-- 使用超級管理員登錄
CONN sys/change_on_install AS SYSDBA ;
-- 創建c##scott用戶
CREATE USER c##scott IDENTIFIED BY tiger ;
-- 為用戶授權
GRANT CONNECT,RESOURCE,UNLIMITED TABLESPACE TO c##scott CONTAINER=ALL ;
-- 設置用戶使用的表空間
ALTER USER c##scott DEFAULT TABLESPACE USERS;
ALTER USER c##scott TEMPORARY TABLESPACE TEMP;
-- 使用c##scott用戶登錄
CONNECT c##scott/tiger
==退出plus 重新登錄一次
建議使用sql devploer 鏈接scott執行以下腳本。
-- 創建數據表
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：到這裡Scott用戶裡面就有數據了 可以先測試一下
範例：查詢emp表數據（指令之後要使用“;”完結）
SELECT * FROM emp ;
範例：使用ed命令調用本機記事本程式
ED mldn
範例：使用SYS用戶登錄
CONN sys/change_on_install AS SYSDBA ;
範例：在sys用戶中查詢c##scott.emp表數據
SELECT * FROM c##scott.emp ;
範例：使用sys用戶以管理員方式登錄
CONN sys/change_on_install AS SYSDBA ;
範例：將CDB的切換到PDB
ALTER SESSION SET CONTAINER=pdbmldn ;
範例：打開PDBMLDN可插入資料庫
ALTER DATABASE pdbmldn OPEN ;
範例：通過CDB打開PDBMLDN可插入資料庫
ALTER PLUGGABLE DATABASE pdbmldn OPEN ;
範例：在PDBMLDN下察看scott與sh用戶是否存在
SELECT username FROM dba_users WHERE username='SCOTT' OR username='SH' ;
範例：查詢scott用戶
SELECT * FROM scott.emp ;
範例：切換回CDB容器
ALTER SESSION SET CONTAINER=CDB$ROOT ;
範例：察看dept的表結構
DESC dept ;
範例：使用copy指令
HOST COPY D:\mldn.sql D:\hello.sql
範例：查詢emp表
SELECT * FROM emp ;
