SSIS - Dynamically moving Files to Folder with Matching Substring Name

问题

I'm using a foreach loop and file system task to move files into specific folders (or trying to at least).

i.e.

A file name can be 100000 and it needs to go to folder 1000 File 102000 needs to go to folder 1020 File 103000 need to go to folder 1030 etc etc

I'm struggling with how to move the files to the correct folder.

I thought I could use a variable with the upper level directory followed by a substring of the filename variable held in the foreach loop

e.g.

"D:\\Archive\\" + SUBSTRING(@[USER::Variable],1,4)

But that doesn't work and I get an error that the path format is not supported.

Any help is greatly appreciated, thanks.

Your issue

First of all,I think the error is because the variable contains the fullpath not only the filename so you have to use a similar expression:

"D:\\Archive\\" + LEFT(RIGHT( @[User::Variable] , FINDSTRING(REVERSE( @[User::Variable] ) , "\\", 1) - 1),4)

Detailed Solutions

First Method - Using script Task

Try using a script task to achieve this, Just select your variable as a ReadOnlyVariable in the Script Task. and use a similar script (I Used Vb.net)

Public Sub Main()

    Dim strFile As String = Dts.Variables.Item("User::Variable").ToString

    Dim strFilename As String = IO.Path.GetFileName(strFile)


    'Create Directory
    If Not IO.Directory.Exists("D:\Archive\" & strFilename.Substring(0, 4)) Then
        IO.Directory.CreateDirectory("D:\Archive\" & strFilename.Substring(0, 4))
    End If

    'Copy File to destination
    IO.File.Copy(strFile, "D:\Archive\" & strFilename.Substring(0, 4) & "\" & strFilename)

    Dts.TaskResult = ScriptResults.Success
End Sub

Second Method - Using File System Task

Create a new Variable @[User::DestinationPath] and set it's property Evaluate As Expression = True, then use the following expression for it:

"D:\\Archive\\" + LEFT(RIGHT( @[User::Variable] , FINDSTRING(REVERSE( @[User::Variable] ) , "\\", 1) - 1),4)
