假如数据库网络连接串是db_wending, 密码是 dba/123,@lk.com
SQLPLUS下(密码用一对双引号括住):
SQL> alter user u_test identified by "dba/123,@lk.com";
SQL> conn u_test/"dba/123,@lk.com"@db_wending
Linux下(密码用一对双引号, 整体userid用对单引号括住):
$ exp 'u_test/"dba/123,@lk.com"@db_wending' file=u_test.dmp buffer=4096000
windows下(密码前后分别用三个双引号括住):
D:\> exp u_test/"""dba/123,@lk.com"""@db_wending file=u_test.dmp buffer=4096000
