Follow this steps to active a MySQL connection (I used this for my local MAMP setup)
1) Install DB navigator plugin: Settings >> plugins >> "available" tab
2) Download MySQL jdbc connector >> http://www.mysql.com/downloads/connector/j/
3) Unpack MySQL jdbc connector to a directory (ex: /home/documents/mysql_connector)
4) Add a DB connection: Settings >> DB Connection
Example for MySQL
Name: personal connection name (ex: MAMP MySQL)
Description: some more information (ex: local mamp mysql server)
Driver Library: location of the MySQL jdbc connector (/home/documents/mysql_connector/mysql-connector-xxxx-bin.jar)
Driver: the perfered driver
URL: the connection URL with jdbc reference (ex: "jdbc:mysql://localhost:8889/")
user: the password for the mysql connection (ex MAMP: root)
password: the password for the mysql connection (ex MAMP: root)
