Master/Detail Forms - How to go directly to detail?

The things you forget when you haven't used them in a while.
I have two tables:
MASTER with a MASTER_ID
DETAIL with a DETAIL_ID and MASTER_ID (foreign key back to master based on MASTER_ID)
When I generate the form using the wizard, how do I get the MASTER_ID on create so that I can immediately start adding the detail after creating the master (without having to go back to the report and select "Edit" (which works).
Basically, what I am asking is: How do I get the MASTER_ID sequence value(key) generated at INSERT populated in a form variable so that I can move straight to adding detail lines?
Thank you
--Too Sleep Deprived to think this through.

Both Seattle City Light (SPU) and the Seattle Police (where I work) are now using APEX. I actually love it as a development language (except for some of the page formatting issues which I deal with from time to time). We are "killing" all of our ACCESS 97 applications and moving them to APEX. But ACCESS applications for us seem to be like the Hydra - once I kill one, two more seem to appear in their place ("Oh, you did such a good job fixing our blah-blah database. Did you know about these other THREE...") Keeps me busy though.

Master Detail Form - How 2 update a field in the Detail form using a query?

Hello,
I have a master detail form with, each master record having a fixed(6) number of detail records. One of the fields in the detail record is the PART_DESCRIPTION field. I am trying to update this field by querying Table_X. TABLE_X is in the format of (desciption id, description). Description id runs from 1 to 6.
When the form displays, the PART_DESCRIPTION field for the 6 detail records needs to be automatically populated with the six values of description stored in Table_X. How can this be done?
Tried using session storage objects, but made no headway.
Would greatly appreciate pointers on how to go about doing this.
Thanks.
Dev

If you are on a Portal Version lesser than 3.0.9.8.3, then please try the following to populate
the PART_DESCRIPTION field.
Steps:-
1> Edit the form and go to the Additional PL/SQl section and put the following code in the
"...after displaying the page area" :-
declare
type t_vc_arr is table of varchar2(4000) index by binary_integer;
l_arr_desc t_vc_arr;
l_form_name varchar2(200);
l_form_state varchar2(500);
begin
l_form_name := p_session.get_module().get_name();
l_form_state := p_session.get_value_as_varchar2(
p_block_name => 'MASTER_BLOCK',
p_attribute_name => '_FORM_STATE'
if l_form_state = 'QUERY_AND_SAVE' then
select description
bulk collect into l_arr_desc
from <schema>.table_x;
htp.p('
<script>
var descArr = new Array();
var Fidx = 1;
var formObj = document.WWVM'||p_session.get_id()||';
var fieldName = "'||l_form_name||'.DETAIL_BLOCK.PART_DESCRIPTION.0";
for i in 1..l_arr_desc.count loop
htp.p('descArr['||to_char(i-1)||']="'||l_arr_desc(i)||'";');
end loop;
htp.p('
for (var i=0; i < formObj.length; i++){
if (formObj.elements.name == fieldName+Fidx){
formObj.elements[i].value = descArr[Fidx-1];
++Fidx;
htp.p('</script>');
end if;
end;

Portal Master-detail form how to auto assign detail record sequence number

Portal Master-detail form how to auto assign detail record sequence number.Please help me?

You can just read the following section
Can I specify a sequence number generator as the default value for a form column?
Yes. Enter the following in the "default value" field for the column:
#<schema name>.<sequence name>.nextval
where <schema name> is the name of the schema containing the sequence, and <sequence name> is the name of the sequence. The entry is preceded by a "#".
For example, if the schema name is "SCOTT", and the sequence name is "CUSTOMER_SEQ", the default value entry is:
#SCOTT.CUSTOMER_SEQ.NEXTVAL
same way you can do for master - detail form.
for more information on forms please refer the following URL.

hope it helps.

Master-Detail Form (How to pass an item value in Master to Detail field

I have a Master-Detail form. When adding a new record in the Detail section, I expect the primary key in the master record will copy down to the detail record. But, it is not doing that. Does anyone know how to pass the master primary key down to the detail record field.
By the way, query works fine. It knows the master-detail relationship. It is just when creating a new detail record, the key not pass down from the master record.
thanks - Patty

hi,you can do it by:in detail form's foreign key field,set it's default value as master primary key ,example master page p1,primary key as p1_master,detail form p2,foreign key p2_foreign, set p2_foreign key 's default value &p1_master.

How to determine the ROWNUM in a Master Detail Form

Hello,
I am working in a Master Detail Form with Orders and Order Items Information; and I created a process that allows the users to select a Product ID on a tabular form, and the next column is populated automatically with the Product Description.
To achieve that, I followed some instructions by Denes Kubicek (http://apex.oracle.com/pls/otn/f?p=31517:241), but my case is slightly different:
<ul>I am using a wizard-created tabular form, instead of a manual tabular form; and </ul>
<ul>Instead of using another page as a Popup to pass the parameter of the ROWNUM, I am using a plug-in called “Tabular Form Super LOV” which is a modified version of the SkillBuilders’ Super LOV that works on Tabular Forms. </ul>
The Product ID is returned in the correct row by the plug-in; but in the case of the Product Description, it is always returned into the first row; and my problem is that I don't know how to determine the row where the user clicked to call the plug-in.
I set up an example in apex.oracle.com in case someone would like to look at it:
Workspace: ediazjorge
Username: test
Password: test
App Name: Sample App
App Number: 1550
BTW, I am using Apex 4.1.1.00.23 and Oracle DB 10.3.2.
Thanks in advance,
Erick

Hello VC,
Thank you for your time and help.
Unfortunately, it is still not working properly:
1. When the Popup LOV opens, the first row of the tabular form is 0, the second row is 1, and so on. How can I assign the values starting with 1 and in the format *0001* ? (I am still a novice on Apex and new to JavaScript :-), sorry about that).
--2. Also, when I close the Popup LOV, the value of P1_ROWNUM is ‘undefined’ again so I'm not sure if the Product Name column will be populated.--
3. And finally, you are using the jQuery Selector uPopupLOVIcon, which is an attribute of the Cloudy Theme. In my real application (Apex 4.1.1.00.26), my element looks like: *<img src="/i/lov_16x16.gif" width="16" height="16" alt="Popup Lov" alt="List" style="vertical-align:middle;" align="middle" />*. What do you recommend me to use as a jQuery Selector?
Again, I really appreciate your help and time. I think you solved the most difficult part.
Thank you so much,
Erick
Update: I just found out that the problem with my comment 2 is because I didn’t delete the previous dynamic action that set the value to P1_ROWNUM.

How to set the Master Action of a master detail form?

Hi,
I have a regular form navigates to a master detail form in
insert mode. How do I make the MASTER_ACTION show up
as "Insert" instead of "None"? If I call the Master detail form
in auto query mode, it will show up as "Update" in the
MASTER_ACTION. How do I make the MASTER_ACTION show up as
"Insert" instead of "None"?
Any ideas are highly appreciated.
Thanks;
Kelly.

Just have a look over these two statements if it solves your problem
one time where clause
Set_Block_Property('BLOCK_NAME',ONETIME_WHERE,your form item);
dynamic where clause
set_block_property('BLOCK_NAME'default_where, your form itme)
you can where clause at run time from any procedure or some triggers

Hi Law,
Text in a shape or a text box will not feature in the table of contents.
To get a colour behind your titles, type them into your document (not a shape). Format as Heading or some other paragraph style the TOC will recognise.
Select the title text and Format Panel > Text > Font > Gearwheel > Advanced Options.
Choose Character Fill Color and choose a colour from the palette (left) or colour circle (right).
Example Titles (all on the same page for a smaller screen shot).
Chapter 3 (in a coloured Text Box or Shape) does not appear in the TOC:
Hint for cheats :
To give the titles a wider Character Fill Colour, add some Tab characters before and after.
Regards,
Ian.

Hi All,

Hi James,
I think that Mike is suggesting that you create a SQL View over the table and join together the individual primary key values into a single, unique, pseudo primary key. You can still include the individual columns in the SQL but you can then use this new column as the primary key on a form. However, you would also need to create INSTEAD OF triggers to handle inserts/updates/deletes as SQL will not allow you to update tables through a view. (See: [http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28370/create_trigger.htm#i2064426] for the Oracle details on this or Re: How to update view resp. table for an example within Apex).
Ideally, though, you should only really need one key column - is there any need for four?

How to display more rows in Master-detail form

I am working on APEX3.2.
I have a master-detail form. The detail form always display 15 rows. However, my customer wants the detail display all the rows. I tries to configure the Number of Rows in the report. It doesn't work. How do I do it?
Thanks a lot!

Hi:
To increase number of rows displayed you have to set Number of Rows and pay attention to both Number of Rows (Item) and Maximum Row Count.
After that if didn't work, sign out or close the browser then open it again. Sometimes it keeps the value in current session.
Saad,

Hi Chan Kelwin
I tried with ur code. But in the form loading first time the form controls are not cleared
i write the code in my page load. I take the query from view object runtime. it also
working fine but that is not reflected on the form. i used to drag and drop the detail view
and used to master-detail option for binding in the form. But still i have the same problem
i used the following code
@PostConstruct
protected void OnLoad() {
if (!isPostback()) {
// CreateNewRecord();
FacesContext fctx = FacesContext.getCurrentInstance();
ValueBinding vb =
fctx.getApplication().createValueBinding("#{bindings.TestCaseNewVOIterator}");
DCIteratorBinding userView = (DCIteratorBinding)vb.getValue(fctx);
String amDef = "model.masters.MastersAM";
String config = "MastersAMLocal";
ApplicationModule am = null;
am = Configuration.createRootApplicationModule(amDef, config);
ViewObject vo = am.findViewObject("TestCaseNewVO");
ViewCriteria vc = vo.createViewCriteria();
ViewCriteriaRow vcr = vc.createViewCriteriaRow();
vcr.setAttribute("Tid", "IS NULL");
vc.add(vcr);
vo.applyViewCriteria(vc);
System.out.println(vo.getQuery());
vo.executeQuery();
}

How to turn a table-based form into a master/detail ?

Hello, I have a form based on a table on which I have spent quite a bit of time adjusting presentation and adding dynamic actions.
Now comes the requirement to handle an open number of related records, ideally on the same page.
Has someone documented the steps needed to turn a record-based form into a master/detail one ?
I am using APEX 4..2.1

If you think your are missing something you could create the master detail pages for comparison. And delete these dummy pages when your done.
I finally got around to working on this. You got me on the right track Nicolette, so thank you for that.
I also had to fix bits in making processes conditional, and branching, too.
Mainly this has to do with the "delete checked" button which deletes detail records, and submits the page to itself.
One also needs to rename the REQUEST used in that case from MUTLI_ROW_DELETE to APPLY_CHANGES_MRD
(as this pattern will trigger an UPDATE for the master record)
All in all doable but one needs to be careful and generating a quick example M/D page for reference is useful.
In my case I reckon this was still faster than re-doing all the layout adjustments and DA's
(plus I got to better understand how this all works - there are a couple moving parts, all interdependent)
