Question

我有一个包含阿拉伯语列名的Access 2007数据库。

我想要做的是使用整数作为主键的图像更新，但是我收到一条错误，说UPDATE语句语法中有错误。

这是相关代码

Private Sub InsertImage(ByRef barcode As Image, ByRef photo As Image, ByVal recID As String)
    Dim conn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\المشروع\April2015.accdb")
    Dim photodata As MemoryStream = New MemoryStream
    Dim barcodedata As MemoryStream = New MemoryStream
    photo.Save(photodata, ImageFormat.Png)
    barcode.Save(barcodedata, ImageFormat.Png)
    Dim photobytes() As Byte = photodata.GetBuffer()
    Dim barcodebytes() As Byte = barcodedata.GetBuffer()
    Dim query As String = _
    "UPDATE [Records] SET [الصورة] = @photo, SET [باركود] = @barcode WHERE [رقم السجل] = @recID"
    Dim cmd As OleDbCommand = New OleDbCommand(query, conn)
    Dim pParam As OleDbParameter = New OleDbParameter("@photo", OleDbType.Binary)
    pParam.Value = photobytes
    pParam.Size = photobytes.Length
    Dim bParam As OleDbParameter = New OleDbParameter("@barcode", OleDbType.Binary)
    bParam.Value = barcodebytes
    bParam.Size = barcodebytes.Length
    Dim rParam As OleDbParameter = New OleDbParameter("@recID", OleDbType.Integer)
    rParam.Value = Int32.Parse(recID)
    cmd.Parameters.Add(pParam)
    cmd.Parameters.Add(bParam)
    cmd.Parameters.Add(rParam)
    conn.Open()
    cmd.ExecuteNonQuery()
    conn.Close()
End Sub

错误详情为：

您有多个set子句，而您只需要一个，无论您要更新多少列：

UPDATE [Records] 
SET    [الصورة] = @photo, [باركود] = @barcode 
WHERE  [رقم السجل] = @recID

带有阿拉伯语列名的update语句中的语法错误
