SSIS 中的错误处理

Question

我创建了一个 SSIS 包，它从文件夹中获取 XML 文件并检查模式，如果模式失败，包会记录错误并将文件移动到错误文件夹。目前，我已经完成了所有要求，并且工作正常，除了我在执行结束时收到的错误消息。

验证 XML 文件

我收到的错误消息

我收到的错误消息

该软件包按预期工作正常。我怎样才能抑制这个错误信息？

更新#1：

这是我的错误历史记录

这是我的 XML 架构验证任务属性。

问题可能是由 FailPackageOnFailure 和 FailParentOnFailure 属性引起的。单击 Validate XML 任务并在“属性”选项卡中更改这些属性值。在 Control Flow 中，转到属性并更改 MaximumErrorCount 值并使其大于 1。

使用脚本任务解决方法

将 3 个变量添加到您的包中：

@[User::XmlPath] Type: String, Description: Store the Xml File Path
@[User:XsdPath] Type: String, Description: Store the Xsd File Path
@[User:IsValidated] Type: Boolean, Description: Store the result of Xml validation

添加脚本任务，select XmlPath 和 User:XsdPath 作为只读变量，IsValidated 作为读写变量
将脚本语言设置为 Visual Basic

在脚本编辑器中编写以下代码（这是整个脚本任务代码）

#Region "Imports"
Imports System
Imports System.Collections.Generic
Imports System.Data
Imports System.Math
Imports System.Text
Imports System.Xml
Imports System.Xml.Schema
Imports Microsoft.SqlServer.Dts.Runtime
#End Region

<Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute()>
<System.CLSCompliantAttribute(False)>
Partial Public Class ScriptMain
    Inherits Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase

    Enum ScriptResults
        Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success
        Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
    End Enum

    Public Function LoadXml(xmlFilePath As String, xsdFilePath As String) As Boolean
        Dim settings As New XmlReaderSettings()
        settings.Schemas.Add(Nothing, xsdFilePath)
        settings.ValidationType = ValidationType.Schema
        Dim errorBuilder As New XmlValidationErrorBuilder()
        AddHandler settings.ValidationEventHandler, New ValidationEventHandler(AddressOf errorBuilder.ValidationEventHandler)
        Dim reader As XmlReader = XmlReader.Create(xmlFilePath, settings)
        ' Read the document...
        Dim errorsText As String = errorBuilder.GetErrors()
        If errorsText IsNot Nothing Then
            Return False
        Else
            Return True
        End If
    End Function

    Public Sub Main()

        Dts.Variables("IsValidated").Value = LoadXml(Dts.Variables("XmlPath").Value.ToString, Dts.Variables("XsdPath").Value.ToString)

        Dts.TaskResult = ScriptResults.Success
    End Sub


End Class

Public Class XmlValidationErrorBuilder
    Private _errors As New List(Of ValidationEventArgs)()

    Public Sub ValidationEventHandler(ByVal sender As Object, ByVal args As ValidationEventArgs)
        If args.Severity = XmlSeverityType.Error Then
            _errors.Add(args)
        End If
    End Sub

    Public Function GetErrors() As String
        If _errors.Count <> 0 Then
            Dim builder As New StringBuilder()
            builder.Append("The following ")
            builder.Append(_errors.Count.ToString())
            builder.AppendLine(" error(s) were found while validating the XML document against the XSD:")
            For Each i As ValidationEventArgs In _errors
                builder.Append("* ")
                builder.AppendLine(i.Message)
            Next
            Return builder.ToString()
        Else
            Return Nothing
        End If
    End Function
End Class

将优先约束与表达式结合使用来处理验证成功和失败的情况
