hi, i have a sql statement which has a subquery on itself. it gets all the unique invitees of a given event from table invitation. i came up with the sql but i don't know how to convert it into a named_scope which i can reuse in other places. please help.
sql: select * from invitations inv join (select event_id, user_id, max(invite_time) as last_invite_time from invitations group by event_id, user_id) as last_inv on inv.event_id = last_inv.event_id and inv.user_id = last_inv.user_id and inv.invite_time = last_inv.last_invite_time and inv.event_id = @event_id thanks batterhead -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
