Alter types object in oracle 8.0.6

Hi ,
I have one type object having name 'reftype' which is depend on preticular table
Now I have to modify this type defination without deleting its depend object or table .
I have tried to alter or add new attribute method but its giving below error ..
"ORA - 02303 cannot drop or replace a type with type or table dependent(s)"
Can some one help me?
Thanks & Regards,
Shrirang Mokashi

EXECUTE IMMEDIATE was new in 8i. In prior versions, you might use the DBMS_SQL supplied package instead.

Using union query to return a value to Oracle Type object in a view

Hi All,
I am using type objects inside a view to fetch data. For a particular type, in select statement when i use a "union all", it is throwing oracle error ora-03001 unimplemented feature. But it is working fine when it contains only select statement inside the type.
Thanks in advance

OCI 22303 exception - Pass object to type Record in oracle procedure

Recently i had my first encounter with ODP.NET and Oracle. I'm developing a a datalayer that can access a stored procedure on an Oracle database.
The problem i'm having is the following:
I'm using this method to pass my parameters to the procedure: http://www.codeproject.com/KB/cs/CustomObject_Oracle.aspx
I have also attempted this approach:
http://developergeeks.com/article/48/3-steps-to-implement-oracle-udt-in-odpnet
I always get the message (litteraly):
Oracle.DataAccess.Client.OracleException: OCI-22303: type &quote;PAC$WEBSHOP_PROCS"."CUSTOMER_IN_RECTYPE" not found.
It sounds weird to me, but what are the &quotes doing here in the error message I see?
Some code i use:
OracleParameter objParam = new OracleParameter
OracleDbType = OracleDbType.Object,
Direction = ParameterDirection.Input,
ParameterName = "PAC$WEBSHOP_PROCS.P_CUSTOMER_IN",
UdtTypeName = "PAC$WEBSHOP_PROCS.WEBSHOP_PROCS.CUSTOMER_IN_RECTYPE",
Value = card
The information i have about the Oracle procedure:
CREATE OR REPLACE PACKAGE PAC$WEBSHOP_PROCS IS
TYPE CUSTOMER_IN_RECTYPE IS RECORD
(CUS_STO_IDENTIFIER NUMBER(2)
,CUS_IDENTIFIER NUMBER(6)
,CH_IDENTIFIER NUMBER(2)
,CH_CARD_VERSION NUMBER(1)
PROCEDURE PRC$WS_VALIDATE_CARD
(P_CUSTOMER_IN IN PAC$WEBSHOP_PROCS.CUSTOMER_IN_RECTYPE
,P_RETURN_CODE IN OUT NUMBER
Any help to cover my problem would be greatly appreciated.
Thx

The only way to call it as is would be via an anonymous plsql block, where you create the record type inside the block. Interacting with the block via ODP would be limited to scalar values.
Here's a PLSQL example just to demonstrate. Here, v1 and v2 are bind variables of scalar type, which you'd setup/bind via ODP instead of the SQL prompt as I did, but I thought this might keep things simpler for the example.
The other choice would be to write a wrapper procedure that takes type OBJECT that you can call from ODP, and inside that procedure convert them to/from RECORD and call the original procedure.
Hope it helps,

Alter type to add a member function

Hello,
I have Oracle 9i r2 and I really nedd to add a member function into an Object that is associated to other.
My Object spec is this:
TYPE CM_CTRL_CM AS OBJECT
lo_Ent_CM CM_Ent_CM,
member function IniEntCM(self in out CM_Ctrl_CM) return integer
I do this to add a member function:
alter type CM_Ctrl_CM add member function FijDatCM(ao_DatCM in CM_DatCM) return integer cascade ;
And as the result I get the nex the Object Spec:
TYPE CM_CTRL_CM AS OBJECT
lo_Ent_CM CM_Ent_CM,
member function IniEntCM(self in out CM_Ctrl_CM) return integer
alter type CM_Ctrl_CM add member function FjDatCM(ao_DatCM in CM_DatCM) return integer cascade
As you can see, all the alter type statement is added at the end of my Object Spec wich cause a compilation error and the object get invalid.
I need to know how to add a member function. It's very important for the my project successfull.
Thanks.
Luis Silva

And as the result I get the nex the Object Spec:
TYPE CM_CTRL_CM AS OBJECT
lo_Ent_CM CM_Ent_CM,
member function IniEntCM(self in out CM_Ctrl_CM) return integer
alter type CM_Ctrl_CM add member function FjDatCM(ao_DatCM in CM_DatCM) >> return integer cascade

SQL types over PLSQL types while using Oracle Applications adapter in BPEL

Use SQL types over PL/SQL types while using Oracle Applications adapter
in BPEL/ ESB
This document will be focusing on Oracle Applications adapter. However Database adapter is much like OA adapter (even OA adapter uses DB Adapter), so the readers who are interested to explore DB adapters, can relate things with this document and go further as well.
Some Guidelines for writing PL/SQL APIs for OA Adapter
As we know when we create a partner link from the OA adapter wizard it sometimes writes some wrapper script supportive to the OA Adapter WSDL which contains below
* Object type for PL/SQL RECORD
* Nested table of the given type for PL/SQL TABLE. For example, the nested table of NUMBER.
* INTEGER substituted for PL/SQL BOOLEAN
* Wrapper Script for converting above three set of data types . (PLSQL to SQL and SQL to PLSQL conversion functions)
In runtime this wrapper script for converting PL/SQL to SQL and SQL to PL/SQL is an extra overhead.
So the first advice would be to avoid the use of the below as parameters of PLSQL API being called by OA Adapter.
* PL/SQL RECORD
* PL/SQL TABLE. For example, the nested table of NUMBER.
* PL/SQL BOOLEAN
In other way we can say we should try to use only SQL data types in arguments if we are planning to call any PL/SQL API from the OA Adapter.
If the requirement is to use a table or record uses the Object type. In place of BOOLEAN better to use VARCHAR or INTEGER what ever fulfills your requirement. Following this guideline we can reduce a huge number of Line of codes to be run each time the adapter being called.
Generally, Oracle E-Biz standard APIs use PL/SQL record types and table types so when there is a requirement to call these API’s from OA Adapter (this is a common requirement in development), and if we directly browse the API in OA Adapter Configuration Wizard and create the partner link, again a huge number of code is written by the wizard in the wrapper script (a number of extra mapping of fields which are not being used in the interface).
In this case better would be to create an Object type with only the required fields which are being used in that call and use them as parameters for the PLSQL API.

EM10gR2 Grid Control / Change Management Pack does not support TYPE objects

I wonder any Oracle EM10gR2 Grid Control users, implementing Oracle Change Management Pack, have used it for the release and proper packages management.
Issue1 - On an EM console / Web GUI the DDL comparison and synchronization is not supported at all. Implementing it @ customer it appeared that we have to install a 10g Java Client in order to use the code comparison and sync functionalities.
Issue2 - and this is more serious - it appears that even with Java client in use, you cannot compare or sync objects related to TYPE or TYPE BODY data types. The comparison simply hangs.
Asked help from support, they mentioned an ER from 8i and logged a new ER for 10g/11g. That is surprising especially as the doc (http://download.oracle.com/docs/html/A96679_01/toc.htm) about code comparison does not exclude the TYPE objects from the supported options.
Any fellow DBA running to a same problem? What solutions & recommendations might you have?

Hi Mugunthan,

How to store java object in oracle

Hi all,
is it possible to store jva object in oracle.
I have defined myClass. It have only data fields ( no methods).
I make myClass myObject = new myClass();
How can I store this object in oracle DB.
Many thanks in advance.

1.Convert this object into stream of Bytes.
2.create a new InputStream from these Byte array.
2.Use the setBinaryStream to set the values inside the table's column.
3.Store this object as a Blob in the table (column type must be Blob).
Hope this helps.
Sudha
PS:- Somebody explained in this forum how to convert an Object into Byte array .

Is there table type object in PL/SQL?

Hi.
What I'm trying to do is, according to the some conditions, aggregate data as an object type( I am not sure that there's a similar thing)
There are 5-6 conditions. then at last join those table type object.
FYI, Here is an example
Company will give bonus to a person who meet these conditions
1. Salary is less than 1000$ - salary table
2. More than 5 persons in his family - staff table
3. gross sale is over 10000$
In PL/SQL Package, I'll get those data as an object type and join those object just like in-line query.
select emp_no
from sal_tbl , staff_tbl, sale_tbl
where sal_tbl = staff_tbl
and sal_tbl = sale_tbl
In my opinion I can get employee list who get bonus. because they meet all conditions.
Reason why bonus condition will be updated continuously. I want to make them easy to maintanence. what if I need to add new conditions. Just add a new procedure that calculate new result and pass as an table type object.
select emp_no
from sal_tbl , staff_tbl, sale_tbl, new_tbl*
where sal_tbl = staff_tbl
and sal_tbl = sale_tbl
and sal_tbl = new_tbl*
Is there any thing just like what I think?
Thanks in advance

Not the best of ideas. If I'm getting what you're saying, you want to use the following approach:

7 MIN( column_value ) into minVal

10 /
PL/SQL procedure successfully completed.A collection of objects resides in (non-sharable and expensive) PL/SQL memory. Running SQL, requires the PL/SQL engine copying the data to the SQL engine into a structure and format that the SQL engine will understand.
This is slow. This is expensive. This does not scale.
It makes little sense to copy data from the very fast and hot and good and scalable db buffer cache into an expensive memory structure in the PGA and then run SQLs against that.
> Reason why bonus condition will be updated continuously. I want to make them easy
to maintanence. what if I need to add new conditions. Just add a new procedure that
calculate new result and pass as an table type object.
The way I read your SQL, your new_tbl* requires dynamic SQL. Which means you also need to dynamically cater for the correct column names to join on, to filter on, and to select from.
Also not the best of ideas. Dynamic SQL like that requires a lot of code to deal correctly with bind variables. Lot of exception handling as there can easily be run-time errors as the code itself that is executed in turn creates new dynamic code to execute.
If this is to be truly dynamic, then one approach would be that each rule needs to be executable as a SQL or PL/SQL block. Each rule needs to have an input like an employee number. Each rule needs to returns a boolean like value, saying whether the rule has passed or failed.
Only when all the rules have been passed, can the bonus be allocated.
This will deal fine with the "dynamic rule" requirement. Performance wise and scalability wise.. it may not be the best of ideas. 10 dynamic and very slow and expensive rules, could very well be rewritten as a one very fast and very cheap static SQL statement.
Anyway, the dynamic rule approach can look something like the following:
SQL> create or replace type TBonusRule is object

PL/SQL rules can in a similar fashion be subclassed from the base/asbtract class. And rules can be persisted in a table too.
But even though I did this example to illustrate just how flexible Oracle can be, I would personally think hard before using the above approach myself.
Why?
Because rules 1 and 2 resulted in two SQLs being fired. A single SQL could have done the job.
2 SQLs were used for a single employee. I can use a single SQL to find ALL employees that matches the rule criteria.
So... not very scalable and not very fast.

Implementing Objects in Oracle Forms

Am preparing for my Forms exam and would really appreciate it if anybody knew where i could get online info/resource with examples on how to implement and manage objects in Oracle forms. Have downloaded 10g and the associated documentation about 200Mb which has got everything except detailed info on Oracle Forms and implementing objects.
Thanks
Gus

Thank you Rosario, not exactly what i was looking for at this moment but certainly something i will use as i will want to use PJCs, a very valuable link, thank you again :)
What i want to find out is there a similar type of guide to implementing object tables with relational tables in a simple form, as i have given it a try and haven't really got anywhere, so a step wise guide would be great.
Cheers

Alter type to increase varray size

I have the following:
CREATE OR REPLACE TYPE idvarray is varray(10) of INTEGER
CREATE TABLE event_availability_map
, event_id_list idvarray
I would like to increase the size of idvarray, how can I do this?

Stephen,
With pre-10g releases, you can declare the varray to be of a large size to accomodate future growth. Oracle allocates storage based on actually used sizes.
With 10g release, you can issue 'alter type' statement to raise the varray size limit (http://download-west.oracle.com/docs/cd/B13789_01/appdev.101/b10799/adobjcol.htm#sthref310).
