hello,

using DBI and Template Toolkit.

my webapp needs to fetch 100-300 rows with 5-6 columns and display them using Template. i don't want to reference each col by index from my template so i chose to fetch hashref. what i have is something like: 

    my $sth = $dbh->prepare_cached( $sql );
    $sth->execute( @bind_vals );
    $result = $sth->fetchall_hashref( $name );
    $tt->process("result.tt", { result => $result })

but knowing that fetchall_hashref being the slowest among fetchall_arrayref and fetchrow_arrayref. i tried to use bind_columns and fetchrow_arrayref : 
    my ( %row , @rows );
    $sth->bind_columns( \( @row{ @{$sth->{NAME_lc}} } ) );
    while ( $sth->fetchrow_arrayref ) {
        my %row_copy = %row;
        push @rows, \%row_copy;
    }
    $tt->process("result.tt", { result => \@rows })

i got all result in nice AoH structure. but that defeats the purpose of bind_columns.

the DBI example of using bind_columns are fine as it prints out the fetched result in each loop. I can't do that and still use my template.

so my question is how do you use bind_columns with Template that require you to collect all results first?

UPDATE: my last sentence is bit misleading. i am wondering if there are better way to achive the same goal?
