-- 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

);

-- 插入测试数据 —— dept

INSERT INTO dept VALUES    (10,'ACCOUNTING','NEW YORK');

INSERT INTO dept VALUES (20,'RESEARCH','DALLAS');

INSERT INTO dept VALUES    (30,'SALES','CHICAGO');

INSERT INTO dept VALUES    (40,'OPERATIONS','BOSTON');

-- 插入测试数据 —— emp

INSERT INTO emp VALUES (7369,'SMITH','CLERK',7902,to_date('17-12-1980','dd-mm-yyyy'),800,NULL,20);

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 ;
