Updating CLOB in Oracle 8i

We are using Oracle 8i.
And I need to update country code inside the message body. Please help me.
Sample table structure
CREATE TABLE test_xml_tab ( message_id NUMBER,
message_body CLOB);

Problem updating CLOBs across multiple schemas

I am having a problem trying to update CLOB data in a schema owned by a user other than the logged-in user.
Suppose I have user UA who owns table TA and user UB who owns table TB, and TA and TB contain CLOB columns. TA owns a package PA and TB owns package PB; these packages provide functions for updating the CLOB data via LOB locators.
I have a JDBC connection logged on as user UA, and I can successfully call package PA to update the CLOB data in TA from my Java app. However, I cannot use this connection to similarly call package PB to update the CLOB data in TB - the app successfully calls CallableStatement.executeUpdate() but then I try to get the output stream of the returned CLOB:
oracle.sql.CLOB oOraClob = (oracle.sql.CLOB)oCall.getClob(SQLPAR_CLOBCOL);
Writer oOut = oOraClob.getCharacterOutputStream();
and I get the following exception on the getCharacterOutputStream() call:
java.sql.SQLException: ORA-01031: insufficient privileges ORA-06512: at "SYS.DBMS_LOB", line 498 ORA-06512: at line 1
This is despite user UA having execute privilege on PB and update on table TB.
I only get this problem when I try to update the CLOB directly from JDBC - I have another function in package PA which copies CLOB data directly from TA to TB and that works without any problem. Given this, I tried writing a procedure in PA to act as a kind of proxy between PB's CLOB-update function and user UA, i.e. UA calls a proc in PA which in turn calls PB which returns a LOB locator to PA, which in turn returns the LOB locator to user UA, but this still gave the same error.
Does anyone know what might be causing the problem? Is there some user permission I'm missing?
I don't want to have to use a separate DB connection as user UB just to update the CLOB. The only other solution I can see at present is to pass the string data to PA as a LONG and have PA copy the data to the LOB locator returned by PB. How could I achieve this? Is there a built-in function which enables a LONG to be copied to a CLOB?
Any help would be very much appreciated. Thanks.

Ian - You can use a different schema for each application while keeping the applications in a common workspace. This would allow users to authenticate once and for the applications to share the same authenticated session. In doing this, however, a user has to be given links from one application to another, e.g., from a menu page, in order for the "session continuity" to remain unbroken (a requirement to prevent another login challenge). But since these may be unrelated applications that have no need to access one anothers' session state, it might be better to use Single Sign-On. With this method there is only one login required and a user can access each application which will maintain its own private session.

Insert CLOB into oracle under weblogic

Situation: running my servlet under weblogic, want to insert more than 4000 characters into CLOB of oracle 8.1.7
Problem: cannot be done by using code which is able to do it under tomcat
i use this code in tomcat:
import java.sql.*;
import oracle.sql.CLOB;
import oracle.jdbc.driver.OracleResultSet;
con.setAutoCommit(false);
Statement stmt = con.createStatement();
rs = stmt.executeQuery("SELECT clob_field FROM table where rid=id FOR UPDATE");
rs.next();
CLOB clob = ((OracleResultSet)rs).getCLOB(1);
Writer writer = clob.getCharacterOutputStream();
writer.write(dataString);
writer.close()l
con.commit();
con.setAutoCommit(true);
stmt.close();
after that i know that i can't use API of oracle when i'm using weblogic (e.g. oracle.sql.CLOB)
and i find this code from other user:
import weblogic.jdbc.vendor.oracle.OracleThinClob;
import java.io.*;
import java.sql.*;
PreparedStatement stmt = con.prepareStatement ( "INSERT INTO database VALUES ( ?, EMPTY_CLOB() )" );
stmt.setInt ( 1, 1 );
// inserts a new entry with an empty clob object
stmt.executeUpdate ();
if ( stmt != null )
stmt.close();
// retrieves CLOB-Object
stmt = con.prepareStatement ( "SELECT clob_field FROM database WHERE id=?" );
stmt.setInt ( 1, 1 );
ResultSet rs = stmt.executeQuery ( );
if ( rs.next() )
Clob cl = rs.getClob(1);
Writer clobWriter = ((OracleThinClob)cl).getCharacterOutputStream();
// Open the sample file as a stream for insertion into the Clob column
File testFile = new File ( "file.txt" );
FileReader testReader = new FileReader ( testFile );
// buffer to hold data to being written to the clob.
char[] cBuffer = new char[((OracleThinClob)cl).getBufferSize()];
// Read data from file, write it to clob
int iRead = 0;
while( (iRead= testReader.read(cBuffer)) != -1 )
clobWriter.write( cBuffer, 0, iRead);
testReader.close();
clobWriter.close();
if ( rs != null )
rs.close();
if ( stmt != null )
stmt.close();
// update clob-data in database
stmt = con.prepareStatement ( "UPDATE database SET clob_field = ? WHERE id = ?" );
stmt.setClob ( 1, cl );
stmt.setInt ( 2, 1 );
stmt.executeUpdate();
it throws java.lang.ClassCastException: oracle.sql.CLOB
but i haven't imported or used any API from oracle.........
please help
thanks

hi,
unfortunatly, you can't do this with welbogic6.1 because it 'manage' itself oracle librairies (weblogic.jar),
here is the way i solved the pb for BLOB :
i replaced :
BLOB blob = ((OracleResultSet)rs).getBLOB(1);
by
weblogic.jdbc.rmi.SerialOracleBlob cast1 =(weblogic.jdbc.rmi.SerialOracleBlob)rs.getBlob("myBlob");
weblogic.jdbc.rmi.internal.OracleTBlobImpl cast2 =(weblogic.jdbc.rmi.internal.OracleTBlobImpl)cast1.getTheRealBlob();
BLOB myBlob = (oracle.sql.BLOB)cast2.getTheRealBlob();
it is the same for clob (i suppose ^_^)
hope this helps !
Badr.

COMPONENT NAME: LKM Oracle to Oracle (datapump)
COMPONENT VERSION: 11.1.2.3
AUTHOR: Oracle
COMPATIBILITY: ODI 11.1.2 and above
Description:
- Loading Knowledge Module
- Loads data from an Oracle Server to an Oracle Server using external tables in the datapump format.
- This module is recommended when developing interfaces between two Oracle servers when DBLINK is not an option.
- An External table definition is created on the source and target servers.
- When using this module on a journalized source table, the Journaling table is first updated to flag the records consumed and then cleaned from these records at the end of the interface.

Difference in select for update of - in Oracle Database 10g and 11g

Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience):
DECLARE
  v_ename bonus.ename%TYPE;
BEGIN
  SELECT b.ename
    INTO v_ename
    FROM bonus b
    JOIN emp e ON b.ename = e.ename
    JOIN dept d ON d.deptno = e.deptno
   WHERE b.ename = 'Scott'
     FOR UPDATE OF b.ename;
END;
/While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?
Edited by: Libor Nenadál on 29.4.2010 21:46
It seems that my question was answered here - http://stackoverflow.com/questions/2736426/difference-in-select-for-update-of-in-oracle-database-10g-and-11g

The behaviour seems like it really is a bug and can be avoided using non-ANSI syntax. (It makes me wonder why Oracle maintains two query languages while dumb me thinks that this is just a preprocessor matter and query engine could be the same).

How can I get the content of clob in oracle db?

In jsp,if I want to get the characters from CLOB column in ORACLE DataBase,what should I do?
I am waiting for the answer hurrily.Thank you!

import these two classes:
import oracle.sql.CLOB;
import oracle.jdbc.driver.OracleResultSet;To retrieve the clob, use
              ResultSet rs;
                  get the rs from database
              int i = 1; // this is the column Index in the rs
              CLOB cl = ((OracleResultSet)rs).getCLOB(i);
              int len = (int)cl.length();
              String str = cl.getSubString(1,len);

Which is better: Oracle incremental update (merge) or Oracle incremental update

Hi All,
We have big data load happening from Oracle RDBMS(source) to Oracle RDBMS(target). The data is huge (in billions) and new insertions, updates will happen. I would like to understand which among
Oracle incremental update (merge) or Oracle incremental update is better and faster - for first load and subsequent incremental updates, deletes? I request you all to provide valid reasons since I need to present the same to my client
If at all Oracle incremental update (merge) is better, then why ODI needs to have Oracle incremental update IKM.
I have seen some discussions on the same topic but I have not yet got a proper response with reasons and that is why I am posting the question again
Thanks & Regards,
Sijee Sadasivan

Hi Sijee Sadasivan,
IKM SQL Control Append could be faster for the initial load. You will therefore need another interface for the initial load.
From my experience IKM Oracle Incremental Update (Merge) is faster than IKM Oracle Incremental Update for the incremental load, but I think the best thing to do is to try it on your environment. Nothing is better than a benchmark .
IKM Oracle Incremental Update is useful for Oracle RDBMS < 9i, before this syntax was introduced.

Writing an update statement in oracle forms 9i

Hi ,
I have a problem situation in which
I am fetching values from a cursor and a recod group into two data block items text box and combo box respectively .
Both the data is fetched from different tables .
Now based on the selection from combo box I have to update the selected value in another table by writing an update statemet .
I have created a button and on the trigger event of when button pressed I wrote a simple update statement but it's not working that way .
Kindly help me how to write manual update statements in oracle forms 9i
I can't used the update buil in of forms as I want to update in a table which is not mentioned in the property pallete of data block
please help

I just wrote a procedure
PROCEDURE update_current IS
BEGIN
update table abc set xculumn= :block_name.item_name2 where ycolumn = :block_name.item_name1 ;
commit;
and I called the procedure from a when button pressed trigger
it gave an error invalid identifier abc ( which is table name)
pls help
I am trying to do it with form_ddl(update_query)
but here I am facing another problem
I have update_query = 'update table abc set xculumn= ' || :block_name.item_name2 || 'where ycolumn = '||:block_name.item_name1
now since xculumn and y column are varchar type so I suppose while preparing the query I have to concatenate single quotes ( ' ) at the start and end
but i am facing problems in doing so
please tell me an alternative way or how to concatenate single quotes in the above update_query variable

How to update column in Oracle SQL Developer?

Hi everybody,
How can I update table in Oracle SQL Developer like in PL/SQL Developer use:
Select * from table for update;
Thank you~

Do you mean you want to edit the result grid?
You can't edit the result grid of a query, but you can edit the data tab of a table.
Click on the table in the object browser
Click on the data tab
Optionally filter the results using the filter field at the top
Type into the data cells.

Converting Varchar into Clob in Oracle 8i

Hi All,
Kindly tell me how can we convert a varchar variable into a Clob in Oracle 8i inside a stored procedure. I searched alot on the net, we have a To_Clob function available from 9i but doesn't exist in 8i. There was also talk about using dbms_lob, but i dont know how to use that to convert it.
Kindly provide me with the details of how to do this as I am just starting out with Oracle.
Thanks in Advance,
Sajid.

Hi,
You can use the dbms_lob.to_clob() function(In oracle8i).
In oracle 9i it is not required.
Thanks & Regards

Accessing CLOBs in Oracle 8i

From the research i've done, it seems that there are two ways to access CLOBs in Oracle 8i: InputStream or Reader.
The InputStream method uses byte streams and the Reader uses character streams.
Is that correct? I haven't been able to determine the pros/cons of the two approaches. Can anyone shed some light on this for me?

Jack Shirazi claims in his book, "Java Performance Tuning", that in most situations Readers provide better performance than InputStreams.
Read the section, "From Raw I/O to Smokin' I/O", in Chapter 8 for details.

To update my remote oracle server through e mail

hai,
i want to update my remote oracle server through e mail which should run automatically for every 3 hours(for example)

Please let me know how to go about....
help me in this context...

Sri
you can do with some SMTP programming like that one available in VisuaBasic. you can read the mail from an inbox
from a mail account of an SMTP SERVER. Then you may try to update the remote database.
Well i have mentioned VB as i heard it long back from my GURUJI that it is possible thru SMTP programming in VB
using the socket controls etc,.
Please check it out in some visuabasic forum sites and ask some VB Gurus.

Using eclipse Web services to retrieve and update data to Oracle DB

Hi,
Can I have a sample about to use eclipse to retrieve/update data from Oracle DB by using axis web services?
thank you

Hi,
If you have a sheet in Excel with data from a SharePoint Online list you can switch to the PowerPivot ribbon and ask to add it to the model. This will allow you to reference this table when you create a PowerView report.
This workbook, with the Odata feed can then be refreshed via the scheduled refresh feature of Power BI Site.
Insert the data using the Odata feed
The Odata URL will be something like:
https://MyCompany.sharepoint.com/MySite/MySubSite/_vti_bin/listdata.svc/MyList
If you are not sure what is the list name, you can drop just browse to
https://MyCompany.sharepoint.com/MySite/MySubSite/_vti_bin/listdata.svc and this will provide a list of all the lists in that site/sub-site.
Once you have those in the model and you setup scheduled refresh, it will refresh the lists directly from SPO (using the owner identity)
Hope this helps.

Problem installing Oracle Linux Release 5 Update 2 from Oracle e-Delivery

Hello
I have been trying to install Oracle Linux Release 5 Update 2 from Oracle e-Delivery so that I can install Oracle 11g express edition beta.
Here are the steps that I took and the problem that I am having:
1. I downloaded the file, unzipped the file twice, which gave me 3,042 files and 13 folders with the total size = 3.07 GB.
2. I put in the DVD and restarted my PC hoping that my PC will boot from the DVD, but instead Window started.
I reported this issue to tech support from e-Delivery, but they referred me to contact you. Please assist.
Julia

3,042 files and 13 folders with the total size = 3.07 GBWhich download .zip did you choose from edelivery? Under linux-x64 I peeked "Oracle Linux Release 5 Update 2 for x86_64 (64 Bit) - DVD" file V15099-01.zip downloaded, it has just the one .iso file. You'll need to burn that to DVD, but with burn s/w that handles ISO files.
Also keep in mind you'll need 64 bit hardware (amd/intel 64? itanium? those are different), the only *nix platform I've got handy to try it out is -x86 :(
