1.hql更新   

   String hql = "update PhUser set realName=?";   

   int row=this.getSession().createQuery(hql).setString(0, "小李想").executeUpdate();   

   PhUser 类名    

2.hql删除   

   String hql = "delete PhUser a where a.userId=2";

   int row=this.getSession().createQuery(hql).executeUpdate();   

   还有个这种的格式:   

   final String hql = "delete PhRoleFunction as a where a.roleId = "  

     + roleId;   

   this.getHibernateTemplate().execute(new HibernateCallback() {   

    public Object doInHibernate(Session session)   

      throws HibernateException, SQLException {   

     return session.createQuery(hql).executeUpdate();   

    }   

   });更新也可以写成这样的格式   

3.hql单表查询   

   String hql = "from PhUser a where a.userId=" + userId;   

   List list = this.getHibernateTemplate().find(hql);   

4.hql多表查询   

   (1)String hql = "select new map(a.CUId as CUId,a.unitName as unitName,b.CUFId as CUFId,b.UFName as UFName) 

   from PhCorrelativeUnit a,PhCorrelativeUnitFunction b where a.CUId=b.CUId";   

   List list = this.getHibernateTemplate().find(hql);   

   多个表的字段放到map中,map的键值就是as后面的别名,如果没有as就是字段名   

   (2) String hql = "SELECT NEW COM.PHANTOM.APPEAL.ACTION.BEAN.DEALPAPER(A.ID AS ID, A.BILLID AS BILLID, A.STATE AS STATE, A.CREATOR AS CREATOR, A.CREATETIME AS CREATETIME , 26. B.EVENTCONTENT AS EVENTCONTENT , C.REALNAME AS REALNAME, B.BILLCODE AS BILLCODE, 27. B.CITNAME AS CITNAME ) 

  FROM PHDEALBILL A

      ,PHACCEPTBILL B

      ,PHUSER C 28.WHERE A.DEPARTMENTID="+ billid+ "

   AND A.STATE = 0

   AND A.BILLID = B.BILLID 29.AND A.CREATOR = C.USERID

 ORDER BY A.BILLID

";   

    return this.getHibernateTemplate().find(hql);   

   另外就是写一个类,对应你要查询的字段,这里的类名是new com.phantom.appeal.action.bean.DealPaper,里面对应查询的字段名   

5.得到记录数   

   String hql = "select count(*) from PhUser";   

   List list = this.getHibernateTemplate().find(hql);   

   return ((Long) list.get(0)).intValue();
