SSIS - How to access a RecordSet variable inside a Script Task

Question

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

Answer 1

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

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
