servlet里：

pst = DBUtil.getPst(conn,"delete from EmpInfo where num = ?");
pst.setString(1, df[i]);
result = pst.executeUpdate();
}
if(result > 0){
response.sendRedirect("employee_list.jsp");
}else{
request.setAttribute("errmsg", "删除数据失败");
request.getRequestDispatcher("error.jsp").forward(request, response);
