Updating columns in master/detail form

Changes were made to the database that is in the master part of a master/detail form. I have tried to add the new fields using "Create Item" on the page definition.
I have gone through the wizard and set the source items to:
Source Used: Always
Source Type: Database Column
Session State: per session
Source Value: AppsDependentOn (the name of the newly added field)
It seems that the form will not display the new column - it does display the label and a blank textfield. I have no problem adding columns to the detail part of the form.

"197331",
For Source Value, try uppercase instead: APPSDEPENDENTON

Hi cant see the primary key column in master detail form

I have a master detail form .In the first master form i am unable to see the primary key
Now the form is built completley and i also will like to see the primary key column visible in master report
If i had set the primary key as rowid then i could have seen the primary key ..
Now i can see the pencil icon (The eidt row pencil icon) instead of the actual primary key column . .which is a number data..
I will like that too be visible ..Can any one guide what should i do for this..
Thanks

Hi Mat,,
I am using apex 4.2 db version 11g and in the first master page i had set the value of combo which is primary key column as text
But still iam not able to see the number ..Note if i recreate the form ..with rowid as primary key i am able to see the column since the pencil icon(edit icon) is on row id..
Currently All i see is the edit icon ..I need both the edit icon and also the number ..
Thanks

Primary key updation in the Master details form.

Hi All,
I am struggling with Master Detail form in apex 3.12.
I have two tables.
SaleMaster ( TRN_ID as PK ) Created from Sequence.
SaleDetail ( TRN_ID , TRN_TYPE as PK) TRN_ID FK from SaleMaster , TRN Type is user Input in SaleDetail.
What is best simple way to create the master details form for the above master details tables.
Thanks.

I found a way. I dont like it - but it works.
I made a column link in the detail with the following:
javascript: doSubmit('NAVIGATE@#ROWNUM#);
This way I obtain information in the :REQUEST object about which row was clicked.
In a After submit process on the page I then parse this :REQUEST object like this:
DECLARE
v_row NUMBER;
v_pos NUMBER;
BEGIN
v_pos := instr(:REQUEST,'@',-1);
v_row := substr(:REQUEST, v_pos+1);
IF APEX_Application.g_f02(v_row) IS NOT NULL THEN
:P_PRIMARY_KEY_ID:= APEX_Application.g_f02(v_row);
ELSE
:P_PRIMARY_KEY_ID:= -1;
END IF;
END;
I know that my "Id" column is named f02 in the form, so this way I can find the id. I then assign this id to a kind of global variable - on the page I redirected to I can now find the Id.
Talk about ugly code :P

Master Detail Form - Update Statement for Column in the Detail Section

Hello,
I've posted a demo application to apex.oracle.com
Application# 49298
Application Name: Street_Inventory
Basically, on page 3 I have a Master Detail Form. In the Detail section, I want the value of On_hand to save to table ITEMS. Here's my code below.
SOURCE
select
"CONSUME_DETAIL"."CONSUME_DETAIL_ID",
"CONSUME_DETAIL"."CONSUME_HEADER_ID",
"CONSUME_DETAIL"."ITEM_ID",
"CONSUME_DETAIL"."CONSUMED_QUANTITY",
("ITEMS"."ON_HAND" - "CONSUME_DETAIL"."CONSUMED_QUANTITY") as "ON_HAND"
from "CONSUME_DETAIL",
"ITEMS"
where "CONSUME_HEADER_ID" = :P3_CONSUME_HEADER_ID
and "CONSUME_DETAIL"."ITEM_ID"="ITEMS"."ITEM_ID"
UPDATE INVENTORY PROCESS
UPDATE ITEMS
SET ON_HAND = :P3_ON_HAND - :P3_CONSUMED_QUANTITY
WHERE ITEM_ID = (select ITEM_ID
from CONSUME_DETAIL
where CONSUME_DETAIL_ID = :P3_CONSUME_DETAIL_ID);
My code isn't working. What am I doing wrong?

WReed,
The first thing I see "off the bat" is that you don't have items named P3_ON_HAND and P3_CONSUMED_QUANTITY which are referenced in your code. Although it's possible to do what you want with just SQL, I updated your code with a little PL/SQL to make it easier to understand...
As you'll see the problem now is that the design/db model is not quite right as your getting a too many rows error.

Master/detail form - Detail columns lack help information

I have a master/detail form. All the fields in the master block have help information attached to assist the user when entering data. The detail block, which is more of a multi-row based block, has column headings along the top. However, no where can I insert "help" text for these particular columns. Although self explanatory, it still would be nice to be able to incorporate "help" text for these columns. Am I missing something? Can this be done? I've thought about a button on top of the region which could call an html page with help for these columns, it just seems to be a "rougher" solution than whats available to the individual fields in the master block.

Hi,
Nope, you're not missing anything - there is no Help functionality. This is probably because the Help on page items is available for "Labels", which do not exist for tabular forms, which are based on a report structure.
You would, if you wanted, update the heading to include a "tooltip":
Instead of, for example:
HiredateYou could enter:
<span title="Enter the employee's hire date">Hiredate</span>It should also be possible to mimic the popups you get for page items if that is what you need

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;

Problem: trying to update all detail rows on pre-commit (MASTER DETAIL FORM

Hi:
I got a MASTER DETAIL form... and I need to update every detail row of this form (if the master was updated) before commiting the changes. the problem is that i cannot do that for instance in PRE-COMMIT or ON-COMMIT... it's an "illegal operation". I achieved part of it by coding KEY-COMMIT... but that did not solve the all problem. first take a look of the kind of code i want execute before commiting.
form trigger key-commit code is is somehow like this:
DECLARE
tot_line NUMBER (3);
line NUMBER (3);
begin
IF NAME_IN ('system.form_status') = 'CHANGED'
THEN
GO_BLOCK ('DETAIL');
LAST_RECORD;
tot_line := GET_BLOCK_PROPERTY ('DETAIL', current_record);
FIRST_RECORD;
line:= 1;
LOOP
:detail.quant := :detail.quant + 1;
EXIT WHEN line= tot_line;
next_record;
line:= line+ 1;
END LOOP;
FIRST_RECORD;
GO_BLOCK ('MASTER');
END IF;
COMMIT;
end;
The problem is for instance when the users close form in the "X" button (right top, near minimize form) ... If they do that Forms ask "Do you want to save changes?" ... and with this i do not execute the update of the detail rows...
But there are other situations when this happens... for instance if EXECUTE_QUERY when i change a record...
Anyone help?
Joao Oliveira

Use PRE-UPDATE trigger (Master block).
begin
update <detail_table>
set quant + 1
where <detail_table>.<relaition_column1> = :<Master_block>.<relaition_item1>
and <detail_table>.<relaition_columnN> = :<Master_block>.<relaition_itemN>
and <detail_block_WHERE>;

Master-Detail-Form; Hide/Show columns in detail form depending on column

Hi,
i have a master detail form. In the detail form i have the columns:
ID, MASTER_ID_FK, PC_SOURCE, A_C1, A_C2, A_C3, B_C1, B_C2, B_C3
The Column PC_SOURCE should be a LOV with values
NULL
A
B
So if i choose or enter a master record the detail form appears and i can enter one or more detail records.
PC_SOURCE is the first column.
If i choose A, the columns B_C1, B_C2, B_C3 should disappear as there should no entry possible.
If i chhose B, the columsn A_C1, A_C2, A_C3 should disappear as there should no entry possible.
Is that possible?
I tried a little on my own but without success. I tried to put into the first column (PC SOURCE lov) in Element Attributes a javascript call like onChange="do_Refresh('#PC_SOURCE#');"
The javascript funktion do_Refresh tries to catch the column value and set a hidden item P1_SOURCE like document.getElementById('P1_SOURCE').value = v_source;
But this does not work, as there is not the value of the column fetched.
And probably can´t work because of the more than one detail rows.
Thanks & regards,
Matthias

Hi,
The html for your detail form will be a table of input elements with names f01,f02,etc. The columns for the key fields are normally hidden so your PC_SOURCE column will probably use the name f03. The name for column A_C1 will be f04 etc.
Once you have the input names for your columns you can create a dynamic action (DA) to hide the elements you want.
You want the DA to fire when any PC_SOURCE element is changed so you want the when to be:
Event: Change
Selection Type: jQuery Selector
jQuery Selector: input[name="f03"]
Condition: no condition
The action is to hide an element in the same row if the changed element is a value. So the action should be:
Action: Execute JavaScript Code
Fire when Event is: true
Code: if(this.triggeringElement.value=="A"){$x_Hide('f04_'+this.triggeringElement.id.split('_')[1])}
You then need lots of true actions for each element you want to hide.

Master Detail Form with Report - Referring a column in another table

I have master detail form with a report option. The master table has a column that also references a look up table.
When the report is displayed the lookup column id is displayed. Rather I want to get the look-up value from a lookup table
and display in the report.
When I see the report region Query definition , it just has the columns to add/remove only from the master table.
Could you pls help me with this regard.
Eg :
Dept Table
dept_id
dept_name
location_id
Employee Table
employee_id
employee_name
dept_id
location
location_id_id
location_name
Master is Dept, Detail is dept and lookup table is location.

Simply add the lookup table to the FROM clause and join its PK with the FK in the master table in your query. That's basic SQL, and you definitely must get a good grasp of SQL to do more than very basic work in APEX.
For a good example, please see http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10498/build_app.htm#BCEBJJGB
While you're at it, read and implement the tasks outlined in the 2 Day + Application Express Developer's Guide - http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10498/toc.htm. After that, read the "Oracle Application Express 3.0-- Building a Functional Application" OBE in http://www.oracle.com/technology/obe/apex/obe30/apexdev30.htm - great stuff.

Limit on number of columns details of a master detail form/report

Hi,
I understand that there is a limit to the number of columns you can have in a master detail form/report. I am on Apex 4.01 and have a detail section that shows 24 months at a time as columns with integer hours assigned each month. My master detail was working fine with as many as 24 months/columns in this detail section, but I tried to re-use months by 'recycling' months, clearing them out of values and adding the months to the end of each row but now I am getting errors even though I had more columns showing before my 'recycliing' of the columns. The error is:
"ORA-06502: PL/SQL: numeric or value error: character string buffer too small "
What I don't understand is -- why am I getting this error now when I actually had more columns in the detail section months ago, and all I am doing is 'recycling' prior columns back into the detail report, not actually adding columns.
Thanks for any insights anyone can give.
Pat

DBA tells me that we are at 9.0.2.2.14, (higher version than the one you suggested) but I still get the same error.
Thanks,

How to create Insert & Update on master-detail form JPA/EJB 3.0

Is there any demonstration or tips how to Insert record on master-details form for JPA/EJB 3.0 with ADF binding?

I have master-detail forms (dept-emp). I drag the dept->operations->create method to JSF page. But when I click create button, only dept form is clear and ready for insert. But emp form is not clear. How can I add create method for this?
Can you give some example how to pass the right object to the persist or merge method so that it can save both the two objects (master-detail tables)
Thanks

Master Details form (LOV based on Detail Column of Join Condition)

I have created a master detail form where user_id is joining master and details.
I have created one dynamic lov based on child user_id in detail block to diplay all user who works under current user.
Problem : When i want to select Insert detail action in detail block the dynamic lov should read the user_id which is going to be inserted when you press Save button. Means as its not getting populated till one click on save button my lov is not getting refereshed.
Please advice what should i do.
Thanks

Many to many master detail form

Hi All,
APEX 3.1.2 on SuSE 10 Oracle 10.2.0.3 64 bit
I am new to APEX, but used OAS several years ago. Back then I hardcoded all htp.print commands. We are building an intra-team application to track system relationships. For example,
web interface 3 --> application server 2 --> database 6
Our tables are similar to the following
SYSTEMS
system_id (unique sequence)
system_type_id (database, app server, apache, etc.)
SYSTEM_TO_SYSTEM
publishing_system_id - number
consuming_system_id - number
We would like to have a master detail form where we would query database 6 for example, and then see all related systems one level below it (application server 2 in the example above). I have been able to query the related systems and show them in a drop down pick list on the detail form, but I cannot edit them.
The wizard asked for the primary key of the detail table, which in this case is not a sequence generated value, but a pick from a systems table lookup on system_id/system_name.
If the master form would automagically lass the system_id to the publishing_system_id on the detail form, and allow me to update that with a picked system_id tied to consuming_system_id, that would be perfect.
I can write the htp calls I mentioned earlier, but I am sure I am missing something.
Does anyone have any best practices for this?
Thanks!
Steve

Hi Steve,
Here is an example which might help you:
http://apex.oracle.com/pls/otn/f?p=43368:35
Here, I have used two tables e.g. test1 and test2. Test1 has an id column which is just a sequence column and the name column in this table has a unique key.
Table test2 has id column as primary key and name1 column is linked with Test1 table on the Form. Name2 column is not required to be linked with Test1 table.
If this is what you are after, then I can give your more detail for it.
Hope it helps.

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.

Inserting records in master detail form

I am moving an existing Webdb Application to portal. In the application there is a master detail form along the following lines
Dept Id: 10
Dept Name: IMS
Employee ID Employee Name etc
1586 Julie Wilks
Currently users can insert/update/delete detail lines. When inserting, the dept_id foreign key is automatically inserted into the dept_id column in the detail table. My understanding is that for some reason this does not happen in portal. Instead, the user is expected to input any foreign keys manually. As this could lead to all sorts of problems I'd rather not have to do this.
Has anyone found a means to get around this problem?
If solutions have already been posted, please point me in the right direction as a search on the forum hasn't come up with anything.
Many thanks,
Julie Wilks

Hi,
Am I the only one having this problem?
