Hello, if I want to run some sql code in a transaction, I can do this (where clojure.java.jdbc is referred to as j):
(j/db-transaction [conn dbspec] use conn here But if I have a function I want to call from this transaction, say to do a query, then I need to pass in the connection to that function: (defn query [conn] do query on conn...) (j/db-transaction [db dbspec] (query conn)) I am trying to decide whether I like passing in the connection to query, or whether I would rather use a binding like so: (def ^:dynamic *conn*) (defn query [] do query on *conn*...) (j/db-transaction [conn dbspec] (binding [*conn* conn] (query))) Looking at the jdbc docs, I notice that this style used to be directly supported but is now deprecated. Does that mean it's a bad idea to re-implement on top of the supported API, as my example would? Can someone explain the tradeoffs involved?
