如何转义口令中的特殊符号（如@）

有用户问到这样一个问题，在进行导出操作时如何转义口令中的@符号？
由于缺省的Oracle会将@符号后面的字串当作服务名来解析，所以不加处理是不行的。
有的企业因为安全规则的需要，口令中都会加入@符号。
假定用户口令如下：
SQL> alter user eygle identified by "eygle@com";
User altered.
如果缺省导出会出现如下错误：
[oracle@jumper oracle]$ exp eygle/eygle@com file=eygle.dmp tables=test
Export: Release 9.2.0.4.0 - Production on Fri Jan 4 11:17:48 2008

EXP-00056: ORACLE error 12154 encountered
ORA-12154: TNS:could not resolve service name
EXP-00000: Export terminated unsuccessfully
通过转义，可以成功导出：
[oracle@jumper oracle]$ exp eygle/\"eygle@com\" file=eygle.dmp tables=test
Export: Release 9.2.0.4.0 - Production on Fri Jan 4 11:12:10 2008
