MySQL中創建Oracle中SCOTT數據示例

一、建立 scott 數據庫

CREATE DATABASE scott;

二、建立 scott 數據庫中的 dept 表

CREATE TABLE dept(
    deptno      INT UNSIGNED PRIMARY KEY COMMENT '部門編號',
    dname       VARCHAR(15) COMMENT '部門名稱',
    loc         VARCHAR(50) COMMENT '部門所在位置'
) COMMENT='部門表';

插入數據庫 scott 中表 dept 的初始化數據

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');

三、建立 scott 數據庫中的 emp 表

CREATE TABLE emp(
    empno           INT UNSIGNED AUTO_INCREMENT PRIMARY KEY COMMENT '僱員編號',
    ename           VARCHAR(15) COMMENT '僱員姓名',
    job             VARCHAR(10) COMMENT '僱員職位',
    mgr             INT UNSIGNED COMMENT '僱員對應的領導的編號',
    hiredate        DATE COMMENT '僱員的僱傭日期',
    sal             DECIMAL(7,2) COMMENT '僱員的基本工資',
    comm            DECIMAL(7,2) COMMENT '獎金',
    deptno          INT UNSIGNED COMMENT '所在部門',
    FOREIGN KEY(deptno) REFERENCES dept(deptno)
) COMMENT='僱員表';

插入數據庫 scott 中表 emp 的初始數據

INSERT INTO emp VALUES    (7369,'SMITH','CLERK',7902,'1980-12-17',800,NULL,20);
INSERT INTO emp VALUES    (7499,'ALLEN','SALESMAN',7698,'1981-2-20',1600,300,30);
INSERT INTO emp VALUES    (7521,'WARD','SALESMAN',7698,'1981-2-22',1250,500,30);
INSERT INTO emp VALUES    (7566,'JONES','MANAGER',7839,'1981-4-2',2975,NULL,20);
INSERT INTO emp VALUES    (7654,'MARTIN','SALESMAN',7698,'1981-9-28',1250,1400,30);
INSERT INTO emp VALUES    (7698,'BLAKE','MANAGER',7839,'1981-5-1',2850,NULL,30);
INSERT INTO emp VALUES    (7782,'CLARK','MANAGER',7839,'1981-6-9',2450,NULL,10);
INSERT INTO emp VALUES    (7788,'SCOTT','ANALYST',7566,'87-7-13',3000,NULL,20);
INSERT INTO emp VALUES    (7839,'KING','PRESIDENT',NULL,'1981-11-17',5000,NULL,10);
INSERT INTO emp VALUES    (7844,'TURNER','SALESMAN',7698,'1981-9-8',1500,0,30);
INSERT INTO emp VALUES    (7876,'ADAMS','CLERK',7788,'87-7-13',1100,NULL,20);
INSERT INTO emp VALUES    (7900,'JAMES','CLERK',7698,'1981-12-3',950,NULL,30);
INSERT INTO emp VALUES    (7902,'FORD','ANALYST',7566,'1981-12-3',3000,NULL,20);

四、建立數據庫 scott 中的 salgrade 表，工資等級表

CREATE TABLE salgrade(
    grade       INT UNSIGNED COMMENT '工資等級',
    losal       INT UNSIGNED COMMENT '此等級的最低工資',
    hisal       INT UNSIGNED COMMENT '此等級的最高工資'  
) COMMENT='工資等級表';

插入數據庫 scott 中表 salgrade 的初始數據

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);

五、建立數據庫 scott 的 bonus 表，工資表

CREATE TABLE bonus(
    ename       VARCHAR(10) COMMENT '僱員姓名',
    job         VARCHAR(9) COMMENT '僱員職位',
    sal         DECIMAL(7,2) COMMENT '僱員工資',
    comm        DECIMAL(7,2) COMMENT '僱員資金'  
) COMMENT='工資表';
