Clob or XML

Hello,
I need to store product specifications and definitions to display on the internet. These definitions are very long and detailed. Moreover, they include imagery. I need to develop queries on these products, too.
Should I store all the descriptions as CLOB type or use standard XML file for them? When I display the page, I can get the key information from ORACLE tables, and the descriptions from XML files. Will this work fast? Or CLOB will be fast enough to display long text on the internet?
Thanks,
Gabriel

The definitions are not just couples of words or
sentences. They are at least half a page long
detailed descriptions, and there are at least 10
different variables like this. If I don't use CLOB,
how else can I store them?
Thanks,The approach is to model the information contained in the description, rather than just poke it into the database as big aptly named clob of text.

BUG : CLOB or XML.

Hi! I was playing with XML and CLOB and I think I found a bug with clobs. I would like a DEV to try this.
=========================================================================================================
First, you create the following function :
=========================================================================================================
function clob_bug return clob
as
sdo mdsys.sdo_geometry := mdsys.sdo_geometry(123, 123, null, mdsys.sdo_elem_info_array(1, 2, 3), null);
xml sys.xmltype;
text clob;
str varchar2(32000);
begin
xml := xmltype.createXML(sdo);
text := xml.getClobVal();
-- This doesnt work.
return text;
-- But this will work. (But the XML text cannot exceed 32000 chars, or so);
-- str := text;
-- return str;
end;
=========================================================================================================
Then try the following VB.NET code.
=========================================================================================================
'Fill in the datasource.
Dim connection As New Oracle.DataAccess.Client.OracleConnection("User Id=SCOTT;Password=TIGER")
Try
connection.Open()
Dim cmd As Oracle.DataAccess.Client.OracleCommand = connection.CreateCommand()
cmd.CommandText = "SELECT CLOB_BUG() FROM DUAL"
Dim o As Object = cmd.ExecuteScalar()
Catch e As Oracle.DataAccess.Client.OracleException
Console.WriteLine(e.Message)
End Try
=========================================================================================================
Then you should get the following error :
"ORA-00000: normal, successful completion"
With an internal error code of -3000 (dont know what it means, but you guys should!).

I found a much easier way to reproduce the bug. forget about the PL/SQL function.
Dim connection As New Oracle.DataAccess.Client.OracleConnection("User Id=SCOTT;Password=TIGER;")
Try
connection.Open()
Dim cmd As Oracle.DataAccess.Client.OracleCommand = connection.CreateCommand()
cmd.CommandText = "select SYS_XMLGEN(2).getclobval() from dual"
Dim o As Object = cmd.ExecuteScalar()
Catch e As Oracle.DataAccess.Client.OracleException
Console.WriteLine(e.Message)
End Try

Error updating a CLOB XML fragment

Hi,
I have an xml schema that contains an element of type xs:anyType that has been mapped to Oracle as CLOB.
Now I have the needs to update this value but I was not able to do it.
The code that does the update is the following:
public void updateXML(String sqlCmd, String XMLString) throws Exception
DataSource ds = null;
Connection conn = null;
OraclePreparedStatement stmt = null;
oracle.sql.CLOB tempCLOB = null;
Writer tempCLOBWriter= null;
try
//Get Data Source
ds = (DataSource) new InitialContext().lookup(xmlDS);
// Get Connection
conn = ds.getConnection();
// Prepare statement with requested insert, update or delete statement
stmt = (OraclePreparedStatement) ((OracleConnection) conn).prepareStatement(sqlCmd);
// Build CLOB containing XML if required
if (XMLString != null)
tempCLOB = oracle.sql.CLOB.createTemporary
( ((WLConnection)conn).getVendorConnection(),
true,
CLOB.DURATION_SESSION);
try {
tempCLOB.open(CLOB.MODE_READWRITE);
tempCLOBWriter = tempCLOB.getCharacterOutputStream();
tempCLOBWriter.write(XMLString);
tempCLOBWriter.flush();
} finally {
if (tempCLOBWriter != null)
tempCLOBWriter.close();
//Set parameter on Prepared Statement
stmt.setCLOB(1,tempCLOB);
// Execute command
stmt.executeUpdate();
// Clean up CLOB data if required
if (XMLString != null)
tempCLOB.freeTemporary();
// Return connection to the pool
conn.close();
catch ( Exception e)
if (conn != null)
conn.close();
throw e;
IF the sqlCmd param contains:
update XML_OPERAZIONE_LOG t
set value(t) = updateXML(value(t),
'/operazione.log/Operazione',XMLTYPE(?))
where existsNode(value(t),
'/operazione.log/Journal [NumeroElettronico="99900000"]') = 1
I get the error ORA-17410 "No More Data to read from socket"
If the sqlCmd contains:
insert into XML_OPERAZIONE_LOG values( XMLType(?))
I have no problems.
Any Idea ?
Oracle 9.2.0.2.0, latest classes12.zip BEW Web Logic 8.1

Upgrade to 9.2.0.5.0 since 9.2.0.2.0 is not supported for XMLType. Also try OCI rather than thin dirver.

How do I Load a clob from an XML field in an XMLTYPE using XMLTABLE ?

I am trying to load data into a CLOB from a XML field using XMLTABLE.
I have a SUMMARY xml field with over 100 K of data (potentialy)
and I can load all the other datatype fields to columns but can not load the xml fields over 4000 characters.
example
First I create a table of XMLTYPE. I need to sqlload new files in at regular intervals.
Create table WEB_XML of XMLTYPE;
Then I create my relational table....
create table WEB_WORKING
request_id varchar(10),
ref_number varchar(20),
summary clob
The I use the .ctl file to sqlload the xml data in
LOAD DATA
INFILE *
INTO TABLE WEB_XML
append
xmltype(XMLDATA)
ext_fname filler char(90),
XMLDATA LOBFILE(ext_fname) TERMINATED BY EOF
BEGINDATA
XMLFILE1.xml
After loading the WEB_XML table using sqlldr, I try to load my relational table using XMLTable
INSERT into WEBBAR_WORKING
request_id ,
ref_number ,
summary
SELECT X.* FROM WEB_XML P2,
XMLTable ( '//Request//REQUESTVIEW'
PASSING P2.object_value
COLUMNS
"request_id" VARCHAR(10) PATH 'REQUEST_ID',
"ref_number" VARchar(20) PATH 'REF_NUMBER',
"SUMMARY" clob PATH 'SUMMARY'
) AS X;
This gives an error saying its not expecting clob
My XML looks somthing like
-<Request>
-<REQUESTVIEW>
<REQUEST_ID>3140</REQUEST_ID>
<ref_number>2003-04-02</RECEIVED_DATE>
<SUMMARY>
OVER 100 K of data
</SUMMARY>
</REQUESTVIEW>
</Request>

ok
that helped lot, im getting there however some more help please
This SQL
SELECT request_id, recieved_by, X.SUMMARY.getClobVal()
FROM WEB_XML P2,
XMLTable
'//Request//REQUESTVIEW'
PASSING P2.object_value
COLUMNS
"request_id" VARCHAR(10) PATH 'REQUEST_ID',
"received_by" VARCHAR(10) PATH 'RECEIVED_BY',
"SUMMARY" xmltype PATH 'SUMMARY'
) AS X;
SELECT request_id, recieved_by, X.SUMMARY.getClobVal()
ERROR at line 1:
ORA-00904: "RECIEVED_BY": invalid identifier
If I use the X.request_id, X.received_by ......
i get the error message
Package or function is in aan invalid state.
But this SQL was successful in getting the clob by itself but with the XML tgs around it still, how do I strip the XML tags from around this result ?
SELECT X.SUMMARY.getClobVal()
FROM WEBBAR_XML P2,
XMLTable
'//Request//REQUESTVIEW'
PASSING P2.object_value
COLUMNS
"SUMMARY" XMLTYPE PATH 'SUMMARY'
) AS X;

How to insert more than 32k xml data into oracle clob column

how to insert more than 32k xml data into oracle clob column.
xml data is coming from java front end
if we cannot use clob than what are the different options available

Are you facing any issue with my code?
String lateral size error will come when you try to insert the full xml in string format.
public static boolean writeCLOBData(String tableName, String id, String columnName, String strContents) throws DataAccessException{
boolean isUpdated = true;
Connection connection = null;
try {
connection = ConnectionManager.getConnection ();
//connection.setAutoCommit ( false );
PreparedStatement PREPARE_STATEMENT = null;
String sqlQuery = "UPDATE " + tableName + " SET " + columnName + " = ? WHERE ID =" + id;
PREPARE_STATEMENT = connection.prepareStatement ( sqlQuery );
// converting string to reader stream
Reader reader = new StringReader ( strContents );
PREPARE_STATEMENT.setClob ( 1, reader );
// return false after updating the clob data to DB
isUpdated = PREPARE_STATEMENT.execute ();
PREPARE_STATEMENT.close ();
} catch ( SQLException e ) {
e.printStackTrace ();
finally{
return isUpdated;
Try this JAVA code.

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 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.

DDL & DML
CREATE TABLE EMP_DETAILS (ENAME VARCHAR2(50),ID NUMBER(20),HIREDATE DATE);

INSERT INTO EMP_DETAILS (ENAME,ID,HIREDATE) VALUES ('JIM',3,SYSDATE-3);

       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 to Clob convertion

Hi ,
I have a table which has a XML data type column, i need to select this coulumn and return it in CLOB type.
I know that I can convert CLOB to XML format using function Sys.Xmltype.Createxml, but I want the revrese.

My Task is To Parse a XML Document to Return CLOB's

Hi folks
I am writing this mail in the hope of getting a help.Please
give me a shoulder to keep me going.
The task is to parse a XML document for a specific Tag and
read the Tag content in CLOB to return CLOB.
I know that the writetoclob will do the job as
per oracle documentation.
I am giving the code where i got stuck.
Please help me complete my rest of coding.
Thanks
Input variables are
XMLin in CLOB, -- Incoming XML Document Structure
Partype in varchar2, -- Tagname
Result out CLOB -- Return Tag value CLOB data type.
My Code : -
Declare
p xmlparser.parser;
d xmldom.DOMDocument;
e xmldom.DOMElement;
nl xmldom.DOMNodeList;
n xmldom.DOMNode;
tagvalue varchar2(255);
paramsIn Clob;
result CLOB;
BEGIN
--loading SecXML
dbms_lob.createtemporary(paramsIn,true);
dbms_lob.append(paramsIn,XMLin);
--dbms_output.put_line('ParsebyTag ='||Partype);
--defining parser
p := xmlparser.newparser;
xmlparser.parseClob(p,paramsIn);
d := xmlparser.getDocument(p);
--get tagvalue
nl := xmldom.getElementsByTagName(d,partype);
n := xmldom.item(nl,0);
IF xmldom.getlength (nl) > 0
THEN
n := xmldom.item (nl, 0);
=>=>=> => xmldom.writetoclob (n, result); <=<=<=<=<=<=====
END IF;
return; -- from a procedure
The above line marked with a arrow does not work for CLOB Variables.
Please explain with a corrected code to complete this task.
Thanks for reading my request.
Please reply to this message poster as i am frequently

First, you have 2 variables with the same name,
Second, let me show you what is that you need to do:
PROCEDURE WriteDataToClob(XMLin in CLOB, Partype in varchar2, Result out CLOB) IS
Declare
p xmlparser.parser;
d xmldom.DOMDocument;
e xmldom.DOMElement;
nl xmldom.DOMNodeList;
n xmldom.DOMNode;
tagvalue varchar2(255);
TempClob Clob;
BEGIN
--Create a temporary clob
dbms_lob.createtemporary(TempClob,true);
--loading SecXML
--defining parser
p := xmlparser.newparser;
xmlparser.parseClob(p,XMLin);
d := xmlparser.getDocument(p);
--get tagvalue
nl := xmldom.getElementsByTagName(d,partype);
n := xmldom.item(nl,0);
IF xmldom.getlength (nl) > 0 THEN
n := xmldom.item (nl, 0);
xmldom.writetoclob (n, TempClob );
END IF;
Result := TempClob;
dbms_lob.FreeTemporary(TempClob);
END;

Special characters in XML (UTF8, escapes etc)

This may seem like a simple problem, but I'm kind of a slow learner, so any help would be appreciated.
I'm generating XML output via ordinary PL/SQL procedures i.e. not using the Oracle XSQL stuff. The data is built up into a XML document, which will be parsed within the server, then passed out to a client, probably as a CLOB.
The data may contain "special" characters such as "<&>" and so on. Is there an existing function to translate these into an "XML-safe" form within the text, or do I need to trap and translate them individually?
Also, the database may contain foreign characters e.g. Thai or Chinese. Will this be handled transparently by my XML-extraction stuff - which just selects the data from the tables and writes it to a CLOB inside XML tags - or do I have to do something to make sure the XML comes out in a safe UTF format?
Thanks,
Chris

But in that it is taking ''' for ' ' instead of '$1' it is taking '$1'
how to keep ' ' in XML file instead of &apos?

You can use bcp with query out option
use your above query as the source query and use queryout option after specifying destination as your required local file path (specify extension as .xml)

Using CLOB in 8.1.7

Hi,
Well, everything here seems simple with the use of CLOB. But unfortunately, it springs up a surprise,to me atleast, when compiled.
