Multiple XML schema in structured XMLType column possible?

I have registered several different xml schema in my 10g database. I have a table with an XMLType column. That column will always hold one XML document that conforms to one of the XML schema. Question: does that by definition mean I have to use "unstructured" storage, or there any way to use structured storage telling Oracle that the XMLType conforms to xsd1 OR xsd2 OR xsd3?
Thanks.

In 10gR2 a column based on an XML Schema and using object-relation storage can be bound to one global element. The only way for a column to hold documents associated with more than one global element is if both elements are defined as members of the same substition group.

LPX-00004 - Problems while inserting xml files in a xmltype column

I've faced two problems while trying to insert xml files into my table containing a xmltype column:
create table xml_test (id number(20),content xmltype)
I use following java code for writing xml docs into db:
     conn.setAutoCommit(false);
     OraclePreparedStatement stmt = (OraclePreparedStatement)
          conn.prepareStatement("INSERT INTO xml_test (id,content) VALUES(?,?)");
     File file = new File(file1);
     InputStream in1 = new FileInputStream(file1);
     Reader r1 = new BufferedReader(new InputStreamReader(in1, "UTF-8"));
     int len = 0;
     StringBuffer text = new StringBuffer();
     while ((len = r1.read()) != -1) {
          text.append((char) len);
     in1.close();
     r1.close();
     XMLType poXML1 = XMLType.createXML(conn, text.toString());
     for (int i = 1; i <= 1; i++) {
          stmt.setInt(1, i);
          stmt.setObject(2, poXML1);
          stmt.execute();
     conn.commit();
1. problem: occures only if a xml schema has been assoicated to the specific xmltype column. it seems that the length of a specific xml tag in the document is limited. but why?

It's hard for me to tell you more without seeing your instance data, but for problem #1, if you look at the underlying SQL types being generated by your schema, you will see that the default SQL mapping for a "string" in your schema is a VARCHAR2(4000) (and I believe this would be only 2000 for a varying width character set like UTF8).
You can specify that you wish this column to be mapped as a CLOB in your schema if this is the problem. Also note that there is a 64K limit on the size of an individual node in XMLType.

Permission issues accross schemas to load XMLTYPE column - structured storage

Hi,
We have a table in BIUSER schema this table is object-realtionally stored with XMLs. When we are trying to load receords from ETLUSER schema we are getting the error as
Record 1: Rejected - Error on table "BIUSER"."PWAYWORKFILE_TABLE".
ORA-00604: error occurred at recursive SQL level 1
ORA-01031: insufficient privileges
Heres the oracle installation details
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
"CORE 11.2.0.3.0 Production"
All the records are moving to the bad file, whereas the same load happens normally in its own schema i.e. BIUSER
Suspecting this as permission issues we have already given the permission to the table sysnonym as given below in the registration script.
We googled and found few things about ACLs that we are not sure of , its that is the issue please let us know if this table can be created and loaded from different schema
Heres the table creation and registration script

Hi MarcoGralike,
I have finally acquired a sample schema and xmls to reproduce the errors that i am getting even after acquiring XDBADMIN privilege and registering my schema as GLOBAL.
Here's the problem i am facing, whenever i intend to store the PublisherList (publisher.xsd) out of line while registration i am running into insufficient privilege issues even if i have the schema registered using (LOCAL => FALSE), whereas it runs smooth in BIUSER and if i dont set it out of line it works in ETLUSER as well.
Here are the 2 XSD files
books.xsd   --- this is the root element
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" version="1.0" xdb:storeVarrayAsTable="true">
<xs:include schemaLocation="publisher.xsd"/>
<xs:element name="books" type="bookType"/>
<xs:complexType name="bookType" abstract="true">
    <xs:sequence>
    <xs:element name="author" type="xs:string" minOccurs="0"/>
    <xs:element name="title" type="xs:string" minOccurs="0"/>
    <xs:element name="genre" type="xs:string" minOccurs="0"/>
    <xs:element ref="PublisherList" minOccurs="0"/>
   </xs:sequence>
   </xs:complexType>
</xs:schema>
publisher.xsd -- this is a child elelment which in my actual scenario is so big that i must keep it out of line during registration
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" version="1.0" xdb:storeVarrayAsTable="true">
<xs:element name="PublisherList" type="PublisherListType"/>
<xs:complexType name="PublisherListType">
    <xs:sequence>
    <xs:element name="Name" type="xs:string" minOccurs="0"/>
    <xs:element name="Office" type="xs:string" minOccurs="0"/>
   </xs:sequence>
   </xs:complexType>
</xs:schema>
Here's the sample XML
<?xml version="1.0"?>
<books xmlns:xs="http://www.w3.org/2001/XMLSchema">
      <author>Writer</author>
      <title>The First Book</title>

How to import multiple XML schemas in Toplink.

Hi All,
I try to import multiple Schema(defined by EPCGlobal) in toplink This schema imports few other schemas and all are available in the same location.
For this I tried to create a project by selecting XML radio button, and specified an XSD. The classes are getting generated for this file. After this, I try to import all other schema's using the Import schema option. I'm able to import it. but, I'm not able to generate classes for the schemas imported recently. Can you please let me know whether this is the expected behaviour..?
Alternatively, I try to import a Schema(defined by EPCGlobal) in toplink through a TopLink-Jaxb Project. But I get the following exception..
oracle.xml.parser.schema.XSDException

As I'm struck with this problem, please throw some light in this regard.
Thanks
Rajasekaran

Rajasekaran,
I have examined your XML schemas and do not believe that the problem is due to the import. Instead it is because the XML schema being imported is itself invalid. I have emailed you the specific correction to your XML schema. It was an error related to the namespace qualification of the type in one of your element declarations.

How to store XML fragments in a XMLTYPE column

Hi all,
maybe just another newbie question.
I've imported a lot of xml documents into an Oracle table with a xmltype column (stored as CLOB). Now I try to select a specific part of these documents and store thsi xml fragment in another table, also in a xmltype column.
Unfortunately this doesn't work, I get ORA-19010: Cannot insert XML fragments.
What can I do to store part of a xml document?
Best regards
Matthias

Is there a way to transform the xml fragments into valid xml documents?

ORA-00911:invalid character when loading an XML doc to the XMLType column

We have followed this code snippet: http://www.oracle.com/technology/sample_code/tech/java/codesnippet/xmldb/Example_Code.html#createclob
using the CLOB object to load an XML Document which has more 4000 characters to the XMLType column, we got the error -- ORA-00911:invalid character.
Sound likes an encoding issue? any suggestions would be appreciated.
BTW, we're able to use the TopLink's mapping -- Direct-to-Field to insert an XML String (<4000 characters) to the XMLType column.
Thanks!

Try removing the semi-colon at the end of your statement. That is the cause of ORA-911 with DBMS_SQL.PARSE and EXECUTE IMMEDIATE, I don't see why ADO should be any different.
Cheers, APC

Disable Schema validation in XMLTYPE Column

Hi all!
I have created the following table with an Schema-based XMLTYPE column:
CREATE TABLE ADR1 (
idnr NUMBER,
FileType XMLTYPE,
constraint pk_idnr primary key (idnr))
XMLTYPE COLUMN FileType STORE AS CLOB
XMLSCHEMA "http://localhost:8080/home/usr/xsd/cc.xsd"
ELEMENT "File";
Now i want to disable the schema - validation for the XMLTYPE Column. I have done this before for an XMLTYPE Table. But in this case of an XMLTYPE Column i cant find the Constraint, that belongs to the Column.
Thanks for your help!
Axel

Weird explain plan on multi-level structured XmlType column

Hello,
am running an explain on the follwing query on 11.2.0.2:
SELECT
T1.EVENT_ID,
ACTION_SUB_ID,
PARAM_KEY,
PARAM_VALUE,
TO_DATE('2013-12-10', 'YYYY-MM-DD')

WHERE MESSAGE_ID = 4972102 ;
Although MESSAGE_ID is the primary key of T_C_RMP_MNTRNG_XML_FULL_IL and thus there is only one record matching the condition, I get an explain plan with huge costs, 500MB of data and an estimated 10 hour runtime:

When I run the query, the result comes back within 0.3 seconds.
Why is the explain plan off like that?
Is this just the way it is, or is there something going wrong here?

This is my table create statement:

) RETURN AS LOCATOR
XMLTYPE XML_CONTENT STORE AS OBJECT RELATIONAL XMLSCHEMA "http://mydomain.com/csc_monitoring_session.xsd" ELEMENT "monitoring";
I set all default table names in the schema to blank and registered the schema with genTables=false.
I am still running into problems retrieving the 3rd level T_OR_MON_ACTION_PARAM data. The query just crashes after a while because it is running out of either TEMP space or UNDO space (it keeps changing). I'll take a step back to re-evaluate and post another thread about that in a bit I guess...
You said "SQL*Plus explain plan, goes most of the time bananas" - is there a difference in what client (SqlPlus or SqlDeveloper) I use to get the explain plan? I thought the plan was generated by the DB and the clients just display the result, and the only difference is the way the clients display the plan?!

How to add Multiple XML Tags for a single column for an RDF

Hi Gurus,
I have Requirement in the Oracle D2k Report from which we are generating the xml tags.
My Requirement is in a table i have 2 columns say A and B.
i am able to generate three xml tags separately using the report builder by clicking on the column name and in the xml setting giving the xml tag.
eg: table Acount contains 2 columns A and B with respective data
A B
QT 1
QTS 0
QTR 2
i am able to general xml tags like this
<ACount>
<AStatus>QT</AStatus>
<HeadCount>1</HeadCount>
</ACount>
<ACount>
<AStatus>QTS</AStatus>
<HeadCount>0</HeadCount>
</ACount>
my requiremnt for the xml tags is
<ACount>
<AStatusQT>1</AStatusQT>
<AStatusQTS>0</AStatusQTS>
</ACount>
kindly help me out how to achieve this requirment in the rdf file mulitple xml tags.
all your input are most valuable to me, thanks in advance

I'm sorry for being so dense, but I'm not quite following, although what I've tried makes me think if I can follow you, it will work :)
To answer your initial questions, you are correct with both your assumptions:
1) detailType is the parameter that specificies YTD/Weekly, this is a "report defined" parameter that I am using to determine which Row Group to display (either YTD or Weekly)
2) SchoolDaysActiveWeek is the parameter that is being set to either true or false -- this is a field in the cube that states whether that record is for the current week or not
So in following your instructions, well that's the problem I'm not quite following :)
1) When you say Delete the SchoolDaysActiveWeek parameter from the report only, do you mean to mark the parameter as Hidden? If so, I've done this.
2) I'm not quite sure where to use the statement you provided me. You said to put it in the dataset, but I don't know which dataset. I assume you mean the "main" dataset (as opposed to the hidden dataset that gets generated when you mark a field
as a parameter). If this is the case, the only place I could see that would allow you to use such a statement is in the Filter section of the properties. I tried this, and it did not generate any errors, but it also kept my report groups from displaying
-- it just showed a blank report, so I think it probably wasn't bringing back any rows to populate them with.
I also tried going into the Expression section for the SchoolDaysActiveWeek parameter in the second screenshot and placing the statement there. When I did this and ran the report, I would get the following error:
The 'SchoolDaysActiveWeek' parameter is missing a value
So what am I missing!?
Also, thanks for taking the time to respond!!

How to handle multiple xmls(schemas) using java

Can anyone give me solution for the below issue.
We are handling five types of xmls(five different xsds) in our application.We have the XML and its XSD in database. Currently we are using JAXB to create and update the xmls.
In future there is a chance to add new schema. In that case our current code will not work (because the JAXB is tightly coupled with the xsds) for new schema. Is there any technology or method to handle this situvation?
I am looking for early respons.
Thanks
Dhans

You have no idea? Then look in your JavaMail download and you will find several sample programs that you can use to get started. It would also help to read the JavaMail FAQ (Google will find it easily for you).

Generate XPaths from an XMLType column?

Is it possible to load an XML schema into an XMLType column and then generate a list of all the XPaths in that schema?
If so how can this be done:?

kcuster,
Here is how you could load it. Maybe someone else has some ideas on generating the XPaths.

How to Generate and Register XML Schema

Does any one know how to gererate Oracle type XML schema provided XML file and register to XMLType field?
Thanks for any expert suggestion...

The SQL statement below shows how one can register XML schema to an XMLType column:
create table po_tab(
id number,
po sys.XMLType
xmltype column po
XMLSCHEMA "http://www.oracle.com/PO.xsd"
element "PurchaseOrder";
Similarly you can register XML schema to the INVDOC field in the your INVOICE table.
Hope it helps

XML Schema -- xsi:null in document instance and nullable in XSD

Hi,
I have an XML document
<DOC>
<EMP_ID>1</EMP_ID>
<EMP_NAME>Scott</EMP_NAME>
<EMP_ADDRESS>USA</EMP_ADDRESS>
</DOC>
As to what I understand, for the document to look like
<DOC>
<EMP_ID>1</EMP_ID>
<EMP_NAME>Scott</EMP_NAME>
<EMP_ADDRESS></EMP_ADDRESS>
</DOC>
with no value in <EMP_ADDRESS> tag, I have to use nullable attribute in XSD and xsi:null attribute in document. Is there any other way where we don't make any modificaitons in the document

Hi, Thanks for the reply.I have a scenario like this :
1. We have lot of xml files in our application server ( size ranges form 2 MB to 200 MB).
2. We have xml schema based structured storage for a column "personjoininfo" for a relational table --- Table is :
CREATE TABLE PERSON_COMP_TABLE
empId VARCHAR2(100) CONSTRAINT pk_PERSONCOMP PRIMARY KEY
,comments VARCHAR2(20)
,joindate DATE
,personjoininfo xmltype
XMLTYPE COLUMN personjoininfo XMLSCHEMA "www.PersonInfoUrl.com" element "person"
3. What is the best option for me to load the xml files in the personjoin info column along with the other column values.
As I know , if I use the XML DIR ( directory feature ), I would need to put these xml files in the database server for loading ---
So, what are my options in this scenario for loading these xml files ?
Thanks

CREATE INDEX "OCA_DEV"."OCA_STATUS_CODE_INDEX" ON "OCA_DEV"."DOCUMENT_STATUS_XML" (EXTRACTVALUE('/ocaStatus/status/statusCode'));
CREATE INDEX "OCA_DEV"."OCA_STATUS_DATE_INDEX" ON "OCA_DEV"."DOCUMENT_STATUS_XML" (EXTRACTVALUE('/ocaStatus/status/statusDate'));
However the problem is that I will be having multiple status within each XML which violates the Indexing.
Is there any way I can still create the Indexes allowing multiple status values in each XML?
Thanks in advance.

Hi,
You may want to store your document as a schema-based, object-relational XMLType to achieve that.
Then you'll be able to create indexes on the nested table used to store each "status" element.
Here's an example based on your sample document.
1) First, create and register a schema. The following is basic but sufficient here, let's call it "ocastatus.xsd" :
<?xml version="1.0"?>
<xsd:schema

Unable to load into XMLTYPE column

HI Gentlemen,
I have considerable difficulties with loading XML content into an XMLTYPE column. Here are the annotated schemas:

    <ehd:origination_dttm V="2009-11-10+01:00"/>Guilty is allegedly origination_dttm with its time zone. However, consider the type resolution below that leads to xs:date. This should be able to accommodate the time zone as well.

     <xs:complexType name="v_date_typ">
          <xs:attribute name="V" type="xs:date" use="required"/>
     </xs:complexType>When I delete the time zone portion in the instance document, it again works.
(However, other errors will then be reported--another issue.)
Can you help me to find out what is wrong? Is it my error or a bug?
Thanks, kind regards,

This is Oracle feature (at least in 11g R2). See Working with Timezones from XML DB Developer's Guide: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e16659/xdb05sto.htm#autoId62
The chapter also includes an example how to adjust the schema with Oracle specific annotation.
