批量删除的有关

//获取一个数组id
String [] ids = request.getParameterValues("sel");

//数组id作为参数传入方法
public int delMorePets(String[] ids) {

  StringBuffer sBuffer = new StringBuffer();   //new一个StringBuffer

  if (ids != null) {
                             //循环读取出数组中的id
   for (int i = 0; i < ids.length; i++) {
    sBuffer.append("'").append(ids[i]).append("',");  //给每个Id前后加单引号和一个逗号隔开
   }
  }
                    //编写sql语句   使得要被删除的记录Id in 数组id中
  String sql = "delete from PetInfo where petID in ("
    + sBuffer.substring(0, sBuffer.length() - 1) + " )";
                   //最后返回sql语句
  return this.execueSQL(sql, null);
