Clojure and MySQL

Here's the magical connection incantation to get Clojure and MySQL talking:

(def *db* {:classname "com.mysql.jdbc.Driver" :subprotocol "mysql" :subname "//your-server/your-db" :user "your-user" :password "your-password"})

Assumptions - you're using

  • Stephen C. Gilardi's clojure.contrib.sql library, and

  • MySQL's Connector/J JDBC driver, with mysql-connector-java-5.1.7-bin.jar in your Clojure classpath.

Clojure is elegant. It's from the future, with features like support for software transactional memory. Meantime, it's a close personal friend of Java, so it plays well with more mundane tools. I get a buzz when that happens. I've flirted with lisps before, but this one feels like a keeper.

Incidentally, the Connector/J license defaults to GPL, so it may contaminate your application like ice-nine. Hail Bokonon!
