DatabaseMetaData for Oracle Object Types

I have successfully written a Java program to read a schema - i.e. Tables, Primary Keys, Imported Keys, Exported Keys & Columns - using DatabaseMetaData. However, I need to decompose Oracle Objects.
My test case is:
SQL> desc object_column_table
Name Null? Type
ID NUMBER(11)
TYP OBJ_COL_TYP
SQL> desc obj_col_typ
Name Null? Type
VC VARCHAR2(255)
NUM NUMBER(11)
DT DATE
CH CHAR(7)
I believe I have found the method that I require:
public void showAttributes(String schema, String typeName, String attribute)
The JavaDoc says "Retrieves a description of the given attribute of the given type for a user-defined type (UDT) that is available in the given schema and catalog."
However, this throws "java.sql.SQLException: Unsupported feature"
My driver details are:
Driver Name: Oracle JDBC driver
Version: 10.1.0.2.0
Major Version: 10
Minor Version: 1
JDBC Major Version: 10
JDBC Minor Version: 1
Connected to:
Oracle Database 10g Enterprise Edition Release 10.1.0.4.0 - Production
With the Partitioning, OLAP and Data Mining options
So, how do I decompose Oracle Objects?
Thanks in advance for your help.

reynaudj,
Try searching this forum's archives for the term "STRUCT". Perhaps also search the OTN Web site as well.
Good Luck,
Avi.

Domains for Oracle object types

When I create a domain for a certain Oracle object type there is no way to create some kind of inheritance tree (and there is no discriminator support it seems). On the database level I have several object types that extend a certain base object type. I want to do the same at the BC4J level. But unfortunately this doesn't seem possible. Is there a work-around for it? I don't mind to write a little extra code, any hints or help are appreciated.
Regards,
Peter
P.S.
It seems the object type / domain support in JDeveloper 9.0.3(.1) isn't quite up there with entities and view objects. It's not even possible to change an attribute name at the Java side using the domain dialog (it's only possible by manually editing the XML and Java files). Will JDeveloper 9.0.4 have broader support for object types / domains?

I've found a way to implement the inheritance myself, at least a start. I've noticed all custom domains for oracle object types have the static method "getCustomerDatumFactory". In this method (in the base domain class) normally an instance of the base type is returned. I've modified this method so that it returns instances of the different subtypes depending on the value of a certain column. To make this work I first have to edit the Java files of the subtypes and let them extend the base type instead of the Struct class. The factory method looks like this:
public static CustomDatumFactory getCustomDatumFactory()
    if (fac == null)
      class facClass implements CustomDatumFactory
        public CustomDatum create(Datum d, int sql_type_code) throws SQLException
          if (d != null)
            BaseType b = new BaseType(d);
            if ("subtype1".equals(b.getType())) b = new SubType1(d);
            else if ("subtype2".equals(p.getType())) b = new SubType2(d);
            else System.err.println("Unknown subtype: " + b.getType());
            return b;
          return null;
      fac = new facClass();
    return fac;
}I also tried to save several of the subtypes in the database in the attribute field (which is of the base type) using setAttribute, this seems to work out-of-the-box. It seems for now I only get this to work if the object type is saved in a column of a certain table, I can't get it to work (yet) for object type tables (see the other recent topic of mine).
Is this the correct way to implement what I want? Or is there a better way?

Getting varchar objects as "???" while using struct for oracle object type

Hi all.
I have a problem whith VARCHAR values which is returned from an oracle function. The function returns an oracle type and I get it using STRUCT. I can get all non VARCHAR values of the TYPE like NUMBER and TIME without any problem. But when I get VARCHAR values, they all come as if equal to"???". I called the database function in TOAD and everything works perfect. It seems that somewhere in between we loose the information. Has anyone encountered such a strange problem?
Part of the code look like:
CallableStatement callState = null;
          ResultSet rs = null;
          UOAReturnType result= new UOAReturnType();
          try
               callState = getConnection().prepareCall("{?=call Call.UACBS.GETREDL(?)}");
               callState.registerOutParameter(1, OracleTypes.STRUCT,"CALL.TYPE_REDL_RO");
               callState.setString(2,msisdn);
               callState.execute();
               Struct RedlRoStrct = (Struct)callState.getObject(1);
               Object[] redlRo = RedlRoStrct.getAttributes();
               Struct redlStruct = (Struct)redlRo[0];
               Object[] redl =null;
               if(redlStruct!=null){
                    redl = redlStruct.getAttributes();
                    result.setMsisdn(redl[0].toString());
                    try {
                         result.setTime(UtilDate.getDate(redl[1].toString(),dateFormat,custLocale));
                    } catch (NullPointerException e2) {
                         result.setTime(null);
                         e2.printStackTrace();
                    result.setReason(Integer.parseInt(redl[2].toString()));
                    result.setSource(redl[3].toString());
               Struct opReturnStruct = (Struct)redlRo[1];
               Object[] opReturn = opReturnStruct.getAttributes();
               result.setResultCode(Integer.parseInt(opReturn[0].toString()));
               result.setResultDescription(opReturn[1].toString());Any idea will be appreciated.
Thanks.......

Hi,
I don't think it is a java problem.You can see time and number types because the characters are digits. My guess is that it has something to do with some settings on the client. Try to have the NLS_LANG environment variable appropriately set. Also try invoking your test script from sqlplus to see if the results actually work.

Oracle Object Types vs. Table Fields

Hello, all.
I`m totally new to Oracle, and I am facing a very hard problem for me, and I would like to ask your help.
I've been working on a project which uses Oracle Object Types, from a database of a legacy system.
I did not know Oracle Objects until 5 minutes ago, so sorry If I say something stupid:
Per my understanding, a Oracle Object Type can be formed by fields like myField varchar(200)... and fields from an existing table or view.
I have a lot of objects on my system and I need to map each field and its respective table or view that compose each object.
Does anyone have a query for that? I think it should be common, but I could not find anything at google (maybe I don`t which terms use to find...)
I would be very thankful if somebody could help (save) me.
Thanks in advance.
Paulo

First, it would help if you post what you object types look like.
I'm assuming they may look something like this:
SQL> create TYPE emp_type AS OBJECT
2    (emp_id   NUMBER,
3     name VARCHAR2(20));
4 /
Type created.
SQL> create TYPE emp_tab IS TABLE OF emp_type;
2 /
Type created.
SQL> create or replace package emp_test as
2 procedure get_emps;
3 end emp_test ;
4 /
Package created.
SQL> create or replace package body emp_test as
2    employees emp_tab := emp_tab();
3    procedure get_emps as
4      g_rc sys_refcursor;
5 BEGIN
6    employees.EXTEND(2);
7    employees(1) := emp_type (1, 'John Smith');
8    employees(2) := emp_type (2, 'William Jones');
9    OPEN g_rc FOR
10    SELECT * FROM TABLE (CAST (employees AS emp_tab));
11 END get_emps ;
12 end emp_test ;
13 /
Package body created.

Working with oracle object type tables

Hi,
I've created a table which only contains Oracle object types (e.g. CREATE TABLE x OF <...>). When I create an Entity for this table using the Entity wizard, I end up with an entity with the attributes of the base object type and two special attributes REF$ (reference to the object type instance) and SYS_NC_OID$ (unique object identifier). The REF$ attribute is on the Java side of type oracle.jbo.domain.Ref and the other attribute is on the Java side a simple String.
It seems this only allows me to save objects of the base type in this table. First of all in my situation this is also impossible because the base type is not instantiable. What I do want is to save several different subtypes into this table using the BC4J custom domain mechanism. Is there any way to make this possible? I first thought I could maybe do something with the special REF$ attribute, but this doesn't seem te case. So I might need to override most of the EntityImpl methods, like doUML, remove etc. Am I right? And does anyone have any hints on how to do this?

Peter

Since you have an object table, you wouldn't use domains to achieve this. Instead, you would have a superclass and subclass entity objects, e.g., PersonEO subclassed into StudentEO and EmployeeEO.

something with the special REF$ attribute, but this
doesn't seem te case. So I might need to override
most of the EntityImpl methods, like doUML, remove
etc. Am I right? And does anyone have any hints on

If you want, you can try this by overridding EntityImpl's:
   protected StringBuffer buildDMLStatement(int operation,
      AttributeDefImpl[] allAttrs,
      AttributeDefImpl[] retCols,
      AttributeDefImpl[] retKeys,
      boolean batchMode)
and
   protected int bindDMLStatement(int operation,
      PreparedStatement stmt,
      AttributeDefImpl[] allAttrs,
      AttributeDefImpl[] retCols,
      AttributeDefImpl[] retKeys,
      HashMap retrList,
      boolean batchMode) throws SQLException
Handle the case when operation == DML_INSERT.
There, build an insert statement with substitutable row, e.g.:
INSERT INTO persons VALUES (person_t('Bob', 1234));
INSERT INTO persons VALUES (employee_t('Joe', 32456, 12, 100000));
where person_t and employee_t are database types and you are invoking the respective constructor.

My question is i m transferring this XML to a third party webservice and it does inserting into a third party application.
The problem is if you look under EnquiryAttribute tag ENQATTRIBSTRINGVALUE and ENQATTRIBTYPECODE i need this to be in lowercase.
As the xml is getting automatically generated how do i achieve this. I feel them in the uppercase is causing problems at the other end.
Any help appreciated

Use "..." delimiters in the CREATE TYPE (and in all your code that references the type).

ERD and oracle object types

Is there a good way to model oracle object types using ERD's in designer 6i. I can only figure out how to map to tables with columns of predefined datatypes (varchar2, number, date, long). I'd like to use designer to create new datatypes. Is this possible? Thanks.

Hi Wiiliam
Sorry for the late acknowledgement (i dozed off!).. Thanks for the response. So the private instance specific to a session ensure that theres no conflict between multiple requests to the same stored proc and hence no conflict of data... Great

Problem using Oracle Object Types and Arrays.

I'm currently trying to work with oracle object types in java and I'm running into some issues when trying to add an item to an array.
The basic idea is that I have a header object and a detail object (both only containing an ID and a description). Inside of my java code I'm trying to add a new detail line to the header that has been retrieved from the database.
Here's what I'm working with.
--Oracle Objects:
CREATE OR REPLACE TYPE dtl_obj AS OBJECT
    detail_id INTEGER,
    header_id INTEGER,
    detail_desc VARCHAR2(300)
CREATE TYPE dtl_tab AS TABLE OF dtl_obj;
CREATE OR REPLACE TYPE hdr_obj AS OBJECT
    header_id INTEGER,
    src VARCHAR(30),
    details dtl_tab
CREATE TYPE hdr_tab AS TABLE OF hdr_obj;
/--Java test methods
     public static void main(String[] args) throws SQLException,
               ClassNotFoundException
          // Initialize the objects
          Test t = new Test();
          t.connect(); //Connects to the database
          //The oracle connection will be accessible through t.conn
          // Create the oracle call
          String query = "{? = call get_header(?)}";
          OracleCallableStatement cs = (OracleCallableStatement) t.conn.prepareCall(query);
          cs.registerOutParameter(1, OracleTypes.ARRAY, "HDR_TAB"); //Register the out parameter and associate it with our oracle type
          int[] hdrs = { 240 }; //we just want one for testing.
          ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor(
                    "ARRAY_T", t.conn);
          oracle.sql.ARRAY oHdrs = new ARRAY(descriptor, t.conn, hdrs);
          cs.setARRAY(2, oHdrs); //Set the headers to retrieve
          // Execute the query
          cs.executeQuery();
          try
               ARRAY invArray = cs.getARRAY(1);
               // Start the retrieval process

          // Convert the current list to an ArrayList so we can easily add to it.
          ArrayList<Detail> dtlLst = new ArrayList<Detail>();
          dtlLst.addAll(java.util.Arrays.asList(hdr.getDetails().getArray()));
          // Create the new detail
          Detail dtl = new Detail();
          dtl.setDetailDesc(desc);
          // add the new detail
          dtlLst.add(dtl);
          Detail[] ies = new Detail[dtlLst.size()];
          ies = dtlLst.toArray(new Detail[0]);
          DetailTable iet = new DetailTable(ies);
          hdr.setDetails(iet);
     }I know its the addDetail method causing the issue because if I comment out the t.addDetail(inv, "new line"); call it works fine.

Oracle® Database Object-Relational Developer's Guide
Also note that object relational database design is often less performant and scalable than relational. It is not very often used in production environments.
However, the object orientated programming feature that is provided with Oracle object feature set are used and can make development and interfaces a lot easier.
So in a nutshell. Say no to ref and nested table columns. Say yes to most of the other object features. IMO of course...

Debugging Oracle Object types

Hi
I'm trying to debug a application (in 9i Release 2) using PL/SQL object types and was wondering if JDev can help.
I can see the objects, and their code, but the debugger seems unable to step into them, see local variables etc. It also incorrectly identifies code errors -- in short it appears to be using the 9i Release 1 drivers.
I've just installed version 9.0.3.2 but that hasn't helped. The release notes say helpfully that 9.0.3 can handle the drivers for 9i R2, but it won't use them!
I'm about to try the 10g preview, but I'm not feeling hopeful. Is this something I can expect to be fixed or do I have to find some other way of debugging my code?
Thanks,
Glenn.

Hi,
I also have problems debugging oracle objects. I'm running an Oracle Database Version 9.2.0.1.0 and use
JDeveloper 9.0.3 to remotely debug PL/SQL Code. The debugging works fine when I'm setting breakpoints and
step through the code.
But I seem to be unable to list the value of variables of
object types and variables of nested table types. And of course I cannot set conditional breakpoints on variables that have an Oracle object type. If I try 10g, there is no improvement. The object types are not recognized as Oracle object types or nested table types, instead they are shown as $Oracle.builtin.OPAQUE
I need this feature to remotely debug procedures, that mostly use Oracle object types as parameters. Is there any possibility that I can get this feature to work? Otherwise JDeveloper is not much of a use for me when I'm debugging PL/SQL code.
Thanks,
Astrid
I provided an example, in which I create the above mentioned types and fill them with data, but where I'm unable to retrieve the values of the variables in JDeveloper:

How to return Values from Oracle Object Type to Java Class Object

Hello,
i have created an Oracle Object Types in the Database. Then i created Java classes with "jpub" of these types. Here is an example of the type.
CREATE OR REPLACE TYPE person_type AS OBJECT
ID NUMBER,
vorname VARCHAR2(30),
nachname VARCHAR2(30),
geburtstag DATE,
CONSTRUCTOR FUNCTION person_type RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_id NUMBER) RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_vorname VARCHAR2,
p_nachname VARCHAR2,
p_geburtstag DATE) RETURN SELF AS RESULT,
MEMBER FUNCTION object_exists(p_id NUMBER) RETURN BOOLEAN,
MEMBER PROCEDURE load_object(p_id NUMBER),
MEMBER PROCEDURE save_object,
MEMBER PROCEDURE insert_object,
MEMBER PROCEDURE update_object,
MEMBER PROCEDURE delete_object
MEMBER PROCEDURE load_object(p_id NUMBER) IS
BEGIN
SELECT p.id, p.vorname, p.nachname, p.geburtstag
INTO SELF.ID, SELF.vorname, self.nachname, SELF.geburtstag
FROM person p
WHERE p.id = p_id;
END;
My problem is, that if i use the member function "load_object" from my java app it doesnt return the selected values to the java class and i dont know why. I use the java class like this:
PersonObjectType p = new PersonObjectType();
p.load_object(4);
There is a reocrd in the database with id = 4 and the function will execute successful. But if i try to use "p.getVorname()" i always get "NULL". Can someone tell me how to do that?
Thanks a lot.

CallableStatement =
"DECLARE
a person_type;
BEGIN
a.load_object(4);
? := a;
END;"
And register as an out parameter.

Problem Instanciating BO - No default attribute defined for the object type

Hello Experts,
I am instanciating the BO BUS2038 to ZBUS2038 and when I click in u201Cto implementedu201D and follow u201Cto releasedu201D the message No default attribute defined for the object type is appearing!
Can anybody help, please?

Hello everyone,
it appears to me, that no one has a clue about the "default attribute" and is widely guessing what can be done about that.
I feel deeply sorry for that, Marcos.
At first: You don't really need to care about the missing default attribute. If it's missing, the object's instance key will be used instead. Skip the warning message.
Secondly: The default attribute is used to display the instance within the "Object links & Attachments" under the work item preview when using the SAP Business Workflow.
Thirdly: You can select any existing attribute of your business object type to be the default attribute, by navigating to the "Basic data" (it's the heat-icon within the object builder), use tab "Defaults" and use the Input Help on the field "Attribute".
There you'll go.
Best wishes,
Florin

Microsoft OLE DB Provider for Oracle: Data type is not supported.

I got the error:
Microsoft OLE DB Provider for Oracle: Data type is not supported.
Shortly after upgrading from Oracle 8 to Oracle 9. I was advised to download more up to date oracle drivers, but I was wondering if there was a way to tell what version of the 'OLE DB Provider for Oracle' is already at. Is there a command I can use via SQL Plus or something?

I have found Microsoft ODBC for Oracle to be more stable than the Microsoft OLEDB for Oracle driver. I have also found both Microsoft ODBC and OLEDB drivers to be more stable than the drivers from Oracle.
You could always get the latest MDAC (Microsoft Data Access Components) from Microsoft's MSDN Download site and then get the ODAC (Oracle Data Access Components) from Oracle's OTN Download site. ODAC requires MDAC. And ODAC has the latest drivers.
I suppose it would help to have the latest patches for your Oracle client software too. Maybe Oracle MetaLink would have these?
It may even help to have the latest service pack for Visual Studio 6 (Visual C++ 6 and Visual Basic 6) too.

Identification number for the object type H

Hello:
There is an infotype thats allow me to enter an identification number for the object type external person (H) in the training and event management module (PE)?. I was checking in the configuration and I dont find the solution for this issue.
I ask to myself if is necessary to create one infotype for this purpose?
I will appreciate your colaboration and the answer.
Thanks

Hi Vijay:
It is something similar to the infotipo 185 of object person type of the module PA. I need an identification document for external person (example: driver license)

Class type not defined for this object type

Hi Friends,
Could u please guide me ?..We have a requirement to extract some data from classification system.
This is related with class type 023 - Batch
I want to use the following parameters in CTBW.
basis datasource :Z_BATCH_ATTR
class type : 023
object table :MCHA
Datasource type : ATTR
I am getting an error "Class type not defined for this object type" when i enter the above entries in CTBW.
The only way I'm being able to make this work is changing object table from MCHA to MCH1.
This solution does not fit me bacause MCH1 table dont have Plant as Key, and I need it.
Do you know what should I do to solve this?
Thanks in advance

Hi,
I believe we have to use the list of standard "Basis DataSource", as I'm also stuck with the same issue. Let me know what Basis Data source you selected in this case.
As I'm trying to extract Batch attributes from "AUSP" Table.
I have given class type= 023
Obj Table= AUSP
But not sure which "basis datasource" I need to select.
Thanks,
Satish

Invoking stored procedure that returns array(oracle object type) as output

Hi,
We have stored procedures which returns arrays(oracle type) as an output, can anyone shed some light on how to map those arrays using JPA annotations? I tried using jdbcTypeName but i was getting wrong type or argument error, your help is very much appreciated. Below is the code snippet.
JPA Class:
import java.io.Serializable;
import java.sql.Array;
import java.util.List;
import javax.persistence.Entity;
import javax.persistence.Id;
import org.eclipse.persistence.annotations.Direction;
import org.eclipse.persistence.annotations.NamedStoredProcedureQuery;
import org.eclipse.persistence.annotations.StoredProcedureParameter;
* The persistent class for the MessagePublish database table.
@Entity
@NamedStoredProcedureQuery(name="GetTeamMembersDetails",
     procedureName="team_emp_maintenance_pkg.get_user_team_roles",
     resultClass=TeamMembersDetails.class,
     returnsResultSet=true,
     parameters={
     @StoredProcedureParameter(queryParameter="userId",name="I_USER_ID",direction=Direction.IN,type=Long.class),
     @StoredProcedureParameter(queryParameter="employeeId",name="I_EMPLOYEEID",direction=Direction.IN,type=Long.class),
     @StoredProcedureParameter(queryParameter="TEAMMEMBERSDETAILSOT",name="O_TEAM_ROLES",direction=Direction.OUT,jdbcTypeName="OBJ_TEAM_ROLES"),
     @StoredProcedureParameter(queryParameter="debugMode",name="I_DEBUGMODE",direction=Direction.IN,type=Long.class)
public class TeamMembersDetails implements Serializable {
     private static final long serialVersionUID = 1L;
@Id
     private long userId;
     private List<TeamMembersDetailsOT> teamMembersDetailsOT;
     public void setTeamMembersDetailsOT(List<TeamMembersDetailsOT> teamMembersDetailsOT) {
          this.teamMembersDetailsOT = teamMembersDetailsOT;
     public List<TeamMembersDetailsOT> getTeamMembersDetailsOT() {
          return teamMembersDetailsOT;
Procedure
PROCEDURE get_user_team_roles (
i_user_id IN ue_user.user_id%TYPE
, o_team_roles OUT OBJ_TEAM_ROLES_ARRAY
, i_debugmode IN NUMBER :=0)
AS
OBJ_TEAM_ROLES_ARRAY contains create or replace TYPE OBJ_TEAM_ROLES_ARRAY AS TABLE OF OBJ_TEAM_ROLES;
TeamMembersDetailsOT contains the same attributes defined in the OBJ_TEAM_ROLES.

A few things.
You are not using a JDBC Array type in your procedure, you are using a PLSQL TABLE type. An Array type would be a VARRAY in Oracle. EclipseLink supports both VARRAY and TABLE types, but TABLE types are more complex as Oracle JDBC does not support them, they must be wrapped in a corresponding VARRAY type. I assume your OBJ_TEAM_ROLES is also not an OBJECT TYPE but a PLSQL RECORD type, this has the same issue.
Your procedure does not return a result set, so "returnsResultSet=true" should be "returnsResultSet=false".
In general I would recommend you change your stored procedure to just return a select from a table using an OUT CURSOR, that is the easiest way to return data from an Oracle stored procedure.
If you must use the PLSQL types, then you will need to create wrapper VARRAY and OBJECT TYPEs. In EclipseLink you must use a PLSQLStoredProcedureCall to access these using the code API, there is not annotation support. Or you could create your own wrapper stored procedure that converts the PLSQL types to OBJECT TYPEs, and call the wrapper stored procedure.
To map to Oracle VARRAY and OBJECT TYPEs the JDBC Array and Struct types are used, these are supported using EclipseLink ObjectRelationalDataTypeDescriptor and mappings. These must be defined through the code API, as there is currently no annotation support.
I could not find any good examples or doc on this, your best source of example is the EclipseLink test cases in SVN,
