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 change the character set of the D/b

    Hello All,
    When i issue the command
    ALTER DATABASE CHARACTER SET UTF8
    It gives me the error that I can only change the character set to a superset of the existing character set.
    Is there any way i can change the character set without recreating the database.
    TIA
    Naveen

    The existing character set is the basis for the new character set. This is fair enough, because the character set determines how the actual data is stored in the database. Allowing new characters is a minor change: completely re-encoding your entire database is not.
    I'm afraid export, recreate and import is your only option.
    Cheers, APC

  • How to change the character set encoding not being a superset one

    HI, i have a fresh installed database, but i realize the character set support in my client is not good enough, since its a not production database i want to change the character set encoding to anothor one not being a superset of the old one.
    I have tried the "ALTER DATABASE CHARACTER SET WE8MSWIN1252" but it fails claiming i need a superset one.
    I guess its just a single steps to do it, i have all the privileges, just not the time to reinstall and setup everything.

    Do you know what that does to the existing data, though? My hunch would be that any characters which have a different binary representation in the source & target character sets would be corrupted.

  • How to define the character set of an outbound EDI batch in BizTalk 2010?

    I have some EDIFACT files with a character set of UNOC though lowercase strings and umlaute should be allowed. These files should be batched in an outbound EDIFACT file. But the batching orchestration of the related send port throws some validation errors.
    If I convert the strings to uppercase characters everything's working fine. So it seems that the outbound batching orchestration uses the UNOA character set internally for the validation of the EDIFACT files...
    How can I change the character set of the outbound batching orchestration in BizTalk 2010? No settings found regarding the character set of outbound batching orchestration in the party and agreement configuration so far. Thank you

    Hi Philipp,
    To define a character set in EDIFACT,
    UNA segment is used. After defining see, How Validation of an EDI Interchange Is Configured and Outbound

  • Changing the character set in RoboHelp 7 file converted from 5

    The character set of the output files for WinHelp defaults to
    utf-8. How can the default be set to windows-1252 per project or
    for all projects in RoboHelp 7?

    This is related to the posting - "RoboHelp 7 (with patch) IE6
    does not display popup field definitions". Somewhere in our
    environment the character set is getting changed to western
    european (ISO) for the pages that do not load initially in IE6/XP
    from the OAS even though the code generated by RoboHelp is utf-8.
    The WebHelp generated in RoboHelp v5 has a characterset of
    windows-1252. None of the pages with the character set of
    windows-1252 have a problem loading (or changing the character
    set). The problem may be on the OAS or the single signon
    layer.

  • How to get the character set which i want it to be?

    i confront a problem, when using jdbc to connect to oracle8i database on solaris; because i use getBinaryStream() to read from db in "byte" reading, seemly it would use default character set on OS or database(such as EUC,etc.), not which the client i want it to be. is there anyway to take control of such code writing(i mean to change the character set when i get byte out of database, thus the byte would use NLS_LANG the same as using sqlplus setting in user env)?

    First of all read Note 581312 - Oracle database: licensing restrictions:
    As of point 3, it follows that direct access to the Oracle database is only allowed for tools from the areas of system administration and monitoring. If other software is used, the following actions, among other things, are therefore forbidden at database level:
    Creating database users
    Create database objects
    Querying/changing/creating data in the database
    Using ODBC or other SAP external access methods
    Are you trying this on the database server itself? If yes, then you need to install the hebrew codepages as well as hebrew fonts in order to display the data correctly.

  • Website not displaying correctly. Firefox is changing the character set to Western (ISO-8859-1) automatically.

    Normally I have set Firefox (or it's set by default) to Character Set Unicode (UTF-8) and everything displays perfectly. I've never had a problem before.
    Now however, whenever I upload my own website, for some bizarre reason on that particular tab (and only that tab) the Character Set is changed over to Western (ISO-8859-1) and then there's a few characters within my site that do not display correctly, namely apostrophes and hypens.
    It definitely isn't my software (Serif WebPlus X4) because the page displays correctly in every other browser. Plus it displays correctly in Firefox if I change the Character set back to Unicode.
    PS The site is a work in progress

    That happens because the server sends a content-type (<b>text/html; charset=ISO-8859-1</b>) via the HTTP response headers and in that case that content type prevails. The page code is saved with an UTF-8 byte order mark () that you see in this case.

    How to change the language setting in Adobe Flash CS6, from Chinese to English?

    Unless you have a multilanguage serial/ installer,  you are on Creative Cloud or care to run through language swap you can't. Retail serial numbers are language specific and most Adobe apps cannot be coerced or switched on the fly since without the proper language resources installed, this won't work...

    it will look like it is doing nothing but give it time and it will sign you in with the new username.
    is it possible you have multiple itunes accounts?
    when you changed your itunes account from your me.com to your gmail.com address did you change it within the itunes Edit Account Info ('Store' menu then select 'View My Account', then sign in , select edit account info) or did you just create another itunes account?

  • Precautions i need to take when changing the Character set

    Hi,
    ORACLE VERSION: 10G Release 1 (10.1.0.3.0)
    I am going to change my database's characterset from AL32UTF8 to WE8MSWIN1252 character set and AL16UTF16 NCHAR character set. So i have few questions for you.
    1. What is the difference between Character Set and National Character set? Do i have to set both?
    2. What are precautions that i need to take while changing the characterset?
    3. What are JOB_QUEUE_PROCESSES and AQ_TM_PROCESSES parameters in Plain English? Why do i have to set these parameters to 0 as mentioned in this post below.
    Storing Chinese in Oracle Database

    1) The database character set controls (and specifies) the character set of CHAR & VARCHAR2 columns. The national character set controls the character set of NCHAR & NVARCHAR2 columns.
    2) Please make sure that you read the section of the Globalization manual that discusses character set migration. In particular, going from UTF-8 to Windows-1252 is going to require a bit more work since the latter is a subset (and not a strict binary subset) of the former.

  • How to change Database character set?

    Hi,
    We are planning to make a clone of production Database which has:
    select value$ from sys.props$ where name='NLS_CHARACTERSET';
    AL32UTF8
    We have set up a new server for that purpose and installed database, but by default it has
    select value$ from sys.props$ where name='NLS_CHARACTERSET';
    WE8ISO8859P1
    So after making full import from full backup file we have some broken character in database.
    How can I change from WE8ISO8859P1 to AL32UTF8?
    I expect that I need to shutdown the clone database or even make from scratch full import.
    Thanks

    I made a full backup from production database which has AL32UTF8
    My new database is fresh and it has WE8ISO8859P1
    I think the reason why I'm having some corrupted characters is because of difference in Character set between two database, right?
    so I will need to change new database Character set to AL32UTF8 then make again full import.
