RE: anyway to determine # rows before fetch loop ends and without seperate count(*)

Read standard books such as _Programming Perl_ by Wall etc. for information
on array references.
Generally references are the most efficient way to pass arrays around or
return them from a function. Returning an array instead of a reference to
an array means the whole array has to be copied. Array references avoid
that. An array reference is not a two-dimensional array.
selectall_arrayref() returns an array reference.
Maybe you still need to work on this issue, but it's off topic for this
list.

Well I'm not seeing why a number of arrays that each point to arrays
could not be consider a matrix of arrays when considering one definition
of the word matrix "Something resembling such an array, as in the
regular formation of elements into columns and rows". I dunno, i'm not
trying to argue with you of course. It is apparent that I truly am
confused with Perl References again. I beleive my main mistake could be
using "foreach my $record (@{ $results })" instead of what you've shown
"for my $record (@{ $results })". I'll test this later when I get a
chance and also see how I can include the use of bind variables while
using this method as well.
I appreciate your help an explanations.
