Documents in Clob

Can I store Word Perfect, Word, WordPad, etc text documents in a Clob column on a 9i database? I want to use Clob so the document can be searched is there another way to do this?
Thanks

XML document in CLOB with reference to external DTD

If you place the xml document in clob using dbms_lob and the document has reference to external (system) DTD then it gives an error 'Error opening external DTD'. Whats the work around. See example below...
declare
xmlstring CLOB;
xmlstring1 CLOB;
os_file BFILE := bfilename('BFILE_DIR','family.xml');
> > > rowsp INTEGER; > > > errnum NUMBER; > > > errmsg VARCHAR2(2000);

Can be one of two problems.
One
Your database user does not have
privileges to open a socket inside
the database. This will prevent
the XML parser running inside the DB
from retrieving the DTD which it must
do to properly parse the document.
Two
you are sitting behind a corporate
firewall and need to properly set
the Proxy Server host and port to
properly retrieve the DTD.
From looking at your code it would appear
that your job can more easily be done by
using the OracleXML putXML command line
utility outside the database.
You can specify the -D options to your
JavaVM to set the System properties for
the proxy server if need be like this:
java -DproxySet=true -DproxyHost=yourproxyserver OracleXML putXML

Load xml document from CLOB

I'm try to load xml document from CLOB in following way:
--- procedure loadXML.sql -----
CREATE OR REPLACE PROCEDURE loadXML
IS
CONTENT CLOB := ' ';
SOURCE bfile := BFILENAME('XMLFILES', 'N_95_A.xml');
begin
DBMS_LOB.OPEN(SOURCE, DBMS_LOB.LOB_READONLY);
DBMS_LOB.loadFromFile(CONTENT, SOURCE, DBMS_LOB.getLength(SOURCE));
DBMS_LOB.fileClose(SOURCE);
insert into OFERTY (OFDOCUMENT)
values (sys.XMLtype.createXML(CONTENT));
commit;
end;
and I get
SQL> @e:\myxml\loadXML
declare
ERROR at line 1:
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00210: expected '<' instead of '<'

What is wrong?

Have you tried simply outputting iusing the htp.p function? for example:
/* ... inside a PL/SQL region */
declare
   lclb_output clob;
begin
   select doc_xml into lclb_output from mf_xml_docs where doc_id = :P1_DOC_ID;
   htp.p(lclb_output); -- you may have to split this into chunks and loop through, depending on how big the clob is
end;

Display XML Document from CLOB Column on page

Hi,
I have been reading all the CLOB postings that I can find, but I still cannot get my page to do what I want.
I have a very simjple table:
MF_XML_DOCS (DOC_ID NUMBER, DOC_XML CLOB)
I can populate this table OK but I am having problems getting the cotent back out. I want a simple page that takes an ID Number and displays the XML Document for that ID (select doc_xml from mf_xml_docs where doc_id = :P1_DOC_ID). Everything I try either truncates the text (or errors) at 4000 or 32767 characters or reads the XML tags as tags and does not display them. I want a simple display of the XML Document (and I don't mind if it is in an 'updateable' field or not):
<Parent>
   <name>Dad</name>
   <Children>
      <Child>
         <name>Number 1 Son</name>
     </Child>
      <Child>
         <name>Number 2 Son</name>
     </Child>
   </children>
</Parent>But when I do something that works for large (32767+) documents all I see is 'Dad Number 1 Son Number 2 Son'.
Help!!
many thanks,
Martin

Something is wrong about passing xml document to clob

Dear All,
I have a procedure that uses XMLELEMENT to create an XML source. When I try to pass the XML source to the outgoing parameter of the procedure I receive an error saying
"ORA-19011: Character string buffer too small"
When I checked the length of the source it was just 5000 characters long. How is it possible that I can't give this to a clob?
Thank you,
Franky

I'm going to answer it for myself.
Use getclobval() function any you will succeed.

Intermedia text search in XML document stored as CLOB

Suppose i store an XML document as clob
and i index it based on the tags ie
if i have the followind table
create table biodata (
resume_id number primary key,
content clob default empty_clob(),
applicant_id number references
applicants(id));
and i stores various resumes in the clob (content column ) as xml document ie
<experience_in_months> 22 </experience_in_months>
Now if i want all the resume_id that that have experiences_in_months >= 10
what would be the query that would fetch me this result?

We are storing data in XML format in an Oracle database (via CLOB). I can retrieve search results using the 'within' phrase, but am finding it hard to order them. Is there a utility or command I can use?<HR></BLOCKQUOTE>
Maybe you should write a stored procedure (function )
that extracts the section from your clob
that should be sorted. Then use this function
in the ORDER clause of your select statement.

Hello,
many thanks for the reply. Your examples are very usefull for me.
To answer your questions.
An XML structure:
/etd
    /header - repeat in each row in output
    /account_group/account
        /invoice
            /da - repeat for each details under "selected "invoice
            /detaildc/dc - the lowest level
            /detaildn/dn - the lowest level
            /dt - repeat for each details under "selected "invoice
    /footer - repeat in each row in outputI would like to to have a 1 row for each "record" in /detaildc section and include related nodes at higher levels.
Please see below XML file, which is simplified file of example in first post, but includes a complete xml structure which needs to be queried in db.

Mapping XML documents in Oracle

I am a newbie in Oracle.
I would like to know how to store entire XML documents in CLOBS.
Since yesterday I hear about XSQL, and I was wondering if nobody had some sample code to realize this mapping.
Thanks in advance for your help

Oracle Issue around handling CLOB within Workflow Transaction

Hi,
- In Workflow Notification Message I am using an CLOB Document for building the
message Body
- This CLOB value is going to be SELECTed and initialized from a TABLE
(having CLOB column) during the document related procedure execution
NOTE: In order to select from a CLOB we need to issue FOR UPDATE
to have read consistency
(otherwise it will give LOB not locked for update error during notification display)
Here the issue I am facing is :
The same notification is going to be sent to Multiple users (thru Notification
to a Apps.Responsibility i.e. WF Role)
When USER1 opens the notification, the CLOB Table row gets a lock
(due to FOR UPDATE) and is not released until ROLLBACK/COMMIT
which will not happen as it is a workflow (if I put this Select FOR UPDATE
in a AUTONOMOUS transaction then it gives error as LOCATOR id cannot
spawn between transactions during the notification display)
When USER2/USER3 opens the same notification which he received being a member
of the Responsibility , the notificaiton screen gets hanged as it again
tries to issue SELECT FOR UPDATE and sees USER1 holds the lock.
My Requirement is:
When first time anyone user opens the notification, it will not find a record in table
so it builds the notification and stores the CLOB record into the table.
Next time onwards all the users should get the stored record from the table
(Read CLOB value from Table and show in the Notification Message Body)
Please help me in resolving the SELECT FOR UPDATE of a CLOB within Workflow
when multiple users need to issue without the need of a COMMIT/ROLLBACK
NOTE: Even I am only Reading the CLOB value from a Table, without
having any need of updating it, still I need to Issue FOR UPDATE
as per Oracle CLOB constraint.
thanks,
Shashi

Hi,
I didn't do the select directly into document when I did it in my test. Here's the two different methods that I used in my database to test the problem:
create or replace procedure msclobtest
                   (document_id   IN     VARCHAR2
                   ,display_type IN     VARCHAR2
                   ,document      OUT    CLOB
                   ,document_type OUT    VARCHAR2
                   ) as
cursor c1 is select theclob from ms3 where clob_id = 4;
v_clob clob;
begin
debug('started clob');
open c1;
fetch c1 into v_clob;
close c1;
document := v_clob;
document_type := 'text/html';
debug('clob ended');
end;
create or replace procedure msclobtest
                   (document_id   IN     VARCHAR2
                   ,display_type IN     VARCHAR2
                   ,document      OUT    CLOB
                   ,document_type OUT    VARCHAR2
                   ) as
cursor c1 is select theclob from ms3 where clob_id = 4;
v_clob clob;
begin
open c1;
fetch c1 into v_clob;
close c1;
dbms_lob.createtemporary(document,FALSE);
dbms_lob.copy(document,v_clob,dbms_lob.getlength(v_clob));
document_type := 'text/html';
end;If it's not the code, then it might be something in the Workflow itself.
Are the values of the document attribute being set correctly in the Workflow? Are you sending to a role? Have you checked the "Expand Roles" tick box? Have you checked the "Attach Content" tick box?

HELP:Problem in creating a temporary CLOB using JDBC connection pooling

Hi All,
i am inserting a large xml document in an xml type column by creating a temporary clob of this document
tempClob = CLOB.createTemporary(conn, true, CLOB.DURATION_SESSION);
I am not having any success getting the following statement working using a JDBC connection pool rather than a hard coded URL connection
it works with:
"jdbc:oracle:thin:@server:port:dbname" connection
Does NOT work with:
datasource.getConnection()
Does any one know how to successfully get this to work?
urgently plz........

Hi Dharmi
Here is a quote of Dafna's post in [another thread in this forum|Re: Copy VC controls]
CE7.1.1 will be released at September 2008 for ramp-up customers.
There are many improvements and new capabilities in the new release of Visual Composer for CE7.1.1. Among the new features you can find:
The missing features from Visual Composer 7.0 (Html view, portal Eventing support (EPCM), JDBC, Undo/Redo, and more..)
Many layout & modeling improvements
Additional ALV table functionality - export to Excel, switch to chart, configure ALV behavior at design time
Integration of Visual Composer in Eclipse - additional entry point to the Visual Composer models from the NWDS. This integration provides the option to add a WD component (in case of missing functionality in Visual Composer), as a black box component to the Visual Composer model. Right-clicking the component will open the Web Dynpro perspective for creating/modifying the component.

AQ - XSD Schema Questions

What I am looking to do is use BPEL for messaging (and manipulation of said messages) in the backend for data synchronization to disparate sources.
Currently, we are investigating the following:
Oracle 9i DB with a stored procedure that accepts a number of parameters (or XML Document in CLOB format), processes the document (updates, typically), and before returning, writing the output XML document to an AQ setup on that DB instance.
BPM (installed on an OAS 10g server instance) would be utilizing the AQ adapter to dequeue this message for processing through the orchestration.
This is where our difficulty begins. The message the SP generates is based on an enterprise schema (EBOD - currently), which is a relatively robust XSD. Currently, we're looking how to get the AQ adapter to pick up this message (should it be a clob?) off the queue and essentially cast it into our schema that we've imported into the BPM. We haven't had much success doing this so far. Implementing a ADT that is "typed" in the 9i DB by retyping the entire schema is unacceptable, for obvious reasons.
I think what we're looking to do is take this clob and essentially "cast" it into a message format defined by our schema. Maybe there is a better way to tackle this problem, by using something besides a CLOB (XMLType isn't supported yet, but even then... would that solve our problem?), but I am unsure. We need the message in a manipulatable form in order to call additional web services (that have differing interfaces) by extracting certain elements and passing those. Additionally, we may wish to do some business logic, routing, etc.
I can clarify what I'm looking to do, but basically 9i DB Stored Proc writes an XML doc to an AQ. BPEL is monitoring said AQ, picks up the CLOB (that type for now) and casts the message to it's schema that we've loaded (no transformation necessary, the schema is for the specific XML doc - ie. the doc validates to that schema) and we basically go forward and process the rest of the orchestration based on this message.
Can anyone help me with this approach? Any other suggestions?

Hi Todd,
The AQ Adapter allows the user to pick a CLOB field within an ADT as the payload and supply a schema for its definition.(pick "Field within Object" for the Business Payload in the AQ Adapter wizard)
Your 9i DB Store Proc would write to the queue which is defined based on the ADT, with xml payload stored in the CLOB field. The BPEL process would be able to pick up this payload thru the AQ Adapter.
There is a sample illustrating this scenario in the installation.
integration\orabpel\samples\tutorials\124.AQAdapter\ADT_with_CLOB_Payload
Note the sample also uses payload header which is defined by the ADT structure to access fields other than the payload field. The use of headers is optional.
Let me know if this is what you're looking for.

About this XML database

Today I have found these definitions:
1.Native XML Database (NXD):
a) Defines a (logical) model for an XML document -- as opposed to the data in that document -- and stores and retrieves documents according to that model. At a minimum, the model must include elements, attributes, PCDATA, and document order. Examples of such models are the XPath data model, the XML Infoset, and the models implied by the DOM and the events in SAX 1.0.
b) Has an XML document as its fundamental unit of (logical) storage, just as a relational database has a row in a table as its fundamental unit of (logical) storage.
c) Is not required to have any particular underlying physical storage model. For example, it can be built on a relational, hierarchical, or object-oriented database, or use a proprietary storage format such as indexed, compressed files.
2.XML Enabled Database (XEDB) - A database that has an added XML mapping layer provided either by the database vendor or a third party. This mapping layer manages the storage and retrieval of XML data. Data that is mapped into the database is mapped into application specific formats and the original XML meta-data and structure may be lost. Data retrieved as XML is NOT guaranteed to have originated in XML form. Data manipulation may occur via either XML specific technologies(e.g. XPath, XSL-T, DOM or SAX) or other database technologies(e.g. SQL). The fundamental unit of storage in an XEDB is implementation dependent. The XML solutions from Oracle and Microsoft as well as many third party tools fall into this category.
3.Hybrid XML Database (HXD) - A database that can be treated as either a Native XML Database or as an XML Enabled Database depending on the requirements of the application. An example of this would be Ozone.
Which of them would you put XML DB in?

If we consider the duality of the XMLType (store XML documents in CLOB's and structured storage with XML Schemas), could we say that it is an hybrid XML database?
Native->CLOB's
Enabled->structured storage
I suppose this cuestion is a bit subjective, but I would like to know your opinions.
Thanks in advance!

XML Parser for PL/SQL - charset

Hi,
I'm using XML Parser for PL/SQL and have some trouble with encoding of results xmldom.writeToBuffer and xmldom.writeToCLOB procedures.
Some tags in my DOM documents contain text values in RUSSIAN (server nls_charset is CL8ISO8859P5). When I write document in varchar2 variable, buffer content is in UTF8 encoding ( convert UTF8->CL8ISO8859P5 -OK).
xmldom.setCharset(doc, 'ISO-8859-5') just after xmldom.newDOMDocument has no effect.
xmldom.setCharset(doc, 'CL8ISO8859P5') has no effect also.
Explicit charset direction in third parameter of
xmldom.writeToBuffer and xmldom.writeToCLOB procedure has no effect.
When I write document in CLOB, and then read part of CLOB in varchar2 buffer - result contain '?' in place of all russian text characters.
What's a problem?
How can I force XML Parser write XML in server charset?
Platform:
Oracle8i Enterprise Edition Release 8.1.6.1.0
JServer Release 8.1.6.1.0
Oracle XML Parser for PL/SQL v 1.0.2

I have the same problem. But in my case I am allowed only to use XML Parser for PL/SQL.
Characterset 'WE8ISO8859P1' is used. And the language is latvian.
After parsing a XML document and printing its contents, all latvian characters are replaced by "f".
xmldom.setcharset(doc,'WE8ISO8859P1') has no effect.

PL/SQL to generate XML compliant with an XSD

Please excuse me if this has been asked elsewhere. I'm trying on Oracle 9.2 to output XML that will comply with a predefined schema. I've started out by creating various object types and an object view that matches the xml schema definition, and can use dbms_xmlgen.getxml to get out an xml document (a clob) without trouble, BUT I need to post-process this with shell scripts to add on the namespace information and amend the tags to put in the (e.g.) ns3: bit to identify which is the target namespace. It seems odd that I should need to do this - is there a better way? I have trawled all over rthe place but cannot find any mention of this requirement. Thanks for any help you might give me, I'm new to xml.

Okay forget that, here's a quote from Oracle:
"I'm the PM for XML DB, and our preferred direction for generating XML from data stored in relational tables is the industry standard SQL/XML operators. DBMS_XMLGEN will continue to be supported but most of our development efforts in terms of performance / feature improvements willl be targetted at the SQL/XML operators (XMLELEMENT(), XMLATTRIBUTES(), XMLAGG(), XMLFOREST() etc). In general they have proven to be much more flexible and performant, and easier to use "
So it seems that the object-type/view route is dead in the water. Shame.
