Hibernate查询为何生成两条SQL语句

String hql="from News a where a.title like ?";
Query q=session.createQuery(hql);

q.setParameter(0, "%"+newstitle+"%");
newslist=q.list();

我在ACTION中执行以上查询，在MYECLIPSE中的窗口为何看到生成了两条相关的SQL语句：如下：
Hibernate: select news0_.id as id2_, news0_.title as title2_, news0_.detail as detail2_, news0_.author as author2_, news0_.bfrq as bfrq2_, news0_.newszt as newszt2_ from news news0_ where news0_.title like ?
Hibernate: select news0_.id as id2_, news0_.title as title2_, news0_.detail as detail2_, news0_.author as author2_, news0_.bfrq as bfrq2_, news0_.newszt as newszt2_ from news news0_ where news0_.title like ?


以上情况，在只找到一条记录的时候也一样，何解！

顶起，，，，，，

调用了两次？

Tips: 把日志调到 DEBUG 级别能看到更多
