, lets say quantity
end if
2.- i need to determine the result of two items operations:
total := final_quantity - start_quantity
the user will introduce start and final quantity and i will determine the total.
any ideas ?
i am new on apex and need to do this on tabular forms.
thanks in advance.

Thomas,
Is this a standard APEX tabular form validation, or a custom PL/SQL based validation? It might be easiest to diagnose what's going on there, if you could replicate this issue on apex.oracle.com, and point us to an example.
Thanks,

How to display dates dynamically in tabular form title

Hi,
I have a requirement of displaying dates of the week as title of each column heading in the tabular form dynamically (or) Is there a way to display the dates for each week as the titles for each column dynamically?Could anyone suggest me on this requirement?
Thanks & Regards,
Balaji.P.K.

Hi Balaji,
if you want to be very generic than create a report based on a "PL/SQL Function returning SQL Query" and set the Report Column Headers to "PL/SQL" and specifiy a function returning the Header Titles.

Insert a number of rows for tabular form based on frequency value

Hi,
I have a page with two search items.
Based on the values in the search item, a report is created as tabular form.
The information displayed has a frequency column.
Values for frequency can be Q, Y, M, D
I would like to know if it is possible to to load the form with a standard numbers of row depending on the frequency.
Example: If frequency is Q ,then when i click the go button in the search region, the tabular shoud load with the information displaying 4 rows, even if the information returned is less than 4 rows.
If frequency is Y ,then when i click the go button in the search region, the tabular shoud load with the information displaying 2 rows, even if the information returned is less than 2 rows.
When no data is found, the form should load displaying a number of empty rows depending on the frequency.
Thanks

Hi,
I have two date columns in a tabular form
1.Start_date 2.End_date so here i need to validate the end_date as should not be lesser value than start_date column

IF to_date(:YOUR_END_DATE,'YYYY-MM-DD') < to_date(:YOUR_START_DATE,'YYYY-MM-DD') THEN RETURN FALSE;
ELSE RETURN TRUE;
END IF;The date format is of course in your choice.

Hi User XY,
tabular forms do not have Page Items. The values you entered in the tabular form are stored in arrays like APEX_APPLICATION.g_f01 to g_f50.
Here are some links you might find helpful: http://www.talkapex.com/2008/07/manually-creating-tabular-form.html
