Help!The synchronization of master and detail tables

Is there a simple method to synchronize zhe primary key of detail table with master table?

Needin to modify a primary key column is a sure sign of a data modeling deficiency. Primary keys are generally not modified. If they contain children data, trying to modify them is not allowed by Oracle (I received "ORA-02292: integrity constraint (SCOTT.FK_DEPTNO) violated - child record found" when I tried, in 10.2). Any way to revisit this primary key, to be sure it should really consist of those columns? Otherwise, the only way I see to implement what you want is to have an "after update of ..." trigger.

How to show master and detail tables in different pages?

Hi,
Can somebody expalin me how to include or bind the master and detail tables to different pages which are included at runtime.
thnaks,
Naresh.

Hello!
you have ti create a Master/Detail data structure.
In the first page drag the master table, on the second drag a detail table.
It should work out of the box. Selecting a record on the master table selects
the details on the detail table automatically!

Master and Details Tables

Hello Experts,
While entering any transactional document, like DO or SO system enter the data in a Master Table for example in ODLN and DLN1. that is ok
is there any other table in which system keeps the reference. for a document entered.
Help Required.....

Thanks for reply,
actually I was trying to ask that other than ODLN and DLNx tables is there any other table in which system keeps the track for checking the integrity of data / document i.e. like if we have entered document
number 10036,
will system keep the track of this document in any other table other than ODLN and DLNx tables ....

Master and detail table in same block

Master Table - Group Maintenance
Columns - Group ID, Group Desc
Detail Table - Group Usage
Columns - Group ID(foreign key to Group Maint. table), forecast_date, plan_date, actual_date
I am trying to create a form that will display both tables in one tabular block. I want to be able to insert/update both tables from this form. I can't seem to get it to work right. I have tried adding non table items to the master block and updating manually but changes to only the non table items don't change the record status so the form says 'no changes to save'. Any ideas?

I'm not quite sure what's your requirement. Are some rows belonging to the master-table and some to the detail-table? If not, what happens if you change the master-table-attributs in one row. What then with the master-table-attributs in other records?
About the non-database-items:
There is a property "Lock record" at item-level, if you set that to Yes, the record will be marked as changed also if the item is a non-db-item.
Another possibility would be to create a db-view with your master-detail-columns so that every item is a database-item. To write back data you could use an INSTEAD-OF-trigger on the view.

Master and detail in the same page

db11xe , apex 4.0 , firefox 24 ,
hi all ,
i am trying to insert the master and detail data in one step in the same page :
i have two tables (clients) and (tests_administered)
the client table's region contains theses items
client_id
client_name
the other table's region contains these columns -- the tabular region
row selector
test_admin_id -- pk, hidden
client_id -- hidden , this is the one i should populate with values
and more columns
i've done this :
1- removed the condition of the tabular region .
2- Added the request CREATE to the list in condition of the APPLYMRU process -- or :request like ('CREATE')
3- Added new process with following code : -- with sequence before the applymru process and after process row of clients process
for i in 1..apex_application.g_f02.count
loop
apex_application.g_f02(i) := :p2_client_id ;
end loop ;
but nothing happened . why ? what did i miss ?
thanks

Hi,
Create a Master Detail Form through the APEX Wizard
Make sure you choose the Primary Keys for the Master Detail as one of your Column and not the ROW ID.
Selecting an existing Sequence for the Primary Key is preferred.
Select the option the where your Master and Detail appears in the same page.
Initially when you run the page your master and detail will not appear at the same time in the page when your Master Detail Form is in the entry form mode. For this you have to go to your Tabular Form(Detail Form) region, and below you will have to remove the Condition for the display of your Tabular form and set it to “No Condition”.
Now when you run the page both the Master and Detail form will appear together in the create mode but you will not be able to insert or create both master and detail records at the same time when u click the create button. For this the following needs to be done: You need to create a PL SQL Tabular Form process :
Let's say your master form is based on DEPT and your detail tabular form is based on EMP. Make sure the following things are configured:
The DEPT insert/update DML process runs before the new tabular form PLSQL process. (ie) the new PL SQL Tabular Form Process that you create should be inbetween Automatic Row Processing(DML) and Multi Row Update Process , so create the new Tabular Form Pl SQL process with a sequence number inbetween these two Processes.
Make sure you choose Tabular form while creating this PL SQL process.
The new tabular form PL/SQL process executes the following as the source
:DEPTNO := :P1_DEPTNO;
Where DEPTNO is the Foreign Key column in the Tabular Form that links the Primary Key Item P1_DEPTNO of the Master Form.
Finally this new PL SQL process conditionally runs when DEPTNO is null, so you need to add the following condition to the process:
The final step to accomplish in creating both the Master and Detail records at the same time is to make a change in the condition of the Multi Row Update Process. :request in ('SAVE','CREATE') or :request like 'GET_NEXT%' or :request like 'GET_PREV%'
-We make this change so that records get inserted into the Detail table when we click the ‘’Create” button.
Now you can Run your page and create both the Master and Detail records at the same time.
Thanks and Regards,
Madonna

Master and Detail records in the same table

Hi Steve,
I have master and detail address records in the same table (self-reference). The master addresses are used as templates for detail addresses. Master addresses do not have any masters. Detail addresses have three masters: a master address, a calendar reference and a department. Addresses change from time to time and every department has its own email-account, but they refer to the same master to pre-fill some common values.
Now I need to edit the master and detail address records on the same web page simultaneously.
My question is: Can I implement a Master-View and Detail-View which refer to the same Entity-Object? Or should I implement a second Entity-Object? Or can it be done in a single Master-Detail-View?
Thanks a lot.
Kai.

At a high level, wouldn't this be similar to an Emp entity based on the familiar EMP table that has an association from Emp to itself for the Emp.Mgr attribute?
You can definitely build a view object that references two entity usages of the same entity like this to show, say, an employee's ENAME and at the same time their manager's ENAME.
If there are multiple details for a given master, you can also do that with separate VO's both based on the same entity, sure. Again, just like a VO that shows a manager, and a view-linked VO of all the employees that report to him/her.

Insert Master and Detail in the same transaction

I have 2 view objects : Students and Enrollments.
Connecting those view objects, there is one view link :
Cardinality : 1..* (One student can enroll several courses).
This link is exposed in "Students" view object by the property "getEnrollments" and in "Enrollments" view object, by the property "getStudent".
I am try to insert records first in Student table, and Enrollment table in the same transaction.
The primary key for Student table is generatade by a sequence (database trigger)
My code is :
StudentListImpl studentView = getStudentList();
StudentListRowImpl studentRow = (StudentListRowImpl) studentView.createRow();
studentRow.setFirstname(student.getFirstName());
studentRow.setLastname(student.getLastName());
studentRow.setDatebirth(student.getDateBirth());
studentRow.setStatusid("A");
studentView.insertRow(studentRow);
EnrollmentListRowImpl enrollmentRow = (EnrollmentListRowImpl) studentRow.getEnrollments().createRow();
enrollmentRow.setCourseid("C-100");
studentRow.getEnrollments().insertRow(enrollmentRow);
The generated Student ID is not being retrieved by ADF and set up in Enrollment view object. So, database is firing foreign key violation (in Enrollment table - No student ID provided)
How can achieve this goal? Insert in DETAIL table with the key generated for the PARENT table?

Yes, ID attribute in Student EO is DBSequence.
If I insert only Student it works. But when I try to insert an Enrollment for that just created Student (same transaction), the Student ID is not assigned to Enrollment EO.
The code I use to insert Enrollment is :
EnrollmentListRowImpl enrollmentRow = (EnrollmentListRowImpl) studentRow.getEnrollments().createRow();
enrollmentRow.setCourseid("C-100");
My question is :
Since I am creating a new Enrollment row using view link acessors in Student VO (getEnrollments), will the Student ID (just generated by sequence) be automatically assigned to Enrollment VO?
I am totally lost about this (inserting master and detail in same transaction) and I can't find documentation on this topic.

PRISM Master-Details with navigation between the Master and details view

Hi, I have a Master list with accounts and a Details list containing transactions.
The Master list : has a UserControl (AccountListView) and Viewmodel(AccountListViewModel)
The list is bound to an observable collection of type AccountViewModel and has a SelectedAccount property to get the current selected account. Each AccountViewModel has a collection of type TransactionViewModel.
public AccountListView(IAccountListViewModel viewModel)
//this.DataContext = vm;
InitializeComponent();
ViewModel = viewModel;
public Infrastructure.IViewModel ViewModel
get
return (IAccountListViewModel)DataContext;
set
DataContext = value;
//the viewmodel
public AccountListViewModel(IRegionManager regionManager)
this.regionManager = regionManager;
this.AccountList = GetAccounts(); // gets the list of accounts from another layer
public AccountViewModel SelectedAccount
get { return selectedAccount; }
set
selectedAccount = value;
OnPropertyChanged("SelectedAccount");
And the Details view has a user control(TransactionListView) and a viewmodel(AccountView);
public TransactionListView(IAccountViewModel viewModel)
InitializeComponent();
ViewModel = viewModel;
//this.DataContext = vm.SelectedAccount;
public Infrastructure.IViewModel ViewModel
get
return (IAccountViewModel)DataContext;
set
DataContext = value;
//the viewmodel
public AccountViewModel(Business.Account a)
AccountId = a.AccountId;
accountName = a.AccountName;
I created a hyperlink command so that whenever I click on the name of an account from the master list it will navigate to the detail list and set the as the DataContext the account I clicked on. Before I had both Master and Detail lists displayed at the
same time and set the DataContext of the Detail List as the SelectedAccount property(which is bound to the SelectedItem of the Master List) of the Master List. I am not sure how to pass the SelectedAccount when I navigate to the Detail List and set it as the
DataContext of the Detail List.

>>I'm using the reguestnavigate method, but from what I read you can't pass objects as parameters ?
As I mentioned there is a NavigationParameters class that you can create an instance of and pass as a parameter to the RequestNavigate method in Prism 5:
private void NavigateTransaction(AccountViewModel obj)
var parameters = new NavigationParameters();
parameters.Add("accountViewModel", obj);
regionManager.RequestNavigate(RegionNames.ContentRegion, new Uri(transactionview, UriKind.Relative), parameters);
The TransactionView should then implement the Microsoft.Practices.Prism.Regions.INavigationAware interface and retrieve the parameter in the OnNavigatedTo method:
public partial class TransactionView : UserControl, INavigationAware
public TransactionView()
InitializeComponent();
void INavigationAware.OnNavigatedTo(NavigationContext navigationContext)
AccountViewModel myParameter = navigationContext.Parameters["accountViewModel"] as AccountViewModel;
this.DataContext = myParameter;
public bool IsNavigationTarget(NavigationContext navigationContext)
return true;
public void OnNavigatedFrom(NavigationContext navigationContext)
In Prism 4 there is no NavigationParameters class so you either need to upgrade to Prism 5 if you haven't already done so or you could store the parameters to be passed yourself somewhere else. Please refer to the following links for more information and
examples of how you could do this:

How to set the display ratio of master and detail view

Currently, I use SplitApp that contain the master and detail view. And I would like to show the master view on the left half and detail view on the right half. Is there any proper way to adjust this?
Thank you in advance.

You can set the width ratio by adding css. Check this,

Displaying the master and detail records ....

Hi ,
There is a master - detail form. The end-user make some insertions/updates in the detail block...
How is it possible to display these detail records and its master when the user presses a custom button 'refresh' which just requery the records in both master and detail blocks...?????
When i write "to display these detail records and its master " i mean that the current record (the one which the cursor would be focused in ) would be this master record... however,all other records would be displayed as well....
Many thanks,
Simon

From what I understand you want to re-query and go to the record where you were just before re-querying??
Interesting requirement, why you wanna do this? if for the user to see the changes of the updates, that is the default behavior.
You can do this in two ways.
1- in your "Refresh" button save the :system.trigger_record in a parameter :parameter.record_num, for the Master block and after the query you do a go_record(:parameter.record_num) .
BEGIN
     GO_BLOCK('EMP'); --Master Block
     :PARAMETER.RECORD_NUM := :SYSTEM.TRIGGER_RECORD;
     EXECUTE_QUERY;
     GO_RECORD(:PARAMETER.RECORD_NUM);
END;2 you can loop through the block with next_record built-in and an exit condition of a key value you saved in a parameter.
BEGIN
     GO_BLOCK('EMP'); --Master Block
     :PARAMETER.EMPNO := :EMP.EMPNO;
     EXECUTE_QUERY;
     FIRST_RECORD;
     LOOP
          EXIT WHEN :EMP.EMPNO = :PARAMETER.EMPNO;
          NEXT_RECORD;
     END LOOP;
END;Tony

One Master Many Detail Tables

Does anyone know how I can use XE to create a Master-Detail Form using one master table and multiple detail tables? Currently it seems to only allow one detail table.
Thanks.
Pat.

Hello,
I created the following tables (Location, Dept, Emp ). The master table is Location Table and detail tables are emp and dept.
I created view for emp and dept tables then I created the master detail form which was include the location table as the master and the created view as the detail.
But I need to create 3 blocks like in the oracle developer that helps me to insert the records in 3 tables at the same time.
Best Regards,

Master and Document Tables ...

What relation do Master and Document tables have to parent and child tables?
Should I declare all my created tables master and master details ?
how can I establish my relationships, foreign keys and primary keys with all these fields created by SAP ?

Hi Neftali,
You can create UDOs by using DI API, you have many threads talking about it in this forum.
If you don't want to use UDOs (which are very useful) then you should not use MasterData,... tables because this tables shouldn't be modified by using SQL queries. These kind of tables are designed for use with UDOs to avoid the whole management of the Forms for the Add/Update/Find/Delete,... actions.
Have you had a look to B1DE? You can download it from main B1 page in SDN for free and it generates for you the code of your addon for managing many of the aspects of the B1 SDK. You can maybe give it a try!
You can block users from viewing/using specific menus in B1 by using the UI API.

How to insert new records in Master and detail Forms.

Hi,
I am having trouble inserting values in both master and detail view at the same time. The scenarios is I have a Dept Table (View Object-VO1) and Employee Table(View Object -VO2) both linked with a foreign key, as per Default HR schema in Oracle DB XE.
Now I want to insert new record in both Dept(VO1) and EMP(VO2) table via a New page say ( Page2 ). There is a button on Page1 with button INSERT .I can only drag-drop "CreateInsert" operation on that button for VO1 or VO2. So only text box for Dept records are enable to insert data but not Emp records. Is there a way I can insert data in both the tables at the sametime??
Thanks,
MB

Hi MuradRabbani,
You can programmatically call both createInsert Operations,
Add to your pageDef both CreateInsert Operations.
Create a button tha will call insert method from Master (VO1) and then call insert method for Detail (VO2)
Here is an Example code of calling the operations:
DCBindingContainer dcb = ADFUtils.getDCBindingContainer(); //you need ADFUtils.java and JSFUtils.java classes. You can find them in the sample applications in your JDeveloper.
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO1");
oper.execute();
-----------------NOTE: at this point you should have set values that compine the ViewLink on the master in order the detail will know where to link the new record there are many ways to do it.
As an approach try to overrdi the create Method on the in the ViewRowImpl of your Master vo (VO1)
e.g.
@Override
protected void create(AttributeList attributeList) {
//before
attributeList.setAttribute("NameOfAttribute", valueHere);
super.create(attributeList);
After that you should call the operation for your detail VO2
e.g.
DCBindingContainer dcb = ADFUtils.getDCBindingContainer();
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO2");
oper.execute();
The detail record will now have the values from your master automatically.
Regards,
Dimitris.
