thanks for your replies
I had already set the utl_file_dir parameter
I tried the utl package and wrote the following code but got some errors
declare
filehandler UTL_FILE.FILE_TYPE;
begin
filehandler:=UTL_FILE.fopen('d:/intel/','myfile.txt','w');
utl_file.put_line(filehandler,'look masjdfgsd\n');
utl_file.fclose(filehandler);
exception when utl_file.invalid_path then
raise_application_error(-20023,'bhrigu ,chk the path');
end;
the errors
ERROR at line 1:
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "SYS.UTL_FILE", line 101
ORA-06512: at "SYS.UTL_FILE", line 157
ORA-06512: at line 4
if u know what this is please tell me
thanks bhrigu

U need :
1) To have UTL_FILE_DIR param in the init file of the instance with the same directory (don't forget to stop and restart the base)
2) Handled the exceptions listed in the utl_file package (Oracle_home\rdbms\admin\utlfile.sql) in your source.
3) Turn set serveroutput on in SQL*Plus.
Run your procedure and see the error message to debug.
Good luck

I was given an assingment, but have no idea where to begin. The assingment is to create a text file using notepad with all of my digital inputs and some how make those imputs show up on my digital indicators on my control pannel

When it was explained to me it didn't sound to hard of a task, I have no LabVIEW experience and the tutortial sucks.

StevenD: FYI, I did NOT give you the one star rating. I would never do that!

Well, this is an assignment, so it is probably homework.
Why else would anyone give HIM such an assigment, after all he has no LabVIEW experience and the tutorials are too hard for him?
This would make no sense unless all of it was just covered in class!
This is not a free homework service with instant gratification.
OK! Let's do it step by step. I assume you already have a VI with the digital indicators.
"...but have no idea where to begin".
open notepad.
decide on a format, possibly one line per indicator.
type the document.
close notepad.
open LabVIEW.
Open the existing VI with all the indicators.
(are you still following?)
look at the diagram.
Who made the program?
Does the code make sense so far?
Is it a statemachine or just a bunch of crisscrossed wires?
Where do you want to add the file read?
How should the file be read (after pressing a read button, at the start of the program ,etc.)
See how far you get!

Spool SQl data into text file using dynamic sql

Hi,
I am spooling output data into text file using command
select 'select t.mxname,bo.lxtype,t.mxrev'||chr(10)||'from mx_1234567'||chr(10)||
'where <condition>';
here mxname varchar(128),lxtype(128),mxrev(128) all are of varchar type.I want the output in format
e.g Part|1211121313|A
but due to column width the output,I am getting is with spaces.
"Part then blank spaces |1211121313 then blank spaces |A"
how can I remove these spaces between columns.I used set space 0 but not working.
Thanks in advance.
Your help will be appreciated.

Hi Frank,
I have seen your reply for SET LINE SIZE function. But, I could not be able to understand it.
I am facing similar kind of issue in my present project.
I am trying spool more than 50 columns from a table into flat file. Because of more column lengths in few columns, i am getting space. There are so many columns with the same issue. I want to remove that space.so that, data can fit perfectly in one line in .txt file without any wrap text.
Below is my sample query.sql. Please let me know the syntax. My mail id : [email protected]

Please Advice ....in case if you are have an example please share it.
Thanks for your helps

How do I create a binary file using PL/SQL

Hi
Can you help me with writing a binary file in PL/SQL? I like to load binary data from data file, process in database then write to a new binary file.
Thank you very much in advance.

DBMS_LOB won't help you write a BLOB to disk.
You need to an external procedure to do that. Eric K's java works great and he's helped me with his solution and probably about a thousand others.
Doing a search on this forum will yield many discussions on this often regurgitated topic.

Create a Multiple Files using PL-SQL

I have a table which contains 360 records and want to create multiple files with each file containing 12 records.
I tried to use the below code, however was unsuccessfull..
Please help!!!!
DECLARE

CLOSE c_cur;
END;

Thanks Ramin,
Your Code really helped. I am now not getting no errors and files are also being created. However, if I replace the UTL_FILE with DBMS_OUTPUT, I get below output. In your code i replaced 12 with 3. Hence its dividing after 3 rows. (with 1st row duplicated)
Output

Now my concern is that i my table I have a flag which determines the seperation...
Column1
File_Num

Hence if the file_Num is 1 it will go to File1, file_num=2 will be written to File2 and so on.
Please help me to get this logic.
Thanks in advance.

My problem:
1)
I am not able to write to the file. I want to know, where i am going wrong.
It is giving error message like
"Canot resolve Symbol: temp,"
But, FileWriter Constructor should accept a File type parameter.
here temp is a file parameter.
If i am not using file=new file();
i can't delete the file after the use. i.e if i use

Thank you Ram,
But, i want to create a text file in Append mode.
for that i used
FileWriter fos = new FileWriter(temp,true); But, it is not accepting FileWriter constructor in
this format. if i use
FileWriter fos = new
FileWriter("c:/ash/cute.txt",true); it works fine. !!!!!Here's the javadoc
public FileWriter(File file,
boolean append)
throws IOExceptionConstructs a FileWriter object given a File object. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
Parameters:
file - a File object to write to
append - if true, then bytes will be written to the end of the file rather than the beginning
Throws:
IOException - if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason
Since:
1.4
Are you using jdk.13 or lower ?
>
ONe more doubt, Does flush method deletes a file?
if not, then i need to use
File temp=new File("c:/ash/cute.txt");
FileWriter fos = new FileWriter(temp,true); //which
is again a problem
if(temp.delete())
out.println("File is deleted");
}I don't know whether i am taking it wrong ! or
anything wrong with my coding ! but, after creating
and writing data into a text file. I must delete it
as it contains confidential informations.
Regards,
Thanks.'flush' writes to a file immediately. Else you should explicitly call 'flush' to write contents from buffer to underlying source.
javadoc again
PrintWriter
public PrintWriter(Writer out,
boolean autoFlush)Create a new PrintWriter.
Parameters:
out - A character-output stream
autoFlush - A boolean; if true, the println, printf, or format methods will flush the output buffer
cheers,
ram.
Question; What do you gain by opening a file, writing to it and deleting it in the same program ?

Reading Text Files using Oracle PL/SQL and UTL_FILE

Hi, experts. I tried to read a text file into oracle. Here is what i did:
1. Create a text file in the directory: C:\temp\New Text Document.txt
2. Run the following SQL in PL/SQL:
CREATE or replace DIRECTORY sampledata AS 'C:\temp\';
grant read, write on directory sampledata to public;
3. When I run the following code, it caused an error: ora-29280: invalid directory path. I have alread checked the directory path, it is correct. Would someone know what wrong is my code?
declare
f utl_file.file_type;
s varchar2(3000);
begin
f := utl_file.fopen('sampledata','New Text Document.txt','R');
utl_file.get_line(f,s);
utl_file.fclose(f);
dbms_output.put_line(s);
end;
Thank you

Try with a filename without spaces:No problem with spaces
SQL> declare
2 f utl_file.file_type;
3 s varchar2(3000);
4 begin
5 f := utl_file.fopen('SAMPLEDATA','New Text Document.txt','R');
6 utl_file.get_line(f,s);
7 utl_file.fclose(f);
8 dbms_output.put_line(s);
9 end;

Creating Files Using PL/SQL?

Hi,
Is there a way to create a file using PL/Sql? It seems that the
utl_file package doesn't allow you to create a file. It only
allows you to read, write to a file that already exists there.
Thanks
Vic

Make sure the following is set in the init.ora:
UTL_FILE_DIR = /path/to/your/file/directory (for unix)
or
UTL_FILE_DIR = <drive>:\path\to\your\file\directory (for windows)

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.
I attach my code here.

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.
