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。
