public List<Dept> findByDeptNameAndId(int id, String name,int page ,int rowsPerPage) {
        int item = (page-1)*rowsPerPage;
        String sql = "select top "+rowsPerPage+"  * from dept where id not in(select top "+item+" id from dept)";
        if(id!=0){
            sql+=" and id like '%"+id+"%'";
        }
        if(name !=null && (name.equals("")==false)){
            sql+=" and name like '%"+name+"%'";
        }

page代表当前页面，rowsPerPage表示每页几行，我知道是SQL语句有问题，不管我page怎么改变值，它总是输出头几个rowsPerPage的记录，sql语句不太懂，研究好久了，没搞出来，请教下大家，谢谢
