Oracle学习（二）之初始化scott用户

SCOTT用户是我们学习Oracle过程中一个非常重要的实验对象，在我们建立数据库的时候，如果是选择定制模式的话，SCOTT用户是不会默认出现的，不过我们可以通过使用几个简单命令来使这个用户出现。以下是解决方法（基于windows）:

    1.开始——运行——cmd
       输入：sqlplus / as sysdba 连接到数据库
       SQL>conn scott/tiger 如果scott不存在，会报ORA-01017的错误，并会断开连接
 
     2.我们以SYS用户重新连接
       SQL>conn sys/密码 as sysdba 
       然后在我们按照oracle的目录D:\JavaDevTools\oracle11g\app\oracle\product\11.2.0\server\rdbms\admin中（以我的这个目录为例）找到scott.sql的这个文件
       运行 SQL>@D:\JavaDevTools\oracle11g\app\oracle\product\11.2.0\server\rdbms\admin\scott.sql
       这样scott用户就被添加进来，默认密码是tiger
       SQL>conn scott/tiger 连接成功
       SQL>SHOW USER; 
       USER为“SCOTT”
     3.如果想修改scott的默认密码可以执行下面命令（先以sys权限登录:sqlplus / as sysdba）
       修改scott的登录密码
       SQL> alter user scott identified by gg;你再拿scott/gg来登录就可以了
     4.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D:\JavaDevTools\oracle11g\app\oracle\product\11.2.0\server\rdbms\admin的文件夹中，再按照2中的步骤
scott.sql
