怎样在NHibernate中执行类似的SQL语句:select max(orderNo) as result from tRole??
获取最大序号的角色#region 获取最大序号的角色
public Persistent.Role MaxOrderNoRole() { Persistent.Role result =new Role(); try { System.Collections.IList ilist = session.Find("from Role as a order by a.OrderNo desc"); if (ilist.Count !=0) { result = ilist[0] as Persistent.Role; } } finally { session.Close(); } return result; }
