@alice you can do it like

Always happens, I think something's too niche for a channel and it exists

Sorry for polluting beginners

it's fine

i'll show you how i did it and you decide if it's good for your use case

-- :name use-authz! :<! :1
update oauth_auths
  set used = true
  where
    (not used) and
    client_id = :client-id and
    auth_code = :auth-code and
    expires_at > now()
  returning user_id, app_id, scopes

This is my first time using sql for a project only I am working on, all the other times in the past I had others help me with that, so I'm not sure I really know what that means 😞

oh. well for an update statement you can write it like

UPDATE table
SET column1 = value1, column2 = value2, column3 = value3
WHERE condition

The ideal function I want is one that will take a user map and update all the existing fields in the map, but I think doing it like that would lead to nils if the values weren't supplied right

actually hugsql would throw an error about a missing key

Hmm, well is there a way to get what I want?

so it's like, you have a white list of updatable columns, and if any of those are present in the hashmap you want them updated and untouched otherwise

correct?

Correct

i never did that myself with hugsql yet, but there is something promising in the docs

you need to mix the clojure and the sql https://www.hugsql.org/#using-expressions

i'm still trying to figure it out just a mo

Thanks so much for taking the time

Oh that's an interesting solution

-- :name alice-update :! :1
/* :require [clojure.string :as string]
            [your-namespace :refer [column-whitelist]]
            [hugsql.parameters :refer [identifier-param-quote]] */
update :i:table set
/*~
(string/join ","
  (for [[field _] (select-keys (:updates params) column-whitelist)]
    (str (identifier-param-quote (name field) options)
      " = :v:updates." (name field))))
~*/
where id = :id

i don't exactly understand myself how parameters are passed around in hugsql so i just tweaked that example to include a colum whitelist

maybe this way:

-- :name alice-update :! :1
/* :require [clojure.string :as string]
            [your-namespace :refer [column-whitelist]]
            [hugsql.parameters :refer [identifier-param-quote]] */
update your-table set
/*~
(string/join ","
  (for [[field _] (select-keys params column-whitelist)]
    (str (identifier-param-quote (name field) options)
      " = :v:" (name field))))
~*/
where id = :id

(def column-whitelist [:field_1 :field_2])
(update-thing {:id 42 :field_1 "value" :field_2 "value" :invalid_field "value"})

oh wow

well thanks that's fairly elegant

and a lot better than what I was doing lol, thanks so much

✌️
