How can I refer an xml Schema that was registred in Oracle xml DB
How can I refer an xml Schema that was registred in Oracle xml DB, from other xml schema?
I have the follow schema,:
<?xml version="1.0" encoding="AL32UTF8"?>
<xsd:schema targetNamespace="schemastipostasa.xsd"

</xsd:simpleType >
</xsd:schema>
I registred the schema written above with the folowwing pl*sql :
DECLARE
direc varchar2(2000);
nombreArch BFILE;
mens varchar2(2000);
BEGIN
direc:=uso_comun.pack_mail.fun_valor_param('TASA','DIR_DBSERVER');
nombreArch:=bfilename(direc,'schemas_tipos_tasa.xsd');
DBMS_XMLSCHEMA.registerSchema(
SCHEMAURL => 'http://xmlns.oracle.com/tasa/schemas.tipos.tasa.xsd',
SCHEMADOC => nombreArch,
LOCAL => TRUE,
CSID => nls_charset_id('AL32UTF8'));
dbms_lob.CLOSE(nombreArch);
dbms_output.put_line('salio sin cancelar');
exception
when others then
mens:=sqlerrm;
dbms_lob.CLOSE(nombreArch);
rollback;
raise_application_error (-20001,'en registro shcema='||mens);
END;
Then, I want to register the following schema, that mention de schema above:
<?xml version="1.0" encoding="AL32UTF8"?>
<xsd:schema targetNamespace="schema.repuesto.xsd"

<xsd:element name="INGRESO_POR_FALTANTE" type="tns:condicionType" />
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
But when a run the following script whith the same db-user:
DECLARE
direc varchar2(2000);
nombreArch BFILE;

BEGIN
direc:=uso_comun.pack_mail.fun_valor_param('TASA','DIR_DBSERVER');

nombreArch:=bfilename(direc,'Schema_repuesto_nuevo.xsd');
DBMS_XMLSCHEMA.registerSchema(

dbms_lob.CLOSE(nombreArch);
dbms_output.put_line('salio sin cancelar');
--commit;
exception
when others then
mens:=sqlerrm;
dbms_lob.CLOSE(nombreArch);
rollback;
raise_application_error (-20001,'en registro shcema='||mens);
END;
tell me the error: ORA: 01031, insufficient privileges!!!!, what’s wrong??,Hi,
To register schema, you require XDBADMIN system privilege granted to the user.
Please verify this and retry.

When I save file as "Word XML document", what kinds of schema does MS word using? Is it possible to use another XML schema? If so, how?
Plus, is it possible to use VBA inside MS word so that I can create save as "Word XML document" inside the "Save as type option"?Hi UW,
>> When I save file as "Word XML document", what kinds of schema does MS word using?
Word uses its own XML schema.
>> Is it possible to use another XML schema? If so, how?
Yes, you could use your custom XML schema. The link below shows more details:
# What You Can Do with Word XML [Word 2003 XML Reference] -- Microsoft Office Word 2003 XML Software Development Kit
https://msdn.microsoft.com/en-us/library/office/aa223584(v=office.11).aspx
For how to use another XML schema, you could refer the link below:
# Create a rich Word document based on your own custom XML (without the need for XSLT)
http://blogs.msdn.com/b/brian_jones/archive/2006/01/09/customxml1.aspx
>> is it possible to use VBA inside MS word so that I can create save as "Word XML document" inside the "Save as type option"?
What do you mean by "create save as "Word XML document" inside the "Save as type option"?"? Do you mean you want to create a new option in the Save as type option? In my option, you could not. The FileFormat in the Document
was specified by WdSaveFormat Enumeration. You could not modify the WdSaveFormat Enumeration. You could refer the link below:
# WdSaveFormat Enumeration (Word)
https://msdn.microsoft.com/en-us/library/office/ff839952.aspx
In addition, if you have any issue about using another XML schema, I will recommend you post a new thread.
The reason why I suggested is:
#1 There would be more community members to discuss the question.
#2 For people who have the similar question, it would be easier for them to find the answer from a specific thread.

Can't import XML schema with ref to external namespace
In TopLink 10.1.3 Dev Preview 3 (build 041116), I have 2 simple schema files. One defines an element as a ref to an element in the other schema, so the ref points to an element in an external namespace. TopLink won't import this schema.
First schema, imports fine:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.oracle.com/employee"
xmlns="http://www.oracle.com/employee"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="employee">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Second schema, fails import with "ERROR: null. Please check to ensure the document conforms to the XML Schema specification and try again":
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.oracle.com/department"
xmlns="http://www.oracle.com/department"
xmlns:employee="http://www.oracle.com/employee"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:import
namespace="http://www.oracle.com/employee"
schemaLocation="employee.xsd"/>
<xs:element name="department">
<xs:complexType>
<xs:sequence>
<xs:element ref="employee:employee" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Both schemas are valid according to the W3C schema validation checker at http://www.w3.org/2001/03/webdata/xsv.
I can work around the issue by putting the employee definitions into the department schema file so that all elements are in the same namespace. But I would like the schemas to be in separate files for better modularity and maintainability.
Am I doing something wrong? I would really like to be able to use references to external namespaces in my element definitions.
Thanks,
DaveHello David,
Apologies, but this is a bug in DP3 with respect to references to elements in imported namespaces. This has been fixed in current code, but until you get that, there are a couple ways to work around it:
==========================================================
1) Use an include rather than an import.
department.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
targetNamespace="http://www.oracle.com/department"
xmlns="http://www.oracle.com/department"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:include schemaLocation="employee.xsd"/>
<xs:element name="department">
<xs:complexType>
<xs:sequence>
<xs:element ref="employee" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>employee.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.oracle.com/department"
xmlns="http://www.oracle.com/department"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="employee">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>You should only have to import the parent schema (i.e. department.xsd), as the included document will automatically be built in. Note that this works for imports as well, provided that there aren't nasty bugs blocking the process.
==========================================================
2. Build everything into the same document
department.xsd
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema
targetNamespace="http://www.oracle.com/department"
xmlns="http://www.oracle.com/department"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="department">
<xs:complexType>
<xs:sequence>
<xs:element ref="employee" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="employee">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>Obviously, this one won't work quite as well in some cases.
==========================================================
Until you can get to the latest code, I hope this helps some.

Refer to another element in xml schema
Hello
i havea very basic question.
i am writing an xml schema. I'd like to ask that what should i do if i want to create an element which refers to another element within the same xml file.
Regards,

<xs:element name="A">
<xs:complexType>

XMLType column based on XML Schema: several questions
Hi,
I've a table on an oracle db version 10.1.0.4 where I stage the xml files containing orders created on a third party's system using BizTalk.
Although the storage I opted for is based on an XML Schema, defined by this third-party, I am facing big perfomance issues with files bigger than a few hundreds of kBs.
For instance, a 32Mb file takes more than 2 hours to be processed.
Now, after reading other threads in this forum and the documentation, my understanding of the problem is that the whole issue is with the correct indexing of the nested tables.
Here is my current XML Schema definition:

When I registered the XMLSchema, the following types and tables were automatically created and you can see the hierarchy below:
(by the way, I could not find any xdb_utilities.printNestedTables mentioned elsewhere)
XML_ORDERS

|___ProdRun382_T
|_____PickWave388_COLL
|_______PickWave383_T
|_________Customer387_COLL
|___________Customer384_T
|_____________InvOrder386_COLL
These objects are then used in the following nested tables:

Note that I cancelled this operation before it was over so I imagine that these figures refer to the statistics as of the time when the operation was interrupted.
So, here are finally my questions.
In order to create the constraints on the nested tables as shown in other threads, do I need to drop the existing xml_orders table and ancillary object types and recreate them or is there a way to add such constraints using the existing system generated object names?
Secondly, the xml_orders table may contain severale documents, not just one and his current primary key is the column ID. So, in order to uniquely identify the deepest element in the xml document, I need first to select the relevant document by means of the id column.
Would it be better to create the indexes containing this id column together with the nested_table_id and array_index?
Thanks for you help.

PS: I wrote a 10 lines xsl transformation that I passed on to Saxon together with the 32Mb file. It took less than 1 minute to produce a flat file that was loaded almost instantly by SQL*Loader. So, what I am looking for is a procedure loading this stuff in less than 2 minutes or possibly less.Does the following help

How to validate generated XML-Document in Memory by XML-Schema?
Hi all!
I have the following problem:
I am generating a Document using the DOM delivered with Xerces 2.6.2.
Before I'll send the generated xml-document through network to another system I have to check with my xml-schema if the document is correct.
In the DOM-FAQ I found an "example" trying to explain how it should work. But with this example the problems begin.
I am creating my document with this method:
public void createDocument() {
myDOM = DOMImplementationImpl.getDOMImplementation();
doc = myDOM.createDocument("", "documentData", null);
root = doc.getDocumentElement();
root.setAttribute(
"xmlns:xsi",
"http://www.w3.org/2001/XMLSchema-instance");
// root.setAttribute("xsi:noNamespaceSchemaLocation", "myScheme.xsd");
domConfig = ((DocumentImpl) doc).getDomConfig();
domConfig.setParameter(
"schema-location",
"file:///d:/workspace/XMLProject/WebContent/WEB-INF/myScheme.xsd");
domConfig.setParameter("error-handler", new EHandler());
domConfig.setParameter("validate", Boolean.TRUE);
}In the line getting the domConfig, it is getting differeing to the example: The example is like this:
import org.w3c.dom.Document;
import org.w3c.dom.DOMConfiguration;
import org.w3c.dom.ls.LSParser;
Document document = builder.parseURI("data/personal-schema.xml");
DOMConfiguration config = document.getConfig();
config.setParameter("error-handler",new MyErrorHandler());
config.setParameter("validate", Boolean.TRUE);
document.normalizeDocument();They get the DOM-Configuration from the document-Object, but my document-Object has no "getConfig()" and only after type-casting I get a getDomConfig()-Method to get the configuration.
Then I fill my document and call
((DocumentImpl) doc).normalizeDocument();When I run my Application I get the following error:
org.w3c.dom.DOMException: FEATURE_NOT_SUPPORTED: The parameter schema-location is recognized but the requested value cannot be set.
at org.apache.xerces.dom.DOMConfigurationImpl.setParameter(Unknown Source)
at xmlProject.createDocument(Convert.java:63)
at xmlProject.Convert.main(Convert.java:154)I tried several ways to get the validation without success.
The next question is how I should refer to my xml-schema (which path) and where to place it relative to my jar I will generate, because I will have no webserver I could place it on.
Has anyone any experience with validating a document created and not placed on disc?
I have also another question to SAX: I read, that it is reading a document without saving it in the memory. I think this means that if I am validating it by SAX it will be read once and for parsing it will be read a second time. If I would transfer the document over an tcp-connection, I only have the document once in my inputstream and after validation it would be consumed I think. But what can I parse then? Or did I missed a detail with the function of the SAX?
Thank you for your help!

Creating XML Schema from tables With Constraints
Greetings,
I'd have an interesting question. I finally am getting familiar with the various kinds of xml solutions provided by the oracle database, but hey here I have another interesting question I can't seem to get into life. I'm currently generating XML Schemas (XSD) from the tables of my database. Its nice its cool however I'd need to have the table's constraints with the xsd:elements also. And heres my problem, I can't seem to insert the table constrains. I'll show you what I mean:
<xsd:element name="MESSAGE_TABLE">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="MESSAGE_RECORD">
<xsd:complexType>
<xsd:all>
<xsd:element name="ID" type="xsd:integer" minOccurs="1" />
<xsd:element name="HEADER">
<xsd:simpleType>
<xsd:restriction base="xsd:string>
<xsd:maxLength value="255" />
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
</xsd:all>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
<!-- I'd need some more things here like... -->
<!-- Primary key(s) -->
<xsd:key name="PK_ID_PRIM">
<xsd:selector xpath="." />
<xsd:field xpath="ID" />
</xsd:key>
<!-- Foreign key(s) -->
<xsd:keyref name="FK_HEADER_FOREIGN" refer="PK_HEADER_ID">
<xsd:selector xpath="HEADER" />
<xsd:field xpath="ID" />
</xsd:keyref>
<!-- Unique constraint(s) -->
<xsd:unique name="UQ_..." ... />
</xsd:unique>
</xsd:element>That would fit my business needs, however I may be so blind that I can't see the forest from the tree. Currently I got so far that:
xmlElement
"xsd:schema",
xmlAttributes
'http://www.w3.org/2001/XMLSchema' as "xmlns:xsd"
xmlElement
"xsd:element",
xmlAttributes
target_table as "name"

'unbounded' as "maxOccurs"

xmlAgg(ELEMENT)
xmlElement

)As you can see this won't be good since I have put a single xml element in there. I guess I'd need something more like an xmlAgg(CONSTRAINTS), however in that case I'm wondering how will the select's FROM part look like.

XML schemas in subfolders problem
We have a large number of XML schemas and have partitioned them into different folders. This means that imported schemas are often located in a relative directory e.g.
<import namespace="http://www.xyz.com/schema/Staff" schemaLocation="../../Staff.xsd"/>
However, when building a BPEL app in JDeveloper, the JDeveloper Web Content/Miscellaneous Files folder doesn't seem to have the facility to create sub-folders and I get validation errors when importing the schema alongside the ones it imports. I'm not an expert JDeveloper user - is there something I've missed?
thanks AshThanks, but actually I've yet to find that problem, as I haven't even got to creating any jars or anything yet. To clarify:
Simply using the "Import" button in the BPEL structure window in JDeveloper, you get a single prompt to browse for a schema.
Once imported, it ends up in a Web Content/Miscellaneous Files folder alongside every other schema. So I get JDeveloper flagging errors because my schema references other schemas relative to directory folder e.g. "../../ref.xsd". -
I was wondering what size restrictions there are on XML schemas? I'm developing a schema that has just raised the following error on registration.
ERROR at line 1:
ORA-31084: error while creating table "CAS"."swift564357_TAB" for element "swift564"
ORA-01792: maximum number of columns in a table or view is 1000

ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 151
ORA-06512: at line 828
On removing a few elements from the schema it registers fine, but querying the generated table swift564xxx_TAB there is only ever one column, typed with an ADT that itself only has 5 elements. In fact there doesn't seem to be, on the face of it, any type that has more than 20-30 elements. Where does this error come from then?
Unfortunately the schema exceeds the 20k limit on postings. I can split it up and post it in two parts if this would help.
Thanks

Here's a snippet from the next version of the doc that may help...
3-20 Oracle XML DB Developer’s Guide, Rel. 1(10.1) Beta 2 Draft
A number of issues can arise when working with large, complex XML Schemas.
Sometimes the error "ORA-01792: maximum number of columns in a table or view
is 1000" will be ecountered when registering an XML Schema or creating a table
based on a global element defined by an XML Schema. This error occurs when an
attempt is made to create an XMLType table or column based on a global element
and the global element is defined as a complexType that contains a very large
number of element and attribute definitions.
The errors only occurs when creating an XMLType table or column that uses object
relational storage. When object relational storage is selected the XMLType is
persisted as a SQL Type. When a table or column is based on a SQL Type, each
Registering an XML Schema with Oracle XML DB
attribute defined by the Type counts as a column in the underlying table. If the SQL
Type contains attributes that are based on other SQL Types, the attributes defined
by those Types also count as columns in the underlying table. If the total number of
attributes in all the SQL types exceeds the Oracle limits of 1000 columns in a table
the storage table cannot be created.
This means that as the total number of elements and attributes defined by a
complexType approaches 1000, it is no longer possible to create a single Table that
can manage the SQL Objects generated when an instance of the Type is stored in the
database.
In order to resolve this problem it is necessary to reduce the total number of
attributes in the SQL Types that are used create the storage tables. Looking at the
schema there are two approaches that can be used to achieve this:
The first approach uses a ’top-down’ technique that uses multiple XMLType
tables to manage the XML documents. This technique reduces the number of
SQL attributes in the SQL Type heirarchy for a given storage table. As long as
none of the tables need manage more than 1000 attributes the problem is
resolved.
The second approach uses a ’bottom-up’ technique that reduces the number of
SQL attributes in the SQL Type herirarchy collapsing some of elements and
attributes defined by the XMLSchema so that they are stored as a single CLOB.
Both techniques rely on annotating the XML Schema to define how a particular
complexType will stored in the database.
In the case of the top down techniqueby the annotations SQLInline="false" and
defaultTable are used to force some sub-elements within the XML Document to
be stored as rows in a seperate XMLType table. Oracle XML DB maitains the
relationship between the two tables using a REF of XMLType Good candidates
for this approach are XML Schemas that define a choice where each element
within the choice is defined as a complexType, or where the XML Schema
defines an element based on a complexType that contains a very large number
of element and attribute definitions.
The bottom up technique involves reducing the total number of attributes in the
SQL object types by choosing to store some of the lower level complexTypes as
CLOBs, rather than objects. This is acieved by annotating the complexType or
the usage of the complexType with SQLType="CLOB".
Which technique is best depends on the application, and the kind of queries and
updates that need to be performed against the data. -
Hi,
when I bind a form to a XML schema, what ever changes to the XML schema like the max length, will it be reflected in the form? Seem like it is not. I have to delete the existing data connection and created a new data connection, and rebind the XML to the form items. What if there is many changes to the XML, all the items will have to be rebinded? Oh...:(@ Edgar_van_Waardenburg:
"You actually create a new form-field, which automatically inherits its type and properties from the related data type AT THAT MOMENT"
As quoted above from your reply, do you mean that what type of control is generated for a xml element is defined as type in the schema?
When i make a dataconnection using a schema file(.xsd), all my elements are shown as TextField. While I need some radio buttons and checkboxes etc...
Can i know how to specify the type in schema so that different types of controls can be generated? Below is my schemal defination.

Hi all,
Long time ago, I manually created a Database (APGriMMRP) and 3 Tables (dbo.Table_1_XYcoordinates, dbo.Table_2_Soil, and dbo.Table_3_Water) in my SQL Server 2012 Management Studio (SSMS2012). The dbo.Table_1_XYcoordinates has the following columns: file_id,
Pt_ID, X, Y, Z, sample_id, Boring. The dbo.Table_2_Soil has the following columns: Boring, sample_date, sample_id, Unit, Arsenic, Chromium, Lead. The dbo.Table_3_Water has the following columns: Boring, sample_date, sample_id, Unit, Benzene, Ethylbenzene,
Pyrene. The dbo.Table_1_XYcoordinates is a Parent Table. The dbo.Table_2_Soil and the dbo.Table_3_Water are 2 Child Tables. The sample_id is key link for the relationship between the Parent Table and the Child Tables.
Problem #1) How can I print out or export these 3 dbo Tables?
Problem #2) If I right-click on the dbo Table, I see "Start PowerShell" and click on it. I get the following error messages: Warning: Failed to load the 'SQLAS' extension: An exception occurred in SMO while trying to manage a service.
--> Failed to retrieve data for this request. --> Invalid class. Warning: Could not obtain SQL Server Service information. An attemp to connect to WMI on 'NAB-WK-02657306' failed with the following error: An exception occurred in SMO while trying
to manage a service. --> Failed to retrieve data for this request. --> Invalid class. .... PS SQLSERVER:\SQL\NAB-WK-02657306\SQLEXPRESS\Databases\APGriMMRP\Table_1_XYcoordinates> What causes this set of error messages? How can
I get this problem fixed in my PC that is an end user of the Windows 7 LAN System? Note: I don't have the regular version of Microsoft Visual Studio 2012 in my PC. I just have the Microsoft 2012 Shell (Integrated) program in my PC.
Problem #3: I plan to create an XML Schema Collection in the "APGriMMRP" database for the Parent Table and the Child Tables. How can I handle the relationship between the Parent Table and the Child Table in the XML Schema Collection?
Problem #4: I plan to extract some results/data from the Parent Table and the Child Table by using XQuery. What kind of JOIN (Left or Right JOIN) should I use in the XQuerying?
Please kindly help, answer my questions, and advise me how to resolve these 4 problems.
Thanks in advance,
Scott ChangIn the future, I would recommend you to post your questions one by one, and to the appropriate forum. Of your questions it is really only #3 that fits into this forum. (And that is the one I will not answer, because I have worked very little with XSD.)
1) Not sure what you mean with "print" or "export", but when you right-click a database, you can select Tasks from the context menu and in this submenu you find "Export data".
2) I don't know why you get that error, but any particular reason you want to run PowerShell?
4) If you have tables, you query them with SQL, not XQuery. XQuery is when you query XML documents, but left and right joins are SQL things. There are no joins in XQuery.
As for left/right join, notice that these two are equivalent:
SELECT ...
FROM a LEFT JOIN b ON a.col = b.col
SELECT ...
FROM b RIGHT JOIN a ON a.col = b.col
But please never use RIGHT JOIN - it gives me a headache!
There is nothing that says that you should use any of the other. In fact, if you are returning rows from parent and child, I would expect an inner join, unless you want to cater for parents without children.
Here is an example where you can study the different join types and how they behave:
CREATE TABLE apple (a int NOT NULL PRIMARY KEY,
b varchar(23) NOT NULL)
INSERT apple(a, b)
VALUES(1, 'Granny Smith'),
(2, 'Gloster'),
(4, 'Ingrid-Marie'),
(5, 'Milenga')
CREATE TABLE orange(c int NOT NULL PRIMARY KEY,
d varchar(23) NOT NULL)
INSERT orange(c, d)
VALUES(1, 'Agent'),
(3, 'Netherlands'),
(4, 'Revolution')
SELECT a, b, c, d
FROM apple
CROSS JOIN orange
SELECT a, b, c, d
FROM apple
INNER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM apple
LEFT OUTER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM apple
RIGHT OUTER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM apple
FULL OUTER JOIN orange ON apple.a = orange.c
go
DROP TABLE apple, orange

How can i change a xmltype column's xml schema?
i create a table that have a xmltype column.this column is schema-based.
my problem is ,
now i want to this column's schema will be redefined to a global schema?
[b]how can i change the column's schema which already have a schema?When a schema is registered a lot of additonal annotations are added to the XML schema by the schema registration process - Look at the version of the XML schema under /sys/schemas/... in the XML DB repository. This information is unqiue to that version of the XML schema and is used internally to manage instance level metadata.
When instance documents are stored in the DB a set of metadata is generated for each document so that we can make sure that we can maintain DOM Fidelity. This metadata is tied directly to the XML schema the document is associated and is only valid in the context of that XML Schema.
So when the schema is registered locally and instances are stored the generated metadata is only valid in the context of the local schema. If the same schema is now registered globally new values will be generated for the annotations applied to the global version of the XML schema. Consequently the metadata associated with a document belonging to the local version of the XML schema has no meaning when viewed in the context of the global version of the XML schema.
The net effect of this is that you will need to copy the data in order to get documents where the metadata for each document is based on the global version of the XML SChema. -
XML Schema Generated By XMLSpy fails validation in JDev 10.1.3.0.4
Hi gurus,
I am trying to view an XML schema generated by XMLSpy in JDev 10.1.3.0.4 but got this error:
Error(6,74): <Line 6, Column 74>: XML-24523: (Error) Invalid value 'simpletypes\AmendmentReasonChargeType.xsd' for attribute: 'schemaLocation'
Now in the XML schema, there is this line that causes the above error:
<xs:include schemaLocation="simpletypes\AmendmentReasonChargeType.xsd"/>
The same XML schema can be opened in Visual Studio 2003 OK. Could anyone help me out here? Thank you!
BenThere is a tool tip that displays over the line that causes the error and this is what it says,
value of attribute schemaLocation not of anyURI type. The value must be of the following type:
Type Name: anyURI Primitive Type: anyURI
What does it mean?
Thanks

Problems using mathml XML Schema in XMLDB
I have successfully loaded the hierarchy of XML Schema definition documents for the current 'mathml' by adjusting the relative paths in all include and import statements, and by forcing the load to overcome cyclic dependency issues.
However when I try to create a table using the XMLTYPE or register another schema which is dependent on mathml I receive the following error:
ERROR at line 1:
ORA-31079: unable to resolve reference to group "Content-expr.class"
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 37
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 61
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 126
ORA-06512: at line 14
Having tried loading into both 9iR2 and 10GR2 databases and pasting the document containing the 'Content-expr.class' into the parent document (i.e. removing the include) I have come to the conclusion that there is a problem with the schema definition.
However being new to XML I do not know what ths issue is as the file containing the definition (math.xsd) is included well before the references in the parent document.
Here is the group definition corresponding to the offending reference:
<xs:group name="Content-expr.class">
<xs:choice>
<xs:group ref="ContExpr.class"/>
<xs:group ref="PresExpr.class"/>
</xs:choice>
</xs:group>
I am also unable to trace which reference is causing the problem as there are several.
Does anyone have any suggestions as to what could be causing this issue, or how I can obtain further diagnostics?
Any help much appreciated.
Robert Honeyman
*********** New info ***************
OK. I have tried further to register the schema, and have the following additional information.
I determined that I thought my problem was cyclic dependencies being resolved ONLY by virtue of the parent file mathml2.xsd. I therefore pasted all the files together in include order so that this was no longer an issue. I then performed the following actions:
1. I tried to register into Oracle 9iR2 database (9.2.0.4) and received the following error:
ERROR at line 1:
ORA-31151: Cyclic definition encountered for group: "Content-expr.class"
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 0
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 26
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 131
ORA-06512: at line 14
2. I then tried registering the schema into an Oracle 10G Release 2 database as well, and received the following error:
ORA-31084: error while creating table "MEDLINE"."math729_TAB" for element
"math"
ORA-01792: maximum number of columns in a table or view is 1000
ORA-02310: exceeded maximum number of allowable columns in table
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 37
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 61
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 126
ORA-06512: at line 14
My conclusions are as follows:
1. 9iR2 (the version I was using at least 9.2.0.4) can't handle cyclic dependencies at all, or at least not complex ones.
2. Neither 9iR2 or 10gR2 can handle cyclic dependencies (or other dependent definitions managed purely by virtue of a parent file with multiple include statements)
3. 10gR2 can handle cyclic dependencies when they are all defined in the same file or resolved by an explicit include regardless of complexity.
4. 10gR2 cannot handle highly complex XML Schema definitions due its limit of 1000 columns per table.
Does anyone have any comments on these conclusions?
I don't even want to handle Mathml, just another schema definition that imports it. I may try to make my own adjustments.

nullThanks, I found the relevant sections in the XML DB 10GR2 documentation (chapter 3 I think). As far as I can tell my options are to either use one of the following:
- top-down technique creating tables for sub elements in the schema definition
- bottom-up technique collapsing some of the lower elements into CLOBs (I guess this is semi-structured storage)
The problem with Mathml is that it seems quite complex, with only one global schema element and many nested elements, hence only one table is created by XMLDB and it logically follows that we run out of columns.
To get it to work is likely to involve a fair amount of manual schema modification, which incurs a maintenance overhead for me.
It would be good if Oracle could provide a way of simplifying this maintenance of complex schemas to get them to be registered. I guess this would be increasing the number of columns alllowed for a table or offering some other parametric option for DBMS_XMLSCHEMA.REGISTER_SCHEMA that allowed a threshold and either a top-down or bottom-up approach to be taken automatically.
For the time being I am using a simplified schema that does not depend on Mathml for my storage needs.
