Hi,
I want to store xml file. which method is best by storing path or XML type.
Please advise.
Thanks,

If you do, then you need to store it using something like a CLOB. However, when you need this CLOB as a XML structure, it needs to be parsed and a XMTLTYPE structure needs to be created. This can be quite expensive processing wise and impact resources and performance.
You can decide that the original format does not need to be kept and in that case store it as a XMLTYPE.
Or you can decide that you want to use both methods, at the expense of disk space, as it is warranted - and store it both as a CLOB and XMLTYPE for example.
As diskspace is relatively inexpensive these days (the least costliest of server resources), we tend to store it as both CLOB and XMLTYPE. As for auditing (even corporate governance reasons) the original format is important, and for performance dealing with a XML structure is important.

Reporting Services web service complex xml type report parameters

Hi,
I have the following xml type parameter in my request query that I use in reporting services.
<Parameter Name="accountDetails" Type="XML" xmlns:d4p1="thevalue" xmlns:i="thevalue">
<DefaultValue>
<d4p1:AccountDetailDto>
<d4p1:AccountNumber>12345</d4p1:AccountNumber>
<d4p1:AccountType>Sales</d4p1:AccountType>
</d4p1:AccountDetailDto>
</DefaultValue>
I want to know how I can assign values to the accountDetails parameter from report parameters, I've tried to call it from the dataset parameter properties but it doesn't return any values. I created Parameters!accountDetails.Value on the dataset parameters
properties and assigned it the following value: it only returns empty columns
="<AccountDetailDto><AccountNumber>"& Parameters!AccountNumber.Value &"</AccountNumber><AccountType>"& Parameters!AccountType.Value &"</AccountType></AccountDetailDto>"
You're help will be highly appreciated as I've been trying to solve this for a while now

Hi Alisa,
Perhaps I should explain my problem clearly...
This is my query request that I send to the webservice:
<Query>
<Method Name="GetPerAccountAssetAllocation" Namespace="http://tempuri.org/">
<Parameters>
<Parameter Name="accountDetails" Type="XML" xmlns:d4p1="thevalue" xmlns:i="thevalue">
<DefaultValue>
<d4p1:AccountDetailDto>
<d4p1:AccountNumber>12345</d4p1:AccountNumber>
<d4p1:AccountType>JSE</d4p1:AccountType>
</d4p1:AccountDetailDto>
</DefaultValue>
</Parameter>
</Parameters>
</Method>
<SoapAction>http://tempuri.org/IPortfolioManagementService/GetPerAccountAssetAllocation</SoapAction>
<ElementPath IgnoreNamespaces="true">*</ElementPath>
</Query>
It works well when I run it just like this, that is without specifying any parameters in the report data dialogue window or on the dataset parameters properties, it returns the values and columns correctly.
So my problem is, I need to find out how(xml parameter syntax, steps e.t.c)
I can do to allow users to specify the accountDetails parameter, its quite tricky for me coz its an xml type parameter, Im not sure if I should just specify the AccountNumber and
ReportType parameters separately:
I've tried the following without any success:
1. Under the dataset properties: I tried not to specify a default value for the accountDetails parameter on the xml query, then I added a parameter called "accountDetails" under the dataset parameters properties, then under parameter
value I added the following xml value :
<d4p1:AccountDetailDto>
<d4p1:AccountNumber>Parameters!AccountNumber.Value</d4p1:AccountNumber>
<d4p1:AccountType>Parameters!AccountType.Value</d4p1:AccountType>
</d4p1:AccountDetailDto>
(I also added the AccountNumber and AccountType parameters under the report data dialogue window)
This returns empty columns, is there something I'm missing, or am I doing this incorrectly?

Custom action with XML type input and output parameter.

Hi,
I want to develop custom action with xml type input and/or output parameter.
Is there sample code for java side. How is the definition of input and/or output parameter and set/get methods?
does it need special .jar file to develop custom action like this?
Thanks.

Cemil - yes, you can use XML data types. Use the class
com.sap.lhcommon.xml.XMLDataType
for your parameter type. Here is a snippet from a custom action we use to log XML (instead of just returning the #text node like the default logger does):
public class XMLLogger extends ActionReflectionBase
    private String source;
    private String eventType;
    private String textMessage;
    private XMLDataType xmlMessage;
    public XMLLogger()
        log = new Logger("UserLog");
        source = DEFAULT_SOURCE;
        eventType = TYPE_INFO;
        textMessage = "";
        xmlMessage = new XMLDataType();
    public XMLDataType getXmlMessage()
        return xmlMessage;
    public void setXmlMessage(XMLDataType xmlMessage)
        this.xmlMessage = xmlMessage;
    public void Invoke(Transaction transaction, ILog ilog)
        StringBuffer sb = new StringBuffer();
        sb.append('[');
        sb.append(source);
        sb.append("] ");
        sb.append(textMessage);
        sb.append(XMLUtils.convertXmlToString(xmlMessage));
XMLUtils is a helper class we wrote - it's just a bunch of standard Java XML boilerplate code. The important part you need to know is XMLDataType.getDocument() will return an org.w3c.dom.Document.
I hope that was enough information to help.

I’ll get an ora-19007.
Can some one point me in the right direction how to solve this error.
Thanks Roelof.

Who did you create the second table, in other words, how did you COPY the table as you said...
If you created the second table via a CTAS (create table as select) then you will have created a table that is not the same as the original one. AFAIK I have once created an enhancement request for this after discovering that JDeveloper, for example, creates a "copy" via a CTAS which creates the wrong structure. Double check via package DBMS_METADATA.

Help needed in inserting into column of XML type

i have requirement of inserting data into column of xml type
eg
cust product cost
1 a 3
1 b 7
1 c 5
now required result should
<PROD-LIST>
<a>3</a>
<b>7</b>
<c>5</c>
</PROD-LIST>
Please let me know how to achieve this , i was trying write function , it was working for one values ,but how to do if many values exist .

Take a deep breath, then retype this putting in all the words and punctuation you missed out the first time until it makes sense.
Your sample data, for example, could be better formatted using the [pre] and [/pre] tags to preserve formatting and put in a table format. Similarly with your output. Why are two of the numbers floating around freely in your xml but the 3rd isn't?

Binding ADF UI to a complex XML Type – Development Productivity, State Mgmt

Binding ADF UI to a complex Web Service – Development Productivity, Managing State, Etc.
For those scenarios when ADF UI has to be bound to a complex XML type, it seems that the direction taken by the ADF development team was to generate data-controls that map to complex XML types.
The major problem with this approach is the fact that application server does not manage state. For example, If application has to submit a purchase order to a web service then application server has to manage the shopping card state until its ready to be submitted.
In some previous forum threads it had been suggested that using generated data-controls is a “quick and dirty” solution for accessing web services and that a proper solution is to use generated Java Proxy Interface.
That implies many manually constructed entity objects, associations and overridden doDML methods, which is far less productive compared to entity objects generated from a database schema.
Suggestion and a Question for the ADF development team
From the logical model standpoint, there is no difference in between the XML schema and DB schema. Therefore, it is possible to generate entity objects and associations for XML Types of XML schema the same way it’s done for tables of Database schema. The only difference is serialization of CRUD operations on entity objects.
One way to handle this is:
-     Generate Application Module for a complex XML type. This application module should have methods for marshaling to/from corresponding XML type.
-     Generate entity object for each subtype within the complex XML type. In case of nested subtypes, generate association to a parent type.
-     Generate data control with actions that are bound to web service operations and code that serializes request message from corresponding AM and de-serializes response message to corresponding AM.
This way, ADF would offer the same productivity for the SOA development as one its currently offering for the ORM development.
Until the time when something like this is available, what would be the best approach for binding ADF UI to web services?
Feedback is greatly appreciated.

We have similar issues as our big portion of the UI is based on WS. We found that there is no easy way to map entity object structure to complex XML type (one EO can based on one flat type or domain can't be bound to UI directly). Oracle PMs, is there any better solution or future plans to address this issue?

Parsing the data from and xml type field

Hi - I have registered a schema and inserted arecord into the table with the xml type column. Now I want to parse the data from the xmltype field into a relational table. I have been using the following select statement to accomplish this - and it does work if there is data in all the selected fields but when the filed is null then the whole select statement fails and brings back 'no rows returned'.If the value is null I want the select statment to return null. please give any ideas.
SELECT version,frmd_transaction_date,extractValue(value(b), 'event_update/location')"location",
extractValue(value(b), 'event_update/sending_system')"sending_system",
extractValue(value(b), 'event_update/event_identifier')"event_identifier",
extractValue(value(b), 'event_update/event_link')"event_link",
extractValue(value(b), 'event_update/organization_code')"organization_code",
nvl(extractValue(value(c), '/schedule/event_duration_minutes'),'000')"event_minutes"
FROM fraamed_user.frmd_event_update , TABLE(xmlsequence(extract(xml_event_update, '/event_update')))b,
TABLE(xmlsequence(extract(xml_event_update, '/event_update/schedule')))c

...then I guess you have to rewrite the query.
Is schedule another xml sequence inside of event_update sequence ?
If it is not you can try this :
SELECT version,frmd_transaction_date,extractValue(value(b), '/event_update/location/text()')"location",
extractValue(value(b), '/event_update/sending_system/text()')"sending_system",
extractValue(value(b), '/event_update/event_identifier/text()')"event_identifier",
extractValue(value(b), '/event_update/event_link/text()')"event_link",
extractValue(value(b), '/event_update/organization_code/text()')"organization_code",
extractValue(value(b), '/event_update/schedule/event_duration_minutes/text()')"event_minutes"
FROM fraamed_user.frmd_event_update , TABLE(xmlsequence(extract(xml_event_update, '/event_update')))b
...if yes, did you try nvl function (I don't think this would be a solution of a problem):
SELECT version,frmd_transaction_date,nvl(extractValue(value(b), '/event_update/location/text()')"location", 'NULL VALUE'),
nvl(extractValue(value(b), '/event_update/sending_system/text()')"sending_system",'NULL VALUE'),
nvl(extractValue(value(b), '/event_update/event_identifier/text()')"event_identifier",'NULL VALUE'),
nvl(extractValue(value(b), '/event_update/event_link/text()')"event_link",'NULL VALUE'),
nvl(extractValue(value(b), '/event_update/organization_code/text()')"organization_code",'NULL VALUE'),
nvl(extractValue(value(c), '/schedule/event_duration_minutes/text()')"event_minutes",'NULL VALUE')
FROM fraamed_user.frmd_event_update , TABLE(xmlsequence(extract(xml_event_update, '/event_update')))b,
TABLE(xmlsequence(extract(xml_event_update, '/event_update/schedule')))c
If none of this works post your xml schema.

XML-Type and reference to unavailable DTD causes validation problems

Hi,
I'm fairly new to Oracle's XML features. I've created a view that produces XML from a number of tables. The resulting XML is used to be stored on a web site for download by customers (this is a manual process about once a week via a CMS). It contains a reference to a DTD that is available on the web server, too. This XML must also be stored in the Oracle database. The problem is that the Oracle Server is not allowed to access any web site (Oracle server is in inhouse network with no access allowed to the world outside). So I can't store the XML in an XML-type column, as the Oracle server wants to validate the XML against the referenced DTD. There is an option not to validate the XML. But then I get the error when I try to access the XML afterwards. So up to now I use a CLOB column to store the XML, but then I lose all the benefits of an XML-type column. Is there any workaround?
TIA,
Stefan

Newbie question on indexing XML type

I cannot get a query to use an index I created for an XML type. Here is my setup:
create table XmlTest( id number,
data_xml XMLType)
XmlType data_xml STORE AS CLOB;
I inserted 10,000 records like this ( each record has a unique id):
insert into XmlTest(id, data_xml) values
( 1
, XMLType('<company>
<department>
<id>10</id>
<name>Accounting</name>
</department>
</company>'));
I then created this index:
CREATE INDEX xmltest1
ON xmltest (extractValue(data_xml, '/company/department/id'));
When I run this query, it takes a long time - 12 seconds.
SELECT id from xmltest
WHERE EXISTSNODE( data_xml, '/company/department[id="37500"]') = 1;
it is doing a full table scan. What is wrong with my index?
Thanks!

I've yet to have the opportunity to work with indexes on XML data but I suspect it is because your index alone cannot satisfy the results of the query and the data you want is from every row in the table so a FTS is the best approach.
To restate, you are asking for the id value from the table where the XML contains a certain node. This node exists in every entry in the index, so why use the index if you have to go get data from the table.
Or it is because EXISTSNODE is checking for a different condition then your index was defined on. I suspect if you do something like /company/department/id[. = '10'] in your EXISTSNODE, it should use the index.
All this is a guess and the best place for you to look is the {forum:id=34} forum and also [Marco's Blog|http://www.liberidu.com/blog/]

Retrieving xpath in any xml type service

Hi,
We have any xml service type proxy which receives 2 different types of XML messages.In one of the XML messages,we need to branch out based on value of certain element.
But xpath doesn't seem to work.Xpath retrieved using messaging type service is:
*$body/ref:ONIXMessage/ref:Product/ref:RecordSourceType/text()*
This xpath works with messaging type service.
But when the same was used in any xml type service ,ALSB unable to recognize the namespace and hence the xpath was modified to:
*$body/ONIXMessage/Product/RecordSourceType/text()*
But this does not return anything.
Any idea as to how to get the data from xpath?
Thanks.
Arti

Hi,
You can add the namespace to use that in inline x-queries/x-path expressions. Please refer -

Versioning document in XML type coloumn

Hi All,
I have a specific requirement in my product.I have to version the data entered in XML type coloumn. I tried searching in google and oracle 9i doc but I got the information for versioning the document stored under a partcular directory using resource_view not for my set of requiremets.
Here I am giving more info:
created a table abcd(int id , xmlcol XMLType)
and associated a schema for this coloumn.Inserted data in xml format in the coloumn. I need to create different version of this data in xml type coloumn with new id.
If any of you worked on this / have some idea abt how to proceed will be very helpful to me...
Thanks in advance,
Cheers
Somasekar.

Hi
I am looking for some information for versioning the XMLType Column defined in the schema. The data inserted into the XML Type column will adhere to same schema.
Can anyone help me or point me to some information.
Thanks

PLSQL and Java XML type mapping

Running database 10gR2. Trying to create a Java stored procedure that returns an XML type (oracle.xdb.XMLType) like so:
class MyCoolClass
   static oracle.xdb.XMLType doSomething( String xmldata)
     oracle.xdb.XMLType xmlt = new oracle.xdb.XMLType( xmldata );
     return xmlt;
This, of course, is wrapped by a PL/SQL function:
function doSomething( xmldata varchar2 ) return SYS.XMLTYPE AS LANGUAGE JAVA
name 'MyCoolClass.doSomething(java.lang.String) return oracle.xdb.XMLType';
While everything compiles (that means it should work, right?), the above codes generates a runtime error ORA-00932 'inconsistent datatypes' error.   I'm not sure what I'm doing wrong, it was my understanding that a default mapping existed between the PL/SQL SYS.XMLTYPE and oracle.xdb.XMLType. Is what I'm attempting even possible?

Sorry, I was being sloppy with my code example. It should be:
class MyCoolClass
   static oracle.xdb.XMLType doSomething( String xmldata)
      java.sql.Connection c = java.sql.DriverManager.getConnection("jdbc:default:connection:");
     oracle.xdb.XMLType xmlt = new oracle.xdb.XMLType( c, xmldata );
     return xmlt;

Advantages Of XML Type Views

Hi Every one,
I am pretty new to XML Type views, and just want to ask few questions to every one. May be they do or don't belong here.. but help me out...
1. What are the advantages of XML Type Views?
2. Why should I prefer to use XML Type Views? (Is it only for querying the relational or XML data and result in XML format?)
3. I have a scenario, here I would like to develop a web service which would ultimately call a stored procedure to get relational data. Something like a DAL(Data Access Layer). In this scenario, what are the advantages that I am able to benefit if I use XML Type view with out using the regular stored procedures, which would give relational data(Not in XML format).

1) To define views that output relational data or object relational data in a XML format
2) You give the database more info regarding abouts its XML output / design via XML Schema and or inview defined integers so Oracle is capable to optimize the generation of its XML output
3) Don't over do it. The functionality called Native Database Web Services (NDWS) is already providing this for you natively in Oracle 11g and onwards.

Two classes have the same XML type name??? Please, help...

Hello!
I have a simple web service class. I generated the ws server-side classes using wsgen.
I created a jar file from the generated code.
Then :
Endpoint endPoint = Endpoint.create(
new WebServicesUnitImpl()
String wsFinalName = "http://localhost:9999/akarmi";
endPoint.publish( wsFinalName );
The web service started fine.
Then called wsimport, and the generated classes have been placed into a jar file.
Then called the code like this:
WebServicesUnitImplService service = new WebServicesUnitImplService();
WebServicesUnitImpl unit = service.getWebServicesUnitImplPort();
unit.serviceXXX();
but the code doesn't work at all, resulting this error message:
Two classes have the same XML type name "{http://ws.components.core.ilogique.vii.com/}getMessages". Use @XmlType.name and @XmlType.namespace to assign different names to them.
     this problem is related to the following location:
          at com.vii.ilogique.core.components.ws.GetMessages
          at public com.vii.ilogique.core.components.ws.GetMessages com.vii.ilogique.core.components.ws.ObjectFactory.createGetMessages()
          at com.vii.ilogique.core.components.ws.ObjectFactory
     this problem is related to the following location:
          at com.vii.ilogique.core.components.ws.GetMessages
I have this error report on all generated class file! How can i fix this?
What is the main problem? The SE usage? I copied the lates jax-ws jars into endorsed lib resulting the same.
Any help is appreciate.
