Hi,

Is it possible to load data from a text file to other one text file using SQL LOADER?
I knew that from excel we could load the data into Oracle table.
Now i suppose to import from a text file to other text file.. can we do it using SQl LOADER...

That's not the purpose of a database. You would use an operating system for that. However, with UTL_FILE you can read and write OS files. Perhaps that's more what you're looking for.

yes. exactly im looking for that.
Just i want to know whether it could be done using loader? have gone through one document, even i tried using input/output as flat file.

it says sql loader is expecting TABLE keyword. now im clear.
so no option in sql loader that do flat to flat transaction.

If possible can anyone provide me the UTL_file program which reads a flat file (that is comma delimited) and write it in other one text file...

The purpose of SQL*Loader is to load a flat file into a database table, nothing more.

Your question makes no sense. If you want to copy a flat file to another location in the os then use the OS copy or cp command.

let me make senseful...

I have to read one flat file which has 4 fields and
write it into other one text file, only with 3 fields
based on some sort of filters.

source file willbe in UNIX SERVER-1
Destination file willbe in UNIX SERVER-2
FTP things will happen thru UNIX SCRIPT.

Here i have to do it with oracle procedure to read n write it in a new file.

hope now u got it...

You would be better off with operating system commands such as cut or awk. You could easily cut fields 1,2 and 4 from a comma-delimited file using a command such as:

cut -d"," -f1,2,4 file1.txt > file2.txt

I don't see how you are going to be able to do this as UTL_FILE operates on the server, so you will not be able to read/write to two different unix servers.

Please take this to a unix forum.
This has nothing to do with Oracle.

awk, perl are commonly used for processing text files.
