Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34212

以下是导致问题的函数：

Private Sub getTimes()
    Dim strSQL3 As String = "select datetimestamp, cast(datepart(yyyy, datetimestamp) as varchar(4))  + '-' + cast(datepart(mm, datetimestamp) as varchar(2)) + '-' + cast(datepart(dd, datetimestamp) as varchar(2))  as yyyyddmm, datepart(hh,datetimestamp) * 3600 + datepart(mm,datetimestamp) * 60 as protime, datepart(hh,datetimestamp) * 3600 + datepart(mm,datetimestamp)  + 18000 as protimeplus5 from dex_racklabels.dbo.inv_master where recid = " & Session("INVID")

    Dim cnIT3 As New SqlConnection
    cnIT3.ConnectionString = ConfigurationManager.ConnectionStrings("csracklabels").ConnectionString
    cnIT3.Open()

    Dim dsTop1 As New DataSet
    Dim daTop1 As New SqlDataAdapter(strSQL3, cnIT3)
    daTop1.Fill(dsTop1)
    cnIT3.Close()

    If dsTop1.Tables(0).Rows.Count > 0 Then
        Session("intTm1") = dsTop1.Tables(0).Rows(0).Item("protime")
        Session("inttm2") = dsTop1.Tables(0).Rows(0).Item("protimeplus5")
        Session("yyyyddmm") = dsTop1.Tables(0).Rows(0).Item("yyyyddmm")
        Session("datetimestamp") = dsTop1.Tables(0).Rows(0).Item("datetimestamp")
    End If
End Sub

所以我试图谷歌这个问题，似乎总是我们将一些愚蠢的东西传递给SQL而不被认为是一种功能....但我怎么得到＆＃39; Dexsys＆＃39 ;当我在这个功能中没有这样的东西时？

此外，当我删除strSQL3并将其放入SQL并运行它...它运行正常...它可能是最后的位置？如何停止代码并在变量中显示值：Session（＆＃34; INVID＆＃34;）...我习惯于只能做response.write（Session（＆＃34; INVID＆＃34） ;））然后是response.end（）......

我已经多次遇到这个问题，并且非常想了解如何纠正它以及它为什么会发生。谢谢。

Answer 1

想出来......

1）我可以使用response.write和response.end lol ...愚蠢的我没有真正尝试过......

2）Dexsys（2015-9-16）是Session Varaible中的内容......因此内置函数的错误！

Answer 2

嗯，我猜你的问题是你的Session（＆＃34; INVID＆＃34;）你可以使用调试模式来检查Visual Studio中的变量名称，或者在调试会话中显示它

Debug.Writeline(strSQL3)
'or
Console.WriteLine(strSQL3)

您还可以在Try Catch Exception中包装该函数，以便更好地检查正在发生的错误。您还可以获取特定版本的Exception以查找更多信息。

喜欢这个

    Try
        'your code goes here.
    Catch ex As SqlException
       throw
    End Try

System.Data.SqlClient.SqlException：＆＃39;＆＃39;不是公认的内置函数名称
