Question

我正在尝试将Firebird 2.1数据库迁移到2.5，并且在默认字段中发生错误。我应该使用哪种字符集？



SET SQL DIALECT 3;

CREATE DATABASE 'F:\Sistemas\mga\DataBase\CRIAR.GDB'
USER 'SYSDBA' PASSWORD 'masterkey'
PAGE_SIZE 16384
DEFAULT CHARACTER SET NONE;

CREATE TABLE ESTOQUE (
    ID               INTEGER,
    FORNECEDOR_ID    INTEGER,
    FUNCIONARIOS_ID  INTEGER,
    ID_TABELA        INTEGER,
    DATA             DATE,
    QUANTIDADE       NUMERIC(15,2),
    VALOR_UNITARIO   NUMERIC(15,5) DEFAULT 0,
    TABELA           VARCHAR(100) CHARACTER SET NONE,
    SAFRA_ID         NUMERIC(18,0),
    VALOR_TOTAL      NUMERIC(15,2),
    TIPO             VARCHAR(100) CHARACTER SET NONE,
    PROPRIEDADE_ID   INTEGER,
    PLACAS           VARCHAR(100) CHARACTER SET NONE,
    NOTAS            VARCHAR(100) CHARACTER SET NONE,
    MOTORISTA        VARCHAR(100) CHARACTER SET NONE,
    BLOQUEADO        VARCHAR(3) CHARACTER SET NONE DEFAULT 'NÃO',
    DESCRICAO        BLOB SUB_TYPE 1 SEGMENT SIZE 80 CHARACTER SET NONE,
    FRETE            NUMERIC(15,2)
);

错误:: BLOQUEADO VARCHAR（3）CHARACTER SET NONEDEFAULT'NÃO'，



This operation is not defined for system tables.
unsuccessful metadata update.
STORE RDB$RELATION_FIELDS failed.
Malformed string.

我尝试：

SET NAMES WIN1252;
WIN1252
CHARACTER SET WIN1252,
CHARACTER SET ISO8859_1
COLLATE PT_BR

但是，这没关系


update ESTOQUE set BLOQUEADO='NÃO' ;

备份数据库并尝试使用以下选项进行恢复：

 c:\Program Files\Firebird\Firebird_2_5\bin\gbak.exe -R O c:\temp\my_backup.FBK my_new_database.fdb 
 -FIX_FSS_M WIN1252 -FIX_FSS_D WIN1252 -USER SYSDBA -PAS masterkey -V

格式错误的字符串IN默认字段
