Question

我是ruby新手，无法将给定的查询转换为ruby查询，有人能帮我完成吗

"SELECT * FROM domainurls WHERE domaindetail_id = ?",@domain.id ,"and count IN (SELECT Max( count ) FROM domainurls WHERE domaindetail_id =?",@domain.id")"

Answer 1

这里有一种方法：

Domainurl.
  where(:domaindetail_id => @domain.id).
  where("count IN (SELECT MAX(count) FROM domainurls WHERE domaindetail_id = ? ", @domain.id)
