如何在Mysql数据库中创建Oracle数据库scott的几张表格



我们先来看看Oracle中scott用户几张表的数据结构:



==============================================================

              以下操作在Oracle数据库进行(如果需要)

==============================================================


创建表格:

CREATE TABLE dept
(
deptno INT PRIMARY KEY,
dname VARCHAR(14),
loc VARCHAR(13)
);
CREATE TABLE emp
       (EMPNO INT(4) PRIMARY KEY,
 ENAME VARCHAR(10),
 JOB VARCHAR(9),
 MGR INT(4),
 HIREDATE DATE,
 SAL DOUBLE,
 COMM DOUBLE,
 deptno INT,
FOREIGN KEY (deptno) REFERENCES dept(deptno));
CREATE TABLE  salgrade
(grade INT PRIMARY KEY,
losal INT,
hisal INT);

插入测试数据:

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,DATE(‘1980-12-17‘),800,NULL,20);
INSERT INTO emp VALUES
(7499,‘ALLEN‘,‘SALESMAN‘,7698,DATE(‘1981-2-20‘),1600,300,30);
INSERT INTO emp VALUES
(7521,‘WARD‘,‘SALESMAN‘,7698,DATE(‘1981-2-22‘),1250,500,30);
INSERT INTO emp VALUES
(7566,‘JONES‘,‘MANAGER‘,7839,DATE(‘1981-4-2‘),2975,NULL,20);
INSERT INTO emp VALUES
(7654,‘MARTIN‘,‘SALESMAN‘,7698,DATE(‘1981-9-28‘),1250,1400,30);
INSERT INTO emp VALUES
(7698,‘BLAKE‘,‘MANAGER‘,7839,DATE(‘1981-5-1‘),2850,NULL,30);
INSERT INTO emp VALUES
(7782,‘CLARK‘,‘MANAGER‘,7839,DATE(‘1981-6-9‘),2450,NULL,10);
INSERT INTO emp VALUES
(7788,‘SCOTT‘,‘ANALYST‘,7566,DATE(‘1987-4-19‘),3000,NULL,20);
INSERT INTO emp VALUES
(7839,‘KING‘,‘PRESIDENT‘,NULL,DATE(‘1981-11-17‘),5000,NULL,10);
INSERT INTO emp VALUES
(7844,‘TURNER‘,‘SALESMAN‘,7698,DATE(‘1981-9-8‘),1500,0,30);
INSERT INTO emp VALUES
(7876,‘ADAMS‘,‘CLERK‘,7788,DATE(‘1987-5-23‘),1100,NULL,20);
INSERT INTO emp VALUES
(7900,‘JAMES‘,‘CLERK‘,7698,DATE(‘1981-12-3‘),950,NULL,30);
INSERT INTO emp VALUES
(7902,‘FORD‘,‘ANALYST‘,7566,DATE(‘1981-12-3‘),3000,NULL,20);
INSERT INTO emp VALUES
(7934,‘MILLER‘,‘CLERK‘,7782,DATE(‘1982-1-23‘),1300,NULL,10);
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);



总结:创建表的时候将NUMBER换成int,varchar2换成varchar,datetime换成date,插入表的时候用DATE函数。


==============================================================

                   以下操作在Mysql用户进行

==============================================================

CREATE TABLE dept
(
deptno INT PRIMARY KEY,
dname VARCHAR(14),
loc VARCHAR(13)
);


CREATE TABLE emp
       (EMPNO INT(4) PRIMARY KEY,
 ENAME VARCHAR(10),
 JOB VARCHAR(9),
 MGR INT(4),
 HIREDATE DATE,
 SAL DOUBLE,
 COMM DOUBLE,
 deptno INT,
FOREIGN KEY (deptno) REFERENCES dept(deptno));


CREATE TABLE  salgrade
(grade INT PRIMARY KEY,
losal INT,
hisal INT);



===========================插入数据===========================

 (10,‘ACCOUNTING‘,‘NEW YORK‘);

 (20,‘RESEARCH‘,‘DALLAS‘);

 (30,‘SALES‘,‘CHICAGO‘);
