Question

我收到错误：'你的SQL语法有错误;检查与您的MySQL服务器版本对应的手册，以便在'HAVING（SUM（当PTSD2E_1为空，然后1个0结束）+ SUM时使用正确的语法（在尝试运行此更新时，在第3行的PTSD2E_2'时的情况）如果少于2个缺失值，则该语句尝试使用求和行（如PTSD_Total）更新表。代码在作为SELECT运行时有效.PTSD_Total列在表中作为tinyint存在（如当前用空值填充的值很小。任何有助于发现我的错误的帮助。

    UPDATE mytablename
    SET PTSD_Total = ((SUM(IFNULL(PTSD2E_1,0)))+(SUM(IFNULL(PTSD2E_2,0)))+
(SUM(IFNULL(PTSD2E_3,0)))+(SUM(IFNULL(PTSD2E_4,0)))+
(SUM(IFNULL(PTSD2E_5,0)))+(SUM(IFNULL(PTSD2E_6,0)))+
(SUM(IFNULL(PTSD2E_7,0)))+(SUM(IFNULL(PTSD2E_8,0)))+
(SUM(IFNULL(PTSD2E_9,0)))+(SUM(IFNULL(PTSD2E_10,0))))
    HAVING (SUM(CASE WHEN PTSD2E_1 IS NULL THEN 1 ELSE 0 END)+SUM(CASE WHEN 
PTSD2E_2 IS NULL THEN 1 ELSE 0 END)+SUM(CASE WHEN PTSD2E_3 IS NULL THEN 1 
ELSE 0 END)+SUM(CASE WHEN PTSD2E_4 IS NULL THEN 1 ELSE 0 END)+SUM(CASE WHEN 
PTSD2E_5 IS NULL THEN 1 ELSE 0 END)+SUM(CASE WHEN PTSD2E_6 IS NULL THEN 1 
ELSE 0 END)+SUM(CASE WHEN PTSD2E_7 IS NULL THEN 1 ELSE 0 END)+SUM(CASE WHEN
 PTSD2E_8 IS NULL THEN 1 ELSE 0 END)+SUM(CASE WHEN PTSD2E_9 IS NULL THEN 1 
ELSE 0 END)+SUM(CASE WHEN PTSD2E_10 IS NULL THEN 1 ELSE 0 END)) < 2;

经过大量的搜索和重新排序......这有效......万一它可以帮助其他人！

    private async void Capturar_Click(object sender, RoutedEventArgs e)

    {
        SpeechRecognizer reco = new SpeechRecognizer(language);
        string[] responses = { "1", "2", "3", "4", "5", };



        var listConstraint = new Windows.Media.SpeechRecognition.SpeechRecognitionListConstraint(responses, "Comandos");

        reco.Constraints.Add(listConstraint);

        await reco.CompileConstraintsAsync();
        IAsyncOperation<SpeechRecognitionResult> op = reco.RecognizeAsync();

        reco.Timeouts.EndSilenceTimeout = TimeSpan.FromSeconds(1.2);
                op.Completed += HandleCompilationCompleted;



    }

    public async void HandleCompilationCompleted(IAsyncOperation<SpeechRecognitionResult> asyncInfo, AsyncStatus status)
    {

        var result = asyncInfo.GetResults();
        string caso = result.Text;


        if (result.Confidence != SpeechRecognitionConfidence.Rejected)
        {

            {
                string recognizedText = result.Text;

                // var dialog2 = new Windows.UI.Popups.MessageDialog(result.Text);

                // await dialog2.ShowAsync();
               resp = resp+ result.Text;
                reco.Timeouts.EndSilenceTimeout = TimeSpan.FromSeconds(1.2);
            };
            var dialog2 = new Windows.UI.Popups.MessageDialog(resp);

            await dialog2.ShowAsync();
        }
        //  }
    }

使用sum更新同一个表并且不工作
