解决PLSQL developer 乱码问题

在使用PLSQL developer 的过程中，我们使用遇到了乱码的问题，现在解决方案如下：

Sql代码  

1. SQL> select * from v$nls_parameters;  
2.    
3. PARAMETER                                                        VALUE  
4. ---------------------------------------------------------------- ----------------------------------------------------------------  
5. NLS_LANGUAGE                                                     SIMPLIFIED CHINESE  
6. NLS_TERRITORY                                                    CHINA

8. NLS_ISO_CURRENCY                                                 CHINA  
9. NLS_NUMERIC_CHARACTERS                                           .,

17. NLS_TIME_TZ_FORMAT                                               HH.MI.SSXFF AM TZR  
18. NLS_TIMESTAMP_TZ_FORMAT                                          DD-MON-RR HH.MI.SSXFF AM TZR  
19. NLS_DUAL_CURRENCY                                                ￥  
20. NLS_NCHAR_CHARACTERSET                                           UTF8  
21. NLS_COMP                                                         BINARY

NLS_LANGUAGE 对应 是SIMPLIFIED CHINESE

最后在我本机环境变量中增加

NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK

这样我再使用plsql就不会再出现乱码了。
