PL/SQL Developer mudar para ANSI

[pyro]

Pessoal, estou utilizando o PL/SQL Developer da Allround e notei que todos os fontes (packages, functions, etc) que tenho aberto são visualizadas em UTF-8, como todos os fontes deste banco são ANSI os caracteres especiais ficam com "?".
Estou rodando para procurar identificar onde consigo configurar para forçar os fontes serem abertos e editados em ANSI, porém não encontrei, alguém já passou por isso e sabe onde ajustar?

Precisa setar a variável NLS_LANG.

Execute esta query:

Selecionar tudo

select value from nls_database_parameters where parameter='NLS_CHARACTERSET';

Esse é o charset que o banco ta configurado.
Aí este mesmo tem que ser configurado no Windows, no REGEDIT.

Aqui tem um link que pode ajudar:

Setting NLS_LANG Environment variable for Windows and Unix for Oracle Database
I am going to change the NLS_LANG value from English to Swedish as an example.

1. Determine the current NLS_LANG value in database

Selecionar tudo

SELECT * FROM V$NLS_PARAMETERS;

Selecionar tudo

Parameter                                 Value
--------------------------------------------------------------------------
NLS_LANGUAGE                          SWEDISH
NLS_TERRITORY                            SWEDEN
NLS_CURRENCY                            Kr
NLS_ISO_CURRENCY                 SWEDEN
NLS_NUMERIC_CHARACTERS    ,.
NLS_CALENDAR                           GREGORIAN
NLS_DATE_FORMAT                 RRRR-MM-DD
NLS_DATE_LANGUAGE           SWEDISH
NLS_CHARACTERSET                WE8MSWIN1252
NLS_SORT           SWEDISH
NLS_TIME_FORMAT                 HH24:MI:SSXFF
NLS_TIMESTAMP_FORMAT                  RRRR-MM-DD HH24:MI:SSXFF
NLS_TIME_TZ_FORMAT                         HH24:MI:SSXFF TZR
NLS_TIMESTAMP_TZ_FORMAT       RRRR-MM-DD HH24:MI:SSXFF TZR
NLS_DUAL_CURRENCY             €
NLS_NCHAR_CHARACTERSET               UTF8
NLS_COMP                                             BINARY
NLS_LENGTH_SEMANTICS                     BYTE
NLS_NCHAR_CONV_EXCP                      FALSE

Format of the NLS_LANG value is [NLS_LANGUAGE]_[NLS_TERRITORY].[NLS_CHARACTERSET]

In the above case value for NLS_LANG is SWEDISH_ SWEDEN. WE8MSWIN1252



2. Set NLS_LANG Value in client

a. Set NLS_LANG value in client (This is not permanent Solution, for permanent solution check 2.b)

Selecionar tudo

                  ALTER SESSION SET NLS_LANGUAGE = '<NLS_LANGUAGE>';
                  ALTER SESSION SET NLS_TERRITORY = '<NLS_TERRITORY>';

Example:

Selecionar tudo

                  ALTER SESSION SET NLS_LANGUAGE = 'SWEDISH';
                  ALTER SESSION SET NLS_TERRITORY = 'SWEDEN';

Check:

Selecionar tudo

            SELECT USERENV('LANG') FROM DUAL;
                         USERENV(‘LANG’)
                        ------------------------------
                         S

Selecionar tudo

SELECT * FROM V$NLS_PARAMETERS
where parameter in('NLS_LANGUAGE','NLS_TERRITORY');   

PARAMETER                   VALUE
--------------------------------------------------                                  
NLS_LANGUAGE SWEDISH
NLS_TERRITORY   SWEDEN       

b. Set NLS_LANG value in client (This is permanent Solution)

Windows:

i. Go to Start-> run
ii. Type regedit and click ok
iii. Drill Down to HKEY_LOCAL_MACHINE->SOFTWARE->ORACLE-> KEY_OraClientxxx_homeX (xxx is the oracle client version and X is the currently used home)
iv. Double click NLS_LANG and change Value data. For example in the example scenario updated NLS_LANG value to SWEDISH_SWEDEN.WE8MSWIN1252
v. Close regedit

Make sure you have backup windows registry before modifying it.

Or

i. Click on Computer, select Properties.
ii. Select Advance system settings
iii. In the Advance tab, select Environment Variables
iv. Select New
v. Set variable name NLS_LANG and variable value SWEDISH_SWEDEN.WE8MSWIN1252
vi. Select ok and you should now see the new environment variable that you just created.

Linux:

Selecionar tudo

 setenv NLS_LANG <NLS_LANG>

Example: setenv NLS_LANG SWEDISH_SWEDEN. WE8MSWIN1252

3. Restart the client. Examples, if you are using Toad restart TOAD for the changes to take effect.
