Didn\'t work which I ki

Answer 1

to use insert! to insert a vector of strings you must create an object (from the vector of strings) that implements java.sql.Array. You can use java.sql.Connection.createArrayOf to create such object

(def con (sql/get-connection db))

(def val-to-insert 
    (.createArrayOf con "varchar" (into-array String ["cow", "pig"]))

(sql/insert! db :things {:animals val-to-insert})

and

clojure.java.jdbc's docs on execute! said

(execute! db-spec [sql & params] :multi? false :transaction? true)
(execute! db-spec [sql & param-groups] :multi? true :transaction? true)

Your must put your sql string in a vector to make it work.

(sql/execute! db ["INSERT INTO things (animals) VALUES ('{\"cow\", \"pig\"}')"])
