Oracle12g添加c##scott用户

1.前言

在Oracle12c中，已经没有了scott这一实例用户。Oracle学习者们可以通过新建hr用户或是新建scott用户，来完成对Oracle的学习。

2.具体流程

登录系统用户

 conn / as sysdba;

删除已有的用户(可选)

   DROP USER c##scott cascade;

新建用户，授予权限，连接

CREATE USER c##scott identified by tiger;             
GRANT CREATE SEQUENCE to c##scott ;
GRANT UNLIMITED TABLESPACE to c##scott ;
GRANT CREATE SESSION to c##scott ;
GRANT CREATE SYNONYM to c##scott ;
GRANT ALTER SESSION to c##scott;
GRANT CREATE DATABASE LINK to c##scott;
GRANT CREATE VIEW to c##scott;
GRANT CREATE TABLE to c##scott;
ALTER USER c##scott DEFAULT TABLESPACE USERS;
ALTER USER c##scott TEMPORARY TABLESPACE TEMP;
conn c##scott/tiger

新建表格并添加数据

-- DEPT表格
CREATE TABLE DEPT
       (DEPTNO NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY,
    DNAME VARCHAR2(14) ,
    LOC VARCHAR2(13) ) ;
-- EMP表格
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);
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');
INSERT INTO EMP VALUES
(7369,'SMITH','CLERK',7902,to_date('17-12-1980','dd-mm-yyyy'),800,NULL,20);
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);
INSERT INTO EMP VALUES
(7566,'JONES','MANAGER',7839,to_date('2-4-1981','dd-mm-yyyy'),2975,NULL,20);
INSERT INTO EMP VALUES
(7654,'MARTIN','SALESMAN',7698,to_date('28-9-1981','dd-mm-yyyy'),1250,1400,30);
INSERT INTO EMP VALUES
(7698,'BLAKE','MANAGER',7839,to_date('1-5-1981','dd-mm-yyyy'),2850,NULL,30);
INSERT INTO EMP VALUES
(7782,'CLARK','MANAGER',7839,to_date('9-6-1981','dd-mm-yyyy'),2450,NULL,10);
INSERT INTO EMP VALUES
(7788,'c##scott','ANALYST',7566,to_date('13-JUL-87')-85,3000,NULL,20);
INSERT INTO EMP VALUES
(7839,'KING','PRESIDENT',NULL,to_date('17-11-1981','dd-mm-yyyy'),5000,NULL,10);
INSERT INTO EMP VALUES
(7844,'TURNER','SALESMAN',7698,to_date('8-9-1981','dd-mm-yyyy'),1500,0,30);
INSERT INTO EMP VALUES
(7876,'ADAMS','CLERK',7788,to_date('13-JUL-87')-51,1100,NULL,20);
INSERT INTO EMP VALUES
(7900,'JAMES','CLERK',7698,to_date('3-12-1981','dd-mm-yyyy'),950,NULL,30);
INSERT INTO EMP VALUES
(7902,'FORD','ANALYST',7566,to_date('3-12-1981','dd-mm-yyyy'),3000,NULL,20);
INSERT INTO EMP VALUES
(7934,'MILLER','CLERK',7782,to_date('23-1-1982','dd-mm-yyyy'),1300,NULL,10);
-- BONUS表格
CREATE TABLE BONUS
    (
    ENAME VARCHAR2(10)  ,
    JOB VARCHAR2(9)  ,
    SAL NUMBER,
    COMM NUMBER
    ) ;
-- SALGRADE表格
CREATE TABLE SALGRADE
      ( GRADE NUMBER,
    LOSAL NUMBER,
    HISAL NUMBER );
INSERT INTO SALGRADE VALUES (1,700,1200);
INSERT INTO SALGRADE VALUES (2,1201,1400);
INSERT INTO SALGRADE VALUES (3,1401,2000);
INSERT INTO SALGRADE VALUES (4,2001,3000);
INSERT INTO SALGRADE VALUES (5,3001,9999);
commit;

至此，新建c##scott用户完成，可以开始学习Oracle了。
