1、数据库环境搭建
(安装oracle数据库就不介绍了,如果oracle搭建好了可以不看第一步 ,直接看第二步骤ODBC环境搭建)
先cmd登陆oracle数据库
sqlplus sys as sysdba
创建名为zwj密码为1234的用户
create user zwj identified by 1234;
给新创建的zwj用户添加connrct和resource权限
SQL> grant connect,resource to zwj;
可视化登陆
运行以下SQL代码 (其实不运行也可以,只要自己在创建oracle数据表然后添加数据就行了,这样可以方便matlab读取数据表的数据)
-- 创建数据表 CREATE TABLE dept ( deptno NUMBER(2) CONSTRAINT PK_DEPT PRIMARY KEY, dname VARCHAR2(14) , loc VARCHAR2(13) ) ; 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 ); CREATE TABLE bonus ( enamE VARCHAR2(10) , job VARCHAR2(9) , sal NUMBER, comm NUMBER ) ; CREATE TABLE salgrade ( grade NUMBER, losal NUMBER, hisal NUMBER ); -- 插入测试数据 —— 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'); -- 插入测试数据 —— emp 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('19-04-1987','dd-mm-yyyy')-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('23-05-1987','dd-mm-yyyy')-51,1100,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); -- 插入测试数据 —— salgrade 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); -- 事务提交 COMMIT;
创建了数据表
查询一下数据
2、ODBC环境搭建
控制面板->管理工具->ODBC 数据源(64 位)->添加DSN
选择添加oracle数据源
数据源名称随便写,然后点击Test Connection
服务名:ORCL 用户名填:zwj 密码:1234
测试链接成功
3、 matlab运行程序
clear,clc; conn = database('oracle','zwj','1234'); curs=exec(conn, 'select * from DEPT'); curs=fetch(curs); data=curs.Data close(curs); close(conn);
