NHibernate & Spring.NET关联查询问题

CREATE TABLE t_log
(
  fid identity(int,1,1),
  fuserid varchar(50),
  fip varchar(50),
  fmac varchar(50),
  ftime datetime,
  ftype integer,
  fdbid varchar(50),
  ffldid varchar(50),
  foperate varchar(50),
  flevel integer,
  fremark varchar(50)
)

CREATE TABLE t_reltype
(
  fid identity(int,1,1),
  ftablename varchar(50),
  ffieldid varchar(50),
  ftype integer,
  fname varchar(50)
)

其中ftype与表t_reltype关联
现需在UI界面显示数据列表，需要将两个表进行关联查询
如：select t.*,q.fname as cn_type from t_log as a left join t_reltype as q on t.ftype=q.ftype and q.ftablename='t_log' where fid>10 order by t.fid desc

这种问题在NHibernate中如何解决？利用一对多，多对多，多对一处理？？
