Detect changes on tabular form

HI guys!
Is there any way to detect that there were some changes made on tabular form? My Client wants me to create items which are conditional upon changes made on tabular form. IE button X is only visible if there were no changes made on tabular form.
With regards,
PsmakR

Hello Konrad,
>> Stronger should be hiding button because there are changed cells …
OK. This is the simpler scenario.
The button should be rendered upon loading the page, as at this point there are no changes to the form.
You should leave the checkbox column, which selects your rows, unchanged (event free), as it doesn’t affect the visibility status of the button – it should remain visible even if rows were selected (without changing any other cells).
As I suggested in my first post, you should use the onchange event with all the other editable columns. The event should call a JavaScript function that hides the button, because when fired it means something has changed in one of the cells.

Arie.

Detect changed fileds in form

Hi all,
I want to build a "history" function in my Apex appliaction.
My idea is to record all changes in a existing record, in a new table, but I'm having some trouble to find the best way to do this.
I figured it out this way: After the user edit the record and submit the form, ONLY the changed fields will be recorded to the new history table. The fields that had no changes, will be ignored.
My problem is: how to identify the changed fields? Maybe create a function that will compare all fields, one-by-one, with the existing one and detect the changed one, but doesn't look like a very efficient way.
Does anyone have a better solution? Anyone already did something like that?
Thanks!

Using a trigger, that will loop through and determine what columns have changed (comparing :old. and :new.). How are you going to do this? One row per changed item is how I normally have seen it (Old Value: XX) in one column and (New Value in another)..
Thank you,

Changing tabular form column to checkbox

I have a tabular form in 3.2. There is a column that is a text field, but really should be a checkbox. I have tried changing the region source to something like, select a, b, APEX_ITEM.CHECKBOX(3, PRIMARY FLAG) "PRIMARY_FLAG", d
from my_table
WHERE a = :P52_XPROD, but the column still shows up as a text field, displaying a value like "<input type="checkbox" name="...etc.
Is it possible to change a tabular form column to a checkbox in 3.2?

edit your report attributes, then edit your column and change "display as" to "standard report column"
Thanks
Tauceef

Possible define changed at least one importance in tabular form?

There is example of the code?

Sorry, Iâm having difficulties figuring out what it is youâre trying to do. Are you asking if it is possible to change a tabular form? If so, the answer is yes, when editing your page, you can click on the report link and start editing your tabular form definition.

A default value in tabular form

Hi all,
I have a simple tabular form, and i'd like that if a certain field doesn't contain any value to fill it with a default value.
I tried to do it via default value attribute, but i'd like it to take place in a certain record in the table and not in all the records (which i can identify by a key, e.g. id)
how would you do it????
Liron

Hello Liron,
>> when i submit the page, it doesn't take the default value (which indeed appear on screen) but null
Well, if this default value is the only “change” in this row, it will not be updated into the table, because the tabular form mechanism is not detecting any changes in this row – remember, as far as the tabular form goes, this is the original value of the cell.
However, it seems like you want this default value to be saved, regardless of other possible activities of the tabular form. In this case, you should run the update prior to rendering the tabular form. You can use a before header PL/SQL block to do that. Using the EMP example, you can use a similar code in your pl/sql block:
update emp
set comm = 10
where comm is null and deptno=20This pl/sql block will run prior to your tabular form query, and all the updates will be reflected in the rendered result. Now you can continue to work with the tabular form to enter the rest of the changes you need (including deleting the new default values).
Don’t forget to change the tabular form query back to its original form. If you are using this technique, you don’t need the CASE statement.

Apex Collection- Tabular Form

Hi
is there anyway to make a tabular form depends on apex collections, for example i have a collection named "Orders" and i want to add member to this collection by tabular form , is it possible?
Thanks in advance

Sure, build a manual tabular form
SELECT APEX_ITEM.TEXT(1,AC.c001)
,APEX_ITEM.TEXTAREA(1,AC.c002)
FROM apex_collections AC
WHERE collection_name = <collection name>I can also think of an approach to get this working with a Wizard based tabular form(I haven't tried this before,but I don't see any reason why it shouldn't work).
--Create a view referring the collection.
--Change your tabular form to reference the view
--Add insert,update and delete triggers on the view to handle those processes on the appropriate table(s).

Tabular Form - new row at top not working

I'm trying to add a new row to the top of a tabular form (not manual) vs the bottom using Denes example - http://apex.oracle.com/pls/otn/f?p=31517:215 but it's not working. I absolutely need the records to sort on the date and time, but when I add a hidden column and sort it in descending order, then sort the date and time both in descending order, it doesn't sort correctly. I tried using the primary key field of the table as the hidden column, sorting nulls first, but the new record opens at the bottom (If I have "sorting nulls first" selected and at the time a new row is added the primary key field is null, why doesn't the new row open at the top?). I added a new field (date field with timestamp) to the query, then deselected "show" in the column attributes...that didn't work. I then selected "show", and changed the tabular form element display as to "Hidden", but then I got an error when I clicked "Add New", and I also added a column to my query via apex_item.hidden but no luck there either. What's the best way to go about this, but still maintain the date and time sort?
Thank you,
Tammy

We did that. It didn't resolve it...
Also, I compared the images directory from the complete apex 4.1.1. installation and compared it to patch 13331096 (latest 4.1.1 patch). They are identical.
Any other ideas I can try out?

Dynamic Action On change tabular form question

Hi guys!
I've wanted to add dynamic action on change (tabular form) to execute PL/SQL which checks if column of the tabular form has changed and if yes it changes walue of text field to Y or N. It doesnt work...and I don't know why. If I create validation with this PL/SQL it works. Can you help?
DA:
On change - Tabular Form
PL/SQL;
DECLARE
 nazwa VARCHAR2(4000);
 counter NUMBER := 0;
BEGIN
 FOR i IN 1 .. apex_application.g_f08.COUNT
 LOOP
 SELECT NAZWISKO INTO nazwa FROM SPR_META.M_UZYTKOWNICY WHERE NAZWA_UZYTKOWNIKA = apex_application.g_f02(i);
 IF wwv_flow_item.md5(nazwa) <> wwv_flow_item.md5(apex_application.g_f08(i)) THEN
 counter := counter + 1;
 END IF;
 END LOOP;
 IF counter > 0 THEN
 :P5_IS_TABULAR_FORM_CHANGED := 'Y';
 ELSE
 :P5_IS_TABULAR_FORM_CHANGED := 'N';
END IF;
END;Page items to submit: P5_IS_TABULAR_FORM_CHANGE
What's wrong?
With regards,
PsmakR

Region static id shouldn be in bracketsYou missed the '#' informt of the region id.
why my original PL/SQL process did not work
FOR i IN 1 .. apex_application.g_f08.COUNTThis works only when the application array has values and that happens only when the page is submitted.When you submit the dynamic action , it isn't.
This script combined with script to detect changes makes apex page running very slowIf you use that PLSQL code(assuming it works as expected) , then its going to take a server request every-time you change a field in the tabular form and loop though all the array values(if they would be submitted before) and recalculate and compare the checksums . Isn't that going to be very inefficient.
As for that JS code, it only runs at the client side. You can do all the server side checks on submit, when the user expects some delay due to processing.

ORA-06502 on "Help Text" region when changing pages on a tabular form

Hello everybody,
We are developing an application on Apex 4.1.0.00.32. This application have some pages with tabular forms and these pages uses a page zero as template. In this page zero, we have added two sidebar regions: a list region to navigate on the application and a help text to describe how to use our application.
The problem occurs when the tabular split the records into pages (since it has more records that it can show on a single page). When the user clicks to change to another page, Apex raises an ORA-06502: PL/SQL: numeric or value error as described below:

We have tried to change the pagination style of the tabular form and change the region model of the help text but the problem still happens.
Does anyone an ideia about what this may be?

How to dynamically change the column in tabular form

Hi!
Is there any way to show notice in tabular form if value entered is not in some range?
eg. I click on button add row, and then I fill out values and if one value is not within a certain range then in last column (this column is not included in table) is notice out of range or something else. I know that this can be achieved with validations but this must be just notice, not some restriction. Values I wrote must be inserted into table.
I hope you understand me. I use Apex 4.1 and 11g Oracle database.
Regards,
drama9346

Sure you can. If you edit your page attributes you have a field javascript on load. Here you can enter code that does checks or actions depending of user events. Example in the case of a tabular form:
$('input[name=f01]').live('change', function(){
if($(this).val()=='1'){
alert('value is 1');}
This will give an alert if you change the item in the first column to 1.

I am working with a tabular form to create an attendance sheet for a school using Oracle Application Express 3.0.1.00.12. Whenever I change the Number of Rows value from 10 to 1000 in the Layout and Pagination section of the report page, the SUBMIT button is not working and it is unable to process at that stage. How can I change the valu so that I can see all the rows in a single page, make changes to all rows and submit the page rightaway. Please help me.

Dynamic Action on tabular form: to auto set value for all changes rows

Hi All:
I am using APEX4.2.3 and I am not very familar with JQUERY or Javascript.
I am having a tabular form to support Update and Delete action. The tabular form has 4 columns:
Column A: ID                      (Number)     : Read-only column
column B: Name                 (Varchar2)   : Editable
Column C: Age                    (Number)     : Editable
Column D: ChangeFlag      (Varchar2)   : Read-only column                             ==> however, I want this column been automatically upldated by my APEX application
Here is the requirement: First user update Column B, or C or both for # of rows; then user click "Save Change" button. For ALL updated rows, I need to automatically update Column D with below logic:
For a given row,
               IF Column D IS NULL THEN
                     set value = 'M'                           -- M means modified
               ELSE --- column D has a value already
                    IF last character of Column D is 'M', THEN
                           don't do anything;
                    ELSE
                          set value of D = existing value + 'M'                       (here + means concatenate
                   END IF;
            END IF;
I thought this can be done by creating dynamic action on tabular form ... I have researched this on this forum and can't find a good match example ..
I know I can implement this using a DB trigger; however, I want to learn if this can be achived via Dynamic Action.
Thanks!

Using md5 in a manul tabular form to compare if column value changed

Version: Application Express 3.2.0.00.27

                              delremovalcomments, delegator)It doesn't seem to like where I attempt to convert date column delexpiry and datedelremoved to a varchar. I am doing this as in the db they are dates and inorder to using the md5 function to compare if the values have changed and only update rows where the values changed.
There error that I get is:
ORA-20104: create_collection_from_query Error:ORA-20104: create_collection_from_query ParseErr:ORA-00907: missing right parenthesis
In the collection I am trying to store the md5 hash result. I haved all the update and insert logic working expect for date type columns. THose give the above error.
I thank you ahead of time for your assistance!

Helen,
Not sure I fully understand your goal. We don't use "tasks" at all but if you are looking to have your workflow check certain valus and be able to send email messages to people based on whatever, then you can certainly do that (as long as your Sharepoint
has the email setup. We do this for alot of workflow tasks.
So, in the workflow you can have a blanket statement like what I previously listed:
if Current Item:hiddenStatus not equals Current Item:Status
    .... do something
or you can do something like:
if Current Item:hiddenStatus equals "In-Progress"
    .... do something
Else if Current Item:hiddenStatus equals "Completed"
    .... do something
or combine the two and do nested "if" statements. Then you add an email statement wherever you need it like:
if Current Item:hiddenStatus equals "Completed"
   then email "these users"
To add the email part, just type in "email" on the line where you want to add a statment. There is only one option to choose from. That will display the line "then email these users".   The "these users" will be a link. When you
click it you will get a popup to add the email info. We typically will send the email to a user (or users) that are already listed in one of the PeoplePicker fields. On the email form, you can type in your own text, designate that a value is based
on a column value (like our PeoplePicker), designate that a value is based on a workflow variable, add a link to the current item, etc. To get to these options you will click the button to the right of the fields or use the "Add or Change Lookup" button
in the bottom-left for the text area. There is alot you can set in the mail.
Does this help answer your question?

Tabular Forms - how to change the color of text when the field is disabled

Hi,
I have a tabular form and some of it's columns are disabled showing text in grey color...
is there a way to change the color to black and bold the text...?
thanks

Okay, i've taken a look at your example.
The column formatting does not work on the input fields. The help on the item says that it generates a span with a style attribute. This would work for a display field, not for an input field.
Css like i've written should be in the style tags, put up in the header section of the page (page -> edit -> header region).
You've already put script tags there, the style tags go there aswell. You shouldn't even need to put your script tags in the header region. Just put your code up in the javascript functions region (without the script tags).
However, i tested in firefox and here color works on an input field, changing the font color. In IE it does not do this. Cross browser implementations and such, not much to do about it here. See http://stackoverflow.com/questions/602070/changing-font-colour-in-textboxes-in-ie-which-are-disabled.
I did notice that you build your form with a bunch of input fields, which you disable through javascript in the footer of the region. Then on submit, you set the disabled to false again for all those fields! If you want those fields to always be submitted to the server, why wouldn't you use the readonly attribute? Readonly fields are always submitted, and can't be edited by the user. Plus, readonly fields CAN be styled however you want! You can get rid of the javascript code in your header then.
Even the javascript in the footer is not necessary. If you just add 'readonly="true"' (without single quotes) to the element attributes of your items (edit column -> column attributes region) = no javascript at all (less maintenance).
