• Need help: UTL_FILE read and write in the text file

  Hello, I'm on version 11 GR 2 by using the UTL_FILE function to read a text file and then write the lines where it starts with the word "foo" and put an end to my writing in the text file where the line with the word "ZEN". Now I have several lines that begin with 'foo' and 'ZEN' allow a paragraph, and in this paragraph, there is a line that begins with "DE4.2". Therefore,.
  I need to write all of the paragraphs that include the "DE4.2" line in their beginning and end of lines 'foo' and 'ZEN '.
  
  FOR EXAMPLE:
  
  FOO/234E53LLID
  IT'S MY SECOND LINE
  IT'S MY THIRD LINE
  DE4.2 IT OF MY FOURTH LINE
  IT'S MY FIFTH LINE
  ZEN/DING3434343
  
  FOO/234E53LLID
  IT'S MY SECOND LINE
  IT'S MY THIRD LINE
  IT'S MY FIFTH LINE
  ZEN/DING3434343
  
  I'm only interested in writing the first paragraph tha includes line DE4.2 in one of the paragraph of lines not the second ther that does not include the "DE4.2".
  
  Here is my code so far:
  
  CREATE OR REPLACE PROCEDURE my_app2 IS
  Utl_file.file_type INFILE;
  outfile utl_file.file_type;
  buffer VARCHAR2 (30000);
  b_paragraph_started BOOLEAN: = FALSE; -flag to indicate which required paragraph is started
  
  BEGIN
  -Open a file to read
  INFILE: = utl_file.fopen ('TEST_DIR', 'mytst.txt', 'r');
  -Opens a file for writing
  outfile: = utl_file.fopen ('TEST_DIR', "Out.txt", "w");
  
  -Check the file is open
  IF utl_file.is_open (infile)
  THEN
  -lines in the file in loop
  LOOP
  BEGIN
  UTL_FILE.get_line (infile, buffer);
  APPLICATION STARTING POINT-
  Buffer IF LIKE 'foo %' THEN
  b_paragraph_started: = TRUE;
  END IF;
  -SEARCH FOR GRADS APPS
  IF b_paragraph_started AND buffering LIKE '% 4% ' THEN
  UTL_FILE.put_line (outfile, buffer, FALSE);
  END IF;
  -REQUEST FOR ENDPOINT
  Buffer IF LIKE '% ZEN' THEN
  b_paragraph_started: = FALSE;
  END IF;
  UTL_FILE.fflush (outfile);
  
  EXCEPTION
  WHEN no_data_found THEN
  EXIT;
  END;
  END LOOP;
  END IF;
  UTL_FILE.fclose (INFILE);
  UTL_FILE.fclose (outfile);
  EXCEPTION
  WHILE OTHERS THEN
  raise_application_error ("-20099, ' UTL_FILE unknown error");
  END my_app2;
  /
  
  When I run this code I get only one line: DE4.2 it ME LACK THE WHOLE PARAGRAPH
  
  PLEASE ADVISE...

  I agree with reservations of Justin on the length of a "paragraph" and the number of users that are running at the same time, so here is a version without the collections.

  CREATE or replace PROCEDURE my_app2 IS
     infile utl_file.file_type;
     outfile utl_file.file_type;
     buffer VARCHAR2(30000);
     b_paragraph_started BOOLEAN := FALSE; -- flag to indicate that required paragraph is started
     b_toprint BOOLEAN := FALSE;
     l_para_start pls_integer;  -- start of "paragraph"
  BEGIN
     infile := utl_file.fopen('TEST_DIR', 'mytst.txt', 'r');
     outfile := utl_file.fopen('TEST_DIR', 'out.txt', 'w');
     LOOP
        BEGIN
           utl_file.get_line(infile, buffer);
           IF buffer LIKE 'FOO%' THEN
              b_paragraph_started := TRUE;
              l_para_start := UTL_FILE.FGETPOS(infile) - (length(buffer) + 1);
           END IF;
           IF b_paragraph_started and buffer like '%DE4%' THEN
              b_toprint := TRUE;
           END IF;
           If buffer like 'ZEN%' THEN
              IF b_toprint THEN
                 UTL_FILE.FSEEK(infile, l_para_start);
                 utl_file.get_line(infile, buffer);
                 while buffer not like 'ZEN%' loop
                    utl_file.put_line(outfile,buffer, FALSE);
                    utl_file.get_line(infile, buffer);

  You may need to change the length (buffer) + 1 depending on your platform and if you want a blank line s NLE out paragraphs, add another call to put_line after that outside of the loop in the fi l_toprint block.

• Write data to text file generates the error

  Hi all

  I need to write data to a file using TestStand and I configired the entrance and outside like below, but I get the error message like ' an error occurred 'Write' calling in 'ITextStream' of 'Microsoft Scripting Runtime' [error Code:-2146828234].

  I followed the same procedure for reading text that works very well for me.

  Hope others might have faced the problem / or I do something wrong.

  Do what is necessary.

  

  Found problem while opening a file I used IO Mode ForReading instead of ForWriting.

  Unnecessarily the thread created, but then hope this can help someone later when they deal with a particular issue.

• Read a utf-8 text file

  Hi, until now, I used the default encoding for reading and writing text files, but I discovered it causes question marks trying to read or write the non-English characters, so I'm trying to change my code to use:

  inputstramreader and OutputStreamWriter inputreader and outputwriter, I have used before.

  However, I discovered the onlyworks linereader with InputStreamand not with inputstreamreader.

  also bufferedread is not available in api.

  It looks something like this:

  View linereader takes inputstream and not inputstreamreader.

            fc = (FileConnection) Connector.open(targetFolder + "file.txt", Connector.READ_WRITE);
              InputStream is = fc.openInputStream();
              InputStreamReader reader = new InputStreamReader(is, "UTF-8");
              String line = null;
              LineReader lineReader = new LineReader(is);
              try
              {
                  lineReader.readLine();  // skip header line
                  line = new String(lineReader.readLine());   // get line from file
              }
  

  so the question is, I have to manually write a function to read a line in the file? or is it an another workaround?

  You need to specify the encoding of the byte array and do not rely on the default encoding when you create a string to a byte array.

  Use this:

  line = new String(lineReader.readLine(), "UTF-8"));

  Thank you
  Lony

  Hi Lony,

  You may not use the operating system directory here.

  You must create the directory object in oracle.

   
  
  create or replace directory temp_dir as 'C:\temp'; 
  
  grant read , write on directory temp_dir to hr; -- Username 
  

  To create any directory, 'create any directory of grant' privilege.

   
  
  declare
      f utl_file.file_type;
      s varchar2(200) := 'Line 1';
  begin
      f := utl_file.fopen('TEMP_DIR','NCW_ET15.log','W');
      utl_file.put_line(f,s);
      utl_file.fclose(f);

  Hello I am struggling with this problem for 2 months... They get help from different I thought I solved the problem, but of no use yet I stand on zero

  Hi Ali Afzal,.

  I think that the attached example can work for you. If not, then try the solution with sending the data to a parallel running the loop and store it there.
