Oracle collection

Is it possible to call a PL/SQL procedure from Java with a PL/SQL table as a parameter?
thanx

Don't think so.... seem to remember this caused us a problem a while ago.
Our solution was to use Oracle collection types instead.

How to convert Oracle Collection(Objects) to XML dynamically?

Dear members,
As a requirement I need to pass the collection of values(typically a object or a table type) to a procedure and generate a XML file on the fly basing on these collection values.I am not sure how to do it.Can anyone please guide me on that?
Thanks

Hi,
depending on how often/how complex the programming job is:

Oracle Collections

Hi,
We have a requirement to build a procedure:
The procedure should be capable of the following:
I procedure will accept certain input parameters (Example: 4 Input parameteres).
The input varables should be capable of holding more than one value.
The procedure will also have a cursor based on some table, and this select will accept the above input parameters and will fetch the data.
If they send the input parameters in bulk how do i receive them and will pass to my cursors select.
Please help me with this, its very urgent.
Please let me know incase of any clarifications.
Thanks and Regards
Srinivas

You have not specified how you will use the input parameters in the where clause. So i make my
assumption that the input parameters will be applied at the each column in row level. Said that
you dont have to have 4 input parameters you can create a object list instead.
Below is an example to demonstrate how to do it.
following is my employee table

New with oracle collection

All,
Can any one help me in finding the difference between the below two types
create or replace type typ_custadd as object
(house_no number,
floor_number number,
street_number number,
city varchar2(30),
pin_code number
create or replace type typ_custadd as record
(house_no number,
floor_number number,
street_number number,
city varchar2(30),
pin_code number
Regards
Sikander

When you declare a type in PL/SQL, such as the record type in your example, it is only usable from PL/SQL.
If it is declared locally to a procedure or function, then it can only be used within that subprogram;
if it is declared in a package body it can only be used within that package;
if it is declared in a package header it can be used by any PL/SQL code that has execute access to the package.
In no way can it be referenced in SQL statements, even ones embedded in the PL/SQL code.
When you create an object type, or other schema-level type definitions such as nested tables,
it is usable within both SQL and PL/SQL.

this is becoming a mejor problem for me.And are you storing it as a blob?
Oracle doesn't take varchars that big.
And isn't LONG a deprecated field type for Oracle?
From the Oracle docs......
http://download-west.oracle.com/docs/cd/B13789_01/server.101/b10759/sql_elements001.htm#sthref164
Oracle strongly recommends that you convert LONG RAW columns to binary LOB (BLOB) columns. LOB columns are subject to far fewer restrictions than LONG columns. See TO_LOB for more information.

Issue with use of collection type attibutes of oracle custom objects in BC4

Hi There,
Just see the simulation, it seems to be an issue with BC4J/OC4j when we have an attribute in the view object mapped to a database column that is of type collection of custom oracle objects.
1-     I have a oracle type Quantity that is defined to contain 2 numbers
2-     I have a oracle collection QuantityList that is a collection of Quantity objects.
3-     I have a table defined as :
CREATE TABLE ANU_TEST_QUANTITYLIST
ID        NUMBER,
USR_DATA QUANTITYLIST
NESTED TABLE USR_DATA STORE AS ANU_QUANTITYLIST;4-     Now I try to select the id and usr_data column of this table through the VAnuTestQuantityList view.
5-     It throws the following exception:
## Detail 0 ##
java.io.NotSerializableException: oracle.jdbc.driver.T4CConnection
     at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1075)
     at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1369)
     at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1341)
     at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1284)
     at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1073)

I try using the "Business components from tables" wizard to create a new EO, VO, and AM related to the ANU_TEST_QUANTITYLIST and it works fine for me. You'll see that JDeveloper creates you a custom Quantitylist domain object as part of this process.
If you are making programmatic use of the oracle.sql.STRUCT then you will see this error in three-tier.
Use the oracle.jbo.domain.Struct instead.

Oracle Designer Collection problem

Hi all,
this is my first post in this forum, but I've been using it a lot and I'd like to thank everyone that have always helped me through their posts.
Now I have come to a problem to which I can't find a solution...
My problem is the following:
My goal is to import a data model. To do this I have to create certain objects in Oracle Designer, prior to importing the model itself. The reason for this is that if this certain object isn't created, the import itself fails on a given table.
More objectively, the object I'm trying to create in the "Server model" in the "Oracle Collection Type" is a VARRAY of 999999 elements of RAW(2000).
When I try to create this object, I get the following error:
Message
RME-00209: Current activity has outstanding violations
Cause
Could not 'commit' the data because of outstanding
data integrity violations.
Action
Examine violations, fix the invalid data, and try again.

Examine other reported errors for specific details.

This error is on Designer 9.0.2.10 and on Oracle 9.2.0.7 database
If I try the same thing on Designer 10.1.2.4 and on Oracle 10.2.0.1, I get the following:

If anyone could shed some light on this, it would be much appreciated.
Best regards to all of you,
Filipe

Hi Michael. Thank you for your reply.
Nevertheless, I think that what you say is not correct since I can create a VARRAY of NUMBER datatype; the only thing I can't create is a VARRAY of RAW datatype.
Can you, or anyone, comment on this?
Thank you.

Filipe

Pass a Collection of multi-column records from JAVA to Plsql

Hi,
I need to pass a Collection of multi-column records(say Employee Id, Employee Name and Employee Address) from a JAVA application to an Oracle package/stored procedure
for data processing and updates.
I initially thought of using a pl/sql table as an input parameter, but then I came to know that a pl/sql table can have ONLY one column and an index (can be a String in
the case of an Associative Array). Please let me know if my understanding is wrong here.
I then thought of using a PL/SQL table with a RECORD type as an element. But, I came across a documentation that says that, Oracle JDBC does not support RAW, DATE, and PL/SQL RECORD as element types.
Could you please let me know how I can pass multi-column records from JAVA to an Oracle Stored procedure as an input parameter? Millions of rows would be sent by the JAVA program to the Oracle Stored procedure.
Any help will be highly appreciated.
Regards,
Sunil.

There are several examples in the " Working with Oracle Collections" from the "JDBC Developer's Guide and Reference". You can either use a Map to create Java objects that are created with the Oracle objects data or the generic oracle.sql.STRUCT interface.

On making call to Oracle procedures from Java, Value becomes null on oracle

We are using some user defined Oracle data types in my Java/J2EE application
and some of them are Oracle collections(ex. VARRAY).
We are making a call to Procedures/Functions from Java, there are some
parameters of user defined data types declared in the
procedures/functions, from java the values are properly setting to these
user defined data type parameters and sending to Procedures.
We are not getting any exception at Java side and Oracle side and values
are becoming blank/null at oracle procedure side for the parameters of
user defined data types.
But when do the count of collection of user defined data type then it is
properly giving the size of collection(VARRAY).
When we are trying to read the values from the collection(VARRAY) it is
giving blank/null value and there is no exception.
Please let me know if you have any suggestion on this?

user7671994 wrote:

Dyanamic sampling and statistics collection

HI all,
im a newbie and i have a question. please correct me if im wrong too.
The documentation I studied specifies that Dyanmic sampling collects the statistics of the objects. im not sure during query execution or while an auto job.
i also read that starting from 10g , Oracle collects stats for objects as a job (using dbms_stats package). the job is scheduled for new or stale objects , running between 10 pm and 6 am.
if oracle already runs a job for collecting stats what is dynamic sampling good for.
Please fill me in . can some body also explaing the query optimizer components.
thanks in advance.
Dev

Assume stats are collected every day at 02:00. Beginning at 08:00 users start making changes. By 11:45 the stats may not bear a close relationship to what was collected the previous morning.
I thought the explanation in the docs was clear. What doc are you reading (please post the link).

How to disable automatic statistics collections on tables

Hi
I am using Oracle 10g and we have few tables which are frequently truncated and news rows added to it. Oracle automatically analyzes the table by some means which collects statistics of the table but at the wrong time(when the table is empty). This makes my query to do a full table scan rather using indexes since the statistics was collected when the table was empty.Could any one please let me know how to disable the automatic statistics collection feature of Oracle?
Cheers

Oracle?
First of all I think it's important that you understand why Oracle collects statistics on these tables: Because it considers the statistics of the object to be missing or stale. So if you just disable the statistics gathering on these tables then you won't have statistics at all or outdated statistics.
So as said by the previous posts you should gather the statistics manually yourself anyway. If you do so right after loading the data into the truncated table, you don't need to disable the automatic statistics gathering as it only processes objects that are stale or don't have statistics at all.
If you still think that you need to disable it there are several ways to accomplish it:
As already mentioned, for particular objects you can lock the statistics using DBMS_STATS.LOCK_TABLE_STATS, or for a complete schema using DBMS_STATS.LOCK_SCHEMA_STATS. Then these statistics won't be touched by the automatic gathering job. You still can gather statistics using the FORCE=>true option of the GATHER__STATS procedures.
If you want to change the automatic gathering job that it only gathers statistics on objects owned by Oracle (data dictionary, AWR etc.), then you can do so by calling DBMS_STATS.SET_PARAM('AUTOSTATS_TARGET', 'ORACLE'). This is the recommended method.
If you disable the schedule job as mentioned in the documentation by calling DBMS_SCHEDULER.DISABLE('GATHER_STATS_JOB') then no statistics at all will be gathered automatically, causing your data dictionary statistics to be become stale over time, which could lead to suboptimal performance of queries on the data dictionary.
All this applies to Oracle 10.2, some of the features mentioned might not be available in Oracle 10.1 (as you haven't mentioned your version of 10g).

Increase Scope of Custom variables in Oracle JVM

We on our project are facing the following problem, any suggestions to work around this would be appreciated :
We our using Oracle 9i JVM for development
Our Sample problem flow is as follows :
A package PKG1 has three procedures PROC1/PROC2/PROC3
A java class JC1 is invoked by a procedure PROC1 - JC1 is running under oracle JVM.
JC1 does the task of mapping a custom user defined java object to an oracle collection and invokes a procedure PROC2 (we are using thin client connection object in JAVA by means of simple JDBC calls to connect to the database.) which takes the oracle collection as input parameter and does processing over it.
A procedure PROC3 does the task of calling PROC1 and then tries to access global variables defined in the package set by PROC2 , which comes out as a failed operation throwing the error as:
ORA-06531: Reference to uninitialized collection
The reason for the above behavior is : In the parent oracle session invoked by PROC1 the class JC1 opens another child database session for PROC2 and thus values set in the child thread are not visible to the parent.
Required support: Is there a means for setting up of some property in ORACLE or Java which can enforce the JAVA CLASS to use its parent / invoking oracle session or if there is any other approach to overcome the above situation.

Anand,
I believe the Java in the Oracle Database forum is more appropriate for your question.
You said:
The reason for the above behavior is the parent oracle session opens
another child database session
How do you do this? And why? And what evidence makes you certain that this is the problem?
Good Luck,
Avi.

Issue in passing Oracle User Defined Types to PL SQL from Websphere Applica

HI,
I am facing an issue when trying to pass Oracle collection object(User Defined Types) from Java to PL SQL. The issue happens inside J2EE application which is running inside Websphere Application Server 6.x. My database is Oracle 10g and i am using ojdbc1.4.jar as thin driver.
The issue is that when i pass the Oracle Object from java side, the attribute values of the collection objects at the Oracle PL SQL side is coming as empty. I have tried the same java code in a standalone application and it works fine. The issue happens only when the application is running inside WAS.
Anybody has any idea how to pass Oracle User Defined Types from WAS 6.x server to Oracle PL SQL?

Hi
I am using WebLogic 8.14 & Oracle 9i with thin JDBC driver.
Our application needs to perform the same DB operation for every item in a Java Collection. I cannot acheive the required performance using the standard Prepare & Execute loop and so I am looking to push the whole collection to Oracle in a single invocation of a Stored Procedure and then loop on the database.
Summary of Approach:
In the Oracle database, we have defined a Object Type :
CREATE OR REPLACE
TYPE MYTYPE AS OBJECT
TxnId VARCHAR2(40),
Target VARCHAR2(20),
Source VARCHAR2(20),
Param1 VARCHAR2(2048),
Param2 VARCHAR2(2048),
Param3 VARCHAR2(2048),
Param4 VARCHAR2(2048),
Param5 VARCHAR2(2048),
and we have defined a collection of these as:
CREATE OR REPLACE
TYPE MYTYPE_COLLECTION AS VARRAY (100) OF MYTYPE
There is a stored procedure which takes one of these collections as an input parameter and I need to invoke these from within my code.
I am having major problems when I attempt to get the ArrayDescriptor etc to allow me to create an Array to pass to the stored procedure. I think this is because the underlying Oracle connection is wrapped by WebLogic.
Has anyone managed to pass an array to an Oracle Stored procedure on a pooled DB connection?
Thanks
AndyHi. Here's what I suggest: First please get the JDBC you want to work in a
small standalone program that uses the Oracle thin driver directly. Once
that works, show me the JDBC code, and I will see what translation if
any is needed to make it work with WLS. Will your code be running in
WebLogic, or in an external client talking to WebLogic?
Also, have you tried the executeBatch() methods to see if you can
get the performance you want via batches?
