Register XML schema using dbms_xmlschema in Oracle 11g

I have a xsd file located at C:\temp\test.xsd
I need to register this schema to create a XMLType table for Object Relational XML Storage.
How do I register the schema for relational storage?
I do not seem to find any example on internet for registering the schema for relational storage.
Any help would be highly appreciated.

Thanks for help. The table is created now. But it created a CLOB table whereas I want a relational table with rows and columns. Is it because the schema was registered with SCHEMADOC as bfilename? How do I get the relational storage?

Hi! I faced the same problem as author of a thread. At first it was just the same and I used solution that was offered - add attribute xdb:SQLInline="false".
But now this error (ORA-01792: maximum number of columns in a table or view is 1000) became to rise on element that doesn't have a lot of attributes or subelements that coul exceed limit of 1000! Moreover it is based on complex type that already exists! It was created during another schema registration, which is included in schema that I'm trying to register now!
Does anyone challenged this problem?
I use Oracle9i Enterprise Edition Release 9.2.0.5.0

SQL*Loader problem - not efficient, parsing error for big xml files

Hi Experts,
First of all, I would like to store xml files in object relation way. Therefore I created a schema and a table for it (see above).
I wants to propagate it (by using generated xml files), hence I created a control file for sql loader (see above).
I have two problems for it.
1, It takes a lot of time. It means I can upload a ~80MB file in 2 hours and a half.
2, At bigger files, I got the following error messages (OCI-31011: XML parsing failed OCI-19202: Error occurred in XML processing LPX-00243: element attribute value must be enclosed in quotes). It is quite interesting because my xml file is generated and I could generated and uploaded the first and second half of the file.
Can you help me to solve these problems?
Thanks,
Adam

Problem in including a defined schema

Hi :
I am trying to register a schema using dbms_xmlschema.registerSchema().
I have registered one schema already and now I am trying to register another schema which has an "include" statement to refer the already registered schema. I do this by having the line below in the schema which I am trying to register :
<xs:include schemaLocation="feature.xsd"/>
I get an error as follows :
ERROR at line 1:
ORA-31000: Resource 'feature.xsd' is not an XDB schema document
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 0
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 26
ORA-06512: at line 2
Please let me know if this is valid. I queried the xdb.RESOURCE_VIEW and did find the feature.xsd registered as follows :
/sys/schemas/SPTREMBL/accelrys.com/feature.xsd
Thanks for your help.

I think I found the problem. Thanks

Schema won't register - same URL as non-existent schema

Hi,
Schema registration using DBMS_XMLSCHEMA.registerSchema(...) fails with 'An attempt was made to register a schema with the same URL as a previously registered schema'. However, when I try and delete using DBMS_XMLSCHEMA.deleteSchema(...) I get 'ORA-31000 Resource http://www.sepa.org.uk/RBMP/RBMP_datasheet.xsd is not an XDB schema document'. I also can't see the document in the ALL_XML_SCHEMAS view.
Only reference to a solution for this problem that I can find refers to using DBMS_XMLSCHEMA.PURGESCHEMA but I'm on 10g and this appears to be new in 11g.
Any ideas how I can get out of this one?

Thanks Marco, I'll try and get our DBA to purge the recycle bin and try again. Though I can't see anything there that looks like it relates to my schema.
The database version is 10.2.0.1.0. and I did the delete like this
     DBMS_XMLSCHEMA.deleteSchema(
     SCHEMAURL => 'http://www.sepa.org.uk/RBMP/RBMP_datasheet.xsd',
     DELETE_OPTION => dbms_xmlschema.DELETE_CASCADE_FORCE
It seemed to work as the underlying objects were dropped and the url isn't visible in ALL_XML_SCHEMAS. AFAIK I'm the only one currently working with XMLDB on this instance and I'm almost certain that I only had the one session open at the time.

Maximum length for an XML schema

Hi everybody,
Is there a limit on the maximum length for an XML schema? I am trying to register an XML schema using dbms_xmlschema.registerSchema(). The schema registration process seems to go fine when the length of the schema is short. But the registration process always hangs when I increase the XML schema with additional types/elements. Is there a limit on the maximum length of the XML schema with regards to registering it to Oracle?
Thanks!
IK

Hi Erhan,
Let's say I have a really big XML schema in file "schemaA.xsd", like so:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleA="http://abc.com/schemaA" targetNamespace="http://abc.com/schemaA">
<xsd:element name="Employee">
<xsd:sequence>
<xsd:element name="Address" type="sampleA:AddressType"/>
<xsd:element name="Contact" type="sampleA:ContactInfoType"/>
</xsd:element>
<xsd:complexType name="AddressType">......</xsd:complexType>
<xsd:complexType name="ContactInfoType">....</xsd:complexType>
</xsd:schema>
I can separate this schema into multiple smaller schemas (<32KB) by using the proper imports:
In file "sampleA.xsd":
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleB="http://abc.com/schemaB"
xmlns:sampleA="http://abc.com/schemaA" targetNamespace="http://abc.com/schemaA">
<xsd:import namespace="http://abc.com/schemaB" schemaLocation="schemaB.xsd"/>
<xsd:element name="Employee">
<xsd:sequence>
<xsd:element name="Address" type="sampleB:AddressType"/>
<xsd:element name="Contact" type="sampleB:ContactInfoType"/>
</xsd:element>
</xsd:schema>
And in file "sampleB.xsd", I might have something like this:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sampleB="http://abc.com/schemaB" targetNamespace="http://abc.com/schemaB">
<xsd:complexType name="AddressType">......</xsd:complexType>
<xsd:complexType name="ContactInfoType">....</xsd:complexType>
</xsd:schema>
So, you see how I have separated that one really big XML schema in file "schemaA.xsd" into two XML schema files: "schemaA.xsd" and "schemaB.xsd". Also, I have added <import> tags in schemaA.xsd to refer to elements, complext types, etc. defined in schemaB.xsd. So long as these schema files are < 32KB, I can register them (using dbms_xmlschema.registerSchema()) without any problems into Oracle.
Let me know if what I said above is not too clear. Hope you find your solution soon!
Thanks!

Validating against an XSD

I'm trying to validate an imported XML file (in a clob) against an XSD. It is slightly complicated in that the XSD import another. I have tried to register both, using dbms_xmlschema.registerSchema, but the second one gets:
ORA-01031: insufficient privileges
ORA-06512: at "XDB.DBMS_XDBZ0", line 275
ORA-06512: at "XDB.DBMS_XDBZ", line 7

ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 61
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 126
ORA-06512: at line 25
I've not found much information on this topic. Any ideas?
I have a supplemental question. This file is being parsed using XMLDOM. Is there a way to extract an element and its contents as a piece of XML text that I can include in an error log?
Thanks
Steve

Now I remember why we switched to using XMLTYPE when extracting information from the XML in PL/SQL.
declare
l_main_doc    dbms_xmldom.DOMDocument;
l_main_xml    XMLTYPE;
l_output      VARCHAR2(500);
l_clob        CLOB := 'a';
l_sample      VARCHAR2(500);
l_nodelist dbms_xmldom.domnodelist;
begin
l_sample := '<Block>
<Item><Record>1</Record><Value>123</Value></Item>
<Item><Record>2</Record><Value>999</Value></Item>
</Block>';
-- DOMDoc way
l_main_doc := dbms_xmldom.newDOMDocument(l_sample);
l_nodelist := dbms_xslprocessor.selectnodes(dbms_xmldom.makenode(l_main_doc),
                                              '/Block/Item[Record="2"]');
dbms_xmldom.writeToClob(dbms_xmldom.item(l_nodelist,0),l_clob);
dbms_output.put_line('#1');
dbms_output.put_line(l_clob);
dbms_xmldom.freeDocument(l_main_doc);
-- XMLType way
l_main_xml := XMLTYPE(l_sample);
l_output := l_main_xml.extract('/Block/Item[Record="2"]').getStringVal();
dbms_output.put_line('#2');
dbms_output.put_line(l_output);
end;outputs
#1
<Item>
<Record>2</Record>
<Value>999</Value>
</Item>
#2
<Item>
<Record>2</Record>
<Value>999</Value>

3) I use INSTEAD OF trigger for Object View to insert the data to database.
I got the message is:

Anybody can give me the advise for that.

If you have the ftp server at 8080 running (9iR2 only) the simples way is to upload it to the database through that server. You can then do whatever you want using the xdburitype() procedure.
Below is an excerpt of a script I use to register XML schema's (I've got some very long ones, about 150K). It should work with "any" file..
begin
     dbms_xmlschema.registerSchema (
          schemaURL => 'http://www.agralin.nl/WebQuery/ns/&1',
          schemaDoc => xdburitype('/age/&1..xsd'),
          local => TRUE,
          genTables => FALSE,
          genbean => FALSE,
          genTypes => TRUE,
          force => FALSE,
          owner => 'AGE'
end;

Error while trying to use BFILENAME during schema registration

Hi,
I'm having difficulty in understanding the BFILENAME function while trying to register a schema. The schema is physically present in the following location
USERNAME: WEBUSER
LOCATION: XML Schemas ---> MyHeaderSchema.xsd
And I'm trying to register it as follows:
declare
V_XML_SCHEMA XMLTYPE := XMLType(BFILENAME('WEBUSER','MyHeaderSchema.xsd'),nls_charset_id('AL32UTF8'));
begin
DBMS_XMLSCHEMA.registerSchema
SCHEMAURL => 'http://my.schemas.com/header.xsd',
SCHEMADOC => V_XML_SCHEMA,
LOCAL => TRUE,
GENBEAN => FALSE,
GENTYPES => TRUE,
GENTABLES => FALSE,
ENABLEHIERARCHY => DBMS_XMLSCHEMA.ENABLE_HIERARCHY_NONE
end;
I get the error:
Error report:
ORA-22285: non-existent directory or file for FILEOPEN operation
ORA-06512: at "SYS.XMLTYPE", line 296
ORA-06512: at line 2
22285. 00000 - "non-existent directory or file for %s operation"
*Cause: Attempted to access a directory that does not exist, or attempted
to access a file in a directory that does not exist.
*Action: Ensure that a system object corresponding to the specified
directory exists in the database dictionary, or
make sure the name is correct.
Can you please help?

I was curious if there was already some functionality in SQL Developer I might have missed. So I checked. Apparently SQL Developer still doesn't have any functionality to support XML Schema's in / for XMLDB (I keep them asking, but anyway).
So an XML Schema is just treated as plain text. Still.
However, the following worked for me. Is there a difference if I use XDBURIType Vs BFILENAME and do a getBLOB() Vs XMLType?XDBUriType is part of the URIType factory functionality and in this case, XDBUritype enables you to get the content stored out of the XDB Repository
BFileName give you the possibility to get your content from the server via a BFile locator construct
getBLOB is an operator on xdburitype and converts the uritype datatype into binary LOB datatype
XMLType is the datatype that should be used for XML content
If you use GENTYPES => TRUE then during registration via using DBMS_XMLSCHEMA objects and types will be created to "represent" the "format" of the XML defined by the XML Schema.

Performance issues - which oracle xml technology to use?

Our company has spent some time researching different oracle xml technologies to obtain the fastest performence but also have the flexibily of a changing xml schemas across revs.
Not registering schemas gives the flexibity of quickly changing schemas between revs and simpler table structure, but hurts performance quite a bit compared to registering schemas.
Flat non xml tables seems the fastest but seeing that everything is going xml, this doesn;t seems like a choice.
Anyhow, let me know any input/experience anyone can offer.
here's what we have tested all with simple
10000 record tests, each of the form:
insert into po_tab values (1,
xmltype('<PurchaseOrder xmlns="http://www.oracle.com/PO.xsd"

Errors when using inplace schema evolution

Hi, i have been having some issues when attempting to use inplace schema evolution to add a new element into an existing xsd file currently registered on the database and was looking for some help with this if possible.
Firstly, Oracle details are as follows :
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
PL/SQL Release 11.2.0.2.0 - Production
"CORE     11.2.0.2.0     Production"
TNS for IBM/AIX RISC System/6000: Version 11.2.0.2.0 - Production
NLSRTL Version 11.2.0.2.0 - ProductionThe xsd registered on the database is called truncheadtest2.xsd :
<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" xdb:storeVarrayAsTable="true">

     </xs:element>
     <xs:element name="clientRiskEventHeader" xdb:defaultTable="EVLN_CLIENTRISKEVENTHEADER">
          <xs:complexType xdb:SQLType="EVLN_CLIENTRISKEVENTHEADER_T">
               <xs:sequence>
                    <xs:element ref="title" xdb:SQLName="TITLE"/>
               </xs:sequence>
          </xs:complexType>
     </xs:element>
</xs:schema>registered via :
BEGIN
DBMS_XMLSCHEMA.registerSchema(
   SCHEMAURL => 'http://xmlns.kfis.co.uk/testevheader/xsdin/truncheadertest.xsd',
SCHEMADOC => XDBURIType('/public/web_quotes/header/xsd/test/SchemaTest/truncheadtest2.xsd').getCLOB());
END;i have then created a new xsd, to add the new element to the xsd (using minoccurs to allow backwards compatibility between xml files conforming to the 1st xsd and this new xsd), called truncheadtestfn3.xsd :
<?xml version="1.0" encoding="UTF-8"?>

               </xs:sequence>
          </xs:complexType>
     </xs:element>
</xs:schema>I can run the following code to create the difference doc between the 2 versions of the schema document, without errors:
DECLARE
   schemaDiff XMLType;
   res boolean;
BEGIN
   SELECT xmlDiff
        xdburitype('/public/web_quotes/header/xsd/test/SchemaTest/truncheadtest2.xsd').getXML(),
        xdburitype('/public/web_quotes/header/xsd/test/SchemaTest/truncheadtestfn3.xsd').getXML()
   INTO schemaDiff
   FROM dual;
   IF (dbms_xdb.existsResource('/public/web_quotes/header/xsd/test/SchemaTest/header.xml')) THEN
       dbms_xdb.deleteResource('/public/web_quotes/header/xsd/test/SchemaTest/header.xml');
   END IF;
   res :=
     dbms_xdb.createResource('/public/web_quotes/header/xsd/test/SchemaTest/header.xml',schemaDiff);
     dbms_xmlschema.inPlaceEvolve('http://xmlns.kfis.co.uk/testevheader/xsdin/truncheadertest.xsd',schemaDiff,2);
END;
/ which creates the following xml file:

</xd:xdiff>However, when i then run the inplace schema evolution code for option 1, i get the following error:

Thanks.

Hi,
When you use INPLACE_TRACE flag, it traces the operations that would be performed with option 1.
If you look at the trace file produced in this case, you'll see where the error is coming from :
------------ QMTS Executing SQL ------------
ALTER TYPE "TEST"."EVLN_CLIENTRISKEVENTHEADER_T" ADD ATTRIBUTE "FORENAME" VARCHAR2 CASCADE NOT INCLUDING TABLE DATA
/The mandatory length specification is absent.
I thought adding an explicit xs:maxLength restriction would solve the problem, but it happens the generated DDL still lacks the length specification.
After some tries, I found that the issue seems related to the usage of ref elements in the schema.
On a side note, it's not the first time we see problems associated with ref (Cf. how do i get xml db to work right with imported or included schemas?).
The workaround is to use a named type.
I've also added an xdb:defaultTable annotation to the top-level element ("title") so that the registration process doesn't generate a table for it :
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb" xdb:storeVarrayAsTable="true">
