*第 1 行出现错误:ORA-01918: 用户 ‘SCOTT’ 不存在
找到scott.sql 文件
SQL> @D:\tudou\product\11.2.0\dbhome_1\RDBMS\ADMIN\scott.sql
SQL> conn system/weiwei as sysdba
已连接。
SQL> show user
USER 为 “SYS”
SQL> alter user scott identified by weiwei;
用户已更改。
SQL> conn scott/weiwei;
已连接。
SQL> show user
USER 为 “SCOTT”
注意.如果scott.sql文件不存在的话，我们可以自己手动建一个。
新建文本文档将以下内容复制到文件中，然后保存为scott.sql，放到2中的文件夹中，再按照2中的步骤
