null value in column "subject_id" violates not-null constraint
and this is nothing but column A which I talked about in the very beginning! Since its not null how can I COPY to B C and E. The same problem will arise with field E too!

Thanks for the chmod command Pandu but the cat command is not doing anything!
And as Michael suggested that file has indeed carriage returns embedded in fields. I opened it in my windows m/c using textpad and got:
B1
C1
E1
B2
C2
E2

Any more suggestions on how to solve this? :(--On 1/6/06, Pandurangan R S <pandurangan.r.s@xxxxxxxxx> wrote:To get rid of ^M characters you could use
cat file | tr -d ^M
you need to type ^V before you type ^M in the preceeding command. But
^V will not be displayed on the screen.
You might need to change directory permission too.
use chmod +rx <username>.
For this command to succeed you need to execute this command as root
or the owner of the directory
