I read Web Development with Clojure, 3rd Edition and got stuck at:
; Jack-in done.
clj꞉user꞉> (in-ns 'guestbook.db.core)
#namespace[guestbook.db.core]
clj꞉guestbook.db.core꞉>
(conman/bind-connection *db* "sql/queries.sql")
; Syntax error compiling at (.calva/output-window/output.calva-repl:1:8039).
; No such namespace: sql
What did I do wrong?
