Oracle用户密码含有特殊字符的处理办法

发布时间: 2017-06-16 11:02:44

在设置Oracle密码时,我们经常会将密码设置的特别复杂(一般由字母、数字和特殊符号组成),值得注意的是在有特殊符号时修改密码或着导入导出数据时会遇到很多不必要的麻烦,本文中将会对此情况进行详细的解释和说明:

注:本文中,将以特殊符号“/”为例。

Linux环境下,使用Oracle数据库10g

修改密码

[oracle@olivenan oracle]$ sqlplus ‘/as sysdba’

SQL》 alter user test identified by aa/aa;

alter user test identified by aa/aa

*

ERROR at line 1:

在此使用“”

SQL》 alter user test identified by “aa/aa”;

此处应该进行转义使用 “ ”处理密码,使用 ‘ ’处理用户名和密码

[oracle@olivenan oracle]$ exp ‘test/“aa/aa”’ file=test.dmp buffer=65536
