// 获取记录总数
recordCount = Convert.ToInt32(criteria.SetProjection( Projections.Count(MovieUrl.__ID )) .UniqueResult(  ));

criteria.SetProjection(  null  );

Criteria c = session.createCriteria(Book. class );

c.add(Restrictions.like( " bookname " ,  " a " ,MatchMode.ANYWHERE));

c.add(Restrictions.between( " bid " ,  1 ,  3 ));

c.add(Restrictions.not(Restrictions.in( " bid " ,  new  Integer[] {1,2,4} )));

c.setFirstResult( 0 );     

c.setMaxResults( 2 );    

List list = c.list();

Restrictions.like(“”,…,MatchMode.ANYWHERE)

AddOrder(Order.asc(“fwid”))

在oracle数据库中，如果使用Restrictions.ne("name","张三")，不会包括该字段值为空的记录
