Auto Query in Master Detail Form using dynamic page doesn't work

I created a Master-Detail form, and implement AutoQuery using a dynamic page
with the following code :
<HTML>
<BODY>
<ORACLE>DECLARE
nre_ VARCHAR2(100);
BEGIN
nre_ := emp_nre;
if nre_ is not null then
net_portal.Popula_Agregados(nre_);
net_portal.Popula_Docs_Agregados (nre_);
htp.p('<iframe id=myFrame name="myFrame" frameborder=0 width="250%"
height="300"
src="/pls/portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=
3
388118140&p_arg_names=_show_header&p_arg_values=NO&p_arg_names=_cad_nre_cond&p_a
rg_values=%3D&p_arg_names=cad_nre&p_arg_values='||nre_||'">
</iframe>');
end if;
EXCEPTION
WHEN OTHERS THEN
htp.p(SQLERRM);
END;
</ORACLE>
</BODY>
</HTML>
It works fine when we access the first time to the page, but if i press the
save button after inserting or updating a detail record, the header record is
lost. How can i avoid this situation ?

I changed query:
select
Replace(
'<img src="#IMAGE_PREFIX#ed-item.gif" border="0" alt="EditMap" usemap="#editmap***id***"></img>
<map name="editmap***id***">
<area shape="rect" coords="0,0,16,16" href="http://apex.oracle.com/pls/otn/f?p=&APP_ID.:'
|| decode ( type, 'FOLDER', '33', '22' )
|| ':&APP_SESSION.::&DEBUG.::P'
|| decode ( type, 'FOLDER', '33', '22' )
|| '_ID,P'
|| decode ( type, 'FOLDER', '33', '22' )
|| '_CALLING_PAGE:' || id || ',&APP_PAGE_ID." ></area></map>' ,
'***id***', id
) Edit,
id,
type,
name,
decode ( type, 'FOLDER', 33, 22 ) target
from tThe idea is - each img uses its own map.
It works now.

How to create a master detail form on same page in apex 4.2.1

Hi All,
i need to design a master detail form on same page i am not finding an option in wizard from where i can do that.
will appreciate your suggestions.
Thanks

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 create a MD form using dynamic page ?

Rahul and Sharmila,
You have answered several of my queries earlier and I am thankful for them.
I have been trying to creating a MD form using dynamic page and I haven't fiqured it out. I need help. You both advised me on creating a simple form using dynamic page. The complexity changes drastically when I have to create a MD form. Has no body ever tried to create a MD form with dynamic page?
I haven't heard from you anything either. I am stuck with this and I need help urgently. Would you kindly tell me if this is possible and how ? Otherwise, I will stop crying for help on this.
Thanks for your kind attention.

Master-Detail Form using Oracle XE...

Hi ,
Which type of page (blank , form , ....) should i select in order to create a master - detail form (dept - emp tables on SCOTT schema) in one and just one page (no tabs)...????
And also . . . is it possible the above form to be used for both inserts , updates and deletes...????
Many thanks ,
Simon

Hi Simon,
Use form then Master Detail Form.
You can insert, delete, and update rows.

Hello,
The base idea here is if the record is added successfully you would then get the new primary key then manually add the record to the underlying data source. Does not matter if we are talking a single table or a master-detail setup.
The following shows the basics
https://code.msdn.microsoft.com/Adding-new-records-into-bff5eaaf
All of the above is done without using a DataSet yet the same thing needs to happen with a DataSet, simply focus on the one table.

Problem with Master -Details forms in seperate pages

Hi ,
Below is the scenario:
I have Institution and a department tables where there is a foreign key relation between the tables. So now i have two entity objects for the 2 tables and 2 view objects(DepartmentView,InstitutionView) from the entity objects.
I also have a view link between them.I made a master-detail relation between them in the datamodel using the view link.So my appmodule now has getters for the department view,institution view and viewlink.
I now have a jsp page "createInstitution.jsp" which contains a form for the institution , i have a "next" button on the same jsp which calls a method in my appmodule class .This methods just inserts the record into the Institution view. In this method i am able to see what the user entered in the form by getting the viewrow record like the below code :
InstitutionViewRowImpl newInstitutionRow=(InstitutionViewRowImpl) getInstitutionView().first();
The next button navigates to the next page "listDepartments.jsp" which contains the list of departments that are added. This page has a button "Add Department" which takes to to the "addDepartment.jsp" page which shows a form for adding a department. This page also has a button which calls a method in app module class. The method just inserts the record into the view(DepartmentView)
Here when i say
DepartmentViewRowImpl newDepartmentRow=(DepartmentViewRowImpl ) getDepartmentView().first();
the newDepartmentRow is null.
Also on the addDepartment.jsp form , i had used a output field to see what the parent id was and interestingly the parent id is 75 which is first institution in the database. It should have been "-10" , a temporary id assigned.
Can someone please tell me what is the problem with my approach?

I don't understand why you are using a method on your button to insert the record into the table - An Oracle ADF Form will do the insert for you by default without any coding.
See the create pages in these tutorials:
http://www.oracle.com/technology/products/jdev/11/cuecards/adf_set_21/ccset21_ALL.html
http://www.oracle.com/technology/obe/obe11jdev/11/dev_ui/developuserinterface.html#t2s5
The method that you are calling just returns the first record in the rowset - I don't see how it has anything to do with actually inserting the data into the table.

Master Detail Form - Problem using built in wizard

Hi There
We are working on Application express 2.2.
We are facing problems for a master detail form using Wizard. The
details are as follows : >>
1) Master table : TS_ENTRY_TXN
trans_id P.K.
2) Detail table : TS_ENTRY_TXN_DETAIL
a)trans_id
b)sub_trans_id Composite P.K.(trans_id,sub_trans_id) & these are
based on sequences.
If i try to build a master detail form using the Wizard, the options
for providing P.K. for master & detail are listed which we used.
As it is a master detail form, we want to carry trans_id to the detail
for updations/insertions which doesn't happen.
The MRU fails with oracle error :
Error in mru internal routine: ORA-20001: Error in MRU: row= 1,
ORA-01400: cannot insert NULL into
("TS_APEX"."TS_ENTRY_TXN_DETAIL"."ENTRY_ID"), insert into
"TS_APEX"."TS_ENTRY_TXN_DETAIL" ( "ENTRY_ID", "SUB_ENTRY_ID",
"SMR_ID", "TASK_ID", "SUB_TASK_ID", "TIME_SPENT", "REMARKS") values (
:b1, :b2, :b3, :b4, :b5, :b6, :b7)
Is there any other way to build master detail wihout wizard.
Could you please suggest us better way to complete this task.

If I'm reading this correctly, then one of the columns in your detail tables' primary key is also the foreign key pointing to your master table? If that's the case, then that's not supported by the wizard. For the wizard generated master-detail form to work properly, you'll have to have a foreign key column in your detail table which is not part of your detail table's primary key.
Hope this helps,
Marc

Problem in Master Detail form when using ADF table for Detail

hi,
jdev version-11.1.2.1.0
i have create Master detail form using datacontrol drag as ADF Master Form Detail Table.
Now when i create a new row in Detail table using CreateInsert button a blank new row created on the top of detail table.
and other row show that data of previous record based on master.
problem is that i want when i click on createInsert button all row of detail table should be blank and when user fill two or three row then commit.
Thanks in Advance

Hi,
if a detail table has data, then createInsert adds to these. If you want to hide existing rows, create a new View Object instance and set its "Retrieve from the Database" option to "No Rows". The use an af:switcher to change the table shown when the user clicks the createInsert button. There is a bit of coding required to have this use case in ADF, but its mostly declarative. Bottom line is that there is no automated option other than creating new rows in a separate page or dialog if you are bothered by existing rows

Validating WEBDB2.2 Master-Detail form

I would like to validate a Master-Detail form using Javascript in WEBDB 2.2. There is the option to validate field/forms in other types of Forms (based on Table/View, based on Query, etc...) but I do not see that option in a Master-Detail Form. Any help would be appreciated.
Thanks

Field values erases when Add Row button is pressed in Master Detail Form

Hi,
I am using APEX 4.0. There is a master-detail form in a page, this has 5 rows in it by default, has a Add row and a Delete button. I face two problems now:
1. When the values are entered in all the 5 rows, that are in default, and Add Row button is clicked, these values are entered in the DB, but they are erased from the interface. Means when user clicks Add row he don't see the old values he has entered. All new empty rows are only seen. This might confuse the user. How can I resolve this.
2. The values are saved to the DB only when the Add row button is clicked, so suppose if the user enters some wrong values in the default rows and after he clicks Delete button, all the field values are erased. Is there a way to delete only that particular row? (Please note: the values are not saved to the DB, unless the Add Row button is clicked)
Please let me know how to resolve these 2 issues.
Thanks.

So let me get this straight:
You enter information into a tabular form and then click the add row and the data is being duplicated from the prior row or being inserted into the table ?
Thank you,

Bind variable in Master Detail form

Is there any way to go to a specific master record (bind variable) and it's associated detail information in a master detail form using a link from another report?
Louis

I suspect that he may have the same question I do. Namely, if I have four tables (employees, projects, tasks, and project_assignments) how do I create a master detail form where I can specify the project and the employee via LOVs? The project_assignments table contains foreign keys for employee, project, and task, as well as additional fields relating to the task status.
Currently, I have it set up so that the employee name can be selected and the project is hard coded to the current project.
Is there an easy way to populate the detail records based on two LOVs in the master form?
Thanks in advance,
Fritz

Master Detail Forms

Can somebody please explain to me how to set up a Master Detail form using Apex 3.1.0?
The help system is not very helpful.
I have a Master table whose PK is based on a sequence.
I have a Detail table whose PK is the concatenation of the Master table's PK with a VARCHAR2.
Here is how the form is supposed to work: I enter data on the master and detail sections, click an Insert button and 1 record should go into the master and 1 or 2 records into the detail.
But now I am on the pages that ask me to choose the source for the PK's.
The source for the master is easy -- it's the sequence.
But how do I enter the source for the detail table primary key columns?
The first part of the PK comes from the same sequence number that the master table is based on, so I do not want the sequence to increment once to populate the master table and again to populate the detail table.
The second part of the PK comes from a value that was entered on the form.
So how do I accomplish this?
Do I choose "Existing sequence" for the first PK source and "Custom function" for the 2nd?
Or what?
Thanks for your help. Please be as specific as possible in your answer.

I tried creating a master detail form using a view of the current date's attendance(from the MASTER table) as the detail table AND and the table of all date's attendance as the MASTER table. If I want just the current date's attendance from the MASTER table..how do I get those records the show in the detail of the form?

am desperate & need help urgently for this ASAP.

hello
here is the solution,i hope this might help u.
go to the code of your button and change write the following
go_block('name of your master block');
execute_query(no_validate);
and in the object navigator make the first item in the master
block that it should be displayed in the canvas and it must be a
navigable item too.not a display item.
thank you

Master Detail form - Problems

We are facing problems for a master detail form using Wizard. The details are as follows : >>

trans_id P.K.
2) Detail table : TS_ENTRY_TXN_DETAIL
a)trans_id

If i try to build a master detail form using the Wizard, the options for providing P.K. for master & detail are listed which we used.
As it is a master detail form, we want to carry trans_id to the detail for updations/insertions which doesn't happen.

Is there any other way to build master detail wihout wizard.
Could you please suggest us better way to complete this task.

Hi San Mat,
I would never recommend having a composite PK on any table. Use the sub_trans_id as the PK in its own right and have trans_id as a Foreign Key pointing to the master table.
However, given your existing table structure, what you need to do is add a Default value for the ENTRY_ID field on the child table that points to the Page Item used for the PK field on the master table (you've said trans_id but do you mean ENTRY_ID??). On the column's Column Attributes page, set Default Type to Item (Application or page item name) and the Default to P1_ENTRY_ID (or whatever the name is of field is on the master table's form that holds the PK)
When a new row is added to the child table, the ENTRY_ID from the master table is inserted automatically.
Regards
Andy
