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

收到,谢谢!
学习了 我很讨厌密码里有这个@ 字符
就是,为啥密码里要写个@符号,那sqlplus登陆的时候也不方便啊
在windows下应该这样写:
exp scott/"""tiger@xx"""
即:密码外面包括三对双引号
不同平台的转义是有所不同的,谢谢补充!
Thank you for your help!
