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_MACHINESOFTWAREORACLEKEY_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,后不提示错误。但是 新建命令窗口里的中文乱码,后来又改回来了。暂时先这样。以后解决,
