Apex_Item.radiogroup in a Tabular Form (Update Only, no Insert)

Hi,
I'd like to use a radiogroup on a tabular Form. The Form will modify only existing records.
I've seen some more elaborate examples for Tab Forms that allow Insert.
But I am trying to use the APEX_Item.radiogroup function for an example like:
"Select Chairperson_Name, Approve_Status FROM Chairperson_Approval"
The Approve_Status column can be 'A' for Accept, or 'R' for Reject, and is the only updateable column in the Tabular Form.
So I should be able to create a Tabular Form (for Update Only) on the table Chairperson_Approval with the wizard.
Then I want to be able to go into the Source and change the SELECT statement to something like:
"Select Chairperson_Name, APEX_Item.radiogroup(1,approve_status,.....) FROM Chairperson_Approval"
and then let the automatic APEX processing (generated by the wizard) do the rest. Right? Can
anybody give me an exact example for APEX_Item.radiogroup. My documentation is not clear enough on this function.
Thank you very much, in advance.
Carol

Hi Andy,
Why do you get & set TEST attribute of the radiobutton?
What is a TEST attribute?
getAttribute("TEST") == 'Y')
setAttribute("TEST","Y");So I was thinking I should incorporate this toggle me function with my radiobutton and have the following inside the toggleMe function.
$x(''P24_SECONDARY_TASK'').value=' || ad.task_id || '"')
{code}
Am I right?
Cheers

Once more - tabular form / update only rows that have changed

I know it's been asked before, but I haven't seen an answer I like. :-)
I have a query that includes a single column the user can update, using APEX_ITEM.TEXT(10, updateable_field, 10, 10)
I have an additional APEX_ITEM.HIDDEN(21) and APEX_ITEM.HIDDEN(22) that hold the two fields of the composite primary key. In order to track whether my updateable_field had changed, I created APEX_ITEM.HIDDEN(11, updateable_field), which I expected would hold the OLD value of the field. See where I'm going with this? :-)
I'm attempting to loop through apex_application.g_f21, get the values for F10 (new) and F11 (old) and compare them. If they're different, I'll do the update.
It works fine if the old value (F11) is empty and I plug in a new value (to F10).
But if I change a field that had already has a value (in F11) and make it NULL, I notice that F11(i) doesn't exist. In that case, I set the value to NULL, and the compare fails because it thinks the row is unchanged.
Can someone suggest or point me to an alternate method that works?
Thanks as always,
Stew

Mike,
Thanks for the suggestion, which is a good one. But I had that one covered.
I have it working now, and I believe the fix was that I moved the APEX_ITEM.HIDDEN that contained the old value in the query. I'd had it concatenated with the column for the new value (which used APEX_ITEM.ITEM). I changed it to concatenate to a plain string value. And now the array has values in it, which I can properly compare.
Thanks again. That was really driving me nuts!

Tabular Form - Read only condition for certain users

Is it possible to make a select list field in a tabular form read-only to certain users? Here's the situation:
The tabular form lists the users who need to select "Approve" or "Reject" in that field (they are approving or rejecting an engineering change)
I want all of them to see the approval/rejection of their team, but only have access to edit the select list associated with their record.
Thanks in advance.

You could use either "authorisations" tab or "conditional display" for the relevant column attribute.
Report Attributes->Column Attributes->authorisationsIt would be better to have some more detail about what you are trying to get (maybe a quick mock up of the form, for example) but, I can envision something along the lines of the following:
For each approval/rejection field:
1. Create an authorisation appropriate for access to to each approval/rejection field e.g. authorisation scheme "FOO"
2. In the relevant fields column attributes, set the authorisation to "FOO"
3. now create a read only "public" copy of the above field, using the "display as text (based on LOV does not save state)" - set the authorisation for this field as "{NOT FOO}"
(if you don't want to use authorisations, you could build an equivalent using "conditional display" instead, which is basically the same thing, except column specific)
The downside is of course that you're duplicating fields in your query, which creates a bit of redundancy. There may be better ways to achieve this (maybe you could make use of the APEX_ITEM api, for example) but this is fairly easy to set up IMO.

APEX tabular form update recognition

Dear all,
I am quite new to APEX so please apologize if I am asking "stupid" questions. Unfortunately, the information I was able to find up to now was only partially helpful. Apparently I must be missing something obvious. The APEX version I use is 4.0.1.
When submitting a page that contains a tabular form, I need to find out, which record has been created or updated in order to fill in additional information automatically, e.g. logging data (created, last updated, ...). I cannot do this in a trigger, because the trigger sees only APEX_PUBLIC_USER and does not know about the "real" user who has connected to the database. If there is a better or easier way to do this, please let me know.
My problem is to find out, if a new record has been added by clicking the "add row" button and / or if an existing record has been modified, because creation and modification have to be handled differently. Existing and unmodified records in the table must not be touched. I can access the columns by using APEX_APPLICATION.G_Fxx() but how do I recognize modifications? In a thread in this forum I found information about using a MD5 checksum. So I have added a checksum field using APEX_ITEM.MD5_HIDDEN() and tried to check this information. Unfortunately, doing this, I already get a problem when I submit the page after having added an empty record by clicking on "add row" but without having supplied any information. APEX then complains about information that has been modified in the meantime instead of just ignoring the empty record. This is probably because APEX considers the record as changed because of the checksum column I have added (I have read that the SQL query to create the tabular form must not be altered).
Could anybody please show me the right way to do such a check?
Thank you very much for your help.
Best regards,
Ralf Gorholt

Hi Ralph,
Well, if you are wanting to check if anything has been updated before the update button is pressed, using JS, you can use the property of the field 'defaultValue' and compare it to the property 'value'
i.e. for the text input type
function isElementChanged( myElement ) {
var iselementChanged = false;
var returnVal = false;
switch ( myElement.type ) {
case "text" :
    if ( myElement.value != myElement.defaultValue )
      return true;
    break;
default
     return false;
} You could cycle through all elements, by:
allEls = form.elements;
for (i=0; i < allEls.length; i++){
if ( allEls.type != undefined && allEls[i].type.length > 0 && allEls[i].disabled == false ) {
if (isElementChanged(allElls[i])) {
//TODO: logic here

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

Tabular Form : Update column

Table - TIME_RECORD
Manual Tabular Form query

Please suggest why only date is displayed ? why Time is not displayed.

Implicit conversion of DATE to VARCHAR2 uses the NLS DATE FORMAT.

Tabular form Update Error,"Current version of data in database has changed

I'm getting an error when updating a Apex Tabular form. It's complaining that the row id's are out-of-sync. The error reads,' Current version of data in database has changed since user initiated update process. current row version identifier = "56DW5A8A7EBA3B42073AE6E71480A784" application row version identifier = "99B52A15F10E34647E9E18B6B7AE8C30" .
Has anyone received this error? Any solutions? Note that the primary is being populated by a trigger. I have another tabular form for a different application that updates without issue, this however, uses a sequence to update the primary key.
Thanks,
James

Make sure that the form is defined such that it "knows" that the PK is being set by a trigger. Do not try to set it in the form if the trigger is doing it. Pretty much if a trigger attempt to modify any column that also was editable (including hidden columns) in the form, the two will conflict.
The other issue could be that do you have any items on the rows that are disabled? Disabled items are not sent to session state so Apex won't be able to properly compute the checksum and it'll find a discrepancy.

Manual tabular form "Update Process"

Hello,
i made a tabular form manually,
now i want to add an update process, but its not working?
I created a Button "P_UPDATE" and i added a Process which listens to the P_UPDATE Button.
i used the following PL/SQL script:
for i in 1..htmldb_application.g_f01.count
loop
update MATCHUMSATZ
set PARTNER_ID = replace(htmldb_application.g_f10(i),'%'||'null%',NULL),
RECH_DATUM = replace(htmldb_application.g_f02(i),'%'||'null%',null),
RECH_NR= htmldb_application.g_f06(i),
PROV_GRUNDLAGE= htmldb_application.g_f08(i),
KUNDE= htmldb_application.g_f14(i),
VERTRIEBSART_ID = replace(htmldb_application.g_f17(i),'%'||'null%',NULL)
where id = htmldb_application.g_f01(i);
end loop;
This is an example which i customized from: http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html
I suppose that 'htmldb_application.g_f01' is the ID of the table 'MATCHUMSATZ'.
Why is there replace() and sometimes not ?
Would be glad if anybody could help me!
Phil

Hi Phil,
You can add in the in-built MRU update process that will do this for you. When you add a process, select Data Manipulation then Multi Row Update, then follow the prompts to link it to your table.
In your code snippet, htmldb_application.g_f01 refers to the first column in your form (even if this is hidden). Normally this is the Primary Key for the table on which the form is based. htmldb_application.g_f02 refers to the second column and so on, although you can assign any number from 1 to 50 to each field when you create the sql statement.
The replace() function is used because some of the fields will contain %null% which needs to be converted to null before updating the table.
Regards
Andy

Tabular Form Read Only Date Picker

Hello,
I have two or three Items with date pickers and do not want to implement
this code because it will be too many buttons on my form. I need to clear one item
at a time when the datepicker is readonly but, in a tabular form.
function f_clear_items()
    {$x('P1_ITEMA').value = ''};
    {$x('P1_ITEMB').value = ''};
    }Then once I create a url button and pass this function I can clear the datepicker's. But, I
was wondering is there a cleaner way to this.
I have other items on the page that are named the same but, in different tables. I only want
to clear each date picker item at a time. This code works fine for a regular form.
-Element Post Element Text for the Item to Clear
a href="javascript:setValue('P1_ITEMA','');">Clear Date</aThere is a thread named 'How to clear a read only page Item...?' that states how this code works but, does not
work for a tabular form in a Master Detail page. There is a link on side the Date Picker to clear item specified but, in a tabular form Item, there is no Element tab, any ideas on how to clear a readonly date picker item using a tabular form
and not using a button for each item, thanks in advance. I am using Application Express 3.2.0.00.27.

Dan,
I totally understand your point of view. So, this tabular form aspect was not tested once the Clear Date link was discovered to clear a Read Only date field. Yes, using a button to clear a date is great but, I do not want to clear every date or specified item with the click of one button for this application. It is very useful but, not for my needs at the moment.
Basically, if a date is selected and it needs to be cleared out you can just delete the value. But, if the date is readonly you can not clear/delete the date value unless you have the Clearing functionality for a particular item using the datepicker. It may not be worth the trouble Dan like you state by adding this extra code to the calender. If an invalid date is entered an error will appear anyway.
Thanks alot Dan for expanding my mind and showing me some JQuery and providing me with this link to do some further research if needed, thanks again.

Tabular Form update,delete

I am using database 11G, on windows XP with apex 3.0. I have created a tabular form with update & delete buttons. The table is a detail table having foreign key columns. On creation of form I choose foreign key column as primary key. The problem is when i check one row for delete the rows having same id on foreign key column are also deleted. Second When I update the following error is reported & no column is updated,
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "197D508D2444826DA98FC1E3D259EA31", item checksum = "F98E67DE7FF4EC9710E5A1B052E38C78"., update "HT"."INTRA_ORAL_EXAM" set "OPD#" = :b1, "TOOTH#" = :b2, "RESTORATION" = :b3, "DENETAL_DECAY" = :b4, "XRAY" = :b5, "SYMTOM" = :b6

Hi,
OK - that makes it a bit more complicated as you can not add a primary key to a table that contains data. This means that we will have to copy the data into a temporary table first.
Assume that you have a table called C_TABLE that is defined as:
CREATE TABLE C_TABLE
FIELD1 NUMBER,
FIELD2 NUMBER
)These are the steps that you need to do (each of these bits of code run be run separately):
Firstly, copy the data into a new table:
CREATE TABLE C_TABLE_COPY
AS
SELECT FIELD1, FIELD2
FROM C_TABLECheck that the table has been created:
SELECT * FROM C_TABLE_COPYThen drop the existing table:
DROP TABLE C_TABLECreate C_TABLE with a new Primary Key column:
CREATE TABLE C_TABLE
C_ID NUMBER,
FIELD1 NUMBER,
FIELD2 NUMBER,
CONSTRAINT "C_TABLE_PK" PRIMARY KEY (C_ID)
)Create a new SEQUENCE object to provide the primary key with values:
CREATE SEQUENCE "C_ID_SEQ" MINVALUE 1 MAXVALUE 99999999999999999999999 INCREMENT BY 1 START WITH 1 NOCACHE NOORDER NOCYCLECreate a new TRIGGER object to populate the primary keys with new SEQUENCE numbers when new records are added to C_TABLE:
CREATE OR REPLACE TRIGGER "C_TABLE_BI"
BEFORE
INSERT ON C_TABLE
FOR EACH ROW
DECLARE
v_id NUMBER;
BEGIN
BEGIN
    IF :NEW.C_ID IS NULL THEN
      SELECT C_ID_SEQ.nextval INTO v_id FROM dual;
      :NEW.C_ID := v_id;
    END IF;
END;
END;Enable the trigger:
ALTER TRIGGER "C_TABLE_BI" ENABLECopy the data back into the table:
INSERT INTO C_TABLE (FIELD1, FIELD2)
SELECT FIELD1, FIELD2
FROM C_TABLE_COPYCheck the new table has primary keys:
SELECT * FROM C_TABLEAndy

APEX - tabular form update

Hey guys,
as per client's request, we need to insert rows into db from tabular form even there is no change on the new row. db table is configured to have nullable fields.
Currently, it won't allow me to do so. Is there any way to force the insert/update without checking if the information on the row is updated?
Thanks a lot

You can do it, using manular tabular form.
When you use automated Tabular Forms, it checks inbuilt global variables, to see row is updated or any new row is created and all necessary fields are keyed in.
If you don't update an existing row, that row will not be updated..
If you create/add new empty row and don't key in values, that row will not be inserted as there is no data..
If you want to do in that manner, make your MRU process on the page to never and write your own manual MRU
