Export XML data from a CLOB field using sql developer

I have a table that contains a CLOB field, each record is a complete XML in itself. After running the select query i am exporting this data by right clicking on the answer set, while the export completes the data for each record gets truncated.
When i chose to save the export in loader format i get the complete records but now there are n files created for n records exported.
Is there a way i can get alll the records in a single file wirthout any truncation.
Thanks in advance!

You might try delimited format or csv, with no enclosures if desired.

Inserting and retrieving data from a al32UTF8 database USING SQL Developer

hi guys,
Before i post my questions , i think its better for me to provide you guys with my understandings first so that it easier to understand where/if i have gone wrong..
I am using Window XP and Oracle 10g
Non-unicode client - a client program that need to use the OS code page for mapping of the retrieved unicode data from the database as well as the support of displaying/inserting the characters from that code page to the database.
E.G sqlplusw.exe
Therefore, when using a non-unicode client
1) we have to set the OS code page (Control panel - regional and language setting - advance - language for non unicode program ) to the code page that contain the characters we are going to display/insert.
2) we will also have to set the NLS_LANG characterset to the character set of the code page we are going to insert so that when we do a insert (for e.g in thai ) , oracle will know, and auto conversion to UNICODE can take place. This is also true when we retrieve unicode data from the database so that conversion to the correct character set can take place.
INSERTING
THAI ---> conversion ----> UNICODE
RETRIEVING
THAI <---- conversion <---- UNICODE
I hope my basic understanding is correct up till this point.
Unicode client - a client program that supports the displaying/inserting of unicode characters without the need of setting the OS code page (Control panel - regional and language setting - advance - language for non unicode program )
E.G isqlplus http or SQL developer
However,
1) There is still a need to set the NLS_LANG so that correct conversion can take place between the client and the database.
For e.g, when retrieving if we set the NLS_LANG character set to ZHS16GBK (chinese) and the data store in unicode in database is E.G (THAI) , then the conversion would be wrong .
Since it is a unicode supported client, then the NLS_LANG character set should be set to UNICODE as well.
Here come my questions
*Important - please help if you are busy and have no other time to answer the rest of the questions
*Q1) If i were to use a unicode client, what should i set my NLS_LANG character set to ?
AMERICAN_AMERICA.UTF8 ?
*Q2) Where do i set the NLS_LANG character set information in SQL Developer, i know there is a metalink for setting NLS_LANG using isqlplus but i cant seems to google any result for SQL developer.
Q3) Is my basic understanding right until this point ? If not, please explain in a more generalised term as i am really not familiar with character sets, code page, unicode , glyphs and fonts..
Q4) If a unicode client does not need to refer to the OS code page (set in regional and language) , is there a UNICODE code page for the client to refer to , or is there any Window API available ?
Q5)
There is still a need to set the NLS_LANG so that correct conversion can take place between the client and the >>database.
For e.g, when retrieving if we set the NLS_LANG character set to ZHS16GBK (chinese) and the data store in >>unicode in database is E.G (THAI) , then the conversion would be wrong .am i right on this point for UNICODE supported client ?
Thanks for spending time to read my questions and i hope to hear advices from you guys soon.
Million thanks again for sharing.
Best Regards,
Noob but willing to learn

The requirement to always set NLS_LANG is not true for JDBC, which ignores NLS_LANG altogether. Java programs fetch text data into String variables, which use Unicode UTF-16 by design. JDBC sets character set conversion so that data is converted between UTF-16 and the database or national character set.
The requirement to set NLS_LANG is not generally true for OCI, either. The first call in an OCI problem can be OCIEnvNlsCreate(). This call has two parameters that allow the caller to define the character set to use for VARCHAR2/CHAR/LONG/CLOB/statement text and the character set to use for NVARCHAR2/NCHAR/NCLOB. Only if these character sets are specified as 0, NLS_LANG character set is used. Also, OCI programs can specify different character sets for each bind or define variable (i.e. input/output buffer). Note: OCI programs always use NLS_LANG to initialize the language and territory settings for the client program and the database session. Only the character set can be specified is OCIEnvNlsCreate().
OCIEnvNlsCreate() can specify the client character set as UTF-16 (in platform endianess). This is not possible with NLS_LANG.
Various interfaces building on OCI, such as Oracle ODBC and ODP .NET, explicitly initialize OCI with Unicode character set, and thus ignore the NLS_LANG character set as well.

Apex.ajax.clob - retrieving data from a clob field

I have an application that uses a table that stores xml data, and the field in the table that stores the data is a clob. I used Carl Backstrom's example to build what I have so far, (God's blessings on his family). Here is the script I use to store the data from an HTML Editor into the database:
function clob_set(request){
var oEditor = FCKeditorAPI.GetInstance('P59_CONTENT');
var clob_ob = new apex.ajax.clob(
function(){
var rs = p.readyState
if(rs == 1||rs == 2||rs == 3){
$x_Show('AjaxLoading');
}else if(rs == 4){
$x_Hide('AjaxLoading');
$s('P59_CONT', p.responseText);
doSubmit(request)
}else{return false;}
$x('P59_CONT').value = oEditor.GetHTML();
oEditor.SetHTML('');
if(!$v_IsEmpty('P59_CONT')){clob_ob._set($v('P59_CONT'))};
The submit calls a process that inserts the data from the clob001 field in the CLOB_CONTENT collection into my table.
How do I get the data out of the table again to present in the HTML Editor? Each option I use gets me into trouble with the 32k length limitation that is extant in Apex. What would be the best way to address this?

Inserting or retrieving a clob in the database is simple and can be done with a pl/sql process. It gets more more complex when the clob is large; I believe the limit is 32k? Larger than that and the HTTP process cannot manipulate the data stream.
The key to manipulating clobs successfully is through the use of collections, and javascript. In my case, I used the standard html editor item (fckeditor) to retrieve the data and present it on the page through the apex.ajax.clob javascript function. The clob_set method in the apex.ajax.clob function that I mention in the previous sections of this post calls the 'doSubmit(request)' that causes a pl/sql function to be fired that writes the clob to the database from the collection created by the clob_get method. The collection that the clob_get method creates is called 'CLOB_CONTENT', and can be accessed through the 'apex_collections' view through standard sql within APEX. In my case, the pull the 'clob001' field from the 'CLOB_CONTENT' collection after the clob_set method runs, and I insert the value from 'clob001' into the table I have created for storing the clob content. The clob_set pulls the data from the HTML editor (FCKeditorAPI.GetInstance('P59_CONTENT')) through the GetHTML() method that is part of the FCKeditorAPI.
function clob_set(request){
var oEditor = FCKeditorAPI.GetInstance('P59_CONTENT');
var clob_ob = new apex.ajax.clob(
function(){
var rs = p.readyState
if(rs == 1||rs == 2||rs == 3){
$x_Show('AjaxLoading');
}else if(rs == 4){
doSubmit(request);
$x_Hide('AjaxLoading');
}else{return false;}
var p_html = oEditor.GetHTML();
if (p_html){
clob_ob._set(p_html);
else {
p_html = ' '
clob_ob._set(p_html);
The clob_get method pulls the data from the 'CLOB_CONTENT' collection and puts it into the html editor item I have created, performing the process in reverse. The primary difference with reversing the process is that a pl/sql function is created that populates the clob001 field in the 'CLOB_CONTENT' collection prior to the clob_get function firing:
declare
l_clob clob:= empty_clob();
begin
if apex_collection.collection_exists(p_collection_name=>'CLOB_CONTENT') then
apex_collection.delete_collection(p_collection_name=>'CLOB_CONTENT');
end if;
apex_collection.create_or_truncate_collection(p_collection_name=>'CLOB_CONTENT');
dbms_lob.createtemporary( l_clob, false, dbms_lob.SESSION );
if trim(:P123_ID) <> 0 then
select
nvl (ltr,'There is no letter assigned.')
into
l_clob
from grant_tbl
where id = to_number(:P123_ID);
apex_collection.add_member(p_collection_name => 'CLOB_CONTENT'
,p_clob001 => l_clob
ELSE
apex_collection.add_member(p_collection_name => 'CLOB_CONTENT'
,p_clob001 => 'You must select an item to view its letter.');
end if;
end;
The clob_get function is below. Notice that the line "$s('P123_CONTENT',p.responseText);" is taking the output from the clob_get and setting the value of the P123_CONTENT page item (which is my standard html editor item) with the 'responseText'. the 'p' object and the 'responseText' method are built into the clob_get function when a 'new apex.ajax.clob' object is created. Confusing? Tell me about it!
function clob_get(){
var clob_ob = new apex.ajax.clob(
function(){
var rs = p.readyState
if(rs == 1||rs == 2||rs == 3){
null;
}else if(rs == 4){
$s('P123_CONTENT',p.responseText);
null;
}else{return false;}
clob_ob._get();
}

Query xml data from a CLOB datatye

All,
I read in an oracle white paper that is is possible to query XML data from CLOB datatype using oracle text index using operators HASPATH() and INPATH(). I am not able to find any example on how to do this. Can someone please post a simple example here.

Downloading data from a BLOB Field using mod_plsql

Hi,
I am trying to use the mod_plsql to download data from a blob field, I have a web page where I can pick the file name to be downloaded from the documents table This table has the BLOB field that has the Data formatted in a text file format(contains carriage returns), when I open it up in the browser it is displaying it correctly , but when I right click on the file name and choose "Save Target As" and save it as text file it is ignoring the carriage returns and displaying entire blob in one line.
Can somebody help me figure out why it's not recognizing the carriage returns?
Any help would be greatly appreciated.
Thanks

Hi and welcome to the forum.
Is there a way to retrieve data from a blob field and save it to temp table.Why would you want to do that?
Can you provide some more details regarding your requirement?
(Don't forget to mention your database version as well)
Also, I wonder why you've added a 'decompress' tag to your question?
edit, after seeing Tubby's reply
Dang, the connection must be frozen here ;)

Import/Export xml data from subtree of dynamic XFA form

Hi
We would like to import/export xml data (subtree) of a dynamic xfa form. The following script does only work with static AcroForms:
formular.content.subformDaten.Button1[1]::click - (JavaScript, client)
event.target.exportAsXFDF({aFields:["formular[0].content[0].subformDaten[0]"]});
With dynamic forms the script does export an empty xml file (no data is included, only xml root tag):
<?xml version="1.0" encoding="UTF-8"?>
<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve"
><f href="ExportTest_frei.pdf"
/><ids original="EA43F92A6B6EA34F9C4DBBC2DA0B1840" modified="6A7C6282A167594F91240B773AA979A7"
/></xfdf
>
Any ideas? Many thanks.
Best regards,
Daniel

Hi Paul
The Problem that Daniel posted was originally mine. Now after subscribing to this forum myself, I try to describe the aim of using exportAsXFDF/importAnXFDF.
exportData("", false) and exportXFAData works, in my opinion, only with a DataConnection. In my form I have indeed such a connection for sending the whole form. But in addition I need the possibility to export and import only part of the data without overwriting the rest of the filled form.
exportAsXFDF works with static forms. So there MUST be a possibility that works with dynamic forms, right?
I hope anyone has a solution.

Xml data from database using jdbc

I should get the xml data from database. Is this scenario possible using jdbc adapter ? If possible, how can I get it ?. Plz help me

I suppose that probably, xml data are stored in a BlobImage Field.
You can use a Stored Procedure on Database Side, to select and put out the xml data structured in output fields or structures.
From JDBC Sender channel, you can call the SP, that raise out a Structure formatted like the XML Data stored in Xml Database field.
In your opinion, this should be a possible way to achieve this issue?

Using REGEXP_REPLACE to remove XML data from between XML tags

Hello there,
I am trying to use the REGEXP_REPLACE SQL function on a piece of XML, to remove the actual XML data from the elements. My end goal is to end up with a comma-delimited list of XML element names. As part of the first step, I just want to rip out all the actual data.
I tested the following query, and it initially appeared to work:
SELECT REGEXP_REPLACE('>THIS IS A TEST<',
                      '>([[:alnum:]]\s|\S)*<',
                      '><' ) AS test_result
FROM dual;Unfortunately, when I applied this to a full XML string, it didn't work. Here is the test query I used:
SELECT REGEXP_REPLACE('<ROW><TEST_ELEMENT1>123</TEST_ELEMENT1><TEST_ELEMENT2>THIS IS A TEST!</TEST_ELEMENT2></ROW>',
                      '>([[:alnum:]]\s|\S)*<',
                      '><') AS test_result
FROM dual;I ended up with the following output:
*<ROW></ROW>*
What I was trying for was:
*<ROW><TEST_ELEMENT1></TEST_ELEMENT1><TEST_ELEMENT2></TEST_ELEMENT2></ROW>*
If you're reading this and you're a Posix RegExp Guru, please could you let me know exactly where I'm going wrong? RegExps are not my strong point, but I'd like to get better at them.

Export XML data into multiple worksheet of an Excel file..using FO processr

Hi,
I need to export XML data into Excel output, the data should flow into multiple worksheet of the Excel file.
Let me know if this can be done using XML publisher. If yes, please provide me the steps to do the same.
Could not able to achieve this through by the below process:
(1)     Created a RTF (which has single excel table structure).
(2)     Generated the XSL file using XSL-FO Style Sheet.
(3)     Passed the XSL file and XML
which exported the data into an Excel (single worksheet) format.
Please let me know, how this can be exported into multiple worksheets.
Thanks & Regards,

Hi Dhamodaran ,
pass me the template you created and XML. "Created a RTF (which has single excel table structure)."
Let me have a look at it,

I'm trying to read some XML data from temperature logger over my network. I'm using LabView version 2009 sp1. I'm using the URL Get Document Vi. It works fine when using Internet sites like google or foxnews etc...
When I use it with my temperature logger most of the time I get an Error 66...but some times it does work and actually retrieves the document.
I can use the same address "http://172.22.21.68/XMLfeed.rb" (Internet Explorer or Google Chrome) in my browser and get a response every time. When accessing from my browser the server in the temperature logger does take around 6 seconds to respond, but it does respond every time.
Is the URL Get Document Vi exceeding a timeout? If so, where can I set it to wait longer?

It looks like the TCP Buffered Read has a 2.5 sec timeout, I believe that is where I had trouble as well. Try creating your own URL Get HTTP Doc vi in which you call URL Get Document in normal mode, with an appropriate number of characters to fetch (enough characters so that you capture all the important data in the XML file).

How to read XML data stored in CLOB in Concurrent prog Output

Hi All,
I'm trying to Generate the XML Data as concurrent Program output. I have a PL/SQL package which generated the XML data by using SQL/XML functions. I'm storing the generated XML data in a CLOB variable. But when i try to read the data using fnd_file.put_line(fnd_file.OUTPUT,XML_Data) it doesn't display data more than 32767 bytes.
Please help me out to understand what could be done to read the data in chunks. I have tried many logic's to print chunks of data but the output tags are either chopped off and errors out saying Tag not found.
My logic is as below:
v_handler:= DBMS_XMLGEN.newContext(v_xml_query);
--Sets NULL handling options
DBMS_XMLGen.SetNullHandling(v_handler, dbms_xmlgen.EMPTY_TAG ) ;
--Set special character handling
DBMS_XMLGEN.setConvertSpecialChars(v_handler, TRUE);
-- Specified whether to use an XML attribute to indicate NULLness of particular entity in the XML document
DBMS_XMLGen.useNullAttributeIndicator(v_handler,TRUE);
-- set Checking invalid chars
DBMS_XMLGEN.setCheckInvalidChars(v_handler, TRUE);
-- get the xml data as required
v_xml_data:= DBMS_XMLGEN.getXMLtype(v_handler);
SELECT XMLROOT(v_xml_data.extract('/*'),VERSION '1.0').getClobVal() into v_new_xml_Data from dual;
-- get the length of the xml generated
v_clob_len := dbms_lob.getlength(v_new_xml_Data);
FND_FILE.PUT_LINE(FND_FILE.LOG,'The Clob length is :'|| v_clob_len);
-- logic to process string more than 32767 Processing by each character
v_offset :=1;
while (v_offset <= v_clob_len)
LOOP
v_char := dbms_lob.substr(v_new_xml_Data, 1, v_offset);
IF (v_char = CHR(10))
then
fnd_file.new_line(fnd_file.output, 1);
else
fnd_file.put(fnd_file.output, v_char);
end if;
v_offset := v_offset + 1;
END LOOP;
FND_FILE.PUT_LINE(FND_FILE.LOG,'The offset is :'|| v_offset);
FND_FILE.NEW_LINE(FND_FILE.OUTPUT, 1);
THe above logic is for character by character which is a performance burden? Please let me know if there is any other work around for this

Hi,
Thanks for Replying. I have refered http://blog.oraclecontractors.com/?p=69 and then i added that piece of code. Basically, i'm trying to generate a report using XML publisher. To generate the XML data i'm writing a pl/sql package with SQl/XML functions. DBMS_XMLGEN would help me convert the XML Data as is. When the concurrent program runs this XML data will merge with RTF layout and generate required report. I'm able to generate the Report for data less then 32767 bytes. More than the limit i need to pass chunks of XML data to read as output. That's the reason i'm using fnd_file.output. But it reads only 32767 size at a time.
WHen i use the given logic, it works perfectly fine, but it loops for each character, for example if you have 30,000 characters it loops the same, which is peformance burden.
So i tried to write the logic of chunks but still i get the error that XML tag is not found or missing. I'm hoping this is very common issue, but after all my trails, i didn't find the right solution.
the other logic i tried was :
v_new_xml_data varchar2(32767)
v_iterations := CEIL(v_clob_len/v_chunk_length); -- v_chunk_length is 32767 and v_clob_length is length of the XML data stored inthe clob variable
For i in 0..v_iterations
LOOP
FND_FILE.put_line (fnd_file.log,'the loops v_pos :'||i||' and v_clob_length :'||v_clob_len);
v_new_xml_data := DBMS_LOB.SUBSTR ( V_XML_DATA,v_chunk_length,(i*v_chunk_length)+1);
FND_FILE.PUT_LINE (FND_FILE.OUTPUT,v_new_xml_data); -- read the output for every 32767 chunks
FND_FILE.PUT_LINE(FND_FILE.LOG, 'Chunk length is :'||((i*v_chunk_length)+1));
END LOOP;
FND_FILE.put_line (fnd_file.log,'out of loop');
FND_FILE.put_line (fnd_file.log,'length of new xml is '||v_clob_len);
Please, let me know if you need Further clarifications on the same.

Update XML data stored in CLOB Column

Hi All,
i am new to Oracle and new to SQL
i am trying to update XML data stored in CLOB cloumn,data is stored with the follwoing format
<attrs><attr name="name"><string>Schade</string></attr></attrs>
i am using the following query for updating the value
UPDATE PRODUCT p SET ATTRIBUTES_nl_nl=UPDATEXML(XMLTYPE.createXML(ATTRIBUTES_nl_nl),'/attrs/attr[@name="name"]/string/text()','Schade').getClobVal() WHERE p.sku='000000000000040576_200911-5010057'
this query is working fine but it changing the data to the following format
<attrs><attr name="name">Schade</attr></attrs>
some how it is ommiting the <string> tag from it, i am unable to figure it out whats the reason.
any help in this regard will b e much appriciated
Thanks in Advance

Hi,
You should have created your own thread for this, and included database version.
This works for me on 11.2.0.2 and 10.2.0.5 :
SQL> create table t_org ( xml_clob clob );
Table created
SQL>
SQL> insert into t_org
2 values(
3 '<Message>
4 <Entity>
5 <ASSIGNMENT>
6 <OAVendorLocation> </OAVendorLocation>
7 <Vendorid>1</Vendorid>
8 </ASSIGNMENT>
9 </Entity>
10 </Message>'
11 );
1 row inserted
SQL> commit;
Commit complete
SQL> select '*' ||
2         extractvalue(xmltype(xml_clob),'/Message/Entity/ASSIGNMENT/OAVendorLocation')
3         || '*' as result
4 from t_org;
RESULT
SQL> update t_org set xml_clob =
2 updatexml(xmltype(xml_clob),
3 '/Message/Entity/ASSIGNMENT/OAVendorLocation/text()','LONDON').getClobVal()
4 ;
1 row updated
SQL> select '*' ||
2         extractvalue(xmltype(xml_clob),'/Message/Entity/ASSIGNMENT/OAVendorLocation')
3         || '*' as result
4 from t_org;
RESULT
*LONDON*
Does the OAVendorLocation really have a whitespace value?
If not then it's expected behaviour, you're trying to update a text() node that doesn't exist. In this case, the solution is to use appendChildXML to create the text() node, or update the whole element.
Is it your real document? Do you actually have some namespaces?

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.
