MATLAB中访问数据库

oracle:

一、将OracleJDBC的JAR包拷贝到Matlab的相关目录下（$matlabroot/java/jar/toolbox）

sudo cp ojdbc6.jar /opt/local/MATLAB/R2017a/java/jar/toolbox/.

注意：2017a还只支持到jdk7，故只支持jdk8以上的ojdbc8.jar不可以。

二、配置matlab的classpath.txt
vi /opt/local/MATLAB/R2017a/toolbox/local/classpath.txt
添加如下行：
  $matlabroot/java/jar/toolbox/ojdbc6.jar

三、启动MATLAB并接数据库

>> clear
>> conn=database('xe','scott','tiger','oracle.jdbc.driver.OracleDriver','jdbc:oracle:thin:@127.0.0.1:1521:');
>> curs=exec(conn, 'select * from EMP');
>> curs = fetch(curs, 100);
>> AA = curs.Data;
>> AA

AA =

  14×8 cell 数组

四、其它数据库也类似：

要注意jdbc支持的Java版本:

pg:

postgresql-42.2.2.jre7.jar

>>conn=database('DBname','user','passwd','org.postgresql.Driver','jdbc:postgresql://127.0.0.1:5432/');

mysql:

mysql-connector-java-5.1.46-bin.jar
conn=database('DBname','user','passwd','com.mysql.jdbc.Driver','jdbc:mysql://localhost:3306/DBname');
