  三套路增刪改

  Code

   using SystemDataSqlClient;

  

               SqlConnection conn = new SqlConnection(xxx);

  

  

               string sql = xxx;

  

               SqlCommand comm = new SqlCommand(sql conn);

  

               connOpen();

  

               commExecuteNonQuery();

  

               connClose();

  三套路查(綁定到DataGridView

  Code

   using SystemDataSqlClient;

  

               SqlConnection conn = new SqlConnection(xxx);

  

               string sql = xxx;

  

               SqlDataAdapter da = new SqlDataAdapter(sql conn);

  

               DataSet ds = new DataSet();

  

               daFill(ds);

  

               dataGridViewDataSource = dsTables[];

  

     //要更新 查詢語句要 查詢主鍵列

  

               SqlCommandBuilder sd = new SqlCommandBuilder(da);

  

               daUpdate(dsTables[]);

  三套路查(綁定到ListView)

  代碼

  using SystemDataSqlClient;

  SqlConnection conn = new SqlConnection(xxx);

  string sql = xx;

  SqlCommand comm = new SqlCommand(sql conn);

  connOpen();

  SqlDataReader read = commExecuteReader();

  while (readRead())

  {

  ListViewItem lvi = new ListViewItem(read[xxx]ToString());

  lviTag = read[id];

  listViewItemsAdd(lvi);

  lviSubItemsAddRange(new String[] { read[xxx]ToString() });

  }

  readClose();

  connClose();
