Read a CSV file into Flex

Hi all,
I'm new to flex and have been asked to provide a small widget
that will display the contents of a csv in a list. Can I use the
HTTPService to open a csv file and then create an actionscript 3
function to parse it? If so can anyone point me to a tutorial on
how to parse a csv file please.
Thanks in advance

Hello Sir,
I am new to flex and want to read a csv file and using below code but does not seems to be working. Can you please help?
i use below code but did not work
var file:File = evt.currentTarget as File;
         file = file.resolvePath(file.nativePath);
         var fileStream:FileStream = new FileStream();
         fileStream.open(file, FileMode.READ);
         var fileData:String = fileStream.readUTFBytes(fileStream.bytesAvailable);
         var endings:Array = [File.lineEnding, "\n", "\r"];
but for some reason it return "ÐÏ ࡱá" funny value. Any idea why don't i get the correct data from file.
belwo is the csv file i am trying to open.

How to read/write .CSV file into CLOB column in a table of Oracle 10g

I have a requirement which is nothing but a table has two column
create table emp_data (empid number, report clob)
Here REPORT column is CLOB data type which used to load the data from the .csv file.
The requirement here is
1) How to load data from .CSV file into CLOB column along with empid using DBMS_lob utility
2) How to read report columns which should return all the columns present in the .CSV file (dynamically because every csv file may have different number of columns) along with the primariy key empid).
eg: empid report_field1 report_field2
1 x y
Any help would be appreciated.

If I understand you right, you want each row in your table to contain an emp_id and the complete text of a multi-record .csv file.
It's not clear how you relate emp_id to the appropriate file to be read. Is the emp_id stored in the csv file?
To read the file, you can use functions from [UTL_FILE|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_file.htm#BABGGEDF] (as long as the file is in a directory accessible to the Oracle server):
declare
    lt_report_clob CLOB;
    l_max_line_length integer := 1024;   -- set as high as the longest line in your file
    l_infile UTL_FILE.file_type;
    l_buffer varchar2(1024);
    l_emp_id report_table.emp_id%type := 123; -- not clear where emp_id comes from
    l_filename varchar2(200) := 'my_file_name.csv';   -- get this from somewhere
begin
   -- open the file; we assume an Oracle directory has already been created
    l_infile := utl_file.fopen('CSV_DIRECTORY', l_filename, 'r', l_max_line_length);
    -- initialise the empty clob
    dbms_lob.createtemporary(lt_report_clob, TRUE, DBMS_LOB.session);
    loop
      begin
         utl_file.get_line(l_infile, l_buffer);
         dbms_lob.append(lt_report_clob, l_buffer);
      exception
         when no_data_found then
             exit;
      end;
    end loop;
    insert into report_table (emp_id, report)
    values (l_emp_id, lt_report_clob);
    -- free the temporary lob
    dbms_lob.freetemporary(lt_report_clob);
   -- close the file
   UTL_FILE.fclose(l_infile);
end;This simple line-by-line approach is easy to understand, and gives you an opportunity (if you want) to take each line in the file and transform it (for example, you could transform it into a nested table, or into XML). However it can be rather slow if there are many records in the csv file - the lob_append operation is not particularly efficient. I was able to improve the efficiency by caching the lines in a VARCHAR2 up to a maximum cache size, and only then appending to the LOB - see [three posts on my blog|http://preferisco.blogspot.com/search/label/lob].
There is at least one other possibility:
- you could use [DBMS_LOB.loadclobfromfile|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#i998978]. I've not tried this before myself, but I think the procedure is described [here in the 9i docs|http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96591/adl12bfl.htm#879711]. This is likely to be faster than UTL_FILE (because it is all happening in the underlying DBMS_LOB package, possibly in a native way).
That's all for now. I haven't yet answered your question on how to report data back out of the CLOB. I would like to know how you associate employees with files; what happens if there is > 1 file per employee, etc.
HTH
Regards Nigel
Edited by: nthomas on Mar 2, 2009 11:22 AM - don't forget to fclose the file...

How to read the CSV Files into Database Table

Hi
Friends i have a Table called tblstudent this has the following fields Student ID, StudentName ,Class,Father_Name, Mother_Name.
Now i have a CSV File with 1500 records with all These Fields. Now in my Program there is a need for me to read all these Records into this Table tblstudent.
Note: I have got already 2000 records in the Table tblstudent now i would like to read all these CSV File records into the Table tblstudent.
Please give me some examples to do this
Thank your for your service
Cheers
Jofin

1) Read the CSV file line by line using BufferedReader.
2) Convert each line (record) to a List and add it to a parent List. If you know the columns before, you might use a List of DTO's.
3) Finally save the two-dimensional List or the List of DTO's into the datatable using plain JDBC or any kind of ORM (Hibernate and so on).
This article contains some useful code snippets to parse a CSV: http://balusc.xs4all.nl/srv/dev-jep-csv.html

Best way to read a CSV file into an internal table

Hi,
I have a comma seprated file, which I need to read into an internal table, and be able to look at particular values - basically looping round and populating BDC fields. Whats the easiest way of doing this?

The easiest way would be to define a flat interal table.
Data: begin of itab occurs 0,
      rec(1000) type c,
      end of itab.
Then call the function module GUI_UPLOAD to get the data into your internal table from the file on the frontend. I assume that you know how to use this function module. You could also use the method GUI_UPLOAD of the class CL_GUI_FRONTEND_SERVICES.
For example, say you have a comman delimited file with materail number, plant, quantity in it.
4000001,0004,1.00
4000002,0006,2.00
Define another internal table to hold the data.
Data: begin of itab2 occurs 0,
      matnr type mara-matnr
      werks type marc-werks
      quant(10) type c.
      end of itab2.
Then loop at the internal table(ITAB) and use the split statement to split it up into the appropriate fields of the other interal table(ITAB2).
Loop at itab.
clear itab2.
split itab-rec at ',' into itab2-matnr
                           itab2-werks
                           itab2-quant.
append itab2.
endloop.
That's it.

Read CSV file into a 1-D array

Hi
I would like to read a csv file into a cluster of 4 elements which would then be read into a 1-D array.
My cluster contains a typedef, a double, a boolean, and another typedef.
Basically it could be seen as:
Bob Runs, 4, T, Bob
Mary sits, 5, F, Mary
Bob Sits, 2, F, Bob
Mary Runs, 9, T, Mary
(keeps growing)
Are there any good examples for what I am trying to put together that I could leverage, or is it better to use a different input file than a csv. I am trying to make my program more flexable and easier to make adjustments even after the executable is created. My line items seem to be growing exponentially and is getting difficult to manage in the LV window.
Thanks
Solved!
Go to Solution.

Unless your CSV file is huge, I'd use "Read from Spreadsheet File" with the delimiter set as "," and the type as string. This will give you a 2D array of strings. You could then separate out each column of the array, convert to the appropriate data type, and use Index & Bundle Cluster Array to build your array of clusters. Something like this (except I'm using a string constant in place of reading from the file).

Question about reading csv file into internal table

Some one (thanks those nice guys!) in this forum have suggested me to use FM KCD_CSV_FILE_TO_INTERN_CONVERT to read csv file into internal table. However, it can be used to read a local file only.
I would like to ask how can I read a CSV file into internal table from files in application server?
I can't simply use SPLIT as there may be comma in the content. e.g.
"abc","aaa,ab",10,"bbc"
My expected output:
abc
aaa,ab
10
bbb
Thanks again for your help.

Help reading .csv file into an arraylist

i need to read a csv file into an arraylist and then print the arraylist to the screen.

ok, so do i need to write a file carsclass.java or is the line:
ArrayList<CarsClass> carsClass = new ArrayList<CarsClass>(" write all fields");
going to define my carsclass objects? how do i write my fields for each of the 7 categories?
i believe i can easily add to and print the arraylist, but i'm confused how to go about creating this arraylist in the first place. do i just create carclass.java and save them all as strings? i guess my question is mainly how should i structure this? any suggestions/help is appreciated.

String.split uses regular expressions.Ahh yeah ummm (slaps forehead) I'd forgotten that... so maybe StringTokeniser is more accessible for noob's. Sorry.
Anyway... if all you want/need to so is store a bunch of String field values then how about using an array of String's instead of individual fields... maybe something like:
forums\Car.java
* Car Data Transfer Object. All fields are final, making objects of this class
* thread safe(r).
* @author keith
package forums;
import krc.utilz.stringz.Arrayz;
public class Car
// class attributes                       // variables //isn't actually wrong, it's just not quit right.
private final String[] fields;            // final means values are write once, read many times, which is thread safe(r).
   * Initialises the new Cars fields to the given fields array.
   * @param fields - an array of any (reasonable) length
public Car(String[] fields) {             // no need to comment a constructor as a constructor.
    this.fields = fields;                   // much better to provide javadoc comments explaining
}                                         // what the method does and how to use it.
   * Returns this Car's fields as one long string.
public String toString() {                // It's actually GOOD to be a lazy programmer.
    return Arrayz.join(", ", this.fields); // I have reused my Arrayz.join in several projects.
                                            // I think you can use Array.toString (new in 1.6) instead.
krc\utilz\stringz\Arrayz.java
package krc.utilz.stringz;
import java.util.List;
import java.util.ArrayList;
public class Arrayz
    * returns true if the given value is in the args list, else false.

    return false;
    * append the elements of array into one string, seperated by FS
    * @param a - an array of strings to join together

    * --> Bob The Builder
    * System.out.println("String[] array = {\""+join(array, "\",\"")+"\"};");
    * --> String[] array = {"Bob","The","Builder"};
public static String join(String FS, String[]... arrays) {
    StringBuffer sb = new StringBuffer();
    for (String[] array : arrays)
      sb.append(join(array, FS));
    return(sb.toString());
public static String join(String[] array) {
    return(join(array, " "));
public static String join(String[] a, String FS) {
    if (a==null) return null;
    if (a.length==0) return "";
    StringBuffer sb = new StringBuffer(a[0]);
    for (int i=1; i<a.length; i++) {
      sb.append(FS+a);
return sb.toString();
* append all the elements of the given arrays into one big array
* @param String[]... arrays - to be concatenated
* @return String[] - one big array
public static String[] concatenate(String[]... arrays) {
List<String> list = new ArrayList<String>();
for(String[] array : arrays) {
for(String item : array) {
list.add(item);
return(list.toArray(new String[0]));
I guess that Arrayz class might be a bit beyond you at the moment so don't worry too much if you can't understand the code... there are no nasty surprises in it... just cut and paste the code, change the package name, and use it (for now).

2 - I need to create a dynamic table. The same type of the one I choose at parameter screen.
3 - Then I need to read the csv and put the data into this dynamic table.
4 - Later I need to insert the data from the dynamic table into the standard table (the one on the parameter screen).
How do I do this job? Do you have an example? Thanks.

Read a CSV file and dynamically generate the insert

I have a requirement where there are multiple csv's which needs to be exported to a sql table. So far, I am able to read the csv file and generate the insert statement dynamically for selected columns however, the insert statement when passed as a parameter
to the $cmd.CommandText
does not evaluate the values
How to evaluate the string in powershell
Import-Csv -Path $FileName.FullName | % {
# Insert statement.
$insert = "INSERT INTO $Tablename ($ReqColumns) Values ('"
$valCols='';
$DataCols='';
$lists = $ReqColumns.split(",");
foreach($l in $lists)
$valCols= $valCols + '$($_.'+$l+')'','''
#Generate the values statement
$DataCols=($DataCols+$valCols+')').replace(",')","");
$insertStr =@("INSERT INTO $Tablename ($ReqColumns) Values ('$($DataCols))")
#The above statement generate the following insert statement
#INSERT INTO TMP_APPLE_EXPORT (PRODUCT_ID,QTY_SOLD,QTY_AVAILABLE) Values (' $($_.PRODUCT_ID)','$($_.QTY_SOLD)','$($_.QTY_AVAILABLE)' )
$cmd.CommandText = $insertStr #does not evaluate the values

Read from .csv file at startup

Hi, I am making my first app and I need to read data from a csv file into a list. I first created this functionality on a console application, but now when I try to use the same code it does not work.
class FoodDataBase {
private List<Food> foodDataBase = new List<Food>();
private string locationOfCSVFile = "C:\\Egen Programmering\\LivsmedelsDatabas\\LivsmedelsDatabas\\LivsmedelsDatabas.csv";
public FoodDataBase() {
PopulateFoodDataBase();
private bool PopulateFoodDataBase() {
// connect reader to the CSV file
var reader = new StreamReader(File.OpenRead(@locationOfCSVFile));
if (reader == null) {
return false;
But I get an error message saying "The name 'File' does not exist in the current context". I have googled around a bit but can´t find an easy way to do it. Is there not any good way of doing this in WinRT? Should I convert my csv file to something
else?

Hi PontusL,
As I can see from your code, you are trying to read a file from a forbidden place, see this for more information:

Reading a CSV file from server

Hi All,
I am reading a CSV file from server and my internal table has only one field with lenght 200. In the input CSV file there are more than one column and while splitting the file my internal table should have same number of rows as columns of the input record.
But when i do that the last field in the internal table is appened with #.
Can somebody tell me the solution for this.
U can see the my code below.
data: begin of itab_infile occurs 0,
         input(3000),
      end of itab_infile.
data: begin of itab_rec occurs 0,
         record(200),
      end of itab_rec.
data: c_comma(1) value ',',
        open dataset f_name1 for input in text mode encoding default.
        if sy-subrc <> 0.
          write: /, 'FILE NOT FOUND'.
          exit.
        endif.
do
read dataset p_ipath into waf_infile.
split itab_infile-input at c_sep into table itab_rec.
enddo.
Thanks in advance.
Sunil

Sunil,
You go not mention the platform on which the CSV file was created and the platform on which it is read.
A common problem with CSV files created on MS/Windows platforms and read on unix is the end-of-record (EOR) characters.
MS/Windows usings <CR><LF> as the EOR
Unix using either <CR> or <LF>
If on unix open the file using vi in a telnet session to confirm the EOR type.
The fix options.
1) Before opening the opening the file in your ABAP program run the unix command dos2unix.
2) Transfer the file from the MS/Windows platform to unix using FTP using ascii not bin. This does the dos2unix conversion on the fly.
3) Install SAMBA and share the load directory to the windows platforms. SAMBA also handles the dos2unix and unix2dos conversions on the fly.
Hope this helps

Data formatting and reading a CSV file without using Sqlloader

I am reading a csv file to an Oracle table called sps_dataload. The table is structured based on the record type of the data at the beginning of
each record in the csv file. But the first two lines of the file are not going to be loaded to the table due to the format.
Question # 1:
How can I skip reading the first two lines from my csv file?
Question # 2:
There are more fields in the csv file than there are number of columns in my table. I know I can add filler as an option, but then there are
about 150 odd fields which are comma-separated in the file and my table has 8 columns to load from the file. So, do I really have to use filler
for 140 times in my script or, there is a better way to do this?
Question # 3:
This is more of an extension of my question above. The csv file has fields with block quotes - I know this could be achieved in sql loader when we mention Occassionally enclosed by '"'.
But can this be doable in the insert as created in the below code?
I am trying to find the "wrap code" button in my post, but do not see it.
Heres my file layout -

Justin, thanks. I did happen to change my pl sql procedure using utl_file.get_file and modifying the instr function based on position of ',' in the file, but my procedure is getting really big and too complex to debug. So I got motivated to use external tables or sql loader as plan b.
As I was reading more about creating an external table as an efficient way and thus believe I can perhaps build an extern table with my varying selection from the file. But I am still unclear if I can construct my external table by choosing different fields in a record based on a record identifier string value (which is the first field of any record). I guess I can, but I am looking for the construct as to how am I going to use the instr function for selecting the field from the file while creating the table.

How to import old iPhone SMS.CSV file into new iPhone?

Hey everyone,
So I've spent a couple days on this as I just upgraded to the iPhone5S from my 4S. Long story short, my backup restore didn't work after multiple tries (gave me the file is corrupt or not compatible with the iPhone error).
I tried:
-reinstalling itunes
-updating itunes
-combining the 5S backup with the old 4S backup
-tinyumbrella
and a few of other things as I've forgot now.
The most important things I needed was the contact list and SMS history. I've got the contact list from extracting is successfully from the iTunes backup folder and using iCloud, but cannot figure out how to import the SMS.CSV file into my iPhone5S.
Any suggestions on how I can get my SMS messages from my iPhone4s into my 5S?
If anyone has any other suggestions on getting my Backup Restore to work that would be awesome too!
Thanks!

A word on SMS text messages. It is pracitcally impossible to import an SMS text-messages file to a new iPhone and have the Messages app on the new device read the messages.
You can transfer, however contacts and other individual data (such as calendars and notes) from one iphone to the next. I had my old Nokia which whose contacts I exported to a CSV file. I then imported the file to my iphone which converted the file into multiple contacts in the Contacts app on the iphone. You can use a contact management app such as this one in order to import the contact file to the new iPhone.

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?
