创建脚本，$ORACLE_HOME/sqlplus/demo/demobld.sql
删除脚本，$ORACLE_HOME/sqlplus/demo/demodrop.sql
创建后执行，
alter table emp add constraint emp_pk primary key(empno); ---在emp表中empno列添加主键
alter table dept add constraintdept_pk primary key(deptno); ---在dept表中deptno列添加主键
alter table emp add constraint emp_fk_dept foreign key(deptno) references dept; ---在emp表中关联dept表中deptno列
alter table emp add constraint emp_fk_emp foreign key(mgr) references emp; ---在emp表中关联emp表中mgr列
oracle 11g中创建scott用户的脚本：
创建脚本：$ORACLE_HOME/rdbms/admin/utlsampl.sql
删除用户语句：drop user scott;
例子：
[oracle@enmoedu1 admin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/rdbms/admin
SQL> @utlsampl
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
[oracle@enmoedu1 admin]$
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> conn scott/tiger;
Connected.
删除scott用户
SQL> conn / as sysdba
Connected.
SQL> drop user scott cascade;
User dropped.
如果没有脚本，也可以手工创建样例表到其他用户
SQL> create user only identified by oracle;
User created.
SQL> grant connect,resource to only;
Grant succeeded.
执行以下语句
DROP USER SCOTT CASCADE;
DROP USER ADAMS CASCADE;
DROP USER JONES CASCADE;
DROP USER CLARK CASCADE;
DROP USER BLAKE CASCADE;
DROP PUBLIC SYNONYM PARTS;
CONNECT only/oracle ####对应样例表建立的用户
