            {
                return new List<Seller>();
            }
            string hql = @"select distinct s
                           from Seller s 
                           where  s.Deleted = false 
                                  and ( s.Email like '%:searchKeyWords%')";

            SimpleQuery<Seller> q = new SimpleQuery<Seller>(hql);
            q.SetParameter("searchKeyWords", searchKeyWords);
            return q.Execute().ToList();
        }

推荐答案

为什么不通过参数传递％字符?

Why do not u pass the % character with parameter?

   string hql = @"select distinct s
                           from Seller s 
                           where  s.Deleted = false 
                                  and ( s.Email like :searchKeyWords)";
   SimpleQuery<Seller> q = new SimpleQuery<Seller>(hql);
   q.SetParameter("searchKeyWords", "%"+searchKeyWords+"%");
   return q.Execute().ToList();
