import java.util.List;

import org.hibernate.Session;

import com.tarena.sd0802.dao.StudentDao;
import com.tarena.sd0802.util.HbnUtil;

public class StudentImpl implements StudentDao {

	public int findAllRows() {
		Session s = HbnUtil.getSession();
		String hql ="from Student";
		List l = s.createQuery(hql).list();
		return l.size();
	}

	public List selectAllStudent(int currentPage,int pageSize) {
		List list =null;
		Session s = HbnUtil.getSession();
		String hql ="from Student";
		//起始位置
		int startRow = (currentPage-1)*pageSize;
		list = s.createQuery(hql)
				.setFirstResult(startRow)
				.setMaxResults(pageSize).list();
		return list;
	}
