How to present a relational table os object

I have tables that came from Progress. The convert process converted their columns of type array to individual columns in oracle. Their data server copes with this, but I have been asked if it is possible to see a more familiar view for other uses.
EG. I now have...(only 1 row shown)
Table
=====
col1 (number) (unique column) = 1
col2 varchar(10) = 'fred'
col3 varchar(10) = 'sometext'
col4##1 varchar(10) = 'tom'
col4##2 varchar(10) = 'dick'
col4##3 varchar(10) = 'harry'
col5 varchar(10) = 'sometext2'
col6 varchar(10) = 'sometext3'
col7##1 number = 7
col7##2 number = 14
col7##3 number = 21
What do I need to do/setup to be able to query - preferably by an updateable view - the data, so that a query something like
"select col1,col2,col3,col4[2],col5,col6,col7[3] from table where col1 = 1;" would return a result of
1 fred sometext dick sometext2 sometext3 21
or
"select col1,col2,col3,col4[1],col4[2],col5,col6 from table where col1 = 1;" results in
1 fred sometext tom dick sometext2 sometext3
The array sizes are known and rarely if ever changed.
Any help appreciated. Version 8.1.7.4 on HPUX 11 64bit

Oops - the select would be against a VIEW (or object table?) and not the relational table, obviously.

Converting Relational Tables to Object Views

We have extra information stored for each
field in a table. We call these Vertical
Tables:
rowid primary key - ties to normal tab
column_name "" - ties to column in ""
text_value the value if text
reliability rating for level of accuracy...
date of entry
Yes there are normal tables that the applications also access if they just need the value of the columns.
So I want to take this to object views. This way, while oracle is learning how to alter objects, we can still maintain our data and old application while converting to the use of objects.
I thought the best solution would be Type(s) based on the orignal data type. A generic type, text65_t could be created to hold every column that is less than 65 characters long:
CREATE TYPE text65_t AS OBJECT
WITH OBJECT IDENTIFIER(row_id) AS
row_id VARCHAR2(30),
value VARCHAR2(65),
reliability NUMBER(1,0),
doe DATE
A view can easily be created of this. The
mapping is one to one.
My problem is the next level. How can I build another view on top of text65_t, integer_t, date_t... that ties all of the
vertical rows back into a normal relational table or object.

How not to rotate relative to the object?

hi,
currently i am rotating transformgroups like this:
       Transform3D currenttrans = new Transform3D();
       objTrans.getTransform(currenttrans);
       Vector3f currentVector = new Vector3f();
       currenttrans.get(currentVector);
       currenttrans.setTranslation(new Vector3f(0,0,0));
       objTrans.setTransform(currenttrans);
       Transform3D rotateclockwise = new Transform3D();
       rotateclockwise.rotX(-Math.PI/10);
       currenttrans.mul(rotateclockwise);
       currenttrans.setTranslation(currentVector);
       objTrans.setTransform(currenttrans);But that does not feel right. It always rotates relative to the object. But I want to rotate it relative to the universe (or to my view).
That means I for example: I want to be able to rotate the object like a head that looks to the right, no matter what its current state is. This means in my example: If the "head" is currently "looking down" then it should still look down at the same angle after I rotated it to the right.
I hope u understand (its hard to explain without pictures).

To find where any node is relative to the rest of the universe you can use it's getLocalToVworld method. That should save you a bit of extraneous calculation at least.

ABAP OO: how to pass a internal table with objects as a method parameter

Hello all,
I have a class "ZCL_VEHICLE", this class contains the attribute WHEELS.
This attribute contains objects of the class ZCL_WHEEL.
(definition: data WHEELS TYPE TABLE OF REF TO zcl_wheel.).
I now need a method that gives this table back (as return or export parameter). How can I define a parameter for this method that will contain this table?
Thanks for the help.
Best regards,
Wim

Hi Wim
Excuse me! I understood you wanted to define it in a program, not in a class.
You can define your type into CLASS (use the same statament: go to TYPES (there's a pushbotton on status gui).
TYPES: MY_WHEELS TYPE TABLE OF REF TO .....
Now you can use this type to create a parameter like that, but you can use that type for an object of class defined as PRIVATE.
Infact if your object is public, you'll use it in a your program, so you'll probably have to define a variable like the type defined in the class.
It shouldn't make sense to define the same type for two times or more (one in the class, the others in each program uses your class). So you should define your type in dictionary (all abap object could use it).
If you think to have to use your class in few program (perhaps in olny one), you shuold consider to create your class as local class.

How do I pass a table of objects to global classes (creatd in class buildr)

Using local classes where I type everything in SE38, this is done using the following:
METHOD some_method
IMPORTING table_of_objects TYPE TABLE OF REF TO z_class
However, I don't know how to do this in the class builder. In the PARAMETER subscreen of the methods tab, the type column only has TYPE, LIKE, and TYPE REF TO.
Please help. Thanks!
Kyle

You can also define the PUBLIC table type in the PUBLIC section. Use this table type as the type for your parameter.
In class ZCLASS, create a public table type. use Go to > Public Section and create the type, like:
types: ty_t_zclass type standard table of ref to zclass.
In your other method, use this type to define the parameter (or attributes)
IT_ZCLASS_OBJ IMPORTING TYPE ZCLASS=>TY_T_ZCLASS

HOW to know the related tables in EBS source

Hi
My user wants to get the same columns like EBS front end in the OBIEE. What is best way to know what table belongs to the column in EBS Front end .
Thanks

Hello,
In Oracle EBS from the "Help"/"Record History" will give you the table/view name, when you can find here then use following menu functions (this will also give you additional information, like column details).
1) Open Forms
2) Click on Help/Diagnostics/Examine (*you might have to enter the APPS password at this point)
3) Change "Block" to "System"
4) Change "Field" to "Last_query"
Help Menu> Diagnostics> Examine. The system will ask for the password which is usually “apps”
And once you have you view or table info .. search in http://etrm.oracle.com/ for its base table information.
Hope this helps. Pls mark if it does.
Thanks,

How to reimport relational table objects into RPD physical layer...

I am new to OBIEE. I am not sure how to reimport relational database tables into physical layer whenever the base database table structure changes.
How do I configure the ODBC or OCI 10G/11G connections on my computer so I can reimport objects into RPD on remote server.
I would appreciate it if you can give step by step instructions
Thanks in advance.

Hello -
You can re-import a table to the Physical Layer the exact same way that you would import the table for the first time:
1) Click File > Import > From Database...
2) Select your data source connections
3) Choose your table you wish to reimport
The system will warn you that you will overwrite the existing table and may lose information. The information you would lose is any discrepencies in the physical layer that are no longer existing in the actual database table. However, logical columns will NOT be overwritten.
Alternately, if it is a minor change to the table (say a column name change, or one additional column added), you can also manually add the column
1) Right Click on the already imported table in the presentation layer and select New Object > Physical Column...
2) Name the column and provide the proper data type
The column now exists in the physical layer and will be properly associated with the new column in the database, assuming the same column name was attributed. You WILL have to drag this new column forward to the logical layer and presentation layer, as this will not be automatically done.
I hope this answers your question. If you found this helpful, please assign points!

Printing out results in case of object-relational table (Oracle)

I have made a table with this structure:
CREATE OR REPLACE TYPE Boat AS OBJECT(
Name varchar2(30),
Ident number,
CREATE OR REPLACE TYPE Type_boats AS TABLE OF Boat;
CREATE TABLE HOUSE(
Name varchar2(40),
MB Type_boats)
NESTED TABLE MB store as P_Boat;
INSERT INTO House VALUES ('Name',Type_boats(Boat('Boat1', 1)));
I am using java to print out all the results by calling a procedure.

CREATE OR REPLACE Package.body House_boats AS
PROCEDURE add(everything works here) AS LANGUAGE JAVA
Name House_boats.add(...)
PROCEDURE results_view AS LANGUAGE JAVA
Name House_boats.resuts_view();
END House_boats;
However, I am not able to get Results.view working in case of object-relation table. This is how I do it in the situation of relational table.
CALL House_boats.results_view();
House_boats.java file which is loaded using LOADJAVA:

There are several things wrong with your code and methodology
1. The code you posted won't even compile because there are several syntax issues.
2. You are trying to use/test Java in the database BEFORE you get the code working outside the DB
3. Your code is not using collections in JDBC properly
I suggest that you use a different, proven approach to developing Java code for use in the DB
1. Use SIMPLE examples and then build on them. In this case that means don't add collections to the example until ALL other aspects of the app work properly.
2. Create and test the Java code OUTSIDE of the database. It is MUCH easier to work outside the database and there are many more tools to help you (e.g. NetBeans, debuggers, DBMS_OUTPUT windows, etc). Trying to debug Java code after you have already loaded it into the DB is too difficult. I'm not aware of anyone, even at the expert level, that develops that way.
3. When using complex functionality like collections first read the Oracle documentation (JDBC Developer Guide and Java Developer's Guide). Those docs have examples that are known to work.
http://docs.oracle.com/cd/B28359_01/java.111/b31225/chfive.htm
http://docs.oracle.com/cd/E11882_01/java.112/e16548/oraarr.htm#sthref583
The main issue with your example is #3 above; you are not using collections properly:
String value = rset.getString(i);
A collection is NOT a string so why would you expect that to work for a nested table?
A collection needs to be treated like a collection. You can even treat the collection as a separate result set. Create your code outside the database and use the debugger in NetBeans (or other) on this replacement code for your 'printResults' method:
static void printResults (ResultSet rset) throws SQLException {
    try {
       ResultSetMetaData meta = rset.getMetaData();
       while (rset.next()) {
           ResultSet rs = rset.getArray(2).getResultSet();
           rs.next();
           String ndx = rs.getString(1);
           Struct struct = (Struct) rs.getObject(2);
           System.out.println(struct.getSQLTypeName());
           Object [] oa = struct.getAttributes();
           for (int j = 0; j < oa.length; j++) {
              System.out.println(oa[j]);
    } catch (SQLException e) {
       System.err.println(e.getMessage());
That code ONLY deals with column 2 which is the nested table. It gets that collection as a new resultset ('rs'). Then it gets the contents of that nested table as an array of objects and prints out the attributes of those objects so you can see them.
Step through the above code in a debugger so you can SEE what is happening. NetBeans also lets you enter expressions such as 'rs' in an evaluation window so you can dynamically try the different methods to see what they do for you.
Until you get you code working outside the database don't even bother trying to load it into the DB and create a Java stored procedure.
Since your current issue has nothing to do with this forum I suggest that you mark this thread ANSWERED and repost it in the JDBC forum if you need further help with this issue.
https://forums.oracle.com/community/developer/english/java/database_connectivity
When you repost you can include a link to this current thread if you want. Once your Java code is actually working then try the Java Stored procedure examples in the Java Developer's Guide doc linked above.
At the point you have any issues that relate to Java stored procedures then you should post them in the SQL and PL/SQL forum

How to set different relations to object Primary UID and to another UID?

I am a quite experienced in data modeling, but not too much in SQLDM. The problem is I can not find in SQL DM a feature that allows to set up two different relations between two objects with different set of parent-child attributes for the relations. E.g. object A has PK attribute A1 and attribute A2 as UID. When I am trying to create 1:M relation to another object B it always generates attribute A1 in the object B, although my intention is to create two different relations with different "parent" attributes A1 and A2. The relation property -> Attributes window does not allow to edit attributes. It's not a pure theoretical question. In the real word e.g. ISO_CURRENCY table has two unique identifiers for the currency - alpha and numeric and some data have FKs to first or second UID. Could someone give a clue how to handle that in SQL DM, please?

Thanks a lot David,
I read the thread you pointed carefully. IMHO the ODM problem in the light of this discussion is that the ODM Logical Model is not a Logical Model :) The classical ERD model which ODM is used for logical modeling is not supposed to reflect the way which the relation is implemented in the database model which can be not relational in general. But ODM creates "attribute of relation" in the child table demonstrating the relational database approach. So we have Logical Model as Relational Model with some kind of restrictions like I mentioned as the question for the thread.
IMHO It'd be more abstract from the database model if the ODM logical model relation implementation is not shown in the logical model and it can be altered on the relational model generation stage (default mode could be FK generation based on the object PK).

REF to an object in a relational table

Hi!
I try do create a DB for TINs made of triangles. Because of the topology a triangles ist made of three edges and each edge is made of two nodes. The nodes contain the geometry (x,y,z coordinates).
I created object types for each element.
In order to fasten the request of geometry data I build Spatial objects, too.
My tables look like the following
CREATE OR REPLACE TYPE node_objtyp AS OBJECT (
node_Id NUMBER(10,0),
xValue NUMBER(7,3),
yValue NUMBER(7,3),
zValue NUMBER(7,3)
CREATE TABLE nodes_reltab(
node_Id NUMBER(10,0),
node_Ref node_objtyp,
node_Shape mdsys.sdo_geometry
CREATE OR REPLACE TYPE edge_objtyp AS OBJECT (
edge_Id NUMBER(10,0),
from_Node_Ref REF node_objtyp,
to_Node_Ref REF node_objtyp,
is_Fold NUMBER(1,0)
CREATE TABLE edges_reltab(
edge_Id NUMBER(10,0),
edge_Ref edge_objtyp,
edge_Shape mdsys.sdo_geometry
How do I insert data into edges_reltab if from_Node_Ref and to_Node_Ref in edge_objtyp should refer to two existing node_objtyps in nodes_reltab node_Ref column??
I tried
INSERT INTO edges_reltab VALUES(
1,
edge_objtyp(
1,
(SELECT REF(n)
FROM (
SELECT node_ref
FROM nodes_reltab
WHERE node_Id = 1
)n
(SELECT REF(n)
FROM (
SELECT node_ref
FROM nodes_reltab
WHERE node_Id = 2
)n
0
mdsys.sdo_geometry(
3002,
NULL,
NULL,
mdsys.sdo_elem_info_array(1,2,1),
mdsys.sdo_ordinate_array(
2,4,0,
3,4,0,
2,4,0
But just got a ORA-00904 error!
In my first DB I used object tables. It worked fine, but it was impossible to create an Spatial index an these tables. So I've been forced to use relational tables.
Thank you for your help!
Joerg

Hi Joerg
It is only possible to use REF with object tables and object views.
Creating an object view over the relational table will probably not solve your problem (see error ORA-22979).
Therefore, since you are using a relational model, you should use a foreign key.

How a relational table stores data

Hi,
Can anyone please tell me how a relational table stores data internally? I mean what happens internally when we insert a new row into table? Please give me link of PDFs that I needed to go through. What I want is to be able to write a code for Relational objects such as table. What kind of preparation is needed for this?
Please give your answer in detail. You may send me direct email at [email protected]

MULTIPLE ROWS IN OBJECT RELATIONAL TABLE, HELP

Hi,
Here is my problem explanation. Please help. I have created an object type address, and a relational table called employee. One of the column in employee table is based on the type address. Now suppose I want to have 5 differrent addresses for a perticular employee how can I have it stored? The empno is the primary key .Here is the data strucure
address( line1 varchar2(30),city varchar2(30), state varchar2(20), zip varchar2(13))
employee
(empno number,
name varchar2(60),
emp_add address)
Thanks
Feroz

Well you could give your employees a nested table of addresses. But as William said, you really ought to use relational tables for this situation.
I haven't yet come across a compelling argument for using Types instead of tables for data storage, and there are lots of drawbacks. Duplication of data is just one.
Cheers, APC

Mix object tables with relational tables?

Hallo,
is it possible to mix object tables with relational tables in one database?
I didn't succeed in assigning a foreign key from a relational table to an object table.
Is this only working with column objects in relational tables?

Hi
is it possible to mix object tables with relational tables in one database?
Every database contains both types of tables. So, it is basically not a problem.
I didn't succeed in assigning a foreign key from a relational table to an object table.
Is this only working with column objects in relational tables?It would be interesting to know how you tried... e.g. what error you get... Here an example (executed on 11.1).
SQL> create or replace type tt as object ( n number );
2 /
SQL> create table ot of tt (constraint ot_pk primary key (n));
SQL> create table rt (n number, constraint rt_ot_fk foreign key (n) references ot (n));
SQL> insert into ot values (tt(1));
SQL> insert into rt values (1);
SQL> insert into rt values (2);
insert into rt values (2)
ERROR at line 1:

How to define join in physical layer between cube and relational table

Hi
I have a aggregated data in essbase cube. I want to supplement the information in the cube with data from relational source.
I read article http://community.altiusconsulting.com/blogs/altiustechblog/archive/2008/10/24/are-essbase-and-oracle-bi-enterprise-edition-obiee-a-match-made-in-heaven.aspx which describes how to do it.
From this article I gather that I have to define a complex join between the cube imported from essbase to my relational table in physical layer.
But when I use Join Manager I am only able to define jooin between tables from relation source but not with the imported cube.
In My case I am trying to join risk dimension in the cube based on risk_type_code (Gen3 member) with risk_type_code in relation table dt_risk_type.
How can I create this join?
Regards
Dhwaj

Hi
This has worked the BI server has joined the member from the oracle database to cube. So Now for risk type id defined in the cube I can view the risk type code and risk type name from the relational db.
But now if I want to find aggregated risk amount against a risk type id it brings back nothing. If I remove the join in the logical model then I get correct values. Is there a way by which I can combine phsical cube with relational model and still get the aggregated values in the cube?
I have changed the column risk amount to be sum in place of aggr_external both in logical and phsical model.

Dhwaj
