Text File From Multiple Query Results

SQL Server 2018 R2
I need to create a text file to send to another company. The file contains 4 main parts: File Header, Master Records, Record Details and File Footer. There can be multiple Master Records and multiple Record Details associated with each Master Record.
The file should look something like this:
File Header
Master Record
Record Details
Record Details
Master Record
Record Details
Master Record
Record Details
Record Details
Record Details
File Footer
Each line type contains multiple columns that need to be separated with a “|” symbol.
I can write the queries that will return each record type in the correct order by using a loop. However I don’t know how to get them into a single text file in that order.
Please avoid solutions that use xml unless it properly takes into account the possibility of special symbols in my data.
Any help would be appreciated.

Thanks for the reply.
I had considered your solution already and found an article explaining the same thing. The problem with it is that I would somehow have to create a loop that would create and combine the files in the right order instead of just three files in a set order.
That is beyond my current knowledge.
I have found a messy way of combining all the record types into a single query in the correct order. Using that I should be able to easily export it into a text file. I don't really like my solution but it should work.
Thanks,
Scott

  • 'No Upload Authorization' While Uploading a Text File from Multiple Select

    Hi all,
       The User is trying to upload a text file from Multiple Selection screen of a Query in BEx and it gives the error message of 'No Upload Authorization' (Error DB886).
       In 'Logon data' tab of Tcode SU01, it has 'User' for 'User Group for Authorization check' for this User.
       I could upload a text file from Multiple Selection screen with my User Id.
       An idea about this error, PLEASE ?

  • Generate an xml file from Database query results

    Hi, can anyone help me out with this problem I'm having. What are the steps in creating an xml file directly from the results of a database query. I currently have a very simply process that queries a database via a partner link. The query returns the data but it's from this point that I am stuck. I need to create an xml file with the data along with the xml tags. I've looked at dozens of tutorials with no luck.
    I would greatly appreciate help with this.
    bpel rookie

    Should be quite simple.
    Create another partnerlink, configure it to use the file adapter, and write to an XML file. In this case you need to create an XML Schema (.xsd) of the file you want to create.
    Before you write to the file, either add assign steps to copy individual attributes or use a transform activity to convert from the database format to the file (xml) format.

  • Uploading a text file from webi filter area as part of the query condition

    Post Author: balasura
    CA Forum: Publishing
    Requirement : Uploading a text file from webi filter area as part of the query condition Hi, I am in a serious requirement which I am not sure available in BO XI. Can some one help me plz. I am using BO XI R2, webi I am generating a ad-hoc report, when I want to give a filter condition for a report, the condition should be uploaded from a .txt file. In the current scenario we have LOV, but LOV could hold only a small number of value, my requirement is just like a lov but the list of values will be available in a text file ( which could number to 2000 or 2500 rows). I would like to upload this 2500 values in the form of a flat text file to make a query and genrate report. Is it possible in BO XI? For Eg:- Select * from Shipment Where u201CShipment id = u2018SC4539u2019 or Shipment id = u2018SC4598u2019u201D The u201Cwhereu201D condition (filter) which has shipment id will be available in a text file and it needs to be loaded in the form of .txt file so that it will be part of the filter condition. Content of a .txt file could be this shipment.txt =============== SC4539 sc2034 SC2343 SC3892 . . . . etc upto 2500 shipment Ids I will be very glad if some could provide me a solution. Thanks in advance. - Bala

  • Producing text file from PL/SQL procedure (UTL_FILE)?

    Hi,
    I need to produce a text file from a PL/SQL procedure. My output should be a little over 38K records and my query has 70 fields. I'd like to separate the fields by pipe delimiters in the text file. I can either concatenate all 70 fields into one variable for each record or send all 70 fields over with a pipe, whichever is easier. It looks like I can't spool within PL/SQL but UTL_FILE might be an option from what I'm reading. Does anyone have any good, simple example(s) to produce a text file using this package in calling multiple fields from a LOOP? Our os is UNIX and db is Oracle 9i.
    Also, I've read that UTL_FILE has a record output of 1,023 bytes. Is this for each record line or the whole file size? I belive the max # of characters for each line wouldn't exceed 500 characters. The 38K rows I have for the data set would be well over 1MB. If this is the case, is there a work around to produce a larger text file?
    Any suggestions and/or examples would be greatly appreciated.
    Thanks,
    Eric

    Assuming the goal is to create a text file on the database server, you can use UTL_FILE here. Each line can be 1023 characters, but you can have as many lines as you'd like.
    Tom Kyte has an example here

  • How to create a pdf file from multiple images ?

    Dear All,
    I want to create a SINGLE page pdf file from two or more page size images that are combined to make a single page pdf. Again, this question is on pdfs that are made out of several, atleast  two color images and a black-and-white mask for one of them.
    I have such pdf files from an unknown source (the producer is edited out) whereby there are three tiff images, obtained using the well known pdfimages extractor.
    When I want to make a pdf out of tiff or png or other image formats, I right click and tell Adobe Acrobat to make a pdf.
    However, I dont know how I can give a command to select say,  three tif images and specify which is the mask for which and then join  them in a way that I get the pdf from the composite of the two color images and a mask for one of them.
    Please help me out.
    I am a little familiar with the pdf structure skeleton and when necessary, fixed xref tables in one of my favorite editors. A few years ago, I also wrote a bunch of javascripts to make some annotations and needed some automation and used some itext type libraries. However, I need your help in this problem as I am now rusty and forgot some of what I studied to solve my earlier problems. This is a new problem for me. Gentle hints from you would be very nice to help me in this problem. Please specify if necessary what manual and pages to read. in the pdfspec.

    I would gladly mention that I am working on windows platform, preferably XP.
    I can also work on linux for free products that come with it.

    But adding other products, for the help of an adobe products user,
    even if it outside adobe, shall add greater prestige to your company

    Well, just add the few pdf stanzas since you are proficient on it and
    I am presently a little rusty as I mentioned. Just asking a little
    extra yard, not even to go an extra mile.

    Well, ascii format or uncompressed format that is human readable. I
    know its a binary file, but human readable ascii version of it.
    I hope you can give me some stanza and various other approaches
    possible so I can select or combine things for myself. I see only a
    miniscule number of posts claiming to have written masks in this forum
    and then with no details.

    Use <b>GUI_DOWNLOAD</b> to download data in a file on the presentation server or use <b>OPEN DATASET, TRANSFER</b> and <b>CLOSE DATASET</b> statements to download data to the application server.
    Now, I hope the code for data fetching, if required, is already present in the report.
    Reward points if the answer is helpful.
    Regards,
    Mukul

  • Reading and writing to a text file from an Applet

    I'm a novice java programming with very little formal programming training. I've pieced together enough knowledge to do what I've wanted to do so far...
    However, I've been unable to figure out how to read and write to a text file from an Applet (I can do it from a normal java program just fine). Here is a simple example of what I'd like to do (you can also look at it on my website: www.stat.colostate.edu/~leach/test02/test02.html). I know that there is some problem with permission/security but I'm not smart enough to understand what the error messages are telling or understand the few books I have. If anyone can tell me how to get this applet to work, or direct me to some referrences that would help me out I'd really appreciate it.
    Thanks,
    Andy
    import java.applet.Applet;
    import java.net.*;
    import java.awt.*;
    import java.awt.event.*;
    import java.util.*;
    import java.io.*;
    public class test02 extends Applet {
    public Button B_go;
    public GridBagConstraints c;
    public void init() {
    this.setLayout(new GridBagLayout());
    c = new GridBagConstraints();
    c.fill = GridBagConstraints.BOTH;
    B_go = new Button("GO");
    c.gridx=1; c.gridy=0; c.gridwidth=1; c.gridheight=1;
    c.weightx = c.weighty = 0.0;
    B_go.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
    setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
    print_stuff();
    setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
    this.add(B_go,c);
    public static void print_stuff() {
    try{
    File f = new File("test02.txt");
    PrintWriter out = new PrintWriter(new FileWriter(f));
    out.print("This is test02.txt");
    out.close();
    }catch(IOException e){**/}
    }

    I have almost the exact same problem, and I am in the same situation as you are with respects to the language.
    I am simply trying to create a file and output some garbage to it but my applet always spits back a security violation. I've tried eliminating the restrictions on the applet runner I use but I still get the error.
    My method:
    debug = new Label() ;
    debug.setLocation( 20, 20 ) ;
    debug.setSize( 500, 15 ) ;
    add( debug ) ;
    // output
    try
         OutputStream file = new FileOutputStream( new File( "" + getCodeBase() + "output.txt" ) ) ;
         byte[] buffer = { 1, 2, 3, 4, 5 } ;
         file.write( buffer ) ;
         file.close() ;
    } catch( Exception e )
         debug.setText( e.toString() ) ;
         Can anyone tell why this isnt working?

  • How to download a text file from the server

    hi everyone,
    can anyone tell me how to download and read a text file from the server and saved in into resource folder.
    with regards
    pallavi

    its really easy
    To read from server, use something like:
    HttpConnection connector = null;
    InputStream inp_stream = null;
    OutputStream out_stream = null;
    void CloseConnection()
         if(inp_stream!=null)inp_stream.close();
         inp_stream=null;
         if(out_stream!=null)out_stream.close();
         out_stream=null;
         connector.close();
         connector = null;
    public void getResponse(String URL,String params)
      try
         if(connector==null)connector = (HttpConnection)Connector.open(URL);//URL of your text file / php script
         connector.setRequestMethod(HttpConnection.POST);
         connector.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.1");
         connector.setRequestProperty("content-type", "application/x-www-form-urlencoded");
         //connector.setRequestProperty("charset","windows-1251");
         //*** If you need to send ("arg1=value&arg2=value") arguments to script use this:
         out_stream = connector.openOutputStream();
         byte postmsg[] = params.getBytes();
         out_stream.write(postmsg);
         int rc = connector.getResponseCode();//in any case here connection will be opened & closed
         if (rc != HttpConnection.HTTP_OK)
              CloseConnection();
              throw new IOException("HTTP response code: " + rc);
         inp_stream = connector.openInputStream();
         int pack_len = inp_stream.available();
         byte answ[]=new byte[pack_len];
         inp_stream.read(answ);
         CloseConnection();
         ProcAnswer(answ);//process received data
      catch(Exception ex)
         System.err.println("ERROR IN getResponse(): "+ex);
    } And you can read from resource file like
    public void loadFile(String filename)
        DataInputStream dis = new DataInputStream(getClass().getResourceAsStream("/"+filename));
        String str="";
        try
             while (true)
                ch = dis.read();//read character
                if(ch=='\r')continue;//if file made in windows
                if(ch=='\n' || ch==-1)//end of line or end of file
                    if(str.length()==0)continue;//if empty line
                    //do some thing with "str"
                    if(ch==-1)break;//it was last line
                    str="";//next line
                    continue;
                 str+=(char)ch;
           dis.close();
       catch (Exception e)
           System.err.println("ERROR in loadFile() " + e);
    }Welcome! =)

  • How do I move text files from my desktop to my iPod Touch?

    How do I transfer (export) text files from my Mac (word processor files) to the Notes app on my iPod?

    I am going to assume that I can move individual profiles, or even delete profiles that I no longer need.
    Just be aware that if you delete or don't move profiles that are currently assigned to images LR will (without warning) reassign those images with the Adobe Standard profile.
    You can use AnyFilter, Data Explorer, or DevMeta plugins to determine if any images are assigned to a profile you want to delete. You can then reassign the profile of your choice. Once that's completed you can safely delete the camera profile.

  • Loading a text file from a relative location in shockwave

    Hi all
    I'm REALLY sorry I have to post about such an inane problem.
    I've googled this and looked in forums and found several
    suggestions but none of them are working for me. I want to load a
    text file from the same directory as my movie. I can get this
    working in authoring mode, in a projector, and in a shockwave movie
    on the local machine (using getNetText("/text.txt")).
    But when i put the shockwave movie on a server, it does NOT
    work. The macromedia documentation says that getNetText works with
    relative URLs. But when I put in the full URL, it does work, so
    obviously the shockwave movie is having a problem finding the text
    file which IS in the same directory as it.
    Any suggestions / ideas? All i want to do is access a text
    file :)
    Sorry again for such a lame problem
    Mike

    thanks - this worked. I also had to not use a repeat loop to
    wait for netDone() to return true.
    Thanks again
    MIke
