Question

我在vn.net中有以下代码：

     Dim opdragdeleteNuloesskattings As New SqlCommand
    konneksie.ConnectionString = "Data Source=GIDEON-E-LAPTOP\SQLEXPRESS2014;Initial Catalog=SkeduleringDatabasis;Integrated Security=True"
    konneksie.Open()
    opdragdeleteNuloesskattings.Connection = konneksie
    opdragdeleteNuloesskattings.CommandText = " DELETE() " & _
         " FROM Oesskattings " & _
         " WHERE  ton_skat_tot = 0 "


    konneksie.Close()

    MsgBox("Blokke met geen oesskattings uitgevee")

我在opdragdeleteNuloesskattings.ExecuteNonQuery（）行上收到错误消息（附加信息：＆＃39;（＆＃39;）附近的语法错误。

我无法弄清楚我做错了什么。任何帮助将不胜感激。

Answer 1

self.imageManager?.requestImageForAsset(asset, targetSize: cellSize, contentMode: .AspectFill, options: nil){ result, info in if(asset.mediaType == .Video){ self.imageManager?.requestAVAssetForVideo(asset, options: nil, resultHandler: {(asset: AVAsset?, audioMix: AVAudioMix?, info: [NSObject : AnyObject]?) in let asset = asset as? AVURLAsset if asset?.URL.absoluteString != nil{ self.videoURLArray.append([indexPath.row:(asset?.URL.absoluteString)!]) } }) } cell.image = result }不是一个功能。在DELETE声明后删除()：

DELETE

Answer 2

您的查询必须

DELETE Oesskattings WHERE  ton_skat_tot = 0

vb.net sql命令无法删除
