Here is my attempt at gymnastics, exploits that < does indeed resolve to
clojure.core/< in datomic query:
(def c 5)
[:find '?e :where ['?e :db/ident] [`(< ~'?e ~c)]]=> [:find
?e :where [?e :db/ident] [(clojure.core/< ?e 5)]]
(d/q [:find '?e :where
['?e :db/ident]
[`(<
I wouldn't try to fight this battle, just parameterize the query
[:find ?e :in $ ?three :where
[? :data/number ?number]
[(> ?number ?three)]]
http://docs.datomic.com/best-practices.html#parameterize-queries
*Datomic will cache queries, so long as the query (first) argument data
structures ev
Also:
(cond-> query
true
(conj ['? :data/number '?number])
true
(conj [(list '> '?number (foo 2))]))
;; => [:find ?e :in $ :where w [? :data/number ?number] [(> ?number 3)]]

Hi guys I need your help.
I want to make a clojure query, but the :where conditions are condition. SO
i used cond->.
this works well. but now my problem is that I want to make a clojure
function call inside a (') or quote.
(defn foo [num]
(inc num))
(def query '[:find ?e
:in
