如何查看数据库的字符集？


软件环境：
1、Windows NT4.0+ORACLE 8.0.4
2、ORACLE安装路径为：C:\ORANT

实现方法：
SQL> conn sys/change_on_install
SQL> desc props$
SQL> set arraysize 1
SQL> col value$ format a40 --格式化value$的输出为40个字符宽
SQL> select name,value$ from props$ where name='NLS_CHARACTERSET';

SQL> conn system/manager
SQL> select * from nls_database_parameters;
SQL> select * from V$NLS_PARAMETERS;

SQL> select * from nls_database_parameters;
