sql语句

select

from
  `search_censuses`
where
  `search_censuses`.`id` in (
    select
      `search_census_dailies`.`search_census_id`
    from
      `search_census_dailies`
    where
      `search_censuses`.`id` = `search_census_dailies`.`search_census_id`
      and `score` >= '1246'
      and `score` <= '2345'
    order by
      `id` desc
