Oracle table extract: all columns are not converting into pipe delimited in flat file
Hi All,
I am writing a shell script to extract oracle table into a pipe dilemited flat file. Below is my code and I have attached two files that I have abled to generate so far.
1. Table.txt ==> database extract file
2. flat.txt ==> pipe delimited after some manipulation of the original db extract (Table.txt) file.
My challenges:
The table I am extracting has 13 columns, I want all the columns (null or not null) to be pipe delimited. Problem is that after the last column that is not null (for example say 9th column out of 13th) in the flat file is not coming out with pipe '|', rather it shows up as empty space. I am struggling with this and need your kind help to resolve the issue . This is very urgent and I need to have the code ready by next week. Thank you in advance for your help!

I came across a very good script to convert a comma seperated to pipe delimited file in this forum. the script serves most of the requirement but looks like it does not handle embedded double quotes and commas i.e if the input is like

io_pipe
io_pipe(3) Library Functions Manual io_pipe(3)NAME
io_pipe - create a Unix pipe
SYNTAX
#include <io.h>
int io_pipe(int64 pfd[2]);
DESCRIPTION
io_pipe creates a new UNIX ``pipe.'' The pipe can receive data and provide data; any bytes written to the pipe can then be read from the
pipe in the same order.
A pipe is typically stored in an 8192-byte memory buffer; the exact number depends on the UNIX kernel. Bytes are written to the end of the
buffer and read from the beginning of the buffer. Once a byte has been read, it is eliminated from the buffer, making space for another
byte to be written; readers cannot ``rewind'' a pipe to read old data. Once 8192 bytes have been written to the buffer, the pipe will not
be ready for further writing until some of the bytes have been read. Once all the bytes written have been read, the pipe will not be ready
for further reading until more bytes are written.
io_pipe sets d[0] to the number of a new descriptor reading from the pipe, and sets d[1] to the number of a new descriptor writing to the
pipe. It then returns 1 to indicate success. If something goes wrong, io_pipe returns 0, setting errno to indicate the error; in this case
it frees any memory that it allocated for the new pipe, and it leaves d alone.
