我是靠谱客的博主帅气板凳，最近开发中收集的这篇文章主要介绍ORACLE数据库基础练习表EMP\DEPT \SALGRADE脚本，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

--如果数据库本身已经有同名的表，不能重复创建的 
DROP TABLE EMP;
DROP TABLE DEPT;
DROP TABLE SALGRADE;

--创建员工信息表 
CREATE TABLE EMP
       (EMPNO NUMBER(4) NOT NULL,
        ENAME VARCHAR2(10),
        JOB VARCHAR2(9),
        MGR NUMBER(4),
        HIREDATE DATE,
        SAL NUMBER(7, 2),
        COMM NUMBER(7, 2),
        DEPTNO NUMBER(2));
