- 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。
