Clojurians Log v2

Heya, I have a short question about java.jdbc. In the example this is provided:

(j/query mysql-db
  ["select * from fruit where appearance = ?" "rosy"]
  {:row-fn :cost})

Under the hood clojure.java.jdbc and next.jdbc both use PreparedStatement objects, which you can read about here: https://docs.oracle.com/javase/tutorial/jdbc/basics/prepared.html

The relevant bit is "Prepared statements always treat client-supplied data as content of a parameter and never as a part of an SQL statement."

Thank you!
