Deleting a child..

In the manual, we can found :
quote:
The removeChild() and removeChildAt() methods do not delete a
display object instance entirely. They simply remove it from the
child list of the container. The instance can still be referenced
by another variable. (Use the delete operator to completely remove
an object.)
But you cannot delete an object (only a dynamic property..).
So how can we do it?

Welcome the the world of garbage collection. You must ensure
that there the child object is not referenced by any other object
and the Garbage collector will delete the object. This can be
tricky in Flex 2.0, but in Flex 3.0 you can use the profiler tools
to track references and ensure that objects are deleted.

Hello javyocks,
Thanks for using Apple Support Communities.
Concerning the issue with multiple Apple ID's, please look at the following:

I have multiple Apple IDs. Is there a way for me to merge them into a single Apple ID?
Apple IDs cannot be merged. You should use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.

You can't delete an iCloud account. You can sign-out, or remove the account from devices, computer or related services.

How to delete parent child relation in Toplink

Hi All,
I have 3 tables A,B,C.
In Table A ,I am saving record.
Table B & C has parent child relation.
B-->Parent
C-->Child
So I want to save records in Table A.
And delete from child(C) 1st then from parent(B).
I m writing my code as,
em.getTransaction().begin();
em.persist(Table A);//save in Table A
em.remove(em.merge(Table B));//Remove from Parent
But how to delete records from child table then from parent table.
Thanks
Sandip

If you have a @OneToOne relationship between two entities, the join column information is used to order the SQL when you remove two entities. For example, if I have:
@Entity
public class Employee implements Serializable {
     @OneToOne
     @JoinColumn(name="ADDR_ID")
     private Address address;
...Then the following code runs regardless of the order of the remove calls.
          em.getTransaction().begin();
          Employee parent = new Employee();
          Address child = new Address();
          parent.setAddress(child);
          em.persist(parent);
          em.persist(child);
          em.getTransaction().commit();
          em.getTransaction().begin();
          parent = em.merge(parent);
          child = em.merge(child);
          // order of next two statements unimportant
          em.remove(parent);
          em.remove(child);
          em.getTransaction().commit();If I don't remove the parent and just the child I get the same error you do because of the FK from Employee to Address.

Deletion of child records linked to parent records to be deleted etc..

'Combined with WHEN OTHERS, SQLCODE provides a way for you to handle different, specific exceptions without having to use EXCEPTION_INIT pragma. In the next example, I trap two parent child exceptions, -2292 and -2291, and, then take an action appropriate to each situation:
PROCEDURE delete_company (company_id_in IN NUMBER)
IS
BEGIN
DELETE FROM company where company_id = company_id_in;
EXCEPTION
WHEN OTHERS THEN
DECLARE
error_code NUMBER := SQLCODE;
error_msg VARCHAR2(512) := SQLERM;
BEGIN
IF error_code = -2292 THEN
/*Child records found. Delete these too */
DELETE FROM employee WHERE company_id = company_id_in;
/* Now delete parent again */
DELETE FROM company WHERE company_id = company_id_in;
ELSIF error_code = -2291 THEN
/* Parent key not found */
DBMS_OUTPUT_PUT_LINE('Invalid company id' || TO_CHAR(company_id_in));
ELSE
/* This is like a WHEN OTHERS inside a WHEN OTHERS */
DBMS_OUTPUT_PUT_LINE('Error deleting company, error: ' || error_msg
END IF;
END;
END delete_company;
Sourced from Oracle PL/SQL Programming (3rd edition) P.143
1. Are error_code and error_msg assigned automatically or do I have to include assignments? If yes, how?
2. Where do I get a list of commonly caught Oracle error codes and similar code snippets used for business logic?
3. How would you deal with the situation where you detect a parent while you are deleting a child record? Just warn the user and log it hoping the DBA will review the logs?
4. I work within a project where I could not query any parent-child relationships, using, amongst other queries the following query, and, this means that the programming team might not be creating these relationships within the database (Oracle 11g).
What are the technical risks?
Could I be omitting something, because it seems quite incredible to me that parent-child relationships are not in place?
SELECT a.table_name,
a.column_name,
a.constraint_name,
c.owner
FROM ALL_CONS_COLUMNS A, ALL_CONSTRAINTS C
where A.CONSTRAINT_NAME = C.CONSTRAINT_NAME
and a.table_name=:TableName
and C.CONSTRAINT_TYPE = 'R'

This is bad code, very very bad code. Throw it away and start with a clear idea of what you want to do.
Why is this code very very bad? Because it uses WHEN OTHERS not followed by a RAISE.
Why is this code bad code? Because it uses one WHEN clause instead of several.
Here is an example for handling multiple exceptions:
http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm#BABFBHGA
If your error code does not have a predefined name, define the name yourself:
http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/errors.htm#BABIIEFC
If you keep the WHEN OTHERS at the end, be sure to add RAISE so the exception still exists. If you don't, Oracle will not do the automatic rollback it should be doing.
To answer your question about parent-child relationships, it is very important to have them. They stop you deleting a parent that has children, but they do not stop you from deleting children.

Why does RoboHelp 8 crash when compiling merged HTML help after deleting a child project in TOC

Why does RoboHelp 8 crash when compiling merged HTML help after deleting a child project in TOC? I would be grateful for any assistance.
Here's the situation:
-- I recently upgraded from RoboHelp X5 to RoboHelp 8. I upgraded my projects to RoboHelp 8 projects.
-- One large help system I manage is built such that there is one master project and about 25 child projects. Each of these is its own item in the master project TOC.
-- In RoboHelp X5 I never had any trouble deleting these.
-- However now in RoboHelp 8, whenever I delete one (by opening TOC pod, right-clicking on item in question, and clicking Delete), and proceed to "Generate Primary Layout" (MS HTML Help), the generation/compilation process proceeds as far as "Generating full-text search data" and then the whole program crashes!
Am I doing something wrong? Is there a bug in the software? I have installed patches 8.0.1 and 8.0.2.
Once again, I thank you in advance for any pointers.

How to delete the child record from the database

how to delete a parent and child record from the database can we do it in the servlet and my database is oracle

I'm not sure I understand the question but you could certainly use the JDBC API from within your servlet to access and modify a DB. You could also use an EJB layer to access your DB and accomplish the same tasks.

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();

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.

How to delete a child row

hi, i want to delete a table (QUESTIONBNKMASTER )
i've used delete QUESTIONBNKMASTER ; query for deleting but i got an exception saying that integrity constraint (VTSQBADMIN.FK_CHM_QNO) violated - child record.
i tried for this command delete VTSQBADMIN.FK_CHM_QNO; but it say's table or view doesn't exits.
what can i do to delete the table.
my oracle username is vtsqbadmin.
please reply soon it's a part of my assignment
thanx in advance
cinux

You can do it many ways
1. Delete all records from Child table then delete from master table.
2. Remove the constraints using
DROP CONSTRAINTS VTSQBADMIN.FK_CHM_QNO;
and then delete records from master table.
3. Disable the constraints. and then delete records from master table.

Re

ADF Tree setting focus back to parent node after deletion of child node

Hi,
Is there a way to get the focus back to the parent node (or rather any particular node) in a tree?
I have a use case where we need to get the focus back to the parent node after a child node is deleted.
Currently the focus is shifted to the next node in the tree, but the need is to get the focus shifted back to the parent node. Also the parent node should be re-invoked to populate to get the latest status after deletion of the child node.
Any help/pointers?
Thanks

Thanks for the reply Frank.
I saw the link http://sreevardhanadf.blogspot.in/2012/07/showing-next-row-as-current-row-after.html
However the issue is since I am using custom created tree using POJO tree item (composite object).
calling myTree.getWrappedData() doesn't gives me a handle to JUCtrlHierBinding and subsequent access to JUCtrlHierNodeBinding.
my program gives me data like -
List<MyTreeItem> treeData = (List<MyTreeItem>)treeModel.getWrappedData();
because my tree model is build using -
treeModel = new ChildPropertyTreeModel(items, "children");
where items is List of <MyTreeItem>
Hence I am unable to get a handle using -
List nodeParentList = nodeParent .getKeyPath();
I am programmatically able to invoke the parent node to get the fresh data, only issue is the focus/selection of that node is not happening
Is there a way around?
Thanks

Help on creating and deleting xml child elements using Toplink please.

Hi there,
I am trying to build a toplink xml demo illustrating toplink acting as the layer between my java code and an xml datasource.
After pulling my custom schema into toplink and following the steps in http://www.oracle.com/technology/products/ias/toplink/preview/10.1.3dp3/howto/jaxb/index.htm related to
Click on Mapping Workbench Project...Click on From XML Schema (JAXB)...
I am able to set up java code which can run get and sets against my xml datasource. However, I want to also be able create and delete elements within the xml data for child elements.
i.e. in a simple scenario I have a xsd for departments which has an unbounded element of type employee. How does toplink allow me to add and or remove employees in a department on the marshalled xml data source? Only gets and sets for the elements seem accessible.
In my experience with database schema based toplink demos I have seen methods such as:
public void setEmployeesCollection(Collection EmployeesCollection) {
     this.employeesCollection = employeesCollection;
Is this functionality available for xml backended toplink projects?
cheers
Nick

Hi Nick,
Below I'll give an example of using the generated JAXB object model to remove and add a new node. The available APIs are defined in the JAXB spec. TopLink also supports mapping your own objects to XML, your own objects could contain more convenient APIs for adding or removing collection members
Example Schema
The following XML Schema will be used to generate a JAXB model.
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
     elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:element name="department">
          <xs:complexType>
               <xs:sequence>
                    <xs:element ref="employee" maxOccurs="unbounded"/>
               </xs:sequence>
          </xs:complexType>
     </xs:element>
     <xs:element name="employee">
          <xs:complexType>
               <xs:sequence>
                    <xs:element name="name" type="xs:string"/>
               </xs:sequence>
          </xs:complexType>
     </xs:element>
</xs:schema>---
Example Input
The following document will be used as input. For the purpose of this example this XML document is saved in a file called "employee-data.xml".
<department>
     <employee>
          <name>Anne</name>
     </employee>
     <employee>
          <name>Bob</name>
     </employee>
</department>---
Example Code
The following code demonstrates how to use the JAXB APIs to remove the object representing the first employee node, and to add a new Employee (with name = "Carol").
JAXBContext jaxbContext = JAXBContext.newInstance("your_context_path");
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
File file = new File("employee-data.xml");
Department department = (Department) unmarshaller.unmarshal(file);
// Remove the first employee in the list
department.getEmployee().remove(0);
// Add a new employee
ObjectFactory objectFactory = new ObjectFactory();
Employee newEmployee = objectFactory.createEmployee();
newEmployee.setName("Carol");
department.getEmployee().add(newEmployee);
Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.marshal(department, System.out);---
Example Output
The following is the result of running the example code.
<department>
     <employee>
          <name>Bob</name>
     </employee>
     <employee>
          <name>Carol</name>
     </employee>
</department>

Hi Gurus
A user id has been deleted in cua child system . Is there any way to trace who deleted the user id ?
Change document shows its deleted by CUA_ADMIN , but we cant trace the original id with which the user has been deleted . Please help!!!!!

You have to check it in the CUA (domain) not in the chid system..... always in the child system is going to appear the RFC user used to distribute the changes from CUA.
