Storing and query japanese chars

I am storing japanese characters in a nvarchar2 column and the NLS_CHARACTERSET is UTF8. How do I insert japanese chars thru sqlplus and then query the same to confirm that they are getting stored ?

If you have access to GUI tools like iSQL*Plus or SQL Developer, try those instead of character based SQL*Plus. The GUI tools can display UTF-8 characters using proportional fonts, which support a wider number of UTF-8 characters than monospace fonts. They also allow you to enter Japanese characters in your INSERT statements simply by using your keyboard or clipboard.

Guide in Storing and querying Farsi characters./data

Hi All,
This is my first time in globalizing an application(in coldfusion). What I'm trying to do now is do some testing by creating a table, TEST_TABLE, with two columns, NAME and BIRTHDATE. I am using windows and my locale in windows is now set to Farsi. I am using Oracle 9i in UTF-8. Since Oracle9i doesn't support Farsi at this time(please correct me if I'm wrong), I set the nls_language to "Arabic" and the NLS_CALENDAR to "Persian". But still I wanna store/retrieve data in Farsi. Are my settings for Oracle correct? Any more suggestions to achieve this purpose? Any help is greatly appreciated. Thanks.

Yes, I already did that. I made some tests and they're fine. Although some still need some tweaking. Anyway, I just started this thread so as to have some tips/guidelines in doing the application. Maybe there are some things that I do not know yet that I can learn from all of you. Thanks.

Japanese chars display in Solaris 8

I have a sun box with solaris 8 and Windows NT. I had FTP a notepad file containing japanese text from windows NT to the Solaris Environment but whenever the file is opened in solaris using editors like vi or dtpad, some special characters appear in place of japanese chars. I have also tried :-
-- FTP the file in binary form from windows to solaris
-- Changing the "locale" value to ja_JP.UTF8
-- Changing the language option to en_US.UTF8 at the login screen.
But the problem still persists. Kindly help me out.

UTF8 will make your head melt.
setenv LANG ja_JP.eucJP
sjtoeuc FILE
(I use mutt in japanese on solaris all the time and most of my mail is in japanese ^^;;)

FILE_DATASTORE and non-ASCII chars

I have created an interMedia Text index
with the FILE_DATASTORE option, so that
interMedia treats table entries as
filenames and indexes the corresponding
file on the servers's filesystem.
But whenever the filename contains characters
which are not part of the US7ASCII charset (like dv| _), the file is not found. But both Oracle and the operating system support these characters.
The Oracle instance uses UTF8 as internal
characterset. The client which stores
the filenames in the table uses the
WE8ISO8859P1 charset. The values in the
database table are stored and shown correctly
when viewed with Oracle or Java client
programs.
So where does the charset conversion fail ?
The names are stored correctly, they can be
read correctly by clients, but the indexer
seems to use a wrong charset to translate
the filenames stored in the database into
filenames of the operating system.
Do I have to apply some additonal configurations to my indexer ?
Greetings,

I bump Dr. Chucks thread for a similiar problem with non-ascii chars.
The chars show up but the sorting is a bit off.
Example: A, Å, B, ... Z
Should be: A, B, ... Z, Å, Ä, Ö
In Swedish Å (the letter Aring;) is one of the last letters and should not be placed after A despite being similiar.
Any ideas?

Lookup-table and query-database do not use global transaction

Hi,
following problem:
DbAdapter inserts data into DB (i.e. an invoice).
Process takes part in global transaction.
After the insert there is a transformation which uses query-database and / or lookup-table.
It seems these XPath / XSLT functions are NOT taking part in the transaction and so we can not access information from the current db transaction.
I know workarounds like using DbAdapter for every query needed, etc. but this will cost a lot of time to change.
Is there any way to share transaction in both DbAdapter insert AND lookup-table and query-database?
Thanks, Best Regards,
Martin

One dba contacted me and made this statement:
Import & export utilities are not independent from characterset. All
user data in text related datatypes is exported using the character set
of the source database. If the character sets of the source and target
databases do not match a single conversion is performed.So far, that does not appear to be correct.
nls_characterset = AL32UTF8
nls_nchar_characterset = UTF8
Running on Windows.
EXP produces a backup in WE8MSWIN1252.
I found that if I change the setting of the NLS_LANG registry setting for my oracle home, the exp utility exports to that character set.
I changed the nls_lang
from AMERICAN_AMERICA.WE8MSWIN1252
to AMERICAN_AMERICA.UTF8
Unfortunately , the export isn't working right, although it did change character sets.
I get a warning on a possible character set conversion issue from AL32UTF8 to UTF8.
Plus, I get an EXP_00056 Oracle error 932 encountered
ORA-00932: inconsistent datatypes: expected BLOB, CLOB, get CHAR.
EXP-00000: export terminated unsuccessfully.
The schema I'm exporting with has exactly one procedure in it. Nothing else.
I guess getting a new error message is progress. :)
Still can't store multi-lingual characters in data tables.

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.

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

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.

Query generator and query wizard

with the help of query generator and query wizard, we create queries.
one of the application of generating query is that we can use it in formated search.
can plz anyone tell me what are the other possible application of queries created by guery generator and query wizard.
I am peruing training of SAP B1, so if any mistake is done from my side, I am sorry for that.
Thanks in advance.

Hi Punam.......
Query Generator is purely used for reporting as it uses SQL which is a strong tool of reporting. Moreover you can use the query generator for Formatted Searches as well as its SQL queries may useful in creating SP Transactions Notifications, Stored Procedures, Functions, Triggers etc.....

Assuming that you can already type and display Japanese characters on your platform. In terms of db storage, you need to create a database using a character set that can stored Japanese characters such as JA16SJIS, JA16EUC, UTF8, AL32UTF8 etc. Next you need to set your NLS_LANG to the character set on your client platform, so that Oracle can convert between the client and database character sets.
Check out the FAQ on the Globalization Support OTN web site for more info. http://technet.oracle.com/products/oracle8i/htdocs/faq_combined.htm

Difference between nvarchar2( 10) and varchar2( 10 char)

Hi ,
I had to enhance my application's DB to support unicode data entries(Multilingual data entries) and retrieval. I want to know the basic difference between the following data type decalrations:
nvarchar2( 10) and varchar2( 10 char)
Can any one suggest me which would be a optimum choice?

Yes, you are almost correct.
Can you read Japanese Character ? (There is no need to understand Japanese words meanings).
Are you ready? Let's go!

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.
env->ThrowNew(exceptionClass, (const char*)szMsg);
Then, in Java code, it is displayed with unreadable characters like "????".
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
(1) MultiByteToWideChar(...)
const char* szErrMsg = "...."; // including Japanese character
WCHAR szUnicodeMsg[256];
MultiByteToWideChar(GetACP(), 0, szErrMsg, -1, szUnicodeMsg,
sizeof(szUnicodeMsg)/sizeof(wchar_t));
env->ThrowNew(ExceptionCls, (const char*)szUnicodeMsg);
(2) mbstowcs(...)
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.
