【赛迪网－it技术报道】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*plus: release 10.2.0.1.0 - production on wed may 17 14:33:32 2006

copyright (c) 1982, 2005, oracle. all rights reserved.

connected to:

oracle database 10g enterprise edition release 10.2.0.1.0 - production

with the partitioning, olap and data mining options

sql> alter user test identified by aa/aa;

alter user test identified by aa/aa

*

error at line 1:

ora-00922: missing or invalid option

在此使用""

sql> alter user test identified by "aa/aa";

user altered.

sql>

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

export: release 10.2.0.1.0 - production on wed may 17 14:32:10 2006

copyright (c) 1982, 2005, oracle. all rights reserved.

exp-00004: invalid username or password

username:

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

export: release 10.2.0.1.0 - production on wed may 17 14:32:52 2006

connected to: oracle database 10g enterprise edition release 10.2.0.1.0 - production

with the partitioning, olap and data mining options

export done in we8iso8859p1 character set and al16utf16 nchar character set

about to export specified users ...

. exporting pre-schema procedural objects and actions

...............

导出成功。

windows xp下，数据库为oracle9i

c:\documents and settings\w>sqlplus /nolog

sql*plus: release 9.2.0.1.0 - production on wed may 17 14:56:34 2006

sql> connect sys/olivenan as sysdba

connected.

sql> alter user test identified by aa/aa;

alter user test identified by aa/aa

*

error at line 1:

ora-00922: missing or invalid option

此处使用""

sql> alter user test identified by "aa/aa";
