plsql 登录后提示：

Database character set (AL32UTF8) and Client character set (ZHS16GBK) are different.
Character set conversion may cause unexpected results.

Note: you can set the client character set through the NLS_LANG environment variable or the NLS_LANG registry key in
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraClient11g_home2.
 


 

解决办法：修改注册表

 

打开注册表,‘开始’-‘运行’ 输入‘regedit’-确定。


 

找到提示中给出的路径，


 

找到 NLS_LANG 键，他的值原来是：SIMPLIFIED CHINESE_CHINA.ZHS16GBK


 

修改为：SIMPLIFIED CHINESE_CHINA.AL32UTF8


 

重新打开plsql ，登录，好了。
