How to inherit attribute values in object tables?

I am trying to implement object inheritance with oracle 10g express. What i have done so far is created some types and subtypes. And some tables based on those types and sub types. So far i have understood that the subtypes inherit the attributes and methods from its super types.
But is there a way to inherit the attribute values from the object table of the super type to the object table of the sub type?
For example: The object O1 , explicitly labeled with (sIPO1 , wIPO1) , also inherits the intended purpose (sIPT 1 wIPT 1) from T1 . Similarly, the object O3 inherits the intended purposes from T3 , O1 and T1 . Note, however, that O2 , which is not labeled, inherits the intended purpose from T2 , but not from O1 nor T1 , as the intended purposes are not inherited through the reference-of relation.
_a visual of the above description [http://picasaweb.google.com/lh/photo/1YBAQbCMQMBmd8oyw9SyNw?feat=directlink]_
How can the types and objects be labeled as mentioned above? And how can these labels be made inheritable by the subtypes and objects based on those subtypes?
Possible Solution*
Only way which i could think of is using relational tables, like this: type_label(type_name, label1, label2) and a similar table table_label(table_name, label1, label2) for labeling the object tables. Then refer to these labels through some java programming. Will this be a right approach. I doubt that this will defeat the very intentions of the object database. And i hope there is a straight solution in Object Relational methods instead of java programming.
nested tables and vararrays... will using them help solving the above problem some how?

From those examples i can see that although the nested tables will have the super type attributes and values with them, if i have to change those attribute values the values in the whole table gets changed.
is it possible to change the super type attribute values which is corresponding to the nested table values alone and not disturb the over all table?

How to display(binding) values in the table from more than one node?

Hi,
I have two nodes (TRIPS & AMOUNTS)in the context. How to bind these values into the table control?
When i bind second one, first one is getting replaced.

Hi Mog,
Of course it is possible to create a table from attributes of more than one node, and in some cases this is still necessary, but you have to do this the hard (manual) way.
If you have a table control, have a look at the properties and the elements belonging to it.
First of all, there is the property "dataSource", which binds to a multiple node (let's name it TableRootNode). This means that for each element of THIS node, one row is created. In each row the data of exactly one element of this TableRootNode is displayed.
Then you have columns in this table. Inside of the columns there is a header and an editor. The editor is the interesting part.
Normally the primary property of this editor is bound to an attribute of the TableRootNode. Then everything works as expected. If it binds to an attribute of a subnode (SUB) of TableRootNode, then in row i the data of the subnode of the i-th element of TableRootNode is displayed. There is no need for SUB to be a multiple node, but it must not be a singleton.
If you bind a property of the editor to an attribute, which does not lie in the subtree of TableRootNode, then you will see the same value in each row.
Now it depends on the structure of your context. Take the node, which is relevant for the change in each row (I assume it is TRIPS) and bind the table to the node as you are used to. Then for each additional column, you have to create a new column in the tree, create a new header element with a title and a new editor (e.g. textview or inputfield) and then bind the right property of the editor to the corresponding attribute in node AMOUNTS).
If these 2 nodes do not have parent-child-relationship, the tip to create a new node, which consists of the attributes of both nodes is the only solution.

Getting the attribute value from a table from page def using el expression.

Hi,
Am using Jdeveloper 11.1.2.0.0 and have a requirement as follows for which a sample is been created. Requirement is as follows..
1. Have a Taskflow that has a readonly table Employee.
2. On clicking of a button called "route" checks if the selected row , Manager id attribute value = 200 then navigate to first page else if manager id attribute value is 200 then navigate to second page.
Through the page def , if it has form , then we can access the attributes like #{data.view_FirstPageDef.ManagerId} . In case of acquiring the same attribute value from table using page def ? is what am unable to get..
Have achieved the routing concept using the Router activity on Taskflow. But am unable to get the selected row attribute value of a table from the employee page def.. Can someone suggest on the same...
Thanks and Regards,
Vinitha G

On the router, right click its icon in the task flow and create a page definition. Then in the page def file, add an iterator based on the same View Object from the table in the first page, then add a value attribute mapped to managerId in the View Object iterator. Finally in the router you can write EL expressions along the lines of #{bindings.ManagerId.inputValue = 200} or #{bindings.ManagerId.inputValue != 200}.

How to get attribute value from standard page ?

Hi,
How to get attribute value from standard page ?
String str = (String)vo.getCurrentRow().getAttrbute("RunId");
But this value is returning a null value ....
Can anyone help me to get this attribute value which is actually having a actual value .

getCurrentRow() would always return null if no setCurrentRow() is used.
Please check the page design and understand how many rows of VO are there. You can also use the following to get the row:
vo.reset();
vo.next();

How to retrieve the values from a table if they differ in Unit of Measure

How to retrieve the values from a table if they differ in Unit of Measure?

If no data is read
- Insure that you use internal code in SELECT statement, check via SE16 desactivating conversion exit on table T006A. ([ref|http://help.sap.com/saphelp_nw70/helpdata/en/2a/fa0122493111d182b70000e829fbfe/frameset.htm])
If no quanity in result internal table
- There is no adqntp field in the internal table, so no quantity is copied in itab ([ref|http://help.sap.com /abapdocu_70/en/ABAPINTO_CLAUSE.htm#&ABAP_ALTERNATIVE_1@1@]).
- - Remove the CORRESPONDING, so quantity will fill the first field adqntp1. ([ref|http://help.sap.com/abapdocu_70/en/ABENOPEN_SQL_WA.htm])
- - Then loop at the internal table and move the quantity when necessary to the 2 other fields.
* Fill the internal table
SELECT msehi adqntp
INTO TABLE internal table
FROM lipso2
WHERE vbeln = wrk_doc1
 AND msehi IN ('KL','K15','MT').
* If required move the read quantity in the appropriate column.
LOOP AT internal_table ASSIGNING <fs>.
CASE <fs>-msehi.
 WHEN 'K15'.
 <fs>-adqnt2 = <fs>-adqnt1.
 CLEAR <fs>-adqnt1.
 WHEN 'MT'.
 <fs>-adqnt3 = <fs>-adqnt1.
 CLEAR <fs>-adqnt1.
ENDCASE.
ENDLOOP.
- You could also create another table with only fields msehi and adqntp and then collect ([ref|http://help.sap.com/abapdocu_70/en/ABAPCOLLECT.htm]) the data to another table.

not too sure what you mean, perhaps you could supply a table description and some sample data
but, consider
delete from table_1 where column_1 is null

ALTER TABLE test
MODIFY (indicator DEFAULT 'I');
Incidentally, INDICATOR is a keyword in Oracle, so you may have problems using it as a column name. If so, you'll have to enclose the column name in double-quotes, and be careful to use capital letters inside the quotes.

How to set default value of a table using sequence number

Dear all,
Does any body know that how to set default value of a table
using sequence number.
But I don't want to use trigger to do that.
Please help!!!!
Eldon

Andrew is essentially correct. You can get around the trigger,
but not the sequence, if (and this may be a very big if) you can
guarantee that every time an insert is done into the table, from
whatever source, the statement looks something like
INSERT INTO tbl VALUES (sequence.nextval,other_columns_values)

How to get attribute value from an object inside an object in Xpress

Does anyone know how to get an attribute value from an object in Xpress in a workflow? I have an object structured as follows:
<ResourceInfo accountId='mj628' tempId='3483372b787ce7dd:-5d99a0c5:130cb238483:-3600'>
<ObjectRef type='Resource' name='Google Apps'/>
</ResourceInfo>
I need if possible to get the name='Google Apps', which is inside the ObjectRef, so I guess its an attribute value of an object inside an object.

If the ResourceInfo object is accessible in a variable, i.e. named "myResInfo", you just have to check the Java API and call the relevant method:
<invoke name='getResourceName'>
<ref>myResInfo</ref>
</invoke>

How to add attributes in Cost Objects via Data Bridge?

Hi everyone,
I need your help. I want to know if is possible to add attributes via Data Bridge in Cost Objects tables like the country or address of a customer?
Thanks for all.
Sincerely,
Pedro Sousa

Hi,
Jef is right you need to use the different values in the "Attribute Flag" field for creating attribute hierarchy using data bridge.
For attribute Hierarchy you need to use option 12 & 15 depending on your requirement.
12 - Attribute Assignment - Used for assigning attribute to a member of the main hierarchy
15 - Attribute Hierarchy only - used for creating hierarchy within attribute hierarchy.
As mentioned by Jef for details you can refer the Data bridge user guide section 4.3.

How to acess the value in object

Hi All,
I am trying to create a table and bound the arraylist object to it.so i created a method and set value to bean variables and added the bean object to arraylist
and i created a datacontrol.The i dragged and dropped the dataHolder and created a table.when run this page its showing the object instead of value inside
the object how to acess the value inside the object here.I also pasted the table code after dragging and dropping below
public void setData() {
TempleteBean bean =new TempleteBean();
bean.setLanguage("english");
bean.setOperation("test");
dataHolder.add(bean);
<af:table rows="#{bindings.dataHolder.rangeSize}"
fetchSize="#{bindings.dataHolder.rangeSize}"
emptyText="#{bindings.dataHolder.viewable ? 'No data to display.' : 'Access Denied.'}"
var="row" rowBandingInterval="0"
value="#{bindings.dataHolder.collectionModel}"
selectedRowKeys="#{bindings.dataHolder.collectionModel.selectedRow}"
selectionListener="#{bindings.dataHolder.collectionModel.makeCurrent}"
rowSelection="single" id="t1">
<af:forEach items="#{bindings.dataHolder.attributeDefs}" var="def">
<af:column headerText="#{bindings.dataHolder.labels[def.name]}"
sortable="true" sortProperty="#{def.name}" id="c1">
<af:outputText value="#{row[def.name]}" id="ot1"/>
</af:column>
</af:forEach>
</af:table>
Regards,
Smaran

Hi,
I think instead of
#{row[def.name]}
you would use
#{row.bindings.row[def.name].inputValue}
or something along this line.

How to retrieve 2 values from a table in a LOV

Hi
I'm pretty new to APEX. I try to retrieve two values from a table using a LOV. I have a table named DEBIT with then columns SITE, NAME and KEY
I want to display NAME to the user in a list. When the user select an item from the list, I want to retrieve the data of the SITE and KEY column of this item in order to launch an SQL command based on this two values.
How to retrieve thes two values whant the user chooses an item from the list ?
I apologize for my english, being french.
Regards.
Christian

Christian,
From what I understood about your requirement, you want a 'select list with submit' which displays "NAME" and based on the value selected, you want to get the corresponding values for "SITE" and "KEY" from the table.
Step 1: Create a select list with submit, say P1_MYSELECT 
Use something like this in the dynamic list of values for the select list: 
SELECT NAME display_value, NAME return_value
FROM DEBIT 
Step 2: Create a page process of type PL/SQL block. Also create 2 hidden items P1_KEY and P1_SITE. 
In the PL/sQL, write something like:
DECLARE
v_key DEBIT.KEY%TYPE;
v_site DEBIT.SITE%TYPE;
CURSOR v_cur_myvals IS
 SELECT KEY, SITE
 FROM DEBIT
 WHERE NAME = :P1_MYSELECT;
BEGIN
OPEN v_cur_myvals;
LOOP
 FETCH v_cur_myvals
 INTO v_key,v_site;
 EXIT WHEN v_cur_myvals%NOTFOUND;
:P1_KEY := v_key;
:P1_SITE := v_site;
END LOOP;
CLOSE v_cur_myvals;
END; 
Then you can use these values for whatever purpose you need to.
Hope this helps.

How to get attribute values from one view to another

HI all,
Thx in Advance..
I have 2 view like v1,v2.In v1 i used one attribute values from "get single attribute" method.And i need the same values in v2 screen.For this i did in v1 outbound plugs , i mentioned the parameter name . How can i get the same values in v2.

Hi chandru ,
you said you declare the parameters in the Outbound Plug of V1. now go to view V2 inbound plug Tab and creat one inbound plug
double click on the plug name .it will navigate you to the event handeler method . Now add the outbound parameter variables in the
parameters
For example : V1firing the navigation plug
a type string " defined in parameter
wd_this->fire_out_to_view2_plg(
    a =      'ABCD'                           " string
you can retrive the value freely in v2 inbound event handeler
a type string " defined in parameter
*   set single attribute
    lo_el_context->set_attribute(
      name = `TEXT`
      value = a )." here you will get the 'ABCD'.
