You may run into a case where working with old data can cause issues downstream. Now, you can use ActiveX to check the age of a file before proceeding. The code assumes that you have already assigned the file location elsewhere in the DTS Package. The code also assumes that you want to raise an error if the file is older than 24 hours.
Here is the code:
Option Explicit
Function Main()
Dim oFSO, oConn, sFileName, oFile
' Get the filename from my Text File connection called "Text File (Source)"
' There are other ways to do this, of course.
Set oConn = DTSGlobalVariables.Parent.Connections("Text File (Source)")
sFilename = oConn.DataSource
Set oConn = Nothing
Set oFSO = CreateObject("Scripting.FileSystemObject")
' Check File Exists first
If Not oFSO.FileExists(sFilename) Then
' Return Error
Main = DTSTaskExecResult_Failure
Else
' Get file object
Set oFile = oFSO.GetFile(sFilename)
' Check age of file is less than 24 hours
If DateDiff("h", oFile.DateLastModified, Now) <= 24 Then
' Return Error
Main = DTSTaskExecResult_Failure
Else
' Return Success
Main = DTSTaskExecResult_Success
End If
End If
Set oFile = Nothing
Set oFSO = Nothing
End Function
You now know if the file is older than 24 hours ago.
