Update column with parent child relationships

Hi,
i need to update a column with parent child relationship.
Please provide the possible queries..
Gobi..

Hi,
Depending of the objective and the size of the tables, personally, for maintenance purposes, I preferred duplicate the parent with the new column value and duplicate the child records with this same new value. Other alternative is disable the foreign key temporarily.
You can take a look on this link below too:

Material with Parent Child Relationship

Hi,
Need some advise.
We have this scenario, use purchased materials (.e.g Computer bundle with mouse, monitor and keyboard). We need to track these components separetely at different cost and update inventory with serial no.
Upon creating Sales Order for the above materials, how to we ensure that the full set of materials is picked and delivered. As each components has it own material code.
Is there possible to link up these materials with some sort of parent child relationship? And how to handle it in SAP MM and SD moduld.
Thank you.

Peck,
Unless I am missing something, this is not a Materials Management issue, it is a Sales/Distribution issue.
I think the easiest way is to check the 'complete dlv.' (Complete Delivery) checkbox on the Sales order (VA02>Sales Tab).
When this flag is set, none of the items in the sales order can be confirmed unless all of them are confirmed. All confirmations must be for the same day. No delivery can be created unless all items are deliverable.

Baseline project gantt with parent-child relationship

Hallo,
I'm trying to produce a baseline project gantt like the one I found on: http://apex.oracle.com/pls/apex/f?p=36648:85:997721269859901::NO:::
I want to show planned dates and actual dates using this query:
select null link,
NOME task_name,
ID task_id,
ID_P parent_id,
PREV_START actual_start,
PREV_STOP actual_end,
round(perc) progress,
nvl(DATA_START, prev_start) planned_start,
nvl(DATA_STOP, prev_start) planned_end
from GANTT
but since it looks like it's impossible to show null dates in actual_start I exchanged them so that I have planned dates in the blue line and actual dates in the green one.
It works fine If I have simple tasks but If I have a child, Apex does not display the so called planned line (the green one) anymore, I cannot understand why.
Could you please help me?
Could you suggest me any tutorial about Apex Gantt?
Thank you very much,
Valentina

Thank you VC,
I've already read the tutorial and it's useful but it's only about resource gantt in apex while I'm interested in project gantt.
Hope someone has already done something like this.

Insert Record with Parent/Child Tables doesn't work with Oracle - unlike AC

Hi,
I just Migrated a MS Access 2010 Database to an Oracle 11g Backend with the SQL Developer Tool.
The Migration went fine, all the Tables and Views are migrated.
I'm working with MS Access as Frontend.
The application has some Datasheets with Subdatasheets with Parent/Child Relationship. (1-n Relationship)
After changing to Oracle, it's not possible, to Insert a new Record in a Subdatasheet I always get the following Error Message:
"The Microsoft Access database engine cannot find a record in the table 'xxxx' with key matching field(s) 'zzzzz'"
It used to work perfect with the MS Access Backend, do I need a trigger which first adds the child Record ?
Or what should I do?
Thank you

Hi Klaus,
Thanks for your answer. I still haven't solved my problem. The only way would be to use a singel 1:n Relationship, but in fact I need a n:m Relationship.
I tried the same scenario with a new Access Application, same result.
To clearify my problem.
Goal: Parent Form with Parent Records, Linked Child Form with Child Records in a Datasheet View => Insert of a NEW Child Record.
I have 3 Tables (table1 = Parent tabel, table2 = Child Table, table12 = n:m Tabel with PK and two FK)
The Recordsource of the Parent Form is Tabel1
The Recordsource of the Child Form is Table2 joined with Table12.
In my Old Access Project, Access Triggered the Insert and filled Table12 with the NEW PK of Table2.
It seems like Access can't do that anymore....
I'm pretty desperate and I'm sure it is just a litte thing to fix.....

Aviod Update of 2 related fields in Parent Child Relationship

Hi,
I have 2 Entity Beans in Parent Child relationship.
The update on the fields of one Entity Bean is causing an update on the fields(Database Column which is having the same) of the other bean
Is their anyway I can aviod that.

How to model parent child relationship with DPL? @Transient?

Hello All,
I want to model a parent entity object with a collection of child entities:
@Entity
public class Parent{
@PrimaryKey
String uuid;
List<Child> children;
@Entity
public class Child{
@PrimaryKey
String id;
I know that the DPL won't support automatic persistence where it'll recursively go through my parent bean and persist my children with one call. Is there a way of applying the equivalent to JPA's @Transient annotation on "children" so I can persist the children manually and have the engine ignore the collection?
If not and I want to return to the user a Parent with a List named "children," do I have to create a new object which is identical to Parent, but doesn't have the BDB annotations and manually assemble everything? If possible, I'd like to avoid defining redundant objects.
Thanks in advance,

Hi Steven,
The definition of persistence is here:
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/model/Entity.html
And includes this: "All non-transient instance fields of an entity class, as well as its superclasses and subclasses, are persistent. static and transient fields are not persistent."
So you can use the Java transient keyword. If that isn't practical because you're using transient in a different way for Java serialization, see the JE @NotPersistent annotation.
In general a parent-child relationship between entities is implemented almost as you've described, but with a parentId secondary key in the Child to index all children by their parent. This enables a fast lookup of children by their parent ID.
I suggest looking at this javadoc:
http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/persist/SecondaryIndex.html
as it describes all types of entity relationships and the trade-offs involved. The department-employee relationship in these examples is a parent-child relationship.

Master Detail - Detail parent child relationship

Hello All,
I have a setup where I have 3 tables. Call them A, B, and C. Table A is the parent table to the child table B. Also table B is the parent table to the Child table C. Is there a way to represent this in Apex? So far I have created two Master Detail forms: Master Detail form one has the relationship A+B and Master Detail form two has the relationship B+C. Can Apex support a Master Detail Detail form.
Also, is there a way to have my detail page editable without linking to another page to save and update?
Please let me know what everyone thinks.
Thanks
Ryan

Hi,
You can google it - so much information is available online. Any how
Parent Child relationship
PK FKBasic example - Parent and Child in real life -similarly the Table_A is having relation with some other Table_B.
Example
Table_A
columns :-
Student_No, Student Name, Student_address
Now the Table_B store the assignment details
Student_No, Subject_1,subject_2, subject_3
Now relation of join is Table_A.Student_No = Table_B.Student_No
With out the TAble_A details -can be identified the Sudent details etc., No - It's Master data - which is not dependent on any other table and Column Student_No- Acts Primary Key which is Unique -through which we can identify a specific details of particular student. Now comes to Table_B - with out the student_No - we can't say whose details of assignments belongs to whom - now the student_No in Table_B is dependent on some other table - now this table acts a child and Primary Key of Table_A acts Foreign Key - that column helps to identify the record.
Master Detail
Reference tablesconcept of understanding is same when - when comes c,c++, java and c sharp - acts the same but inheritance, interfaces, polymorphisms and overloading code of language differs. If you go further j2ee differs

Help needed in retrieving parent child relationship values

Hi,
I have a requirement to get parent child relationship values as below.
Ex: Address table
cont cont_code state state_code
C1 10 S1 1
C1 10 S2 2
C1 10 S3 3
C2 20 S4 4
C2 20 S5 5
C3 30 S6 6
C3 30 S7 7
C3 30 S8 8
I want a result of country/state and corresponding code like below.
corresponding states should be displayed under each country with some space appended to it.
Geography code
C1 10
S1 1
S2 2
S3 3
C2 20
S4 4
S5 5
C3 30
S6 6
S7 7
S8 8
I am using oracle 10g version.
Thanks in advance.

Hi,
When you post formatted text (like your output) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
I think you're saying that you want this output:GEOGRAPHY CODE
C1 10
S1 1
S2 2
S3 3
C2 20
S4 4
S5 5
C3 30
S6 6
S7 7
S8 8
If so, UNION, as Hoek suggested, is a good way.
GROUP BY ROLLUP is more efficient, but harder to understand:SELECT     CASE
          WHEN GROUPING (state) = 1
          THEN cont
          ELSE ' ' || state
     END          AS geography
,      CASE
          WHEN GROUPING (state) = 1
          THEN MAX (cont_code)
          ELSE MAX (state_code)
     END          AS code
FROM     t
GROUP BY cont
,      ROLLUP (state)
ORDER BY cont
,      state          NULLS FIRST
By the way, this looks like a bad table design.
In a relational database, the fact that the name 'C1' belongs to cont_code 10 should only be stored in one place. You have the same information on 3 separate rows.
Also, if 'C1' and 'S1' are both names, they should probably be in the same column, so that (to give just one example) you can find the information about 'x1' without knowing if it is a cont or a state.
A better design would be.NAME     CODE     PARENT     DSCR
====     ====     ======     ====
C1     10          CONT
S1     1     10     STATE
S2     2     10     STATE
S3     3     10     STATE
C2     20          CONT
S4     4     20     STATE
S5     5     20     STATE
C3     30          CONT
S6     6     30     STATE
S7     7     30     STATE
S8     8     30     STATE
If the data is this simple, then the dscr column isn't needed. Whether parent is NULL or not tells whether the rows represents a cont or a state.
To get the results you want from a table like this, you could use CONNECT BY. Using either UNION or ROLLUP, you have to know, at the time you write the query, how many levels there will be in the parent-child tree, and the length of the code is proportional to that depth, and the table has to be changed if you ever need to add another level. CONNECT BY can handle any number of levels, and the length and complexity of the code is the same whether you have just 2 levels (countries and strates), or 7 levels (continents, regions, countiries, states, districts, cities and neighborhoods) or 72 levels. The table doesn't need any more columns, no matter how deep the tree gets.

Creating View for a table with parent child relation in table

I need help creating a view. It is on a base table which is a metadata table.It is usinf parent child relationship. There are four types of objects, Job, Workflow, Dataflow and ABAP dataflow. Job would be the root parent everytime. I have saved all the jobs
of the project in another table TABLE_JOB with column name JOB_NAME. Query should iteratively start from the job and search all the child nodes and then display all child with the job name. Attached are the images of base table data and expected view data
and also the excel sheet with data.Picture 1 is the sample data in base table. Picture 2 is data in the view.

I think what you need is recursive CTE
Consider your table below
create table basetable
(PARENT_OBJ varchar(10),
PAREBT_OBJ_TYPE varchar(10),
DESCEN_OBJ varchar(10),DESCEN_OBJ_TYPE varchar(10))
INSERT basetable(PARENT_OBJ,PAREBT_OBJ_TYPE,DESCEN_OBJ,DESCEN_OBJ_TYPE)
VALUES('JOB_A','JOB','WF_1','WORKFLOW'),
('JOB_A','JOB','DF_1','DATAFLOW'),
('WF_1','WORKFLOW','DF_2','DATAFLOW'),
('DF_1','DATAFLOW','ADF_1','ADF'),
('JOB_B','JOB','WF_2','WORKFLOW'),
('JOB_B','JOB','WF_3','WORKFLOW'),
('WF_2','WORKFLOW','DF_3','DATAFLOW'),
('WF_3','WORKFLOW','DF_4','DATAFLOW'),
('DF_4','DATAFLOW','ADF_2','ADF')
ie first create a UDF like below to get hierarchy recursively
CREATE FUNCTION GetHierarchy
@Object varchar(10)
RETURNS @RESULTS table
PARENT_OBJ varchar(10),
DESCEN_OBJ varchar(10),
DESCEN_OBJ_TYPE varchar(10)
AS
BEGIN
;With CTE
AS
SELECT PARENT_OBJ,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM basetable
WHERE PARENT_OBJ = @Object
UNION ALL
SELECT b.PARENT_OBJ,b.DESCEN_OBJ,b.DESCEN_OBJ_TYPE
FROM CTE c
JOIN basetable b
ON b.PARENT_OBJ = c.DESCEN_OBJ
INSERT @RESULTS
SELECT @Object,DESCEN_OBJ,DESCEN_OBJ_TYPE
FROM CTE
OPTION (MAXRECURSION 0)
RETURN
END
Then you can invoke it as below
SELECT * FROM dbo.GetHierarchy('JOB_A')
Now you need to use this for every parent obj (start obj) in view
for that create view as below
CREATE VIEW vw_Table
AS
SELECT f.*
FROM (SELECT DISTINCT PARENT_OBJ FROM basetable r
WHERE NOT EXISTS (SELECT 1
FROM basetable WHERE DESCEN_OBJ = r.PARENT_OBJ)
)b
CROSS APPLY dbo.GetHierarchy(b.PARENT_OBJ) f
GO
This will make sure it will give full hieraracy for each start object
Now just call view as below and see the output
SELECT * FROM vw_table
Output
PARENT_OBJ DESCEN_OBJ DESCEN_OBJ_TYPE
JOB_A WF_1 WORKFLOW
JOB_A DF_1 DATAFLOW
JOB_A ADF_1 ADF
JOB_A DF_2 DATAFLOW
JOB_B WF_2 WORKFLOW
JOB_B WF_3 WORKFLOW
JOB_B DF_4 DATAFLOW
JOB_B ADF_2 ADF
JOB_B DF_3 DATAFLOW

Question about File Content Conversion and parent-child relationships...

Hello!
     I have read probably every blog, article and SAP Help document on the topic, but I am stuck on this one. I am trying to convert a General Ledger flat file to an IDoc using the classic file --> IDoc scenario. The setup is done and working, but the IDocs are formatted incorrectly and I believe at least part of the reason is how I am converting the file content.
The root of my problem is that the flat file has a parent-child relationship between the document header and the document item and I want to maintain that since the IDoc type (FIDCCP01) has the same structure in the BKPF and BSEG segments.
Here is the flat (non-XML) file layout that is coming into the file adapter:
FileHeader
DocumentHeader
DocumentItem
DocumentHeader
DocumentItem
and so on (until the number of documents is complete
I would really like the content to be converted so that the line items stay under their parent document headers like this:
<FileHeader></FileHeader>
<DocumentHeader>
   <ItemHeader>
   </ItemHeader>
</DocumentHeader>
<DocumentHeader>
   <ItemHeader>
</ItemHeader>
</DocumentHeader>
But I keep getting this, where it lists the document headers first (one after another), and then all of the line items after the document headers like this:
<FileHeader></FileHeader>
<DocumentHeader></DocumentHeader>
<DocumentHeader></DocumentHeader>
<DocumentHeader></DocumentHeader>
<ItemHeader></ItemHeader>
Is is possible to maintain that parent-child relationship from the flat file and pass it over to the XML?
Thanks,
John

EJB 3, OneToMany that Acts As Tree, or Parent Child relationship support?

(Sorry for the RoR reference)
I first searched the forum and found this post that came close, but not exactly what I'm needing since my table doesn't reference the PK:
http://forum.java.sun.com/thread.jspa?forumID=13&threadID=767913
I have a table called Folder that represents a folder hierarchy. It has a 'Path' field and a 'Parent' field, and of course 'ID'. Each Folder knows its parent by the 'Parent' field, which references 'Path', not* 'ID'. Both are Strings.
To find all the children of a Folder, the sql for a PreparedStatment might look something like this (shared for clarity of the situation):
SELECT * FROM Folder
WHERE Parent = ?Question:
What are the proper annotations in EJB 3 / JPA to allow this kind non-primary key parent/child relationship mapping?
Can I specify a named query that handles the logic and then reference it in the OneToMany annotation? Other cool tricks?
Here is what I am trying (no runtime errors, but no results either). (Example simplified)
@Entity
@Table(name = "Folder")
@NamedQueries(value = {@NamedQuery(.......)})
public class Folder implements Serializable {
    @Id
    @Column(name = "ID", nullable = false, updatable = false)
    private Integer folderID;
    @Column(name = "Path", nullable = false)
    private String path;
    @Column(name = "Parent")
    private String parent;
    // v Here's the kicker v
    @OneToMany(cascade={CascadeType.ALL}, fetch=FetchType.EAGER)
    @JoinTable(name="Folder",
        joinColumns={@JoinColumn(name="Parent")},
        inverseJoinColumns={@JoinColumn(name="Path")})
    private List<Folder> children;
    // getters and setters ....
}Thanks!

It looks like the relationship is bi-directional.
Will this work...
// Parent.java
@Entity
public class Parent implements java.io.Serializable {
@Id
public Long parentId;
@OneToMany(cascade=CascadeType.PERSIST,mappedBy="parent")
public Collection<Child> children;
// Child.java
@Entity
public class Child implements java.io.Serializable {
@Id
public Long childId;
@ManyToOne
public Parent parent; // target of mappedBy
}Then, in your code (a session facade?), you'll create the parent first, create the children, then add the children to the parent. Your code is also responsible for maintaining the reference back to the parent.
Parent p = new Parent();
for(int i=0; i<10; i++) {
Child c = new Child();
p.children.add(c);
c.parent = p;
em.persist(p);

Circular Parent-Child relationship among widgets.

I am trying to draw a Bar Graph on a panel which in turn sits on the main
window. The height policy of the panel widget is set to SP_TO_PARENT so that
when the window is resized the panel is also resized according to the parent
window. I have a situation that every time the panel is resized I need to
scale the Bar Graph in accordance with the new panel size and draw it. But
before drawing the newly scaled Bar Graph I am clearing out all the children
of the panel ( I am doing this just to refresh the panel) and then drawing
the newly scaled Bar Graph. But this does not work!!! I still find some
left over from the previous Bar Graph!!! Any help in this matter is greatly
appreciated.
Also I don't understand this circular parent-child relationship. If I assign
a NIL to Parent attribute of all the children of the panel, what will happen
to the Children attribute of the panel? Won't there be any memory leak by
adopting the above procedure of disconnecting a child from its parent? If
so, how do we take care of it?
Thanks in advance!
Alaiah Chandrashekar
The following is the segment of the code which could be useful for clarity:
// Draws the Bar Graph for the first time.
self.ShowChart(TestData);
self.Open();
event loop
when task.Shutdown do
exit;
// When the window is resized
// I am scaling the Bar Graph for the new
// panel size.
when self.window.AfterReSize do
self.ClearChartPanel();
// self.window.UpdateDisplay();
self.ShowChart(TestData);
end event;
self.Close();
Method ClearChartPanel is as follows:
for child in self.<ChartPanel>.Children do
child.Parent = NIL;
end for;

Hello Evandro,
I am listing the steps to create a relationship manually.
1. Create 2 records in the relationship table in console, one for "Married to" and the other one for "Owner". In order to do that the repository needs to be unloaded.
2. Once you create these 2 records in the table through console, load the repository.
3. Log on to the Data Manager.
4. Now as per your example, there are 3 records in the main table, namely
     JOHN
     MARY
     ACME
5. Select only one record in the record list area e.g. JOHN (where you see the list of records)
6. Then, in the record edit area, double click on the relationship tab,
7. New Window opens up.
8. HERE ALL THE OPTIONS ARE GRAYED OUT. But Select the relationship which you want to create, in our case married to.
9. Now select the record MARY in the record list area. (NOT in the pop window, but main window).
10. Then on the top bar menu, select Relationships --> Adds to Group.
11. Now close the Pop window and observe that the relationship has been created between JOHN and MARY.
Let me know if it worked for you. if not, post some more information about your problem such as where you tried to configure and what options were grayed out.
Please update.
Thanks
Shai
I need to do a relationship among the BP where each record in Main Table correspond a BP (Person or Organization).
The relationship should link the BPs as shown below:
Records
1; John
2; Mary
3; ACME
In record 1, I need to say that John is married with Mary, where Married is a type of the relationship and that Mary is Owner of the ACME, where u201COwneru201D is other relationship type.
I have tried to configure a Relationship (where the parent and child tables were the Main Table) in MDM, but I couldnu2019t to do it because the screen for this feature was locked. I need to be certified that the child link exist in the repository.
Thank you.
Evandro.

Doesn't SAP JPA support recursive parent-child relationship (highlighted by "// Recursion"). The same model works in TopLink perfectly.

Sorry for the delayed update..
I see an issue in the WSNavigator. I have a method in my EJB exposed as a web service. This method has a single argument, which is a serializable class containing a few string variables and the above-mentioned Entity with suitable getters and setters for all the class variables.
When I try to select this operation under the WSDL in the Webservice Navigator, I get a stack overflow error. I think it is because WD4J run-time is not able to build the nested tree. Not sure though...I've attached the stack trace below:
Cannot send an HTTP error response [500 "Application error occurred during the request procession." (details: java.lang.StackOverflowError

Import Manager - Import Parent Child Relationships

I have a parent child relationship set up in console.
Kits / Parts.
Has Required = No
Has Quantity = No
I am trying to import the data for the relationship links using Import Manager.
The source is a Excel file.
Item Number <Kits>       Item Number<Parts>
ACC-123                               ACC-1234
ACC-123                               ACC-555
I mapped the Item Number Kits and Item Number Parts.
When I import, I am getting the following error
<b>Import failed. Failed to find the aggregation record from its field values.
Source record no: 1</b>
I am able to import the same record using Data Manager if the file format is Text.
Any help is appreciated.
Helpful answers will be duly rewarded

The key field that you use to load the relationship must be defined as:
Unique................Yes
Display...............Yes
Multilingual..........No
My problem was that I had defined Model Number as multiligual. When I changed this setting and loaded with Update Indices the load worked.
I have not found anywhere in the literature that talks about this restriction. You can create the relationship in the Console. You can load this type of relationship in Data Manager. You can not however load them in Import Manager.

Does table STPOX contain parent-child relationship between components

Hello
I need to get a list of components of SO BOM.
FM CS_BOM_EXPL_KND_V1 exports an output table STPOX.
Does this table contain parent-child relationship between components? If yes , can somebody tell me which fields contain parent child id.
thanks

Hi,
STPOX is not a table, it is a structure & hence there is no storing of data in a structure. The table which stores this info is STPO.
To get the link you can refer to STPO-STLNR & pass this value to MAST-STLNR, this way you can link the child with its parent.
Regards,
Vivek
