Oracle XE: ORA-12899: Valor muito grande para a coluna...

*******************************************************************
Estou com o seguinte problema: Instalei o Oracle 10g XE e criei
uma
> tabela com um campo que suporta 30 caracteres - varchar2(30) - e
estou
> tentando inserir a seguinte linha mas dá um erro que segue abaixo:
>
> este comando funciona normal
> CREATE TABLE operacao_nota
> (
> codigo NUMERIC(8) NOT NULL,
> descricao VARCHAR2(30) NOT NULL,
> CONSTRAINT pk_operacao_nota_codigo PRIMARY KEY (codigo)
> );
*******************************************************************

Este erro ocorreu pq o valor de NLS_CHARACTERSET está como AL32UTF8.

Se alterar o valor para WE8MSWIN252 o erro deixa de ocorrer.

No charset "AL32UTF8", o 32 significa qua a base de dados ao armazenar caracteres acima de ASCII-127 (ie, caracteres acentuados, e especiais como o sinal de euro - NÃO É só "vogais e consoantes"!! ), vai poder usar até 32 bits (4 bytes) para esses
caracteres, e o datatype VARCHAR2(30) está reservando apenas 30
bytes.

How to Delete All Objects for a User in Oracle

Detail

Normally, it is simplest to drop and add the user. This is the preferred method if you have system or sysdba access to the database.
If you don't have system level access, and want to scrub your schema, the following sql will produce a series of drop statments, which can then be executed.

select 'drop '||object_type||' '|| object_name|| DECODE(OBJECT_TYPE,'TABLE',' CASCADE CONSTRAINTS;',';')
from user_objects

Then, I normally purge the recycle bin to really clean things up. To be honest, I don't see a lot of use for oracle's recycle bin, and wish i could disable it... but anyway:

purge recyclebin;

This will produce a list of drop statements. Not all of them will execute - if you drop with cascade, dropping the PK_* indices will fail. But in the end, you will have a pretty clean schema. Confirm with:

select * from user_objects
