Using UTL_FILE i'm able to read csv file. I'm stuck up in appending some more columns to same csvYou'll struggle to append data to an existing CSV.
You'd be better to read the data from one CSV, and create another CSV using that data, and the extra data you want, and then when finished, delete the original file and rename the new file to the old filename.
You should be able to do that using External Tables to read the source file (easier than using UTL_FILE) and UTL_FILE to write the new file.

Read and write a .CSV file contains cirillic characters issue

Hi guys,
I am a developer of a web application project which uses Oracle Fusion Middleware technologies. We use JDeveloper 11.1.1.4.0 as development IDE.
I have a requirement to get a .csv file from WLS to application running machine. I used a downloadActinLinsener in front end .jspx in order to do that.
I use OpenCSV library to read and write .csv files.
Here is my code for read and write the .csv file,
public void dwdFile(FacesContext facesContext, OutputStream out) {
System.out.println("started");
String [] nextLine;
try {
FileInputStream fstream1 = new FileInputStream("Downloads/filetoberead.CSV");
DataInputStream in = new DataInputStream(fstream1);
BufferedReader br = new BufferedReader(new InputStreamReader(in,"UTF-8"));
CSVReader reader = new CSVReader(br,'\n');
//CSVReader reader = new CSVReader(new FileReader("Downloads/ACTIVITY_LOG_22-JAN-13.csv"),'\n');
List<String> list=new ArrayList();
while ((nextLine = reader.readNext()) != null) {
if(nextLine !=null){
for(String s:nextLine){
list.add(s);
System.out.println("list size ; "+list.size());
OutputStreamWriter w = new OutputStreamWriter(out, "UTF-8");
CSVWriter writer = new CSVWriter(w, ',','\u0000');
for(int i=0;i<list.size();i++){
System.out.println("list items"+list.get(i));
String[] entries = list.get(i).split(",");
writer.writeNext(entries);
//System.out.println("list items : "+list.get(i));
writer.close();
} catch (IOException e) {
e.printStackTrace();
say the filetoberead.CSV contains following data,
0,22012013,E,E,ASG,,O-0000,O,0000,100
1,111211,LI,0,TABO,B,M002500003593,,,К /БЭ60072715/,КАРТЕНБАЙ

It reads and writes the numbers and english characters correct. All cirillic characters it prints "?" as follows,
0,22012013,E,E,ASG,,O-0000,O,0000,100
1,111211,LI,0,TABO,B,M002500003593,,,? /??60072715/,?????????

can somone please help me to resolve this problem?
Regards !

Are you sure that the input file (e.g. "Downloads/filetoberead.CSV") is in UTF-8 character set? You can also check it using some text editor having a view in hex mode. If each Cyrillic character in your input file occupies a single byte (instead of two), then the file is not in UTF-8. Most probably it is in Cyrillic for Windows (CP1251).
If this is the case, you should modify the line
BufferedReader br = new BufferedReader(new InputStreamReader(in,"UTF-8"));toBufferedReader br = new BufferedReader(new InputStreamReader(in,"windows-1251"));Dimitar

How to get sql query data and write into csv file?

I am writing to seek help, in how can I create bat. script which can execute the following logic:
connection to the database
run sql query
create CSV file
output query data, into CSV file
save the CSV file
osql
-S 84.18.111.111
-U adw
-P rem
-i "c:\query.sql"
send ""
sed -e 's/,\s\+/,/g' MCI_04Dec2014.csv > localNoSpaces.csv
-o "c:\MCI_04Dec2014.csv"
This what i have so far, and I am little struggling with the logic after creating CSV file. I am unable to get the above script to work, please advice further, where I may be going wrong.
Can you create if statement logic within window's script, to check for null parameters or data feeds?
Any hints would be most appreciated.

Thank you for your reply.
Apology for posting the code irrelevant to the forum, as I am still novice scripting user.
My goal is to create window's script which can compute the above logic and send the final output file (csv), to FTP folder.
Can this logic be implemented via bat. script, if so, is there a example or tutorial i could follow, in order to achieve my task.
Any help would be much appreciated.

Labview to read and white into .csv file only

I have a security question.
Is it possible for labview to read/write into a .CSV file only and make it not applicable to the user?
for instant, labview writes to file OUTPUT.CSV,
my current system, on windows xp, i can go to output.csv and use notepad/excel to read/write and save output.csv data.
i want to make it not accessible to write or modify output.csv (ONLY POSSIBLE IF DONE USING LABVIEW PROGRAM).
how would i do something like that?
thanks in advance.
Best regards,
Krispiekream

I am not sure if you can do that. What makes this file so important? What does it do?
Depending on the reason you want to do this there might be a different/better soloution. Maybe save the file as binary and if it was opened it would not be easy to read. Or save the file in a location that has nothing to do with LabVIEW?
Under File I/O >> Advanced, There is a VI called Access Rights that you might be able to use.

If you want to copy files as fast as possible, without processing them (as the DOS "copy" or the Unix "cp" command), you can try the java.nio.channels package.
import java.nio.*;
import java.nio.channels.*;
import java.io.*;
import java.util.*;
import java.text.*;
class Kopy {
     * @param args [0] = source filename
     *        args [1] = destination filename
    public static void main(String[] args) throws Exception {
        if (args.length != 2) {
            System.err.println ("Syntax: java -cp . Kopy source destination");
            System.exit(1);
        File in = new File(args[0]);
        long fileLength = in.length();
        long t = System.currentTimeMillis();
        FileInputStream fis = new FileInputStream (in);
        FileOutputStream fos = new FileOutputStream (args[1]);
        FileChannel fci = fis.getChannel();
        FileChannel fco = fos.getChannel();
        fco.transferFrom(fci, 0, fileLength);
        fis.close();
        fos.close();
        t = System.currentTimeMillis() - t;
        NumberFormat nf = new DecimalFormat("#,##0.00");
        System.out.print (nf.format(fileLength/1024.0) + "kB copied");
        if (t > 0) {
            System.out.println (" in " + t + "ms: " + nf.format(fileLength / 1.024 / t) + " kB/s");

Export batch data into CSV file using SQL SP

Hi,
I have created WCF-Custom receive adapter to poll Sql SP (WITH xmlnamespaces(DEFAULT 'Namespace' and For XML PATH(''), Type) . Get the result properly in batch while polling and but getting error while converting into CSV by using map.
Please can anyone give me some idea to export SQL data into CSV file using SP.

How are you doing this.
You would have got XML representation for the XML batch received from SQL
You should have a flat-file schema representing the CSV file which you want to send.
Map the received XML representation of data from SQL to flat-file schema
have custom pipeline with flat-file assembler on the assembler stage of the send pipeline.
In the send port use the map which convert received XML from SQL to flat file schema and use the above custom flat-file disassembler send port

How can I read, millions of records and write as *.csv file

I have to return some set of columns values(based on current date) from the database (could be million of record also) The dbms_output can accomodate only 20000 records. (I am retrieving thru a procedure using cursor).
I should write these values to a file with extn .csv (comma separated file) I thought of using a utl_file. But I heard there is some restriction on the number of records even in utl_file.
If so, what is the restriction. Is there any other way I can achive it? (BLOB or CLOB ??).
Please help me in solving this problem.
I have to write to .csv file, the values from the cursor I have concatinated with "," and now its returning the value to the screen (using dbms_output, temporarily) I have to redirect the output to .csv
and the .csv should be in some physical directory and I have to upload(ftp) the file from the directory to the website.
Please help me out.

Jimmy,
Make sure that utl_file is properly installed, make sure that the utl_file_dir parameter is set in the init.ora file and that the database has been re-started so that it will take effect, make sure that you have sufficient privileges granted directly, not through roles, including privileges to the file and directory that you are trying to write to, add the exception block below to your procedure to narrow down the source of the exception, then test again. If you still get an error, please post a cut and paste of the exact code that you run and any messages that you received.

How do I read and write to text files on a remote computer's hard drive

I would like to read and write data to a text file on a remote computer. This is easily accomplished using one of the file functions such as "write characters to file.vi". If I am already connected to the remote computer, all I need to do is specify the path to the particular file and it will work fine.
My problem is that I want to connect to the remote computer programatically within LabVIEW (I do not want to have to use the computer's OS to establish the connection. Is there a function that I can use to do this?

Yariv,
You should really start a new thread with a new question like this, so that more people see it. Some people look primarily at threads that have no responses yet. Also, don't post the exact same question in multiple places. Or, if you must cross-post to some other forum, make sure to mention it in your question text.
I'm happy to be a brick in your Western Wall, but I'm not sure what the main objective is here. Is the main problem really getting access to the "X bytes received in Y seconds at Z bytes/sec" string? Or is it accomplishing the file transfer? And what OS and LabVIEW version are you running?
I think your problem is that you the LabVIEW System Exec command does not allow for the degree of interactivity that you need if you want to issue a sequence of commands to a command-line executable. However, under Windows XP (and, presumably, other Windows versions, though I can't check), you can tell the FTP executable to use commands from a textfile script by using the -s switch, and you can override the prompts during multiple file transfers with the -i switch:
ftp -i -s:FILEPATH SERVERNAME
If you issue a command in this format to System Exec, and make sure to create a file at FILEPATH with your command sequence (one per line), then you should at least accomplish the FTP actions. This won't give you the transfer details in the standard output, unfortunately. However, if you just want a general sense of how much was transferred and how quickly it happened, you can code that in LabVIEW by getting the resulting file sizes and using Tick Count before and after the System Exec call to see how long the transfer took.
Hope that helps,
John

Read and write existing xml file trouble !

Hi everyone !
i'm trying to save hight score of user in my game by using a xml file , in my xml file has element <best_score>0<best_score/>
and my code to do it is :
XElement best=XElement.Load("Assets/best.xml");
IEnumerable<XElement> loc = best.Elements("best_score");
foreach (XElement elem in loc)
int check=Convert.ToInt32(elem.Value.ToString());
int score_user = Convert.ToInt32(scores.ToString());
if (score_user >= check)
hight_score.Text = score.ToString();
elem.Value = scores.ToString();
// what code to save this xml file after modify ?????
else
list_box.Text = check.ToString();
i down know what method can help me save my xml file after update hight score of user in this case .
Anyone has an idea to solve it for me ? please , thanks you !
sorry about my english !

Hi,
It is not recommended to update a file withing the project, so you need to store it in the IsolatedStorage.
Here is a sample to read and write file in IsolatedStorage,
XDocument xDoc;
var file = Util.ReadFile("XMLFile.xml");
if (file != null)
xDoc = XDocument.Parse(file);
var bestScore = xDoc.Element("best_score").Value;
//do calculation
xDoc.Element("best_score").Value = "200";
Util.SaveFile("XMLFile.xml", xDoc.ToString());
For the above code to work, you need to have a file named "XMLFile.xml" in your IsolatedStorage, with data as "<best_scrore>200</best_scrore>"
To read and write file:
public static class Util
public static void SaveFile(string filename, string data)
try
using (var store = System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication())
using (var stream = new IsolatedStorageFileStream(filename, FileMode.Create, FileAccess.ReadWrite, store))
StreamWriter writer = new StreamWriter(stream);
writer.Write(data);
writer.Close();
catch (Exception)
Debug.WriteLine("Couldn't save the file.");
public static string ReadFile(string filename)
try
String data;
if (!IsolatedStorageFile.GetUserStoreForApplication().FileExists(filename)) return null;
using (var store = System.IO.IsolatedStorage.IsolatedStorageFile.GetUserStoreForApplication())
using (var stream = new IsolatedStorageFileStream(filename, FileMode.Open, FileAccess.ReadWrite, store))
StreamReader stmReader = new StreamReader(stream);
data = stmReader.ReadToEnd();
stmReader.Close();
return data;
catch (Exception)
return null;

How we write into properties file using get class method

Hi
I want to set some value into properties file using given code
can any one please tell me how i can do this.
property file
setting.properties
Name     =     abc
and code I use is
java.io.InputStream oInputStream = this.getClass().getResourceAsStream("Setting.properties");
               Properties obj = new Properties();
               obj.load(oInputStream);

               System.out.println("myName :"+myName);
               obj.setProperty("Name","def");
               FileOutputStream oOutput= new FileOutputStream("Setting.properties");
               obj.store(oOutput, "");
thanks.

You can't.
If you have properties that change dynamically, you should not be using a properties file that sits in the classpath, you should be using Preferences, or a properties file that sits in some application or possibly even user directory, but not one in the classpath. The proper way to do this, would be to have a properties file in your jar (or otherwise in your classpath) that contains the defaults, and another one outside of the classpath in one of the twwo above mentioned areas, then, you read the default one only if the other doesn't exist, or you read the default one first, then read the other overwriting the values from the defaults.
Don't forget to save the properties again (right after loading if you loaded, or always load, the defaults) after every change.

Exporting query result set into CSV file using Forms

Hi ,
My requirement is
-> I need to create a form where I have a Multi line text box and two button.
-> When I enter a query in text box and click on Execute button, It should execute a select query.
-> After execution, Result set needs to be exported into an Excel file.
Please give a hint how to do this????
Thanks,
maddy

as you are using text item to write SQL query by the user
so for that you need to use the exec_sql package to parse the text items query and get definitions and values of the columns being
resulted in the result set of the query.
once your query is execute to the desired connection then you need to use fetch the result to the CSV file by use of the TEXT_io package
which will open the text file with .csv extension and you have to pass the each line to that text file with comma separated values as "ss","rr" etc.
or you can use the ole2 package to call the excel application and then fetch the data of exe_sql query to that.

Reading and Writing large Excel file using JExcel API

hi,
I am using JExcelAPI for reading and writing excel file. My problem is when I read file with 10000 records and 95 columns (file size about 14MB), I got out of memory error and application is crashed. Can anyone tell me is there any way that I can read large file using JExcelAPI throug streams or in any other way. Jakarta POI is also showing this behaviour.
Thanks and advance

Sorry when out of memory error is occurred no stack trace is printed as application is crashed. But I will quote some lines taken from JProfiler where this problem is occurred:
          reader = new FileInputStream(new File(filePath));
          workbook = Workbook.getWorkbook(reader);
          *sheeet = workbook.getSheet(0);* // here out of memory error is occured
           JProfiler tree:
jxl.Workbook.getWorkBook
      jxl.read.biff.File
             jxl.read.biff.CompoundFile.getStream
                   jxl.read.biff.CompoundFile.getBigBlockStream Thanks
