oracle11gR2下scott用户以及表的建立
在oralce数据库安装完成之后，没有scott用户以及练习表，如何建立用户以及系统提供的表呢？
操作步骤：
找到系统带的sql文件（utlsample.sql）
[root@kyeup01 admin]# pwd
/oracle/app/oracle/product/11.2.0/rdbms/admin
[root@kyeup01 admin]# ll utlsampl.sql
-rw-r--r--. 1 oracle oinstall 3676 6月 2 2006 utlsampl.sql
根据SQL的内容操作
新建用户并授权
-- 删除系统带的用户
DROP USER SCOTT CASCADE;
DROP USER ADAMS CASCADE;
DROP USER JONES CASCADE;
DROP USER CLARK CASCADE;
DROP USER BLAKE CASCADE;
<!-- more -->
-- 授权scott相应的权限
GRANT CONNECT,RESOURCE,UNLIMITED TABLESPACE TO SCOTT IDENTIFIED BY tiger;
DROP PUBLIC SYNONYM PARTS;
scott登录
[oracle@kyeup01 admin]$ sqlplus '/as sysdba'

查询表（使用pl/sql）
疑问
以上的方法可能不是最优的方法，相当于把utlsample.sql手工执行了。
网上的资料大都是这样执行的：
[oracle@kyeup01 admin]$ sqlplus '/as sysdba'

其实命令操作错误，正确的操作如下：
[oracle@kyeup01 admin]$ sqlplus '/as sysdba'
