How to read multiple lines from an external file to the Oracle data base

Hi Guys,
I have an external file which contains multiple lines and I want to read it to the data base .I have done it for the file if it contains one line.
Please guide me how to retrieve all the lines into the data base.And also tell me how Oracle will come to know the end of the line in the file
Thanks,

How to read every line from a text file???

How can i read every line from my text file ("eka.txt")
now it only reads the first line and prints it out.
What is wrong with this?
import java.io.*;
import java.util.*;
class Testi{
     public static void main(String []args)throws IOException {
     BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
File inputFile = new File ("eka.txt");
FileReader fis =new FileReader(inputFile);
BufferedReader bis = new BufferedReader(fis);
String test=bis.readLine();
String tmp= "";
while((bis.readLine().trim() != null)) {
int spacefound=0;
int l=test.indexOf(" ");
     for(int i=0;i<test.length();i++){
     char c=test.charAt(i);
     if(c!=' ') tmp+=""+c;
     if(c==' ' && (spacefound<1) && !(tmp.equals(""))){
     tmp+=""+c;
     spacefound++;
     if(tmp.length()==l) {
     System.out.println(tmp);
     tmp="";
     spacefound=0;
     if(tmp.length()<l){
     for(int i=0;i<=(l-tmp.length());i++)
     tmp+=""+' ';
     System.out.println(tmp);

Try this code, Hope it servers your purpose.

          String test=bis.readLine();
          while(test != null) {
               StringTokenizer st = new StringTokenizer(test," ");
               while(st.hasMoreTokens())
                    System.out.println(st.nextToken());

Since the word "TEXT" is formed of 4 letters, you would read the text file 4 bytes by four bytes. Wrong on two counts. First, the file may not be encoded 1 byte per character. It could be utf-16 in which case it would be two byte per character. Second, even if it were 1 byte per character, the string "Text" may not start on a 4 byte boundary.
Consider a FileInputStream object "fis" that points to your text file. use fis.read(byte[] array, int offset, int len) to read every four bytes. Convert the "TEXT" String into a byte array "TEXT".getBytes(), and yous the Arrays class to compare the equality of the read bytes with your "TEXT".getBytes()Wrong since it relies on my second point and will fail when fis.read(byte[] array, int offset, int len) does not read 4 bytes (as is no guaranteed to). Check the Javadoc. Also, the file may not be encoded with the default character encoding.
The problem is easily solved by reading a line at a time using a BufferedReader wrapping an InputStreamReader wrapping a FileInputStream and specifying the correct character encoding.

How to read last line from a .txt file?

Hello
I have a string: e.g. "my name is John"
and i wanna verify if this string is equal with the last line from a text file
for example, if in the txt file i have:
asdasd
sdgsdfgasd
asdfgadfgadf
sdgasdgsdf
my name is john
then it's OK.
but if i have
asdgsdfg
dsfhsdfhsd
sdgasdfg
sdgsdg
my name is Jdfgsdg
this is not correct
How should i do this?
Thanks:)

Read from the beginning an discard all lines (if you have a small file), or use RandomAccessFile and scan from the end till you find the beginning of the last line.

How to read multiple lines from a command prompt?

I usually read from a command prompt like this:
String answer;
System.out.println("Please enter the required data");
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
answer = reader.readLine();
reader = null;
} catch (Exception e) {
System.out.println("There was an exception trying to read " + e);
answer = "";
This has worked fine for years when all I wanted was one line answers.
Now I am trying to prompt for multiple line answers. Is there a way to read into a string array rather than just a string? What class would I use for that?
Thanks a lot!

The easiest approaches would be to read a line at a time until you've read enough lines, whether by a known fixed line count, or a token count, or by reading some sentinel toek, OR read a token at a time using Scanner.next() until you've determined you're done. Which one is more appropriate depends on your situation.

How to read partcicular line from a txt file

in a text file let there be 50 lines
while reading the line if the line is having "name" as a string in that line then i have to store the next two consecutive lines in a string as array....
Similar way and so on......
How can we do this....

You need a BufferedReader:
http://java.sun.com/j2se/1.4.2/docs/api/java/io/BufferedReader.html
for example:try {
    BufferedReader br = new BufferedReader(new FileReader("myfile.txt"));
    String line;
    while ( (line=br.readLine()) != null ) {
     if (line.indexOf("name") != -1) {
         // Store the next two lines.
         // You will need to call br.readLine() again.
} catch (IOException x) {
    x.printStackTrace();
}

How to read specific lines from a text file using external table or any other method?

Hi,
I have a text file with delimited data, I have to pick only odd number rows and load into a table...
Ex:
row1: 1,2,2,3,3,34,4,4,4,5,5,5,,,5 ( have to load only this row)
row2:   8,9,878,78,657,575,7,5,,,7,7
Hope this is enough..
I am using Oracle 11.2.0 version...
Thanks

There are various ways to do this. I would be inclined to use SQL*Loader. That way you can load it from the client or the server and you can use a SQL*Loader sequence to preserve the row order in the text file. I would load the whole row as a varray into a staging table, then use the TABLE and MOD functions to load the individual numbers from only the odd rows. Please see the demonstration below.
SCOTT@orcl12c> HOST TYPE text_file.csv
1,2,2,3,3,34,4,4,4,5,5,5,,,5
8,9,878,78,657,575,7,5,,,7,7
101,201
102,202

You can get the reference by a dirty assign, but this is not offcially supported...
But if you have some limitations.
FORM user_command USING fuw_ucomm LIKE sy-ucomm

Reading one line from a text file into an array

i want to read one line from a text file into an array, and then the next line into a different array. both arays are type string...i have this:
public static void readAndProcessData(FileInputStream stream){
     InputStreamReader iStrReader = new InputStreamReader (stream);
     BufferedReader reader = new BufferedReader (iStrReader);
     String line = "";
     try{
     int i = 0;
          while (line != null){
               names[i] = reader.readLine();
               score[i] = reader.readLine();
               line = reader.readLine();
               i++;
          }catch (IOException e){
          System.out.println("Error in file access");
this section calls it:
try{
     FileInputStream stream = new FileInputStream("ISU.txt");
          HighScore.readAndProcessData(stream);
          stream.close();
          names = HighScore.getNames();
          scores = HighScore.getScores();
     }catch(IOException e){
          System.out.println("Error in accessing file." + e.toString());
it gives me an array index out of bounds error

oh wait I see it when I looked at the original quote.
They array you made called names or the other one is prob too small for the amount of names that you have in the file. Hence as I increases it eventually goes out of bounds of the array so you should probably resize the array if that happens.

How to read multiple documents from a system directory?

Hi,
I'm trying to read multiple documents from a specific folder that contains pdfs, jpgs... the only activity I found is the Read Document, but this activity does not have the option to read all docs under my folder!.
so any one can tell me if there is another activity can do it or is there any good solution to loop on the folder and read all the docs? any script will be helpful.
Thanks
Hussam

Hi,
After many hours of searching and readings, I found a solution, I do not know if it is the best, but anyhow this is my solution:
By using a service operation called "Find" from a service named "FileUtilsService", this operation will return a list of strings with the names of all files and/or directories under the path you want.
Then by using the "Read Document" I was able to get one file and store it in a dcoumnet variable, and by using a simple looping technique I got all the files I want.
hope this will help others

Sorry I'm just beginning coding and I'm still a noob. Any help is appreciated. Thank you!

Ok, so if I'm following this correctly you should be able to just loop through all of the files in that folder whose file name matches the pattern and then read the first 22 lines, recording only the first and the last.
Exactly how you store the animal data probably depends on how you are going to display it and what else you are going to do with it. Is there anything other than name and cage number that should be associated with each animal?
You might want to make a dataset with a datatable to describe the animal, or you might write a class, or you might just use something generic like a Tuple. Here's a simple class example:
Public Class Animal
Public Property Name As String
Public Property Cage As String
Public Overrides Function ToString() As String
Return String.Format("{0} - {1}", Name, Cage)
End Function
End Class
With that you can use a routine like the following to loop through all of the files and read each one:
Dim animals As New List(Of Animal)
Dim folderPath As String = "E:\Furry Friends Animal Shelter Solution\Furry Friends Animal Shelter\"
For Each filePath As String In System.IO.Directory.GetFiles(folderPath, "Report Q?.txt")
Using reader As New System.IO.StreamReader(filePath)
Dim lineIndex As Integer = 0
Dim currentAnimal As New Animal
While Not reader.EndOfStream
Dim line As String = reader.ReadLine
If lineIndex = 0 Then
currentAnimal.Name = line
ElseIf lineIndex = 22 Then
currentAnimal.Cage = line
Exit While
End If
lineIndex += 1
End While
animals.Add(currentAnimal)
End Using
Next
'do something to display the animals list
Then you might bind the animals list to a ListBox, or loop through the list and populate a ListView. If you decided to fill a datatable instead of making Animal instances, then you might bind the resulting table to a DataGridView.
There are lots of options depending on what you want and what all you need to do.

Read specified line from a text file

Hi,
I am trying to read a specific line from a text file. I don't want to read all of it but just this specific line... say line number 2. Is there a method built-in in java or should I code this myself?
Thanks and regards,
