SSIS File System Task - Rename File

  • I have a file, test.txt that I want to copy/rename in a backup directory.

    I have created the following User variables within my SSIS package:

    Src_File = c:\test.txt

    Dest_File = test

    Dest_Dir = c:\backup

    DelayValidation = True

    I also created an Expression within the File System Task for the Destination:

    @[Dest_Dir] + "\\" + @[Dest_File] + "_" + (DT_WSTR,4)DatePart("yyyy", GetDate()) + RIGHT("0" + (DT_WSTR,2)DatePart("mm", GetDate()), 2) + RIGHT("0" + (DT_WSTR,2)DatePart("dd", GetDate()), 2) + RIGHT("0" + (DT_WSTR,2)DatePart("hh", GetDate()), 2) + RIGHT("0" + (DT_WSTR,2)DatePart("mi", GetDate()), 2) + ".txt"

    which gives me the following evaluation value: c:\test\test_200904202005.txt

    When I go to debug, the package fails, and thows out the following error:

    Error: Failed to lock variable "c:\test\test_200904202009.txt" for read access with error 0xC0010001 "The variable cannot be found. This occurs when an attempt is made to retrieve a variable from the Variables collection on a container during execution of the package, and the variable is not there. The variable name may have changed or the variable is not being created.".

    I have been to a number of forums without any advice that has resolved this issue. Is there a bug within SSIS that won't allow you to concatenate a datetime stamp to a string variable? Or am I missing something very rudementary? This should not be this difficult. Any help would be highy appreciated.

  • Can you confirm the scope of your variables?

    If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

  • There in the base package.

  • That is not what I mean. If you right click white space in the control flow window and select Variables, a list will be displayed. Column 1 is variable name, column 2 is Scope - that is what I want to know.

    If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

  • To resolve this issue , I'll suggest the following:

    Create a destination variable e.g Dest_Var

    Set its EvaluateAsExpression to "True", and copy and paste the expression you created above into the variable's Expression property

    For the File System Task:

    Set its IsDestinationPathVariable property to "True"

    Set its DestinationVariable propety to the destination variable you created

    (usually in the format-scope::Dest_Var)

    Set its IsSourcePathVariable property to "True"

    Set its SourceVariable property to the source variable you created

    (usually in the format-scope::Src_File)

    And finally, delete

    DelayValidation = True, and the

    Destination property you've set in the Expressions tab.

    I hope this helps.

    Cheers!

  • can you please clarify this bit of your instructions:

    And finally, delete

    DelayValidation = True, and the

    Destination property you've set in the Expressions tab.

    Thanks

  • I'm just tossing this out as a suggestion only because the file system task seems a bit finicky with me. Why not use a script task to rename the file. I seem to have much better luck with that task.

  • I had the same problem, and a co-worker figured out what I was doing wrong.

    After you set the IsDestinationPathVariable to True, your variable name goes directly into next property DestinationVariable.

    Do NOT (as you might in some other types of tasks) open the Expressions dialog and set it there. If you do, it will treat your destination file name as the variable name.

    See in the error message where it says it can't lock the variable 'C:\...' ? That's not a variable name, it's the value of it.

  • Thanks ehuhn, that fixed my problem.
