How about a Perl script that uses DBI with autocommit turned on and
loops over the file using (something like) 'while (my @line =
split(',',scalar(<>)) {}'?
Perl tracks the line number of the current input file (including
STDIN) in $. (dollar-period). If you get a DBI error, 'warn "Input
error at line $.\n";'.
