SSIS-如何在脚本任务中访问RecordSet变量

问题描述

如何在脚本任务中访问RecordSet变量?

How do you access a RecordSet variable inside a Script Task?

推荐答案

在脚本选项卡上，确保将变量放在readonlyvariables或readwritevariables文本框中.

On the script tab, make sure you put the variable in either the readonlyvariables or readwritevariables text boxes.

这是一个简单的脚本，用于将数据流中的错误(保存在RecordSet变量中)格式化为电子邮件正文.基本上，我将记录集varialbe读入数据表，并使用for循环逐行处理它.完成此任务后，我将检查uvErrorEmailNeeded的值，以确定是否可以使用条件流程连接器发送电子邮件.您还需要在vb脚本中添加对system.xml的引用.这是在SQL 2005中.

Here is a simple script that I use to format the errors in a data flow (saved in a RecordSet Variable) into the body of an email. Basically I read the recordset varialbe into a datatable and process it row by row with the for loops. After this task completes I examine the value of uvErrorEmailNeeded to determine if there is anything to email using a conditional process flow connector. You will also need to add a reference to system.xml in your vb script. This is in SQL 2005.

Public Class ScriptMain


    Public Sub Main()


        Dim oleDA As New OleDbDataAdapter
        Dim dt As New DataTable
        Dim col As DataColumn
        Dim row As DataRow
        Dim sMsg As String
        Dim sHeader As String


        oleDA.Fill(dt, Dts.Variables("uvErrorTable").Value)
        If dt.Rows.Count > 0 Then
            Dts.Variables("uvErrorEmailNeeded").Value = True
            For Each col In dt.Columns
                sHeader = sHeader & col.ColumnName & vbTab
            Next
            sHeader = sHeader & vbCrLf
            For Each row In dt.Rows
                For Each col In dt.Columns
                    sMsg = sMsg & row(col.Ordinal).ToString & vbTab
                Next
                sMsg = sMsg & vbCrLf
            Next
            Dts.Variables("uvMessageBody").Value = "Error task. Error list follows:" & vbCrLf & sHeader & sMsg & vbCrLf & vbCrLf
        End If

        Dts.TaskResult = Dts.Results.Success
    End Sub

End Class
