Union on tables with parent-child records and Sorting
Hi,
I have an application that has an existing query which returns org units (parent and child) from organization table with a sort on createddate + org_id combination
WITH Org_TREE AS (
SELECT *, null as 'IS_DELETED', convert (varchar(4000), convert(varchar(30),CREATED_DT,126) + Org_Id) theorderby
FROM Organization WHERE PARENT_Org_ID IS NULL and case_ID='43333'
UNION ALL
SELECT a1.*, null as 'IS_DELETED', convert (varchar(4000), a2.theorderby + convert(varchar(30),a1.CREATED_DT,126) + a1.Org_Id)
FROM Organization a1 INNER JOIN Org_TREE a2 ON a1.PARENT_Org_ID = a2.Org_Id and case_ID='43333'
SELECT * FROM Org_TREE order by theorderby
I have created a new log table for organization 'Organization_Log' with exact columns as Organization table with an additional 'IS_DELETED' bool column.
Questions:
I need to modiy the query,
1. To display the parent and child records both from the organization table and organization_log table.
2. the sort on the result should be based on 'Organization Name' column asc. First with parent org and the child org underneath it. For eg.
aaa
==>fff
==>ggg
bbb
==> aaa
==> hhh
Any help on how the query should be constructed?
Thanks
gkol@Visakh16,
I am getting...
All queries combined using a UNION, INTERSECT or EXCEPT operator must have an equal number of expressions in their target lists.
The problem is that you will have different number of columns in both log and Organization and Organizationlog tables. UNION/UNION ALL expect the same number of columns.
Try the below:
WITH Org_Log_TREE AS (
SELECT Organization_name,Org_id,Parent_Org_id, IS_DELETED, CAST(Organization_Name AS varchar(max)) AS theorderby,1 AS level
FROM Organization_Log WHERE PARENT_Org_ID IS NULL and case_ID='43333'
UNION ALL
SELECT a1.Organization_name,a1.Org_id,a1.Parent_Org_id, a1.IS_DELETED, CAST(a2.theorderby +'/' + CAST(a1.Organization_Name AS varchar(1000)) AS varchar(max)),a2.Level + 1
FROM Organization_Log a1 INNER JOIN Org_Log_TREE a2 ON a1.PARENT_Org_ID = a2.Org_Id and case_ID='43333'
) ,Org_TREE AS (
SELECT Organization_name,Org_id,Parent_Org_id, NULL AS IS_DELETED, CAST(Organization_Name AS varchar(max)) AS theorderby,1 AS level
FROM Organization WHERE PARENT_Org_ID IS NULL and case_ID='43333'
UNION ALL
SELECT a1.Organization_name,a1.Org_id,a1.Parent_Org_id,NULL AS IS_DELETED, CAST(a2.theorderby +'/' + CAST(a1.Organization_Name AS varchar(1000)) AS varchar(max)),a2.Level + 1
FROM Organization a1 INNER JOIN Org_TREE a2 ON a1.PARENT_Org_ID = a2.Org_Id and case_ID='43333'
SELECT * FROM Org_Log_TREE
UNION ALL
SELECT * FROM Org_TREE
ORDER BY LEFT(theorderby,CHARINDEX('/',theorderby + '/')-1),Level -
Need Sorter java file for sorting the records in webdynpro java
Hi Gurus
I had urgent requirement please give your inputs
In my webdynpro java i need to sort entire records in table
I now we need One sorter java class please provide that java file
please suggest the all the steps how to do
Thanks
renu.1. Implement class comparator wich will compare records according your sort preferencies,
like this:
public class record_Comparator implements Comparator{
public int compare(Object emp1, Object emp2){
// here is your code for return -1if 'before' or 0 if equal or 1if 'after'
int stepId_1 = ((record)emp1).get_someValue();
int stepId_2 = ((record)emp2).get_someValue();
if(stepId_1 > stepId_2)
return 1;
else if(stepId_1 < stepId_2)
return -1;
else
return 0;
than call method sort() with your collection of records,
like this:
Collections.sort(record_collection, new record_Comparator()); -
Need PL/SQL Command for to check all rows value for child record and update
Hi All,
i want to update one field following by
one to many relationship for example
in child applet status field is value is "Closed" for all child record then parent value also should update to closed
Note: if one child record field status is "Open" don't do the update operationYou can do it in single UPDATE operation.
Here is sample & Result:
create table PA (id varchar2(3), name varchar2(12), STATUS varchar2(12));
insert into pa values('001','Cary','Open');
insert into pa values('002','TOM','Open');
create table boy (par_id varchar2(3), id varchar2(4), name varchar2(12), status varchar2(12));
insert into boy values('001','ABC1','Cary','Open');
insert into boy values('001','ABC2','Mac','Closed');
insert into boy values('001','ABC3','Ray','Closed');
insert into boy values('001','ABC4','NALLY','Open');
insert into boy values('002','ABC5','ME','Closed');
insert into boy values('002','ABC6','SHE','Closed');
UPDATE PA
SET STATUS='Closed'
WHERE NOT EXISTS
(SELECT 1
FROM BOY
WHERE BOY.PAR_ID=PA.id

Parent/child records from same table
I want to create a query that is a union such that the 2nd resultset is based on the 1st resultset. I have a table that has parent/child records in the same table.
Table: EVENTS
EVENT_ID
PARENT_EVENT_ID
CREATED_DATE
(other columns)
if PARENT_EVENT_ID is null then it is a parent record, else it is a child record. I want to select all parent records then union them with all the associated child records...something like this:
select * from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null -- All parents
union
select * from EVENTS where PARENT_EVENT_ID in (select EVENT_ID from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null) -- include any children of parents selected from above
This works but it's kind of ugly, I want to avoid using the sub-select in the 2nd because it is a repeat of the 1st statement, is there a way to alias the first statement and just refer to it in the 2nd query?Hi,

Thanks, one question...
I did a test and it seems the child rows have to also satisfy the parent row's where clause, take this example:
EVENT_ID|PARENT_EVENT_ID|CREATED_DATE
2438 | (null) | April 9 2013
2439 | 2438 | April 11 2013
2440 | 2438 | April 11 2013
select * from EVENTS where CREATED_DATE < sysdate - 9
start with EVENT_ID = 2438
connect by PARENT_EVENT_ID = prior EVENT_IDSo you've changed the condition about only wanting roots and their children, and now you want descendants at all levels.
This pulls in record #2438 (per the sysdate - 9 condition) but 2439 and 2440 are not connected. Is there a way to supress the where clause evaluation for the child records? I just want to pull ALL child records associated with the parent and only want to do the date check on the parent.Since the roots (the only rows you want to exclude) have LEVEL=1, you can get the results you requested like this:
WHERE created_date < SYSDATE - 9
OR LEVEL > 1However, since you're not ruling out the grandchildren and great-grandchildren any more, why wouldn't you just say:
SELECT *
FROM events
WHERE created_date < SYSDATE - 9
OR parent_event_id IS NOT NULL;?
CONNECT BY is slow. Don't use it if you don't need it.
If you x-reference my original query:
select * from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null -- All parents
union
select * from EVENTS where PARENT_EVENT_ID in (select EVENT_ID from EVENTS where CREATED_DATE < sysdate - 90 and PARENT_EVENT_ID is null) -- include any children of parents selected from above
The 2nd select does not apply the created_date < sysdate - 90 on the children but rather pulls in all related children :)Sorry; my mistake. That's what happens when you don't post sample data, and desired results; people can't test their solutions and find mistakes like that. -
Cdc- deletion of parent- child records
Hi,
I am working with CDC-consistent feature in odi.
Here my scenario is, I have a record say 120 (primary key) in table A(parent source table) and it is used as a foreign key in Table B.
both child and parent are inserted into the concerned tables of target.
Now i want to delete this 120 record from target parent and child tables.
IN the pkg i arranged the pkg scenarios as follows
odiwaitforlogdata----->source model(with extenwindow and lock subscriber option selected)------>parent pkg scenario------>child pkg scenario----->source mode(with unlock subscriber and purge journal options). ------------> This works fine for insert and update.
odiwaitforlogdata----->source model(with extenwindow and lock subscriber option selected)------>child pkg scenario--------->parent pkg scenario----->source mode(with unlock subscriber and purge journal options). ------------> This works fine for delete.
Can't I achieve these two in one pkg
Please Guide.

Facing problem while deleting a child record in hibernate.
I am trying to update a child records i have following scenario
master record (having one to many assciation with child table cascade=all in .hbm.xml configuration file) ===> customerInfo
detail record set (having many to one assciation with master table cascade=all in .hbm.xml configuration file) ===> customerAccountsSet
i do following steps to update a record
1) get the customerInfo objetc from session successfully
2) get the customerAccountsSet = customerInfo.getCustomerAccounts();
3) traying to add a new customerAccount say customerAccount1 to be saved for the first time without primery key in it
4) traying to update a customerAccount say customerAccount2 to be updated with primery key in it
5) traying to add a delete customerAccount say customerAccount3 with primery key in it
only step 5 is not executed properly as i can still see the deleted record in db , although save and update steps have been successfully completed in db.
can anybody tell me whats going wrong here.code for steps 2,3,4,5 is as follows in the same order
2)Set customerAccountSet = (Set) customerInfo.getCustomerAccounts();
3)customerAccountSet.add(customerAccount);
4)customerAccountSet.add(customerAccount);
5)customerAccountSet.remove(customerAccount);Hi Nitesh,
1) Java stack should be up while trying to connect to R/3 backend.
2) You can check the JCOs by doing the following:
Type the following url http://<server name>:<port number>
Click on Webdynpro Console
Enter the user name and password.(You need the system admin right on the EP to do the same)
You can find the JCOs.
3) Better you contact the basis guy who had created the JCOs earlier and get the JCOs tested.
Hope it helps.
Regards.

To find all the child records are processed before parent records
Hi,
When i am trying to process consignment pulls and my client is using third party tool to insert the data into interface tables. My logic is written in such a way that it should pick parent record associated with child but there is some delay in child records and not all the child records are being pulled with parent.
In a brief, i need to write a condition in such a way that my parent cursor should pick all the child records with max(last_updated_date) and then it should be processed.
eg: I have a family and need to catch bus with all my family members. I need to check now for the last family member who get into and should wait for atleast 2mins so as to ensure all my family members are in. I am unable to achieve this with count. Please do revert back soon.
Details are below:
CURSOR c_pull (p_pull_id NUMBER) IS----------------------------------parent cursor
SELECT ecp.ROWID ROW_ID
,ecp.*
FROM consignment_pulls ecp
WHERE ecp.process_flag IN ( 2, 3 )
AND ecp.pull_id > NVL(p_pull_id,0)
ORDER BY ecp.pull_id
FOR UPDATE OF ECP.PROCESS_FLAG NOWAIT;
CURSOR c_line (p_pull_id NUMBER) IS----------------------------------child cursor
SELECT ecpi.ROWID ROW_ID
,ecpi.*
FROM consignment_pull_items ecpi
WHERE ecpi.process_flag IN ( 2, 3 )
AND ecpi.pull_id = p_pull_id
FOR UPDATE OF ecpi.process_flag;

Edited by: jerry on Apr 5, 2012 12:10 AMHi Helios,
Thanks for the info. But its not a concurrent request something like we can filter with start date and completion date. Its all about selection of records from headers and lines table and not able to make those selection of header records with a delay of say some 2minutes until all the child records are inserted.
Thanks,

Finding the complete hierarchy of all child records for a given root
Hi,
We need to find the hierarchy starting from a given root by exploding the hierarchy of each child present in the hierarchy.
Consider a data as given below.
Seq_no denotes a primary key.
Child_id denotes the child node in the hierarchy
Parent_id indicates the immediate parent of the child record
Root_id denotes the starting point of the hierarchy.
Within a given hierarchy the root_id will remain the same and parent_id will keep on changing as required.
Seq_No Child_id Parent_id Root_id
101 1 NULL 1
102 2 1 1
103 3 2 1
104 4 1 1
105 5 3 1
106 4 NULL 4
107 7 4 4
108 8 4 4
109 9 7 4
110 3 NULL 3
111 4 3 3
112 5 3 3
The requirement is to pull the hierarchy starting from a given root traversing down the path by exploding the hierarchy of each and every child present in that hierarchy. It is explained using below example.
For root_id value as 4, the expected o/p is
child_id path
7 /7
9 /7/9
8 /8
For root_id value as 3, the expected o/p is
child_id path
4 /4
7 /4/7 ---> Hierarchy with root_id 4 gets exploded
8 /4/8
9 /4/7/9
5 /5
For root_id value as 1, the expected o/p is
child_id path
2 /2
3 /2/3 ---> Hierarchy with root_id 3 gets exploded
4 /2/3/4 ---> Hierarchy with root_id 4 gets exploded
7 /2/3/4/7
9 /2/3/4/7/9
8 /2/3/4/8
5 /2/3/5
4 /4
7 /4/7
8 /4/8
9 /4/7/9
5 /5
5 /2/3/5
Also, additionally, if there exist any cyclic child records in the hierarchy, the exploding should stop there itself.

Edited by: 952105 on Aug 10, 2012 10:44 AMMy application tracks the product master that stores a product configuration along with its all child/sub-child records. There exists many such configurations for various parts.
There can exist only one configuration for a given product at any point in time. But, at the same time, this product can be a part of other product configurations too (i.e. it can exist as a child in other hierarchies).
Now, the business requirement is to pull the hierachy starting from a given product (as a root). This should also pull the hierarchy of each child/subchild existing under its hieararchy, if there exist a separate configuration for those child/subchild products.

Hierarchy query showing parent and their child records
I'm a newbie on Oracle using Tora,
I'm Trying to run a query that will show me a hierarchical view of parent and child records in a table.
So far I"ve found a query format like this, but its not working
SELECT employee_id, last_name, manager_id
FROM employees
CONNECT BY PRIOR employee_id = manager_id;
but when running it with my tables and columns I get an error message
saying something 'cannont run CONNECT BY in subquery'
Any ideas?Thanks for all the help, I'm getting the error message
'ORA-01473: cannot have subqueries in CONNECT BY clause'
Here's my actual query
select resource_id, lname, org_id
from std_resource
start with resource_id = 413783
connect by prior resource_id = org_id;
I'm trying to display a hierarchical list of user resource_id's, last names, and org_id's from the std_resource table starting withe resource_id 413783 -
Row wise insertion of Master - Child Record
Hi,
Please help me with below scenario:
I have two tables Master - M and child - C
M Contains M1, M2,
C Contains M1 C1, M1 C2, M2 C3
Currently the ODI inserts data of Table M and then it inserts data of C
But I want the data to be inserted in the below given format
1. M1 should be inserted
2. Then C1, C2 to be inserted, if there is any error while inserting C2, ODI should rollback C2, C1 and also M1.
3. Then it should start with next row of the Master table, and if there is no error while inserting the master and child record, then records M2 and C3 should be commited.
Thanks in advance.
VarmaHi Varma,
I also need the steps for the same scenario. Cezar have given me some work arounds, which is working fine(row by row transformation) but we are facing some problem in commit and rollback. The steps are given in the below link.

Cannot sort child rows in multilevel tree table
Hi,
I originally hijacked a two-year-old forum thread that was vaguely similar to my issue, but a kind forum moderator split my post away
(and deleted my other hijack post asking this same question)
so that my inquiry might be viewable on its own.
Hopefully someone can pay attention to my issue instead of getting it confused with those other old forum threads.
So, here we go ...
Is sorting in a treeTable at a particular level possible? Just want to let you I have tried the following approaches to do this. But it dis not work for me.
I have tree table with 2 levels. I am trying to sort the child rows based on its column say "Display Sequence".
User can type in number in this column which contains input text. On value change event of the this field, all the
child rows in the level 2 need to be sorted. This needs to be done without committing the data. On commit it works,
because it sorts based on order by clause. I want the child rows to be sorted on value change event. Following
various approaches I tried.
TreeModel tModel = (TreeModel)treeTable.getValue();
SortCriterion sortCriterion = new SortCriterion("DisplaySequence",true);
List<SortCriterion> sortCriteriaList = new ArrayList<SortCriterion>();
sortCriteriaList.add(sortCriterion);
tModel.setSortCriteria(sortCriteriaList);
The above code does not work, As "DisplaySequence" is not available in the parent view object.
Here is approach no 2
JUCtrlHierBinding treeTableBinding = null;
JUCtrlHierNodeBinding nodeBinding = null;
JUCtrlHierNodeBinding parentNodeBinding = null;
JUCtrlHierTypeBinding nodeHierTypeBinding = null;
Key rowKey;
Object dispSeqObj;
Number displaySequence = null;
Map<Key,Number> keyValueMap = null;
Set<Key> emptyValueKeySet = null;
Map<Key,Number> sortedKeyValueMap = null;
DCIteratorBinding target = null;
Iterator iter = null;
int rowIndex = 1;
RowSetIterator rsi = null;
Row currentRow = null;
Row row = null;
RowKeySet selectedRowKey = lookupTreeTable.getSelectedRowKeys();
Iterator rksIterator = selectedRowKey.iterator();
if (rksIterator.hasNext()) {
List key = (List)rksIterator.next();
System.out.println("key :"+key);
treeTableBinding = (JUCtrlHierBinding) ((CollectionModel)lookupTreeTable.getValue()).getWrappedData();
nodeBinding = treeTableBinding.findNodeByKeyPath(key);
parentNodeBinding = nodeBinding.getParent();
//rsi = nodeBinding.getParentRowSetIterator();
rsi = parentNodeBinding.getChildIteratorBinding().getRowSetIterator();
keyValueMap = new LinkedHashMap<Key,Number>();
emptyValueKeySet = new LinkedHashSet<Key>();
// Gets the DisplaySequence by iterating through the child rows
while(rsi.hasNext()) {
if(rowIndex==1)
row = rsi.first();
else
row = rsi.next();
rowKey = row.getKey();
dispSeqObj = row.getAttribute("DisplaySequence");
if(dispSeqObj!=null && dispSeqObj instanceof Number) {
displaySequence = (Number)dispSeqObj;
keyValueMap.put(rowKey, displaySequence);
}else {
emptyValueKeySet.add(rowKey);
rowIndex++;
rowIndex = 0;
// Sort the numbers using comparator
DisplaySequenceComparator dispSeqComparator = new DisplaySequenceComparator(keyValueMap);
sortedKeyValueMap = new TreeMap<Key,Number>(dispSeqComparator);
sortedKeyValueMap.putAll(keyValueMap);
rsi.reset();
nodeHierTypeBinding = nodeBinding.getHierTypeBinding();
System.out.println("nodeHierTypeBinding :"+nodeHierTypeBinding);
String expr = nodeHierTypeBinding.getTargetIterator();
if (expr != null) {
Object val = nodeBinding.getBindingContainer().evaluateParameter(expr, false);
if (val instanceof DCIteratorBinding) {
target = ((DCIteratorBinding)val);
ViewObject targetVo = target.getViewObject();
System.out.println("targetVo :"+targetVo);
targetVo.setAssociationConsistent(true);
//ri = target.findRowsByKeyValues(new Key[]{rowData.getRowKey()});
rsi = parentNodeBinding.getChildIteratorBinding().getRowSetIterator();
//rsi = nodeBinding.getParentRowSetIterator();
// Rearrange the tree rows by inserting at respective index based on sorting.
ViewObject vo = nodeBinding.getViewObject();
iter = sortedKeyValueMap.keySet().iterator();
while(iter.hasNext()) {
currentRow = rsi.getRow((Key)iter.next());
rsi.setCurrentRow(currentRow);
rsi.setCurrentRowAtRangeIndex(rowIndex);
//rsi.insertRowAtRangeIndex(rowIndex, currentRow);
rowIndex++;
iter = emptyValueKeySet.iterator();
while(iter.hasNext()) {
currentRow = rsi.getRow((Key)iter.next());
rsi.setCurrentRow(currentRow);
rsi.setCurrentRowAtRangeIndex(rowIndex);
//rsi.insertRowAtRangeIndex(rowIndex, currentRow);
rowIndex++;
rsi.closeRowSetIterator();
AdfFacesContext.getCurrentInstance().addPartialTarget(treeTable);
private class DisplaySequenceComparator implements Comparator {
Map<Key,oracle.jbo.domain.Number> dispSeqMap = null;
public DisplaySequenceComparator(Map<Key,oracle.jbo.domain.Number> dispSeqMap) {
this.dispSeqMap = dispSeqMap;
public int compare(Object a, Object b) {
Key key1 = (Key)a;
Key key2 = (Key)b;
oracle.jbo.domain.Number value1 = dispSeqMap.get(key1);
oracle.jbo.domain.Number value2 = dispSeqMap.get(key2);
if(value1.getValue() > value2.getValue()) {
return 1;
} else if(value1.getValue() == value2.getValue()) {
return 0;
} else {
return -1;
In the above code I tried to perform sorting of DisplaySequence values using comparator, then tried to rearrange
nodes or rows based on sort resurts. But rsi.insertRowAtRangeIndex(rowIndex, currentRow) give
DeadViewException...unable to find view reference. While setting current row also does not work.
Approach 3.
DCIteratorBinding iter1 =
bindings.findIteratorBinding("childIterator");
iter1.executeQuery();
SortCriteria sc = new SortCriteriaImpl("DisplaySequence",false);
SortCriteria [] scArray = new SortCriteria[1];
scArray[0] = sc;
iter1.applySortCriteria(scArray);
Any help in Sorting Child nodes ADF treeTable is appreciated. Thanks in Advance.
AbhishekHi Frank,
Thanks for your reply. I have tried similar approach for sorting tree table child rows based on user specified number and it works. But there is a limitation for this. This sorting works only for read only/transient view object. For updatable view object after sorting, data cannot be saved or updated, as it cannot find the rowid. Here is what I tried
In the ParentViewImpl class,
1. overrode the method createViewLinkAccessorRS, so that this method is forcefully executed.
@Override
protected ViewRowSetImpl createViewLinkAccessorRS(AssociationDefImpl associationDefImpl,
oracle.jbo.server.ViewObjectImpl viewObjectImpl,
Row row,
Object[] object) {
ViewRowSetImpl viewRowSetImpl = super.createViewLinkAccessorRS(associationDefImpl, viewObjectImpl, row, object);
return viewRowSetImpl;
2. Added the following method, which will be invoked on valueChange of DisplaySequence in child row. Expose this method through client interface. This method accept a parameter i.e. parent row key of the child row.
public void sortChildRecords(Key parentKey) {
ViewObject viewObject = null;
String type = null;
if(parentKey==null) {
Row [] row = this.findByKey(parentKey, 1);
RowSet rowSet = (RowSet)row[0].getAttribute("ChildVO");
viewObject = rowSet.getViewObject();
viewObject.setSortBy("DisplaySequence asc");
}else {
Row row = getCurrentRow();
RowSet rowSet = (RowSet)row.getAttribute("ChildVO");
viewObject = rowSet.getViewObject();
viewObject.setSortBy("DisplaySequence asc");
this.setQueryMode(ViewObject.QUERY_MODE_SCAN_DATABASE_TABLES |
ViewObject.QUERY_MODE_SCAN_ENTITY_ROWS);
this.executeQuery();
For custom sort, lets say all the numbers should be display first in ascending order, and null or empty values to be display at the end need to override the getRowComparator method in the ChildViewImpl class,
Here is the code for the same
@Override
public Comparator getRowComparator() {
SortCriteria sortCriteria = new SortCriteriaImpl("DisplaySequence",false);
SortCriteria [] sortCriterias = new SortCriteria[1];
sortCriterias[0] = sortCriteria;
return new DisplaySequenceComparator(sortCriterias);
private class DisplaySequenceComparator extends RowComparator {
public DisplaySequenceComparator(SortCriteria [] sortCriterias) {
super(sortCriterias);
public int compareRows(Row row1, Row row2) {
Object dispSeqObj1;
Object dispSeqObj2;
Number dispSeq1 = null;
Number dispSeq2 = null;
boolean compareRow1 = true;
boolean compareRow2 = true;
if(row1!=null) {
dispSeqObj1 = row1.getAttribute("DisplaySequence");
if(dispSeqObj1!=null && dispSeqObj1 instanceof Number) {
dispSeq1 = (Number)dispSeqObj1;
}else {
compareRow1 = false;
if(row2!=null) {
dispSeqObj2 = row2.getAttribute("DisplaySequence");
if(dispSeqObj2!=null && dispSeqObj2 instanceof Number) {
dispSeq2 = (Number)dispSeqObj2;
}else {
compareRow2 = false;
if(compareRow1 && compareRow2) {
if(dispSeq1.getValue() > dispSeq2.getValue()) {
return 1;
} else if(dispSeq1.getValue() == dispSeq2.getValue()) {
return 0;
} else {
return -1;
if(!compareRow1 && compareRow2)
return 1;
if(compareRow1 && !compareRow2)
return -1;
return 0;
The above solution works properly, and sorts the child tree rows. But while saving the changes, update fails. I also came to know that in-memory sorting is applicable to read-only/transient view objects from some blogs and also mentiond in this link http://docs.oracle.com/cd/E24382_01/web.1112/e16182/bcadvvo.htm
Is there any way that updatable view objects can be sorted and saved as well?
Thanks,
Abhishek

Open dialog box window with checkboxes for each child record - Please Help
Hello Everybody
I have a 10g form with master record and 20 child records. In the child record form, currently there is a “Notes” Editor, which pops up when user click the “Edit” button. In the “Notes” editor, user enters remarks if anything is missing. For example, typical remarks will be: Statement is missing, LOC paper is missing etc.
Now, I would like to replace “Notes” editor with a dialog box. In the dialog box , I would like to add checkboxes with values “Statement is missing” and “LOC paper is missing” etc. along with “Notes” field. The user can select checkboxes. The value of the checkboxes should go in the “Notes” field with the ability to edit it. This way, user doesn’t need to type the most common notes every time.
I have created a “NewNotes” dialog box with checkboxes and multiline text Item. It is pops up when I click on the button. I have also created to WHEN_CHECKBOC_CHANGED trigger for each checkboxes so that the its value will go in a multiline text item.
But, I am not sure how I can link “NewNotes” dialog box to the each record in child record block. I would really appreciate it if anybody could give me some idea.
Thanks,if i understand correctly you have a note item (based on table) on every child record? when you open the dialog box: how do you put data from notes to dialog box? in the same way as you can write it back ...

How to create Child record at the time of master record creation.
Hi,
I have MasterVO and ChildVO. And association between both are 1 to *. I have a requirement like, I need to create row in ChildVO at the time of MasterVO row creation.
I have used entity based association to create view link. This view link created ChildVO accessor in MasterRowImpl as type RowIterator.
Actually my idea is to override create method in MasterVORowImpl and call ChildVO ViewObject and call .createRow() method on it. But I don't have access to ViewObject, instead it gave access to RowIterator.
Could you please provide any pointer to achieve above functionality?
Many thanks in advance.
Jdev version - 11.1.1.7.0
Regards,
Dileep.Hi Tim,
Now it is creating child record at the time of master row creation. But it is working only through BC tester. But when I drag the child VO instance in the jsff page, only master is get created as editable only, child is displayed as read only without populating any default values like child VO surrogate key and other default attributes. But through BC tester it is working fine.
Am I missing anything here while implementing in UI?
Thanks,
Dileep.
