Hi Sean,
Half right - It will compile everytime, but not necessary create the
AST everytime:
(let [my-table (-> (table :user)
(select (where (= :id user-id)))
(project [:dateofbirth :gender :zipcode]))]
(repeatedly @my-table))
However I see there are some good thoughts on optimization in this
thread already.
Perhaps is the AST always kept the SQL representation in a field, we
could totally
avoid re-compilation for repeat queries. That would still created the
preparedStatement,
but Im not sure thats a real time-stealer. I'll have to check.
