相信所有使用Oracle的用户，尤其是“老鸟”们一定对Oracle数据库中的SCOTT用户及其数据表情有独钟。几乎所有学习和使用Oracle用户的人员都是从SCOTT用户及其数据表开始逐步了解Oracle数据库的。
但是在Oracle 12c中，正常安装配置好数据库之后，却没有了SCOTT用户；尤其是在创建了PDB后。那么如何在Oracle 12c 中的PDB中创建SCOTT用户及其数据表呢？
下面来介绍：
首先查看Oracle 12c 的PDB数据库状态，并且打开PDB数据库。
SQL> SELECT con_id,NAME,OPEN_MODE,restricted from v$PDBS; CON_ID NAME OPEN_MODE RES---------- -------------------- ---------- --- 2 PDB$SEED READ ONLY NO 3 BEANPDB READ WRITE YES
然后，以SYS用户的身份连接到PDB数据库（此处为 beanpdb）
SQL> conn sys/密码@beanpdb as sysdba;已连接。
然后创建SCOTT用户
create user scott identified by SCOTT用户密码 account unlock;
此时SCOTT用户并不能连接，因为缺少必要的权限。所以接下来先进行授权操作。
SQL> grant create user,drop user,alter user,create any view,connect,resource,dba,create session,create any sequence to scott;授权成功。
授权成功以后，使用SCOTT用户及其密码连接数据库。
此处说明：必要时需要SYS用户进行授权
grant restricted session to scott;
SQL> conn scott/tiger_123@beanpdb;已连接。
查看当前用户信息
SQL> show user;USER 为 "SCOTT"
然后执行脚本
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);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,'SCOTT','ANALYST',7566,to_date('13-7-87','dd-mm-rr')-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('13-7-87', 'dd-mm-rr')-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);CREATE TABLE BONUS ( ENAME VARCHAR2(10) , JOB VARCHAR2(9) , SAL NUMBER, COMM NUMBER ) ;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; 执行完成后，验证数据库表是否创建成功。
至此，就可以像以前一样对SCOTT用户下的数据库表进行操作了。
