in reply to DBI and binding a list of hashes

I'm not sure I understand what exactly you are asking for. There is pretty good documentation about column binding in the DBI documention. To wit, the documentation for bind_columns() shows an example:

$dbh->{RaiseError} = 1; # do this, or check every call for errors $sth = $dbh->prepare(q{ SELECT region, sales FROM sales_by_region }); $sth->execute; my ($region, $sales); # Bind Perl variables to columns: $rv = $sth->bind_columns(\$region, \$sales); # you can also use Perl's \(...) syntax (see perlref docs): # $sth->bind_columns(\($region, $sales)); # Column binding is the most efficient way to fetch data while ($sth->fetch) { print "$region: $sales\n"; }

If you keep reading the documentation for that method, they even show an example of binding to values inside a hash.
