How to get the hash keys and values of a hash in perl mojo

I try to figure out how to select explicit key and values of a hash.

my $hash = query('select id, name, required from table')->hashes

My output when I dump is:

var1 = bless ([
              {
               'name' => value,
               'id' => value,
               'required' => value
           }.....
])

What I want is to get the follow output:

var1 = bless ([
              {
               'required' => value
              }...
])

After that I want to compare if the index == index of another array.
