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,
-Jeff

Using extractvalue with XMLTYPE to extract multiple nodes
hi ,
I'm trying to fetch data from xml which is stored as clob in db (10g) ,
when i tried to fetch with query as below
SELECT extractvalue(XMLTYPE(xjm.X_MSG_XML), '//orderRequest/order/orderItem/alternativeIdentifer/value') uiid
FROM TABLE_X_MSG_ATTR xma, TABLE_X_JMS_MSG xjm
WHERE xma.X_MSG_ATTR2X_JMS_MSG=xjm.OBJID
AND xma.X_ATTR_NAME='MOP_ID'
AND xma.X_ATTR_VALUE in ('RJM78999')
and got **ORA-19025: EXTRACTVALUE returns value of only one node**
so i modified it as below
SELECT extractvalue(value(x), '//orderRequest/order/orderItem/alternativeIdentifer/value') uiid
FROM TABLE_X_MSG_ATTR xma, TABLE_X_JMS_MSG xjm
,TABLE(XMLSequence(extractvalue(XMLTYPE(xjm.X_MSG_XML),'//orderRequest/order/orderItem/alternativeIdentifer/value'))) x
WHERE xma.X_MSG_ATTR2X_JMS_MSG=xjm.OBJID
AND xma.X_ATTR_NAME='MOP_ID'
AND xma.X_ATTR_VALUE in ('RJM78999')
ORA-29900: operator binding does not exist
ORA-06553: PLS-306: wrong number or types of arguments in call to 'XMLSEQUENCE'
no success :( it is working for single record (node)all perfect

Edited by: Volution2111 on Sep 11, 2010 5:10 AMDifficult to give the exact answer without knowing which node repeats..
Howver it will be something like this
select extractValue(value(x),'/RepeatingNode/NonRepatingNode/NonRepeatingNode)
from TABLE, table(xmlsequence(extract(xmltype(clob),'/Root/Node/RepeatingNode')))) x -
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
|_PickData381_T
|___ProdRun382_T
|_____PickWave388_COLL
|_______PickWave383_T
|_________Customer387_COLL
|___________Customer384_T
|_____________InvOrder386_COLL
These objects are then used in the following nested tables:
TABLE_NAME TABLE_TYPE_NAME PARENT_TABLE_NAME PARENT_TABLE_COLUMN
SYS_NTaK/5zar5S0WitSsgu6OKPQ== PickWave388_COLL PickData389_TAB "XMLDATA"."ProdRun"."PickWave"

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

hi all,
i've recently implementing a project which need to stored hierarchical data. since relational db alone can only offer flatfile and implementing hierarchical data using realtional table with design structure such as
1. MPTT(Modified Preorder Tree Traversal)
2. Adjacency List
3. Recursion
has a lot of drawback ESPECIALLY on searching/traversing to find parent nodes. so i decided to try using oracle xmldb since xml is by nature hierarchical. so i came out with a design by using relational table + xmltype column. what i did is for eg. a customer table
create table customer(
id varchar2(32),
name varchar2(50),
balance number,
xmltype
the xmltype is stored as schema enabled not Clob. the schema is defined where the customer node will have unlimited nesting with each other.
where the xmltype column is to stored the position/path of this customers within xml tree.
eg. This customer id is 3 and the path is stored as below
<root>
<customer id="1">
<customer id="2">
<customer id="3"/>
</customer>
</customer>
</root>
the path will have a root node element and nested all the way until this customers. so in short i will be able to select this customer using Xpath, by traversing up by grabbing all the parents, getting all the child of this customer and getting the sibling as well.
the operation on this row record will involved with updating or querying(mostly) the xmltree inside this column.
so, my question is, based on this design:
1. is this design relevent? compared to just used MPTT(Modified Preorder Tree Traversal), Adjacency List & Recursion?
2. which isolation level should i use if there's an event that this customer's path will be updated/or the parent nodes need to be updated?
i'm not very sure about this design yet, so any recommendations or advise on this?
Thanks & Regards,
wesleyYou will need to create a custom BC4J domain object as a java type for XMLType and then implement the necessary fetch and update semantics. There is no built in support in BC4J framework for this type at this time.

Issues with using XMLType indexes against a table with XMLType column
I am attempting to use an XMLIndex with a Structured Component and not having too much luck. Not much data in metalink nor is the documentation very helpful:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10492/xdb_indexing.htm#BCGHGIGC
The table DDL is as follows:
CREATE TABLE ECI_SCHEMA.REV_ITEM_EARN_DTL_VIRTUAL(
REV_ITEM_EARN_DTL_ID_NBR NUMBER(16,0) NOT NULL,

According to the documentation, I should be able to create a structured XMLIndex on the XMLType column with the following syntax:
SQL> create index eci_schema.rev_item_earn_dtl_virt_xmlix on eci_schema.rev_item_earn_dtl_virtual
2 (INV_DTL_IMG)
3 INDEXTYPE IS XDB.XMLIndex
4 parameters ('PATH TABLE RIED_PATH_TABLE')
5 local;
When I do this, I get the following error:
create index eci_schema.rev_item_earn_dtl_virt_xmlix on eci_schema.rev_item_earn_dtl_virtual
ERROR at line 1:
ORA-29958: fatal error occurred in the execution of ODCIINDEXCREATE routine
ORA-30959: The indexed column is not stored in CLOB.
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

/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.

Issue with extractvalue from table with XMLTYPE column.
I'm sure there is a simple answer but I am having problems
retrieving data from an xmltype column type.
I have two tables
descr dab_xmlName
TABLE of XMLTYPE
descr dab_testName
A NUMBER
AB NUMBER
DATA CLOB
DATA2 VARCHAR2(1600)
MYXML XMLTYPE
I have inserted the Oracle example XML purchaseOrder.xml into both dab_xml
and the myxml column in dab_test.
When I run the following:
SELECT extractvalue(OBJECT_VALUE, '/PurchaseOrder/Reference')
FROM dab_xml;
SBELL-2002100912333601PDT is returned
When I run this:
SELECT extractvalue(OBJECT_VALUE, '/PurchaseOrder/Reference')
FROM (select myxml from dab_test);
ERROR at line 1:
ORA-00904: "OBJECT_VALUE": invalid identifier
Why are the two different?
Any help will be appreciated.
Regards,
DavidIn short you want
SELECT extractvalue(myxml, '/PurchaseOrder/Reference')
FROM dab_test;This difference is that for dab_xml, there are no columns defined for the table, therefore you are [OBJECT_VALUE|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/pseudocolumns006.htm#sthref830] as an alias for a non existent column.
With dab_test, you have a column that contains the XML so you need to use that column name instead of OBJECT_VALUE. -

see the doc,
Re: how to make xml schema change when there are existing records in the ta
However, our requirement is different in the following ways:

want( all structured storage, but with different schemas).
2. When a XMLTYPE Schema needs to be updated, we will add a new
xmltype column, assign it the new schema and migrate the data from the old column. After that we want to drop the old xmltype column and it's schema to reclaim all the storage.
The underlying xml tables are drop, space reclaimed.
However, we found out that the segment/blocks/bytes of the xmltype column itself is not released.
Question:
1. Since Xmltype column associated with xmltype schema is structured
stored, the xmldoc should parsed and stored in underlying tables. However, it seems that the xmltype column itself is acquiring sunstantial amount of space.
By querying user_segments table, we saw the underlying structure is actually taking constant and small space, however, the main table is taking huge space.(We populated the table with 61K rows), For instance,
SEGMENT_NAME BYTES SEGMENT_TYPE
PERFORMANCEEVENT 260046848 TABLE
SYS_C007080275 1048576 INDEX
Performance1833_TAB 65536 TABLE
Date1831_TAB 65536 TABLE
LocationAddress1814_TAB 65536 TABLE
SYS_IL0010401244C00018$$ 65536 LOBINDEX
SYS_IL0010401244C00012$$ 65536 LOBINDEX
Where PERFORMANCEEVENT is the main table.

This will give you an idea about the way and when xml is shred into tables.
XMLType column based on XML Schema: several questions
In your case since you are not using the default table, the data is stored witin the table itself as oracle has not shred the data. -
How to use SQL*Loader to load XMLType Column with other columns?
Hi,
I am trying to use sqlldr to load an XML file into a table with an XMLType column. I have found plenty of examples where the entire table is an xmltype, but I would like to load many XML objects into a generic table for processing with one XMLType column and many other columns to identify the load. As a simple example, I have one constant column which I want to set during the upload.
The following example does not work :(. No errors either.
create table xml_upload
(upload_type varchar2(10) not null,
xml_data XMLType)
my control file:
LOAD DATA
INFILE * append
INTO TABLE xml_upload
XMLType(xml_data)
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
upload_type constant MARKET,
xml_data
BEGINDATA
<SALE_ORDER>
<CUST_CODE>TIM</CUST_CODE>
<ORDER_NUM>1234></ORDER_NUM>
</SALE_ORDER>
$ sqlldr my.ctl

Any ideas on how I can do this? Am I missing something...
I have also been playing with the lobfile clause of sqlldr, also without any success...
Current database version is 10g R2.
Thanks,
Tim.Hi,
I tried the same example as it is. but, I am getting the following error:

Difficulty extracting from XMLTYPE column using XMLTABLE
Hi Folks.
I am currently trying to shred the contents of an XML document that is stored on our schema in a XMLType column. The XMLYTYPE column is pointing to several schemas that are registered within the database.
If I take a subset of the XML from one of the files and create an XMLTYPE column on the fly, I am able to extract data using the XMLTABLE syntax. If I try the same thing on the XMLTYPE column in the table registered to schemas stored in the database I get no joy.
Please see below for an example.
Please note that this is only a small segment of the original XML document which is very large. The XML document has one <RTDRFileHeader> and <ConnectionList> nodes per document but many <Connection> nodes beneath the <ConnectionList>.
My requirement is to RETRIEVE ALL the data contained in the <Connection> elements beneath the <ConnectionList>. How do I achieve this?

How to upload as one row in xmltype column using sqlloader
I have the file test.xml which has data as shown below
<?xml version="1.0" encoding="ISO-8859-1">-<ops> <op><op_type>A</op_type><ent_type>A</ent_type></op>
<op><op_type>A</op_type><ent_type>A</ent_type></op>
</ops>
I need the entire data to be loaded as one row to a xmltype column.
How can I do this using sqlloader?
I tried the following, but it works only if everything is in one line.
LOAD DATA
INFILE 'test.xml'
INTO TABLE poc
(content char(1000) ENCLOSED BY '<ops>' AND '</ops>')
Is there an EOF option?XML questions (and answers) are better suited to the XDB forum...
XML DB
But in answer to your question, I don't think sqlloader is the best tool to be using for loading XML data into your database. The XDB forum has loads of examples of how to load XML into database tables. -
The simplest way to get more performance on select on xmltype column?
We have a table with xmltype column:
CREATE TABLE "TK"."PLAN_2" ("UNID" NUMBER NOT
NULL,
"XMLSTRING" "TK"."XMLTYPE",
CONSTRAINT "SYS_C001142583" PRIMARY KEY("UNID")
USING INDEX
TABLESPACE "TX"
STORAGE ( INITIAL 64K NEXT 0K MINEXTENTS 1 MAXEXTENTS
2147483645 PCTINCREASE 0) PCTFREE 10 INITRANS 2 MAXTRANS 255)
The data in column xmlstring looks like this:

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.

How to create index on a xmltype column stored as CLOB
actually i have two problems.
i uploaded this schemaA.xsd file into xmldb repository without problems. registration also went ok.
BEGIN
DBMS_XMLSCHEMA.registerSchema(
schemaURL => 'http://xmlns.example.com/xdb/documentation/schemaA.xsd'
,schemaDoc => sys.UriFactory.getUri('/home/dev/schemaA.xsd')
,local => TRUE
,genBean => false
,genTypes => TRUE
,genTables => false
,enableHierarchy => DBMS_XMLSCHEMA.ENABLE_HIERARCHY_NONE
END;
then i run this:
create table pf_table_a(
id VARCHAR2(100) primary key,
xsd VARCHAR2(3000),
xml_document XMLType
) XMLTYPE COLUMN xml_document
STORE AS CLOB
XMLSCHEMA "http://xmlns.example.com/xdb/documentation/schemaA.xsd"
ELEMENT "order";
and got this error:
SQL> @d:\usr\dev\perftest\create_tables.sql
Table created.
create table pf_table_a(
ERROR at line 1:
ORA-00955: name is already used by an existing object
anyway the table was created. so i went on to create indexes.
SQL> create index pf_a_index on pf_table_a(extractValue(OBJECT_VALUE, '/order@or
derNo'));
create index pf_a_index on pf_table_a(extractValue(OBJECT_VALUE, '/order@orderNo
ERROR at line 1:
ORA-04063: table "BAUSER1.PF_TABLE_A" has errors
this of course is wrong. because the command is for creating index of a XMLTYPE table. no a column. but what is the correct command? thanks.

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?

Bug in SQL Developer relating to handling of XMLTYPE columns
Hi,
I have found a bug in SQL Developer relating to its handling of XMLTYPE columns.
Given a table with the following data:
ID, XML_DATA
1, <xml here>
2, <xml here>
3, <xml here>
And the following SQL to extract a value from the XML and also an XML fragment as an XMLTYPE:
SELECT
EXTRACTVALUE(t.column_value,'/*/USER_ID/text()')user_id
, t.column_value user_data
FROM dbuser.mytable m
, TABLE(XMLSEQUENCE(EXTRACT(m.xml_data, '/*/USER_LIST/USER'))) t
I get the following:
user_id, user_data
jsmith26, (XMLTYPE)
mjones45, (XMLTYPE)
sborga31, (XMLTYPE)
Note that the user_id is correctly extracted, however the XMLTYPE column (user_data) is empty in SQL Developer.
The same query returns the correct XML data in TOAD.
Edited by: 1008733 on May 29, 2013 5:07 PMSteve,
So your example is slightly more complex than the one documented for a table in the standard OE schema here:
http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions052.htm
That example works fine on an 11.2.0.1 database with SQL Developer 3.2.20.09.87. Please try the following with your case:
Tools -> Preferences -> Database -> Advanced -> Display Struct Value In Grid (check it off if not already)If that still does not work for Run Statement (query result displayed in the grid, not as script output using Run Script), then please provide a test case based on the Warehouse table in the OE schema (or your case with DDL and DML scripts including the xml data) and I will log a bug.
Thanks,
Gary

Problem query of XMLType column in XSQL servlet
Hi all,
I'm having trouble debugging the following error from a query on an XMLType column in an XSQL page query:
<page xmlns:xsql="urn:oracle-xsql" connection="jdbc/DBConnection1DS">
<xsql:query max-rows="1" null-indicator="no">
SELECT extractValue(x.DOCBOOKS_DOC, '/book/part/title', 'xmlns="http://docbook.org/ns/docbook"') "BOOK TITLE"
FROM DOCBOOKS_STORE x
</xsql:query>
</page>
which returns the following error message:
<page>
<ERROR>
oracle.xml.sql.OracleXMLSQLException: Character ' ' is not allowed in an XML tag name.
</ERROR>
</page>
The SQL query works fine in the SQL Worksheet and SQL Plus, only when I stick it in an XSQL query. I've tested the XSQL Page environment with a query on Number Datatype column and no issues there either.
Any suggestions, much appreciated. Thanks.
GeorgeThe XML SQL Utility creates XML tags named after your column aliases.
You have aliased the column to a name containing a space: "BOOK TITLE"
This error is telling you that the implied XML element whose name matches this column alias, which would be <BOOK TITLE> is not a legal name for an XML element since it has a space in it.
You'll need to pick a column alias with no space in the name. For example, "BOOK_TITLE" and then in your XSLT stylesheet (or whatever downstream formatting tool you may be using) remove the underscore from the name and replace it with a space.
