Unicode in OCI

I know how to retrieve column text values in UCS2 charset, and i need to retrieve error text in this charset also. Somebody know, how to do this ? (This is actually in multi-tier applications. When clients uses different languages and codepages, it is good idea to use unicode in middle-tier)

In 9i you can retrieve the error message in
Unicode, earlier releases do not support
it.

OBIEE not working-plz help me

Hi My name is Priya
I installed OBIEE 10.1.3.4.2 sucessfully on windows 7 ultimate OS and database Oracle 11g R2 11.2.0.1.0
but when I tried to Import SH schema from OBIEE Admin Tool the SH schema is not appearing in the select data source under connection type ODBC 3.5.
I can see only DSN:Analyticsweb and Driver:Oracle BI server in select datasource under ODBC 3.5.
and even I cannot see the SH schema under any connection types(ODBC 2.0,DB2 CLI(unicode),XML,OCI 10g/11g.
but when I checked System DSN in ODBC Data Source Administrator even the SH schema was added as (Name:SH Driver:Oracle in OraDb11g_home1).
everything looks ok,but still I dont understand why SH schema is not appearing when am trying to Import it from Database in Oracle BI Administration.
Please help me I tried everywhere but no one is able to resolve my issue.
even you can email your responses at [email protected]
waiting for your replies with eager

Hi,
Thanks for your reply I really appreciate it.
I checked in SQL with the query select table_name from all_tables where owner='SH';
but it came with has no rows selected message
and also I tried to download the schema from the link which you have sent(http://gerardnico.com/wiki/database/oracle/sample_schemas)
but when I clicked the link it took me to Oracle Database - Sample Schemas and there under SH I clicked on ■Installation of the Oracle® Database Sample Schemas
but when I clicked on that the page says Http 400 bad request and the webpage cannot be found.
and also I clicked ■Oracle® Database Sample Schemas under reference,here also the page says samething.
and also I downloaded SH.zip under OBIEE,but here once I open the SH folder and opened sh in this folder 'SH' directly Oracle BI Administration tool is opening.
In this tool I can see the SH schema under presentation,Buisness model & mapping,Physical layers,but again when I start the OBIEE Administration tool under Oracle Business Intelligence from All programs and trying to import from database the SH is not appearing under ODBC 3.5 in select datasource.
I dont understand where Iam going wrong,please help me.

Don't give up just because there are other options out there.
Adobe is only giving up the free tool for education purposes, or unemployed developer. You didn't say if you were one of those.
I believe over time there will be plenty of room for alternate IDE approaches that support the Flex Framework; and in fact there are quite a few options already out there.

How to send Unicode to Oracle

Hello,
We have an intranet application that is live for sometime now. Our new requirement is to be able to store and view Japanese characters in some of the fields.
We have Oracle 9.2.0.5 with NLS_CHARSET as UTF8. Our application server is WebLogic6.1sp6 on Solaris v5.8 64 bit.
We use both thin driver (classes12.jar) and WebLogic 6.1 provided OCI thin driver, on different places of our application. The database column intended to store Japanese characters is just a VARCHAR and not NCHAR.
I'm copying some Japanese characters from various websites and trying to input them in my application through browser. We are able to store Japanese characters, but they are occupying upto 8 bytes per character. Actually Unicode databases only should take upto 3 bytes per character. My requirement is to be able to store upto 1300 Japanese characters in a VARCHAR2(4000) field. Currently, it is only storing about 500 Japanese characters. When trying to store more than this, it is throwing a "java.sql.SQLException: Inserted value too large for column".
I have already consulted Oracle and the reply I got is that it is not Oracle problem as the application needs to be changed so that it feeds physical UTF8 codepoints to Oracle. On their suggestion, I used iSQLPlus interface and was able to store 1300 Japanese characters in the database, by issuing an update statement. But the same data when seen from iSQLPlus is showing characters as follows: "& # 31258 ; & # 21481 ; & # 27470 ; & # 34507 ;" (I have added blanks so that your browser does not render it in Japanese). Hence they concluded that our application is NOT using UTF8 codpoints but a HTML based representation system using the ""& #" and then the unicode identifier for that character. For Oracle this is NOT a character, It's a string of 8 characters and hence it occupies 8 bytes. Please help me on how to feed UTF8 codepoints to Oracle?
I have already tried putting NLS_LANG=AMERICAN_AMERICA.UTF8 in my WebLogic startup script. I also tried putting
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> in my JSP's. (This actually makes the problem even worse that it displays junk instead of Japanese while retrieving).
Are there any other special settings that I need to be able to store Unicode characters? Please help.
Thanks
Varma
[email protected]

thanks the following steps did the trick
1. I put the following info in weblogic.xml
<charset-params>
<input-charset>
<resource-path>/*</resource-path>
<java-charset-name>UTF8</java-charset-name>
</input-charset>
</charset-params>
2. I added the weblogic.codeset=UTF8 for the WebLogic Oracle OCI connection pool
3. I added the nls_charset12.zip in the CLASSPATH for the Oracle thin driver that I'm using.
4. Added the <%@ page contentType="text/html; charset=utf-8"%> (Somehow the <jsp-param><encoding> tag does not work in weblogic.xml)

BUG: retrieving NCHAR value using ViewObject returns "???" with OCI driver

Hi,
after upgrading JDeveloper to 10.1.3.1 we cannot use OCI JDBC drivers, because they don't work correctly - characters, that do not exist in database character set (EE8ISO8859P2 in our case) are converted to "?". Thin driver works well. We need to use OCI, because we had some issues with RAC with thin driver.
Test case is easy: create table with NCHAR column, populate with unicode data, create ViewObject to select from this table and it will work only with THIN and not with OCI driver. This worked well with 10.1.3.0. When I tried to directly connect to DB and select that table using java.sql.Statement, it worked with both drivers, that's why I suspect the mechanics inside ADF BC.
I logged a SR for this in Metalink, but try this way as well, for someone else could hit the same problem.
Thanks for any help,
Viliam

Unicode in php oracle

While using multilanguage in php/oracle iam facing some issues
i gave input as : Portuguese: O próximo vôo à
and got output as : Portuguese: O pr?ximo v?o ?
for some special characters it is replaced by '?' mark.
iam using php5 and orcle 9 and OCI for connecting.
i gave NLS_CHARACTERSET as UTF8
and the unicode datatype as NVARCHAR2(100)
Plz some one help me out in solving it

To Determine Unicode Datatype encoding

Hi,
Going through the Oracle documentation found that Oracle Unicode datatype (NCHAR or NVARCHAR2) supports AL16UTF16 and UTF8 Unicode encodings.
Is there a way to determine which encoding is being used by Oracle Unicode datatypes thorugh OCI interface?
Thanks,
Sachin

That's a rather hard problem. You would, realistically, either have to make a bunch of simplifying assumptions based on the data or you would want to buy a commercial tool that does character set detection.
There are a number of different ways to encode Unicode (UTF-8, UTF-16, UTF-32, USC-2, etc.) and a number of different versions of the Unicode standard. UTF-8 is one of the more common ways to encode Unicode. But it is popular precisely because the first 127 characters (which is the majority of what you'd find in English text) are encoded identically to 7-bit ASCII. Depending on the size and contents of the document, it may not be possible to determine whether the data is encoded in 7-bit ASCII, UTF-8, or one of the various single-byte character sets that are built off of 7-bit ASCII (ISO 8859-15, Windows-1252, ISO 8859-1, etc).
Depending on how many different character sets you are trying to distinguish between, you'd have to look for binary values that are valid in one character set and not in another.

Migration key w/ unicode conversion only

hello - i'm doing a unicode conversion of a NW04 system, following the Unicode conversion guide point by point for the proces.
source: nw04 / ora10202 / hpux ia64 (non-unicode)
target: nw04 / ora10202 / hpux ia64 (unicode)
the import is failing bc it says the migration key is not good. the guide didn't even mention the need for the key and i was not expecting to have to use one since the OS/DB remain the same on the target system. any ideas?

from the MIGKEY.log file -
/sapmnt/LH7/exe/R3load: sccsid @(#) $Id: //bas/640_REL/src/R3ld/R3load/R3ldmain.c#6 $ SAP

Hi Ben,
This looks more like a Oracle Error and not a Migration key related error.
I think its TNS Related, please check the following URL:

Unicode app on Win32 platform: What should the client locale be?

You probably have solved one of my biggest mystery when you say there is no UTF8 Win32 codepage. I am using Windows 2000 with Oracle 8i OCI. I used Win32 API putenv() to set NLSCHARACTERSET to UTF8 in my Unicode-16 application. However, all the accented character insertions from my application, such as @, have been corrupted when they get through the OCI calls.
What client locale should I set to? My app is supposed to support Oracle Server with character set WE8ISO8859P1, UTF8, JA16EUC and JA16SJIS. Originally I thought setting my app to NLS_CHARACTERSET to UTF8 would solve all the encoding and transcoding problem. Please advise. Thank you!
Regards, Nancy.

Hi Nancy,
I need a few clarifications. You mentioned your app is supposed to support Oracle Server with character set
WE8ISO8859P1, UTF8, JA16EUC and JA16SJIS. Are you saying that the database character set might be any of 4 you list? Is your app 3 tier? Can a web browser call it? More details would be appreciated, and I will do my best to help. I would like you to take a look at a particular paper: "Migrating Oracle Internet Applications to Support Unicode" at
http://technet.oracle.com/products/oracle8i/
There are specific sections on OCI programming that I think fit your scenario. Take a look around page 30.

OCI, 64-bit and C++ in Oracle 8.1.7?

Hi,
In the provided demo makefile (demo_rdbms.mk) for OCI on
Oracle 8.1.7 a comment says:
# 64-bit OCI programs in C are supported but
# 64-bit external procedures and 64-bit OCI programs in C++ are
# NOT supported.
Will NOTHING work or are some functionality possible?
I want to mix ProC/C++ with OCI with the use of sql2oci
in a single threaded C++ application.
(More specific I want to use direct path streams).
Any suggestions?

The National Character Set in 8i was only meant to support a few special Asian character sets. Though it is set to whatever you set the database to the NCHAR columns will not work properly for UTF8. You will need to use SQL CHAR fields in order to support UTF8 in 8i. And the semantics are byte. In Oracle9i the National Character Set exclusively supports Unicode via the character sets UTF8 and Al16UTF16. The default is Al16UTF16 which is UTF-16. The 9i NCHAR fields are character semantics so field(5) would be 5 characters not bytes. There are a couple of papers on our home page that talk about unicode support at:

Unicode i/o with OCI9

Hi,
Win2k OS
I am trying to build an appln in VC using OCI9 so as to work with unicode data(Devnagari-Hindi).
Case I :
Client : oracle815 (NLS_LANG=UTF8)
server : oracle815 (NLS_NCHAR_CHARACTERSET=UTf8)
If i w'd use NCHAR sql datatypes to work with unicode data, then i can successfully insert/retrieve hindi data into/from Oracle815 DB. (e.g. a Hindi char with hex code 05 09 is inserted as e0 a4 85 in Database and retrieved as e0 a5 85 which u need to convert it back to unicode using multibytetowidechar())
Case II :
Client : oracle815 or 912 (NLS_LANG=UTF8)
server : oracle912 (NLS_NCHAR_CHARACTERSET=UTf8)
In this case(ora815 client), If i w'd follow the same operation as in case I, then i dont get proper result after fetch. (e.g. a Hindi char with hex code '05 09' is inserted as 'e0 a4 85' in Database, BUT it is not retrieved back as 'e0 a5 85', but as '60 24 05'.
And if i w'd use ora912 client, then i get the result as '3F' for the same above character.
What's wrong in my program or settings.?
Plus, my another requirement is, i dont want to change NLS_LANG parameter in registry manually, but, i w'd like change it programmaticaly thru OCI. For this, i tried using OCI funct OCIEnvNlsCreate(..., csid, ncsid). I set the last two parameters to OCI_UTF16ID(The header oci.h has the only constant OCI_UTF16ID defined !. We cant use any other charsetID like UTF8 or what ?), then, i get an error 'ORA-12154: TNS: Could not resolve service name'.
What am i missing here.?
TIA,
regards,
Virupaksh

Character Unicode Value

Is it possible to have a VB script return the unicode values for a given range of characters in a paragraph or story?

We tried it on a 8.1.7 database and I was not able to reproduce
the error.
Here is how I insert and retrieve the data:
OraclePreparedStatement ps =
(OraclePreparedStatement) conn.prepareStatement
("insert into tab01 values (?)");
ps.setString(1, "\u2018");
ps.executeUpdate();
ps.close();
ResultSet rs = (conn.createStatement()).executeQuery("select col01
from tab01");
while(rs.next())
String str = rs.getString(1);
System.out.println("COL01 is "+str);
showUnicode("COL01 (Unicode Value) is "+str);
(conn.createStatement()).close();
conn.close();
And here is the result from the database:
SQL> select dump(col01, 16) from tab01;
DUMP(COL01,16)
Typ=1 Len=3: e2,80,98
Are you using thin driver or oci driver?
If oci driver is used, NLS_LANG needs to be set correctly and
the Client OS code page must support these characters. Hope this
helps.

Error while creating a report that uses Oracle OCI JDBC connectivity

Please let me know why my CR and LF characters are removed from my forum posting *****
Hi,
I was trying to create a report that uses Oracle OCI JDBC connectivity. I am using Eclipse3.4 download from "cr4e-all-in-one-win_2.0.2.zip". I have successfully created a JDBC OCI connection.
The connection parameters are given below:
URL: jdbc:oracle:oci8:@xe
Database: xe
username: <userName>
password: <password>
I have tested the above connection in Data source Explorer and it works fine!!!
But I am getting the following error when I drag-and-drop a table from the list of tables. Not sure what I am missing here? Any help is highly appreciated.

Hi Ted,
Thanks for the feedback. I was able to create a report in Creystal Reports Designer 2008 using OCI. It is not allowing only in the Eclipse plugin. In our environment we are not allowed to user Oracle thin connections and ONLY OCI is allowed.
1) Can you please let me know if there is a way to do this?
2) Will it allow data sources using native database driver?
3) If so, can I use JRC to create these reports from a desktop java program?
Thanks & Regards
Karthik
