Read japanese char from oracle

I have a database column stores japanese char in Shift-JIS encoding. A
perl script can read the database and display the result on browser.
But If i try the get the japanese string in Java using JDBC. I got an
exception:
String text = resultset.getString(1);
Exception in main(): java.sql.SQLException: Fail to convert between
UTF8 and UCS2: failUTF8Conv
I wonder why I getting this exception and how to fix this?
thanks

Hi
We had faced the same problem.
Problem was with oracle jdbc thin driver.
We change the driver from THIN to OCI that works fine.
Try this option and pls let me know.

Problem with Pro*C reading BLOB field from Oracle 10g

Hello Experts,
We have a Pro*c application which is reading the BLOB data fields (a PNG image file) from Oracle data base. It holds the BLOB fields returned from the SQL query into a Unsigned Char structure in Pro*C. The program used work fine on AIX 32 – bit 4.3 and Oracle 8.1 environment.
Recently, we have upgraded the environment to AIX 64-bit 5.3 and Oracle 10g.Since after the Pro*c program has problem in reading the Blob filed.
Below is the query we are trying to execute –
EXEC SQL
SELECT
signtre_image, image_file_name_ext
INTO
:msipLocalImage INDICATOR :msipLocalImage_i,
:file_name_ext INDICATOR :file_name_ext_i
FROM
dcs_sign
WHERE
signtre_nbr = :signtre_nbr;
Here signtre_image is the BLOB fields and msipLocalImage is a Pro*C structure define as below –
typedef struct tagSignImage
long len; /* Image length */
unsigned char img[1]; /* Pointer to first byte. */
} MOTS_SIGN_IMAGE;
The quesry does not give any error or exception message in the Pro*C , program just stops at the point of executing the quesry..When we run the query commenting the BLOB filed it works fine. Also, the query runs good when we run it in the Oracle editor.
There seems to be problem with the way we are reading the BLOB field in the new Oracle 10g enviromet.
Does any body have any idea what’s wrong with this query? We really need it to work.
Any Help will be greatly appreciated.
Thanks,
- Rajan Yadav

Thanks a ton for your response.
We made the necessary changes as suggested by you.This time we got another flavour of error - SQL Error Code - Inconsistent error while reading BLOB.
Another thing we noticed is that the data field which we are trying to read is defined as LONG RAW instead of a BLOB in data base.
Are these two things related in any sense or is there anything else which is causing the error.
Once again Thanks for your help.

Problem with reading special char from file

Hello Oracle community,
Got a problem when reading from a file. I am using a croatian keyboard and trying to read special charachters (ČĆŽŠĐ) from a file.
declare
l_file utl_file.file_type;
s varchar2(200);
begin
l_file := utl_file.fopen('test_dir', 'test.txt', 'R');
loop
    utl_file.get_line(l_file, s);
    dbms_output.put_line(s);
end loop;
exception
when no_data_found then
    utl_file.fclose(l_file);
end;But I keep getting this in dbms_output: ČĆĐ. For some reason it keeps skipping 2 chars Š and Ž. If I try to insert or update data the values are show correctly. What could be the cause of such a problem?
Best regards,
Igor

How to read Image data from oracle DB?

How to read a oracle database object ORDSYS.ORDImage from oracle
database?
I can get a oracle.sql.STRUCT object from the database, but i can not
find the way to convert data to a image object(like oracle.ord.im.OrdImage)
I had used "OrdImage imgObjj1 =
(OrdImage)rs.getCustomDatum(1, OrdImage.getFactory());"
it's a example from oralce.
But OracleResultSet.getCustomDatum() method is already deprecated,
i can't find a new method to instead of it.
Who can help me ? Thank you!
[email protected]

More than likely, this is the interface you will use:
java.sql.Blob
http://java.sun.com/j2se/1.4/docs/api/java/sql/Blob.html
Once you get the blob, construct a Raster objects from the Bytes you receive from the blob. Then you can create an Image, ImageIcon, BufferedImage, whatever with the Raster object.
Good luck!

Error when reading BLOB field from Oracle usin Toplink

We experience a very annoying problem when trying to read a BLOB

exception stack trace that is reported to the console. As far as I can
judge a fault at oracle.sql.LobPlsqlUtil.plsql_length() happens first and
then at TOPLink.Private.DatabaseAccess.DatabasePlatform.convertObject().
The exception is permanently repeating that is very critical for us.

I have started the application with Oracle JDBC logging on and found that the problem may originate in a possible lack of syncronization in the pooled connection implementation:
DRVR FUNC OracleConnection.isClosed() returned false
DRVR OPER OracleConnection.close()
DRVR FUNC OracleConnection.prepareCall(sql)
DRVR DBG1 SQL: "begin ? := dbms_lob.getLength (?); end;"
DRVR FUNC DBError.throwSqlException(errNum=73, obj=null)
DRVR FUNC DBError.findMessage(errNum=73, obj=null)
DRVR FUNC DBError.throwSqlException(reason="Logical handle no longer valid",
SQLState=null, vendorCode=17073)
DRVR OPER OracleConnection.close()
so the prepareCall() is issued against an already closed connection and the
call fails.
I assume we have been using a JDBC 2.0 compliant driver. We tried out
drivers that Oracle supplies for 8.1.6, 8.1.7 versions. To be true I
couldn't find any information about the JDBC specification they conform to. Does it
mean that these drivers may not be 100%-compatible with JDBC 2.0 Spec?
How can I find out if they are 2.0 compliant?
Also I have downloaded Oracle 9.2.0.1 JDBC drivers. This seemed to work
fine until we found another incompatibility which made us return back to
8.1.7 driver:
UnitOfWork(7818028)--Connection(4434104)--INSERT INTO STATUSHISTORY (CHANGEDATE, FK_SET_STATUS_ID) VALUES ({ts '2002-10-17 16:46:54.529'}, 2)

Hello Yury,
I believe the problem is that TopLink's ServerSession by default executes read queries concurrently on the same connection. It does this to reduce the number of required connections for the read connection pool. Normally this is a good concurrency optimization, however some JDBC drivers have issues when this is done. I had thought that with Oracle JDBC 8.1.7 this issue no longer occurred, but perhaps it is only after version 9. I believe that the errors were only with the thin JDBC driver, not the OCI, so using the OCI driver should also resolve the problem. Using RAW instead of BLOB would also work.
You can configure TopLink to resolve this problem through using exclusive read connection pooling.
Example:
serverSession.useExclusiveReadConnectionPool(int minNumerOfConnections, int maxNumerOfConnections);
This will ensure that TopLink does not to try to concurrently execute read queries on the same connection.
I'm not exactly sure what your second problem with the 9.x JDBC drivers is. From the SQL and stack trace it would seem that the driver does not like the JDBC timestamp syntax. You can have TopLink print timestamp in Oracle's native SQL format to resolve this problem.
Example:
serverSessoin.getLogin().useNativeSQL();
Make sure you configure your server session before you login, or if using the TopLink Session Manager perform the customizations through a SessionEventListener-preLogin event.

Well, here is a very basic example of a PL/SQL pipelined table function that wraps a POP3 mail account into a SQL table - allowing you to run SQLs directly against the e-mail account.

PS. Oh yes - I defined a timeout exception and tried catching that to determine the eof for the message body, but ran into what seems to be an Oracle bug. However, simply checking whether there is data to read, using the UTL_TCP.Available() function, works great.

Read IMAP server from Oracle PL/SQL

Hi,
Is it possible to read emails (either through IMAP) and save those email (with attachments) into oracle tables through pl/sql?
I have a requirement of reading mailbox every 1 min and save new mails into database.
My Environment: Database 10g.

This may help you.

Reading Japanese characters from a JSP/HTML form.

I have a JSP/STRUTS/WEBLOGIC/ORACLE setup. I am able to get Japanese characters in database to be shown on the screen ( html ). However the users now want to enter Japanese characters on the screen and want to save these unicode characters in DB. How should I go about it?
I am using html:text tag for the input fields in the JSP. No matter what I try I am getting invalid characters..Thanks in advance.

hi debo_nair,
if i am not mistaken the japanese characters might be getting stored in the database as '?????' and other junk characters....
well I used the following technique:
1.retrieve the string from the text field and
2.convert it using the following method...
new String getbytes("the string entered in the text field","ISO-8859")
3.Next , store the string in the database
the syntax may be incorrect but just refer to any java book to get the correct syntax

Reading XML Files from oracle 9i or in Oracle 10g

Hi all,
Can any body suggest how to write a stored procedure to read XML file content and insert into a table.
Thanking you in Advance

I know I am blasphemous, but ....
We had a similar requirement: one file, each line was a "simple" xml doc corresponding to one db table record. The keyword here is "simple". We looked at the xml stuff, but decided that the easiest, best runtime performance, most extensible, easiest to maintain was:
use (sed|awk|perl) to convert xml to a flat file of fields, and then load the file with SQL*Loader. After all, loading flat files with many records is a job for SQL*Loader.
caveat: the xml in question was very simple and the same for all records:
timestamp|<log><id>1</id><ns>ns1</ns><prod/><cmd>order</cmd><result>ok</result><time>1813></time></log>

Read from Oracle DB and Write to MySQL

Hi All,
I am fairly new to database administration, so please bear with me if this is something that is simple or not achievable at all -
SetUp:
I have an Oracle DB on one dedicated Server, to which I only have a read_only access.
I have a MySQL database setup on a windows server 2008, both are on the company network and accessible to internal employees only.
Problem Statement:
I need to read certain tables from Oracle DB and push the records to MySQL database.
I have a stored procedure which was doing this but from one Oracle Schema to another, which is running fine, now I need to use the same stored procedure but read from one database (Oracle) and write to another database (MySQL), is there a way to do this through the stored procedure, I know I can write a java program to do this, but need to do it through a stored procedure.
Appreciate any help in this regards.

ThrowNew() with Japanese chars went wrong

Hi All.
I want to throw exception that has Japanese chars from C++ code.
char szMsg[256];
// put Japanese chars into szMsg.
// ... and throw exception.

How can I get a readable string from C++?
Thank you.

Thank you for your reply.
But I'm not familiar with C++, could you tell me in detail?
My project is compiled with _MBCS option, and I tried to convert string to UNICODE to get readable string in JNI by using

const char* szErrMsg = "...."; // including Japanese character
WCHAR szUnicodeMsg[256];
MultiByteToWideChar(GetACP(), 0, szErrMsg, -1, szUnicodeMsg,

mbstowcs(szUnicodeMsg, szErrMsg, strlen(szErrMsg)+1);
env->ThrowNew(ExceptionCls, (const char*)szUnicodeMsg);
(3) T2CW() macro
env->ThrowNew(ExceptionCls, (const char*)T2CW(szErrMsg));
Result
In case (1), unexpected string (like "B0D0F0H0J0?0") was displayed.
(by calling Throwable#getMessage() in JNI)
In case (2), only '?' was displayed in JNI.
In case (3), I got the same result as case (1).
Do you mean another way?
Thank you.

Read Tif Image from Database Display in Windows Fax Viewer

Code for reading a BLOB from Oracle which is a TIF image and displaying it in Windows Picture and Fax Viewer. Gives the ability to display with perfect resolution, Zoom In & Out, Rotate and Print.
I m storing the image on my C drive, you can store where ever you want.
package com.test.examples;
import java.io.File;
import java.io.FileOutputStream;

Let me know if you find some thing wrong in here.

REad all the file paths from DB in e.g. List<String>. Define javax.swing.Timer.
How to use timer read here
http://leepoint.net/notes-java/other/10time/20timer.html
or
http://docs.oracle.com/javase/tutorial/uiswing/misc/timer.html
When the timer's actionPerformed happens use next index in the array to get next filePath and show your image. When end of list is achieved just stop the timer (or startd from the beginning of the list again).

WebUtil Using Client_Text_IO with Japanese chars

Hi, I am trying to use Client_Text_IO to read text file with Japanese characters in it. But it seems like Client_Text_IO can't read Japanese chars properly. Can anyone tell me how to use Client_Text_IO with double byte
chars like Japanese?
Thanks in advance for any help.
Tad Teramoto

Hi Frank,
Thank you for your reply. Could you be a bit more specific about what this bug 3075927 really is? Is this a problem only in handling files with muli-byte chars or does it have an effect on other functions? And is there any workaround for it?
Thanks
