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
