I would like to change my output on knex query. I have this output:

{
 restaurant_uuid: '123',
 name: 'Sea Bar',
 country_code: 'FR',
 locales: [ 'fr_FR' ]
}

I need to change it to:

{
 restaurant_uuid: '123',
 name: 'Sea Bar',
 country: {
  code: '123',
  locales: ['fr_FR']
 }
}

Could I do it on query? I know I do it at the end of flow on output with a "foreach" on array, but I would like to do it in a good way.
