XMLType column selection
I have the following in an XMLType column:

When I run select extractvalue(CCD_DOC, 'recordTarget/patientRole/patient/name/family') from CCD; no errors are returned but I also don't get the value. What am I missing?
In a word - namespace definitions...
Here's an example written using XMLQuery, rather than extractValue, which is the preferred approach in 10.2.x and later...

Convert CLOB to XMLType in SELECT statement ?
Hi XML Xperts,
In my Oracle 9.2.0.3 I have 1 table (tab1) with 2 cols (col1 as XMLType and col2 as CLOB). I Inserted in both fields the following same XML data :
<?xml version="1.0"?>
<TABLE_NAME>MY_TABLE</TABLE_NAME>
With the following statement, I can get the data from col1 which is a XMLType column :
SELECT a.col1.extract('//TABLE_NAME/text()').getStringVal() AS "Table Name"
FROM tab1 a
WHERE a.col1.existsNode('/TABLE_NAME') = 1;
How to get the same data FROM col2 whcih is a CLOB column ? Is it possible to transform the CLOB to XMLType in the SELECT statement ?
Note : I cannot change the type of the colulmn col2 to XMLType
Thanks in advance.
PhilI tested it in 10g and it seems to be OK.
create table clobtoxml(xmldata clob);
insert into clobtoxml
values('<RootE><FirstNode>This is CLOB data to XML</FirstNode></RootE>');
commit;
select sys.xmltype(xmldata).extract('/RootE/FirstNode/text()').getStringVal() from clobtoxml;
This is CLOB data to XML
select sys.xmltype(xmldata).extract('/*') from clobtoxml;
<RootE>
<FirstNode>This is CLOB data to XML</FirstNode>
</RootE>

Select DISTINCT attribute vlaues fom XMLTYPE column and...
Hello
I have spent whole day to find the solution with no success. PLEAS HELP !
The Problem :
1. I have table with xmlType column in this column is the following xml:
<revision>
<product id = 1>
<screw>
<img id = 1/>
</screw>
<screw>
<img id = 2/>
</screw>
</product>
<product id = 2>
<screw>
<img id = 1/>
</screw>
</product>
</revision>
I must select DISTINCT img IDs and then select/join them form relational table img (id(number), pic (blob) )
I can't find the solution to select distinct attribute values from XML!
I have tried this:
select extract(c.xml, 'revision/product/screw/img[not(@id=preceding-sibling::img/@id)]/@id') from TABLE c;Hello Odie_63
I have again problem finally my XML looks that:
<revision>
<product id = "1">
<screw>
<img id = "1"/>
</screw>
<component>
<img id = "1"/>
</component>
<screw>
<img id = "2"/>
</screw>
<component>
<img id = "2"/>
</component>
</product>
<product id = "2">
<screw>
<img id = "1"/>
</screw>
<component>
<img id = "4"/>
</component>
</product>
</revision>'));
And I don't know why my following statement doesn't work. (I must slect all distinct id from <img>).
select distinct x.img_id
from cfg_xml t
, xmltable(
'/revision/definitions/product'
passing T.EQ_CFG_XML
columns img_id number path '/component/img/@id',
img_id2 number path '/screw/img/@id'
) x
And this is VERY SLOW :/
select x.img_id, y.img_id
from cfg_xml t
, xmltable(
'/revision/definitions/product/screw/img'
passing T.EQ_CFG_XML
columns img_id number path '@id'
) x,
xmltable(
'/revision/definitions/product/component/img'
passing T.EQ_CFG_XML
columns img_id number path '@id'
) y
Is it possible to return al distinct ID in one column>?
Thanks for HELP :)

We want to select on the 'ID', which occurs more than once in the xmlstring and the table gonna be big, so we think we need some kind of index on the ID-Identifier. What will be the best way to do this?Which version of Oracle (4 digits)?
If 10.2 or greater, look into using XMLTable and that is the replacement for the table(XMLSequence(extract()) approach. Also, avoid the use of // unless you really need it. I doubt it will make a difference in your situation but just a good performance approach in general.
We want to select on the 'ID', which occurs more than once in the xmlstringI assume you are going to want the count(...) > 1 from the XML to tell you which you are selecting?
I also have questions about what that XMLType is being stored as but that depends upon what your version is regarding what storage options you have.

Thanks for the assistance. I'm new to XML DB. I appreciate the help.
EricHi Eric,
You can use XMLExists, like this :
select *
from message t
where xmlexists(
'declare namespace env = "http://www.co.com/schemas/cfg-env/"; (: :)
declare namespace hdr = "http://www.co.com/schemas/cfg-hdr/"; (: :)
/env:Envelope/env:Header/hdr:MessageHeader/hdr:UserSession[hdr:LogonId=$id]'
passing t.message_content_txt
, 'R099999' as "id"
); -

What am I doing wrong? Based on the Oracle documentation, I was under the impression that 11.2 XMLIndex would work with Object Relational storage. Is this not the case?CREATE INDEX ECI_SCHEMA.REV_ITEM_EARN_DTL_IX7
ON ECI_SCHEMA.REV_ITEM_EARN_DTL
extractValue(inv_dtl_img, '/revenueInvoice/service/transportation/mstrTrkngNbr')

/Elements that occur at most once in each document can be indexed using extractValue(). Despite the fact that the index appears to be a functional index, when we create the index we automatically re-write the create index into a normal btree index on the column that contains the value for the element identified by the xpath.
Eg in the case of a functional index based on extractValue, defined on XMLType using Object relational storage, with an xpath that identifies a node that occurs at most once in each document is not a functional index, it's re-written into a plain old vanilla btree index. You can actually check this by looking in the system tables
Eg
SQL> connect system/oracle
Connected.
SQL> select table_name, index_name from all_indexes where owner = 'OE' and table_name = 'PURCHASEORDER';
TABLE_NAME INDEX_NAME
PURCHASEORDER LINEITEM_TABLE_MEMBERS
PURCHASEORDER ACTION_TABLE_MEMBERS
PURCHASEORDER SYS_C0011037
SQL> alter session set current_schema = OE
2 /
Session altered.
SQL> create unique index PO_REF_INDEX on PURCHASEORDER (extractValue(object_value,'/PurchaseOrder/Reference'));
Index created.
SQL> set lines 250
SQL> select index_name, index_type from all_indexes where owner = 'OE' and table_name = 'PURCHASEORDER';
INDEX_NAME INDEX_TYPE
PO_REF_INDEX NORMAL
LINEITEM_TABLE_MEMBERS NORMAL
ACTION_TABLE_MEMBERS NORMAL
SYS_C0011037 NORMAL
SQL> select * from dba_ind_expressions where table_name = 'PURCHASEORDER' and index_owner = 'OE'
2 /
no rows selectedFrom the above we can see that the index created on extractValue has been re-written in a plain old vanilla BTREE index, and there is no definition for it in dba_ind_expressions So assuming you were able to create the index and insert the data you should find that your index is not a functional index.

How to rename element (node) names in an XMLType column?
I have a source table with a xml data stored in an XMLType column.
The xml contains elements/nodes identified by numbers. I need to replace the numbers with the appropriate names.
The plsql below does this, but has two issues:
i. It selects the data into a clob and does a text replace on the elements in a loop. This works, but is super slow for 3500+ xml rows (about 500 node pairs per row).
ii. Once the data has had the element numbers replaced with the names, it inserts the new xml (clob wrapped in xmltype function) into the table with the XMLType attribute.
The problem with the latter action is that it is failing due to nls client vs server settings, or so it appears from what I could dig up. The actual error message:
ORA-19202: Error occurred in XML processing
LPX-00242: invalid use of ampersand ('&') character (use &)
Error at line 3
There are come entities in the original xml like "" (the degree symbol).
My question is two-fold:
a). Can I replace the element names without straying from the xmltype datatype? If so, how?
b). If I cannot do "a.)", then what must I do ensure that the clob gets converted correctly to xmltype and inserted into the table?

----code below-----
(note, this is a stripped down version of the original, so there may be typos)

l_newxml XMLType;
v_record_uid NUMBER(20);
CURSOR my_cur IS
select a.elementname,b.tagname
from t_elements a, t_tags b
where (a.element_uid = b.element_uid)
begin
select br.xml_data.getClobVal() xml_data into l_xmlclob from t_elements;
FOR my_rec IN my_cur LOOP
l_xmlclob := replace(l_xmlclob,my_cur.elementname,my_cur.maptag_name);
END LOOP;
l_newxml := XMLType(l_xmlclob);
insert into test_translated_xml (xml_data) values (l_newxml);
end;
(hopefully I haven't missed anything)
Any tips or hints would be much appreciated.
Thanks!Hello again,
Take a look at html entity codes: http://www.w3schools.com/tags/ref_entities.asp.
You can use this:
insert into t values (xmltype('<test>'||dbms_xmlgen.convert('this is a test &')||'deg;</test>'));
or
insert into t values (xmltype('<test>'||dbms_xmlgen.convert('this is a test &')||'#176;</test>'));
see this: ° (& deg;) or this: ° (& #176;)
SQL*Plus will not display degree character. But this is valid enitity code, and when you generate HTML out of this, it should be displayed properly in web browser.
HTML is in fact XML, that is validated by specific DTD (Document Type Definition).

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:
<?xml version="1.0" encoding="UTF-8"?>

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

|_____PickWave388_COLL
|_______PickWave383_T

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.

So, what I am looking for is a procedure loading this stuff in less than 2 minutes or possibly less.Does the following help

Ctxsys.context index on registered schema xmltype column
9iR2
Is it possible to create a text index (indextype is ctxsys.context) on a schema registered xmltype column?
I tried it, the index creation works fine.
After the first insert statement the Oracle process seems to hang. (CPU 100%, increasing memory consumption)Yes, I previously entered some data.
Test case:
1. register schema
begin
DBMS_XMLSCHEMA.REGISTERSCHEMA('http://localhost/JobPositionSeeker-1_1.xsd',
getDocument('JobPositionSeeker-1_1.xsd'), TRUE, TRUE, FALSE, FALSE
end;
2. create table
CREATE TABLE application_xml of XMLType
XMLSCHEMA "http://localhost/JobPositionSeeker-1_1.xsd" ELEMENT "JobPositionSeeker"
3. entered some data
4. created the index
create index applicant on application_xml ( SYS_NC_ROWINFO$)
indextype is ctxsys.context
5. select using index
select value(a).getClobVal() from application_xml a
where contains( value(a),'%ai% INPATH(//PersonalData/PersonName/FamilyName)')>0
6. insert another record
-> crash -
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

Regards,
ArghyadipHi 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>
<genre>Fiction</genre>

Problem reading a xmlType column (return only 999 rows) with XMLTable

OracleDataReader allocation using extractvalue() on XMLType column
I am accessing an element within an XMLType column in a select statement using the extractvalue SQL function.
Select ExtractValue(column_name,'//Text') from table_name
I noticed that the RowSize for the command used to execute the select is unusually large (~24K). I have narrowed the space allocation issue down to the extractvalue() column, which is about 8k per instance of extractvalue() in the select statement. Since the fetch size if 64K, I am seeing a lot of calls to opsDacRead (DB round trips?) in the ODP.NET log, probably due to the fact that only 3 rows are being returned in each call to opsDacRead.
My question is: How does ODP.NET determine the amount of space allocated within the reader's buffer for such a column? The element I am trying to extract is defined in the xml schema as 'xs:string' and is never more than 40 characters or so.Mark,
Thanks for the response.
Yes, I tried increasing FetchSize. Unfortunately, under heavy load, I experienced long execution/wait times within the first and last calls to opsDacRead() while walking the reader. I suspect that was due to allocation and clean-up.
However, I did find out why the buffer size was so large. If the xml schema does not contain length restrictions on string/text elements via the maxLength option, Oracle defines the underlying field in the data type created for the schema as VARCHAR2(4000).
I'm pretty sure that adding a maxLength restriction to the string element in the xml schema will reduce the size of the data type's field and in turn reduce the size of the Reader's buffer, but I haven't had a chance to test it.
Thanks again,

How to create index on XMLType column extension?
I have an XMLType column named "info" whose corresponding global element has a complexType "InfoType" in namespace "http://example.org/ord". The "InfoType" complexType is extended in two namespaces, "http://example.org/info/zipcode" and "http://example.org/info/street". How do I create a unique index using an "InfoType" element contributed from one of the extension namespaces?
I have included below a SQL script that completely describes the problem.
Thanks in advance for your assistance?
