How to Insert Chinese characters in Japanese Database

Hi all,
I am having following characteristics on my computer
Machine OS --Windows Server 2003
OS language --Japanese
Oracle
Oracle9i Release 9.2.0.1.0 - Production
NLS_LANGUAGE JAPANESE
NLS_CHARACTERSET JA16SJIS
Now, i want to insert into database chinese characters. Please guide me how to do the following thing.
How to insert chinese characters on local machine and if i want to insert on the remote databse (i can not create database link for remote database). I have to send batch file or SQL file and they will execute it on their side.
if i use this command
alter session set nls_language = "SIMPLIFIED CHINESE"
and then insert the records and revert back to japanese character set. Is this correct way....?
Thanks in advance,
Pal

As dombrooks has pointed out, unless all the Chinese characters you are trying to store can be represented in the Shift-JIS character set, which seems unlikely, but I'm not an expert on East Asian languages and I believe there are some glyphs that are shared between various languages, then you're not going to be able to store this data in this database in CHAR or VARCHAR2 columns.
Depending on the national character set, you may be able to store the data in NCHAR/ NVARCHAR2 columns, though using these data types can substantially increase application complexities since various languages and libraries don't support NCHAR/ NVARCHAR2 columns or require you to jump through some hoops to use them. Your applications would also have to support both character sets, so your applications would all have to be Unicode enabled most likely, which is certainly possible but it may not be a trivial change.

Hi, Jenny,
When you said unable to insert to database, do you mean you get all ? marks in the database or garbage characters in the database?
? marks mean there are some byte chop off, and garbage characters mean the bytes are ok, just encoding problem.

How to insert chinese characters in a table use FDK?

Hello~~
I am expecting to insert chinese characters in an XML file's table.
I'm using FDK7.2, if i use:
F_ApiAddText(docId, &tRange.beg, "asdf");
The English letters "asdf" can be insert correctly in the right place,
But, if insert chinese characters like this:
F_ApiAddText(docId, &tRange.beg, "人们");
No characters insert.
How can i solve this problem?
Please advise
Thanks
zhaopeng

Zhaopeng,
Which encoding are you using for the Chinese characters? FrameMaker 7.2 does not support Unicode or UTF-8. I have not done this before, but I guess you need to supply the characters in Big5 resp. GBK encoding, see
http://help.adobe.com/en_US/FrameMaker/8.0/chinese_korean.pdf
[Ignore the 8.0 in the URL, the document talks about FrameMaker 7]
You also may have to make sure the paragraph format at your text location uses a Chinese font before inserting characters.

How to insert chinese or Japanese character into database

Hi,
Can any one please let me know how to insert chinese character to database.
We tried to insert some chinese character by copying but the characters are showing different while selecting from the database.
Should we install any font or something into database server for getting the character???

Hi,
If your NLS_NCHAR_CHARACTERSET is set as AL16UTF16, then you can create a table with datatype NCHAR or NVARCHAR in the same instance and will be able to store foreign characters provided your client termional is configured to enter chinese characters.

Issue of inserting greek characters into Oracle database using ICAN505

Hi All,
We are currently facing an issue of inserting greek characters into Oracle database using ICAN505.
We receive a file containing greek characters.The values from the file should be inserted into the database.We are reading the file using file OTD with default encoding.
The file can contain english characters too other than greek characters.
The database NLS_CHARACTERSET is AL32UTF8.
When I insert using an insert statement directly ,the values get inserted properly into the DB table.
Inserting the same values using code results in improper characters getting inserted into the table in the database.
Please help....
Thanks in advance !!

It works for SQL Developer, which does not depend on NLS_LANG, so I suspect a problem with your NLS settings.

Problem to insert Chinese Characters(GB3212) into MySQL

I met a problem to insert Chinese Characters (GB3212) into MySQL using Entity Bean (or JPA).
For example, when a hardcoded string "{color:#ff0000}电器me元件{color}" is inserted, it is displayed as "{color:#ff0000}??me??{color}" in MySQL.
The NamedQuery is also not working for Chinese Characters.
The setting are as following:
GlassFish JDBC connection pool: useUnicode=true, charecterEncoding=gb2312
NetBeans IDE: source encoding set to GB2312;
MySql table: the column set to CHARACTER SET gb2312;
Any experts, please give advice
Thanks lot

I didn't noticed that there is a {color:#ff0000}sun-resources.xml{color} file under {color:#ff0000}<ejb project>/server resources{color}.
This file has a pool configuration. This config just overwite the paremeter i added using Admin Console every time a client is lauched. So there are two option to fix this problem.
1. Insert the follwowing two lines into the {color:#ff0000}sun-resources.xml{color}
<property name="characterEncoding" value="gb2312"/>
<property name="useUnicode" value="true"/>
2. delete the everthing in the {color:#ff0000}sun-resources.xml, using Admin Console {color}config your own pool & DataSource
I tried first option & it works.

Insert chinese characters to mysql

I have searched the forum and found a useful links --http://forum.java.sun.com/thread.jspa?threadID=530358 about inserting chinese characters to mysql. However, I can't see the chinese characters displayed in the db. The charset and collation of my table are utf8 and utf8_bin respectively. Can anyone help me? Below is my source code
------------------ Servet ---------------------
package test;
import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class testServlet extends HttpServlet {
private Connection conn;
public void init(ServletConfig config) throws ServletException {
     sSysPhyPath = config.getServletContext().getRealPath("/");
public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException, ServletException
     // set content type and other response header fields first
     res.setContentType("text/html");
     // get the communication channel with the requesting client
PrintWriter out = res.getWriter();
out.println("<html>");
out.println("<body bgcolor=\"white\">");
out.println("<body>");
     req.setCharacterEncoding("UTF-8");
     sValue = req.getParameter("s1");
     out.println(sValue.getBytes("UTF-8") + "<br>");
     DBConnection objConn = new DBConnection(sSysPhyPath);
     try {
          conn = objConn.get();
          objConn.execQuery(conn, "insert into TBL_test (test_desc) values ('" + sValue.getBytes("UTF-8") + "')");
     catch(Exception e) {
          e.printStackTrace();
     objConn.closeConnection(conn);
out.println("</body></html>");

<body bgcolor="#666666">
<form name="test" method="post" action="testServlet">
<input type="text" name="s1">
<input type="Submit" name="Submit" value="Submit">
</form>
</body>
</html>
Besides, if I code the chinese characters directly in the servlet page, what is the encoding of the chinese characters by default? Is it related to my OS locale?
Thanks a lot.

objConn.execQuery(conn, "insert into TBL_test
st (test_desc) values ('" + sValue.getBytes("UTF-8")
+ "')");You would be better off using a PreparedStatement and parameters. This will let the MySQL JDBC driver take care of the required encoding.

Unable to insert Chinese characters in Database

My problem is that I am not able to insert chinese
(to traditional chinese) characters into my tables in the
database.
I have changed the character set to UTF8 while creating the
database and also tried the alter session command in SQL to
alter the NLS_LANGUAGE and NLS_TERRITORY (to say traditional chinese).
But this did not solve my problem.
Also tried all possibilites like getting Chinese characters
in my notepad by copy - paste from a Chinese web site
but while giving the insert into command in my database
it takes some junk values.
Someone PLEASE HELP!!!URGENT!!!
Thanks in advance.

You mentioned in your first note that you have set your database character set to UTF-8? If so, then you are able to store and retrieve multilingual data, including Chinese and Japanese characters. Your issue is not the database. Your client OS must be able to support these languages as well. It is likely that your version of OS supports only Latin and Western European characters. By the way changing your NT regional setting only effects sorting, date formats etc. It doesn't help you change the languages that your keyboard will support.
1.To determine your Win32 operating system's current ANSI CodePage (ACP). This can be found by bringing up the registry editor (Start --> Run..., type "regedit.exe", and click "OK") and looking at the
registry entry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage\ACP (there are many registry entries with very similar names, so please make sure that you are looking at the right place in the registry).
2.To find the character set in the table below based on the ACP you got above.
ANSI CodePage (ACP) Client character set (3rd part of NLS_LANG) (*1)
1250 EE8MSWIN1250
1251 CL8MSWIN1251
1252 WE8MSWIN1252
1253 EL8MSWIN1253
1254 TR8MSWIN1254
1255 IW8MSWIN1255
1256 AR8MSWIN1256
1257 BLT8MSWIN1257
1258 VN8MSWIN1258
874 TH8TISASCII
932 JA16SJIS
936 ZHS16GBK
949 KO16MSWIN949
950 ZHT16MSWIN950
others UTF8 (*2)
(*1) The character sets listed here are compatible with Win32's non-Unicode graphical user interface (GUI). Since Win32's MSDOS Box (Command Prompt) uses different character sets, NLS_LANG needs to be manually set in the MSDOS Box (or set in a batch script) in order to handle the difference
between Win32's GUI and MSDOS Box. (Please see "NLS_LANG Settings in MS-DOS Mode and Batch Mode" in the Oracle8i Installation Guide Release 2 (8.1.6) for Windows NT, part# A73010-01.)
(*2) If you use UTF8 for the 3rd part of NLS_LANG on Win32, client programs that you can use on this operating system would be limited to the ones that explicitly support this configuration. Recent versions of Oracle Forms' Client/Server mode (Fat-Client) on NT4.0 would be an example of such client
programs. This is because the user interface of Win32 is not UTF8, therefore the client programs have to perform explicit conversions between UTF8 (used in Oracle side) and UTF16 (used in Win32 side).

How does world_lexer index special characters in Japanese database?

Does any one have any information on how world_lexer indexes special characters (such as $, #,& -, _ etc.) in Japanese database?
Your help will be highly appreciated.

We worked this out via e-mail - the short answer for posterity is that the special characters are not added to the token list and printjoins is not an attribute for the world_lexer.
