Toplink, XML and CLOB/NCLOB

Hi
New problem with Toplink;)
We want to insert an XML into a NCLOB field in the database. The NCLOB field is mapped to a String field in my object model. Toplink generates and executes the SQL but the data is not inserted. When I cut and paste the SQL into TOAD it generates an "invalid character" message on the insert. Toplink gives no error message.
We use toplink in a J2EE web-app and are therefor useing a thin jdbc driver. The toplink version is 9.0.4.
Has anyone done anything like this?
Thanks!

Hi Bent,
Could you please post the log with TopLink-generated SQL.
Also I would try to determine whether it's "N" or "CLOB" that causes the problem.
If you change NCLOB to NVARCHAR2 is the problem still there?
If you change NCLOB to CLOB is the problem still there?
This article describing LOB mapping in TopLink may be helpful, too:

XML and CLOBS

I'm using the XSU's PL/SQL API's to extract and insert data into the database. If I extract rows from tables that have clobs, and try to insert into tables that have clobs in the current database it works. If I extract the same data and try to insert across a database link to a table with clobs, it fails.
Is there a way that I can use the XSU to work with clobs?
declare
clob2 clob;
amount integer;
begin
select xmlstring into clob2
from xml_datamove
where table_name = 'MYTABLE';
amount := xmlgen.insertxml
('pprosys.MYTABLE2@dev1',clob2);
end;
declare

The first idea that comes to mind is to use Oracle Advanced
Queues and their Queue Propagation. Queues can be setup
to queue messages with any Oracle8 object type, or up-to-4K
"raw" messages.
If you create an Object type "T" with one CLOB attribute,
you can setup queues on both machines and enqueue messages
to be "moved" on one database and dequeue them on the other.
There may be other solutions, but this is the first that
pops to mind.
Browsing the LOB docs on Technet I found:
Invalid operations.
For example, the following operations are invalid:
SELECT lobcol from table1@remote_site;
INSERT INTO lobtable select type1.lobattr from table1@remote_site;
SELECT dbms_lob.getlength(lobcol) from table1@remote_site;
Valid operations.
Valid operations on LOB columns in remote tables include:
CREATE TABLE t as select * from table1@remote_site;
INSERT INTO t select * from table1@remote_site;
UPDATE t set lobcol = (select lobcol from table1@remote_site);
INSERT INTO table1@remote...
UPDATE table1@remote...
So maybe you can change to using one of the valid operation
styles above to accomplish what you want to do...

Storing and searching XML in CLOBs

Speaking to an oracle employee at the Oracle booth at JavaOne
recently. They suggested I store XML in CLOBs
and use the DOM or SAX to reparse the XML later as needed.
I agreed that this was the best solution for my problem
(which was how to manage many different XML documents using many
different DTDs in a document management system)
The big problem was searching this document repository
to locate relevant information.
This is where Intermedia seemed ideal (still does).
It would be nice to see an example of setting this up using
Intermedia in Oracle 8i, demonstrating how to define the
XML_SECTION_GROUP and where to use a ZONE as opposed to a FIELD
etc.
Anybody care to take a shot at this ????
For example:
How would I define Intermedia parameters
so that I would be able to search my CLOB
column for records that had the <keyword>
"aorta" and "damage" in the <caption>
using the following
XML (DTD implied)
<image filename="OurImageName.gif">
<fname>WellKnownFileName.gif</fname>
<keyword>echocardiogram</keyword>
<keyword>aorta</keyword>
<caption>This is an image of the vessel damage</caption>
</image>
Thanks

The example he gave involves exactly that -- searching for
text within XML elements. interMedia can do this.
: It also does not do attributes.
Upcoming 8.1.6 version allows searching within
attribute text. That's something like:
dog within book@author
We're working on attribute value sensitive search,
more like:
dog within book[@author = "Eric"]

end;
create index myidx on mytab(mytxtcolumn)
indextype is ctxsys.context
parameters ('section group mygrp');
select * from mytab
where contains(mytxtcolumn, 'aorta within keyword')>0;
options:
* use XML section group instead of basic section group
if your tags have attributes or you need case-sensitive
tag detection
* use zone sections instead of field sections if your
sections overlap, or if you need to distinguish
between instances. For instance, keywords. If keywords
is a field section, then
(aorta and echocardiogram) within keywords
finds the document. if it is a zone section, then it
doesn't, because they are not in the SAME instance of
keywords.

Toplink xml binding session.xml and servlet

I made a project with toplink-jaxb mapping
with simple pojo object it works fine.
I made another project with servlet
and the same session.xml and java classes
but when my process start it throw an exception :
jaxbexception : Provider oracle.toplink.ox.jaxb.JAXBContextFactory could not be instantiated:
It is like the process could not read the session.xml files, but this file and two xml file for the mapping are in the classpath (in WEB-INF/classes).
Have i to put these files in another place ?
Thanks.

Hi,
thank you for your response but
here is the code :
javax.xml.bind.JAXBContext jaxbContext = javax.xml.bind.JAXBContext.newInstance(
"fr.cnav.cramse.pgpe.contactsnationaux"),this.getClass().getClassLoader());
but i still got the same exception :
05/03/01 08:24:33 exceptionProvider oracle.toplink.ox.jaxb.JAXBContextFactory could not be instantiated: java.lang.NoSuchMethodError: oracle.toplink.publicinterface.Session oracle.toplink.tools.sessionmanagement.SessionManager.getSession(oracle.toplink.tools.sessionconfiguration.XMLSessionConfigLoader, java.lang.String, java.lang.ClassLoader, boolean, boolean)
I have also a stange message in the log window in jdev :

XML in clob columns and OWB

I’m building some ETL process to extract data from XML in CLOB columns. I know that there are solutions to use functions as extractvalue() of WB_XML_LOAD(), but I want to know if there is any other way to deal with XML. The reason for that is because my XML files have multiple namespaces and nodes, and I need something more complex to deal with that, since I already tried those two first solutions.
My first solution was to create a PL/SQL that parses the XML and looks for tags and elements. It populates a relational table, and I might use OWB to extract the data from this table. But I’m dealing with a large table and it takes a while for processing, plus my code is hude!
My question is: Does someone have any experience with complex XML in Clob columns? If so, what was your solution for that?
Thanks a lot!

CLOB is a fully-updateable, character large object that is stored inside the database. It can be text-indexed using interMedia for document searching.
BFILE is a readonly pointer to a file on the external file system whose content is not physically stored in the database. It can also be text-indexed for document searching, but it can't be updated.

BLOB and CLOB data in BI Publisher

Hello,
I have an XML file with blob and clob data in it. I am using BI desktop publisher to load the xml file and create the rtf template. I am getting the following error:
ConfFile: C:\Program Files\Oracle\BI Publisher\BI Publisher Desktop\Template Builder for Word\config\xdoconfig.xml
Font Dir: C:\Program Files\Oracle\BI Publisher\BI Publisher Desktop\Template Builder for Word\fonts
Run XDO Start
Template: C:\work\employee.rtf
RTFProcessor setLocale: en-us
FOProcessor setData: C:\work\employee.xml
FOProcessor setLocale: en-us
Do i need to install anything or am i missing any configuration to read the blob and clob? Please advise
thanks

Check this out, hopefully it'll help you

From XML in CLOB to relational table doubt

versions 11.2.0.2.0 / 10.2.0.4.0
It's a long time, no see since my last dealing with xml and no luck to have an attribute value returned into the relational table.
It's *<IntrBkSttlmAmt Ccy="???">999999</IntrBkSttlmAmt>*
For the rest the below works in both versions but used on an xml having a 10000 <CdtTrfTxInf> on 11g it took 9 seconds and was killed because no answer was produced after 30 minutes on 10g. A colleague using java loaded the relational table in 34 seconds on 10g and produced the relational table on 11g in just 5 seconds.
The 10g version is surviving with no xmldb installed and there are rumors our thinking heads didn't succeed to deactivate it on 11g yet.
Any suggestion concerning alternate ways to produce a relational table from an xmltype located in a clob column of a relational table are welcome
(looking at CLOB in XML to Normal table Best approach? I thought too many xmltable would have to be used)

Hi,
It's a long time, no see since my last dealing with xml and no luck to have an attribute value returned into the relational table.When you use this :
<Ccy>{$r/IntrBkSttlmAmt/@Ccy}</Ccy>That doesn't set the value of the Ccy element with the attribute value, but actually add the attribute Ccy to the element Ccy, which results in
<Ccy Ccy="???"></Ccy>Knowing that, you have three options :
1) Leaving the XQuery as it is and using this instead in the COLUMNS clause :
                         ccy             varchar2(50)    path '/rw/Ccy/@Ccy',2) Modifying the XQuery to get the atomic value out of the attribute (using the fn:data function) :
                          <Ccy>{fn:data($r/IntrBkSttlmAmt/@Ccy)}</Ccy>3) Simplifying the whole thing, something like :
select v.instrid, v.endtoendid, v.txid, v.cd, v.ccy,
       replace(v.intrbksttlmamt,'.',',') as intrbksttlmamt, v.chrgbr, v.bic1, v.nm1, v.adrline11, v.adrline12, v.ctry1, v.iban1,

XML in CLOB or BFILE

Could somebody tell me the different between save XML in CLOB and BFILE, addition to generic different between CLOB and BFILE, is there a performance issue?
Thanks

CLOB is a fully-updateable, character large object that is stored inside the database. It can be text-indexed using interMedia for document searching.
BFILE is a readonly pointer to a file on the external file system whose content is not physically stored in the database. It can also be text-indexed for document searching, but it can't be updated.

Xsl:include xsl:import and clob

I can use xslprocessor.processXSL to perform transformation where the XML and XSL are in CLOBs.
However, is it possible to perform transformation if the XML and XSLs are in CLOBs and the XSL have xsl:include and xsl:import?
Thanks and Regards,
Andy

It will be supported in later release.

Import xml and query

Hi,
Thanks in advance for reading this.
I am new to this XML and import into database.
I have the xml file, i need to import this into database and search on the database.
I have around 2.2 million records in the database.
Please explain me what is best method of storing in database, like store the file in clob column and search on the clob column.How the search is going to be on 2.2 million records.
Please send me any if any sample code you have to [email protected]

The answer on this question also depends on the version of the database you are using.
With 9i/10g i would probably use structured storage of XML (based on the XMLschema).
But the answer also depends on another question: does the XML document contains "2.2 million records" or will you be storing 2.2 million XML documents?

Retrieve the large volume XML in CLOB

If I store the larage volume XML documents
in the database CLOB field,
How can I retreive the corresponding XML file
efficently?

Migrating V9 to V10: Update XML Fragment CLOB does not work anymore

I have an XML Schema that contains an element, named Operazione, mapped to a CLOB.
I just migrate to Oracle 10.1.0.2.0 from version 9.2.0.2.0 and the code I developed does not work anymore.
To get a CLOB on v 9.2.0.2.0 I issued the following statement:
select extractValue(value(p),'/operazione.log/Operazione') from XMT_OPERAZIONE_LOG p
where existsNode(value(p),'/operazione.log/Journal[NumeroElettronico=1234567890]') = 1
To make it working on V10 I have to change it as follow:
select extract(value(p),'/operazione.log/Operazione').getClobVal() from XMT_OPERAZIONE_LOG p
where existsNode(value(p),'/operazione.log/Journal[NumeroElettronico=1234567890]') = 1
So using extract intead of extractValue and adding getClobVal() I was able to read the CLOB.
The problem that I was not able to solve is related to CLOB update. In V9 just adding the âfor updateâ clause I was able to change the CLOB value on DB.
In V10 if I run the V9 statement I get the error:
ORA-03113: end-of-file on communication channel
If I use the statement modified for V10, adding the âfor updateâ clause, I get the CLOB and I can change the CLOB value but nothing goes on the DB. Probably I am working on a copy of the DB CLOB.
If I remove the getClobVal() I get an OPAQUE type that I can use on a XMLType but, still, nothing is stored on DB.
Any suggestion ?
I tried with both OCI and Thin Client

Can anybody help me ?
Is it better to use different strategies ( eg. Stored Procedure, DBMS_XMLSTORE etc, etc. ) ?
Any experience updatating XML Fragment CLOB on Oracle V10 ?

XML to CLOB & UTF-8 Queries

I need to create xml files from the available data in the DB tables. I am planning to use SQL/XML functions(xmlroot,xmlelement etc) to construct a well-formed
xml and stored in CLOB data objects. I will use SPOOL command to get the clob (OUT parameter) in my client server (UNIX).
Does any temporary CLOB objects will be created and not cleared by Oracle engine in the table space? If yes,how can i use dbms_lob.freetemporary(clobvar);
to clear the CLOB object after the successful creation and spooling of the xml is done.
I need to have utf-8 character set and achieve url escaped chracters as well, please let me know if these can be done without using UTL_HTTP or any other UTL packages.

           , xmlelement("hiredate", hiredate)
       ),version '1.0" encoding="UTF-8').getClobVal()
       into xml
    from EMP_DETAILS;
   vxml := xml;
END test_proc;
END;Does this pl/sql code block create any temp CLOB's (or) do i need clear/free xml CLOB variable used here after completion or in case of exception?

XML Import CLOB column size limit

I have a table with a CLOB column and some of the rows have up to 7000 characters in the column. I exported the table to XML and the XML file contains all the data. When I try to import the file into another APEX instance I get the error:
XML Load error.
After some experimentation, I found that If I manually edit the XML to reduce the size of the text to under 4000 characters (3700 in my test), it imports fine.
Is there a way around this limitation? The database I'm migrating has LOTS of CLOB columns (converted from MS Access "memo" fields).

jlange,
Having converted a bunch of MS Access applications myself, I would encourage you to look at the Oracle Migration Workbench (OMWB): http://www.oracle.com/technology/tech/migration/index.html
This free tool can be downloaded from OTN, and provides a more streamlined approach to moving the data from MS Access to Oracle, including support for Memos to CLOBs.
Once you're data has been moved over, you can then use ApEx to re-create the UI.
Thanks,

How to parse/extract XML from clob field using ODI

Hi,
I am very new to ODI. I have an oracle table which has clob field. This clob field contains xml. I would like to parse this xml and convert it to oracle table. Means I would like to make all the tags of xml as oracle table columns.
I have created a PL/SQL procedure and used XMLTABLE function and I have achieved my goal. The same this I am trying to do with ODI. Since I am new to ODI so any help is appreciated.
Thanks

In 9.2, you are limited into your options. Have a look into, among others, updateXML. Updating tp 10gR2 will give you more options to succeed.
