Xquery XML Question on XMLType column

I have a table named invoiceaddrs described as:
desc invoiceaddrs;
Name Null Type
DATE_TIME DATE
RESPONSE XMLTYPE()
It captures responses from an external program which inserts the sysdate in the column date_time and the XML data in the column response.
I need to be able to use a query to view the data when statusSeverity="Error". I cannot find where Xquery is used to look at attributes in a XML tag and not the actual data.
How would I query to find records with statusSeverity="Error"?
Example of the XML when statusSeverity="Error":
<?xml version="1.0" ?>
<QBXML>
<QBXMLMsgsRs>
<InvoiceAddRs requestID="1" statusCode="3000" statusSeverity="Error" statusMessage="The given object ID "180000378-1187019437" in the field "list id" is invalid. " />
</QBXMLMsgsRs>
</QBXML>
I am using Oracle 11g.
Any help is appreciated.
Thanks,
Mike

Hi Mike,
you can use where clause inside the xquery
like this
.... xquery('for .....
where /QBXML/QBXMLMsgsRs/InvoiceAddRs/@statusSeverity="Error"
return ......) ...
I cannot find where Xquery is used to look at attributes in a XML tag and not the actual data.
if you want to know if the attribute exists or not then use
where /QBXML/QBXMLMsgsRs/InvoiceAddRs/@statusSeverity

How to insert large xml file to XMLType column?

Hi,
I have a table with one column as XMLType(Binary XML storage option and Free Text Indexing). When i try to insert a large XML as long as 8kb, i'm getting an error ORA-01704:string literal too long.
Insert into TEST values(XMLTYPE('xml HERE'));
How to insert large XML values to XMLType column?
Regards,
Sprightee

For a large XML file, you basically have two options - you can load the string directly as an XMLType, or you can load the string as a CLOB and cast it on the database side to an XMLType.
If you decide to load the XML as XmlType client-side, then you may be interested to know that versions of Oracle after 11.2.0.2 support the JDBC 4.0 SQLXML standard. See the JDBC driver release documentation here:
http://docs.oracle.com/cd/E18283_01/java.112/e16548/jdbcvers.htm#BABGHBCC
If you want to load as a CLOB, then you'll need to use PreparedStatement's setClob() method, or allocate an oracle.sql.clob object.
For versions before 11.2.0.2, you can create an XMLType with a constructor that includes an InputStream or byte[] array.

Oracle XQuery performance issue in XMLType column

Dear All,
As for oracle I'm using oracle 11g to measure the performance.
I'm using data from XMark project which is a >100MB data of XML for bencmarking purposes.
I make a table that contains an XMLType column and upload the data into that column, after doing that I try to do a query like this:
select xmlquery(
'for $i in /site/people/person
where $i/id = "person0"
return $i/name'
passing BookXMLContent Returning Content)
from Book;
The purpose of this query is to retrieve the name of a person that have id = 'person0'
My questions are:
1. Did I do something wrong with my query?
2. Is there any setting on the database that I should done prior to doing the query to done significantly better result?
3. Is there any other approach that are much better than I currently used?
Regards,
Anthony Steven

First, please read the licencing terms for Oracle ( And I suspect DB2, MSFT) . You are not allowed to publish externally (in any form, including forum posts :) ) the results of any benchmarking activities. I have edited your post accordingly. I hope this research is not part of a thesis or similar work that would intend making public as you and your institution would be in violation of your licence agreeement were you to do so.
Now back to your question, how can you improve performance for XMark
#1. Can you show us the create table statement you used, so we can see how you created your XMLType column BOOKXMLCONTENT.
#2. Did you create any indexes
#3. Did you look at the explain plan output.

Basic question - querying xmltype column

Hi,
Sorry for the basic question but please could someone paste in a working 'select where' statement which will pick out only those rows containing an element with specified content.
For example, how would I return n complete XML documents as query results for a situation where 'element_1' has text content 'apples'?
This does not seem to work:
SELECT x.xml_body.extract('/root_element/element_1/text()').getStringVal()
FROM xmltable x
WHERE x.xml_body.extract('/root_element/element_1/text()').getStringVal()='apples'

Hi Paul,
The query you have given works. I tried that query in the following format and it works.
Query 1:
SELECT x.xmlcol.extract(/Employee/Name/text()').getStringVal()
FROM table_name x
WHERE x.xmlcol.extract('/Employee/Name/text()').getStringVal()='Anu'
Query 2:
SELECT extractvalue(x.xmlcol,'//Name/text()')
FROM table_name x
WHERE extractvalue(x.xmlcol,'//Name/text()')='Srini'
Both the queries work. The xml is of the following format
<Employee company="Oracle">
<Name>Anu</Name>
<Department>OTN</Department>
<Location>India</Location>
</Employee>
Can you please tell the database version on which you are working?
For more information on XMLType you can refer the XMLDB Samples located at
http://otn.oracle.com/sample_code/tech/xml/xmldb/content.html
You can also refer to the XMLType Sample present at this location
http://otn.oracle.com/sample_code/tech/java/sqlj_jdbc/files/9i_jdbc/content.html#xmltype
to know how to work with XMLType columns.
You can get back to us if you have any more doubts.

How to insert 4K of XML data into XMLType column?

I use OCCI and our Oracle version is 9.2.0.1.0. I have successfully been able to insert xml data (any size) into a clob column using "insert into...values(.., empty_clob()) returning c1 into :3"; and then using Statement::GetClob() to acquire a reference to the internal clob and populate it. I cannot seem to be able to do the same when the column type is of XMLType.
I could not find a single sample code which demonstrates inserting into a table with a XMLType column. Using SetDataBuffer(OCCI_SQLT_STR) with data over 4000 bytes does not work.
I'd greatly appreciate any feedback.

Pretty sure this was a bug in the base 9.2 release which was fixed in a patch drop. Try 9.2.0.6 or later.

XML Schema based XMLType column leaves file open on error

Hello,
I have the following situation on both oracle 10.1.0.2.0 and 10.1.0.4.0:
insert into xml_products (xmlfile) values(bfilename(file_loc, char_id));
"xmlfile" is a xmltype column based on a registered xml schema.
When the file fails xml schema validation, the file remains open and I cannot move it until i close the session.
Is this a bug or an "intentional feature"?
Any workarounds?
Thanks,
Flavio

All right Mark,
thanks for your reply.
Meanwhile I fixed the problem and posted my workaround here:

2) This PL/SQL block works. However maximum raw size around 32K. The file can be around 100K. May be I can load it into a table of raw and somehow concatnate it to insert. Not sure whether this is possible but I am sure there must me a simple way of doing this.

How to insert large xml file ino xmltype column

Hi all,
iam using oracle10g. I have a table example1(key_column varchar2(10),xml_column xmltype) like this. i want to insert xml file from server to xmltype column. Can you please anybody suggest regarding this.wht is the size of the xmltype column. is it same as clob like 2GB or sth different. and one more thing is iam creating one procedure in that procedure , in that we are fetching xmltype value into clob varable. is it correct or not...
Thanks

Manipulating a single XMLType of 2GB is probably not sensible period. I'm guessing that the content of a file that big is probably a set of smaller XML documents which someone has wrapped a begin and end tag around. Since databases are good at handling collections of documents (or collections of anything else for that matter), you should consider de-compising the large document back into a set of smaller documents before storing it in the database

Updating the whole xml file in XMLType column

Hi ,
I am facing the problem in updating the XMLTYPE column.
I need to update the whole xml file
This is my table
SQL> desc EMPJAL_TABLE;
Name Null? Type
EMPLOYEEID NOT NULL VARCHAR2(140)
EMPCOM VARCHAR2(100)
EMPJAL SYS.XMLTYPE(XMLSchema "www.EMPSIM.com" Element "EMPJAL") STORAGE
Object-relational TYPE "EMPJAL_T"
I am able to form the CLOB object and trying to use this sql command
UPDATE EMPJAL_TABLE SET EMPJAL = XMLType( ? ) ) WHERE EMPLOYEEID ='emp1234';
Here I want to update the whole xmlfile in XMLTYPE column.
Error is - ORA-00933: SQL command not properly ended
Please advise
Thanks
Govinds

Hi Mark,
I apologise for this mistake. I am really putting lot of efforts and also worked/working in advance topics of XML DB.
Yes I am extensively using Oracle 10g r2 and suggesting others to use this
This time I had put more effort before posting ,I had a series of queries to resolve most of then were working , this was the one giving problem inside my java code
I am sorry for this .
Any how I made another query which works better.
Thanks
Govinda

HELP!!!!
Thanks,

I have made sure all my home settings are correct in my registry editor and they are. Another thing to note is the control file I am using works 100% perfectly, beautifully when called from Toad for Oracle. It is when called from the command line utility that it fails. Is there anyway to determine what the difference could be?
So we know that I can work (toad works), but it doesn't yet work in a "cmd" environment.
Just as any other program Toad is also a client and uses NLS and other environment settings. Maybe these are stored in the registry, maybe the are being set by Toad by reading a configuration file while it is started or while running.
As said, on Windows its tricky...
Setting properties in the registry will not mean that they are the same a "cmd" window or maybe not even been set.
If you execute / run "cmd" then the "set" statement/command will output the environment settings that will be used during the livetime of that "cmd" session.

...In the registry you can find a lot of those variables are set for ORACLE_HOME, ORACLE_BASE, SQLPATH, maybe TNS_ADMIN, ORACLE_SID, NLS_LANG. You can find the variables IN the registry on two places. The most common one is the SYSTEM wide environment settings under //HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE and in my case for 11.2 under //HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE/KEY_OraDb11g_Home1.
You could overrule this for to be active on "my user session", my login session as account "marco" under //HKEY_CURRENT_USER/Software/Oracle, but no one using Windows is doing this.
Besides the "cmd" and registry environment, there is a different place as well were you can set these parameters. In windows go to "start", click "control panel", click "system", click tab "Advanced" and then click on the button on the bottum with "Environment Variables". Here you can see the distinction between user and system wide variables as well. Here you can also set NLS_LANG, ORACLE_HOME etc. If I am not mistaken than these will be the default values used in a fresh "cmd" window session. But they can and will interfere with programs you start via clicking them. For example something a Java program like SQL Developer (and/or Toad). If those values are not overrulled by the program by for example using his own variables from a config file or else, those sessings from the "system" / control panel item will be used. If it is the wrong mix, you will encounter strange issues.
Setting ORACLE_HOME and ORACLE_BASE will be used by a lot of derived other settings for example the default place SQL*Net drivers and tnsnames aliases etc will be checked. For example setting the ORACLE_HOME to
C:\> set ORACLE_HOME=C:\oracle\product\10.2.0\db_1will result in that the tnsnames aliases from
C:\> set ORACLE_HOME=C:\oracle\product\10.2.0\db_1\NETWORK\adminwill be used and NOT the ones maybe needed from
C:\oracle\product\11.2.0\dbhome_1\NETWORK\adminYou can overrule this behavior by setting the TNS_ADMIN variable. By default, most explicit form for example on linux and Unix, the following rule will be used by Oracle
1) .tnsnames.ora in the home directory of the user
2) standard default: $ORACLE_HOME/network/admin
3) behavior can be overruled via setting $TNS_ADMINThe fact that you are able via Toad to execute it correctly proves you that it can be done. But Toad uses in your session "SQL*Net" or JDBC or ODBC or ADO or ? via its own configuration environment settings that are being set on which values...?
Both Oracle and Toad use the OSI model (http://en.wikipedia.org/wiki/OSI_model), both have to follow the same rules. There hasn't been changed that much over the years, character set conversions are done in the "two task common" layer of the data transport on either side (client/server) when data travels between a client and server. And don't forget a database can be also be a client when for instance database links are being used. One of the reasons to read old manuals because there the basics are still perfectly explained: http://download.oracle.com/docs/cd/A57673_01/DOC/net/doc/NWUS233/ch2.htm#twotask (Oracle 7.3.4 Networking Manual).
This long long story is just to show you that you have more control if you set variables explicitly in a "cmd" window (and or in a linux/unix shell (as long as the session isn't "forked")) BUT you will have to be precise. Check the environment a set those environment variables that control / that are being used by "sqlldr" (and that are probably more then you realised, for example that SQL_PATH variable is the default directory where SQL*Plus is looking and saving its "SQL" and spool "LIS" files).

Schema evolution success! But new node is empty in XMLTYPE column?

Hi everyone!
Quick question. I am working through the XML Schema evolution process and was able to use inplaceevolve successfully. I can see the new node added to my schema under user_xml_schemas. However, when I try to upload an XML document with that new node, it shows up in the stored XML as empty?
Here are some more details...
I added the assistant nickname element
<element name="spousePartner" nillable="true" minOccurs="0" type="xsd:string" />
<element name="title" nillable="true" minOccurs="0" type="xsd:string" />
*<element name="assistantNickName" nillable="true" minOccurs="0" type="xsd:string" />*
and I see it was added in my registered schema.
I then add the node to my test XML and in my program's console I see the node being parsed...
physicalStreet>10 Green St</physicalStreet>
<salutation>Ms.</salutation>
<title>CEO</title>
*<assistantNickName>Big Bird</assistantNickName>*
</contact>
However, when I look at the stored XML in my XMLTYPE column, I see an empty node...
<physicalStreet>10 Green St</physicalStreet>
<salutation>Ms.</salutation>
<title>CEO</title>
*<assistantNickName/>*
</contact>
What am I missing?
Any help is greatly appreciated - thank you much!

Inserting large xml data into xmltype

Hi all,
In my project I need to insert very large XML data into xmltype column.
My table:
CREATE TABLE TransDetailstblCLOB ( id number, data_xml XMLType) XmlType data_xml STORE AS CLOB;
I am using JDBC approach to insert values. It works fine for data less than 4000 bytes when using preparedStatement.setString(1, xmlData). As I have to insert large Xml data >4000 bytes I am now using preparedStatement.setClob() methods.
My code works fine for table which has column declared as CLOB expicitly. But for TransDetailstblCLOB where the column is declared as XMLTYPE and storage option as CLOB I am getting the error : "ORA-01461: can bind a LONG value only for insert into a LONG column".
This error means that there is a mismatch between my setClob() and column. which means am I not storing in CLOB column.
I read in Oracle site that
When you create an XMLType column without any XML schema specification, a hidden CLOB column is automatically created to store the XML data. The XMLType column itself becomes a virtual column over this hidden CLOB column. It is not possible to directly access the CLOB column; however, you can set the storage characteristics for the column using the XMLType storage clause."
I dont understand its stated here that it is a hidden CLOB column then why not I use setClob()? It worked fine for pure CLOB column (another table) then Why is it giving such error for XMLTYPE table?
I am struck up with this since 3 days. Can anyone help me please?
My code snippet:
query = "INSERT INTO po_xml_tab VALUES (?,XMLType(?)) ";
          //query = "INSERT INTO test VALUES (?,?) ";
     // Get the statement Object
     pstmt =(OraclePreparedStatement) conn.prepareStatement(query);
     // pstmt = conn.prepareStatement(query);
     //xmlData="test";
//      If the temporary CLOB has not yet been created, create new
     temporaryClob = oracle.sql.CLOB.createTemporary(conn, true, CLOB.DURATION_SESSION);
     // Open the temporary CLOB in readwrite mode to enable writing
     temporaryClob.open(CLOB.MODE_READWRITE);
     log.debug("tempClob opened"+"size bef writing data"+"length "+temporaryClob.getLength()+
               "buffer size "+temporaryClob.getBufferSize()+"chunk size "+temporaryClob.getChunkSize());
     OutputStream out = temporaryClob.getAsciiOutputStream();
     InputStream in = new StringBufferInputStream(xmlData);
int length = -1;
int wrote = 0;
int chunkSize = temporaryClob.getChunkSize();
chunkSize=xmlData.length();
byte[] buf = new byte[chunkSize];
while ((length = in.read(buf)) != -1) {
out.write(buf, 0, length);
wrote += length;
temporaryClob.setBytes(buf);
log.debug("Wrote lenght"+wrote);
     // Bind this CLOB with the prepared Statement
     pstmt.setInt(1,100);
     pstmt.setStringForClob(2, xmlData);
     int i =pstmt.executeUpdate();
     if (i == 1) {
     log.debug("Record Successfully inserted!");
     }

try this, in adodb works:
declare poXML CLOB;
BEGIN
poXML := '<OIDS><OID>large text</OID></OIDS>';
UPDATE a_po_xml_tab set podoc=XMLType(poXML) WHERE poid = 102;
END;

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"?>
<xs:schema
               xmlns:xs="http://www.w3.org/2001/XMLSchema"

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"

SYS_NTtu05ilrRQqmuEN4k+07VDA==     Customer402_COLL     OutboundParty403_TAB     "XMLDATA"."Customer"
SYS_NTK6fhWq5uTJ+vKcgBpNm1Fg==     InvOrder386_COLL     SYS_NTIIzv7bkXQSSS43igtfi5eg==     InvOrder
SYS_NTIIzv7bkXQSSS43igtfi5eg==     Customer387_COLL     SYS_NTaK/5zar5S0WitSsgu6OKPQ==     Customer

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

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.
