首先,不用说,当然是要安装oracle 数据库
这里可以参考,oracle11g 安装教程 (请点击查看安装教程)
现在比较多使用的是11g版本,但现在市面上很多机构使用的仍然是10g或者更早的版本,不过总体的使用差不多。区别大家可以自己百度查找或者看文档。我这里就不一一赘述
我这里因为和公司的数据库有相连,就不建立数据库了,直接把需要的表emp(employee 员工表)、dept(部门表)、sal(工资表salary)创建在公司的测试库里面。
创建需要的语句如下:
--这是oracle的建表脚本,把一些比如varchar2改成varchar,number改成int,to_date()函数去掉就差不多了,其他的根据mysql语法自己改吧。 DROP TABLE DEPT;--如果有同名表,先删除 CREATE TABLE DEPT (DEPTNO NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY, DNAME VARCHAR2(14) , LOC VARCHAR2(13) ) ; DROP TABLE EMP;--如果有同名表,先删除 CREATE TABLE EMP (EMPNO NUMBER(4) CONSTRAINT PK_EMP PRIMARY KEY, ENAME VARCHAR2(10), JOB VARCHAR2(9), MGR NUMBER(4), HIREDATE DATE, SAL NUMBER(7,2), COMM NUMBER(7,2), DEPTNO NUMBER(2) CONSTRAINT FK_DEPTNO REFERENCES DEPT); 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,to_date('17-12-1980','dd-mm-yyyy'),800,NULL,20); INSERT INTO EMP VALUES (7499,'ALLEN','SALESMAN',7698,to_date('20-2-1981','dd-mm-yyyy'),1600,300,30); INSERT INTO EMP VALUES (7521,'WARD','SALESMAN',7698,to_date('22-2-1981','dd-mm-yyyy'),1250,500,30); INSERT INTO EMP VALUES (7566,'JONES','MANAGER',7839,to_date('2-4-1981','dd-mm-yyyy'),2975,NULL,20); INSERT INTO EMP VALUES (7654,'MARTIN','SALESMAN',7698,to_date('28-9-1981','dd-mm-yyyy'),1250,1400,30); INSERT INTO EMP VALUES (7698,'BLAKE','MANAGER',7839,to_date('1-5-1981','dd-mm-yyyy'),2850,NULL,30); INSERT INTO EMP VALUES (7782,'CLARK','MANAGER',7839,to_date('9-6-1981','dd-mm-yyyy'),2450,NULL,10); INSERT INTO EMP VALUES (7788,'SCOTT','ANALYST',7566,to_date('13-JUL-87')-85,3000,NULL,20); INSERT INTO EMP VALUES (7839,'KING','PRESIDENT',NULL,to_date('17-11-1981','dd-mm-yyyy'),5000,NULL,10); INSERT INTO EMP VALUES (7844,'TURNER','SALESMAN',7698,to_date('8-9-1981','dd-mm-yyyy'),1500,0,30); INSERT INTO EMP VALUES (7876,'ADAMS','CLERK',7788,to_date('13-7-87','dd-mm-yyyy'),1100,NULL,20); INSERT INTO EMP VALUES (7900,'JAMES','CLERK',7698,to_date('3-12-1981','dd-mm-yyyy'),950,NULL,30); INSERT INTO EMP VALUES (7902,'FORD','ANALYST',7566,to_date('3-12-1981','dd-mm-yyyy'),3000,NULL,20); INSERT INTO EMP VALUES (7934,'MILLER','CLERK',7782,to_date('23-1-1982','dd-mm-yyyy'),1300,NULL,10); DROP TABLE SALGRADE; CREATE TABLE SALGRADE --如果有同名表,先删除 ( GRADE NUMBER, LOSAL NUMBER, HISAL NUMBER ); 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); COMMIT;
