Hi, I am trying ti use DBI for accesing my oracle table which have 100,000 rows.FRom various articles i read fetchall_arrayref with binding () the colums give the fastest fetch .I am trying to fetch one row from database and to an array and first element is pushed as key and rest will be pushed as value which is an anonymous array. 
my $sth = $dbn -> prepare("select number,id,start_dat,end_dat from SUB
+SCRIBERSLIST");
$sth -> execute();
$sth->bind_columns(\$number, \$id,\$start_dat,\$end_dat);

my $max_row=5000;
my $rowcache;
my %hash =();

while (my $aref = shift(@$rowcache)
|| shift ( @{$rowcache= $sth->fetchall_arrayref(undef, $max_rows)} )
)
{
        # $aref now contains only one row
        push @{$hash{$aref[0]}}, [ $aref[1],$aref[2],$aref[3] ];
};


$sth->finish();
$dbn->disconnect;

is it the right way to get the fastest fetch?
