在设置Oracle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

About to export specified users ... . exporting pre-schema procedural objects and actions
...............
导出成功。 更多关于Oracle
Windows Xp下,数据库为Oracle9i

在此处将使用""" """来处理用户密码
