connection of MATLAB 7.0 and MYSQL

Question

I want to connect MATLAB with MYSQL.I dont know the procedure.In MATLAB help it says about some drivers which confuses me alot.Can someone please guide me!please tell me the

Answer 1

I use JDBC to connect from MATLAB to mySQL database. Works seamlessly.

• First download JDBC driver for mySQL from here: http://www.mysql.com/downloads/connector/j/
• Unpack mysql-connector-java-x.x.xx-bin.jar (the latest version) file from the archive into a folder
• In the beginning of your script add the path to this jar file, then you can connect to a database and so on.

Here is an example of connecting to and querying public human genome database:

%# add path to the JAR file you just installed to Java dynamic classpath
javaaddpath('h:\Documents\MATLAB\myJavaClasses\mysql-connector-java-5.1.12-bin.jar')
%# connection parameteres
host = 'genome-mysql.cse.ucsc.edu';
user = 'genome';
password = '';
dbName = 'hg18'; 
%# JDBC parameters
jdbcString = sprintf('jdbc:mysql://%s/%s', host, dbName);
jdbcDriver = 'com.mysql.jdbc.Driver';

%# Create the database connection object
conn = database(dbName, user , password, jdbcDriver, jdbcString);

gene = 'NF1';
if isconnection(conn) % check to make sure that we successfully connected
    qry = sprintf('SELECT geneName, chrom, txStart, txEnd FROM refFlat WHERE geneName=''%s''',gene);
    rs = fetch(exec(conn, qry));
    rsdata = get(rs, 'Data');
end
