The docs[0] say of quick_select:

 returns either the first matching row as a hashref if called in scalar
 context, or a list of matching rows as hashrefs if called in list
 context

You're assigning that to a hash; that implies list context, so your
hash will have both keys and values representing rows.

e.g. you'll end up with a hash looking like:

  (
      'HASH(0x5356)' => \%row1,
      'HASH(0x5367)' => \%row2,
  )

etc.

You want to assign straight to a list:

  my @allCommandeBNP = database->quick_select('CommandeBNP', {} );

Then pass that straight to your template, e.g.

  ccmd => \@allCommandeBNP,

And in your template, just iterate over that.
