SSIS中的临时脚本任务错误

执行包时，我正经历一个非常奇怪的情况。由于业务需求，包中所有DFT中的派生列已由脚本任务替换。SSIS中的临时脚本任务错误

发展执行包导致该错误的语句，有时偶尔错误为“值过大而被添加到缓冲区”，有时脚本任务失败说明

System.ArgumentOutOfRangeException: Year, Month, and Day parameters describe an un-representable DateTime

The milliseconds value is out of bounds (not between 0 & 999).

处决期间接收一些其它错误消息如下所述： -

但是扭捏DefaultMaxBufferRows & DefaultMaxBufferSize财产，我成功地执行包单独或通过SQL Server的约40倍的开发和测试环境，以确保它不会再次失败后，。但生产执行再次失败，具有类似的日期特定错误。

我张贴包含在脚本的任务是在每个DFT的类似下面的代码： -

Public Class ScriptMain 
    Inherits UserComponent 
    Dim xyzArray() As String 
    Dim rowValue As String 
    Dim strDate As String 
    Dim columnxyz As String '= Me.Variables.MaterialMaster.ToString() 
    'Dim v1 As IDTSVariables100 


Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) 

    rowValue = Row.XYZtoABC.ToString() + "~".ToString() 
    xyzArray = rowValue.Split(New Char() {"~"c}) 
    strDate = Row.DateColumn.ToString() 
    columnxyz = Row.columnxyz.ToString() 
    CreateNewOutputRows() 

End Sub 

Public Sub CreateNewOutputRows() 

    ResultBuffer.AddRow() 
    ResultBuffer.xyz1 = xyzArray(1) 
    ResultBuffer.xyz2 = xyzArray(2) 
    ResultBuffer.xyz3 = xyzArray(3) 
    ResultBuffer.xyz4 = xyzArray(4) 
    ResultBuffer.xyz5 = xyzArray(5) 


    ResultBuffer.Datecolumn = CDate(strDate) 
    ResultBuffer.columnxyz = columnxyz 

End Sub 

End Class

的问题是数据有关。您偶尔会导入无法表示为日期的数据，并尝试将其输出为日期。由于您没有任何代码来解决此问题，因此您将收到错误消息。

你可以把这个线在TRY ... CATCH块，并决定如何在字符串不能转换为日期的情况下，这样做：

ResultBuffer.Datecolumn = CDate(strDate)

对于日期列，在此任务之前使用派生列通过GETDATE（）提供输入。 –

然后也许它是一个不同的列，但答案的一般点仍然是正确的。它与数据相关，偶尔会试图将值填充到无法保存的数据类型中。一种解决方案是在发生错误时使用TRY..CATCH来处理错误。 –

如果strDate有特定的格式（即："dd-MM-yyyy HH:mm:ss"）。你必须使用Date.ParseExact()功能如下所示：

ResultBuffer.Datecolumn = Date.ParseExact(strDate,"dd-MM-yyyy HH:mm:ss",System.Globalization.CultureInfo.InvariantCulture,System.Globalization.DateTimeStyles.None)

此外，如果你有很多特定的格式，你可以声明一个字符串数组并将它传递给这个函数如下所示：

dim strFormats() as string = {"dd-MM-yyyy","yyyy-MM-dd"} 
ResultBuffer.Datecolumn = Date.ParseExact(strDate,strFormats,System.Globalization.CultureInfo.InvariantCulture,System.Globalization.DateTimeStyles.None)

CDate功能有关区域设置，所以最好的做法是用Date.ParseExact

还有一点工作是使用DB_TIMESTAMP作为列类型，而不是DT_DATE

strDate在脚本任务之前通过派生列从GETDATE（）获取输入。它仍然需要使用Date.ParseExact（）？ –

@MominGoni GETDATE（）取决于SQL Server排序规则，CDATE（）取决于机器区域设置 – Yahfoufi

@MominGoni尝试使用列类型'DB_TIMESTAMP'而不是'DT_DATE' – Yahfoufi
