通常我们在设置Oracle密码时会将密码设置的比较复杂，一般有字母数字特殊符号组成但是在有特殊符号时，修改密码或着导入导出数据时会遇到麻烦，下文便是对该情况下的解释说明：本文以特殊符号“/”作为例子一、Linux环境，数据库为Oracle10g1、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

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

此处应该使用""
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

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，此处省略

二、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";

User altered.

SQL>

C:\Documents and Settings\w>exp test/aa/aa file=aa.dmp buffer=65536

Export: Release 9.2.0.1.0 - Production on Wed May 17 14:58:50 2006

EXP-00004: invalid username or password
Username:
Password:
EXP-00056: ORACLE error 1017 encountered
ORA-01017: invalid username/password; logon denied
Username: ^Z^Z

EXP-00030: Unexpected End-Of-File encountered while reading input
EXP-00000: Export terminated unsuccessfully

此处使用""" """来处理用户密码是6个双引号

C:\Documents and Settings\w>exp test/"""aa/aa""" file=aa.dmp buffer=65536

Export: Release 9.2.0.1.0 - Production on Wed May 17 14:59:10 2006

Connected to: Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production
Export done in WE8ISO8859P1 character set and AL16UTF16 NCHAR character set
server uses ZHS16GBK character set (possible charset conversion)
