sqldeveloper乱码问题

我在oracle sqldeveloper创建的表 表中有字段的注释

但是我登录到plsqldeveloper时查出来的字段注释是“？”符号 查了一下资料

在sqldeveloper命令： select * from v$nls_parameters;查出字符集

Sql代码

1.  
2.  
3. SQL>select*fromv$nls_parameters;
5. PARAMETERVALUE
6. --------------------------------------------------------------------------------------------------------------------------------
7. NLS_LANGUAGESIMPLIFIEDCHINESE

10. NLS_ISO_CURRENCYCHINA
11. NLS_NUMERIC_CHARACTERS.,

22. NLS_NCHAR_CHARACTERSETUTF8
23. NLS_COMPBINARY
24. NLS_LENGTH_SEMANTICSBYTE
25. NLS_NCHAR_CONV_EXCPFALSE

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

 

退出再次登录

乱码解决 OK
