今天在做数据导出的时候，由于用户名的密码使用的是特殊字符，所以遇到了错误
代码：“EXP-00056: 遇到
ORACLE 错误 12154”，网上查找原因，需要用引号扩起来，但是os不同，方式也不同:
windows os: exp username/"""password"""@devdb --3个双引号扩密码
linux/unix os: exp 'username/"password"@devdb' --1个双引号扩密码，1个单引号扩全部
实验结果如下：
1.创建带有特殊字符密码的用户
C:\Documents and Settings\Home>sqlplus /nolog

SQL> connsys/oracle@devdbas sysdba
已连接。
SQL> create user exp identified by "12345!@#$%";
用户已创建。
SQL> grant connect, resource to exp;
授权成功。
SQL> conn exp/"12345!@#$%"@devdb2
已连接。
SQL> create table table1 as select * from dual;
表已创建。
SQL> exit
2.windows os导出测试
