Ok. Good enough, and good explanation for why. That's exactly what I was
looking for. Guess I'll keep typing that extra line :-). Thanks much.

Perl has to copy every column value returned by fetchrow() to the
corresponding element of @array. With bind_columns(), no copying is
required. That is a major performance improvement if you have more than a
few rows.

I normally use
while ( $sth -> fetch ) {}
with $dbh -> {RaiseError} = 1. Once you've bound the parameters, there's no
need to copy even the reference.
