this.getHibernateTemplate().find(hql.toString());问题
List list= this.getHibernateTemplate().find(hql.toString());
发出SQL语句

select leg.destcode from Leg leg left join leg.flight flt where leg.destcode='HAK' and leg.tmatd <= to_date('2011-10-19 13:30','yyyy-MM-dd HH24:mi') and leg.tmatd >= to_date('2011-10-19 10:30','yyyy-MM-dd HH24:mi') order by leg.tmatd desc

然后用这句SQL语句到数据库中执行可以得到数据，但现在list里面却是“”空串，求大侠帮忙

------解决方案--------------------
把打出来的sql放在plsql执行，看看有错误没。。
debug一下看看返回的list是否真是空啊。
