WPF Binding XML in Oracle
Hi,there,I'm using WPF Binding a xml file which stored in Oracle,My question is:is there a way to Bind XML to WPF control directly? If it has,do this way as useful as Bind a data instance?
Thanks
You not given that much info...but anyway
does the following help?

Binding XML to java types generated using Oracle Class Gen
Hi,
how can you bind an XML to the java types generated using the class gen provided byOracle.
I am using oracle 9i production. as part of my design, i have to read an xml input in my java class and use the contents to create some records and send a response xml back.
The latter part of i can do as the java types provide setter methods to set the data and conversion to xml.
Jaxb can be using to bind xml to java datatypes but its not supported in Oracle9i.
What are the alternatives for achieving the same?
Thanks
AshwinHi Ashwin,
This is a bit outside my area of expertise, but I did run an older version of TopLink in the Oracle database java VM a few years back so I'll base my advice on that. Hopefully other forum members can correct me if I steer you wrong.
First you will need to set up your XML environment:
I believe the Oracle 9i database includes a JDK 1.3 VM. You will first need to determine if the VM includes any JAXP APIs. I believe there is an SQL query that allows you to query the classes available in the VM. First check if javax.xml.parsers.DocumentBuilderFactory is present.
If the JAXP APIs are already present in the database you will need to do the following. First load the class javax.xml.namespace.QName into the database. You can extract this from xmlparserv2.jar or from Suns Java Web Service Developer Pack jax-qname.jar. Then you will need to load the JAXB APIs. You can load xml.jar or jaxb-api.jar from Sun's JWSDP.
If the JAXP APIs are not present you will need to load the 10.1.3 version of the XDK jars (these are shipped with the 10.1.3 TopLink install). Load xmlparserv2.jar and xml.jar into the database.
Second you will need to setup your TopLink environment:
Load toplink.jar into the database. If the JAXP APIs were already present and you didn't load the 10.1.3 XDK jars into the database you will need to set the following System property.
toplink.xml.platform=oracle.toplink.platform.xml.jaxp.JAXPPlatform-Blaise -
Just trying to clarify some issues as I try and learn about XML, and specifically how it integrates into the DB.
1 - Is there a way with Oracle tools for me to get an XSD of an existing 9i relational schema? We are not currently using the XML DB, but our middleware developers would like to have an up to date XSD to use for their internal mapping.
2 - Is there any way that I can keep that XSD up-to-date automatically, so I get a new one whenever the schema gets updated?
3 - If I wanted to investigate storing XML docs within the DB in native XML format, I need to have an XML DB, correct? Is this DB construct maintained seperatelly from my "normal" relational schema? or are they kept in sync by Oracle?
I know these may all be real basic questions, but as I said, I'm new to XML and Oracle. I am reading as much as I can, but there are a lot of docs out there.
Thanks,
MikeHi
1. On my opinion such a tool doesn't exists. Some parts can be implemented elsewhere, but not as described by you... e.g. with XSU if you specify the parameter "withschema" the XSD of the executed statement is generated. Another example is to use DBMS_METADATA to dump the data dictionary in XML (but not XSD, of course you could write your own XSLT to do this transformation...).
2. -
3. If you use XSD-based tables the XSD and the relational model are stored separately in the data dictionary. Therefore if you change the XSD you have to drop/create the XSD-based table... no schema evolution yet.

How to store data from xml in oracle database
Hello All
Could anyone tell me ways of storing XML in Oracle and whats the best one in terms of performance issues.
any URL to this q/s would be great.
thanks
kedarBen,
The following link as some information regarding DOM API and XSQL.
http://asktom.oracle.com/pls/ask/f?p=4950:8:2923508047773696280::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:17309127931717
For XML DB, you may want to create an XMLSchema and build a table off the schema definition. Then use WEBDAV to load the xml into a folder (ie object table) Once the xml is in the database you could build a view for a relational look at the data.
Example from XMLDB Techical White Paper doc.
create or replace view PURCHASEORDER_MASTER_VIEW
(reference, requestor, userid, costcenter,...)
as select extractValue(Value(p),'/PurchaseOrder/Reference'),
extractValue(value(p),'/PurchaseOrder/Requestor'),
extractValue(value(p),'/PurchaseOrder/User'),
extractValue(value(p),'/PurchaseOrder/CostCenter'),...
from PURCHASEORDER p -
XML in Oracle 9i (best method to return a xml file from a table query)
Hello.
What is the best method to query a table, or set of tables (that will return thousands of rows) using xml in oracle? (best performance)
I'm currently using DBMS_XMLGen, is there a better method ?I think, if your talking about generating XML, that you should use XMLElement, XMLForest, etc. to create your XML.
Lets assume that you base is relational data, then maybe the following great example will give you an idea how to do it : Re: Generate XML Schema from oracle tables
As michaels pointed out (did you read the link/ URL given?), the general expectancy is that the packages will be less and less important. So also maintenance wise the XMLElement, etc way will be the best, also for the future, maintainable method. -

Ramashankar SahuAs I recall from my 8i days (it's been many years), the only way to do this is to install the XML XDK. From http://www.oracle.com/technology/tech/xml/xdk/xdk_java.html, it says "The Oracle9i versions of the XDK can also be used to build applications designed to interface with Oracle8i databases." I had thought the 10g version could do that as well but I'm not seeing it now.
Since XMLType was not part of 8i, you will need to use PL/SQL to take your Select statement results and build them into a DOMDocument structure.
Hope that helps. -
Fault handling policy for a process in the fault-binding.xml
Can I specify a fault handling policy for a specific process using fault handling framework 10.1.3.3?
<process faultPolicy="DefaultPolicy"/>
I cannot specify the name of the process according to the xsd :(
Can this be achieved?
I have a two different partner links in different processes having the same name. If I add the partner link to the fault-binding.xml what would be the result?
Note: I cannot use bpel.xml to specify the fault policies as of now.The fault policy bindings file does not allow you to specify a specific fault policy for an individual processes. You can only do this for all BPEL processes (eg: process Level) or at finer grained levels such as partner link levels.
You might be able to use the partner link level for any services that call the process in which you wnat to error handle (eg: Process C needs to be error handled. Process A and B call C so for the partner link names for invoking C could have the fault policy defined for them). Therefore any faults returned from C could propagate back to process A / B and be handled within by the policy outside of Process C. Obviously if this apporach was used you would not want to use process level definitions as C would continue to use this.
If the partner links were of the same name, they should both be handled by the fault policy that is defined withiin the Fault policy (e.g Partner Link level definitions)
An approach that can be used is to specify the fault policy within the bpel.xml file. The information would be added as follows:
</partnerLinkBindings>
<!-- Start of Definition-->
<faultPolicyBindings>
<process faultPolicy="AProcessFaultPolicy"/>
<partnerLink faultPolicy="APartnerLinnkPolicy">
<name>insertSSN_dbAdapter</name>
<name>Another_Adapter</name>
</partnerLink>
</faultPolicyBindings>
<!-- End of Definition -->
</BPELProcess>
</BPELSuitcase>
However, I noted you said you were unable to do this. I wasn't sure if this was for technical/governamce reasons or knowledge reasons (unsure where to place to the details.
Hope that helps and does not confuse matters

Generating multi-level xml in oracle
Hi,
I want to create a multi-level XML structure from oracle, is there a way?
Presently oracle provides DBMS_XMLQUERY and XMLGEN package to generated XML structure given a query. But the structure so generated is of single level. That is say I use
select XMLGEN.getXML('select * from employees') from dual;
the output is
<EMPLOYEE>
<ROW num="1">
<NAME>Mark</NAME>
<TEL>451-638191</TEL>
</ROW>
</EMPLOYEE>
That I call a single level output.
To create a multiple level XML I went in for object type in oracle. But the problem with this is that if I want to have multiple children for a single parent then object types fail. The structure below is not possible with object type.
<EMPLOYEE>
<ROW num="1">
<NAME>Mark</NAME>
<CONTACT>
<ROW>
<RESIDENCE>
<ADDRESS>
<ROW>
Fifth Avenue, New York
</ROW>
</ADDRESS>
<TEL>
<ROW>451-638191</ROW>
<ROW>451-638192</ROW>
<ROW>451-638193</ROW>

<ROW>452-638193</ROW>
</TEL>
</RESIDENCE>
</ROW>
</CONTACT>
</ROW>
</EMPLOYEE>
Then I tried nested tables. Here one needs to create an object type to create a table type. One cannot create a table type out of another table type. So that leavs me with 2 levels
object type
used by
table type
used by
table.
Presently to generated a multi-level output as shown above I'm using cursors and build it in a clob variable.
Is there any other way that one can build a multi-level structure. Or is there a build in package that comes with orace 8i (and higher).
Regards,
Milton.Milton,
I was able to generate hierarchical XML from Oracle using object views and XML-SQL Utility (XSU).
Here is a simplified version of my OR schema:
/* Physical spec object */
create or replace type physical_specifications_object as object (
physical_specifications_id number(15),
page_count number(10),
product_id number(10),
four_color_count number(10),
two_color_count number(10),
table_count number(10),
binding_type varchar2(100),
height varchar2(20),
width varchar2(20)
/* Market object */
create or replace type market_object as object (
market_id number(15),
master_class_name varchar2(50),
market_name varchar2(100),
market_type varchar2(100),
market_description varchar2(500),
level_rank varchar2(15),
market_code varchar2(100),
product_id number(10)
/* List of markets */
create or replace type market_table as table of market_object;
/* Market object view */
create or replace view market_object_view of market_object
with object identifier (market_id) as
select mkt.market_id,
class.master_class_name,
mkt.market_name,
mkt.market_type,
mkt.market_description,
prod_mkt.level_rank,
mkt.market_code,
p.product_id
from market mkt,
product p,
product_market prod_mkt,
master_class class
where p.product_id = prod_mkt.product_id
and prod_mkt.market_id = mkt.market_id
and mkt.master_class_id = class.master_class_id(+);
/* Feature object */
create or replace type product_feature_object as object (
feature_id number(15),
feature_text varchar2(3500),
feature_type varchar2(100)
/* List of features */
create or replace type product_feature_table as table of product_feature_object;
/* Product object */
create or replace type product_object as object (
product_id number(10),
title varchar2(150),
media_type varchar2(20),
standard_number varchar2(100),
physical_specifications physical_specifications_object,
markets market_table,
product_features product_feature_table
/* Product object view */
create or replace view product_object_view of product_object
with object identifier (product_id) as
select p.product_id,
p.title,
p.media_type,
p.standard_number,
physical_specifications_object(spec.physical_specifications_id,
spec.page_count,
spec.product_id,
spec.four_color_count,
spec.two_color_count,
spec.table_count,
spec.binding_type,
spec.height,
spec.width),
cast(multiset(select *
from market_object_view mkt
where mkt.product_id(+) = p.product_id) as market_table) as markets,
cast(multiset(select f.feature_id, f.feature_text, f.feature_type
from feature f
where f.product_id = p.product_id) as product_feature_table) as product_features
from product p,
physical_specifications spec
where p.product_id = spec.product_id(+)
The objective is to generate XML for a product list with all the product subelements. The simple query "select * from product_object_view" when fed to the XML-SQL utility generates multi-level SQL. Note that Oracle 8i allows up to two level collection nesting in object types. Oracle 9i removes this limitation.

Hi,
I want to create a multi-level XML structure from oracle, is there a way?
Presently oracle provides DBMS_XMLQUERY and XMLGEN package to generated XML structure given a query. But the structure so generated is of single level. That is say I use
select XMLGEN.getXML('select * from employees') from dual;
the output is
<EMPLOYEE>
<ROW num="1">
<NAME>Mark</NAME>
<TEL>451-638191</TEL>
</ROW>
</EMPLOYEE>
That I call a single level output.
To create a multiple level XML I went in for object type in oracle. But the problem with this is that if I want to have multiple children for a single parent then object types fail. The structure below is not possible with object type.
<EMPLOYEE>
<ROW num="1">
<NAME>Mark</NAME>
<CONTACT>
<ROW>
<RESIDENCE>
<ADDRESS>
<ROW>
Fifth Avenue, New York
</ROW>
</ADDRESS>
<TEL>
<ROW>451-638191</ROW>
<ROW>451-638192</ROW>
<ROW>451-638193</ROW>
</TEL>
</RESIDENCE>

<ROW>452-638193</ROW>
</TEL>
</RESIDENCE>
</ROW>
</CONTACT>
</ROW>
</EMPLOYEE>
Then I tried nested tables. Here one needs to create an object type to create a table type. One cannot create a table type out of another table type. So that leavs me with 2 levels
object type
used by
table type
used by
table.
Presently to generated a multi-level output as shown above I'm using cursors and build it in a clob variable.
Is there any other way that one can build a multi-level structure. Or is there a build in package that comes with orace 8i (and higher).

Good Morning!
I wanted to insert some xml Data into my Orcale XML DB:
First of all I registered 2 Schemas required for the XML, like this:
Begin
DBMS_XMLSCHEMA.registerSchema(
schemaURL => 'Mailpiece_Processing/oif_dtypes',
schemaDoc => bfilename('XML_TEST','oif_dtypes.xsd'));
End;
then Created a table:
Create table XML_default auf XMLType
then inserted XML like this:
insert into xml_default
values
XMLTYPE
Bfilename ('XML_TEST', 'Test.xml'),
nls_charset_id('AL32UTF8'
Now to my question: Oracle is offering more than one possebility to save XML into its DB. If I import XML like this, is it called CLOB Storage or object relational?
Thanks in advance
runkelHi ,
I can only give u a few examples here but for the full sytanx and features of this powerful feature u may have to refer to some documentation online or read a book on XML within Oracle Database.
Let me try a few examples here
1) To extract the data from XML document an SQL plus command is available in XML DB. This feature is available from 10G onwards
example : select xmlelement(name,ename) from emp
Output will look like
<NAME>SMITH </NAME>
<NAME> JOHN </NAME>
<NAME> JONES </NAME>
2) CREATE TABLE FAMILIES (F_ID NUMBER(3), F_XML XMLTYPE);
insert into families values(1,xmltype('<XML.....>'));
or
insert into families values(1,''<XML>......' ));
Hope this helps !!!

Hi Gurus,
I would like to learn about XML in Oracle database 10g.
Where can I get examples and supporting documents?
Thanks and Regards,

Here are few links ->

Generating multi-level XML in Oracle 8i using XML-SQL utility
Oracle 8i has a limitation when it comes to the object types. Only one-level nesting of collection is allowed. Oracle 9i apparently removes this limitation.
I am trying to generate XML for a hierarchical (conceptually) structure. To do that I am using XML-SQL utility (XSU) running agains an object view build on top of the relational data. The problem is the limit to onelevels of colelction nesting. Oracle 8i gives you a way to create a view with more levels of nesting by using references (REF). The problem is that when XSU runs agains a view with the references, it inserts the references into the XML document (instead of dereferencing them).
Is there a way to generate XML with Oracle 8i with more than two levels of collection nesting?
Thank you.

Where are the data-binding frameworks for Oracle Objects?
Oracle offers a few different options for data-binding frameworks to Oracle relational data. Amongst them they include TopLink and the Oracle Application Development Framework (ADF)in JDeveloper 10G. J2EE also offers the EJB standard framework. Both of the Oracle data-binding frameworks appear to work well with relational data but fail miserably when one tries to work with a fully fledged Oracle Object-Relational schema. I have spend much time with ADF but have not been able to create successful bindings to Objects with nested complex objects (such as a 2-level nested object) or objects containing nested tables. TopLink will not even touch Object tables.
Have other people being more successful with this? Do we have to implement our own data binding framework? Does Oracle plan on improving these frameworks to fully support Oracle Objects?TopLink Runtime supports both fully fledged OX mappings and nested complex objects. These mappings can be setup in the code.
TopLink ADF design time however currently does not have support for OX mappings.
Hope this helps, -

Trying to bind XML data and form fields
I have a fairly simple PDF - and I am trying to bind XML data to he form fields.
In the designer I can bring up the data connection and
select Global - for the binding method - and as I understand it - this will link Form Fields and XML data fields with the same name - (sounds logical to me)
but all that happens is :
I see the name of the field in the form field rahter than seeing the actual data
should I select : None as the binding or normal ....
but Normal doesnt show Anything - even after i select it .
I can't quite seem to make this work -
Any help here would be appreciated
Thanks :)This is on a stand - alone system
Using Designer ES ......
I saved the Form as an xdp form
and it seems as if all goes well until
View the data and nothing appears - or
just the names of the fields appear
