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                         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.

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 :-)

Child Table Cache Problem - Only in Environment

Hi All,
I have master-child tables in a page. Master table is based on a VO and child table is based on pl/sql EO. When user updates any child table row and hits on save, I load the same page again by releasing AM. The problem is when the page loads again after update, two records are being shown in child table. One record with old value and other record with the modified value. But in database only record exists and it is successfully updated. If we again hit "Apply" on the page then only the updated record is shown. I am sure this is due to vo/eo caches. But after insert/update, I am forwarding to same page with retain am set to false. So this should clear-off all associated caches. I had even tried to clear vo caches explicitly before redirection. But even this doesnt help. This issue exists only in the environment but cannot be reproduced locally in JDev. Its working perfectly fine in JDev.
Any pointer on the above issue?
Thanks in advance,
Murari

hmm...caching may be happening at webbean level rather than the VO level. You can confirm this by getting the value of VO.getrowcount in processRequest.
For both Classical table as well as Advanced Table, clearcache() method is available to clear the cache of data object for inner table. Call this in processRequest. You can put in a check to call this only when you self-redirect to this page.

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

Master-Child relations with ODP??

I don't understand why I am having problems trying to build a simple master-child table relation with cascade delete using ODP .NET. With microsoft's providers, in the FILL command, you can specify the relationship in the fill command - Fill(dataset_name,relation_name). But in ODP .NET, it doesn't accept the relation_name as the second parameter, just the datatable. Why is that? are there any good examples out there that show working with Master-Child relations populated with Fill()? Any help would be greatly appreciated.

DBAT Child table Reconciliation issue

I have the following environment
IDM 11gR2 (11.1.2.1) Activedirectory-11.1.1.5.0, Database_App_Tables_9.1.0.5.0. Target Database Oracle 11gR2.
I have created a DBAT connector for the Target Database that is having One Master Table and One Child table.
The issue is that the Target reconciliation doesn’t work.
If I run the reconciliation with a single target table it works fine (setting up a new connector for test) but if I run a reconciliation with a target that is having a child table as well it fails.
Summry:
Reconciliation of a target DB with Master-Child Tables is not working.

Filtering not working for newly added child objects in master-detail table

Hi,
I am using Jdeveloper 11.1.1.4 version.
Problem scenario:
Filtering of records is not working for newly created child objects in a master-detail scenario.
Steps to reproduce this issue using HR Schema (using LOCATIONS and DEPARTMENTS table ) :
1. Create Business components (EO's & VO's ) for LOCATIONS & DEPARTMENTS table)
1. Create a .jspx page and insert a readonly master table of Locations
2. Insert a child table (inline-edit table) of Departments and enable filtering
4. For the child table, drag and drop CreateInsert operation as a toolbar button .
5. Create a new child record using the toolbar button and enter data .
6. Filtering on the newly created child record's attributes does not work.
Please note that the same filter works for existing child records.
Any suggestions for resolving this issue?
Thanks,
Vikas

Found from Fusion Developer's Guide the following snippet about QBE functionality :
"+When you create data controls, all data collections will automatically include a Named Criteria node with an All Queriable Attributes criteria. This is the default view criteria that includes all the searchable attributes or columns of the data collection. You cannot edit or modify this view criteria+. "
So, the question is if the implicit view criteria cannot be edited, how else to set the query execution mode to "Both" ?
Shouldn't ADF BC support this by default? Is this a bug?
Note:- If you create a maste-detail table using POJO datacontrols, filter works correctly for newly created child records also .
This seems to be an issue with ADF-BC datacontrols only.
Thanks,
Vikas

Master table unknown child tables

Hi there!
Suppose there is a master table having unknown child tables
And i simply want to delete all the records of master as well as child's.
Kind Regards!

your lov problem can be because of your form modules database interaction property. i have the same problem.in form module properties "INTERACTION MODE" must be blocking.
Abdullah AKOGLU
Q4) I have installed & configured the 8iAS my System is running Ok.But
my Prob. Is that when I invoke the LOV first time it takes too much time
it is ok however but when I invoke it again it takes too much time again.
Is there any way to improve performance of such database etc. activities.

How to identify all the child tables referencing a master table

Hi,
How to identify all the child tables referencing a master table.
Could you please help me...
Thanks in advance...

Hi!
You may use this query:
SELECT master.table_name, child.table_name
FROM user_constraints master, user_constraints child
WHERE master.table_name IN ('REGIONS')
AND master.constraint_name = child.r_constraint_name

Query --- to find all child tables for a master table

Suppose i have a table master .
I want to know all tables which are child tables for this master table .
In other words i want to know all those table names which have foreign key constraint for the master table .
regards
shubha

You may want to join on the owner in case you have multiple schemas with same table names and same primary key names
SELECT c.table_nameFROM all_constraints c, all_constraints p
WHERE c.constraint_type = 'R'
AND c.r_constraint_name = p.constraint_name
AND p.constraint_type = 'P'
AND c.owner = p.owner
AND p.table_name = '&YOUR_MASTER_TABLE'
