.net - 将数据从 Access 数据库传输到 SQL Server

Question

我正在尝试将一些数据字符串从我的 Access 2010 数据传输到我在 Access 2010 中的 SQL 服务器。我不知道如何去做，也不知道 SQL 语句会是什么样子，无论是我应该打开两个数据库或什么。将给予一些指导。

Answer 1

我发现我可以打开数据库，然后打开 SQL Server。拉出记录，然后同时关闭它们。

数据库连接.Open()

    'SQL statement for find the records that need to be transfered.
    Dim SQLCommand2 As New OleDbCommand("SELECT * FROM b_forte WHERE BaleLine = '" & stBaleLine & "' and ProdDate > #" & GlobalVariables.dtLastBaleDateTime & "#", DatabaseConnection)
    Dim TransferRecord As OleDbDataReader = SQLCommand2.ExecuteReader()
    If ApplicationPropertiesWindow.DisplayCodechkbx.Checked = True Then
        MainTextBox.AppendText(Environment.NewLine & "SELECT * FROM b_forte WHERE BaleLine = '" & stBaleLine & "' and ProdDate > #" & GlobalVariables.dtLastBaleDateTime & "#")
        GlobalVariables.DisplayCode = True
    End If
    Do While TransferRecord.Read()
        ProdDate = TransferRecord.Item("ProdDate")
        BaleLine = TransferRecord.Item("BaleLine")
        If BaleLine = "A" Then
            BaleLineNum = "1"
        Else
            BaleLineNum = "2"
        End If
        BaleNumber = TransferRecord.Item("BaleNumber")
        GrossWeight = TransferRecord.Item("GrossWeight")
        AirDry = TransferRecord.Item("AirDry")
        InvoiceWeight = TransferRecord.Item("InvoiceWeight")
        'Start of writing to the SQL server.
