Oracle12C如何导入scott用户

Oracle12C如何导入scott用户

1.开始——运行——cmd 连接到数据库

用语句：sqlplus SYS/CHANGE_ON_INSTALL@ORALCE12C as sysdba

2.创建c##scott用户

CREATE USER c##scott IDENTIFIED BY tiger ;

3.为用户授权

GRANT CONNECT,RESOURCE,UNLIMITED TABLESPACE TO c##scott CONTAINER=ALL ;

4.设置用户使用的表空间

ALTER USER c##scott DEFAULT TABLESPACE USERS;

ALTER USER c##scott TEMPORARY TABLESPACE TEMP;

以上创建账户。一下开始创建表，需要换用户登录。

5. 使用c##scott用户登录

CONNECT c##scott/tiger

先退出：exit；或者重新打开：开始——运行——cmd 连接到数据库
用语句：sqlplus c##scott/tiger@ORALCE12C

6. 删除数据表

（新建时不用删除）

DROP TABLE emp  PURGE ;
DROP TABLE dept PURGE ;
DROP TABLE bonus PURGE ;
DROP TABLE salgrade PURGE ;

7. 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 );

8. 插入测试数据 —— dept

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

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

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

9. 插入测试数据 —— emp

INSERT INTO emp VALUES(7499,'ALLEN','SALESMAN',7698,to_date('20-2-1981','dd-mm-yyyy'),1600,300,30);

INSERT INTO emp VALUES(7521,'WARD','SALESMAN',7698,to_date('22-2-1981','dd-mm-yyyy'),1250,500,30);
