Reg:Master Child Details - AdvancedTable

Team,
I have a below requirement.
1.Dept (Master Table)
2.Emp (Child Table)
I implemented above design in Advanced Table in Master-Child Fashion.
Please suggest me how to implement the below requirement .
1. I should allow the user add rows in Child Table. But For Dept(*IT*), i should render the child table as either read only or disable Add Row Button.
2. Can we implement dependent poplist in Master-Child Table ?
Regards
Sridhar

Sridhar
I know u Discuss about Master Detail page.
When User Select row of Master table a Event is fire we capture that event and find out That Dept name of that perticular row if Dept is IT then we Set SPEL value of Detail Table is true for Read only.
I hope it will Help U

Office 2013 - SharePoint Web App: How can I link a subform on two Master/Child controls?

I have a form in which I have placed a subform in a SharePoint Web App.
I also have 2 controls on the form, from which I'd like to link to two columns on the subform. How can I have two Master/Child linking relationships to a subform.
In Access desktop, it is done in a window "Subform Field Linker", like this:
Master Fields: Child Fields:
<sorry I could not include a link until my account is verified>
Thanks,

Hi Bruce,
>>Are subforms in web apps different in this regard?<<
Yes, there are two kinds of database. In an on-premise environment, Access 2013 apps are hosted by SharePoint 2013 while the data is stored in SQL Server 2012. SharePoint 2013 provides authentication, authorization, and security for Access 2013 apps.
The back-end tables, views, macros, and queries are stored in a SQL Server 2012 database.

Master table, detail table, detail table not getting refreshed selection

i have a page where i am displaying data as master table and detail table. both table VOs are based on SQL queries which use bind variables.
i have a view link between vos of type 1:M
i created master table detail table page by dropping detail iterator from data control panel under master and selecting master table detail table
on my page i see detail table records getting populated only for first record of parent table.
on changing parent record, child table shows same records and does not refresh
i am using partial triggers on both tables to be populated on a button click as i need to pass some bind variables to VOs which are taken as input from users
how can i show corresponding rows in detail table when parent record in table changes
will i have to use table selection listener
is it possible declaratively to have master detail table view when both VOs have bind variables

Instead of doing the master-detail layout by dragging the details over, can you try a new page where you first drag the master VO over and then drag the detail VO over, and then set partialTrigger from the detail to point to the master?

Master-Child-Grand Child problem [Solved]

I've created a form with one master, a detail for this master and a detail for the detail (next generation too is created!). Once i query the master, the detail and the subsequent generations automatically show the required data, but if i click on the child (Generation 1) the data in the child and the subsequent generations is lost. Is this a form bug? Am I not supposed to use multiple generations in a single form - because it is too convenient!

Hi Gerd,
I apologise for the partial information provided. The problem occurs with a mouse-click and not keyboard movement.
Let me explain briefly. I have 3 data blocks A, B and C.
A -> Master block. (No of records displayed 2)
B -> Detail block of A (No of records displayed 5)
C -> Detail block of B (No of records displayed 10)
I query the block A and the blocks B & C get populated with respective values for the first record in A. Now i'd like to view the values in block C corresponding to the 2nd record in B. If i navigate through blocks (from A to B)using keyboard everything is fine. But if I simply click on record #2 of block B, the records in blocks B & C disappear. I have to requery A and then navigate using keyboard only.
I hope i could explain the problem clearly.
Thanks,
Sudhamshu

Maintaining Master-Child relationship during ODI transformation

ODI Gurus
For following requirement, we need the best approach to transform data from Source to Target instance(Both Source and Target instances are running on Oracle Database)
Tables in Source Instance
a) Source_Master
b) Source_Detail (One to many relationship with Source_Master)
Tables in Target Instance
a) Target_Master
b) Target_Detail (One to many relationship with Target_Master)
In ODI need to create interfaces to transform data from
a) SOUCE_MASTER table to TARGET_MASTER table and
b) SOUCE_DETAIL table to TARGET_DETAIL table
NOTE: Value for Primary Key column in Target Instance tables Target_Master and Target_Detail are generated from Database Sequence.
Once the transformation is completed using ODI, the master-child relationship should be maintained in Target Instance between Target_Master and Target_Detail table. How do we achieve this in ODI ?
Thanks
Uma Shankar

For this, create the first interface for MASTER, in the mapping for the primary key you should map the database sequence, something like: MYSCHEMA.MYSEQUENCE_NEXTVAL.
Create the second interface for DETAIL, and on the sources pane of the interface, drag the SOURCE_DETAIL and TARGET_MASTER datastores. Make the joing between the two using the keys from the source. In the Primary key mapping of the DETAIL_TARGET make sure you select the new PRIMARY KEY of the TARGET_MASTER, mapping in staging area. This "lookup" will be done in the target data server.
If you are going to be doing updates and inserts in the target, you should make sure you set the Update Key selected for each of the targets to the same keys as on the source (obviously you won't have the target values!)
If you are not going to do any updates, then use the IKM SQL Control Append rather than the incremental update IKM.
You can optionally set the COMMIT option of the first interface to NO, and only commit on completion on the second interface if you want to ensure the full 'all or nothing' transactionality - but bear in mind, large volumes of uncommitted changes use resources....

Pagination for Master Form, Detail Table

Hi,
I am using JDev11.1.2.1.0
I am creating a page having master detail relationship (master as a form and detail as a table). On click of First, Prev, Next, Last pagination button of master should change the data and refresh child table data.
So created a Master VO & Child VO joined with View Link and dragged into page as Master form, Detail table. But during pagination, NEXT works once, then it seems to stop there. LAST works and FIRST & PREVIOUS seem to both go to the first record.
Can anyone suggest me when I went wrong.

Yes Frank, its st. forward use case. I tired with master table with detail table works fine but master form with details table behaviors differently.
Below snippet of code in JSPX page master form detail table as shown below :

Displaying master child relationship using datatable??

Doubt about Master-Child relationships.

Hello,
I've a doubt about master-child relationships.
Any row in the master table need to has at least one row in the child table. What do I guarantee that?
Please, any ideas.
Thnx.

If im correct you are asking that any row in master table should have a corresponding child record in detail
(transaction) table.
WELL , There is no compulsion that the child table should have a record linking to record in master table.
Master table is not depended on child table. Child table is dependent on data reference on master table.
Pls note that Master table is independent of the child table ( in terms of data reference only) .
This doesnt mean that if you want to delete the master records when child records exists. it gives an error in that case.
check the following example
SQL> create table master(n number primary key);
Table created.
SQL> insert into master values(1);
1 row created.
SQL> create table child(t number references master(n));
Table created.

Get all records in multi selected master child tables

Hi,
I am using JDeveloper 11.1.1.4 version and using ADF-BC in my project.
I have a simple master child[one to many] relationship in my project.
In my view page,I display this master child [Ex: EmpVo1--->DeptVo2] as tables.
I have multi-slection enabled for master table.
My requirement is that,on multi selecting the rows in master tables,I want to get all the child records in my backing bean.
that is if a master row has 3 child records and another master row has 4 child records and on multiple selection of these two records in master table,I should get all the child records in my backing bean.
I need this to implement cascade delete functionality.
Following is sample piece of code
1) called on selecting the rows in master table
public void onRSCGrpSelect(SelectionEvent selectionEvent) {
// Add event code here...
ADFUtil.invokeEL("#{bindings.RscGroupVO1.collectionModel.makeCurrent}",
new Class[] { SelectionEvent.class },
new Object[] { selectionEvent });
RowKeySet rowKeySet = (RowKeySet)tblRSCGrp.getSelectedRowKeys();
CollectionModel cm = (CollectionModel)tblRSCGrp.getValue();
for (Object facesTreeRowKey : rowKeySet) {
cm.setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData =
(JUCtrlHierNodeBinding)cm.getRowData();
Row row = rowData.getRow();
System.out.println("\n" +
row.getAttribute(0) + " :: " + row.getAttribute(1) +
" :: " + row.getAttribute(2));
System.out.println("Displaying Child Records");
displayChildRecords(row.getAttribute(0));
2. private void displayChildRecords(Object rscGrp) {
ViewObject rscMapVo = getRscMapViewObj();
RowSetIterator rsI = rscMapVo.createRowSetIterator(null);
while (rsI.hasNext()) {
Row row = rsI.next();
System.out.println("\n" +
row.getAttribute(0) + " :: " + row.getAttribute(1) +
" :: " + row.getAttribute(2));
rsI.closeRowSetIterator();
But the problem is that ,it is always giving me the last selected rows child record details
Please suggest the error I am doing.
Thanks,
Praveen

Your problem is that you use makecurrent, which should not be used on a multi select table. Next if you have master detail relationship you should have a view link between them. In this case you can expose a method in you master to get the related child row. No need to get the VO itself as you can use the child iterator accessors to get the child record.
public void onRSCGrpSelect(SelectionEvent selectionEvent) {
// Add event code here...
RowKeySet rowKeySet = (RowKeySet)tblRSCGrp.getSelectedRowKeys();
CollectionModel cm = (CollectionModel)tblRSCGrp.getValue();
for (Object facesTreeRowKey : rowKeySet) {
cm.setRowKey(facesTreeRowKey);
JUCtrlHierNodeBinding rowData =
(JUCtrlHierNodeBinding)cm.getRowData();
Row row = rowData.getRow();
//cast to the right row class
EmpEmpVoRow empRow = (EmpEmpVoRow) row;
// now you cann access the child row iterator
RowSetIterator it = empRow.getDepVO();
//now you cna iterate over the child rows
System.out.println("\n" +
row.getAttribute(0) + " :: " + row.getAttribute(1) +
" :: " + row.getAttribute(2));
System.out.println("Displaying Child Records");
//use hte child rows here
}Not sure if the code compiles out of the box (doing this on the train :-)

Not getting the child details

Hi Friends,
Iam implementing a master detail page.
Here I have taken two sequences...one(emp id sequence) for emp custom table and one (dependent id) for family details.
empid is common column for them. Based on this empid I should get child details (family details)
In my search page,create/update page Iam getting the master details , but Iam not able to get child details for the selected employee.
I have created a ASSOCIATION say EmpFamAO between two EO's (emp table    and   family details table)...................Based on empid column
AND
I have created a VIEW LINK between this EO's from master (EmpFamAO) left side and child(EmpFamAO) right side of the view link editor
But the issue is Iam not getting this common column (emp id) in my child table when querying therfore Iam not getting related child details...when Iam clicking on details icon or update icon .
Let me know for any clarifications.
Thank you.
Aravinda.

Hi Aravind just you have to fallow these methods.
public void createEmployee()
        EmpHeadersEOVOImpl hVo = getEmpHeadersEOVO();
        OADBTransaction tr = getOADBTransaction();
        if(!hVo.isPreparedForExecution())
            hVo.executeQuery();
        Row row = hVo.createRow();
        hVo.insertRow(row);
        row.setNewRowState(Row.STATUS_INITIALIZED);
        Number empId= tr.getSequenceValue("KSK_EMP_ID_SEQ");
        hVo.getCurrentRow().setAttribute("EmpId", empId);
    public void createEmpFamily()
        EmpFamilyEOVOImpl sfVo = getEmpFamilyEOVO();
        EmpHeadersEOVOImpl ehVo = get EmpHeadersEOVO();
        OADBTransaction tr = getOADBTransaction();
        sfVo.setMaxFetchSize(0);
        Row row = sTVo.createRow();
        sfVo.first();
        sfVo.insertRow(row);
        row.setNewRowState(Row.STATUS_INITIALIZED);
        Number familyId= tr.getSequenceValue("KSK_FAMILY_ID_SEQ");
        String empId = ehVo.getCurrentRow().getAttribute("StudentId").toString();
        sfVo.getCurrentRow().setAttribute("FamilyId", familyId);
        sfVo.getCurrentRow().setAttribute("EmpId", empId);
now above first method show for master table and
second one show Child Creation methos
so in that method we are inserting empid into Child table and inserting child id also.
So now your requirement will fullfill.
Let me know if required any details.
Thanks
San

        OADBTransaction tr = getOADBTransaction();

Master Child Table

Hi,
I am using JDeveloper 11.1.1.4 version.
In my page I have master child relation to be displayed.
I am displaying this by following the standard adf-bc master child example.
i.e add the id of the master child as partialTrigger to the child table.
But my requirement is that, multiple row selection is enabled for the master table and when multiple rows are selected in master table,
child table should not display any records.
How can I achieve this??
Also,I have a details panel displayed right under master table which displays selected row values in a form.
Here also,when multiple rows are selected,I should not display any values in the details panel.
Please advice on how to achieve this.
Thanks,
Praveen

Hi,
have a selection listener set on tabe to bean method and in bean getAllSelectedRowKeys from table. If you get more than or equal 2 entries hide the detail panel or write code so that u reresh ur detail vo to contain no rows

Master Child tables how to get the latest rows from both

Hi,
Need some help with the sql. I have two tables Master & Child. In my Master table I have multiple rows for the same record and in the child table also multiple rows for the same master row how can I get the latest one's from both.
For example Data in my Master table looks like
CONT_ID                  SEQ_NUM        DESCRIPTION
1                         189             Update 2
1                         188             Update 1
1                         187              NewNow in the child table for the same CONT_ID I may have the following rows
CONT_ID                   UPDATED_DATE                                     STATUS
1                        3/16/2010 2:19:01.552700 PM                          P
1                        3/16/2010 12:29:01.552700 PM                         A
1                        3/16/2010 12:29:01.552700 PM                         P
1                        3/16/2010 12:19:01.552700 PM                         NIn my final query how can I get the row with seq_num 189 as it's the latest in Master table and from child table the row with status of P as it's the latest one based on the time. Here is the query i have but it returns the latest row from the child table only and basically repeats the master table rows as opposed to one row that is latest from both:
Thanks

Hi,
You can use the analytic ROW_NUMKBER function to find the latest row for each cont_id in each table:
WITH     got_m_rnum     AS
     SELECT     cont_id,     seq_num,     description
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         seq_num     DESC
                       ) AS m_rnum
     FROM    master_table
--     WHERE     ...     -- any filtering goes here
,     got_c_rnum     AS
     SELECT     cont_id, updated_date,     status
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         updated_date     DESC
                       ) AS c_rnum
     FROM    child_table
--     WHERE     ...     -- any filtering goes here
SELECT     m.cont_id,     m.seq_num,     m.description
,     c.updated_date,     c.status
FROM     got_m_rnum     m
JOIN     got_c_rnum     c     ON     m.cont_id     = c.cont_id
                    AND     m.m_rnum     = c.c_rnum
                    AND     m.m_rnum     = 1
;If you'd like to post CREATE TABLE and INSERT statements for the sample data, then I could test this.
If there happens to be a tie for the latest row (say, there are only two rows in the child_table with a certain cont_id, and both have exactly the same updated_date), then this query will arbitrarily choose one of them as the latest.
