e.g. (pathom [{[:t_patient/patient_identifier 14032] [:t_patient/id :t_patient/nhs_number]} {[:t_patient/patient_identifier 14033] [:t_patient/id :t_patient/nhs_number]}]) => {[:t_patient/patient_identifier 14032] #:t_patient{:id 17490, :nhs_number "1231231234"}, [:t_patient/patient_identifier 14033] #:t_patient{:id 14033, :nhs_number "1111111111"}}

I have a situation in which I don't really want to use a placeholder to add nesting, but am running two queries with the same initial ident - the second has parameters set on one of the joins.

hi Mark, in this situation I would say you have many inputs, but still a single query. the way I suggest you handle this is by using an entity input, so you send a value that is a vector with all the entities you wanna query for, and them you query that vector, here is an example:

(ns query-many-entities
  (:require [com.wsscode.pathom3.connect.indexes :as pci]
            [com.wsscode.pathom3.connect.operation :as pco]
            [com.wsscode.pathom3.interface.eql :as p.eql]))

(pco/defresolver patient-nhs-number
  [{:keys [t_patient/patient_identifier]}]
  {:t_patient/id         (str "ident - " patient_identifier)
   :t_patient/nhs_number (str "nsh number - " patient_identifier)})

(def env
  (pci/register [patient-nhs-number]))

(def request (p.eql/boundary-interface env))

(comment
  (request {:pathom/entity {:patients [{:t_patient/patient_identifier 14032}
                                       {:t_patient/patient_identifier 14033}]}
            :pathom/tx     [{:patients [:t_patient/id :t_patient/nhs_number]}]}))

does that work for you?

Thanks @U066U8JQJ - I'm trying an experiment and one query will be normalised, but another on the same ident will be pulled in denormalised - but I think I'm probably going in the wrong direction. Thanks you for suggestion however!
