do-commands is intended for DDL. All of these API methods are intended to be used inside (with-connection ...) which is how they know which DB connection to use. Again: Perhaps you can explain a bit more about what you're trying to do. Have you looked at this page: http://clojure.github.com/java.jdbc/doc/clojure/java/jdbc/UsingSQL.html
I will read over that page. I have no experience with Java, which would probably help as there seem to be an abundance of Java examples on related topics. Right now I'm trying to run this query against a MySql database: select u.first_name, u.last_name, sum(p.amount) as amountTotal from sf_guard_user_profile as u, payment_outgoing_for_answers as p where u.user_id=p.user_id group by p.user_id order by amountTotal ; I can not figure out what command to use. The examples all look like this: sql/with-connection db but I am assuming I would get terrible performance if I use with-connection, since I need to make several queries.
