listview中数据读入数据库表中，怎么没反应啊？
SqlConnection XX=new SqlConnection(Xintong);
  int Lh = listView1.Items.Count;
  for (int j = 0; j < Lh; j++)
  {
  XX.Open();

  String num = listView1.Items[j].SubItems[0].ToString();
  String name = listView1.Items[j].SubItems[1].ToString();
  String price = listView1.Items[j].SubItems[2].ToString();
  String date = listView1.Items[j].SubItems[3].ToString();
  String count = listView1.Items[j].SubItems[4].ToString();
  String ch = listView1.Items[j].SubItems[5].ToString();

  String Xql = "insert into 商品查询表 values('" + num + "','" + name + "','" + price + "','" + date + "','" + count + "','" + ch + "')";
  SqlCommand XXcom = new SqlCommand(Xql, XX);
  XX.Close();
  }
我哪些错了？

------解决方案--------------------
少了一句执行语句
XXcom.ExcuteNOQuery()
