-- 使用超级管理员登录
CONN sys/change_on_install AS SYSDBA ;
-- 创建c##scott用户
CREATE USER c##scott IDENTIFIED BY tiger ;
-- 为用户授权
GRANT CONNECT,RESOURCE,UNLIMITED TABLESPACE TO c##scott CONTAINER=ALL ;
-- 设置用户使用的表空间
ALTER USER c##scott DEFAULT TABLESPACE USERS;
ALTER USER c##scott TEMPORARY TABLESPACE TEMP;
-- 使用c##scott用户登录
CONNECT c##scott/tiger
==退出plus 重新登录一次
建议使用sql devploer 链接scott执行以下脚本。
-- 创建数据表
CREATE TABLE dept (
deptno
NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY,
dname
VARCHAR2(14) ,
loc
VARCHAR2(13)
) ;
CREATE TABLE emp (
empno
NUMBER(4) CONSTRAINT PK_EMP PRIMARY KEY,
ename
VARCHAR2(10),
job
VARCHAR2(9),
mgr
NUMBER(4),
hiredate
DATE,
sal
NUMBER(7,2),
comm
NUMBER(7,2),
deptno
NUMBER(2) CONSTRAINT FK_DEPTNO REFERENCES DEPT
);
CREATE TABLE bonus (
enamE
VARCHAR2(10) ,
job
VARCHAR2(9) ,
sal
NUMBER,
comm
NUMBER
) ;
CREATE TABLE salgrade (
grade
NUMBER,
losal
NUMBER,
hisal
NUMBER
);

tips：到这里Scott用户里面就有数据了 可以先测试一下
范例：查询emp表数据（指令之后要使用“;”完结）
SELECT * FROM emp ;
范例：使用ed命令调用本机记事本程序
ED mldn
范例：使用SYS用户登录
CONN sys/change_on_install AS SYSDBA ;
范例：在sys用户中查询c##scott.emp表数据
SELECT * FROM c##scott.emp ;
范例：使用sys用户以管理员方式登录
CONN sys/change_on_install AS SYSDBA ;
范例：将CDB的切换到PDB
ALTER SESSION SET CONTAINER=pdbmldn ;
范例：打开PDBMLDN可插入数据库
ALTER DATABASE pdbmldn OPEN ;
范例：通过CDB打开PDBMLDN可插入数据库
ALTER PLUGGABLE DATABASE pdbmldn OPEN ;
范例：在PDBMLDN下察看scott与sh用户是否存在
SELECT username FROM dba_users WHERE username='SCOTT' OR username='SH' ;
范例：查询scott用户
SELECT * FROM scott.emp ;
范例：切换回CDB容器
ALTER SESSION SET CONTAINER=CDB$ROOT ;
范例：察看dept的表结构
DESC dept ;
范例：使用copy指令
HOST COPY D:\mldn.sql D:\hello.sql
范例：查询emp表
SELECT * FROM emp ;
