How to handle national character set datatypes in oracle?
Hi
Can anyone tell me how to handle national character set datatypes in oracle?
Thanks in advance
And for data manipulation, append "N" the literal values being used in the command.
The "N" indicates that the string is to be treated as Unicode Text.
For Example: insert into TableName (ColumnName) values (N'ValueToBeInserted');

IMP-00069: Could not convert to environment national character set's handle

nullHi James,
IMP-69 can occur if you try to use an EARLIER version of IMPORT against an export (.dmp) file produced by a LATER version of EXPORT.
How about trying this:
Use the 8.1.5 EXPORT utility from Win2K to connect to your Solaris 8.1.7 database; then use the 8.1.5 IMPORT utility to import the file into the 8.1.5 W2K database.

Hi,
on 10g, on Win 2003, how to verify if database is NATIONAL CHARACTER SET UTF8 ?
Thank you.SELECT *
FROM v$nls_parameterswill show you all the NLS parameters. You're presumably looking for the row where parameter = 'NLS_NCHAR_CHARACTERSET' though there may be a few more parameters that you're interested in.

Fixed & variable width national character set
In its discussion of NCHAR and NVARHCAR2 datatypes, Oracle talks about fixed width and variable width database character sets. What are they?
I think the concept of fixed length (i.e. NCHAR) and variable length(i.e. NVARCHAR2) types is a different thing. That I understand.
From Oracle doc:
'If the national character set of the database is fixed width, such as JA16EUCFIXED, then you declare the NCHAR column size as the number of characters desired for the string length. If the national character set is variable width, such as JA16SJIS, you declare the column size in bytes.'
nullFixed width charactersets are those in which each character is defined by a fixed number of bits, say 7 or 8 or 16
Variable width charactersets are those for which either 7 or 8 or 16 bits are used to save space. Let us say a character needs only 7 bits, then only 7 bits will be used in this case, and if another character needs 16 bits, they will be used.
In fixed width all characters have same number of bits, so it has higher space requirement.
These have nothing to do with char and varchar2 data types..... -

How to change the character set?
Platform is win2000 and oracle 8.17. I need to write data in Bulragian. Automatic character converter in oracle didn't work! Database is created already!
Is there any function in pl/sql or Java that can convert character set in cl8mswin1251? When I read the data from database there are only ?????
Thank you in advance!I'm not sure what you're asking here. "Will it be ok" for what?
Assuming
- you read the chapter I linked to,
- ran the character set scanner,
- the character set scanner indicated that all your existing data is properly encoded ISO 8859-1
- the character set scanner indicated that all the ISO 8859-1 data could be converted to Windows-1252
- all the national character set data was properly encoded in whatever national character set the database had
- you did the export properly
- you did the import properly
- your client NLS_LANG settings are all correct
then sure, everything should be OK.
If you skipped one of these steps, I would again strongly encourage you to read the chapter I linked to originally as well as the Metalink article others have pointed you to.

How to change the Character Set from AL32UTF8 to WE8DEC
Hello!!
I want to know how to change the character set in the database from AL32UTF8 to WE8DEC.
I tried to use the comand ALTER DATABASE CHARACTER SET but I got an error because WE8DEC is not a superset of AL32UTF8.
I need to import tables from a server that uses WE8DEC. So when I do the import to my server, wich has AL32UTF8 , I can't import the rows that include an Ñ.
So I want to change the caracter set to WE8DEC. How can I do it?
Is it needed to change the language configuration? The remote server has AMERICAN_AMERICA, and my server has MEXICAN SPANISH_MEXICO (both uses text in spanish).
Thanks a lot!!When you export from WE8DEC server what did you use
for NLS_LANG char set? And when importing?
The export was done in another computer because I can't do the export in the server (I have 10g, and the remote server has 9i and the export is not working). In my server, when I tried to do the import, the NS_LANG value was MEXICAN SPANISH_MEXICO.WE8MSWIN1252.
When I try to import to my database I got the error:
import done in WE8DEC character set and AL16UTF16 NCHAR character set
import server uses AL32UTF8 character set (possible charset conversion)
export client uses WE8MSWIN1252 character set (possible charset conversion)

How to alter database character set from AL32UTF8 to EE8MSWIN1250
Hi folks,
I'm using an Oracle 10g, XE database, which has a database character set set to AL32UTF8, what causes that some characters like "č ť ř ..." are not displayed.
To fix this issue, I would like to change it to EE8MSWIN1250 character set as it's set on server.
Unfortunatelly below steps don;t work for me:
connect sys as sysdba;
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE NATIONAL CHARACTER SET EE8MSWIN1250;
ALTER DATABASE CHARACTER SET EE8MSWIN1250;
SHUTDOWN IMMEDIATE; -- or SHUTDOWN NORMAL;
STARTUP;Value in regedit: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_XE is set to CZECH_CZECH REPUBLIC.EE8MSWIN1250
I'm struggling with this issue for hours and unfortunatelly can't make it work. Any advise is more than welcome.
Thanks,
Tomas
I tried to use hints listed here , but always getting some ORA messages.Hi Sergiusz,
Thank you for your reply. You're right, I've probably didn't provide a full details about my issue, but at least now I know, that database encoding(characterset) is correct.
Here is my issue:
Within my APEX application I would like to use a JasperReportsIntegration, so to be able to create and run iReports straight from APEX application. Installation, and implementation of JasperReports works fine, I had no issue with it.
As a second step I've created a simple report using iReport tool, when if preview function is used, all static characters (from report labels) are displayed correctly. Database items are displayed incorectly - some Czech characters are not displayed. Language within report is set to cs_CS, but I've tried also other options. No sucess.
When I run that report from APEX application (from server) then the same issue - data from database are returned without some czech characters.
Kind regards,
Tomas -
How to handle large result set of a SQL query
Hi,
I have a question about how to handle large result set of a SQL query.
My query returns more than a million records. However, the Query Template has a "row count" parameter. If I don't specify it, it by default returns only 100 lines of records in the query result. If I specify it, then it's limited to a specific number.
Is there any way to get around of this row count issue? I don't want any restriction on the number of records returned by a query.
Thanks a lot!No human can manage that much data...in a grid, a chart, or a direct-connected link to the brain.
What you want to implement (much like other customers with similar requirements) is a drill-in and filtering model that helps the user identify and zoom in on data of relevance, not forcing them to scroll through thousands or millions of records.
You can also use a time-based paging model so that you only deal with a time "slice" at one request (e.g. an hour, day, etc...) and provide a scrolling window. This is commonly how large datasets are also dealt with in applications.
I would suggest describing your application in more detail, and we can offer design recommendations and ideas.

National character set in JSP report
Hi. National character set is not seen in JSP reports, while in paper reports all is OK. What's the problem?
Hi Volodia,
You can set the character set inside the JSP as:
<%@ page contentType="text/html;charset=ISO-8859-1" %>
Change the character set to "utf-8" or an appropriate value.
Alternatively, in the web browser also, you can change the encoding (View > Encoding > ...)
