How to read a whole text file into a pl/sql variable?

Hi, I need to read an entire text file--which actually contains an email message extracted from a content management system-- into a variable in a pl/sql package, so I can insert some information from the database and then send the email. I want to read the whole text file in one shot, not just one line at a time. Shoud I use Utl_File.Get_Raw or is there another more appropriate way to do this?

How to read values from Property file into BPEL process local variable?

I would like to use a Property file with some parameters e.g.
<myparm1>12345</myparm1>
How can I read from a BPEL process such a Property file and assign it into e.g. local variable "intparm1"?
Where (in which directory) should I put this XML Property file to have it always available for reading?
Peter

Hi,
You can also use
ora:readFile( ) function as follow :
ora:readFile(xml file location (ex. "file:///D:\\SOA\\FileAdapters\\readFile\\test\\test.xml"),xsd file location (ex."file:///D:\\SOA\\FileAdapters\\readFile\\test\\test.xsd"))
inside the assign activity and assign this to the variable you want.

How to read in a text file of race lap times....

How do i read in a text file containing lap times from a race for one driver?
I have the times down 1 column and look like this.
I then want to add the times up to get a total race time. I have been looking at the Calendar class and the simpleDateFunction but not sure how to go about it.

Considering that your times have non-numerical chars you have no choice but to read them as Strings. Once you have done that you will need to parse the times yourself, ie spilt it into the three separate bits of data. Then you can use the Calendar class if you wish or you can keep a running tally yourself. Just don't forget to tick over seconds when milliseconds reaches 999 and tick over minutes when seconds reach 59.

How can i feed a text file into a Hashtable?

Hi,
im working on my third year project, im new to java and am struggling a little with writing the code.
I need to feed a text file into my program and insert it into a hashtable. I presume i'll be using an input stream to feed the file in, how do i go about placin the text file into a hashtable??
please help!

ok, so im trying to code an authorship attribution
program. the first part of the program need to
compare a text file A (list of words), with another
two text files B and C. Compare how? Do you want to know how many times certain words from list A appear in files B and C?
The words in list A will first be compared to those
in list B and than list C. I was wondering if there
was a way of inserting file A,A Map is a list of key/value pairs, so what do you mean by inserting here? What are you inserting? What would the keys and values here be?
followed by B,
comparing the two files.....than inserting file C and
comparing it with A??
Does this make sense??Not quite, but it might just be me.

How to read from a text file one character at a time?

Some additional comments:
You really don't want to read any file one character at a time, because it is highly inefficient. More typically, you read the entire file into memory with one operation (or at least a large chunk, if the file is gigantic) and then do the rest of the operations in memory. One easy way to analyze it one byte at a time would be to use "string to byte array" and then autoindex into a FOR loop, for example.
Of course you could also read the file directly as a U8 array instead of a string.

How to read a Unicode text file in a non-unicode SAP system

I'm currently has a text file which is saved as UTF-8 format. And inside this file has Thai characters.
However, my SAP system is a non-unicode system.
When I use the code
open dataset DSN for output in TEXT MODE encoding UTF-8
the thai characters become some funny characters.
How can I solve this in the ABAP program without changing the system from non-unicode to unicode system?

Hi Eswar,
   How can I check whether the code page for THAI already installed or not in SAP system?
   Here is the code I use to test to read a file that saved as UTF-8.
DATA: l_filepath         TYPE string.
DATA : BEGIN OF l_filepath_str OCCURS 0,
             comm(1000) TYPE c,
           END OF l_filepath_str.
DATA: l_datasetsucc LIKE rlgrap-filename.
l_filepath = '/BAAC/Files/APP_.txt'.
OPEN DATASET l_filepath FOR INPUT IN TEXT MODE ENCODING UTF-8.
IF sy-subrc EQ 0.
DO.
    CLEAR l_filepath_str.
    READ DATASET l_filepath INTO l_filepath_str.
    IF sy-subrc EQ 0.
      APPEND l_filepath_str.
    ELSE.
      EXIT.
    ENDIF.
ENDDO.
ELSE.
WRITE:/ 'Error reading from file:', sy-subrc.
ENDIF.
CLOSE DATASET l_filepath.
LOOP AT l_filepath_str.
WRITE: / l_filepath_str-comm.
ENDLOOP.
    It returns me a runtime error. Any idea?

How can I combine multiple text files into a single, alphabetized list?

I have many, many lists of song titles. Each in its own textedit file. There is tons of overlap and duplication. I want to make a master list that has every song listed.
If I could somehow just merge them all and alphabetize the lines, I could manually get rid of duplicates fairly easily.
I have Tiger. Don't know if I have any application that would help. I probably don't want to buy an application, though, because I suspect I may not be able to stick with Tiger much longer.
I appreciate any tips you can give me.
Thanks a lot,
Bruce

Hi Bruce, Tex-Edit Plus for OS X...
http://www.tex-edit.com/
It can Merge files then Sort them easily, even has a remove duplicate lines script available.
If the version you get doesn't have the sort perchance, here's a link, put sort in the search scripts box, get the second one, Sort Selection...

Read words from a text file into an undefined array

Dear all,
Does anyone know how to read words in text file, seperated by all types of spaces ("_", "\n", "\t","\r","\f") and put them into a string array to be used later?
So far I can read the words using the Tokenizer but can't assign to array:
public class reader
StringTokenizer tokenizer = new StringTokenizer(input);
String[ ] array= null; //unknown size of array
int i=0;
               while(tokenizer.hasMoreTokens())
                         array[i] = tokenizer.nextToken();
                         i++;
Any suggestions welcome!
thanks in advance!

Hi
sorry wrote in a hurry ;) din c the problem clearly
there are two approaches
1) best approach for your problem is Vector or ArrayList, these would make life easy for you.
Always collections are better approach over arrays when the size is dynamic. However in your case the size cant be said to be DYNAMIC. coz the number of words will not grow / shrink during the runtime.. i know that number of words are not fixed but dynamic is something which will grow/shrink during runtime. but still collection is better approach.
2)dirty approach
use double dimensional array
String arr[][] = null;
then use one tokenizer for StringTokenizer(str,"\n");
using countTokens on this will give you number of lines.
use this to initialize array
arr = new String[lineCount][];
then iterate from 1 to lineCount and use 1 more tokenizer to get number of words for that line. use this number to initialize the column size for arr[i] like
arr[i] = new String[wordCount];
then store the token using nested for loops in this array
go for the 1st one ;) 2nd one is hedious n time consuming but both will work ;)
cheers

Reading a text file into a StringBuffer?

Hey all,
I've taken a year of Java programming class so far, but I doubt my class is ever going to get in to things like this. I've been trying to develop a program that reads a small text file into a StringBuffer for manipulation and use in the program. I've been looking around the web, but thus far all I've seen are things like FileInputStream, in the java.io.* package; nothing about StringBuffers.
And I'm pretty sure it's kind of hard, too. If someone could give me a simple(?) explanation, or a link to a tutorial that shows you this or something, it would be much appreciated.
Also, is it possible to pull an integer out of a string? I was just wondering this, I don't think you can cast a string to an int or anything. Ha ha.
