查看和修改Oracle服务器端字符集:

方法一:

1)       查看服务器端字符集:

select * from v$nls_parameters;

select * from nls_database_parameters;

select * from sys.props$;

2) 修改服务器端字符集(用sys用户):

首先执行:update props$ set value$ = 'WE8ISO8859P1' where name ='NLS_CHARACTERSET';

update props$ set value$ = 'china' where name ='NLS_LANGUAGE';

提交(commit),,然后,重新启动数据库;

3)用客户端工具(PL/SQL DEVELOP or PB etc.)查询数据库,若显示乱码,先查询出数据库端的字符集,然后,从注册表中修改NLS_LANG字段的值,可能为AMERICAN_AMERICA.WE8ISO8859P1或者SIMPLIFIED CHINESE_CHINA.ZHS16GBK或者NA等。

方法二:

alter system enable restricted session;

alter database ORCL character set ZHS16GBK;

alter database ORCL national character set ZHS16GBK;
