SSIS Compare 2 flat files and create a third flat file

Hey all,
I have two flat files structured as:
Flat File A:
3213,214,14,21421,354,325
Flat File B:
3213,214,14, 55,89, 21421,354,325
I am trying to create an ETL Package that compares Flat File A, to Flat File B, finds an anomaly, in this case
55,89, then outputs the anomalies to Flat File C, separated by commas.
How would I go about doing this? Everything I have looked at shows comparisons between SQL DB's.
Any suggestions?
Thank you

Hi, I'm looking for a no code solution for my clients. They're happy with drag and drop, but would prefer a no-code solution. Is this possible?
sorry what do you mean by drag and drop? what will client drag and drop? From what interface?
If you can give bigger picture then it would help
In SSIS you've to implement using SSIS tasks only
And in the above case you need to write code in any case be it script task which is in C#,VB .NET or be it execute sql task which is sql.

  • Parsing .xls(excel) file and creating a .xdat(xml) file out of it

    Hi All,
    need some tips on a task i am trying accomplish for some days now.
    I have a excel file, in which I have 10 columns with 40-50 rows of data.
    I have a xml structure in mind, in which I want to put all these data from excel file. But till now I haven't understood exactly how I should go about it step by step.
    Should I first parse the excel file and save each row (with the column names) in a list, and then read through each row and insert them in the xml format i have planned?
    And how do I open a .xdat data and tell my program to insert the data in the sequence of sets I want them to be saved?
    I know it's a pretty newbie question ... but will appreciate any help and tips provided. Would help me a lot to learn this new type of task.
    Thank you.
    with best regards,
    Newbie

    If you are using JAXB you unmarshall to read the xml. Then you marshall to write.
    So what you do is:
    1) Unmarshall your xml document. This means you now have your xml as Java objects.
    2) Read through the Java objects using loops, etc making any changes to the values. I think here you want to add values, so you can set your values
    3) Now in memory you have your new xml thats been updated, so you can marshall it (save it)
    I'd recommend a JAXB tutorial. But the basic steps are:
    1) Create an xml file and insure its valid
    2) Use a free online utility (http://www.hitsw.com/xml_utilites/) to convert the xml into an xml schema (xsd)
    3) Use xjc from the jaxb jar and run it over the xml schema (the command i use is xjc myxmlfile.xsd -p com.example
    4) Step 3 above creates all the java classes for you to use so then you can unmarshall. Process. Then marshall
    This is just a high level. I might have missed something, but the jaxb tutorial is really good and that's how I learned the process.

  • What is the best, most efficient way to read a .xls File and create a pipe-delimited .csv File?

    What is the best and most efficient way to read a .xls File and create a pipe-delimited .csv File?
    Thanks in advance for your review and am hopeful for a reply.
    ITBobbyP85

    You should have no trouble doing this in SSIS. Simply add a data flow with connection managers to an existing .xls file (excel connection manager) and a new .csv file (flat file). Add a source to the xls and destination to the csv, and set the destination
    csv parameter "delay validation" to true. Use an expression to define the name of the new .csv file.
    In the flat file connection manager, set the column delimiter to the pipe character.

  • Music and Video on Nas in folders but how do i set up itunes on multiple computers to see and use these files and create libraries?

    Music and Video on Nas in folders but how do i set up itunes on multiple computers to see and use these files and create libraries?
    So i have had a itunes set up on my old PC, bought a NAS and copied the folders over to the NAS, i did this incorrectly and so then even when i told the old PC to use that folder it saw all the songs but wasnt able to play the songs as it was looking in the incorrect place.
    So now i want my Mac as well as my PC and others to all use the music, videos etc on the NAS they are in itunes friendly folders (as they were compiled this way by the itunes on the old PC.
    When i tell the mac to use the itunes library.itl file it sees the song list (about 100gb) but cant see any songs, so i have removed this file to another location for now with the hope to set up a new file and then get it to see the songs on the folder from the NAS.
    Can someone tell me how to do this for all the Mac's and PC's on my network as i really want one master library that all use and add too.
    Thanks for your help in advance.

    I have the same question but I am using two pc's

    First of all, use [code]-tags to make your code readable, please.
    I didn't do a complete inspection of your code (because it's too much and unreadable as it is) and I don't know POI, but creating a new HSSFWorkbook for each input file sounds fishy to me ... try re-using the workbook and just creating a new sheet in each iteration.

    Andrei1,
    Thank you for the helpful advice. I made the changes as you suggested but I am receiving a #1009 error message even though my site is working the way I wan it to work. I would still like to fix the errors so that my site runs and error free. This is the error I am receiving:
    "TypeError: Error #1009: Cannot access a property or method of a null object reference."
    I'm sure this is not the best method to unload loaders and I am guessing this is why I am receiving the following error message.
         loader.unload();
         loader2.unload();
         loader3.unload();
    I also tried creating a function to unload the loader but received the same error message and my portfolio swf was not showing at all.
         function killLoad():void{
         try { loader.close(); loader2.close; loader3.close;} catch (e:*) {}
         loader.unload(); loader2.unload(); loader3.unload();
    I have a question regarding suggestion you made to set Mouse Event to "null". What does this do setting the MouseEvent do exactly?  Also, since I've set the MouseEvent to null do I also have to set the loader to null? e.g.
    ---- Here is my updated code ----
    // variable for external loaders
    var loader:Loader;
    var loader1:Loader;
    var loader2:Loader;
    var loader3:Loader;
    // makes borders resize with browser size
    function resizeHandler(event:Event):void {
    // resizes portfolio page to center
         loader.x = (stage.stageWidth - loader.width) * .5;
         loader.y = (stage.stageHeight - loader.height) * .5;
    // resizes about page to center
         loader3.x = (stage.stageWidth - 482) * .5 - 260;
         loader3.y = (stage.stageHeight - 492) * .5 - 140;
    //adds gallery.swf to stage at begining of moviie
         Down();
    //PORTFOLIO BUTTON
    //adds eventlistner so that gallery.swf can be loaded
         MovieClip(root).nav.portfolio.addEventListener(MouseEvent.MOUSE_DOWN, Down, false, 0, true);
    function Down(event:MouseEvent = null):void {
    // re adds listener for contact.swf and about.swf
         MovieClip(root).nav.info.addEventListener(MouseEvent.MOUSE_DOWN, Down1, false, 0, true);
         MovieClip(root).nav.about.addEventListener(MouseEvent.MOUSE_DOWN, Down3, false, 0, true);
    //unloads gallery.swf from enter frame if users presses portfolio button in nav
         var requester:URLRequest=new URLRequest("carouselLoader.swf");
         loader = new Loader();
         loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, ioError);

  • When I update itunes it deletes the library file, and when I restore that file from the previous libraries or my backup, itunes will run but tell me "the iTunes library file cannot be saved. A folder was specified instead of a file" How do I fix this?

    Hi there Br0x,
    You may want to try rebuilding the iTunes library as an initial troubleshooting step. Take a look at the article below for more information.

    A controlfile create is a fairly trivial task, for either a cold backup or hot backup scenario. Well, its an easy task after you've done the process a few times.
    If you have a healthy oracle instance running any place else, preferably at 11gR2, or even a 10g instance can work as an example, get a system connection and do an `alter database backup controlfile to trace;` and the instance will create a new trace file with all SQL commands needed to rebuild the controlfile in the instance trace directory.
    Have a look at the trace file, a `show parameter diag` reveals the diagnostic_dest parameter, look for the "trace" directory under that folder, for the latest *trc file. In 10g its `show parameter dump` and the trace file goes straight to the user_dump_dest directory, no digging required.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

  • Strip classes actually  used in a jar file to create a smaller jar file?

    I am creating a applet using java3d and the jar files add up to over 4meg ( j3dcore.jar j3dutils.jar vecmath.jar). Is there a way you can strip out only the classes your applet uses and create a smaller jar file so that the download isn't as big? Currently takes a long while for the applet to start because it downloads the Java 3D library in its entirety.

    Most likely those classes that you use also use other classes that you don't use ...

    disaster, thanks firefox 1 year of photos lost

    Thanks for the obvious question. I mean it. The very same thought came to me this morning and, sure enough, I had booted into another drive--my old one that, of course, had the old desktop, etc.
    It didn't dawn on me that this was the case since I hadn't set it as a boot drive but I guess in the course of all the restarts I did, it got switched.
    I'm back to normal again.
