Modifying coding in Oracle Objects

Is there any way like to remove the specific repeated lines from the oracle objects like Function,Procedures and Packages?.For examples my certain packages are composed of more than 10000 lines of code which contains lot of dbms_output.put_line statements with different parameters.I want to remove all such statements from a specific objects with a single shot.Pls suggest.
Regards

Updating source code from the data dictionary views is not allowed, nor supported. You can perform a CTAS plus decode functions from the user_source if you want and perform the operation on the newly created table. But either way this cannot be directly taken back from here to the data dictionary tables, you will have to create some sort of formatted spool from this table to have the object recreated by means of the regular command CREATE OR REPLACE ...

Oracle Object Table Type

I have an application that I would like to map bc4j to a object type hierarchy in the database. From reading previous otn threads I'm under the impression that Domains are not used for Oracle Table Types, just for columns based on oracle types. The thread later goes on to say that for the base type (person_typ) I would map a entity object to the table(person_table) mapped to the base type. To map all the sub-types I would create new entity objects and have PersonEO subclassed into StudentEO and EmployeeEO.
I have done this and it's unclear to me when I subclass PersonEO as StudentEO how do I declare that StudentEO is of oracle object type student_typ?
I'm also having problems with inserting data into the base entity obect. Here's code:
PersonVOImpl personVo = am.getPersonVO();
PersonVORowImpl row = (PersonVORowImpl)personVo.createRow();
personVo.insertRow(row);
row.setName("Mark");
row.setPhone("911");
am.getTransaction().commit();
personVo.executeQuery();
while (personVo.hasNext()){
PersonVORowImpl personRow = (PersonVORowImpl)personVo.next();
The data gets comitted to the db correctly but when the code hits personVo.executeQuery() I get the following error:
oracle.jbo.domain.DataCreationException: JBO-25009: Cannot create an object of type:oracle.sql.STRUCT with value:Mark

Am I coding this correctly? I'm using jdev9032 for this. Are there any examples out there on how to correctly use bc4j with oracle object type tables?
Thanks in advance!

ARE ORACLE OBJECTS ALWAYS STORED IN UPPERCASE

Are the oracle objects always stored in Capital letters?
Say ,for example If I create a table as 'Table A' , It gets stored in the USER_TAB_VIEWS as TABLE A !! Is there a way to get it back as 'Table A'

..Is there any way to do it..Yes, as I indicated, use double quotes.
I am modifying an application that worked on SQL Server and hence forced to
use mixed caseI'm not sure that follows. Unless of course the app has database objects whose only difference is the use of CamelCase, e.g. tables called TableA and Tablea and (why not?) tableA. If the names are unique in a case insensitive mode then I think you are better off using Oracle's default naming convention.
But you know what you are doing, and if you think that using ...
SELECT * FROM "CamelCase"
SELECT * FROM user_tables
WHERE table_name = 'CamelCase'
/... is a lesser world of pain than ...
SELECT * FROM camelcase
SELECT * FROM user_tables
WHERE table_name = 'CAMELCASE'
/... then do go ahead.

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?
Regards,
Peter

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

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

Performance of mapping Oracle objects to Java classes

Hi,
By retrieving some test data from Oracle database in a Java application, I compared the traditional JDBC/RDBMS solution to JPublisher-generated-classes/Oracle-object-tables solution. The underlaying Oracle database and the client environment was the same in both tests. Although the table schemas were different, they represented the same data.
It seems that the traditional JDBC/RDBMS solution is much faster. Is this a reality or did I make a mistake somewhere?
BR,
Timo

I am also facing performance overhead when using Jpub generated
classes for the object types.
I am using 817 jdbc and jpub but my database is 816. I have seen
that following statements each take around 2-3 seconds to
execute. Is there any communication between driver and database
to resolve the object type ?
Please help.

How to use Oracle objects in java code

Hi all!
I'm reading an xls and i need to fill me oracle objects with java code:
OBJECT_NAME OBJECT_TYPE
LETTURA_OBJ TYPE
LETTURA_OBJ TYPE BODY
In the past weeks i've been using both java code into oracle and oracle objects, but new i need to write those objects with data i read with java, anybody can help me?
I know that the easiest work around would be to put the data i read from the excel file into a table and then fill the oracle objects, but now i want to learn how to write directly those objects with a command like the following one:
a sample of the code i'm tryng to write:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED REPORT."Manage_Excel_ASMBS" AS
import java.io.*;
import java.io.IOException;
import jxl.*;

How to get the users list that can Add/Remove or modify Vendors in Oracle?

How to get the users list that can Add/Remove or modify Vendors in Oracle?
I need to generate a report like name and responsibility. Thanks

That query gives the Supplier information.
But what i would be needing is to find out the USERS in oracle who can Add/Modify or Remove Vendors.
I assume it should be based on the Responsibility.

Use of Complex Oracle Object with JDBC

How can I use Oracle Object(or PL/Sql type) with JDBC
I have a structure of record with some attributes and table of another attribute.
My types are defined as follows !
<code>
CREATE TYPE EMPLOYEE_GRADES AS TABLE OF VARCHAR2(50)
CREATE TYPE EMPLOYEES AS OBJECT(EmpName VARCHAR2(50), EmpGrades Employee_Grades)
</code>
My custom object might have the following structure (or should it be different)
<code>
public class EmpColl implements CustomDatum, CustomDatumFactory
-- other stuff ----
/* fields */
public String empName;
public Collection empNos;
</code>
I want to pass an variable of type EMPLOYEES to an procedure.
Thanx in Advance
Chetan
[email protected]

<code>
CREATE TYPE EMPLOYEE_GRADES AS TABLE OF VARCHAR2(50)
CREATE TYPE EMPLOYEES AS OBJECT(EmpName VARCHAR2(50), EmpGrades Employee_Grades)
</code>The easiest is to use JPublisher (which comes with the SQLJ distribution).
Say:
jpub -user=username/password -sql=EMPLOYEES:Employees,EMPLOYEE_GRADES:EmployeeGrades
You will get (among others) the Java files Employees.java and EmployeeGrade.java. Go ahead, compile and use them.
Look in [Oracle Home]/sqlj/demo/jpub for a number of additional examples, and in the JPublisher User's Guide for background info.
The next (9.2) release of JPublisher will also provide some support for accessing legacy PL/SQL types from Java.

Oracle Objects and Domains in Java Server Pages

We have defined this object in a Oracle 816 Enterprise:
CREATE TYPE DESCRIPTOR AS OBJECT
( ID VARCHAR2(30),
DESCRIPTOR VARCHAR2(80))
create TYPE descriptor_table AS VARRAY(30) of DESCRIPTOR
create table foo_test
(foo_test_id varchar2(10),
descrip descriptor_TABLE )
ALTER TABLE foo_test
ADD CONSTRAINT BIBL_test_PK PRIMARY KEY (foo_test_id)
then we have created in JDeveloper 3.1 an Entity (footest) object and a Domain (DescriptorDom) for the type DESCRIPTOR; then set the type of attribute descript to mypackage.DescriptorDom
After that, we created a JavaServer Page as follows:
<jsp:useBean class="oracle.jbo.html.databeans.JSRowSetBrowser" id="abean" scope="request" >
<% abean.setShowCurrentRow(true); abean.setVisibleRows(10); abean.setShowRecordNumbers(true); abean.setReleaseApplicationResources(false); abean.setDisplayAttributes("FooTestId,Descrip"); abean.initialize(pageContext,"ot_logics_LogicsModule.FooTestView");
abean.render();%>
</jsp:useBean>
The execution of JSP shows the error:

Hi,
It looks like this might be a bug. I am going to use the information you supplied to file a bug so our QA team can investigate.
We have had problems with arrays of structs, but hope to have them fixed with our next release.

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.

Oracle Object Views Jdeveloper compatibility

Our application has been designed OOAD and documented in UML. We mapped the UML class diagrams to relational tables and created Oracle object views on top of these tables. From these views we can now generate C++ code with OTT. However, trying to access these views from JDeveloper gives us some problems. Specifically, if an object type defined by "CREATE TYPE xxx AS OBJECT" has a REF column somewhere inside it, there seems to be very little support for this in JDeveloper 10g. Our example is a country with numerous provinces. A provice type has a reference to the country type it falls in. Trying to make a GUI to maintain the provinces gives us no way to select a country to make the REF column from. In JDeveloper, when using the object view to create a maintenance GUI, we see the reference to the country in binary form. Typically we would want to select the country from a drop-down box containing country names instead of binary references. Can someone please point me to documentation describing how to do this or explain here. Thank you in advance.

Not sure if this will be helpful for you, but maybe a better approach for your Java project will be to use TopLink to map your Java objects directly to the relational schema using TopLink's meet-in-the-middle capabilities.
This way you won't need to work with the Object views in the database.
More on TopLink here:
http://www.oracle.com/technology/products/ias/toplink/index.html
Some demos of the mapping capabilities are here:
http://www.oracle.com/technology/products/ias/toplink/mwdemos/index.html
TopLink is very well integrated with JDeveloper 10.1.2

Oracle object cols and inserts

hi,
i have a type defined as follows
create type foo
a number(10),
b number(10),
c date, d date);
now i use this in a table as follows
create table test
foo_obj foo default foo(-1, -1, sysdate, sysdate) not null,
foo_name varchar2(100) not null
now what im really interested in is when i do
an insert id like to specify only some of
the values for a given obj
aka
insert into test(foo_obj, foo_name)
values (foo_obj.a(10), 'test')
so the rest of the values for that obj
come from the defaults specified..
ive been unable to find examples for the above method in the 8i docs & any help here
on the correct syntax with an example would
help enormously

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...

Oracle object, nested table on a subtype

Hello,
Is it possible to have a nested table on a subtype? If it is, can someone help me?
Here is what I need help for:
I have a supertype WORK, that have:
multivalued attribute ADDRESS
a attribute NAME, also the primary key
The subtype is called EMPLOYEE, that have:
multivalued attribute SPECIALTY
a attribute NAME
a attribute SSN
So far have I got:
//* The supertype *//
create or replace type ADRESS_TP as object(
ADRESS varchar2(50));
create or replace type ADRESSTP as table of ADRESS_TP;
create or replace WORK_TP as object(
NAME varchar2(30),
ADRESS ADRESSTP)
NOT FINAL;
create table WORK_TBL of WORK_TP(
Primary key(NAME))
nested table ADRESS store as NT_ADR(
(Primary key(nested_table_id, ADRESS))
organization index compress);
//* The subtype *//
create or replace type SPECIALTY_TP as object(
ADRESS varchar2(50));
create or replace type SPECIALTYTP as table of SPECIALTY_TP;
create or replace EMPLOYEE_TP under work_tp(
NAME varchar2(30),
SSN number)
FINAL;
The multivalued attribute SPECIALTYTP has to be declared in WORK_TBL have I been told, but how can I do that?
I'm using oracle 9i

I'm not really sure what your problem is. In future please be specific about what it is you are trying to do and what it is that is not working. If it's an error please give us the error message and number. It's not the behaviour you are expecting please describe what it does. If it's that you simply don't understand please say what you don't understand.
I go on like this because the code you have posted is somewhat confusing. The Oracle object-oriented implementation is not quite complete so that makes it hard for people who know OO but don't know Oracle. Whereas most of us who know Oracle aren't expert in OO. Also, I think you should be slightly more inventive in your names: there's so many things called ADRESS it's easy to get them tangled up.
Anyway, here's my guess at what I think your problem is....

Help on accessing Oracle object !

Hi,
Looking for a help in accessing oracle object using JDBC. I've the following object defined in Oracle.
TYPE ty_ctg_prod AS OBJECT(
PROD VARCHAR2(40 ),
NODE_ID NUMBER ,
CTG_ID NUMBER );
TYPE ctg_PROD_ary AS VARRAY (50) OF ty_ctg_PROD;
The procedure out parameter is returning :
x_ctg_prod_ary OUT ctg_prod_ary
Do I need to use a OracleTypes.STRUCT API Or oracle.sql.ARRAY to access data in this scenario.
Any pointers will be highly appreciated.
Thanks,
Shamik

// Get the object1 value from the second column col_object1
            oracle.sql.STRUCT object1 = (oracle.sql.STRUCT)collabstatement.getObject(2);
            // Get the object1 values from each row
            Object[] object1Values = object1.getAttributes();
            // Get the first value of object1, which is a string
            String str = (String)object1Values[0];
            // Get the second value of object1, which is of the type object2
            oracle.sql.STRUCT object2 = (oracle.sql.STRUCT)object1Values[1];
            // Get the values of object2
            Object object2Values[] = object2.getAttributes();
            str = (String)object2Values[0];
            BigDecimal num = (BigDecimal)object2Values[1];you can also use :oracle.sql.Datum[] attrs = oracleSTRUCT.getOracleAttributes();more info :
