@clojurians827 I just tried putting this single definition in a file by itself and def-db-fns works fine. The "SQL is empty" error occurs when the parser is given an empty string, so maybe make sure that you're passing in the correct file or string if you're pulling in non-file data with def-db-fns-from-string or similar.

thanks for checking it out! I'm in a luminus project with conman wrapping hugsql, so maybe something is going on there. I'll dig deeper into that question.
