-- 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。

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 ;
