oracle 11g XE 学习版添加scott用户方法全步骤
安装企业版的orcale是不是太费时费力了？若只是学习用途的话，不妨试试轻便版的XE版本，同样是官网下载的，但是这个安装起来比完整版简便多了。
首先，你得先安装好orcale 11g XE 版本；（这里暂时不细说，有需要后续会补充。）
然后，登陆系统管理员用户，
在命令行输入SQLPLUS，连接，然后使用管理员登陆；
sys\(此处为你设置的密码) as sysdba
其次，创建用户：
create user scott identified by tiger;
授权：
grant connect,resource,dba to scott;
添加数据脚本内容：

到这，用户SCOTT就基本创建完成了，但是还没完，SCOTT刚创建好并没有解锁，还不能用于PL/SQL登录，所以还需要以下步骤：
alter user scott identified by tiger; 修改scott密码
alter user scott account unlock; 解锁用户
conn scott/tiger (以scott模式登录)
show user (看看当前用户是否是scott)
select * from emp;执行这步，就能看到我们想看到的那几张表了;
格式不太规整，没关系，我们赶紧登陆PL/SQL看看：
赶紧SELECT * FROM EMP;
出现：
嗯，完成了。
