Hi, I'm struggling to express a query in DBIC. I've got the following situation:

    table events {
        id    primary key,
        name  varchar
    }

    table sessions {
        id       primary key,
        event    references events(id),
        starts   datetime
    }

I have the appropriate DBIx classes set up, including the proper has_many() and belongs_to() relationships. So each event can have multiple sessions. I need a list of events, ordered their earliest start date. The SQL for this would be:

    select  e.name, s.starts
      from  events e
      join  sessions s on e.id = s.event
      join  ( select  event, min(starts) as starts
                from  sessions
               group  by event
            ) as t
        on  s.event = t.event
       and  s.time  = t.starts

But how do I convert this to a DBIC expression? I'd appreciate your help
