Read data from a CSV file

hi,
i've managed to make a CSV file which includes logged data of how much my NXT car is turning left(L),right(R) or going straight(S). format is:direction/timer value (L/1922 means it went to left for 1922 ms).
where i got stuck is how can i read those time and direction values from csv file in such way that those values could be used for the motor move input?
Actually what i'm trying to do is severeal VIs which function like record/play action in NXT Toolkit.
(i've attached the vi and the csv file, the file extension is CSV but it is not written in csv format it's a basic txt file actually )

after i get the data in 1-D array format I cannot convert it to string so that i can send it by write BT message. i tried flatten to string but didnt work out
[nevermind the mess, just see the part where the 1-D string is being converted to string]

Read data from a .csv located on another server

Hi!:
I've an application that currently reads some data from a .CSV file that I upload everyday using a file browser item plus a custom procedure to parse it. I was wondering if it'd be possible to automatically read the information from a remote file located in a web server. I've been looking for ways to do this, but couldn't find anything. Do you have any ideas?.
thanks for your help!

I'm pretty sure the answer is no, if it's not on the database server.
However (this isn't my area of expertise really) if your server admins have the ability to somehow mount a network drive (or volume? sorry i don't know the terminology or details) to the database server and then, as far as the database server is concerned, the file looks/walks/talks as if it's local on the same box and then you can reference it via UTL_FILE, an external table, etc.

Import data from excel/csv file in web dynpro

Hi All,
I need to populate a WD table by first importing a excel/CSV file thru web dynpro screen and then reading thru the file.Am using FileUpload element from NW04s.
How can I read/import data from excel / csv file in web dynpro table context?
Any help is appreciated.
Thanks a lot

Hi,
Here are the basic steps needed to read data from excel spreadsheet using the Java Excel API(jExcel API).
jExcel API can read a spreadsheet from a file stored on the local file system or from some input stream, ideally the following should be the steps while reading:
Create a workbook from a file on the local file system, as illustrated in the following code fragment:
          import java.io.File;
          import java.util.Date;
          import jxl.*;
         Workbook workbook = Workbook.getWorkbook(new File("test.xls"));
On getting access to the worksheet, once can use the following code piece to access individual sheets. These are zero indexed - the first sheet being 0, the second sheet being 1, and so on. (You can also use the API to retrieve a sheet by name).
          Sheet sheet = workbook.getSheet(0);
After getting the sheet, you can retrieve the cell's contents as a string by using the convenience method getContents(). In the example code below, A1 is a text cell, B2 is numerical value and C2 is a date. The contents of these cells may be accessed as follows
Cell a1 = sheet.getCell(0,0);
Cell b2 = sheet.getCell(1,1);
Cell c2 = sheet.getCell(2,1);
String a1 = a1.getContents();
String b2 = b2.getContents();
String c2 = c2.getContents();
// perform operations on strings
However in case we need to access the cell's contents as the exact data type ie. as a numerical value or as a date, then the retrieved Cell must be cast to the correct type and the appropriate methods called. The code piece given below illustrates how JExcelApi may be used to retrieve a genuine java double and java.util.Date object from an Excel spreadsheet. For completeness the label is also cast to it's correct type. The code snippet also illustrates how to verify that cell is of the expected type - this can be useful when performing validations on the spreadsheet for presence of correct datatypes in the spreadsheet.
String a1 = null;
Double b2 = 0;
Date c2 = null;
                    Cell a1 = sheet.getCell(0,0);
                    Cell b2 = sheet.getCell(1,1);
                    Cell c2 = sheet.getCell(2,1);
                    if (a1.getType() == CellType.LABEL)
                       LabelCell lc = (LabelCell) a1;
                       stringa1 = lc.getString();
                     if (b2.getType() == CellType.NUMBER)
                       NumberCell nc = (NumberCell) b2;
                       numberb2 = nc.getValue();
                      if (c2.getType() == CellType.DATE)
                        DateCell dc = (DateCell) c2;
                        datec2 = dc.getDate();
                       // operate on dates and doubles
It is recommended to, use the close() method (as in the code piece below)   when you are done with processing all the cells.This frees up any allocated memory used when reading spreadsheets and is particularly important when reading large spreadsheets.
          // Finished - close the workbook and free up memory
          workbook.close();
The API class files are availble in the 'jxl.jar', which is available for download.

How can I import data from a csv file into databse using utl_file?

Hi,
I have two machines (os is windows and database is oracle 10g) that are not connected to each other and both are having the same database schema but data is all different.
Now on one machine, I want to take dump of all the tables into csv files. e.g. if my table name is test then the exported file is test.csv and if the table name is sample then csv file name is sample.csv and so on.
Now I want to import the data from these csv files into the tables on second machine. if I've 50 such csv files, then data should be written to 50 tables.
I am new to this. Could anyone please let me know how can I import data back into tables. i can't use sqlloader as I've to satisfy a few conditions while loading the data into tables. I am stuck and not able to proceed.
Please let me know how can I do this.
Thanks,
Shilpi

Why you want to export into .csv file.Why not export/import? What is your oracle version?

I need to import data from a CSV file to an Oracle table

I need to import data from a CSV file to an Oracle table. I'd prefer to use either SQL Developer or SQL Plus code.
As an example, my target database is HH910TS2, server is ADDb0001, my dB login is em/em, the Oracle table is AE1 and the CSV file is AECSV.
Any ideas / help ?

And just for clarity, it's good to get your head around some basic concepts...

It does not have any code of it's own (although it may have some "commands" that are SQL Developer specific)
SQL*Plus is another front end (character based rather than GUI) that submits code to the database and displays the results. It also does not have code of it's own although there are SQL*Plus commands for use only in the SQL*Plus environment.
The "code" that you are referring to is either SQL or PL/SQL, so you shouldn't limit yourself to thinking it has to be for SQL Developer or SQL*Plus. There are many front end tools that can all deal with the same SQL and/or PL/SQL code. Focus on the SQL and/or PL/SQL side of your coding and don't concern yourself with limitations of what tool you are using. We often see people on here who don't recognise these differences and then ask why their code isn't working when they've put SQL*Plus commands inside their PL/SQL code. ;)

Right-clicking "data" on the model tab can you see the data?
In your code there's written:
P$CRLOAD_FILE=Y:/1 Metadata/Account//Account.csv
Is it right the double slash before the file name?

View Object to read data from a java file

Hi,
I am using JDeveloper 11.1.1.4 and ADF-BC in my application.
For one of my view objects , I want the data to be read from a java file which exposes some method to return a collection.
I cannot use a static view object in this case.
Please suggest the best way to implement this requirement.Basically build a view object that should read data from a java file.
Thanks,
Praveen

Depending on your use case you can either use a programmatic VO or directly expose the JV class as a data control.

Read data from a text file, one line at a time.

I need to read data from a text file, and display each line in a String Indicator on Front Panel. It displays each line, but I get Error 4, End Of Line, unless I enter an extra line of data in the file that I don't need. I tried Read From Text File.vi, made by Nat Instr, and it gave the same error.

The Read from Text File.vi reads data from a text file line by line until the user stops the VI manually with the Stop button on the front panel, or until an error (such as "Error 4, End of file") occurs. If an error occurs, the Simple Error Handler.vi pops up a dialog that tells you which error occurred.
The Read from Text File.vi uses a while loop, but if you knew how many lines you wanted to read, you could replace the while loop with a for loop set to read that many lines from the file.
If you need something more dynamic because the number of lines in your files vary, then you could change the code of the Read from Text File.vi to the expect "Error 4, End of file" and handle it appropriately. This would require unbundling the error cluster that comes fro
m the Read File function with the Unbundle By Name function, so that you can expose the individual error "status" and error "code" values stored in the cluster. If the value of the error "code" is 4, then you can change the error "status" from true to false, and you can rebundle the cluster with the Bundle by Name function. Setting the error "status" to false instructs the Simple Error Handler to ignore the error. Otherwise, pass the original error cluster to the Simple Error Handler.vi, so that you can see what the error is.
Of course, if you're not interested in what the errors are, you could just remove the Simple Error Handler.vi, but then you wouldn't see any error messages.
Best of Luck,

Reading data from an excel file

Hi,
I want to read data from the excel file and display it in
jsp page. Iam getting the following error:

You might want to look at the POI project (an open source Jakarta sub-project) that allows you to create/modify/read excel files via Java code. That might be more flexible and easier than what you're currently trying to do.

GUI_UPLOAD to read data from an Excel File

What could be the reason?

Do you have it trying to read that same file on your C drive or is the file actually deployed somewhere on the server?

Read data from a sequential file to fill an arrray

I am trying to read data from a sequential file to fill an array and then use the array for calculations. I believe my program is reading the file; however when I try to use the data for calculations the results show up as boxes rather than numbers. Can someone please take a look and give me some insight into where I am going wrong. The sequential file has the following data:
5.0
5.35
5.5
5.75
Here is my code from that portion of the program. I can send the entire program if necessary.
private void calcResults(TextArea loanResults, double amount, double interest, int term ) throws IOException {
     DecimalFormat df = new DecimalFormat("$###,###.00");
     NumberFormat formats = new DecimalFormat("#0.00");
     StringBuffer buffer=new StringBuffer();
     loanResults.append("Month No.\tMonthly Payment\t\tInterest\t\tBalance\n");
     double monthlyPay = amount*Math.pow(1+interest,term)*interest/(Math.pow(1+interest,term)-1);
     monthlyPayment.setText("" + (formats.format(monthlyPay)));
     double principal= amount;
      * Loop through each month of a given loan
    int month;
     for (int i=0; i<term; i++)
try {
     int j = 0;
     BufferedReader in = new BufferedReader(new FileReader("rates.txt"));
     String temp = "";
     while((temp = in.readLine()) != null) {
        j++;
        strRate[j] = temp;
        RateValue1 = Double.parseDouble(loanAmountTxFld.getText());
        in.close();
         catch (FileNotFoundException e) {
             System.out.println("Can't find file rate.txt!");
             return;
      month= i+1;
      double rate =principal*interest;
      double balance=principal+rate-monthlyPay;
      loanResults.append((month) + "\t\t" + (formats.format(principal) + "\t\t" + (formats.format(rate) + "\t\t"
                        + (formats.format(balance)     + "\n"))));
      principal=balance;
      GraphArea.append(formats.format(balance)     + "\n");
*Method for determining which loan option was chosen
private void calc() throws IOException{
String interestTerms = (String) cOption.getSelectedItem();
if (interestTerms.equalsIgnoreCase("5 yrs at 5.00"))
     calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), 0.05/12, 60);
else if (interestTerms.equalsIgnoreCase("7 yrs at 5.35"))
    calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), RateValue1/12, 84);
else if (interestTerms.equalsIgnoreCase("15 yrs at 5.50"))
     calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), 0.0550/12, 180);
else if (interestTerms.equalsIgnoreCase("30 yrs at 5.75"))
     calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), 0.0575/12, 360);
else if (interestTerms.equalsIgnoreCase("       "))
    calcResults(loanResults, Double.parseDouble(loanAmountTxFld.getText()), Double.parseDouble(loanInterestTxFld.getText())/100/12,Integer.parseInt(loanTermTxFld.getText())*12);
}

ok, I fixed my program per your suggestion and I still cannot get it to work. I get the same result where the ouput is just a bunch of boxes. I also tried to print to see what I am getting and all I see is the values of the array [5.0,5.35,5.5,5.75] but I cannot seem to pass that to the calculations. I wish I could figure this out. Does anybody have any suggestions as to what I am doing wrong. This is the portion of my code that I am having issues with:
private void calcResults(TextArea loanResults, double amount,double interest, int term ) throws IOException {
     DecimalFormat df = new DecimalFormat("$###,###.00");
     NumberFormat formats = new DecimalFormat("#0.00");

     loanResults.append("Month No.\tMonthly Payment\t\tInterest\t\tBalance\n");
     double monthlyPay = amount*Math.pow(1+interest,term)*interest/(Math.pow(1+interest,term)-1);
     monthlyPayment.setText("" + (formats.format(monthlyPay)));
     double principal= amount;
      * Loop through each month of a given loan
    int month;
     for (int i=0; i<term; i++)
      month= i+1;
      double rate =principal*interest;
      double balance=principal+rate-monthlyPay;
      loanResults.append((month) + "\t\t" + (formats.format(principal) + "\t\t" + (formats.format(rate) + "\t\t"
                        + (formats.format(balance)     + "\n"))));
      principal=balance;
      GraphArea.append(formats.format(balance)     + "\n");
private void readFile() throws IOException
try {
     int j = 0;
     BufferedReader in = new BufferedReader(new FileReader("rates.txt"));

        strRate[j] = temp;
        j++;
RateValue1 = Double.valueOf(((String)(strRate[1]))
).doubleValue();
//        RateValue1 = Double.parseDouble(loanAmountTxFld.getText());
        in.close();

Need to read data from a text file

I need to read data from a text file and create my own hash table out of it. I'm not allowed to use the built in Java class, so how would I go implementing my own reading method and hash table class?

It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.
[http://java.sun.com/docs/books/tutorial/essential/io/]
*Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

In my case when I use my sqldeveloper I can see data successfully inserted in my target table and also in error table (data that can't satisfy the constraint) .But I was unable to check this by following the above mentioned 10 th step and got this error.
