Thanks choroba,

Where in my code did I assign anything to @AoH directly via "@AoH = ..." apart from at the very beginning?

    Sorry, you assigned to @age_ref directly. 
    while (@age_ref = \$sth->fetchrow_array)

      OK thanks choroba,

      Using the @AoH that I have (as it is), is there a way I can rewrite this line:
      while (@age_ref = \$sth->fetchrow_array)
      so that it replaces the age values in @AoH, maybe using similar principles to those which allow this to update the age values:
      ($age_ref0,$age_ref2) = (\$AoH[0]{age},\$AoH[2]{age});

      If not, what's preventing this?

my @AoH = ( { age => \ do { my $tmp = 42 } },
            {},
            { age => \ do { my $mpt = 33 } } );

my @age_ref = \($AoH[0]{age}, $AoH[2]{age});

(${ $age_ref[0] }, ${ $age_ref[1] }) = (1, 2);

use Data::Dumper; print Dumper \@AoH;
