Ron,
Thanks for the suggestions. But, wouldn't it just be better to switch back
to using fetchrow_array()? Is there any advantage to using bind_columns in
this case?

Glad you're taking it the right way!

Why can't you use @rowvalues here?

If you don't change the call to bind_columns(), why can't you use:
for my $column ($elementresult_id, $element_id,
$quantification_id, $signal)
here? That saves copying the info into @rowvalues.

That makes me think the problem really is you lack of RAM.
