Your best bet is to download the appropriate drivers - either
haskelld-hdbc-mysql or haskelldb-hsql-mysql. If you get the haskelldb
sources via darcs, you can also look in the test directory to see how the
connections are established.

In my specific case, I am using PostgreSQL and by login  function looks like

-- ^ Returns a function which can log into the database and perform
login :: MonadIO m => String -> Int -> String -> String -> String ->
(Database -> m a) -> m a
login server port user password dbname = postgresqlConnect [("host",
  ("port", show port),
  ("user", user),
  ("password", password),
  ("dbname", dbname)]
