Question

我想添加多个数据，是否有更快的方式。

我的意思是系统的速度。

感谢

    Dim table = Dt
    Dim strSqlInsert As String = ""

    If table.Rows.Count > 0 Then
        For i As Integer = 0 To table.Rows.Count - 1
           strSqlInsert += "INSERT INTO " & TableName & " VALUES ('" & Convert.ToString(table.Rows(i)("Name")) & "' , " & Convert.ToString(table.Rows(i)("Number")) & ") ; "
        Next
    End If

    Dim conn As SqlConnection = New SqlConnection(Web.Configuration.WebConfigurationManager.ConnectionStrings.Item("ConnectionString").ConnectionString)
    Dim cmd As New SqlCommand(strSqlInsert, conn)

    Dim odt As SqlTransaction = Nothing
    odt = conn.BeginTransaction(IsolationLevel.ReadUncommitted)
    cmd.Transaction = odt

    Try
        cmd.ExecuteNonQuery()
        odt.Commit()
    Catch ex As SqlException
        odt.Rollback()
        Response.Write(ex.ToString())
    Finally
        If cmd IsNot Nothing Then
            cmd.Dispose()
        End If
        If odt IsNot Nothing Then
            odt.Dispose()
            odt = Nothing
        End If
        If conn.State = ConnectionState.Open Then
            conn.Close()
        End If
        conn.Dispose()
    End Try

Answer 1

输入多个数据的最佳方法是使用XML。将xml文件传递给存储过程到DB并通过sp插入而不是代码中的内联查询。你可以看到完整example here

Answer 2

在前端，创建一个DataTable并将要插入的记录添加到DataTable中。然后执行以下步骤：

  DataSet ds = new DataSet();
  dt.TableName = "AddTable";        //dt is the DataTable you have Created to Insert
  ds.Tables.Add(dt);

将此DataSet作为参数传递给Insert SP，如

 ds.GetXml();

此方法将以更快的方式插入记录。
