我可以映射到这样的查询:

select id,name,address,(select count(*) from account where record_id=id ) as counter
from data where id = :id

目前,我正在使用本机SQL.

class person
{
    public virtual long Id{get;set;}
    public virtual string Name{get;set;}
    public virtual string Address{get;set;}
    public virtual long Counter{get;set;}
}

映射:

<property name="Counter" formula="(select count(*) from account where record_id=id )"      type="long"/>
