Setting clobs
how are clobs in java set?
setClob gives an error of setClob(int,javasql.Clob) in java.sql.PreparedStatement cannot be applied to (int, Java.lang.String)
That error means you are trying to pass a String instead of passing a CLOB. You need a CLOB as a second argument.

Insert into CLOB fails with Oracle ODBC driver version 9.02.00.65
I tried to insert into CLOB using the latest Oracle ODBC driver 9.02.00.65 and it fails. But the same works with earlier versions of ODBC driver earlier to 9.02.00.65 ie., 9.02.00.63.
Here is the code snippet I tried. Any help now is highly appreciated as I am in the crunch time.
I tried the same code snippet with VARCHAR2 column with the same driver and it works.

Since 9.2 has been desupported for error correction you will not be able to download that version from OTN. You should ask whoever is providing the training if their is an alternate version you can use. The only versions that you will be able to download from oracle.com is 10.2 11.1, and 11.2. -
Portal 4.0 with MS SQL Server 2000 using CLOBs
Hello,
I'm driving Portal 4.0 with MS SQL Server 2000. I have encountered serious
problems when trying to persist events (e.g. RuleEvent) to database. In my
application-config.xml file I have JdbcHelper attributes
ShouldUseClobsForReads & -Writes set to 'false' as they should be or
mssqlserver4v70 driver.
It seems that when it is time to write the event to database, Portal4.0
can't find JdbcHelper MBean configuration values and therefore it uses
default values (=true) for both attributes.
Otherwise reading and writing works fine with MS SQL Server 2000 (at least
DATA_SYNC_ITEMs).
Any help appreciated.
Regards,
JR
P.S.
Here are some excerpts from the console output:

We developed a SSIS Package to pull the data From Oracle source to Sql Server 2012. Here we used ADO.Net source to pull the records from Source but getting the below error after pulling some 40K records.
[ADO NET Source [2]] Error: The ADO NET Source was unable to process the data. ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.
The PrimeOutput method on ADO NET Source returned error code 0xC02090F5.
The component returned a failure code when the pipeline engine called PrimeOutput().
The meaning of the failure code is defined by the component,
but the error is fatal and the pipeline stopped executing.
There may be error messages posted before this with more
information about the failure.
Anything that we can do to fix this?Hi,
Tried both....
* Having schema type as Nvarchar(max). - Getting the same error.
* Instead of ADO.Net Source used OLEDB Source with driver as " Oracle Provide for OLE DB" Getting error as below.
[OLE DB Source [478]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on OLE DB Source returned error code 0xC0202009. The component returned a failure
code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the
failure.
Additional Info:
* Here the Source task is getting failed not the conversion or destination task.

XML data from BLOB to CLOB - character set conversion
Hi All,
I'm trying to solve a problem with a character set conversion in PL/SQL in the following scenario:
1. source is an XML as a BLOB variable.
2. target is an XML as a CLOB variable.
3. the problem I have is the following:
- database character set is set to UTF-8
- XML character set could be anything (UTF-8, ISO 8859-1, ISO 8859-2, ASCII, ...)
- I need to write a procedure which converts the source BLOB content into the target CLOB taking into account the XML encoding and converts it into the DB default character set (UTF8).
I've been able to implement a simple conversion function. However, this function expects static XML encoding ISO-8859-1. The main part of the function looks as follows:
buffer := UTL_RAW.cast_to_varchar2(
UTL_RAW.convert(
DBMS_LOB.SUBSTR(source_blob_variable, 16000, pos)
, 'American_America.UTF8'
, 'American_America.we8iso8859p1')
Does anyone have an idea how to rewrite the code to handle "any" XML encoding in the source BLOB file? In other words, is there a function in Oracle which converts XML character set names into Oracle character set values (ISO-8859-1 to we8iso8859p1, UTF-8 to UTF8, ...)?
Thanks a lot for any help.
JuliusI want to pass a BLOB to some "createXML" procedure and get a proper XMLType in UTF8 character set, properly converted from whatever character set is the input in.As per documentation the generated XML has always the encoding set at the client side depending on NLS_LANG (default UTF-8), regardless of the input encoding, so I don't see a need to parse the PI of the XML:

Setting Line Terminator for a CLOB column by script
Hello Everyone,
I have a CLOB column in my table that receives external data (more than 400 sources).
The GUI application displays it in different ways because of the multiple incoming Line Terminators.
Here is the weird thing:
In SQL developper 3.1.06. In the Preferences->Environment I selected as Line Terminator: Carriage Return and Line Fe(Windows)
Once I committed the changes the data was properly displayed in the application (apparently was also re-coded).
My Question is:
How can I setup this property on the column or table to fix the issue??
(I'm looking for a DDL script or something alike).
Thanks in advance.
Mijail O. T.914451 wrote:
If that's the case, What is the SQL DEveloper doing then??
I tested and looks like is a global parameter, not sure if works only for the table. (That what I need).
If is possible to setup this feature from the GUI it should be a way to do it running a Script.
Right????No.
Tables don't have any concept of "lines".
CLOB's don't have any concept of "lines".
"lines" only exist in the context of the data you are providing, but that's not of concern to the database.
So it looks like, what SQL Developer is doing (I assume as I don't use it), is to have a setting such that when it comes to display character data from VARCHAR2's or CLOB's it determines if there are CR/LF or just LF characters (as per the setting) and then uses those as line terminators for displaying the data in it's own interface. Thus it sounds like an interface specific setting, or to put it bluntly, it's something that is a part of SQL Developer to control how it displays things.
Have you tried querying back the raw version of the data from the database to see that it still has the CR/LF characters in it? It should.
I think you'll find the setting is a "display" setting, not a "alter my data" setting. -

Urgent: How to set a default value to CLOB field?
Hi All,
As per the requirements we have to populate the CLOB field in a template with default value with some template similar to a letter issued to clients in bank.
So, every time when I insert a record in that table this CLOB field should have that letter template populated by default and user will modify that if required from GUI.
How can I populate that CLOB field by default?
Thanks!Something like this?

How do I set a maximum length (in characters) of a CLOB field
Hi,
I've seen some questions like this around, but I did not find a clear answer.
This is my problem: I want to make my CLOB field to accept a maximum of 32768 characters. This is because I need other data manipulation tools to receive an ORA error when they try to insert or update text larger than 32768.
I tried with an Insert/Update trigger, but I received ORA error that actually means that LOB fields can not be used in update trigger(or something).
Please, help!Maybe, Not a neat way to do things, but seems to work.
Others may be able to suggest better solutions.

Help!!urgent!!can not insert/update clob:the row containing the lob is not locked
Hi,
could you do me help?
i can not insert a string into a oracle clob field, it echo as:
ORA22920 row containing the lob value is not locked. ORA 06512 at "SYS.DBMS_LOB" line 708
ORA 06512 at line 1;
what its means? please.
my table defined as : create table clob1(id number(5),mclob clob default empty_clob()); the id is create by a sequece of test_sequence automaticly.
my code as belows:
import java.io.*;
import java.sql.*;
//import oracle.sql.*;
public class test4 {
public static void main(String args[]) {
String url_String
= "jdbc:oracle:thin:test/test@myhost:1521:myorcl";
try {
Class.forName
("oracle.jdbc.driver.OracleDriver");
java.sql.Connection con =
java.sql.DriverManager.getConnection(url_String);
con.setAutoCommit(true);
Statement stmt
=con.createStatement();
String sqlStr ="insert into
clob1 (mclob) " + "values(empty_clob())";
stmt.executeUpdate(sqlStr);
String query = "select
test_seq.CURRVAL from dual";
ResultSet rs =stmt.executeQuery
(query);
rs.next();
int currval =rs.getInt(1);
query = "select * from clob1 where
id="+currval;
String str
="abcedefhijklmnopqrstuvwxyz";
rs =stmt.executeQuery(query);
rs.next();
java.sql.Clob clob1
=rs.getClob(2);
oracle.sql.CLOB clob=
(oracle.sql.CLOB)clob1;
System.out.print(clob);
java.io.Writer
wr=clob.getCharacterOutputStream();
wr.write(str);
wr.flush();
wr.close();
stmt.close();
con.close();
} catch(Exception ex) {
System.err.println("SQLException: "
+ ex.getMessage());
nullHi,
To avoid ORA-22920 error while selecting lob column, use the 'for update' clause in the select statement like :
query = "select * from clob1 where id="+currval+" FOR UPDATE" ;
This should solve the problem. However, after fixing this, you might get the error :
java.sql.SQLException: ORA-1002: fetch out of sequence
I got this error when testing your code. To avoid this error, before executing 'select ... for update' statement Set AutoCommit to OFF, like :
query = "select * from clob1 where id="+currval+" FOR UPDATE" ;
con.setAutoCommit(false);
rs =stmt.executeQuery(query);
Hope that Helps,

PL/SQL Limit When Dealing with a CLOB?
Greetings,
I am constructing HTML into a CLOB in a PL/SQL routine which I later display in an APEX application. The HTML can get large, because I am constructing a grid over an image, and the grid can have a lot of columns and rows which means there can be a lot of <area shape="rect" HTML lines. I did a search and found that another person had the same problem, because there is a 32K limit with HTML contents. That was very helpful.
Thing is - I have another (maybe similar) issue. The procedure that constructs the HTML gets a numeric error when the number of cells in the grid reach a certain point. I checked and this happens when the CLOB in the procedure gets close to 32K. Sorry, it difficult to know exactly when it fails, but the most I have been able to put into the CLOB is 32,852 characters. Therefore my question - is there in internal limit in PL/SQL (or some other Oracle aspect) that is limited to 32K? The coluimn in the table that contains the HTML is a CLOB and the variable in the PL/SQL that the HTML is parsed into is a CLOB, so I thought I was good to go since the CLOB limit is 4GB. But, it looks like I may be missing something.
We are running Oracle 11i and APEX 4.0.2.00.07. If other system info is needed let me know and I will get that for you.
Also, if it helps. The code from the procedure is copied below. v_html is the variable that holds the HTML. The table column for the HTML is imagemap_html. Both v_html and imagemap_html are defined as CLOB's.
Thanks, Tony

END create_grid;Edited by: cloaked on Nov 7, 2011 4:45 AMFor "Application Express 4.2.1.00.08" i created such good solution.
I downloaded freeware plugin "Enkitec Clob Load Plug-in Version: 1.0.0 - APEX Version: 4.2.0" from there:
http://www.enkitec.com/products/plugins/clob-load/help
Then i followed plugin installation steps and created a APEX page where i added an item of type "Rich Text Editor".
I found the plugin crashes when my database CLOB field is empty, also crashed when i tried to save down empty value to database.
I changed Plugin code a little, and now everything works as needed, i can save down larga data, and also empty data.
1. In Apex open plugin "Enkitec CLOB Load".
2. Navigate to "Source-->PL/SQL Code" where is text area with plugin source code.
3. there you have such code:

How to set up SSO between e-portal employee node & ebill customer node?
We have a requirement to set up SSO between e-portal employee node & ebill customer node.
I am told that sso is possible only between 2 employee nodes.
Please advise.Not sure I understand which part is failing.
Is it the C program calling your packaged function? Or does the error occur in the PL/SQL code, in which case you should be able to pinpoint where it's wrong?
A few comments :
1) Using DOM to build XML out of relational data? What for? Use SQL/XML functions.
2) Giving sample data is usually great, but it's not useful here since we can't run your code. We're missing the base tables.
3) This is wrong :
vStrSqlQuery := 'SELECT * FROM ' || vTblName || ' WHERE record_update_tms <= TO_DATE(''' || TO_CHAR(vLastPubTms, 'MM/DD/YYYY HH24:MI:SS') || ''', ''MM/DD/YYYY HH24:MI:SS'') ' ;
A bind variable should be used here for the date.
4) This is wrong :
elmt_value := xmldom.createTextNode (doc, l_clob(1));
createTextNode does not support CLOB so it will fail as soon as the CLOB you're trying to pass exceeds 32k.
Maybe that's the problem you're referring to?
5) This is most wrong :
l_clob(1):=REPLACE(l_clob(1),'<?xml version="1.0"?>', NULL);
l_clob(1):=REPLACE(l_clob(1),'<', '<');
l_clob(1):=REPLACE(l_clob(1),'>', '>');
I understand what you're trying to do but it's not the correct way.
You're trying to convert a text() node representing XML in escaped form back to XML content.
The problem is that there are other things to take care of besides just '<' and '>'.
If you want to insert an XML node into an existing document, treat that as an XML node, not as a string.
Anyway,
Anyone that can help me to find out the required magic number
That would be a bad idea. Fix what needs to be fixed.
And please clearly state which part is failing : the C program or the PL/SQL code?
I'd vote for PL/SQL, as pointed out in [4]. -
Hello,
I am new to XML and have been trying this for few days and get no luck ...
First, I have an Excel file, which contains a list of bills for customers. It is a sample file to test my application.
In the future, my application will receive data of XML-datatype, so my job here is to import this Excel file into my Oracle database 11gr2, then transform it to XML datatype one.
I did import it by using Oracle SQL Developer and nicely stored it in a table called so_lieu.
After that, I run the following code to convert the table data to XML datatype:
CREATE TABLE xmlDoc(temp CLOB);
DECLARE
qryCtx DBMS_XMLGEN.ctxHandle;
temp CLOB;
BEGIN
qryCtx := DBMS_XMLGEN.newContext('SELECT * FROM huy.so_lieu');
-- Set the row header to be bill
DBMS_XMLGEN.setRowTag(qryCtx, 'bill');
-- Get the result
temp := DBMS_XMLGEN.getXML(qryCtx);
INSERT INTO xmlDoc VALUES(temp);
--Close context
DBMS_XMLGEN.closeContext(qryCtx);
END;
It is a success:
table XMLDOC created.
anonymous block completed
When I run: SELECT * from xmlDoc; I can get a data of XML-datatype as following:
<?xml version="1.0"?>
<ROWSET>
<bill>

</bill>
</ROWSET>
Then I try to select/query the XML elements inside that XML data (to parse them into another tables) but cannot. I tried:
SELECT XMLQuery('
for $x in ora:view("xmlDoc")/ROW
return $x/TEMP/ROWSET/bill/MA_CQTT
' RETURNING CONTENT) FROM DUAL;
It gave errors
ORA-19276: XPST0005 - XPath step specifies an invalid element/attribute name: (ROWSET)
19276. 00000 - "XP0005 - XPath step specifies an invalid element/attribute name: (%s)"
*Cause: The XPath step specified invalid element or attribute name that did not match any nodes according to the input XML schema or structure.
*Action: Correct the element or attribute name as the name may be mis-spelled.
I read several threads and think that maybe my ROWSET element is not XML anymore. Thus, cannot select using XPath. How can I fix it?
Thank you in advance,
Huy Do.
PS: I tried using XMLTABLE as below:
SELECT x2.*
from XMLDOC h,
XMLTABLE(
'//ROWSET/bill'
PASSING xmltype(h.temp)
COLUMNS ma_cqtt varchar(20) path 'ma_cqtt'
) x2
The query gave me a table of 2566 row of "ma_cqtt" but their value are all "null" (excel file has 2566 rows of record)
Message was edited by: 2716502Thank you Odie I tried:
INSERT INTO DM_TABLE (ma_cqtt, account, thang_ps)
select x.ma_cqtt
, x.account
, thangps as thang
Of course it returned an error, how silly of me to complicate thing like that
And I have one more question about the speed to parse a xml data. Please, help me with it.
In my code, I usually store xml data as a row in a temporary table (table mau_so_lieu). Then when doing parsing, I call the xml data from that table and the processing time is usually ~0.5s only. The code is like below:
INSERT INTO mau_so_lieu VALUES(xmlData);
INSERT INTO DM (
ma_kh, account, thang_ps)
select x.ma_kh, x.account, thang
from mau_so_lieu m, xmltable
('//Bao_cuoc'
passing m.BILL
columns
ma_kh varchar2(20) path '@ma_cqtt'
, account varchar2(20) path '@account'
) x;
But one of my senior (SQL server expert) suggested to store xml data in a variable (xmlData XMLType) as he thought the processing time will be even shorter, as well as no temporary table needed (no trash left which need to be cleaned later). I tried that but somehow the processing time is > 5s with the code as below:
INSERT INTO DM (
ma_kh, account, thang_ps)
select x.ma_kh, x.account, thang
from xmltable
('//Bao_cuoc'
passing xmlData
columns
ma_kh varchar2(20) path '@ma_cqtt'
, account varchar2(20) path '@account'
) x;
Could you tell me why the processing time are so different? Is it because of the default RAM of Oracle XE 11g is too small to process?
Thank you very much,
Huy Do.
