Connecting MATLAB and MySQL with the JDBC Driver

Question

I bought the book Undocumented MATLAB by Yair Altmam; in chapter 2.2 of the book he discusses database connectivity and using the JDBC to connect to databases. I followed th

Answer 1

My first suspicion is your java class path. Instead of:

javaclasspath('mysql-connector-java-5.1.30-bin.jar')

Use

javaaddpath('C:\full\path\to\mysql-connector-java-5.1.30-bin.jar')

If that is not the problem, lets skip the DriverManager (doesn't really help much) and see if the code below works, (or where it fails).

d = com.mysql.jdbc.Driver;
urlValid = d.acceptsURL('jdbc:mysql://localhost:3306/test');  %Should return true
props = java.util.Properties;
props.put('user','root'); props.put('password','1234');
con = d.connect('jdbc:mysql://localhost:3306/test',props)

The DriverManager construct doesn't really help much. It seems to be designed to allow a developer to load up a bunch of drivers, and then connect to any supported database without knowing or caring what the DB implementation was (e.g. Mysql, Postgresql, Oracle etc.) I have never seen this as a useful feature. I think (hope?) that this is being used less in favor of a DataSource construct.

Regardless, if this is your first time connecting Mysql to Matlab, you probably are best just directing using the provided Driver class.
