I don't know about best, but I would use Perl.

C/C++ might run faster, but not the best option for a tight deadline.

Attached is a script that should work as is with the Perl that is installed
with Oracle.

You will need to modify the SQL bit.

Also, if Getopt::Long is not installed in your perl, you can just use the
@ARGV array to get
command line options, or hardcode them in the script.

Buffering is disabled in the script, at least as much as possible.
