Displaying master child relationship using datatable??

Hello,
I want to display master child data using a datatable or a datalist or any other component ( if can be used for this purpose )....I mean i have a particular role and the nominees in that particular role to be displayed...how can this be achieved....any suggestions....thanks in advance.
thanks & regards,
Gaurav.

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....

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

How to output the outline parent-child relationship using a report script?

I'd like to extract the outline's dimension members with it's parent-child relationship using a report script. Anybody can provide a sample script? Thanks.
Example:
DimensionX
-----MemberX
----------ChildX
Output:
Dimension X MemberX
MemberX ChildX
Edited by: obelisk on Jan 11, 2010 5:16 PM

Sorry a report script won't do it. You have two options
1. Use at Essbase Outline API to walk the outline and get it for you
2. Use the Outline extractor available from Applied Olap (it is a free download). It can be run interactively of as a bat file.
Frankly, I would rather use 2 since I don't have to code it myself

Implement Parent child Relationship using SSIS

Could you please suggest the best way which should not impact the performance of data loading, to implement parent child relationship using SSIS.
We have a flat file RECON80.dat which need to be loaded into the database into 2 tables.
Parent Table JobMaster and Child Table RECON80 .
In the flat file we have a fields Jobphase which will get inserted in JobMaster table and the remaning details like EIN, DATE etc will get inserted in RECON80 table.
The Parent table JobMaster has JobId as an identity column which is the Pk of the table and it will get inserted into the child table i.e RECON80 JobId as FK of the child tale.
Please suggest the best possible way to achieve it.

Hi SubhadipRoy, I think you might need to create a procedure for this task.
Because in SSIS, we cannot directly get the Identity ID.
As my experience, there were serveral ways to do. But all are workaround.
So, My suggestion is.
In SSIS:
1. Create a DataFlow
2. Drag a flat source and load the data from dat file
3. Create a procedure which receive the parameter from your data of each row.
4. Drag a OLEDBCommand to the Panel and Invoke the Procedure also don't forget to pass all your rows to the Procedure in OLEDBCommand control.
5. In Procedure, after insert 1 row you could get the Identity ID throuth SCOPE_IDENTITY()
That's it, hope it works for you even this may not the efficency way.
Althrough, I expect someone can give the best way if there is.

Master/Details Relationship using View Links is not not population data

I have problem in generating proper data in master/detail relationship using view links passing three parameters between two custom tables can guide me the steps and process how i will able to generate and acheive this requirement.
very urgent
Please suggest me

Without further details, I'd suggest reviewing the following Section of the Fusion Developers Guide:

Forms Builder Master Child relationship --- column datas gets hided.

Hi All,
I have a screen which have 5 columns. Out of which first 3 columns belong to Table A and 4th column belong to say Table B and the 5th column belong to Table C. There is a master Child relationship between Table A and Table B also between Table A and Table C.
The issue is, i enter the data for these columns in row wise. I enter all 5 columns with value and when i switch to next row, the 4th and 5th column's value gets hided.
Please suggest.
Thanks and Regards,
KirthiRavi

You have relation with
Table A with Table B
Table A with Table Cwhen you switch a record to another record at bloc/table A, it's normal forms behavior it's will hide value of block/table B and C. when your click on associate row of block/table A it will show.
It's the form normal behavior for relationship.Hope you understand.

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.
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?

Your forms mode isn't clear. Is it in enter-query mode or insert mode.
what can you do ?
use a timer in post-change or when-validate-item trigger at deptno item at first data block. because go_block isn't supported by p-c or w-v-t trigger.
and at when timer expire, write your code to go second block and insert/query the associate date from emp table.
Hope you understand.

Visualize master-detail relationships using SQL Edge 1.2

SQL Edge 1.2 released by Bay Breeze Software (http://www.baybreezesoft.com) is an Eclipse Rich Client application that allows users to execute SQL queries, browse schema information, and visualize master-detail relationships.
With SQL Edge, users can use only one query to retrieve data in a master table, and then browse data in all related detail tables. Users can also insert, edit, and delete table records in the data grids.
SQL Edge has four perspectives. The Query Perspective allows users run any SQL queries, while the Schema Perspective displays table schema information. There are two relationship perspectives. The Relationship Table View displays data in the master-detail style. The Relationship Tree View displays master table records as top-level tree nodes. The nodes can be expanded to reveal any level of related detail records. In addition, clicking any node will display the corresponding data in a detail grid.
The following summarizes SQL Edge's major features:
(1) Support any JDBC compatible databases.
(2) Allow users to specify JDBC drivers at run-time, and provide wizards to help setup JDBC connections. Easy to install, and easy to setup.
(3) SQL editor with syntax highlighting based on currently connected databases.
(4) SQL edtior allows users to execute SQL queries asynchronously. Users can cancel the execution by click the "Cancel" button or just close the SQL Editor.
(5) Schema perspective displays the table schema information, including column definitions, primary key, indexes, and foreign keys.
(6) Relationship table view displays the related data in master-detail style, with master table data shown in the top grid, and all related detail table data in a list of bottom grids.
(7) Relationship tree view displays the master table records as top-level tree nodes, and the related detail records as child nodes. Click any of these tree nodes will display the corresponding record data in a detail grid.
(8) Allow users to insert, edit, and delete records in the master and detail grids of the relationship table view and relationship tree view.
(9) Allow users to define master-detail relationships even between tables in different databases. This enables the relationship table view and relationship tree view to display data relationships between tables in different databases or without pre-defined foreign keys.

Hi, Martin.
Maybe you don't need a master detail relationship. Do you need to do changes in your detail block, or just queries?
If just queries, you can create your second block based on a From-Clause Query, and change the QueryDataSourceName property with a When-List-Changed trigger in your T-List.
I know this is a little vague but, without knowing what you need to do in the second block, I'm afraid to tell you more.
Feel free to mail me directly, if you need some pointers about Forms.

Help needed: modeling master-detail relationship using Object types

I would like to use object types to model a master-detail relationship. For e.g.
create or replace type detail_t as object
(id number,
name varchar2(20)
create or replace type details_t as
table of detail_t
create or replace type master_t as object
(id number,
name varchar2(20),
details details_t
If I don't use database object-tables, how can I return multiple master rows of the type above from a PL/SQL procedure? Can I return a cursor of some sort?
I'm using Oracle 8.1.7.
Thanks,
Niranja

Niranjan,
After the object types are defined, your data would come from either object tables or object views. In your case, to get multiple master rows, simply query the object view.

Geoff

How to achieve parent-child relationship using self join?

my table structure is as follows
parent child name
-1     1     A1
1     2     A2
1     3     A3
how to achieve the hierarchy model using self join. this can be easily achieved using "connect by prior". but how to achieve the same using self join?

Hi,
Yes, that's definitely possible. If you only need to display two levels from the hierarchy, a self-join is a good option. Make it an outer join if you need to show everyone on one level, regardless of whether they have a match on the other level or not; for example, if you want the output:
child_name     child_id     parent_name     parent_id
A1          1
A2          2          A1          1
A3          3          A1          1It's good that you posted some sample data. Now post the results you want from that data, and your query (what you think is the best attempt you've made so far). If you haven't tried anything so far, then look at some other simple self-join to get ideas.

Fetching parent-child relationship using API or XSD parsing?

Hi,
I would like to fetch all children of a parent object. I did not see any API to provide this information. I tried with GetMapping API, however it does not provide list of all child objects.
E.g. Fetching all child of "Account" object should return all child objects {Activity, Address, Asset, Attachment, Business Plan, Claim, Deal Registration, Financial Account, Financial Account Holder, Financial Plan, Lead, Message Response, Note, Objective, Opportunity, Policy, Policy Holder, Revenue, Service Request, Special Pricing Request}
Is it possible through API? If not, then XSD parsing seems to be the only way to retrieve children. Any guideline or rule on XSD parsing to get list of all children. XSD parsing doesn't look a good solution. Any other way to do so?
This information is crucial for us. Please provide input.
Thanks

RavishHi Ravish,
Any success on this one? We are hurdling the same difficulty as of the moment. We are basically building a plugin that will remotely (and automatically) import a CRMOD object's data model. That goes to say also that we're relying on CRMOD's web services for our solution.
I've read from the Web Services on Demand Guide that GetMapping is suppose to "Return the display names and XML tags of the fields of a record type *or one of its child components*..."+. It seems that this translates to - if you want the list of fields for a child component, you have to run GetMapping on the child component. If this is the case, what other available web services calls can we make to get the relationship hierarchy of a CRMOD object? Any help would be greatly appreciated.:-)
Thank you,
John

Regarding generating levels in the parent-child relationship--- using BODS

Hi Experts,
I got a problem in generating the level for the child attribute at which it stands in the hierarchy. I have 2 columns in my input file one for parent_no and other for child_no. I need to generate the level of the child_no in the total hierarchy structure. I used vertical hierarchical_flattening but it is not generating the requied output, it is generating the tree structure for each and every node in the hierarchy.
What I need is my output file must contain the same number of rows as the input file and it must have an added column to it showing the level the child_no is in the hierarchy.
Kindly, give me some suggessions for aquiring the same.
Thanks in advance.

Create Operation for Master-Detail Relationship Using Composite Association

My requirement is to insert record for both the master and the detail at the same time using a single create insert action.I was successful in doing so using the composite association but when I am trying to commit the new record, I am getting the error that for the primary key Null value cannot be inserted.Then, I made the PK for both the master and detail EO's as DBSequence type which resolved the issue.
My query is , Is there any alternative way to fulfill my requirement by "NOT" using the type for primary key to be DBSequence type?
Thank you for your help.

I also want to insert into master detail table in single form but when I insert in master form and then go to detail form for inserting value the master data automatically loss when I press detail create insert button. I am Using Two create insert button one for master and one for detail.
I have also tried this function for solving my problem in other way but the problem is same
public String cb8_action() {
// Add event code here...
BindingContainer bindings =BindingContext.getCurrent().getCurrentBindingsEntry();
//OperationBinding operationBinding = bindings.getOperationBinding("CreateInsert");
//Object result = operationBinding.execute();
OperationBinding operationBinding1 = bindings.getOperationBinding("CreateInsert1");
Object result1 = operationBinding1.execute();
if (!operationBinding1.getErrors().isEmpty()) {
return null;
return null;
Please Help me.

Issue with Master and child relationship,viewlink

Hi Frnds,
In one of our custom pages we have Master child relationship between Invoice lines and their distributions.
Things work absolutely fine when total no of distributions(say 10) are equal to max no of distributions that can be shown on 1st page(i.e equal to advancetable property value 'Records displayed'..say set as 10)
What happens is when in advance table I click on next button to navigate to next set of records and then edit some field that have any event..ppr or lov my control by default gets transferred to very first set of records.
!!!!!!!!!!!!!! Also this happens only when no of invoice lines are more than 1.
I not sure whether the issue is with VL,VO,AO or the advance table property.
One simple solution that I have tried is...getting back the focus to the row that is updated but it causes some other problem.
Any pointers will be very helpful
Thanks in advance.
