New ro rails: what mysql lib comes with Ruby/RoR on windows?

After you install the Ruby and MySQL you must install Ruby's MySQL
interface. Then you can load it in your script to connect to the
database. To make the connection you must provide the host, username
and password.

require 'mysql'

db_con = Mysql.new("localhost", "ruby", "password", "mydb")
result = db_con.query("Select * from MyTable")
result.each_hash do |r|
  print "#{r['column1']}"
end

Read the README file to see what classes are available. Check out the
online documentation for interacting with the database.

Rails needs the MySQL driver installed on the machine. It also
requires the connection parameters to be specified in the database.yml
file. I don't know if you can use the Rails framework classes for
connecting to the database.
