oracle怎么设置字符集,ORACLE系统字符集设置

like ‘8011’||lpad(#value#,8,’0′)//lpad

函数将8位的值为0的数据替换为value但是其位数不变。

修改Oracle客户端字符集方法:

1:可以通过修改注册表键值永久设置，类似于这样的键值:

HKEY_LOCAL_MACHINE/SOFTWARE/Oracle/HOME0下,

如一般的简体中文

nls_lang＝SIMPLIFIED CHINESE_CHINA.ZHS16GBK

2:查看数据库当前字符集参数设置

SQL> select userenv(‘language’) from dual;

USERENV(‘LANGUAGE’)

—————————————————-

SIMPLIFIED CHINESE_CHINA.ZHS16GBK

查看 Oracle11g 的字符集：

1、查看全部字符集： select name, value$ from props$ where name like ‘%NLS%’;

2、查看服务端的字符集： select userenv(‘language’) from dual;

HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE/KEY_OraDb11g_home1/ 中右边框中的

NLS_LANG 键所对应的值为即当前 Oracle 客户端使用的字符集，如 SIMPLIFIED

CHINESE_CHINA.ZHS16GBK，再如：american_america.al32utf8

3、查看服务端字符集： SQL> select * from

nls_database_parameters;

4、查看客户端字符集： SQL> select * from nls_instance_parameters;

5、查看 session

字符集： SQL> select * from nls_session_parameters;

6、修改字符集：

SQL> conn / as sysdba;

SQL> shutdown immediate;

SQL> startup mount;

SQL> alter system enable restricted session;

SQL> alter system set job_queue_processes =

0;

SQL> alter system set aq_tm_processes = 0;

SQL> alter database open;

SQL> alter database character set ZHS16GBK;

SQL> alter shutdown immedite;

SQL> startup;
