PL/SQL database character set(AL32UTF8) and Client character set(ZHS16GBK) are different

启动PL/SQL Developer 报字符编码不一致错误

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_Oracle_10g.

打开注册表,通过命令regedit。找到到文中提示的路径，发现NLS_LANG键的值为:

SIMPLIFIED CHINESE_CHINA.ZHS16GBK

修改为：SIMPLIFIED CHINESE_CHINA.AL32UTF8即可
