oracle字符集设置utf 修改Oracle数据库的字符集为gbk

1、改客户端字符集:通过WINDOWS的运行菜单运行Regedit,修改注册表

Start -> Run -> Rededit <-|

Under registry Editor - > HKEY_LOCAL_MACHINE -> SOFTWARE ->ORACLE->KEY_XE->RIGHT WINDOW DOUBLE CLICK NLS_LANG -> CHANGE VALUE TO "AMERICAN_AMERICA.UTF8" ->OK ->CLOSE REGISTRY

正确设置ORACLE客户端字符集的方法:

oracle客户端字符集设置需要和服务器端一致,否则会出现乱码问题。

首先连接服务器,查询服务器端设置:

select * from v$nls_parameters;

找到:

NLS_LANGUAGE

NLS_TERRITORY

NLS_CHARACTERSET

环境变量nls_lang便是由这三部分组成

NLS_LANG = language_territory.charset

比如:

NLS_LANG = American_Japan.JA16SJIS

2、改服务器端字符集,通过ORACLE的SQL PLUS命令窗口改

在SQL*PLUS 中,以DBA登录

conn 用户名 as sysdba

然后执行以下命令

>shutdown immediate; (把database停了)

>startup mount; (把database重开去可更改情況)

>alter system enable restricted session;

>alter system set job_queue_processes=0;

>alter system set aq_tm_processes=0;

>alter database open;

>alter database character set utf8;

OR

>alter database character set internal_use utf8;

>shutdown immediate;

>startup; (重开正常oracle)

ORACLE数据库字符集修改完成!
