this actually already exists and is very useful. the method you're looking for is fetchall_arrayref( {} )

from the docs:

"When passed a hash reference, fetchall_arrayref uses /fetchrow_hashref to fetch each row as a hash reference. If the parameter hash is empty then fetchrow_hashref is simply called in a tight loop and the keys in the hashes have whatever name lettercase is returned by default from fetchrow_hashref."
and
"To fetch all fields of every row as a hash ref:
$tbl_ary_ref = $sth->fetchall_arrayref({});  "

going through each row then looks something like:

foreach my $hashref_row (@$tbl_ary_ref) { foreach my $field (sort keys %$hashref_row) { my $value = $hashref_row->{$field}; } }

there's a good chance my use of references is off in the 3rd line, but at least I tried :)

hope that's what you were looking for!

[thezip]: Is there an analogy for '&' (ie. run commandline process in background) for Windows commandline?
[Corion]: thezip: start "some title" path\to\that\ application, but that will open another console window
[Corion]: thezip: If you want to confuse your users, use system(1, "that\\command" );, which will make Perl launch it in the background
[Corion]: That will keep the console window open even though the user can't type into it anymore
[thezip]: So I have a script that generates a log file. After script completion, I want tohave VIM open this logfile.
[thezip]: i don't get the command line "back" until I close VIM. No what I want to happen...
